Preliminary Notices of Some of the More Interesting Exhibits, Alphabetically Arranged. The Stand Nose are from the Official Plan.
Adams and Co., Newton Road, Tunbridge Wells.
123] JACKS AND LIFTERS. [123 The ingeniously designed brush which can be connected to a water supply for use when cleaning down vehicles, which will be shown in service, will naturally create much attention. Of greater interest to our mechanically-minded readers will be the Adams patent hydraulic lifting and weight-recording jack. and the Adams patent lifting and transfer jacks. The first of these appliances is already well known to us as the " jack which weighs while it lifts," descriptions of the early type of which have already appeared in the pages of this journal.
A. T. Speedometer Co., Ltd., Long Acre, London, W.C.
112] A MAGNETIC SPEEDOMETER. [112
The speedometer which is designated more generally as the A.T. is of the magnetic type. The construction of the instrument itself is characterized by considerable mechanical ingenuity. Registering up to 30 m.p.h. for the commercial type, users have stated that the instrument is extremely accurate in use. Having inspected the various types on view, the visitor should not leave this stand without noting the specal form of drive with which these appliances are fitted. It will easily be imagined that, no matter how carefully designed and built an instrument of this type may be, accurate registration is impossible unIe.s,s the drive from the shaft to the road wheels be transmitted to the instrument without outside interference. Accordingly, then, the A.T. Co. has evolved a special type of link chain drive which is strongly nrotected by an inside casing of coiled steel ribbon further protected on the outside by a brass sheathing.
T. C. Aveling and Co. (Birmingham), Ltd., New Canal Street, Birmingham.
131] A PRACTICABLE WEATHER SCREEN. [134
The great feature to be seen on this stand is, of course, the Aveling weather screen, with the construction of which many of our readers are already fairly familiar. To the newcomer and user, however, the simple ingenuity displayed in the design of this accessory cannot fail to make a very strong appeal. The advantages claimed by the maker are: complete protection for the driver in all weathers, whilst it can be instantaneously closed, thus saving delay in fixing and stowing. No glass is used in the construction of this screen ; thus fractures to glass from vibration, and accidents to the driver from the same cause, are naturally done away with. The screen is instantly adjusted to suit any driver, while quite an unimpeded view of the road is obtained without the distortion or reflection which is sometimes given by the use of the ordinary glass screen.
Brampton Bros., Ltd., Oliver Street Works, Birmingham.
115] CHAINS FOR COMMERCIAL VEHICLES,
This Midland concern has for many years specialized in the making of all kinds of block and roller chains, and its progressive policy will be strongly emphasized by the interesting range of silent chains which will be on view. Of high precision in manufacture, those Chains are particularly suited for camshaft and magneto drives, gearboxes, and also for final drives to road wheels. Examples of sprockets and chain pinions of various pitches will also be shown on this stand.
E14 David Brown and Son (Huddersfield), Ltd., Huddersfield.
148] WORid-DRIVEN BACK AXLES. [148 A worm-driven rear axle, for building into a light delivery van of a load capacity up to 10 cwt.., will arrest our attention immediately on arriving at this maker's exhibit. The casing of this axle is formed of two tapered tubular-steel castings. The worm is arranged above the wheel, so as to allow ample road clearance. The worm is hardened and ground and made of a carefully-selected high quality of steel, and this gears with a wheel composed of the toughest phosphor bronze. The differential ia of the bevel type. The gears and road wheels run on ball bearings throughout, while ball thrust bearings are provided for both worm and wheel. Great care in the design is manifest, in order to render the axle oil-tight, ensuring so far as possible the gear's working under ideal conditions. We shall next turn our attention, no doubt, to the heavier, worm-driven rear axles, of much the same construction, but suitable for loads of from two to three tons and from six to seven tons.
Brown Bros., Ltd., Great Eastern Street, London, E.G.
117] AN INTERESTING LIGHTING SET. [117 This well-known company will stage a, comprehensive array of those of its specialities which are betterknown and of great interest to users of commercial motors, chars-à.-banes, and motorbuses. One of the most important exhibits on this factor's stand will be the Brolt lighting sets, for use on motorbuses and similar vehicles. This necessitates the use of a dynamo having a large output of current, and for this purpose a new model, known as type Cl, of '200-amps. capacity, has been introduced. Other accessories shown on this maker's stand will consist of lamps for use on commercial motors, lubricants and oils, bolts, nuts, various tools, and sparking plugs, and also the well-known Raybestos brake and clutch linings. It is impossible to summarize Brown's exhibits, they are so many and so varied. This house provides everything for the motorist, in short.
