I, JOHN CARRINGTON SELLARS, of 68 Bridge Street, Birkenhead, in the County of
Chester, Manufacturing Chemist, do hereby declare the nature of my said invention to
he as follows :-
My Invention has chiefly for its object to give a high speed to shafts and rotary
machines.
According to my Invention I combine a wheel, or pinion, a motor for rotating such
wheel, or pinion, a flexible shaft" and a shaft or machine driven by the said
"flexible shaft," in such a manner that the wheel or pinion and "flexible shaft" moves
or is free to move about the axis of its motor.
be a
The motor for driving the wheel or pinion may sun and planet motion" or
differential toothed wheel, or friction gear, or other like, or equivalent gear run at
equal, or differential speeds.

page_text: Figure 1 is a perspective view, showing an example of an apparatus according to
my Invention for transmitting rotary motion to shafts or machines; in this case an
internal toothed wheel and a toothed pinion are used.
Figure 2 is a side elevation of an apparatus according to my Invention, in which a
rope is used to transmit motion.
Figure 3 is a side elevation of an apparatus according to my Invention, in which a
chain band is used to transmit motion.
On reference to Figure 1 of the Drawings, a is a motor wheel, having internal
teeth a' this wheel a is fixed on a hollow shaft b, and supported in any suitable
bearings, and caused to rotate in the direction of the arrows 61 by any suitable motor.
e is a flexible shaft fixed to a solid shaft c', which is supported and runs in bearings c²
on an arm d, which is fixed and carried on a shaft e which passes through the hollow
shaft b, and is caused to rotate in the direction of the arrows e' by any suitable motor
(the motor for the shafts and e may be a toothed wheel gear h, such as shown at
Figures 2 and 3). On the shaft e¹ there is provided a toothed pinion & which gears
into the teeth of the wheel a. The flexible shaft c is supported by and runs in a
bearing, carried on the shaft e, and the end of the shaft is provided with a
coupling g, by which it is connected to the shaft or machine to be driven.
In operation, through the shafts b and e being caused to rotate in the opposite
directions, the pinion & moves round the axis of its motor wheel a, and at the same

page_text: time is caused to rotate on its own axis, by the movement of the wheel a thus a
great increase of speed is given to the pinion k and flexible shaft c, over the speed of
the motor wheel a and its shaft b.
In the example of an apparatus according to my Invention shown at Figure 2, a
rope a and a pulley are employed instead of the teeth a', and pinion k, shown in
Figure 1, the pulley k being driven by an endless rope a' from the drum a.
In the example of an apparatus according to my Invention shown at Figure 3, a
chain wheel a and pinion wheel are employed instead of the wheel a and pinion k,
shown in Figure 1, the wheel being driven by a chain a¹ from the wheel a.
In all the examples shown, the pinion, pulley or wheel is free to move or to be
moved about the axis of its motor a., and is thereby given a very high speed over that
of its motor. I would have it understood that the speed of the shafts 6 and e may be
the same, as provided for the gear h; or the speed of the shafts bande may be of
any differential speed as desired. I would also have it understood that the motor a
and device k may be connected by tooth gear, a rope or band, a chain or frictional
contact or their equivalent.
It will be obvious that instead of the apparatus being used to impart a high speed
to a shaft or machine, it may be used to impart a slow or reduced speed to the wheel a
from a high speed shaft.
Having now particularly described and ascertained the nature of my said Inven-
tion, and it what manner the same is to be performed, I declare that what I
claim is :-
1. In apparatus for transmitting rotary motion to shafts or machines, the com-
bination of a wheel or pinion, and a flexible shaft, said flexible shaft being connected
to the pinion and to the machine to be driven, and the said pinion and flexible shaft
being free to move about the axis of its motor; substantially as set forth.
2. The combination of parts claimed in claim 1, wherein motion transmitted through
the flexible shaft to the pinion.
3. The combination of the wheel or pinion k, motora and flexible shaft c,
carrying arm and shaft e, as set forth with reference to Figure 1 of the
Drawings.
4. The combination of the pulley k, motor a, and flexible shaft c, carrying arm l
and shaft e, as set forth with reference to Figure 2 of the Drawings.
5. The combination of the wheel k, motor a, and flexible shaft c, carrying arm
and shaft e, as set forth with reference to Figure 3 of the Drawings.
Dated this 20th day of September 1888.
