a ‘../combination of forces between two important concerns. The Sewer Company, with its works at Arbon in Switzerland, has a fine nanie'for the quality and sturdiness of its vehicles.
The company has now madm an arrangement with the well-known Armstrong concern by which the Armstrong-Saurer vehicle embodying Sewer principles and patents will be built in this country.
At present the newly formed Armstrong-Saurer concern is concentrating on a few heavy chassis available with either oil or petrol engines. The former bear names 4beginning with D, and the latter names beginning with P.
In each class there are four-cylinder and six-cylinder chassis suitable for loads of 6 tons, these being fourwheelers, and there is a six-wheeler having a six-cylindered engine and being suitable for loads of from 11 tons to 12 tons. Only oil-engined models are being exhibited at Olympia—a rather significant fact.
The first exhibit is the Defiant fourcylinder six-tonner, having an oil engine of 110 mm. bore and 180 mm. stroke developing 52 b.h.p. The chassis weigh; about 3 tons 12 cwt. and the wheelbase is 14 ft. 9 ins. Single-reduc tion bevel drive with totally enclosed universal joints provides the final stage of the transmission. The machine has Armstrong-Saurer Simplex steel wheels carrying 40-in. by 8-in, pneumatic tyres, with twin tyres at the rear.
Secondly, there is the Dauntless, which, it may be mentioned for the benefit of old Saurer users, corresponds approximately to the 6BLD type. Two examples of this chassis are shown, both having six-cylinde red 90 b.h.p. engines of 110 ram. bore and 150 mm. stroke, four-speed gearboxes and, of course, fully floating back axles. One has a wheelbase of 16 ft., whilst the other, which is polished for exhibition purposes, has a wheelbase of 16 ft. 4 ins. The unpolished chassis is the first all-British Armstrong-Saurer to be exhibited.
The fourth exhibit is the Dominant rigid six-wheeler having the 90 b.h.p.
Loads
engine and being suitable for loads of 12 tons. Details of the power unit in this powerful vehicle are worthy of consideration. The mounting of the cleanlooking oil engine, for example, is at three points, a rubber sleeve being employed at each. It is noticed that the cylinders of this engine are cast monobloc fashion integrally with the crankcase, so that excellent rigidity is obtained. The cylinder head, incorporating the totally enclosed -overhead valves, is, of course, detachable.
The rear bogie is one of the most
striking features of the Show. The drive is taken to a central axle which extends almost to the full width of the vehicle in a casing fixed to the centres of two 9-ft. 6-in, laminated springs, each comprising five leaves 41 ins, wide and 1-pg in. thick. This axle carries two rocking-beam housings on which are mounted the four road wheels, the power being transmitted to each wheel through a' shaft having right-angle gearing at its ends.
Two examples of the six-cylindered engine are shown, one complete with gearbox and the other a seetionized model showing the principal working parts.—Armstrong-Saurer Commercial Vehicles, iitd., Scotswood. Newcastleupon-Tyne.