S. F. Bowser and Co., 32, Victoria Street, S.W.
1331 PETROL STORAGE PLANT. [133
This company has built up an extensive business in America and many other countries, in the manufacture and supply of its petrol-storage plants. Here at Olympia we shall find an interesting exhibit, which shows very quickly the principle on which the Bowser system is worked. We shall note that wastage and loss by evaporation is reduced to a minimum, and that danger from fire is to a large extent eliminated. Further, the maker claims, with some justification in our opinion, that petrol can be kept in better condition by means of this system than is the case when such fuel is retained in tanks of the usual type.
W. Canning and Co., 133.137, Gt. Hampton Street, Birmingham.
127] PLATING OUTFITS. [127 Of particular interest, to our readers on this stand is the range of plating outfits which will be exhibited. These consist of tanks, dynamos, and other necessary appliances, together with a supply of material for plating work in general.
Carbic, Ltd., 27, Cannon Street, London, E.C.
104] THE CARBIC SYSTEM OF LIGHTING. [104 The immense increase in the number of motordriven business vehicles renders the provision of a satisfactory lighting equipment a matter of the highest importance, not only as a safeguard against accidents to persons, but as against damage to the vehicles themselves. The special feature of the Carbie system of generator construcftm lies in the use of Carbic cakes in place of the ordinary carbide of calcium. Each of these cakes is guaranteed by the maker to produce 10 cubic ft. of pure acetylene gas, and, by the construction of the generators, this gas is automatically paariuced as iequired. As soon as the lights are turned out, the gas generation ceases ; as the lamps are again lighted, the gas is again automatically generated. The generators employed are made in three sizes ; each has been adopted to suit usual needs. One has a capacityof 10 cubic ft., and it st ill run one light of 25 c.p. for 20 hours. The overall dimensions are 16 ins. by 1,0; ins., while the complete weight is 201, lb. This generator is suitable for use tat lorries and on heavy commercial motors generally.
Car Springs, Ltd.,
19, Fairfield South, Kingston-on-Thames. 031 STOCK-ABSORBING DEVICES. [93 STOCK-ABSORBING DEVICES. [93
On this stand we shall notice a series of the Acme shock-absorbing devices, having variable spring res:stance for various loads and road surfaces. These appliances are intended for use on commercial motors, buses, chars-h-bancs, fire-engines, ambulances, and other vehicles. This maker has gone deeply into the question of shock absorption, and we shall no doubt spend some few moments in listening to an interesting discourse from the maker's representative on what is required from the ideal shock absorber, and the manner in which Car Springs, Ltd., iiseets the required conditions.
William E. Cary, Ltd., Redbank Spring Works, Manchester.
OPEN PLATE SPRINGS. [128 It is a noticeable mark of the advance of any industry when makers of reputation are found to be specializing in the production of some particular component largely used in that particular trade. William E. Cary, Ltd., we shall note, has staged a very fine array of vehicle springs of the registered open-plate tape. We shall also find that the great experience in the construction of these articles by William E. Cary, Ltd., has been brought to bear in the design of these productions, and if during our visit we have time For
few words on the subject of spring construction, the (a'ary representative will no doubt give us much taluable information as to the why and wherefore of spring construction and design.
R. W. Coan, 219, Goswell Road, Clerkenwell, E.G.
100] ALUMINIUM SPECIALISTS. [100
There are few foundries in this country where a greater range of aluminium castings, for use on motor vehicles, is turned out than in that owned by Mr. IL W. Coen. Starting something like 20 years ago, when aluminium was approximately £1000 per tan, and when a. very small staff was employed, this maker has built up a large and rapidly-expanding bueetess. Crankcases and gearboxes, radiator fittings, and similar components form the major portion of the Coan business. A considerable amount of work is dune, however, in the repairing of cracked and fsaetared parts in brass, aluminium, steel, cast ifon, anti other metals. G. A. Claus,
150, Great Poriland Street, W.
111] [111 lip to the moment of going to press we have beea unable to obtain particulars of the exhibits for this stand.
Coventry Chain Co., Ltd., SPon End Works, Coventry.
