THE CHIEF STANDS, DESCRIBED IN \ THEIR NUMERICAL ORDER.

SIMAR ROTOTILLERS, LTD. (PICCA.RD, PICTET

AND CO. LTD.). Stand 91

The agrimotors Cu this stand are of a very interesting type, with which visitors to previous Royal Shows will be well acquainted. This year, however, several new models are being shown, in addition to the types formerly dis

played. The principal machine is the model 10, in which a few improvements have been effected. One of these consists of the provision of a starting pulley and belt as an alternative to employing a starting handle.

The model 5 embodies many novel features, and has been specially designed for orchards, nurseries, flower gardens,

etc. The overall width of the machine can be reduced to 14 ins, from the normal of 20 ins., and a new twin miller has been designed, permitting the straddling of the rows.

Petrol, paraffin or alcohol can be used for the engine without necessitating alteration.

A conspicuous feature of all Simar models is the rotary tines.

SIMONIS, LTD. Stand 127 The whole of this stand is devoted to fire appliances of many types. Conspicuous amongst them is the Park Royal light engine with a Renault chassis and 200-250-gallon turbine pump with positive primer and two delivery outlets. The total accommodation is for six officers and men.

Next in importance is the Park Royal trailer pump, the power unit of which is a Renault four-cylindered monobloc of 75 mm. bore and 120 ram, stroke, this being the same as that employed on the fire engine. The pump is a 200-250gallon multi-stage centrifugal type.

One interesting little pump on view is the Lilliput. It is not in itself power driven, but is put under a wheel of any motor vehicle, and will then give a useful 1-iu. jet with a total capacity of approximately 50 gallons. per minute.

ROTARY TILLER CO., LTEi. Stand 132 The Hammond foot rotary tiller is a really extraordinary machine. It has a six-cylindered 96 b.h.p. Continental engine mounted at the front •of the machine and driving through a four-speed gearbox of special design which has an auxiliary gearbox' for the milling rotors at the rear, of the machine. There are two of these rotors, one set vertically above the other, the active rotor is the lower one ; that above it is the cleaner and this runs at a higher speed. The drive to the two rotors is taken via bevel and spur gears in a centre casing to cross-shafts on which are large spur wheels meshing with smaller pinions, the shaft carrying the large wheels driving the lower rotor and the geared-up shaft the other ; final drive in each case is by enclosed chains.

The rotors have curved blades and the machine is so powerful that it can take a 6-ft. cut to a depth of 10 ins, in hard soil and finish up to 20 acres per day. It will break up hard clay land, either wet or dry, and make a tilth of it, and it is claimed thoroughly to aerate the land. The rotors are secured to a drop frame at the back, their depth being regulated by vertical screws, There is a wide single front wheel steered by a worm and worm wheel carried above It.

D28 L. C. RAWLENCE AND CO., LTD. Stand 134 Certain of the products of the Latil factory are here displayed. One of these has never before been shown in this country. It is the T.L.-type tractor, intended for agricultural and road use. It drives and steers on all four wheels, and, when required, can be equipped with remarkable adhesion device, which consists of folding spuds which can be permanently fixed to the wheels and can be brought into service or folded out of the way without necessitating any changing of the pneumatic tyres. It possesses six speeds and combines the qualities of an agricultural tractor of great adhesion with those of a highspeed road tractor of average tonnage. There are two Latil horse-boxes, the bodies of both having accommodation for two animals each and being of English make.

In aildition to these there are a 30-cwt. boxvan, a 5-ton lorry capable also of hauling a 5-ton trailer, an 18-20-seater coach on the B-type passenger chassis, the bodywork being of the all-weather type, and a tilt van, also on the B-type chassis.

MUIR HILL SERVICE EQUIPMENT, LTD. Stand 137

One of the most interesting outfits on this stand is the Fordson tractor, with complete Muir Hill equipment, coupled to a Carrimoce four-wheeled trailer, provided with the Adhesor device, by which any required proportion of the load on the front of the trailer can be transferred to the tractor.

A trailer, which is known as the Universal, is also shown. This is built by Duthie, Large and Co., of Athy. It is constructed to carry 6 tons, has a screw-down small auxiliary wheel at the front and a ball connection for securing it to Fordson and other tractors. The brake lever is at the front, to be within convenient reach of the driver. It controls external-contracting band brakes on the rear-wheel drums. The wheels themselves are of the disc type. The frame is of rolled channel steel.

The particular example we saw was equipped with a single-screw /tipping gear.

JOSEPH DIME. Stand 138 A most interesting and novel type of wheel is to be found on a Fordson tractor shown by this exhibitor. The working faces of each wheel consist, in the example shown, of three circular plates set on edge, but waved in relation to the plane of rotation. These wheels appear to key themselves into the ground in a most curious manner, and, the plates being separate, any soil which adheres can pass out quite freely. No packing of the ground can occur and practically no wheel tracks are left. The machine, when running at some, speed, presents a most curious appearance; in fact, the wavedwheel treads attract the eye almost irresistibly.

