Exhibit —A Three-ton, Open Lorry ; a Convertible Military Wagon; an Omnibus Chassis ; and One 28-52h.p. Engine.
Sir \V. G. Armstrong, Whitworth, and Co., Ltd., of Newcastle-on-Tyne, is exhibiting one type of chassis only-the three-ton, or omnibus, type. It has not been found necessary to alter any important details, since a similar machine ran so satisfactorily through the recent R.A.C. Trials.
We noticed the carefully-thought-out arrangement of clutch-operating gear, and spring-mounted clutch stops. In this arrangement, a small leatherfaced pad, mounted on twin swing arms, to obtain parallel motion normal to the clutch plane, is carried on the inner frame on each side of the clutch. The clutch adjustment rod and spring are properly accessible, and situated immediately under the floor'boards.
The 28-32h.p. engine has a bore of 4 5-16 inches, and a piston stroke of 5.1 inches ; it is rated at 32h.p., when running at 000 revolutions per minute. As might be expected On a machine bearing the name of one of our greatest engineering works, all the material .employed is of unexceptionable quality ;
the crankshaft, in particular, is an excellent piece of construction and is machined from a solid, nickel-chrome, steel forging. A fully-illustrated description of the complete vehicle, with some views of the works where it is constructed, appeared in " THE COMMF.RCIAL MOTOR " dated the 21st February, 1907.
The 28-3211.p. Arrnstrong-Whitworth convertible military wagon, for the transport of troops and baggage, either separately or together, is an interesting example of a standard machine adapted to specialised work. Broadly speaking, the body, which is, of course, the distinctive part of the machine, consists of a large area platform lorry, with special removeable sides. These sides, when the wagon is used for the conveyance of baggage only, are supported by iron brackets, five in number, on each side, which subsequently serve the purpose of supports for the seats. When it is desired to convey troops, the sides are taken down, and 'fitted across to the iron uprights, rapidly converting the machine from a baggage-carrying lorry into a more or less comfortable char-it-bancs. Other special features consist of : a folding shelf, attached to the dashboard, presumably for an officer to consult maps or other documents on ; very ample lockers at every available corner of the underfrarne; extra-size mudguards; and various brackets, etc., for attaching implements.
