LIVERY exhibit on the Sunbeam .La stand is electric. By reason of their recent introduction, the battery electric goods vehicles should, perhaps, have prior notice. Two machines of this type are on view, both making their first public appearance. One is seen in chassis form.
Electrical equipment has been specially designed by the B.T.H. Co., and includes a ventilated motor con. trolled by magnetic contactors of a design similar to those used on Sunheam-B.T.H. trolleybuses. The contactors are operated by a pedal which , actuates the master controller. The system of control enables speed to be regulated as in an internal-combustionenginecl vehicle and leaves both hands free for steering, etc.
With a wheelbase of 6 ft. and an overall chassis length of 11 ft. 9 ins., a platform space of 7.ft. hf ins. is provided behind the cab. The chassis exhibited has D.P. batteries, but other makes can he supplied.
The other 12-15-cwt. model has a special vat body by Glover, Webb and Liversidge, Ltd., and is one of a 'number of similar vehicles supplied to Selfridge and Co., Ltd. In this case, the chassis has a wheelbase of 12 ft. 8i ins., affording a platform length of 9 ft.
For trolleybus operators there are,
four exhibits of interest. One is an M.S.2 long-wheelbase six-wheeled chassis, built to the requirements of Belfast Corporation, whilst another M.S.2 carries a 60-seater body, to the order of Walsall Corporation.
Two M.F.2 four-wheelers appear, one having a Park Royal 54-seater body for Wolverhampton Corporation and the other an M.C.W. 60-seater body for the City of Johannesburg. B.T.H. electrical equipment is incorporated in all models.
In the M.S.2 long-wheelbase chassis,
which issuitable for bodies seating up to 70 passengers, a 95 b.h.p. compoundwound, field-type motor, arranged for regenerative and rheostatic braking, is provided. It is carried on a subfra.me flexibly mounted at four points, the complete assembly being easily removable.
The master controller is combined with a reverser. Both the main and shunt-field resistances are carried by the chassis side members, where they are readily accessible. Sunbeam-Lockheed hydraulic braking takes effect on all six wheels, a feature being a patented compensating and sealing device. The rear bogie embodies twin-spring suspension.
In the M.F.2 four-wheeler an 80 b.h.p. motor is incorporated. The vehicle for Johannesburg is particularly worthy of inspection.—Sunbeam Commercial Vehicles, Ltd., Mciorfield Works, Wolverhampton.