LOCOMOBILE ENGINEERING CO., LTD. Stand 139

The Lanz tractor is a 38 h.p., designed to run on heavy oil. It is of the semi-Diesel type, which requires the use of a blow-lamp for starting. It has two cylinders working on the two-stroke cycle, and develops its rated capacity at 650 r.p.m. There is an automatic governor, pump hibrication and pump circulation of the cooling, water. The radiator is built up in sections, which are renewable. The gearing provides for three speeds forward, a reverse and a low, speed for the winding drum. The tractor is mounted on springs both fore and aft. The haulage capacity is 25 tons on good, level roads and 7 tons on gradients of 1 in 7.

EAGLE ENGINEERING CO., LTD. Stand 149

To those who use, or contemplate using, tractors of the Fordson or McCormick-Deering type the exhibits here will be of particular interest, as included amongst them are several extremely practicable types of trailer designed especially for this class of work. Some are equipped with side or end-tipping bodies and others are trailers for particular purposes, such as timber haulage ; the timber type can be adjusted to suit the length of material carried ant is most useful.

The trailers are equipped with an unusual type of balland-s ocket connection, which permits free movement without the possibility of unintentional disconnection, although undoing the trailer is the work of a moment..

Certain improvements have been made in the Eagle hydraulic tipping gear, which is to be found on one model.

A Fordson tractor with complete Eagle equipment, including special wheels and front cross-spring, is also shown, together with several types of telescopic-screw tipping gear. WILLIAM 'VINCENT. Stand 154

All those interested in the transport of horses by road should certainly make a point of visiting this stand, as on it will be found three of Vincent's improved horseboxes

mounted on a new Delaltaye chassis known as the model 83/59. The boxes exhibited have the panelled exteriors which give them such an attractive appearance. This type of horsebox both loads and off-loads from the side. The interior has received every consideration, so that it is impossible for horses to be injured during transit, Sanitation has also received great attention.

The side which drops to forth a ramp is equipped with a patented balance gear, which does away with the old

hand winch and pulley tackle. All the partitions are de tachable, so that the box can be used for other purposes.

GENERAL MOTORS, LTD. • Stand 165

• The six vehicles staged by this company form a most .representative collection. One of the most interesting is the Curtis single horsebox on the 20-25-cwt. chassis: The side and rear ramps of this have winding drums, and are easily operable by a woman. A full-length door leads into the horse's compartment from the cab. The body is thoroughly well padded, and the design well thought out.

Next there is a farmer's and livestock wagon with ex

tension racks tor tne sides, and a towing extension_ for tee tailboard, which can be used as a ramp. Side racks can also be fitted into the floor, and stand away from the body at an angle for carting hay. Then there are a milk float, a market gardener's lorry, a tipping lorry and a 14-seater omnibus with folding front.door. and an emergency door. All these four vehicles are on the 20-25-cwt. chassis.

ALBION MOTOR CAR CO., LTD. Stand 166.

An overtype bus to aecommoiata :32 passengers and general-purpose estate and prize-stock wagon form the Albion exhibits.

There is little doubt that this type of bus is one of the

most popular. The chassis employed is the 30-60 h.p. low-load-line type with a wheelbase of 1.6 ft. -3 ins., and it is interesting to note that front-wheel brakes are provided. The show vehicle. is of the front-entrance type, with

the upholstery carried out. in red antique leather. The driver is accommodated in a cab mounted at the off side of the engine and completely isolated from the passengers. The spare wheel is carried under the body at the rear, a 'special frame permitting this to be done without unduly reducing the ground clearance. The exterior is finished in natural wood, stained and varnished, and ample ventilation -is ensured by drop windows and threelarge Muirhead ventilators in the roof.

The chassis of the estate wagon is a 24 h.p. 2-tonner oil pneumatic tyres. The body is a plain platform with 2 ft. hinged and detachable sides to which slatted extensions 3 ft. high can be fitted when desired. When they are not in use, a detachable folding extension is attached to the tailboard, and this can be folded down to form a ramp for loading cattle, a pair of skids being carried to support this ramp Light side pieces can also be fitted.

GUY MOTORS, LTD. Stand 167 We believe that this is the first Royal Show at which rigid-frame six-wheeled vehicles have been shown, and one of these is the subsidy-type Guy with an open body.

One of the most attractive vehicles is the new type 20seater all-weather coach known as the Speed model. This coach has a V-screen, well raked, a bonnet which merges into the dash and deep side panels, and the whole effect one can almost term as being "racy."

The other passenger vehicle is a 30-seater double-entrance bus on the standard 30 h.p. chassis with dropped frame.

