Details of a Useful Type of Berliet for Road Construction and Other Work of this Nature or Refuse Collection.

TIIE commercial motor vehicle, as we showed in our last issue, continues to meet with considerable success in all branches of municipal work, particularly for refuse collecting and also on road construction. Both these spheres of activity call for a body from which the load can be discharged quickly and with a minimum of labour. The solution of these two desiderata is the tipping wagon, and Automobiles M. Berliet, of 40, Sackville Street, London, W.1, have for many years •specialized in the construction of these vehicles, several of which have been supplied to customers in the north of England.

The chassis on which these bodies are mounted is their well-known 5-ton heavy duty model, recently described in The Comaturcial Motor. This chassis is equipped with a four-cylinder engine, having a bore of 110 mm. and a stroke of 140 mm. and developing 38 lip, at 1,250 r.p.m. The engine is fitted with centrifugal governor, and a multi-plate clutch running in oil conveys the drive to a four-speed and reverse gearbox in which is embodied the differential gear and the jack-shafts for the small chain sprockets, the final drive being by side roller chains.

Mounted on the propeller shaft, between the clutch and the gearbox, is a subsidiary gearbox housing the mechanical tipping gear. The construction of this gear can be seen in one of the illustrations. Mounted on a splined section of the propeller shaft is a gear wheel, which meshes with another gear wheel, bolted and keyed to a worm shaft lying parallel with the propeller shoft. This worm shaft drives, by means of a worm, a transverse shaft, on the outer extremities of which are mounted two drums.

To these drums are attached wire cables, which pass over pulleys mounted on jibs at the rear of the driver's cab and down to the front end of the body. When it is desired to operate the tipping gear, the clutch is disengaged, the sliding gear wheel meshed with the gear wheels on the worm shaft by means of a hand lever mounted at the driver's right, outside the cab, and the clutch then let in. This causes the drum on the transverse shaft to revolve, winding up the rope and lifting the body automatically. A disengaging clutch is fitted which prevents the body tipping beyond a certain height.

To lower the body, the sliding wheel is meshed with an intermediate wheel between it and the worm shaft, thus reversing the motion of the latter. The automatic cut-out functions when the body is lowered, throwing the mechanism out of operation as ttie body comes to rest on the chassis.

The vehicle is supplied either with a steel open body for road construction and similar work, this being the standard model, or with a special body fitted with hinged covers for refuse collection.

The 5-ton tipping chassis has the same wheelbase as the standard lorry, viz., 15 ft. 9 ins. The Price is £720.
