The Derby Electric Wagon.
STAND No. 54.
rHE Newton chassis is of unusual de
sign, embodying two motors, one e each rear wheel, which it drives .hrough the medium of pinion and inernal rack. The motor in each case is ,uspended at. the end of a short radius • oel, which at its front end takes a bear. rig on the dead axle of the vehicle. ['he driving torque and thrust are transnitted by is semi-elliptical rear spring. iThe arrangement of the driver's cab on his machine is also unusual ; the floor ioards are sunk well below the level of be chassis frame, which is about the arne height as the driver's seat. This ,rrangement not only makes the cab conrenient of access, but affords the driver tri unusually clear and uninterrupted rimy of the road.
The principal exhibit on this stand is a tipping wagon. The motive power for this is derived from a special motor, which drives a longitudinal screw through the medium of chain gear The preliminary motion of the body is to the rear. After a time, pulleys on the under side come in contact with an inclined ramp, which lifts the body just when it is about to lose ita equilibrium and tip automatically: It is prevented from being pushed back too far by a pair of hooks which come in contact with pulleys on the chassis, while a ,similar arrangement of hooks and pulleys locates it in the forward position. The batteries are located in a transverse tray beneath the Chassis, and are accessible by withdrawal from either side.
One of the most interesting points about the Newton is the springing arrangement for each of the driving motors. This prevents • damage to the motors by vibration; as all shocks are passed through tveo series of springs.
