An Apparatus applicable to Spinning Mules.
We ROBERT TURNER of 22 Sykes Street Mule Overlooker and JOHN LEES
of Milnrow Road Mill Manager both of Rochdale and County of Lancaster do
hereby declare the nature of this invention to be as follows:-
Our invention relates to an apparatus for avoiding the breaking of the yarn
during the process of spinning, and is applied to the winding faller shaft or in
connection with the winding faller, which faller is well known, and the said
invention is particularly adapted for spinning mules spinning coarse counts as in
such machines the winding faller is heavily weighted.
This invention admits of the application of increased weight to the faller, as it is
well known that by the addition of weight to or on the faller, the cops are firmly
wound or formed "solid" also by its use the said winding faller can only fall or be
depressed at the proper periods, that is, when winding,-
-as it is a common
occurrence for the faller to drop when the same is heavily weighted, and often the
threads are from. this cause broken, now this invention is designed with a view to
this evil and is adapted to obviate such occurrence and consequent damage.
We accomplish our object by the following means.
We hang or depend from a bracket provided on the winding faller shaft a lever
which is allowed to freely swing on a stud attached thereto, its lower extremity being
"hook shape" which extremity passes through a slotted piece or guide provided
conveniently on the carriage of the mule.
The lever being so hung or depended that the "hook shaped
end shall press
against or impinge on a side of the slotted piece so that when in its normal position
the lever is interlocked with the slotted piece or guide.
33
When the mule carriage has run out to or nearly to its full extent the lower
end of the depending lever engages with a fixed piece or stud provided at any
suitable part, which engagement causes the lever to become unlocked, thus the
weight applied to the winding faller shaft is free to control or depress the
winding faller. When the carriage has run in, and the spindles finished winding,
or when the carriage has run in to its full extent, the position of the faller is
reversed or is caused to rise-the ordinary action-the depending lever then
interlocks with the slotted piece or guide, consequently the faller is prevented
from falling at an improper period, that is, during the "stretch" of the yarn
or run out of the carriage, as the lever is not unlocked or released from the
guide until the carriage has run out to its full extent as before stated, thus the
faller is prevented from falling and the breaking of the yarn is obviated..

An Apparatus applicable to Spinning Mules.
We ROBERT TURNER of 22 Sykes Street Mule Overlooker and JOHN LEES
of Milnrow Road Mill Manager both of Rochdale in the County of Lancaster,
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 :-
Our invention relates to an apparatus or arrangement of mechanism for avoiding.
the breakage of yarn during the process of spinning, which invention is to be
applied to the winding or faller shaft in connection with the winding faller wire.
The said invention is more particularly adapted for mules spinning coarse counts,
as it is well known, that in such machines when the winding faller is heavily
weighted the said faller is liable to depress or fall at improper periods, that is, when
the mule carriage is running out, consequently upon the happening of such an event
damage or breakage of the yarn occurs.
Our invention is designed for the purpose of obviating this defect, so that the
winding faller wire shall fall or depress at proper periods only, that is, during the
winding operation.
This invention admits of the application or employment of a faller weighted to
any suitable extent accordingly as may be desired and according to coarseness of
counts being spun, as it well known, that the advantage of a heavy faller, is that the
cops may be firmly wound and formed "solid." The main objections at the present
time as to the use of heavily weighted fallers is the common occurrence before named,
the dropping or falling of the wire at improper periods.
We accomplish our object by the following means.
We hang or depend from a bracket provided on the winding fuller shaft, a lever
which is allowed to freely swing on a stud attached thereto, its lower extremity
being hook shaped or being provided with a projecting part, which extremity
passes through a slotted piece or guide conveniently provided on the carriage of
the mule.
The lever being so hung or depended, that the hook or projecting part of the
lever shall press against or impinge on a side of the slotted piece, so that when the
lever is in its normal position, the lever is interlocked with the slotted piece, plate,
or guide.
