Leeds.
Stand 41 (Main Hall).
MHE Fowler patent steam gully1 emptier, a three-wheeled Dieselengined, 10-ton road roller and a complete road-making plant are the items of particular interest on this stand.
The gully-emptieris a modern type of apparatus, consisting of a separate vacuum tank, a sludge tank, water tank and waste-water tank, the tquipment being mounted upon a standard steamwagon chassis.

three-wheeled roller operates on the atomization principle the fuel being injected straight into the cylinder in the ordinary manner. The injection nozzles are of the simplest type and are quickly accessible, and it is claimed that the machine is even cheaper in operation than a steam roller of similar size. A quick-acting reverse gear is provided and is operated by two simple toggle clutches carried outside the frame. The machine is equipped with power steerage.
The road-making plant has as its basis a steam road roller, and it is arranged for spraying surfacing mixtures at high pressure and for sprinkling grit or chippings by means of a patent machine which it hauls.
KERR, STUART AND CO., LTD. Stoke-on-Trent. Stand 83a (Main Hall).
THE new 7-ton Diesel-engined chassis of British construction, which was described in our issue for October 22nd, is seen for the first time at this exhibition. The Kerr Stuart K84 model is 21 ft. 6 ins, in overall length and 7 ft. 6 ins, in width; the wheelbase and track are respectively 13 ft. 6 ins. and 6 ft. 2 ins.
The engine is of the airless-injection n22 type developing over 60 b.h.p. at 800 r.p.m., at which maximum speed it is governed. There are four cylinders, the bore and stroke of which are 135 mm. and 200 mm,, and the overhead valves are actuated by totally enclosed rocker arms and push rods. Power is transmitted through a reverse-cone clutch, Ferodo-lined, to a for-speed gearbox, in which is housed a worm-type reduction gear and differential, the final drive being by roller chains to a dead rear axle.
The steel-disc wheels with tapered roller bearings have 36-in. by 8-in, pneumatic tyres, and twin tyres are carried on the rear wheels. As regards braking, the pedal actuates brakes on all four wheels, the hand brake operating only on the rear wheels. The front wheels have semi-elliptic springing and Marks steering. The springing of the rear axle is particularly interesting. There are two transverse springs placed side by side and, as, under compression, the spring ends move through different arcs, periodic rebound is prevented. There are, of course, strong girder-type radius rods, these incorporating ingenious chain adjusters.
The McLaren engine used in this lorry created an impression upon visitors to the recent Commercial Motor Show at Olympia, and it has several important advantages, the principal of these being, of course, that it is extraordinarily cheap in operation. Haulage contractors and others to whom cost per ton-mile is such a vital factor should not fail to examine carefully the merits of this machine.
R. A. LISTER AND CO., LTD. Dursley,
Stand 1 (Entrance Hall).
SEVERAL new models of the now famous Lister Auto-trucks are available for inspection upon this stand. Perhaps the most important is the truck with a swivelling tipping body, a recent improvement being the lower loading height.
There is a trtick equipped as a sweeper and sprinkler, and a narrow elevating truck, specially designed for factories, etc., where gangways are narrow ; also a long-wheelbase road type.
An attractive feature of the Lister Auto-trucks is the moderate price, and the running costs are relatively low. As evidence of their versatile utility it is interesting to note that there are in use in England to-day 46 models.
MARSHALL SONS AND CO., LTD. Gainsborough. Stand 70 (Main Hall).
SEVERAL of the Marshall road rollers, both steam and oil-driven, are staged here. An interesting model is the 8-ton, oil-driven, three-wheeled roller, which has a semi-Diesel, horizontal, heavy-oil engine.
Two steam rollers are also present, the 10-tonner being a three-wheeled, single-cylinder type with piston-valve engine. The Marshall patent firebox is used and the boiler is suitable for working at a pressure of 150 lb. per sq. in.
Then there is the Marshall Universal, a double-cylindered, high-pressure, quick-reverse engine intended for ordinary consolidation and for laying asphalt and similar surf icing. The engine works at a pressur of 180 lb. per sq. in.
A much smaller and tot Ily different roller is the Marshall M numit, the example shown weighing 1 cwt. This has a two-stroke petrol engine swung from the main axle, insid4 the roller, and transmission is through a flexible coupling and worm-type re uction gear, no chains being emplo d. It is steered by a man walking 'nd it.
