PROVISIONAL SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
I, ROBERT CLEGG, of Soho Iron Works, Oldham, in the County of Lancaster,
Foreman of Mule Room, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in self acting mules and twiners, and the
object of my invention is to improve the mode of driving the rim shaft from the
counter shaft.
I accomplish this object by employing a single pair of wide pulleys one fast and
the other loose on the rim shaft and a pair of belts transmitting motion from the
counter shaft in combination with a pair of strap forks one for each beit mounted
on a single shipper lever or otherwise conveniently arranged so as to shift the pair
of belts simultaneously.
The strap forks may be moved to and fro at the required times by any suitable
arrangement of mechanism, as for example, in one direction by a rotating cam
driven from the rim shaft and in the other by a spring or suspended weight.

COMPLETE SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
1, ROBERT CLEGG, of Soho Iron Works, Oldham, in the County of Lancaster,
Foreman of Mule Room, 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:-
My invention relates to improvements in self acting mules and twiners, and the
object of my invention is to improve the mode of driving the rim shaft from the
counter shaft.
I accomplish this object by employing a single pair of wide pulleys one fast and
the other loose on the rim shaft and a pair of belts transmitting motion from the
counter shaft in combination with a pair of strap forks one for each belt mounted
on a single shipper lever or otherwise conveniently arranged so as to shift the
pair of belts simultaneously.
The strap forks may be moved to and fro at the required times by any suitable
arrangement of mechanism, as for example, in one direction by a rotating cam
driven from the rim shaft and in the other by a spring or suspended weight.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is an elevation and Fig. 2 a plan of my improved arrangement of
mechanism for driving the rim shaft from the counter shaft.
In these views, a designates the rim shaft, h the wide fast pulley and c the
wide loose pulley; d d the pair of belts which transmit motion from the counter
shaft; ee the pair of strap forks, mounted on the single shipper lever f, which is
fixed on the shaft g upon which is also fixed the arm ; is the cam upon the
cam shaft ; which is driven by gearing not shown from the rim shaft a.
In operation, the strap forks ee are moved in one direction by the rotating cam i
which acts upon the arm h, shaft g, and shipper lever and so moves the pair of
D

page_text: belts dd from the loose pulley e to the fast pulley 6 whereby the rim shaft a
receives motion, until the wide portion of the cam i leaves the arm h, when a
spring or suspended weight, not shown, comes into action and draws back the
shipper lever and forks e e thereby shifting the pair of belts from the fast
pulley 6 to the loose pulley c.
I would have it clearly understood that the essential feature of my invention
consists in the use of a pair of belts and a single pair of wide pulleys one fast and
one loose upon the rim shaft in combination with belt shifting mechanism arranged
to move the pair of belts simultaneously from one wide pulley to the other wide
pulley as required, and that the belt shifting mechanism shown and described,
although a convenient one for the purpose, may be varied or modified to suit
different requirements as found necessary or desirable.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a self acting mule or twiner the combination with a pair of wide pulleys
one fast and one loose on the rim shaft, of a pair of belts transmitting motion from
the counter shaft and mechanism for shifting the said belts simultaneously from
one pulley on the rim shaft to the other as required.
2. The combination with the rim shaft a, pair of pulleys bc, and pair of belts
dd, of the pair of strap forks e e moved simultaneously in one direction by the
rotating cam i and in the other by a spring or suspended weight to shift the pair
of belts from one pulley to the other as required, all substantially as herein shown
and described.