When the mule carriage has run out or nearly to its full extent or limit of the
carriage race; the lower end of the depending lever is then caused to engage with a
fixed piece or bracket provided at any suitable part in the carriage race, which
engagement causes the lever to become unlocked, then the weight applied to, or the
ordinary mechanism operating the winding faller shaft, is then free to control or
depress the faller. When the carriage has run in and the winding conpleted, the
position of the faller being reversed or caused to rise-the ordinary action or
movement, the depending lever falling then interlocks with the slotted piece or
guide or may be assisted or passed to this interlocked position by a suitable weight,
spring, or other equivalent means. The faller is thus prevented from becoming
depressed or falling at an improper time, that is, during the stretch of the yarn or
run out of the carriage, as the lever is not unlocked or released from the guide or
plate until the carriage has run to its full extent and actuated as before named.
In order that our invention may be better understood we have reference to the
accompanying sheet of drawings in which like letters of reference indicate like parts
throughout the figures therein shewn.
Figure 1. represents our invention in elevation.
Figure 2 represents a front view of Figure 1.
The lever a. is hung or depended from the stud b. of the bracket c. which bracket
is provided on the winding or faller shaft d. The lever a. passes downwards and

page_text: through a slot e² in the piece or guide e. The said lever being, or may be so hung
or depended from the stud b, in order that the hook extremity or projection of may
engage with a side of the slot e³ so as to pass to the part at e¹ of the said slot, con-
sequently when in this position, the lever becomes interlocked with the slotted plate
or piece e, and remains in such position until released therefrom by the means as
hereinafter more particularly described; but in order to assist or accelerate the
interlocking of the hook shaped extremity of the lever with the plate, we may
employ any suitable means for such purpose, but as shewn in the drawings herewith,
we employ or interpose a spiral spring g between the lower end or extremity of the
lever a, and the fixed bracket or carrier h, or swivel piece ' which swivel piece /¹
free to turn in its bearings j; which bracket h. may be affixed to the underside of the
mule carriage at any convenient part; the rod i. being free to pass into or through
an aperture provided in the said piece h².
The operation and action of our invention is as follows.
When the end of the lever engages with the fixed piece bracket or stop piece k
which we provide at any convenient part in the race of the mule carriage, that is,
at or near the termination of the run out of the carriage, the said lever is pushed
from its interlocked position or caused to disengage from the piece or plate e., at
which period, as is well known, the winding faller is operated by means of the
ordinary mechanism, so as to fall or to depres the yarn, thus to perform its office or
proper function, consequently by such action, the lever a. is caused to pass in an upward
direction as shewn by dotted lines see Figure 1. At the completion of the winding
or run-in of the carriage, the faller wire being operated or actuated as is well known,
in the reverse direction, that is,-to rise-the lever a. (which may be so depended
from the stud b so that the lower part may incline towards the side e¹ of the slot e²
which may be effected more or less by the employment of a bracket c. having a
greater or less distance between the centres of the faller shaft d. and the stud b.)
then consequently drops and passes to its normal position or interlocks with the
plate e. at e as shewn in Figure 1, by the aid of its own weight, or may be passed
to such position by extraneous means, that is, by the aid or action of the spring as
bereinbefore described, or may be effected by any other equivalent means.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. In combination, the bracket c. lever a. spiral spring g. rod i, swivel bracket h.
substantially as and for the purposes hereiu fully set forth and described in the
drawings hereunto annexed.
2. In combination, lever u. slotted plate e. as and for the purposes herein fully
set forth.
3. The lever a. having at its extremity a projecting part adapted and arranged
so as to be capable of alternately disengaging from and of engaging with a lock
piece or plate, whereby the faller wire may be alternately free to actuate or operate
upon or to be maintained in a rigid or immoveable position with relation to the
yarn at the proper periods, accordingly as the lever is released from or put into
engagement with the lock plate, which lever or arm may or may not be actuated
by a spring, weight or other equivalent means as herein fully set forth.
