PROVISIONAL SPECIFICATION.
Improvements in or Connected with Apparatus for Driving Carding
Engines and other Machinery.
I, WILLIAM HENRY RATCLIFFE, of the Riaboff Mill Company, Serpuchoff, in the
Empire of Russia, Mill Manager, do hereby declare the nature of this invention
to be as follows:-
This invention is designed to provide for the more economical driving of carding
engines and other machines as I find that I am enabled to drive by means of ropes
instead of belts on fast and loose pulleys as has hitherto been customary.
I construct a driving pulley with one or more grooves for carding engines prefer-
ably two one of greater diameter than the other. This grooved or rope pulley I
mount upon a conical or other friction bush upon which in certain positions it is
free to rotate. The friction bush or cone is keyed or otherwise attached to the shaft
to be driven and the pulley is capable of lateral movement to a limited extent.
The boss of the pulley is formed with a groove and a clip in the form of a fork or
band engages therewith to move the pulley to one side or the other. Very little
movement of the pulley is required to cause it to engage or disengage with the
friction bush. In an alternative arrangement the bush may be capable of being
moved along a feather or key fixed in the shaft.
The bush for a portion of its length is cylindrical and the boss of the pulley for
a certain distance corresponding thereto is cylindrical internally.
The lever for starting and stopping the machine can be placed in a more con-
venient position than heretofore and no handling of belts or straps is required. .

Improvements in or Connected with Apparatus for Driving Carding
Engines and other Machinery.
I, WILLIAM HENRY RATCLIFFE, of the Riaboff Mill Company, Serpuchoff, in the.
Empire of Russia, Mill Manager, 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 is designed for the more economical driving of carding engines
and other machines.

the machine may be set in motion or caused to stop.
My present object is to provide mechanism whereby I am enabled to drive by
means of ropes and the fast and loose pulley arrangement with movable strap may
be done away with.
The invention will be fully described with reference to the accompanying draw-
ings in which as an example it is shown applied to a carding engine in which
sufficient of the machine is shown to illustrate the application thereto of the
invention.

Fig. 2. Plan.
Fig. 3. Side elevation of a modified arrangement.
Fig. 4. Plan of same.
Figs. 5, 6, 7 and 8. Details showing different constructions of the pulleys.
The driving pulley A is constructed with one, two or more grooves a in its
periphery to receive ropes according to the power required to drive the machine
or the secondary driving to be carried from the pulley. A flange a¹ is placed
between the grooves to prevent one rope mounting over into the other groove.
The grooved driving pulley A is mounted upon a conical friction bush B which
is keyed or fixed to the shaft C. The pulley A rotates freely upon the shaft C or
upon a bush c thereon and is capable of lateral movement to a limited extent, and
the pulley A may engage with the friction bush B either at its periphery or at the
boss.
I at present prefer the construction and arrangement shown in Figs. 1 and 2
the friction bush or cone B being keyed to the shaft C and the grooved pulley A
mounted over it to engage with the periphery thereof. The pulley A rotates on
the shaft and is capable of a lateral movement to a limited extent to permit of it
being thrown into and out of gear with the friction bush or cone B.
The boss of the pulley A. is formed with a groove d and a clip D in the form of
a fork or band engages therewith to move the pulley A to one side or the other.
Very little movement of the pulley is required to cause it to engage or disengage
with the friction bush B.
The fork D is formed with a bell crank lever E pivoted at e by which the pulley
is moved to one side or other as required. The lever E is pivoted on an arm f of
the bracket F and is moved backwards and forwards by a screw G to the end of
which it is pivoted the screw passing through the upper end of the bracket F which
is provided with a screw thread to receive it.
In an alternative arrangement the friction bush B may be capable of being
moved along a feather or key fixed in the shaft to engage and disengage with the
pulley A.
Referring to Figs. 3 and 4 an alternative arrangement for moving the grooved
pulley A into and out of contact with friction bush B. The fork D is operated
by a starting and stopping lever H extending to the front of the machine or to any
other convenient position. The lever H is connected to the pivoted fork D and
bell crank lever E by the cranked lever E¹ and connecting rod e¹ provided with a
screwed coupling ell for regulating or adjusting the position of the fork D.
Referring to Figs. 5 and 6 a modified arrangement of the pulley and bush are
shown the pulley A engaging with the bush B both at the boss and the periphery.
In Fig. 5 the boss of the bush B is for a portion of its length made cylindrical to
form the sleeve c and the boss of the pulley A, for a certain distance corresponding
thereto is cylindrical and rotates thereon. The conical part of one boss engaging
with that of the other when the pulley is brought into contact with the friction
bush B. In Fig. 6 the bush B is made with a conical boss with which a conical
part of the boss of the pulley A engages while rotating on the shaft.
In Figs. 7 and 8 the modified forms of sleeves are shown upon which the
pulleys A rotate.

page_text: Flaving now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. Driving mechanism for carding engines (or other machines) constructed and
arranged substantially as described and shown.
2. In apparatus for driving carding engines (or other machines) the combination
with a grooved rope pulley rotating loosely around the driving shaft of a conical
friction bush with which the pulley may be thrown into or out of gear by a forked
lever or other device substantially as described.