121] Au, ABOUT SILENT CHAINS. [121 Visitors who are interested in any way in chains for commercial motors, cannot fail to be already fairly familiar with the products of this well-known company. The most popular model of Coventry adesign, intended for use. on heavy vehicles, and which is, incidentally, the one in most demand, is the special commercial-motor chain No. 135. A few minutes spent in examining the construction of this chain will be time well spent. We shall be able to realize to some little extent the great care necessary in the design and manufacture of such power-transmitting devices. The links, of substantial design, strong but having weight eliminated wherever possible without sacrifice of strength, the pins and rollers machined to the micrometer, and the great care spent in assembling these chains, will leave a most favourable impression on the minds of visitors.
Davenport and Co., Ltd., 1131-105, Clerkenwell Road, E.O.
103] ACCESSORIES OF ALL KINDS. [103 WC, shall discover on this company's stand a comprehensive aeries of accessories, all of which find a place by reason of their general utility, either in the modern garage, or in the toolbox of the commercial motor. Mileage recordeas with cardan shaft or scroll drive, axle odometers for hire work, lamps and horns, tire levers, sparking plugs, accumulators, garage clocks, and clocks for delivery vans, and a largo array of other fittings and accessories of the same type will cause the visitor to linger for a few moments.
Dover, Ltd., Northampton.
140] STEERING WHEELS AND OTHER COMPONENTS. [149
This company has specialized for many years in the manufacture of Exonite steering whete:e. The rough usage to which the steering gear of many commercial motors is subjected makes the majority of these component parts liable both to fracture and to loss of gripping surface. A slight miscalculation or slip of the driver's hand in negotiating a difficult corner in thick traffic may easily lead to a nasty and expensive accident. It is the claim af. Dover. Ltd., that the materials used in the yeas traction of its steering wheels renders such a happening extremely unlikely.
Drummond Bros., Ltd., Guildford.
135] MACHINE TOOLS OF ALL RINDS. [135 One of the few expenses which the user of the modern 'commercial motor cannot estimate is that which sometimes occurs for small renewals and repairs. The seized piston, the badly-worn big-end, the drilling of a half-inch hole, the maltes of an unusual size or bolt-all these/may arise, anti they may take place any day, or they may not happen throughout years of use of a commercial motor. Done by the driver of the machine in his own little workshop, the cost of such a repair is but a few pence, and the machine is not held up for any lengthy period. Exe tatted outside, however, several profits have to be made from the work. Owing to pressure of other orders, the repairer ne. k not be able to do the few minutes work required or anything from half a day to a week's time. Druinmond Bros., Ltd.. has built a series of small-power foot and hand driven machine tools, which are designed to enable the driver or the shop mechanic to effect most small repairs at his own time and convenience.
Electric and Ordnance Accessories Co., Ltd., Birmingham.
114] TERUST AND LOAD ROLLER BEARINGS. [121
A big range of the Timken roller bearings and co,mponent parts is shown on this maker's stand. Of great interest to our readers will be the new design of bearing suitable for the front hubs of commercial vehicles, which is intended for centrally-pivoted steering, and of such a design, that steering strains are not communicated to the steering wheels. A detachable front hub, suitable for commercial motors, and mounted on Timken adjustable roller bearings, will also be seen, while other exhibits of interest will consist of the rear wheel from a heavy motor vehicle, arranged so as to demonstrate the successful fitting of a Timken adjustable roller bearing to this class of wheel. A Vickers front axle, suitable for a 25-cwt. or 30-cwt. van, and a series of universal joints, fitted with Timken roller bearings, will complete the component parts placed on view by this company.
B. M. Fair and Co., 3, Gt. Winchester Street, London, E.G.
144] TITE Mi. MAGNETO. [144
On this company's stand we shall take the opportunity carefully to examine the range of magnetos now so well known by the name of Mea, or the magneto with the bell-shaped magnet. Several advantages are claimed for this form of construction by the makers—chiefly accessibility and a hotter spark on retardation. An interesting feature is the small window, through which the timing of the spark can easily be seen by means of bold figures. This enables the driver, who is not exactly an expert on ignition, to effect his own adjustments without having to lay up the vehicle in the hands of the maker. The two winning Peugeot's in the Grand Prix race used these magnetos.
Fastnut, Ltd.,
115, Newgate Street, E.G.