Passengers of a different class are accommodated the•horsebox built by Vineents, of Reading, this also being

mounted on the dropped-frame chassis.

The smallest vehicle is a 1-ton van with an 18 h.p. engine and bevel drive. Then there is an interesting 30-cwt. lorry with a special body having two decks and a cable and pulley gear for lowering the upper one. This vehicle will carry 30 sheep or pigs or two head of cattle.

FIAT (ENGLAND), LTD. Stand 168

Many visitors are hereafforded their first opportunity for examining the latest S.P.A. chassis, which are equipped, in one case, with a 24-seater one-man-operated bus body and, in the 'other, with a 5-ton platform lorry body.

''.Vhe other three vehicles are all of Eiat make, comprising a 502 F. 15-cwt. Windoor borsian, a 505 F. 25-cwt drop-sided lorrY, and the603 platform lorry to carry 2 tons.

The S.P.A. model 30 chassis is constructed to carry a useful load of

3 tons. Engine, clutch and gearbox form a unit, threepoint mounted on flexible supports. It has a multiple disc clutch, four-speed gearbox, two-piece cardan shaft with fabric couplings, having ball-and-socket centralizers, and a double-reduction axle of the spiral-bevel and spur type.

The model 31, although of heavier constractioin, is practically of the same specification and, like the lighter model, has a transmission brake mounted close in front of the back axle.

THE ASSOCIATED DAIMLER CO., LTD. Stand 169

. Three fine vehicles are to be found on the Associated Daimler stand. There are two goads .vehicles, one the model 418 3-ton with general-purpose body, and the other a.model 506 lorry to carry 4-5 tons. The third vehicle is a singledeck bus, the chassis being the model 416. The•model 1118 chassis has been designed of ample length to avoid tiering goods, whilst the engine is powerful. enough • to allow it to"maintain a good average speed on hills, it is of 35-40 h.p., with pump and trough lubrication. The clutch is an inverted cone driving through flexible fabric couplings to a four-speed gearbox; final drive is bV.overhead worm. The heavier goods -vehicle, model 506, has an engine developing 45 b.h.p. at;1,000 r.p.m. The -clutch and gearbox are as in the lighter model and, here again, final drive is by overhead worm. . . . The model 41.6a passenger chassis has been. designed in accordance. with the new regulations of the Ministry of Transport. The driver is seated beside the engine,permit • .ting, mityirdum.' loading space, and the engine develops 45 b.h.p, at 1,500 r.p.m. Final drive, in this instance, is by underneath worm. The springing is excellent.

DENNIS BROS., LTD. Stand 170 Appliances for fighting fires, passenget vehicles and goods vehicles Are all represented on this stand.

The largest bus is the F-type single-decker, which is a 20-seater with a double row of seats on the off side and a single row at the near side, but behind these are two longitudinal Seats, each for two persons, facing a central table, whilst at the back are four seats facing forward. Front and rear entrances are provided, and each has a drop window, in addition to two drop windows at the near side and three drop and one sliding on the off side.

The other bus is a 20-seater saloon of all-metal construction on the 30-cwt. pneumatic-tyred chassis.. The total weight of this vehicle, with an engine developing 36. b.h.p., four-speed gearbox and worm drive, is under 2 tons •, therefore it will be permitted to run, at a speed of 20 m.p.h.

The remaining passenger vehicle is a 25-30-seater coach on the F-type low-load-line chassis with servo-operated fourwheel brakes.

The smaller goods vehicle is a 30-cwt. boxvan, which is a repeat ordeii from Messrs. Hartley. The other is a 4-ton platform lorry with four-speed gearbox and worm drive. This is one of 20 Dennis vehicles ordered by Schweppes, Ltd. •

There are two fire-engines, one being a light estate type with a single-cylindered engine which can be conveniently lifted into any desired -position or equipped with a two-wheeled axle. It delivers SO gallons per minute at 80 lb. pressure. The other is a 250-gallon model with the Dennis

patent turbine Pump.

MORRIS COMMERCIAL CARS, LTD. Stand 172

The Morris-Commercial exhibit is, as is to be expected, of a most comprehensive nature. It includes a 2-ton rigidframe six-wheeler of a type well known to our readers, a fireengine of 16-36 h.p., having a 250-gallon Gwynne pump and accommodation for 10, firemen, a particularly interesting cattle truck ; a 30-cwt. tipping lorry, and a farmer's generalpurpose -utility vehicle, this.havinehigh sides carrying a tilt corer, folding steps at the rear and a tailboard which is made in three pieges, the centre portion being hinged to open as a door; two sets of seats and cushions are provided for

placing longitudinally. . . .

The shooting .brake is mahogany panelled and has fixed side .windoWs, aecOmmodation being provided for 12 person's.

