Albion Motor Car Co., Ltd.
The exhibit of the Albion Motor. Car Co., Ltd., on Stand No. 7, Row C, -will comprise a useful hydraulic tipping wagon which has been specially designed for the use of local authorities.
The tipping body is, mounted on a standard. 32 h.p. Albion chassis, which has a carrying capacity of 3i tons. It is built of strong and well-braced steel plates.
Most of our readers will know that in the Albion hydraulic ge.ar a light machinery oil is forced by a pump beneath the driver's seat to the tipping cylinder, which is carried on trunnion brackets secured to cross members. This pump is of the Hele-Shaw type, and is driven from the propeller shaft of the chassis by a substantial roller chain. The pump is 'brought into operation by the movement of a lever. conveniently placed to the driver's-left hand. Once the limit of the body's travel has been reached, a spring-loaded safety valve comes into action and the body remains in its tipping' position until the control lever is pulled in the reverse direction. It is claimed that the load can be tipped in one--aiul-a-quarter minutes and the body returned to its norma4horizonta1 position in about -45 seconds. The oil itsecl as a hydraulic medium is returned to
B32 the tank beneath the pump after one tipping operation, in readiness for the next. So far as the chassis is concerned, the four-cylindered engine develops 32.4 b.h.p. at 1,050 r.p.m. The bore and stroke of the cylinders are 114 rem. and 127 mm. respectively. The gearbox provides for three speeds forward and a reverse speed.
Associated Equipment Co., Ltd.
A four-ton mechanically-operated tipping wagon will be shown by the Associated Equipment. Co.' Ltd., on Stand No. 3, Row C. The body is constructed of metal, and the tipping gear is of the Bromilow Edwards hydraulic type. The construction of this chassis very closely resembles that of the . London omnibus. , The engine is a 45 h.p. four-cylindered one, with the cylinders cast in pairs. The frame is of the wood and flitch plate construction. The drive is taken through a four-speed and reverse gearbox to a worm-driven back axle provided with a cast-steel central casing with cast steel extension pieces and spring brackets. The lid of the easing forms a housing for the worm, and the differential is slcuig from it, thus facilitating the removal of the worm and differential without disturbing the rest of the axle.
Anglo-American Oil Co., Ltd:
On Stand No. 1, Row A, various grades of the asphalt products of the Anglo-American Oil Co., Ltd., will be shown. These products, it, is stated, cover the full range of requirements for asphalt work of all kinds. Further information and leaflets may be obtained at the stand.

Buford and Perkins, Ltd.
The old-established concern of Barford and Perkins, Ltd., of Peterborough, will, as might be expected, be showing on Stand No. 9, Row D, two of their heavy-type road rollers. The lighter machine weighs seven tons empty and nine tons full, and is well adapted for the needs of municipal engineers. It is driven by a 20 h.p. two-cylindered Dorman engine of -neavy construction, which is governed at 950 r.p.m. It. is fitted with a Bradburn-Cox vaporizer, which will enable the engine to use paraffin as a fuel. The gearbox provides for two steeds in either direction, and it is claimed that the machine will easily tackle a gradient of one in six.
The heavier of the two exhibits weighs 10 tons empty and 12 tons fell. This roller has a 40 h.p. four-cylindered Dorman engine, and, as in the case of the lighter model, a BradburreCox vaporizer is fitted for the u,se of paraffin. In point of construction, this machine is almost identical to the lighter model.
British Four-wheeled Drive Tractor Lorry CO.
The only four-wheel-drive lorry to be seen at the exhibition will be shown on Stand No. 10, Row B, by the British Four-Wheel-Drive Tractor Larry Co. We described this vehicle at some length
in our issue for August 5th last. It may be remembered that the power unit is of Dorman manufacture, and it develops 44 b.h.p. at 1,100 r.p.m., corresponding to a speed on top gear of 14 m.p.h. The power is transmitted through a substantially-built five-plate clutch, consisting of two fixed steel plates and three Ferodolined floating plates. Flexibility is obtained by a spherical coupling on the gearbox shaft. The gearbox provides for three forward and a reverse speed. The drive from this box is taken through a silent Renold chain to a central differential, and from this differential cardau shafts convey the power to bevel gearing on the front and rear axles. Each of these axles is also provided with a differential, making a total of three for the vehicle.
Both axles are of the full-floating type, the entire weight of the vehicle being taken on the axle casings front and back.
The body is of slightly over three-ton capacity, and is designed for the express parpoee of transporting loose coal. It is divided into three sections.
British Reinforced Concrete Engineering Co., Ltd.
The use of reinforced concrete for road construction is comparatively new, but there is little doubt that for some classes of road and for ustawhen the foundations are unstable it will replace other methods of construction. The exhibit of the British Reinforced Concrete Engineering Co., Ltd., on Stand No. 7, 'Row F, will therefore compel attention. It will consist of a sample Of reinforced concrete stab such as is used in the construction of reinforced roads, and a separate sample roil No 9 B.R.C. fabric which is the size of reinforcement almost univer sally used in these roads.
H. G. Burford and Co., Ltd.

Caledon Motors, Ltd.
Caledon Motors, Ltd., will show on Stand No. 9, Row C, a four-ton tipping lorry fitted with a. steel tipping body. The gear used is the Edward hydraulic hoist fitted with a doable ram, and operated from the engine.
This vehicle is fitted with a new type of 40 h.p. engine of particularly interesting design. The four cylinders are cast in pairs, the exhaust ports being situated on the near-side, and the inlet ports on the off-side. The valves are of the single sleeve type, constructed under the Bart-McCollum patents, previously known as the Argyll single-sleeve valve.
In the Oaledon engine a greatly simplified method of operating the sleeves is introduced, a simple crank and short connecting rod giving the elliptical motion to each sleeve.
The cylinder heads are detachable, and large covers arc also provided on each cylinder so that the water jackets can be cleaned when necessary. The bore and stroke of this engine are 110 mm. by 140 mm. respectively. The h.p. is 44 at an engine speed of 1,300 r.p.m. The final drive is by chains, and stout radius rods are provided. The wheels are all of the east-steel tubular type. Caledon lorries in municipal service have given every satisfaction to their users
• Clayton and Co., Ltd.
One of the most interesting exhibits which is bound to rouse considerable attention is the patent sprinkler, „road sweeper and refuse collector which is being exhibited by Clayton and Co., Huddersfield, Ltd., on Stand No. 12. Row B.
The Clayton street sweeper first sprinkles the road with just sufficient water to slack the dust, when it is brushed into the collector which conveys it into this hopper in a dustless form. At the front of the machine, irinnediately behind the sprinklers, are placed two brushes which operate, tangentially. These brushes sweep at the extreme width of the machine, throwing the refuse into the centre, from which the rear brush collects it and throws it into the pan and conveyor. By this means the total Width of 7 ft. 6 ins, can be sprinkled and swept in one operation. The brushoperating mechanism is quite antornatic, and only .,COPIes into operation when
lowered for sweeping purposes. Elevating the brush throws the operating mechanism out of gear and enables the machine to be used as an ordinary motor vehicle, for the purpose of carrying the collected refuse to a discharge dump, The road brushes are mechanically hung and balanced so that they float over the road surface and, no matter what, the condition of the road, the work can be carried out efficiently.