96] SPANNERS, WASHERS, WRENCHES, ETC. [96
The specialities made by Fastnut, Ltd., will not be unfamiliar to many of our readers, who will no doubt take interest once again in examining the many ingenious, labour-saving devices incorporated in this company's patent appliances. The Fastnut washer, spanner, wrenches and file handles will all be shown in many sizes, and the few of our readers to whom these fittings are not known will do well to take an opportunity of testing the Fastnut specialities.
Hoffmann Manufacturing Co., Ltd., Chelmsford.
141] HIGHLY-ACCURATE BALL BEARINGS. [141
Here an interesting exhibit of the Hoffmann Menufaeturing Co.'s products is on view. Great accuracy is a very strong point in the Hoffmann products, the balls for use in ball bearings being guaranteed to be accurate within 1-10 000th inch. Here for the first time we shall see the Hoffmann steel roller bearings, which have been manufactured and sold during the past three years. The demand for these bearings, however, has been so great, that until the recent factory extensions were got into working order, it was impossible to supply the outside public with these productions. We shall take great interest no doubt in the two bearings taken from the front wheel of a taxicab in London service. These are of the ball and roller type, and, we shall notice that they are in almost perfect condition, after running under the heavy stress of this class of work for 15,000 miles.. Our readers who are interested in the scientific side of ball and roller bearing production will notice the test apparatus, by which the starting and running friction of ball bearings, roller bearings, and plain bearings can be seen.
E18 George Fischer Steel and Iron Works, Ltd., Schaffhausen, Switzerland.
95] A MAKER OF CAST-STEEL WHEELS. [95 On this maker's stand we shall notice a series of cast-steel wheels for use on omnibuses, chars-a-bancs and commercial motors generally. The clean construction and high-quality materials used will give us an idea of this continental maker's methods, and we shall no doubt be at some little pains to compare the products with those of English makers.
Howes and Burley, Ltd., Bishop Street, Birmingham.
100] ACETYLENE LAMP OLTTFITS. [100
We shall recognize an old friend in Howes and Burley, Ltd., which company will stage a very comprehensive selection of its lamps and generators for use on commercial motors. The Howes and Burley patent No. 9249 generator will interest us for some few moments. In this appliance the spent carbide is sifted from the fresh, thus insuring regularity and economy of gas supply. Lamps can be relit immediately from a partly-used charge even if the generator has been out of use for several days. This is a feature which will no doubt appeal to many users. Simple in design, and strongly constructed, the generator is moderately priced, and is already in service by many big users. The side, tail and headlamps on exhibition are comprehensive enough in their range to insure the satisfaction of even the most. ciitical user, who can hardly fail to find a lamp suited to his particular needs. Bulb and electric horns, as well as mirrors, will complete this company's exhibits.
The Imperial Motor Industries, Ltd., 11, Denmark St., Charing Cross Rd., London, W.C. 91] AN INTERESTING RANGE OF ACCESSORIES. [91 This factor will have on view a series of the R.W.F. ball bearings, together with a range of Tangye jacks intended for use with commercial vehicles. Of more than passing interest, however, will be the Mauvillier carburetter, from which this company is expecting great results. Taking for granted that the ideal earbuaetter will give a perfect mixture of petrol, vapour and air at all s.peeds, this maker claims to obtain ideal working conditions by means of two separate jets, each of which has its own choke tube and air adjustment, and is complete in itself. The throttle closes the main jet only, the engine being started with the throttle in this position. Easy starting and smocith running are obtained by means of the pilot jet, which is always open, and which can be adjusted to give a mixture suitable for any engine. The level of the petrol in the jets is obtained by a float, which is situated concentrically with the main jet, thus ensuring that it is maintained at the same level at all times. All parts of this carburetter are easily accessible, and any one part can be detached or replaced without altering the adjustment of the other component points. The company also shows a series of the Baldur springs, which are being supplied to many of the leading commercial-motor manufacturers in Germany.
J. Liversidge and Son, Ltd.,551, Old Kent Road, S.E.
137] ACETYLENE-LIGHTING PLANT. [137
This company is represented in the tire, accessory and body-building sections. This stand, however, we shall find devoted to the staging of accessories. Here we shall discover samples of the well-known A.L. generators of two types : first, of cone construction, with carbide capacities from 1 lb. to 7 lb. ; second, generators of the disc-feed construction made from aluminium castings and with a carbide capacity of from 1 lb. to 21 lb. We shall also notice the range of lamps for use on commercial motors, illuminated signs, and complete ranges of fittings for nse in connection with acetylene lighting. We shall describe the exhibits on the remaining stands of this company under their respective stand numbers. Joseph Lucas, Ltd., Great Kin: Street, Birmingham.
