PROVISIONAL SPECIFICATION.
Improvements in or relating to Transmission Gear for Self-
propelled Vehicles.
I, WILLIAM BAINES, of 5 and 6, Great Winchester street, in the City of London,
Financial Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to the transmission of the power in self-propelled
vehicles. This is easily effected by belts or toothed gearing but in carrying out
my invention I employ a rope or cable running in or upon suitable pulleys or
drums preferably grooved for the purpose. This is particularly useful where I
have the fly wheel rotating in a horizontal plane as the rope accommodates
itself readily to the change of direction of motion from the fly wheel or engine
shaft to that of the road wheels of the vehicle, the pulleys employed for effecting
this change of motion being applicable also as jockey pulleys to secure or prevent
the necessary tightness of the rope according as it is desired to drive or to slip.
If the fly wheel be not placed upon the engine shaft but merely connected there-
with the rope may be used as the means of transmission of power from the engine
shaft to the fly wheel or to its shaft or boss and either directly or indirectly from
there to the counter shaft or road wheels.
The ropes may be boxed in if desired, but as they are not so easily effected by
exposure to the weather or dirt this is not of such importance as in the case
of belts or toothed gears.

Improvements in or relating to Transmission Gear for Self-
propelled Vehicles.
I, WILLIAM BAINES, of 5 and 6, Great Winchester street, in the City of London,
Financial Agent, 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 :-

This invention relates to the transmission of the power of self-propelled
vehicles. This is easily effected by belts or toothed gearing but in carrying out
my invention I employ a rope or cable running in or upon suitable pulleys or

this change of motion being applicable also as jockey pulleys to secure the neces-
sary tightness or slackness of the rope according as it is desired to drive or to slip.
If the fly wheel be not placed upon the engine shaft but merely connected there-
with the rope may be used as the means of transmission of power from the engine
shaft to the fly wheel or to its shaft or boss and either directly or indirectly from
there to the counter shaft or road wheels.
The ropes may be boxed in if desired, but as they are not so easily effected by
exposure to the weather or dirt this is not of such importance as in the case
of belts or toothed gears.
In the accompanying drawings
Figure 1 is a plan,
Figure 2 a side view and
Figure 3 an end view showing a convenient method of applying this invention
to a four wheeled auto-car.
Like letters indicate like parts throughout the drawings.
The main frame of the car comprises side pieces A A¹ and cross bars A2 A3 A4
The engine B has a, in this case, vertical main shaft B₁ supported on the cross
bar A of the frame and carrying the driving pulley B2 on its lower end. The
driven pulleys CC, for fast and slow speeds respectively, are placed on the axle D
of the road driving wheels. On the rear cross bar A' of the frame is a horizontal
arm E, one end of which is pivotted on the cross bar by a pin E¹ whilst its free
end is furnished with a vertical pin E2 on which are carried two pulleys E3 E
free to rotate on said pin. The free end of the arm is also provided with a lug E
to which is pivotally attached one end of a connecting rod F.
The other end of the rod F is connected to one arm of a bell crank lever G
pivotted on to the side frame A¹, the other arm of which is pivotted to a toothed
bar H. This toothed bar H is placed below and in front of the vehicle seat (as
shown in Figure 2) so as to be conveniently manipulated by the occupant of the
car, and is carried in a slotted lug or projection J, provided with teeth to engage
the teeth of the bar.
As shown in the figure the bar H is adapted to be worked by the foot, it is
evident it may be arranged for operation by the hand, and may be given a screw
action instead of ratchet teeth as shown.
The driving rope or power transmitter K passes from the driving pulley B² back
to the idler pulley 13 and in the arrangement shown in the drawings it is then
carried forward beneath a stationary idler L over the driven pulley Cor C¹, from
below which it passes back to the idler pulley E and thence back to the driving
pulley B². By this arrangement a very long rope or equivalent is obtained.
By operating the bar H the power transmitter can be tightened or slackened as
desired. By pressing down the lever the arm E by the action of the bell crank
lever G and connecting rod E, is swung back carrying with it the idlers E3 E4
and tightening the transmitter and since four runs of the rope are effected, the
amount of slack taken up will be four times the length through which the arm
has been swung. By engaging the teeth on the bar with the corresponding teeth
in the slot the arm and its pulleys are held in the desired position, whilst by
releasing the bar H the transmitter is at once slackened.
Although I prefer to use a rope or cable of circular cross section I do not bind
myself to any special section, and it is evident that flat ropes or belts could be
used with this method of driving.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:―
1. In transmission gear for self-propelled vehicles the combination with an
engine placed approximately in the longitudinal centre of the vehicle a driven

page_text: shaft or part at one end of the vehicle and two idler pulleys at the other end of the
vehicle of a rope or equivalent power-transmitter connecting these parts sub-
stantially as and for the purpose described.
2. In transmission gear for self-propelled vehicles the combination with an
engine placed approximately in the longitudinal centre of the vehicle a driven
shaft or part at one end of the vehicle and two idler pulleys running in opposite
directions and one or both of them adjustable at the other end of the vehicle of a
rope or equivalent power-transmitter connecting these parts and having its
separate runs passing round the respective idler pulleys substantially as and
for the purpose described.

3. In transmission gear for self propelled vehicles the combination with an
idler pulley for belt-tightening purposes of a lever or other device operated from
the driver's seat whereby the power transmitter can be tightened or slackened
while the vehicle is running and the rate of travel varied thereby substantially
as described.
4. In transmission gear for a self-propelled vehicle the combination with a
driving pulley and a driven pulley of one or more wheels such as E3 E carried on
a swinging arm such as E and a device under the control of the vehicle operator
for varying the position of said arm substantially as described.
5. The transmission gear for a self-propelled vehicle substantially as described
or as illustrated in the accompanying drawings.
