A Report on the Road Rollers, Refuse Collectors and other Motors and Appliances which are Being Shown This Week at an Important Event in London
1.11OLLOWING immediately upon the .12 great Commercial Motor Show at Olympia, the Public Works, Roads and Transport Congress and Exhibition at the Royal Agricultural Hall, London, commenced yesterday. It is an exhibition of considerable importance to all municipal surveyors, road engineers and others interested iu public works of pvery kind, and as the congress is held every alternate year there is, of course, evidence of considerable advance in the designs of many of the appliances and vehicles that are available for examineion. Details of the motors and machinery which come within the province of this journal are given in the following pages.
JOHN ALLEN AND SONS (OXFORD), LTD. Cowley, Oxford. Stand 32 (Main Hall).
THIS old-established engineering and boiler-making concern is showing a standard 10-ton compound-engined steam roller which has been completely overhauled and modernized so as to demonstrate the company's methods and !workmanship. The Oxford-Waveless roller, in which the usual wheels are 4.eplaced by girder tracks that are equivalent in effect to a wheel 18 ft. in diameter, is also to be seen, the object of the design being to obtain a road surface evenly rolled and free from waves. The motive power is a twocylindered high-pressure steam engine. An advantage of the girder tracks is that the area of track in contact with the ground being in proportion to the hardness of the latter, the machine is suitable for rolling both soft and hard road surfaces.
AVELING AND PORTER, LTD. Rochester.
Stand 81 (Main Hall).
THE exhibits upon this stand that are of interest to users of commercial motors are three different types of load roller, two being propelled by steam power and the third by a crude-oil engine. The heavier steam roller, model AD, weighs, in working order, 111 tons and is equipped with a Price patent two-tine resilient scarifier, whilst the smaller, or 0 model, is of the tandem type intended for tar macadam and
bituminous carpet rolling. It has a rolling width of 4 ft. and weighs, in working order, 6i tons.
The machines represent a complete range of steam-operated road rollers made by this company, and it should be pointed out that the type of boiler employed has no stays in the crown, the firebox-top being corrugated to give the necessary strength. It will be seen that the transmission gearing is located between the horn plates, where it is securely supported.
The crude-oil roller, type QF, weighs 15i tons and has a slow-running, singlecylindered Diesel-type engine. ,The engine speed is approximately equal to that of a steamroller of equivalent weight, upkeep costs being correspondingly low. The crankshaft and main transmission shafts have self-aligning roller bearings.
BARFORD ANL) PERKINS, LTD. Peterborough. Stand 80 (Main Hain'.
THE motor road rollers on view on / the stand of Barford and Perkins, Ltd., are of an up-to-date type. Three entirely new models have been introduced since the previous exhibition of the Public Works, Roads and Transport Congress, these being the TJD, B and Y5 models.
The TJD model is a 131-ton threewheeler' with a 35 b.h.p. oil engine, and is similar to the T model exhibited in 1927, but it embodies a new gearbox, in which are incorporated two quickreverse friction clutches, three speeds in each direction being available. There is also a new method of irreversible steering, either power or hand-operated. A feature of the B-type roller which should not be missed. is the new method of cambering the rolls, the cambering device being located in the wheel and
the axle remaining tgid. The roller exhibited weighs 4 Items and has a rolling width of 4 ft. 6 ins. The engine is a four-cylindered petrol unit develop. ing 141 b.h.p. at normal speed.
The, third new model shown, a onetonner, is of an experimental type, and a production model similar in most respects will shortly be available. The tandem quick-reverse Q6-type roller (with a 28 b.h.p. four-cylindered petrol engine) primarily designed for use on asphalt, etc., and• weighing 6 tons without ballast, is another interesting exhibit, whilst the A-type 21-tonner, suitable for footpath and similar work, is also available.
CHASESIDE ENGINEERING CO. Enfield; London, N. Stand 115 (Gilbey Hall).
THE familiar Hi-lift and Lo-lift loading shovels areeach to be seen in improved form, the new K-type embodying many improvements over that shown at the 1927 exhibition.
The manufacturer, claims that the Chaseside is a one-man shovel with an output of eight men and that it will load a 5-ton lorry in 12 minates at a cost of 8d., including maintenance charges. The loading speed varies between 20 and 40 tons per hour, according to the material handled. The basis of the machine is the Fordson 25 h.p. tractor. It will pull 10-ton road wagons.
EAGLE ENGINEERING CO., LTD. Warwick Stand 8 (entrance Hall). Ave
THE name of this concern is well known to all of our readers, the company's trailers for road and industrial service being thoroUghly up-tot date and reliable.
The Eagle rotary dustless refuse collector, which has been on the British market for about a year now, constitutes the heavier of the two appliances shown, and it is seen mounted upon a two-wheeled trailer chassis for haulage by a tractor. The body is circular in section, being made of steel plates and having a capacity for about 8 cubic yards. On the front end is located a spindle and at the rear a large door, whilst on the near side are four patent loading doors to suit the special Ess-Em bins. Compensating rollers permit the house-refuse trailer, the capacity being between 6 and 7 cubic yards, or, say, 2h-3 tons. This is a new machine, the principal feature being the foot-operated canvas covers. It does not call for the employment of a particular type of bin and, whilst not expensive, fulfils in many important respects present-day
requirements. It has a low loading height and the foot-actuated covers certainly go far toward preventing the
escape of dust. .
ELECTRICARS, LTD. Lawley Street, Birmingham. Stand 17 (Main Hall).
MWO Electricar low-loading refuseccillection vehicles are available for inspection. The smaller one is a two. tonner fitted with patent covers to
prevent the escape of dust. It is specially designed for short hauls in competition with the horse-drawn vehicle.
The three-tonner is intended for longer journeys, and, whilst the particular example shown is equipped with the company's standard canvas covers, any type of cover desired can be fitted.
The overall length of the smaller model is 14 ft, and of the larger model 18 ft, 6 ins. The drive from the motor, in each case, is by propeller shaft and semi-floating worm-driven axle.