There are also a milk float and a Curtis special horsebox to carry one animal. This is of a type which was fully described in The Commercial Motor a few months ago, WILLYS-OVERLAND CROSSLEY, LTD. Stand 173 The 10-cwt. and 25-cwt. Overland chassis are both to be found on this stand. The smaller model is equipped as a complete delivery van, painted grey and varnished, whilst the 25-cwt. chassis is shown with several different types of body, which should prove of interest to agriculturists. There is an agricultural wagon of the usual type with extension sides, a particularly nice-looking dairy wagon finished in cream and a standard type of lorry with tilt cover, this, like the van, being finished in grey.

LEYLAND MOTORS, LTD. Stand 174 This well-known company is represented this year by a 50-cwt. high-speed goods vehicle with pneumatic tyres, a "Long Lion" bus and a portable fire pump.

The terry has been specially designed to meet the present demand for rapid delivery combined with efficiency and economy. The engine employed is the 30 h.p. side-valve model, and the drive is taken through a four-speed gearbox and the famous Leyland torque tube arrangement with spherical thrust to an overhead worm-driven rear axle.

The .bus is similar to the standard Lion type except for a longer wheelbase, which provides. increased passenger accommodation. The power unit is rated at 28.9 h.p. and has overhead valves operated by push rods. Aluminium split-skirt pistons of a. special type are employed and these enable high speeds to be attained without risk. The actual b.h.p. developed at 1,800 r.p.m. is 58. The chassis is of the low load-line type and safety is ensured by servo-operated four-wheel brakes. With its progressive-action springs and pneumatic tyres, this vehicle provides an excellent degree of comfort for its 35-36 passengers. In fact, this model bids fair to be one of the most popular.

The fire pump is a small but portable unit which, for towing purposes, can be mounted on a two-wheeled carrier fitted with pneumatic tyres. It has a Rees-Roturbo twostage turbine pump• driven by an 8 h.p. V-twin air-cooled engine. It has a suction lift of 5 ft. and can deliver 110 gallons per minute at 70 lb. pressure, or 75 gallons per minute at 100 lb. pressure, although these figures are always exceeded.

HARRIS AND HASELL, LTD. Stand 175 Conspicuously placed at the front of this stand is a Roo chassis equipped with Hammond's patent motor horsebox. This is a type which, has obviously been designed with an excellent knowledge of the subject. Both sides let down to form ramps, and they are equipped with balance springs no that it is an easy matter to raise or lower them. Accommodation is srovided at the back for two grooms. The rear door is so arranged that as it opens it lowers the step and as it closes the step is folded up.

Other exhibits include a 24-26-seater Reo Pullman bus with a folding side door and an emergency door at the rear, the seating being on the semi-bucket principle. Thp seat in front of the emergency door hinges over to form a step. The seats have spring backs, and the coachwork, which is of Eaton construction, is excellently carried out.

The 18-20-seater coach has doors to each row of seats. with the exception of the penultimate row, access to which is gained by a gangway through one row of seats. Weather protection is afforded by a hood and rigid side curtains. We 5aoted that this model is finished in cellulose paint

Last but not least is a farmer's wagon with slatted extenaion to the sides and a folding extension to the tailboard, which forms a ramp when down.

FODLNS, LTD. Stand 176 Visitors to the Peden stand will no doubt observe with _interest the very neat way in which the overtype steam wagon has been equipped with a windscreen „having two top-hinged adjustable panels, which provide ample ventilation in good weather. The sides of the screen are carried well round, thus keeping off rain which tends to beat in when the wind is in certain directions. The screen is car' vied practically behind the motion, thus giving much better vision • than would have been the case if it had been carried far forward. So far as we remember, this is the first time we have seen such screens applied to the overtype wagon. We noticed that it is provided on the wagon boils for a haulage contractor of Cardiff. This vehicle has wheels with discs, which appears to be becoming a favourite practice, particularly in the case of tipping. wagons.

The iroden now has a brake drum on the axle and On the differential casing to comply with the later. regulations. There are, of course, also brakes in the rear-wheel drums.

Splash guards prevent mud from being thrown inwards from the rear wheels on to the chain.

Another Poden exhibit is a miller's wagon, this having Y-spoked wheels, which are interesting in that they embody an improved design in which the arms of the Y's are curved, thus preventing any risk of cracking due to internal stressing after the cast wheels are cooled off. This wagon is also equipped with a screen similar to -that described. The unladen weight is 6 ton 10 cwt. Both machines, of course, embody Ackerman steering.

