Improvements in Spinning Mules.
EDWARD HALL Cotton Dealer Whitehead Street Oldham do hereby declare
the nature of this invention to be as follows:-
The application of an automatic shortening motion attached to the strap pulling
off rod of spinning mules for the purpose of regulating the twist, preventing snarls
releiving the friction and saving steam power and other purposes.
The object of the invention is to pull the strap onto the loose pulley a little
sooner every draw of the mule untill the cop is full. This is accomplished by
gradually shortening the strap pulling off rod so that the carriage of the mule
strikes the lever earlier.
1. This invention consists of a streight rack of about 12 inches long inserted in
the strap releiving rod with two catches.
2. In place of the stap releiving lever being as at present fixed to the floor, it is
attached to a slide bracket, and this last named bracket is attached to the shaper
rod which travels inward about nine inches in the course of every doffing.
3. There is also a balance weight fixed to the strap releiving lever to bring it
back to its place after having releived the strap.
The object of this invention is to releive the strap a fraction earlier every draw
of the mule from the commencement of the cop untill the cop is full. The
revolutions of the mill spindle are so quick and having to be stopped and reversed
for backing off at the end of every draw of the mule by friction pulleys; as the
cop increases in size and weight the friction cannot stop and reverse with a full
cop as soon as at the commencement of the cop when the spindles are empty,
concequently there is more twist in the yarn at the full cop then at the commence-
ment of the cop, which causes snarles and spoiles the yarn also making the frictions
which stop and reverse the mule so hot they cause fires.
This invention overcomes theese dificuties by releiving the strap a little earlier
every draw of the mule from the commencement of the cop untill the cop is full ;
and so compensating for the gradual increase of the weight of the cop on the
spindle, untill the cop is full and then commences afresh. It is attached to the
shaper rod & with it has to be set back to its place at the commencement of every
doffing.

I EDWARD HALL of Whitehead Street, Oldham Cotton Dealer 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:-
The application of an automatic shortening motion attached to the strap releiving
rod of spinning mules for the purpose of regulating the twist from the bottom of

page_text: the cop to the full cop, preventing snarls, releiving the friction, saving steam
power, & other purposes.
The object of this invention is to releive the strap from the twist pulley a little
earlier, every draw of the mule, from the bottom of the cop, to the full cop, & so
compensate for the weight of the cop on the spindle, as it increases in size until it
is full.
In order that my invention may be more readily understood, I proceed to
describe the same fully, with reference to the accompanying drawing, in which
Figure I is a front elevation.
A, is a lever by which the strap is releived from the twist pulley each time the
carriage of the mule passes over it. This lever A, when it has releived the strap
is brought back & rests on the right hand top corner of the slide bracket B. This
is accomplished by the weight marked G, cast on lever A. This motion causes
the slide rack F to shorten, as the slide bracket B moves inward from left to right.
B, is a slide bracket to which the lever is attached by means of a stud screwed to
the bracket, the lever working on the stud.
This slide bracket works in a slide marked C which is screwed to the floor.
D is a wrought iron connecting bracket 1 by inch in the shape of a swan's neck,
& connects the slide bracket B, to the shaper rod. This shaper rod to which the
slide bracket B is connected travels inward about 10 inches in the course of every
doffing. E is the strap releiving rod which is connected with the lever A, at No. 1
& is connected with the strap guider at the other end No. 2. F, is a slide
rack inserted in the strap releiving rod, which, as the slide bracket B, along with
the lever A, travels inward, shortens the strap releiving rod, .thus causing the
carriage of the mule as it passes over the lever to strike it earlier, & so releive the
strap earlier.
Figure 2 shows how the slide bracket is connected with the shaper rod.
D is the connecting bracket which is attached to the shaper rod at H. I, are
two nogs slid on the shaper rod with set screws to secure the connecting
bracket.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what
I claim is :-
1. The slide rack with two catches inserted in the strap releiving rod.
2. The strap releiving lever weighted to bring it to its place after having
releived the strap as shown in Figure 1, A.
3. The application of the slide & slide bracket marked B & C.
4. The application of a connecting bracket connecting the slide bracket to the
shaper rod marked D.
