A Complete Report, Arranged in Alphabetical Order, of all Heavy Vehicles to be Seen
at Glasgow.
A.E.C.
Tw° vehicles comprise the exhibit of
the Associated Equipment Co., Ltd., and these are staged on Stand No. 35, which is occupied by the Peric Motor
Ltd., of Edinburgh. Co.,ne of the machines is a 30-seater charbehancs, whilst the other is the standard 45 h.p. chassis fitted with a steel tipping body. ,
It would be superfluous to enter into a description of the technical details of the A.E.C. chassis, BA these are particulaely well known to most of our readers.
The tipping gear on the 45 h.p. chassis is a Bromilow and Edwards hydraulic equipment. It is said to be capable of clearing a full load of four tons in 20 • seconds. The full angle of tip is 40 degrees, but if it shouid be desired to discharge a portion of the load only, the tipping handle can be regulated at will, the gear. being controlled either from the Bide of the chassis or from the driver's. seat. The vehicle shown lia.s a hydraulic gear, driven from the gearbox, but another system is available which embodies a friction drive off the engine flywheel. An interesting detail exhibit an this stand is a capstan intended far drawing on to the body, up a vamp, individual items of a load, and this is particularly applicable, for example, to brewers' lorries. The capstan will haul a one-ton load with ease on to the standard type lorry body.
Albion. •
ONE of the most comprehensive exhibits in the Show is that of the Albion Motor Car Co., Ltd., who have no fewer than four vehicles on view on Stand No. 5. These comprise a standard 32 h.p. four-ton chassis, fitted with a c34, platform body; a 32 h.p. char-h.-banes 'chassis, fitted with a 29-seater torpedo body; a 20 h.p. 30-cwt. chassis, fitted with a box-van body; and Is 32 h.p. hydraulic tipping wagon. It would be superfluous to refresh the minds of our readers with the constructional details of Albion vehicles, but we will take this opportunity of briefly describing the operation of the hydraulic tipping gear. In the Albion gear a light mineral oil is forced by a pinnei beneath the driver's seat to tile 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 sub stantial roller chain. The pump is brought into operation by the movetnent of a lever on the left-hand side of the driver. Once the limit of the body's travel has been reached, a spring-leaded safety valve comes into action and the body remains in the tipping position until the control lever is pulled in the reverse direction, when the oil is pumped back into the storage tank and the body returns to the horizontal position, It is said that the load can be tipped in about minute and the body returned to its normal position in 45 seconds The driver's cab on this vehicle is fitted with high-sided doors.
The vehicle is painted dark green, with black and red effects, and it has been purchased by the Highland Distilleries Co., Ltd., of Rothes. All the vehicles shown on the Albion Company's stand are ready to go direct into service. The Albion tip wager' has, as a type, received much favour, amongst British users, particularly amongst municipalities.
Alldays.
A TWO.TON 25-30 h.p. Alidays lorry is shown by Reen.leigh, Ltd., of Edinburgh on Stand No. 9. This vehicle has a four-eyliiidered governed, engine 100 ram. bore by 130 mm. stroke. The cylinders are cast in pairs and bolted on to an aluminium crankcase. Forced lubrication is provided to the crankshaft and connecting rod bearings. The cooling water circulation is thernmesyphonie. The radiator is a cast aluminium header and bottom tank type. • The cone type of dutch is lined with Ferocio, and has auxiliary springs under the-leather. The gearbox is a, one-piece tasting with large inspection cover, and provides three epeede forward and reverse. The transmission from gearbox to rear wheels is through a self-contained beveldriven countershaft, and thence by roller chains running in oil-retaining metal cases.
Austin.
THE Glasgow agents for the Austin chassis, David Carlow and San, Ltd., are showing one of this company's new 30-cwt. lorries on Stand No, 4. This in the first opportunity afforded the public to examine this ehassis, which is intended for speedy delivery work. The new vehicle has an engine of 22.4 h.p. R.A.C. rating. and is a monobloe casting of four cylinders, with a bore of 3,1 ins and a stroke of 5 ins. The valves are all on one side, and the inlet pipe is formed in conjunction with the exhairet manifold. Petrol is gravity-fed from a 15-gallon tank on the dashboard. Ignition is by high-tension magneto, and cooling is effect-d by a centrifugal pump and gilled tribe radiator. The engine has forced lubrication supplied to all bearings through channels in the crankshaft. A single plate clutch is incorporated and a gearbox giving four forward speed, the control lever being mounted centrally
on the top of the box.
Final drive is by overhead worm gear to a floating live axle, the road wheels being carried on stationary tubes.
The footbralie operates internal shoes of large diameter no the rear wheels. The wheels are detachable, and are fitted with cushion tyres as standard.
We hoped this week to have been able to have dealt separately with this new Austin production. but owing to pressure on our space we have been compelled to omit a more comnlete description. We shall, however, take an early opportunity of placing before our readers a well-illustrated description of this new li-ton model. Several components of the lorry are also on view, including pistons and connecting rods, five-journal crankshaft, a one-piece camshaft, and the robust worm gear made by David Brown and Sons.
Beardmore.
THE Beardmore taxicab chassis is being shown on the company's stand, No. 11. As there are several interesting points in the design of this chassis, we have thought it aelvisable to deal with it more fully, and we therefore refer our readers for a description' of it to pageS 584 and 585 in this issue.
Berliet,
AFOUR-TON specimen of this French-built vehicle is shown on Stand No. L3 by the Glasgow and Paris Motor Garage and Repairing Co., Ltd.