THE SENTINEL WAGGON WORKS, LTD. Stand 177 Here we came across something of unusual interest in the form of an entirely new Sentinel product, this being a new colonial tractor known as the Rhinoceros, and carrying a bronze replica of that pachyderm at the front. We believe that this tractor will receive a very favourable reception. It is an extraordinary machine capable of ploughing one acre per hour. The engine and boiler closely resemble those used on the Super-Sentinel, but the engine is larger, developing 100 h.p., and the boiler is naturally of greater capacity to meet the needs of the bigger unit. The funnel also is of oval section with its greatest width crosswise, the boiler being, of course, vertical. The engine is carried longitudinally above the front of the machine with its cylinders pointing forwards. It drives by an enclosed chain to a gearbox containing pinions providing two speeds and a differential gear, the final drive being by two well-protected chains. •

The rear wheels are 6 ft. 6 ins, in diameter, and in each the rim is formed in two sections joined by strakes, thus avoiding packing of the soil and freeing any earth lifted by the wheels. Close inside the near-side rear wheel is a powerful winding drum, and rollers for conducting the rope from this' are carried on stout brackets fore and aft. To use this drum, the driving pins are removed from the near-side wheel.

A lever is provided for locking the differential gear in case of possible wheel slip. A large belt pulley is mounted on the near-side end of the crankshaft.

Somewhat unusual is the construction followed in the case of the front axle, which is centrally pivoted, provided with a laminated cross-spring, and has its ends carried between massive horn plates on the chassis, renewable slipper nlates being fitted. The frame of this tractor is built up of plates, and the ;rent and rear tanks are integral with this frame.

A Powerful screw brake operates shoes on the insides of the rear-wheel rims.

The enladeu weight of the machine is 9 tons.

Unfortunately, we cannot give very much space to the remainder of the exhibits, interesting as they are. There is, of course, the Super-Sentinel lorry, which embodies sncla ecpular features tee grease-gun lubrication, worm-and-nut Ackerman steering, direct chain drive, and an enclosed engine with a differential in the crankcase. The engine is a 60 b.h.p. and has two R.P. cylinders with poppet valves actuated by long tappets. The firebox contains three spiral banks of steeply inclined tubes expanded into spiral grooves. Stoking is from the top, the tubes forming a natural chute.

The other wagon is a three-way tipper, which can discharge its load and resume its running position in three minutes. The water for the hydraulic gear is obtained from au injector.

There is another. tractor with quite a sporting appearmice. It has small rubber tyres and is designed to haul heavy loads at maximum speeds. We noted that its windscreen has ventilation and cooling louvres at the inner ends of the V: this should avoid any risk of the glass cracking, which sometimes &emirs at this point

there is the 'Super-Sentinel double-geared tractor for rough timber and agricultural work. • 'OLIN FOWLER AND CO. (LEEDS), LTD. Stand 186 Several improvements have been incorporated in the Fowler 6-7-ton three-way tipping wagon, which is one of the exhibits. The patented boiler is of the vertical fire-tube type, entirely stayless, and it has an exceptionally large beating surface. The engine is a compound V type, the cylinder heads coming just under the seats for the driver and second man. The gearbox affords three speeds and the gears can be changed without arresting the vehicle. Final drive is by overhead worm.

As compared with early models, the crankshaft has a double-length hearing to avoid any possibility of whip, and the design is such that it is merely necessary to remove the bottom plate to inspect the big-ends and to disturb one joint to lower the motion. The loading height of the body has also been reduced by 4 ins.

A very fine example of the Fowler petrol [daunting locomotive with 40 h.p. engine is shown. It has winding bollards at the front end ; the reverse and forward gears ere operated by the same lever. This model is for Courtalds, of Wolverhampton.

Other Fowler products shown are the Diesel motor cableploughing engine, which replaces the petrol-engined machine. Consumptions of from .45 lb. to .50 lb. per b.h.p.-hour have been obtained, so that, apart from the lower cost of fuel, the economy in quantity, as compared with petrol, is over 80 per cent. The engine will start from dead cold and any number of cylinders can be cut out for running light. A compound steam-ploughing engine, class D.B., an 8-ton compound steam road roller, and an 8-ton motor road roller complete the exhibit.

CLAYTON WAGONS, LTD. Stand 188

The Clayton 6-ton steam wagon is claimed to be one of the simplest of its type on the road. Piston valves are employed instead of the usual poppet valves, and there is DO danger of these sticking. In addition, the patented control gear allows the steam cut-off to be adjusted from one-quarter to three-quarters of the stroke, thus permitting the wagon to run most economically. The engine is totally enclosed and

runs in an oil-bath, and the removal of a large inspection door fitted to the crankcase exposes the whole of the -main bearings, crankshaft and motion.

The overtype wagon is also on view. This is what may be termed a general-purpose type with three-speed gear, Ackerman steering and an improved boiler with a patented stayless firebox crown of curved construction. The crankshaft runs in ball and roller bearings, and similar bearings are used for the front wheels instead of the usual bushes. Two semi-elliptic springs are employed for the front axle instead of one, as on some of the older-type' machines.

Each rear wheel Las two sets of brake shoes.