1191 LAMPS OF NOTEWORTHY CONSTRUCTION. [119 In the early days of the cycling boom, there were few lamps more widely known or of such fair reputatiou as those made by Joseph Lucas, Ltd. Here, at the Commercial Motor Vehicle Exhibition, we shall have an opportunity of inspecting this maker's latest efforts in the production of suitable lamps for use on commercial motors dated 1913. An acetylene lamp which should attract our attention specifically is termed the Lorilite. The water feed on this lamp is by a simple on-and-off cock, and a steady light can be obtained for 4i hours. It has a Mangin lens mirror, and is supplied either in brass, or with a black enamel finish.
R. Melhuish and Co., Ltd., 50-51, Fetter Lane, London, E.C.
132] TOOLS FOR THE USER. [132
The tools shown on this stand will make a special appeal to the user of motorvans and steam wagons. It has ever been the Melhuish policy to carry a stock of the latest tools and labour-saving appliances garnered from all over the world which are likely to be of service to the user of power-propelled road vehicles. We can ourselves testify to their worth.
The Motor Radiator Manufacturing Co., Park Side, Coventry.
116] RADIATORS FOR COMMERCIAL PURPOSES. [116
As its name implies, we shall find on this stand a comprehensive selection of radiators both small and large. Most of these exhibits are made under the Dr. Zimmerman patents, and we shall find that they are designed for use on tractors, petrol-driven lawn mowers, motorbuses, and fire-engines. Radiators intended for use on the machines made by Jahn Fowler and Co., Ltd., Ransomes, Sims and Jefferiess, Ltd., Wolseley Tool and Motor Car Co., Ltd., Hillman Co., Tilling-Stevens, Armstrong, Whitworth and Co., Ltd., and Saunderson and Mills, Ltd., will prove to us that the products of this company are in general demand by many of the leading manufacturers in England.
Nicole, Nielsen and Co., Ltd., 14, Soho Square, W.
92] SPEEDOMETERS. [92 This company stages a selection of the Watford speedometers and revolution indicators of various types. The commercial model, No. 726, which has a 51 in. dial, is priced at three guineas. This is designed primarily for commercial and other vehicles which do not travel at high apeeds. The dial is calibrated to 30 m.p.h. The scale is plainly printed, and the indication is easily read. Fitted with a total mileage counter up to 10,000 and repeats, this model should find a ready sale. A speedometer of rather better type is known as model 300.
J. and R. Oldfield, Ltd., Refulgent Lamp Works, Warwick Street, Birmingham.
108] DEPENDENCE LAMPS. [108
The special type of " Dependence" spring-bracket tail lamp staged here has proved to be one of the most successful productions of this company. These lamps are now in use in many parts of the world, and an excellent series of testimonials has been received by the company regarding their value. The oil well, which is designed to burn paraffin, is spring mounted, a feature which renders it extremely unlikely that the flame could be shaken out, even when the lamps are in service on the roughest roads. The small extra cost of this lamp over many other types is more than repaid by its greater life and reliability. A full range of these lamps, together with other " Dependence " models will be shown in a variety of adaptations in oil, oil and electric, and oil and acetylene. Generators, headlamps, mirrors and safety lamps will also be on view.
Premier Taxameter Co., Ltd., 108, Albany Street, Regent's Park, N.W. 97] ACCURATE TIME AND MILEAGE RECORDERS. [97 The number of taximeter makers of repute may be counted on the fingers of one band. There will be few to dispute the statement that, amongst these makers, the Premier concern occupies a leading position, as its name implies. On this maker's stand will be shown a range of the latest recorders for use on taxicabs and other vehicles intended for hire purposes.
Hans Renold, Ltd., Brook Street, Manchester.
139] DRIVING CHAINS OF ALL KINDS AND SIZES. [139 In an industry such as the making of chains there is naturally little scope for striking alterations in design. Few unique innovations are possible, and, accordingly, it is difficult to select examples of noteworthy specialities on the stand of any particular chain maker of repute. The little alterations made from time to time in the design and manufacture of chains pass unnoticed even by many large users. We should be perfectly safe. in stating, however, that rarely does a year pass without several detail improvements being effected in the construction of Renold chains. From time to time we publish in this journal—under the "Patents Complete d' of manufacturing improvements which have been adopted. Bearing all this in mind, we will be interested in observing the patent-liner silent chain made by this company. There is an inner and outer combination of recesses at each joint, the liners, in one combination, moving through the clearance recess of the other sufficiently to allow the chain to encircle the smallest sprocket used. The liners being at the outer ends, the plates bear on the studs when the chain is in tension.
