THOMAS ATHERTON TRUSLOVE, 221, Abbey Hills Road, Oldham, Lancashire,
Cotton Spinner, do hereby declare the nature of this invention to be as follows:-
The apparatus is for the prevention of snarls in cotton yarns.
The strapping motion on a spinning mule or jenny requires adjusting by the
spinner and unless he turns the quadrant screw slack curly yarn will wind on the
spindles. My invention is to make the strapping motion self adjusting requiring
no attention by the spinner and therefore preventing snarls-(double curly yarn).
The apparatus is composed of three brackets one 9 in. long with slot 4 in. with
bolt hole at top 2 bracket is 4 in. long aame length slot and bolt hole No. 3 is
round in. thick hole at top and bottom. Length 6 in. The 9 in. bracket must
be bolted through slot on to the upright strapping motion bracket on winding
faller shaft. This addition gives the strapping motion a greater sweep.
These conditions require a longer strapping chain but instead a 6 in. long in.
wide bracket or round rod is riveted to the chain which is better and carried to
top of added bracket and to work loose on a stud which is fastened through bolt
hole at top of added bracket.
Then a bracket 4 in. long 1 in. wide with slot for adjustment must be bolted
horiszontally and through slot of added bracket. This horizontal bracket must
have a stud at one end which must press against strapping chain rod when the mule
is winding yarn on spindles.

Improvements in Spinning Mules and Jennies.
THOMAS ATHERTON TRUSLOVE, 221, Abbey Hills Road, Oldham, Lancashire,
Cotton Spinner, 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 invention relates to the strapping motion which in its present form requires
attention by the spinner for a considerable time after the mule has doffed; but
by bolting a 9 in. bracket through a slot 4 in. long (for extending if required) and
through the stud-hole at top of present upright bracket on winding-
faller shaft and by riveting a rod 6 in. long to the end of strapping chain and
carrying to the top of 9 in. bracket to work loose in a stud-hole at the top and by
...031

page_text: bolting a 5 in. bracket (with slot for adjustment) horizontaly through slot of 9 in.
bracket with stud at one end to press against rod, the strapping motion becomes
self adjusting requiring no attention by the spinner at all. The cotton spinning
mule and cotton spinning jenny are one and the same machine.
What is discribed as a mule in one town is discribed as a jenny in another.
The strapping motion on the spinning mule and jenny is a part of the machine
that regulates the yarn when winding on the spindles. But in its present form
it requires the attention of the spinner for a considerable time after each mule
and jenny has been doffed and if he is inattentive slack yarn (these are called
snarls) will wind on the spindles.
My invention is to make this part of the machine self adjusting and so pre-
venting slack yarn or snarls.
To accomplish this object I find that a greater sweep is required by the upright
strapping motion bracket D on the winding faller shaft. This bracket has a
stud-hole C at the top to carry the strapping chain F. To gain the object the
stud is dispensed with, and a 9 in. bracket A is bolted on through this stud-hole C.
This bracket A has a slot B 4 in. long for extension this gives a greater sweep to
the strapping motion and the longer these combined brackets are made which
can be done by the extending slot B the more it becomes self adjusting.
Of course the strapping chain F will be too short by this alteration and instead
of lengthening the strapping chain F a rod E 6 in. long is rivited to it and carried
to the top of the 9 in. bracket A where it must be cottered on and to work loose.
The strapping chain F is connected with what is known as the strapping lever.
This lever should only be in gear when the mule and jenny is winding, but in
some cases whero the chain F is too long it allows the lever to drop in gear when
the mule and jenny is not winding.
So a bracket T5 in. long is bolted horizontaly through the slot B of the 9 in.
vertical bracket A.
This bracket P has a slot 3 in. long for adjustment also a stud at one end to
press against the rod E when the mulo and jenny is not winding.
This will keep the strapping lever out of gear when the mule and jenny is
spinning (not winding).
Having now particularly discribed and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The 9 in. bracket A which when bolted on the present strapping motion
bracket D will lengthen it giving it a greater sweep of from 3 in. to seven ins.
2. The rod E 6 in. for lengthening the strapping chain. F.
3. The 5 in. bracket P which will keep the strapping lover out of gear when
required.
