PROVISIONAL SPECIFICATION.
Improvements in Mules for Spinning.
We, JOHN BARLOW of 55 Walton Terrace, Rishton Lane, Cotton Spinner, and
JOHN BOOTH of Marsden Road Ironworks, Machinist, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:
-
This invention relates to improvements in mules for spinning cotton and other
fibrous substances, and is designed to prevent or minimise the breaking of the yarn
when backing-off and winding are being performed, also to prevent loose waste being
wound onto the cop.
In carrying out our invention we mount on or attach to the underfaller rod, or to
the ordinary salmon-head" lever or its equivalent-mounted on the underside of the
mule carriage and connected to the underfaller rod by a quadrant, or a lever, rod,
hand, strap, or chain-a pivoted curved lever in any convenient manner. The front
or outer end of this lever is provided with a strap, band, chain, rod, or bearer attached
to the mule carriage by adjustable means to regulate the position of the same to com-
pensate for varying degrees of tension required. In case the curved lever is attached
direct to the faller-rod, or a lever on the same, it is supported by an adjustable fixing
or its equivalent supported from the framework of the mule carriage, or from the head-
stock or other framework, travelling or sliding on the same according to the movements
of the mule carriage.
When the mule carriage has almost completed its outward run the outer end of the
curved lever slides on an adjustable pin secured to an adjustable fixing mounted either
on the headstock, mule room floor, or otherwise. When the adjustable fixing is
mounted on the mule room floor it is constructed so as to protect the attendants at the
mule from accident, at the same time providing a fence to prevent the lever operating
therewith being interfered with. The major or other portion of the length of the
curved lever slides over the adjustable pin, which causes the curved lover to vibrate on
the said pin and eases or reduces the weight of the same and the "salmon-head" or
other lever from the underfaller wire, thereby producing a gradual yielding motion to
the latter, which operates in such a manner as to prevent or minimise the breaking of
the yarn when the underfaller wire rises when backing-off and winding commences.
When the mule carriage commences to make an inward run the action of the curved
lever is gradually decreased, which allows the underfaller wire to operate in the usual
manner. The end of the curved lever is provided with a suitable preparation to
receive weights to compensate for varying counts being spun.

Improvements in Mules for Spinning.
We, JOHN BARLOW of 55 Walton Terrace, Rishton Lane, Cotton Spinner, and
JOHN BOOTH of Marsden Road Iron Works, Machinist, both of Bolton in the County
of Lancaster. do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to improvements in mules for spinning cotton and other
fibrous substances, and is designed to prevent or minimise the breaking of the yarn
when backing-off and winding are being performed, also to prevent loose waste being
wound onto the con.

page_text: In carrying out our invention we mount on or attach to the underfaller rod, or to
the ordinary salmon-head" lover or its equivalent-mounted on the underside of the
mule earringe and connected to the underfaller rod by a quadrant, or a lover, rod,
band, strap, or chain-a pivoted curved lever in any convenient manner. The front
or outer end of this lever is provided with a strap, band, chain, rod, or bearor attached
to the mule carriage by adjustable means to regulate the position of the same to coin-
pensate for varying degrees of tension require]. In case the curved lever is attached
direct to the fuller-rol, or a lever on the same, it is supported by an adjustable fixing
or its equivalent supported from the framework of the mule carriage, or from the
headstock or other framework, travelling or sliding on the same necording to the
movements of the mule carriage.
When the mule carriage has almost completed its outward run the outer end of the
curved lever slides on an adjustable pin secured to an adjustable fixing mounted either
on the headstock, mule room floor, or otherwise. When the adjustable fixing is
mounted on the mule room floor it is constructed so as to protect the attendants at
the mule from accident, at the same time providing a fence to prevent the lever
operating therewith being interfered with. The major or other portion of the length
of the curved lever slides over the adjustable pin, which causes the curved lover to
vibrate on the said pin and eases or reduces the weight of the same and the "salmon-
head or other lever from the underfaller wire, thereby producing a gradual yielding
motion to the latter, which operates in such a manner as to prevent or minimise the
breaking of the yarn when the underfäller wire rises when backing-off an-1 winding
commences.
When the mule carriage commences to make an inward run the action of the
curved lever is gradually decreased, which allows the underfaller wire to operate in
the usual manner. The end of the curved lever is provided with a suitable prepara-
tion to receive weights to compensate for varying counts being spun.
Fig. 1, sheet 1, of the accompanying drawings is a part side elevation of so much of
a mule carriage and headstock with our improvements applied as is necessary to
illustrato our invention, and Fig. 2 is a plan of same.
A is the mulo carriage; B the headstock; ('the underfaller rod; D the underfallor
wire; E the sickle for carrying the underfaller 1); F the faller rod; († the fuller
wiro; H the sickle for carrying the fullor wire G, and I the spindles on which the
cops J'' are spun.
To the underfaller rod is attached the lever J as shown or in any other con-
venient manner. The outer end of the lever J is fitted with the centre K, on which
is mounted the curved lover L. This latter lover slides on the upper side of the
headstock B by the travelling action of the mule carriage A. The curved lever L
is provided with the centre or pin M to receive the weights O to allow of the action
of the same heing altered to the demands or requirements according to the counts of
yarn being spun. On the headstock B is mounted the incline N secured theroto by
the bracket P and bolts Q. When the male carriage A has almost completed its
outward run the curved lever L slides on the incline N, and assumes the position
shown in dotted lines in Fig. 1, during which the faller and underfaller wires are in
their usual positions when spinning is being performed. I will be seen on examining
the drawings that when the curved lover L is in this position that the major portion
of its length extends over the end of the incline N, which has a tendency to raise
tha lever it is pivoted to. Immediately spinning is completed each draw the
faller wire G and the underfaller wire D assume the positions shown in Fig. 3 to
effect winding the yarn on the cops J when the mule carriage A makes the inward
run. When the underfaller wire D rises and lifts the yarn T as shown in Fig. 3,
by the action of the "salmon-head" levers and other mechanism employed for the
purpose, the strain on the yarn is considerable, causing the yarn to be broken and
loose waste to be wound on the cops when backing-off and winding commences.
Many attempts have been made to remove these evils by placing inclines and other
equivalents underneath the underfaller levers; but, in consequence of the full weight
of the levers boing put upon the yarn instantly, when the levers leave contact with