MARTIN'S CULTIVATOR CO., LTD. Stand 191 The only exhibit of interest to us on this stand is the Martin trailer fire pump, which embodies the positive-action valveless rotary pump which is also employed on the larger Martin fire-engine. This pump is particularly efficient. It affords a good suction lift and is so simple iu construction that there are but few parts to wear.

ROBEY AND CO., LTD. Stand 192

The latest pattern Robey patent roller to be found here is known as the Clear Side Tandem. It weighs approximately 3 tons in working order and possesses many distinctive features. It should appeal strongly to users requiring a light machine for .footpath making and road maintenance, as it solves the problem of rolling right up to the edge of a kerb, telegraph pole or other object, whilst, thanks to its tandem principle, it does away with the gap which occurs between the two rear rolls of a three-roll machine.

The second Robey roller on this stand is a tandem steam pattern with instantaneous reverse. It has a low centre of gravity and is free from staggering. This actual model weighs 7 tons in working order.

The Robey 6-ton tipping steam wagon embodies many new features as compared with some older types. One advantage of this design is that the view of the driver is unimpeded.

D34 J. AND H. MeLAREN, LTD. Stand 197 Diesel engines are apparently coming into their own in this country, at least for heavy work, and one of this type is to be found on the latest McLaren motor windlass laf the type used in pairs for ploughing on the double-engine cable principle. The unit is known as the McLaren-Benz, being built under licence from the German patentees.

It develops between 60 b.h.p. and 70 bhp. The windlass hat a steel winding drum with an efficient coiling gear and 450 yds. of steel rope.

Finally, there is a 10-ton road roller, also equipped with the McLaremBenz Diesel engine, but, in this case, a smaller pattern of 30-35 bhp. Phi si roller has two road speeds, a winding drum and rope and renewable rims to all rolls.

INTERNATIONAL HARVESTER CO., OF GT.

BRITAIN, LTD. Stand 198

An industrial tractor which is becoming increasingly popular for heavy-duty Work and is being adopted Yry the Territorial Association is the International, which is -equipPed with 'duel wheels of the Muir-Hill type with sprung spuds which, When nod required for service, are carried circumferentially In the space between the twin tyres. This tractor is shoWn in several forms, of which the most interesting is -a special crane with a slewing; jib, which is described elsewhere in this issue.

There is also-a tractor with a double winch at the forward end 'for the haulage of timber out of woods.

One tractor is shown with an Eagle 6-ton trailer, the hydnaulit tipping gear of which is connected to a pump on the tractor.

Another is secured to a 6-ton Dyson trailer. This model has a wide cab affording excellent protection.

WM. FOSTER AND CO., LTD. Stand 199 Only one engine is shown here. It Is a 5 n.h.p. compound, general-purpose traction engine. The cylinders are steam-jacketed and the steam chest is so arranged that both the slide valve and the throttle valve can be examined while steam is up. A Pickering-type governor is employed.

ALFRED DUGDALE, LTD. Stand 200 Well known as concessionnaire for special equipment for the Fordson and the Ford, this exhibitor displays a Fordson tractor with a special mowing attachment having a 5-ft. cutter bar. There are golf-course wheels iman4factured by the Dunlop Rubber Co., Ltd., also for use with the Fordson tractor), these wheels being 14 ins. wide for the front and 20 ins, wide for the rear.

By the addition of the Ruckstell axle, which is shown detached, the range of the Ford gears is doubled, as the axle itself incorporates a second reduction.

R. A, LISTER AND CO., LTD. Stand 201 The Lister Auto-Truck, which will be found here, was described in detail by us in our issue for last week. It has been designed to meet the demand for a compact Mobile truck which will be cheap in first cost and in maintenance. It has been claimed that the running costs and maintenance are actually -less than id. per ton-mile, as there are so few wearing parts.

The motive unit is an air-cooled petrol elig,ine, SO: mounted in a carrier, together with the wheel, that it can be turned right round in the chassis and so permit reversing without a reversing gear. It can be run at 7-S m.p.h. fully loaded and can climb a maximum gradient of 1 in 14.

MANN'S PATENT STEAM CART AND WAGGON CO., LTD. Stand 204 We are glad to find that our old friend, the Mann 6-ton Steam wagon, is being exhibited. The particular example shown has a tipping body with hydraulic gear instead of the mechanical rack and pinion gear with which we have been familiar in the past. The chassis portion of the machine is standard and retains the well-known features of side-fired loco-type boiler, upon which is mounted a compound engine. Transmission is on the four shaft principle, being effected by spur gearing from the engine to the third shaft, whilst a roller chain completes the drive to the differential gear on the main axle.

The usual double-cross spring is fitted at the front, the axle itself being centrally pivoted, whilst the steering is effected through a gear comPrising first, a set of bevels mid, then, a worm and sector. SSOC ATED MANUFACTURERS. CO. (LONDON),

LTD. Stand 20

Examples of the Case 12-20 h.p. model have been at work in this country for years and, according to the records of the concessionnaires, the average cost of replacement parts on this model has been less than £1 per annum per tractor.

