Improvements in Road Vehicles Driven by Motors, particularly
Oil Motors.
JOHN HENRY KNIGHT Barfield, Farnham, County of Surrey Engineer and
Landowner do hereby declare the nature of this invention to be as follows:-
My invention consists in the method of driving the road wheels of a petroleum
carriage I fit on the crank or driving shaft of the engine two or more pulleys,
driving by means of two or more flat belts different speed pulleys on the inter-
mediate, or even on the road axle, these give the variation in speed such as 3, 6,
or 10 miles per hour, all the belts are loose and each one can be tightened as
desired at the will of the driver by jockey pulleys.
A crossed belt is also used for running backwards.
Fourthly I connect the jockey pulleys with levers or handles in front of the
steersman's seat by rods cords or any mechanical equivalent.
This arrangement is applicable to carriages propelled by other motors than gas.
or petroleum such as steam or electricity.

JOHN HENRY KNIGHT Barfield Farnham County of Surrey Engineer and
Landowner do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
To drive the road wheels of a gas or petroleum carriage, I fit on the crank
shaft of the engine two or more pulleys driving, by means of flat belts, different
speed pulleys on the intermediate shaft, or even on the road axle ; these give
variations of speed such as 3, 6, or 10 miles per hour, (the engine running at a
uniform speed). All the belts are slack or loose, and until tightened by the jockey
pulley opposite each belt & provided for that purpose, the engine simply runs light,
& does not move the vehicle. The handles for moving the jockey pulleys are
arranged that the steersman or driver has them in some convenient position, they
may be moved by cords rods or any mechanical equivalent.
I disclaim the use of round guts or cords running in V pulleys.
A crossed belt is used for moving the vehicle backwards.
This arrangement is applicable to carriages propelled by steam or electricity.
The drawings Figs. 1 & 2 represent a small motor carriage or motor cycle fitted
On the crank
with my arrangement A is the cylinder, B crank shaft of the motor.
shaft are two pulleys of different diameter C and D, the smaller one C is opposite
the larger pulley C C on the intermediate_shaft H, the large pulley D on the
crank shaft is opposite the smaller pulley D D on intermediate shaft. The belt.

page_text: connecting the pulleys is shewn in Fig. 1 (one belt only being shewn for sake of
distinctness).
This belt is tightened by the jockey pulley E; carried on the handle or
lever B F, a rack at G holds the lever in any desired position.
The intermediate shaft H drives by chain J the road wheels K. S steering
wheels.
A cross strap or belt may be fixed on crank shaft beyond fly wheel L for
running backwards.
CLAIM.
Driving the road wheels of a motor carriage by two or more flat belts, for
variation of speed, running on different sized speed pulleys, and throwing each
belt into action by means of tightening or jockey pulleys.
Dated this 26th day of August 1896.
