Improvements in or relating to Self-acting Mules and Twiners.
We, MARTIN MUSGRAVE, of Tudor House, Chorley New Road, Cotton Spinner,
JAMES WALSH, of 457, Chorley Old Road, Smithills, Overlooker, and THOMAS
KITCHEN, of 429, Chorley Old Road, Manager, all of Bolton, in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention refers to improvements in or relating to self-acting mules and
twiners employed for spinning cotton, silk, worsted, woollen, and other fibrous
materials and substances and consists in means to ensure of even and uniforni
winding, prevent snicks, snarls, and waste, at the same time producing steady
winding during the inward run of the mule carriage during the formation of
the cop; prevents undue strain on and the breaking of the winding chain, also
backing-off too far, and dispenses with the ordinary winding catch and winding
catch wheel, the latter being substituted by catch-box wheels or by a friction
gun-lever with an incline
clutch. This we carry into effect by providing the
which works in conjunction with a forked lever mounted on a pin or centre
supported from any convenient position. To the fulcrum end of the aforesaid
forked lever is attached another forked lever which slides out of gear
a catch-box or a friction clutch mounted on the tin cylinder shaft; the reverse
action being effected by means of a spiral spring connected at one end to the
forked lever and at the other end to any fixed position.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of so much of a self-actor mule as is necessary
to illustrate our said invention. Fig. 2 a plan of Fig. 1. Fig. 3 an end eleva-
tion of Fig, 2, and Fig. 4 a front elevation of friction clutch mounted on tin
cylinder shaft.
In all the figures the same letters are employed to indicate corresponding parts.
A is the ordinary "gun-lever" employed in self-acting mules and twiners;
B incline; C forked lever; D catch-box; E tin cylinder shaft, and G the wind-
ing drum.
The ordinary "gun-lever" A employed in self-acting mules and twiners is
mounted in the usual manner and is provided with the incline B secured by the
set screws H. The incline B works in conjunction with the forked lever C
mounted on the pin or centre I. To the fulcrum end of the aforesaid forked
lever C is attached the lever J by the pin or centre I. The lever J is provided
with the boss in which is loosely mounted the fork L which fits in the neck M
on the boss N of the sliding portion of the catch-box D. The boss N extends
beyond the neck M sufficiently long to admit of the spur wheel O being mounted
thereon. The spur wheel O gears with the spur wheel l' on the winding drum G.
The lever Jis pivoted to the fixing R by the pin or centre S. The fixing R
is secured by the bolt T to the framing U of the mule-head" or to any other
convenient or desired part. When the ordinary" gun-lever "A is moved in the
direction indicated by the arrow
the incline B operates in the forked
end of the lever C and slides the sanie, also the lever J and fork L by which
the sliding portion of the catch-box D will be moved out of gear with the fixed
portion of the said catch-box D. The fixed portion of the catch-box D is pro-
vided with the boss W by which it is secured to the shaft E by the key X or
its equivalent such as-a set screw. When the ordinary "gun-lever" A makes
the reverse motion to that indicated by the arrow shown in Fig. 2 the
sliding portion of the catch-box D) is placed in gear with the fixed portion of the
said catch-box by the action of the spiral spring Y immediately the forked end of
the lever C is released from the incline B secured to the ordinary "gun-lever" A.
The spiral spring Y is secured to the lever C by the arm or projection and the
nuts a on the screwed end b; the other end of the said spiral spring being pro-
vided with the screwed end f and the nut g, by which it is coupled to the fix-
ing Z mounted on the mule carriage or secured to any convenient part of the
mule. In lieu of the catch-box D with the serrated teeth e the friction clutch
shown in Fig. 4 may be employed. The sliding portion of the friction clutch ])
is provided with the neck M on the boss N in which fits the fork L mounted
in the boss K of the lever J as shown in Figs. 1, 2 and 3. To increase the
gripping or driving power of the clutch-box 1) the face of the fixed portion is
covered with a casing t of leather; the latter being secured thereto in any con
venient manner.
We would have it understood that we do not confine ourselves
to the precise details and configuration of the parts we have shown and described
as the same may be varied or modified without departing from the principle of
our said invention as they may be constructed and arranged so as to meet the
various kinds of self-acting mules and twiners employed.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
The general arrangement construction and combination of parts composing our
improvements in or relating to self-acting mules and twiners consisting of the
pivoted lever J with the boss K in which is mounted the fork L fitting the
neck M on the boss N of the sliding portion of the catch-box or friction clutch D;
the lever J being connected to the fork lever C by the pin or centre I: the
lever C is operated to disengage the catch-box or friction clutch D by the sliding
action of the incline B secured to the ordinary gun-lever" A; the reverse
action being effected by the spiral spring Y immediately the fork end of the
lever C is released from the incline B by the backward movement of the ordinary
gun-lever" A, the whole being connected applied and operating substantially
as described and as illustrated in the drawings.
