Improvements in Motor Carriages.
We, THE HONOURABLE REGINALD THOMAS DUDLEY BROUGHAM, Gentleman, of
22a, Dorset Street, Portman Square, and WALTER CHARLES BERSEY, Electrical
Engineer, of 28, Victoria Street, Westminster, both in the County of Middlesex,
do hereby declare the nature of this invention to be as follows:-
In motor carriages it is usual to carry the electric or other motor on a frame
fixed to the body of the carriage and to drive by a chain passing over chain
wheels on the motor and carrying wheels respectively. Since springs are inter-
posed between the body and carrying wheels it is necessary in such cases to provide
means for keeping the chain tight and this is usually done by means of radius
rods connecting the axles of the chain wheels. This arrangement however has
inconveniences.
According to this invention we mount the motor in guides on the frame and
provide a spring or springs tending to draw the motor along the guides away
from the axle of the road wheels so keeping the chain tight.
Dated this 18th day of May 1898.