page_text: the inclines and other mechanism employed, they often cause the very evils they
are intended to remove. These defects are to a very great extent removed or
considerably minimised by the action of the curved lever L, which reduces the
sudden strain of the underfaller wire D from the yarn. When the mule carriage A
commences to make an inward run the curved lever L slides backwards on the top
of the incline N and gradually looses its effect on the underfaller wire D, and
allows the latter to operate in the usual manner by the ordinary appliances. This
relieving motion eases the weight on the under faller wire to the extent required for
either course or fine counts of yarn, and by its gradual yielding action allows the
weight to go on in such a manner that (even with oxtra weight added for the purpose
of making harder cops, and increasing the weight of a "set") there is considerably
less breaking of the yarn, and consequently less loose waste made.
Fig. 4 is a side elevation of our invention when applied to mules where it is incon-
venient for the curved lever to slide on the headstock, and Fig. 5 is a plan of
same.
In this arrangement the curved lever L is provided with the pin R to carry the
same in position on the bracket S, attached to the mule carriage A, when not in
contact with the pin N-the equivalent for the incline N in Figs. 1 and 2. The
bearing surface of the bracket $ is sufficiently long to allow the lever L to move
according to the requirements of the underfaller rod when changing for spinning.
On the outer end of the headstock B is fixed the bracket U by the bolts V. To the
bracket U is fixed the pin N on which the curved lever L operates as shown in
dotted lines; the action of the same on the underfaller wire being similar in every
respect to that described in Figs. 1 to 3 inclusive.
Fig. 6, sheet 2, is a side elevation of our invention when coupled to the "salmon-
head lever, and Fig. 7 is a plan of same.
"
The salmon-head" lever W is attached to the mule carriage A in the usual
manner by the fixing X and pin Y, and is coupled to the underfaller rod by the
strap Zand quadrant A' or their equivalents according to the class or make of mule.
To the "salmon-bend lever W is pivoted the curved lever L by the centre K.
The front or outer end of the curved lever L is held in position by the strap, band,
or chain B attached to the projection C and the front of the mule carriage A by
the bracket D'. The strap, band, or chain B allows of the curved lever L being
raised as shown in dotted lines without interfering with its action. On the mule room
floor is fixed the bracket E' carrying the adjustable fixing with the pin N. The
bracket E is covered by the casing H¹ to prevent the attendents feet coming in con-
tact with the sharp corners or other parts of the same. When the mule carriage A
bas almost completed an outward run the curved end of the lever I slides on the
pin N, as shown in dotted lines in Fig. 6. As soon as the underfaller rod C is
operated on the completion of the outward run of the mule carriage the underfaller
wire D rises as shown; the action of which is minimised by the major portion of the
curved lever L vibrating on the pin N and easing the weight of the "salmon-head"
lever W from the same, thus reducing the strain of the underfaller wire D from the
yarn T when backing-off and winding commences. When the mule carriage A com-
mences to make an inward run the curved lever L slides back over the pin N, and
the weight of the "salmon-head" lever W is gradually put on the yarn T, which
then operates in the usual manner during the remainder of its inward run to complete
winding.
In case the "salmon-head "levers W and their connections are unequally disposed
on the mule carriage A we mount at uniform distances the levers W₁ shown in
Figs. 8 and 9. In this arrangement the levers Ware connected to the underfaller
rod by the levers S¹ and rods M. The rods M' are made in two parts each-one
with the socket O' and the other with the slot V₁, and jointed by the bolt R'-to
compensate for irregularities in the mule room floor. The operation of this arrange-
ment is precisely similar to that described in Figs. 6 and 7.

page_text: Having thus stated the nature of our invention and described the mode of per-
forming the same we would have it understood that we do not confine ourselves to
the precise details or configuration of the parts we have shown and described as tho
some may be varied or modified without departing from the principle of our inven-
tion according to the class of mule to which it may be applied, but what we claim
and desire to be secured by Letters patent is :-
―
1. In males for spinning cotton and other fibrous substances automatically easing
or relieving the yarn from sudden strain when the undorfuller changes to allow
backing-off and the winding of the yarn on the cops being performed, sulistantially as
described for the purposo specified.
2. For automatically easing or relieving the yarns from sudden strain when the
underfaller wire changes to allow lacking-off and the winding of the yarn on the cops
being performed the use of the lever L. attached to the underfaller rod or its adjuncts
in combination with the incline N or its equivalent applied and operating in such a
manner that the lever I gradually looses its effect on the under faller wiro as the mule
carringe moves inwardly, substantially as described and as shown on the drawings.
8. The several constructions combinations and arrangements of parts embodying
our improvements in automatic apparatus for easing or relieving the yarn from
sudden strain when the underfaller wire changes to allow barking-off and winding
being performed, substantially as and for the purposes herein described and as
illustrated by the accompanying drawings.