Ross, Courtney and Co., Ltd.,
Ashbrook Road, Upper Holloway, N. 138] GREASERS, FILTERS, PUMPS AND COCKS. [138 here we shall have an opportunity of examining a large variety of fittings of peculiar interest to users and makers of commercial motors. One of the many useful articles made by this company we shall find in the patent grease cone, which delivers a ribbon of grease into gearboxes, lubricators, stauffers, and similar fittings with the minimum of trouble. This cone can be loaded with grease in the usual way, or can be filled by means of special grease cartridges, which this company supplies. Ross-Courtney patent terminals for connecting electric cables, the patent anti-vibration greasers, aluminium petrol filter, the hand and power pumps, and taps, cocks, unions, T and Y pieces, together with many other fittings, will give us a good idea of the specialized reputation for work in which this company is so greatly inter e sted.
Rotax Motor Accessories Co., 434, Great Eastern Street, London, E.G.
129] LIGHTING OUTFITS. [129 Here we shall have an opportunity to inspect the electric-lighting system intended for service on commercial vehicles and ;'known as the Leitner. The output of the dynamo in this system is electrically controlled by a brush on the commutator in series with a, field winding. An automatic cut-out is provided, which prevents loss of current. The Rotax commercial Clarion horns, a Sampson jack with a quick release, complete tool kits for motorvan or Jerry work, oil-lamp sets, mirrors for steam wagons, and many other useful accessories, go to make up a, very comprehensive accessory exhibit. Rushmore Lamps, Ltd., 46, Brewer Street, Piccadilly Circus, W.
1051 ELECTRICAL AND ACETYLENE LIGHTING SETS. [105
A full range of Rushmiire acetylene:and electriclighting sets will be seen on this stand. It is by now rapidly becoming realized by the user that it is necessary for the accessories on a commercial motor to be of as high a grade and of as reliable a character as is the machine itself. Business vehicles are now often. called upon to ma,ke long journeys, many of which are done at night over, in many cases, badly-paved roads unfamiliar to the driver. The Rushmore selfcontained electrical set consists of a compact dynamo arranged so as to be driven of the engine, together with a small battery of accumulators and the necessary head, side and tail lamps. Possibly the acetylene lighting sets of Rushmore Lamps, Ltd., are more familiar to the majority of our readers. The generator is of the shaking grate type, and many thousaDds of users, both in England and Overseas, have testified to its general efficiency in service. The Rushmore head lamps are fitted with a special lens mirror, which was introduced by the company so long ago as 1900. This is ground to a graduated thickness, which increases towards the edges of the mirror, the result of the employment of this lens being a varying refraction, calculated so as to produce rays exactly parallel to issue from the focus. These head lamps are, made in two patterns, and we shall have an opportunity of examining both types.
S. Smith and Sons, Ltd., 9, Strand, W.C.
140] THE NEW SMITH FOUR-JET CARBURETTER [140
This umber will show a very comprehensive selection of accessories of interest to the user. Speedometers of the well-known commercial type, which are used by so many of the leading manufacturers on the wagons which they build, will be seen in force. Sparking plugs, tools, and general accessories for use on commercial motors will also be staged. The feature of outstanding interest, however, will be the new Smith four-jet carburetter, which we described at length soiree few weeks ago. This appliance is claimed by its makers to give greater engine power at all speeds, with a reduction in the amount of fuel med. Caresal examination of the working and construction of the appliance will do much to convince us that the maker's claims in this direction are based on very substantial grounds. Accessibility is a great feature of this carburetter, which will appeal, we have little doubt, to many visitors to Olympia.
Spiral Tube and Components Co., 61, Northdown Street, King's Cross, London, N.
193] RADIATOR SUPPLIES. rI43 Here we shall find staged an inter esting exhibit of cast tank radiators, spiral tubes, and other products of this well-known company. Many big users, including the War Office, the L.G.O.C., and the National Steam Car Co., are large customers of this concern. The leading product is, of course, the spiral tubing, which is sold separately or is made up into radiator centres or complete radiators. Dashes and radiators, coils of spiral tubing, and other types of radiators intended for use where vibration is great, give the visitor some little idea of the range of a,ctivity with which the Spiral Tube Co. is concerned.