The model shown will certainly enable visitors to note the sturdy build. It.has a maximum b.h.p. of 25 and a maximum drawbar h.p. of 17 at 2.2 m.p.h. The engine has four cylinders of ft-in, bore and 5-in, stroke cast en bloc, but mounted crosswise. The cylinder, barrels are renewable, and the valves are all located in the heads. The oil is forced-fed to all the important bearings. There is a water air cleaner and the carburetter is designed to use petrol for starting and paraffin after the engine is hot A belt pulley is mounted on the crankshaft, and the clutch is a twin disc easily adjustable by the fingers.

A recent addition is a neat power take-off, with dog clutch, for driving mowers, hinders, etc., a drawing of this is reproduced on another page. RANSOMES, SIMS AND JEFFERIES, LTD. Stand 221

A.6 rt.h.p. compound steam road locomotive with a 4. .n.p. light compound steam tractor on steel tyres constitute the exhibit of this company.

The latter has outside steam chests which allow for easy access to the slide valves, and a by-pass valve permits H.P. steam to be admitted to the L.P. cylinder and so provides extra power for emergencies and for facilitating starting.

The equipment includes a winding drum and 50 yds. of steel wire rope. Long gun-metal bearings are employed for the crankshaft, which is machined from a solid forging' of mild steel mid is perfectly balanced, In the case of the road locomotive, the driving wheels are of large diameter and exceptional strength. They are shod with the usual steel cross-plates and riveted by hydraulic means. Powerful brakes are applied direct to both driving wheels.

YORKSHIRE PATENT STEAM WAGON CO. Stand 223 Here there are two examples of the W.G. model Yorkshire steam wagon, which-is one of the most recent designs anti which gave very satisfactory results durijag a consumption test -which we carried out on it some months ago.

The boiler is a double-ended loon-type set across the front. The engine is a two-cylindered vertical with piston valves and Joy valve gear. The oil is circulated by pump and the connecting-rod dippers do not come into contact with the main body of oil, but dip into troughs, so any water which may make its way into the crankcase has far more chance of separating out than in the older systems. The engine drives through to a jackshaft containing the differential gearing. The final drive is by double chains. Adequate attention has been paid to braking.

A new feature of one of the vehicles is a neat power takeoff for the tipping gear, this being mounted at the rear end cf the crankshaft, the chain wheel for operating the gear being brought into action by a sliding dog clutch.

BARFORD AND PERKINS, LTD. Stand 228

Although Barford and Perkins, Ltd., makes a large variety of motor rollers, only two specimens arc exhibited, these being the T.H. three-roll pattern and the 30-cwt. A type, also with three rolls. The latter is the smallest model made, and is specially designed*for footpath construction, asphalt, etc., but in cases where the appliance is required to do road patching in addition to footpath work, the weight is increased from 30 cwt. to 2i tons, although the rolling width of 4 ft. is unaltered. This

three roil type is useful for rolling close up with obstructions at either side. The power unit is a four-cylindered petrol engine of 11'b.h.p. equipped with governor, and the gearbox gives rolling speeds of 2 m.p.h. and 4 m.p.h.

The T.H. type has provision for water ballast. It weighs empty 8 tong, or with ballast 10 tons. The equipment includes a 120-gallon sprinkling tank with sprinklers to both back and front rolls. There are three speeds both in tht forward and reverse directions.

CHAS. BURRELL AND SONS, LTD. • Stand 232 Here is to he found a 6-ton steam wagon with Ackerman steering, loco-type boiler with Belpaire firebox and compound engine, which, by means of a special valve, can be converted to dobble H.P. as desired. The gearing affords three speeds, and the drive is conveyed by a single chain to a chainwheel on the back axle, having in its centre an enclosed differential gear. The actual model shown has a three-way tipping body, the gear being of the hydraulic type operated from the boiler feed pump. The valve gear on the engine is of the flat D pattern arranged in conjunction with Stephenson link motion.

The cast-steel wheels are cased in with light steel covers to prevent small stones lodging in and perhaps interfering with the brake.

Laminated springs are fitted at each end, that at the front being of the crass type, thus giving three-point mounting. There are three brakes, one on the flywheel, one on the backaxle drum, and the other expanding in the rear-wheel drums. The working pressure is 220 lb., and the tank capacity 220 gallons.

RICHARD GARRETT AND SONS, LTD. Stand 233 Only one exhibit which comes within our province is shown by this company ; but it is a most presentable example of the Garrett undertype steam wagon built to carry loads up to 8 tons. It is of standard construction, features of design being the inspection door let into the front of the boiler shell

to permit cleaning and examining the tubes, a two-speed gearbox, roller bearings to all road wheels, the crankshaft and countershaft, and final drive by two chains.

