PROVISIONAL SPECIFICATION.
Improvement in Mules for Spinning.
LUKE RUSHWORTH, 218 Edge Lane, Droylsden, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
It is well known, that considerable trouble is often caused, by the unsatisfactory
manner, in which the majority of nose pigs, or nosing motions, act.
Also, by the frequent breaking of quadrant bands.
Now this invention is designed to reduce the attention required to a minimum,
and to reduce the strain on the quadrant bands by about one half, and consists of a
scroll pulley, or a scroll and pulley combined, which works on a stud, secured to
the side of the headstock frame, or other convenient position, about midway between
the roller beam, an the outhead. The said scroll pulley has a stop cast on it, or a
stud, pin, or other contrivance, in order to prevent the said scroll pulley making
more than one revolution.
To one part of the aforesaid scroll pulley, is secured, one end of the winding
chain, the other end of the winding chain, passes over a small pulley, attached to
the nut of the quadrant, & is secured to the winding drum in the usual manner.
To another part of the scroll pulley, is attached a short chain, and to this chain
a rod, which passes toward the back of the headstock, in the direction in which the
carriage travels, on the said rod, there is an adjustable finger, or peg, at right
angles to it.
The winding chain, and the short chain, which is connected to the said rod, are
so arrainged, that when one chain is winding on, the scroll pulley, the other chain
is winding off. To the front of the carriage frame, is an upright lever, free to
move in the direction in which the carriage moves.
Immediately in front of the said lever, there is a slide bar, with an inclined slide
block, in the form of a wedge, with the point downwards. The said slide block is
raised, and lowered, by means of a chain, connected to a lever, pulley, or quadrant,
on the winding faller. The faces of the slide block, and the upright lever, nearest
to each other, may be toothed, or serrated, in order to prevent the said slide block
from slipping.
The action is as follows, When the carriage runs in to the beam, the upright lever,
hereinbefore mentioned, comes in contact with the finger, or peg, on the rod before
described, "a short distance from the beam," it winds off a portion of the short
chain, connected to the said rod, and consequently winds on a portion of the winding
chain. The winding chain becoming shortened by this means, in turn, tightens the
yarn on the nose of the cop.
The slide bar herein before mentioned, is raised, and lowered, in proportion to
the build of the cop. The nearer the winding faller gets to the top of the spindle,
the lower the slide block falls, consequently, tightening the yarn most on the top
of the cop, where a hard point or nose is most required.
By this invention, the nut or (strapping motion) on the quadrant, will only
require to be wound half way up, consequently, reducing the strain on the quadrant
bands, by one half.
Dated this 16th day of April 1892.

LUKE RUSHWORTH 218 Edge Lane Droylsden near Manchester Lancashire
Engineer 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 :-
It consists of a movable inclined plate working in an horizontal direction in a
suitable bracket fixed or secured to the headstock frame, there is also a stud fixed
to a slide bar which slides in a vertical direction inside the said bracket & is raised
& lowered by the inclined plate. To this stud I connect one end of the winding
chain, I pass the said chain over a pulley or bowl connected to the nut of the
quadrant, & connect it to the winding drum in the usual manner. The inclined plate
before mentioned is worked backward & forward, by means of rods levers cranks
& the like connected to the builder motion.
The bracket before mentioned that carries the inclined plate and the stud, is so
arranged as to work inward & outward by means of a screw & handle, so that in
case the chain locks, it can be slackened without altering position of the quadrant
nut.
The action is as follows, As the cop builder motion works back it acts on the rods
levers & the like gradually drawing the inclined into the bracket thereby raising
the stud & tightening the winding chain consequently winding the yarn tighter on
the nose of the cop.
By the winding chain being fixed to the bracket & passing over the pulley on
quadrant nut, it pays double the amount of chain, than it would do if fixed in the
ordinary manner.
It will be seen by this invention that the quadrant nut will only require winding
half way up, dispensing with the upper portion of quadrant, also reducing the strain
on the quadrant bands by one half.
In order that the foregoing may be better understood, I send herewith a sheet
of drawing of which Fig. 1 is a side view of the apparatus. a indicates the inclined
plate. 6 the bracket. ca stud connected to a slide which works vertically inside the
bracket b. d is a pulley connected to the quadrant nut, over which the winding
chain works. e is the quadrant, the winding chain, 9 the carriage, h the winding
drum. the rod which connects the inclined plate with the cop builder motion.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare what I
claim is
1st. Attaching the winding chain to headstock side & lifting same by means of
an inclined plate connected to the cop builder by means of rods levers & the like
substantially as described and shown hereinbefore and in the accompanying drawing,
for the purposes set forth.
2. Working winding chain over pulley connected to quadrant nut, & to the
winding drum, substantially as described and shown herein before and in the accom-
panying drawing for the purposes set forth.
3. In moving winding chain "where it is fastened to headstock frame" outwards
& inwards by means of a screw & handle so that in case the chain locks it can be
slackened without altering position of quadrant nut, substantially as described and
shown hereinbefore and in the accompanying drawing for the purposes set forth.