R. Terrell and Co., 9, Regent Street, W.
081 COMMERCIAL-VEHICLE LAMPS. 108
First and foremost on the Terrell stand we shall take an opportunity of examining the cast aluminium generators for use with the well-known E.C.L. lamps. As to the lames themselves, we shall note that the E'20 smaller types are cast in two pieces, and are largely built up witheut the use of rivets or screws. The larger headlamps are of very much the same construction, a third piece being added, however, by the necessity of introducing adequate outlet for the heated gases at the top of the lamp. It is not without interest to note that the London General Omnibus Co., Ltd., is a large user of these lamps, as are also many of the leading motorbus and railway companies who use road vehicles. The generators are constructed on the permutable-wick principle, and the maker claims that they generate a larger percentaw of gas than does the more ordinary type. Made in various sizes and finishes, it would be difficult for the user not to select a suitable lighting set for use on motorbuses or motorvans.
Tormo Manufacturing Co., 67-68, Bunhill Row, London, E.C.
1221 RELIABLE BALL BEARINGS. [122
An imposing assortment of ball bearings of all sizes. designed for journal or thrust loads will be an attraction on this stand. This firrn are agents for the wellknown Continental firm of Messrs. Fichtel and Sachs, whose products are largely used n this country, and the exhibit will include many examples of these reliable bearings.
C. A. Vandervell and Co., Ltd., Warple Way, Acton Vale, London, W.
114] LIGHTING OUTFITS FOft MOTORVANS. [114
Bound to attract attention with an exhibit which, at first appearance, is most familiar to the majority of our readers, C. A. Vandervell and Co. will, having first drawn the visitor's notice, demonstrate the qualities of the Vandervell electric-lighting sets. A bus body, similar in outward appearance to those in the service of the London General Omnibus Co., Ltd., serves as a very attractive stage setting for this company's lighting outfit.
Henry Watson and Sons, High Bridge Works, Walker Gate, Newcastle-on Tyne.
136] CYLINDER-CASTING SPECIALISTS. [136 In the matter of automobile cylinder castings, it is, of course, essential that only the finest grade of closegrained cast-iron having good machining qualities should be used in their manufacture. MessrsWatson and Sons have specialized in this particular branch of the industry for some considerable length of time, and runny examples of cylinder, piston and crankcase castings of high-quality material will be shown. In addition to these, specimens of machined singlecylinder, twin, three and four-bore castings en bloc will be on view, showing the high quality of machine finish obtainable on this firm's special mixtures.
S. Wolf and Co., Ltd , 115, Southwark Street, London, S.E.
113] SPECIALITIES WHICH ALWAYS "CATCH ON." [113 In the space at our disposal it is impossible to mention any large number of the various accessories, all of which are of value both to the user and maker of commercial motors, exhibited on this stand. We will confine ourselves, therefore, to a short r4sume of some of the appliances staged which are of outstanding interest. First and foremost we should place the Solex carburetter, which we have already described at length in the columns of this journal. Its adoption by so many makers of vehicles is remarkable. Wolf's claim that this carburetter is unique for its constructional simplicity and its reliability under all working conditions. By reason of its design, itis economical with fuel, while automatic working gives quick engine acceleration whenever required. There is little that is likely to get out of order, even under the most severe working road conditions. The Solex, too, is an object lesson to designers. While at. this stand,
we would do well to examine the Maximall petrol motor, the Sauser sparking plugs, the Solex radiators, eminently practical units which are being increasingly embodied in British and foreign models, and the range of portable hand tools and also the ball, bearings, of which a great number is now in use.

145] A WRIGLEY-DESIGNED REAR AXLE. [145
The feature of this well-known gear manufacturer's exhibits will be a complete back-axle unit of excellent de.sign and finish. It is of the worm-driven liveaxle type, and is particularly suitable for either a two-fin Colonial chassis or would suit an omnibus cheeses, of the type which are running in the Metropolitan area at the present time. This axle will be shown in section. There will also be an example of a rear axle centre case, specially designed and constructed to the order of T. 'Tilling and Co., Ltd. A light transmission set, comprising a three-speed gearbox, worm-driven axle, and torque mechanism should prove of special interest to light delivery-van-chassis designers.