The body is a 17-ft, fiat platform with chock rails.

MASSEY-HARRIS, LTD. Stand 224 One of the most popular agricultural tractors is the Wallis, which is now sold by this exhibitor. It is the product of the J. I. Case :Plough Works, and is a type which is well known in England.

What may be termed the main frame of the Wallis also constitutes the engine sump, lower half of the gearbox and casing for the final-drive gearing. It is made of A-in, boiler plate. The four cylinders are cast in one with the upper half of the crankcase and have renewable sleeves. Ignition is by Bosch magneto, and a Pickering governor is fitted. The two speeds give 21 m.p.h. and .1i• m.p.h.

FAIRBANKS, MORSE AND CO., LTD. • Stand 238 The Twin City is a simple and efficient tractor with a four-eylindered monobloe engine with the cylinders east with the upper half of the crankcase. It has 16 valves, all being in the head, which is removable. The cylinders themselves are renewable individually. • Counter-balancing is employed for the crankshaft, and we noted that the big-end bearings have four bolts each. A governor and an air cleaner are included. A twin disc clutch conveys the drive to a bevel-driven cross-shaft, at one end of which is a belt pulley. The frame is composed of two semisteel castings securely bolted together and forming a very strong backbone.

MARSHALL, SONS AND CO., LTD. Stand 240 There are two steam rollers and a 7 n.h.p. single-. eylindered steam traction engine amongst the exhibits on this stand.

The Marshall-Universal of 8 tons nominal weight has been designed to meet modern needs, and is claimed to combine the operating advantages of the standard three-roll and tandem types. Its cylindrical rolls are adjustable to any required road camber by means of positive and automatic locking devices. The main axle is made in two parts, each supported on horizontal trunnions and each is positively adjustable to any degree of camber, the graduated indicator showing the level and cambers of 1 in 96, 1 in 48, 1 in 32 and 1 in 24. The front rolls will lock in the horizontal position for flat surfacing. The engine is of the quickreversing type.

In the standard roller, a piston valve supersedes the usual D-type valve, and a 'simplified radial-type link motion with only one sheave. strati and rod replaces the Stephenson type. The traction engine is suitable for 'travelling speeds of 2 m.p.h. and 4 mph. It has four-shaft transmission and Stephenson link motion.

AVELINO AND PORTER, LTD. Stand 24t Road engineers will find here some interesting rollers. one, the U-type, is driven by a crude oil engine and weighs. 6 tons empty. The engine is a single-eylimfered four-stroke of the horizontal type. It is claimed that this is particularly accessible, involves less wear and tear on the connecting rod bearings and crankshaft journals, and the piston is thoroughly lubricated where its pressure is greatest, i.e., along the bottom of the cylinder. The type F compound steam roller weighs. 121 tons empty, and has a boiler of the Belpaire type, and the cylinder has piston valves instead of the usual fiat slide valves. The equipment includes a Price resilient scarifier of the three-tine size and with a shock-absorbing device.

The other roller is the type D compound of 8 tons nominal weight.

Finally, there is a compound steam tractor, type M W. GOODYEAR AND SONS, LTD. Stand 279 Greenbat battery electric trucks built by Greenwood and Batley, Ltd., of Leeds, are to be found on this stand, together with a special trailer for use with them.

The motors are a special traction type and the controller and steering handles are arranged for driving in either direction. There is a pedal which must be depressed to close the electric circuit, and this same action releases the brake. The pedal is interlocked with the controller, and the latter must be brought to the neutral position before the truck can be started.

The trucks are of all-steel construction, Well sprung and built to withstand rough treatment.

MERRYWEATHER AND SONS, LTD. Stand 323 As is usual in the ease of the Royal Show, this wellknown company of fire engineers is responsible for the safety of the show in respect of fire.

The equipment of the stand is most complete. It includes a ETatfield fire-engine similar to that supplied to fire brigades in all parts of the worm, also several Hatfield trailer pumps of various sizes capable of delivering from 150 gallons per minute up to 250 gallons per minute. Chemical and hand extinguishers include the Komis Kemik and Fire Suds patterns for combustible liquids.

HALL, LEWIS AND CO., LTD. Stand 369 A large stand, which is somewhat difficult to find without careful reference to the map of the ground as it is numbered quite differently from the surrounding stands, is occupied by this well-known and enterprising coachbuilder. It is situated in Section A, along the avenue to the right of the main entrance.

There are five different types of vehicle, all, however, of the same make, i.e., Thornycroft. The largest is a 26-seater single-deck omnibus on the S.B. chassis. There is also the Emerald 20-seater single-deck bus, an Al 20-seater bus on the 11-ft. 6-in. wheelbase chassis, a van on the well-known Thornycroft 30-cwt. subsidy-type chassis and, finally, a 3-ton K.B. model hinged-sided lorry
