We JOHN JACKSON of 62 High Street Lees near Oldham spinner and WILLIAM
HAZLEHURST of 22 Saint Thomas Street (north) Oldham pattern maker both in the
County of Lancaster do hereby declare the nature of our invention for "an invention
as stated in the above title 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 certain parts of spinning mules, consisting of a peculiar
form of cop rail, by the aid of which, the yarn may be wound upon the spindles in
such a manner, so that the cop when formed shall be firmly built, and free from
any soft parts; thus to obviate any waste when the same is unwound.
Another part of our invention consists of an apparatus for controlling the
velocity of the shaft operating the spindles particularly during the operation of
winding, which obviates injury or the breaking of the threads; this we term the
winding apparatus, and is adapted to work in connection with the cop rail above
referred to.

The apparatus is so applied as to be under the immediate influence of the threads
or stretches of yarn in the machine, its object, being to control or govern the speed
of the spindles when winding too fast, which tends to cause an excessive strain on
the yarn, thus to result in a severance of the threads; by our arrangement this is
obviated, the spindles are caused to rotate suitably to accommodate the tension of
the yarn under variable conditions thus we govern the winding spindles by the
yarn and are enabled to dispense with the quadrant and its attendant mechanism
as now used.
In order that our invention may be understood we refer to the accompanying
sheet of drawings.

page_text: parts A A¹ of the rail, which are connected together by two suitable plates B BI
Bee Fig. 2, we provide two pieces C C¹ of peculiar form, which are secured at their
extremities by pins or studs D DI, between the plates B BI, so that the said pieces
may be free to turn thereon, one extremity of the piece D, that is the part opposite
to its fixed extremity, engages with one extremity of the piece D¹, that is the part
opposite to its fixed extremity, in such a manner that the piece D. shall rest
upon or be supported thereby, thus forming at the space between the inner
extremities A and AIII of the outer ends A A' of the rail, a continuous surface for
the passage of a lever or "boot-leg " to be hereinafter referred to.
The piece D is provided on the underside with a suitable screw E, for the
purpose of adjusting the same as may be necessary; the lower part of the adjusting
screw E rests on a suitably curved surface of a sliding piece F, for a purpose to be
hereinafter referred to.
The outer ends A A¹ of the cop-rail, rests, as is well known upon inclined sliding
plates G GI, the plates being connected together by a rod G, a sliding motion is
imparted to the plates by the agency of the screw-rod H; which is caused to rotate
by the engagement of a suitable projection in connection with the catch or lever I,
with any convenient part of the inule carriage'; the rail is situated below the mule
carriage, in the direction of its traverse as heretofore, the toothed wheel or shaper
mechanism being furthest from the delivery rollers or forming the outer end of the
rail as is well known, as the carriage traverses the strips the lever I. is correspond-
ingly actuated and caused to engage with the toothed wheel II so as to operate the
screw-rod. When the formation of the cop is commenced the "boot-leg" commences
its traverse at the part X, and travels to the point ✗I as each stretch of yarn is
wound upon the spindles, afterwards recedes back to its former position, during
which period winding operations cease, as is well known this reciprocating motion
continues until the cop is wound.
When the plates G GI are caused to slide the rail, as is well known is
.consequently caused to lower, at the same time the sliding piece F. is caused to
move on the slide R" in the same direction as the plates G G¹, by the engagement
of a projecting pin J. on the rod GTI with one of the studs K. K on the underside
thereof, as the sliding piece F moves, the pieces C CI are caused to alter their
positions or turn upon their pins D DI suitably to the curvature of the sliding
piece F, at a convenient period, the surface F' of the sliding piece passes under the
lower extremity of the pin L, elevating the same above the surface of the rail in
the part A, such motion occurs at a time when the bowl on lever R¹, or better
known as the "boot leg" (its action being well understood) traverses over that part
of the surface of the outer end or part A. of the rail, this being the time when the
lower point of the cop is being formed, the pin L'being applied at a convenient
part as shewn in the drawings, for that purpose, consequently as the "boot leg
being connected to the "faller wire," M. as is well known, traverses the surface of
the pieces CCI and the projecting portion of the pin L. respectively, obviously the
position of the "faller wire" is correspondingly altered or varied; consequently acting
upon the threads in a similar manner, being such as we desire for the purposes of
producing a firmly built cop.
"
The motion or movements of the pieces C. CI and sliding piece F. are adapted to
take place at a time when the tube or inner portion of the cop is being formed, the
said pieces are so formed or shaped, and employed as the parts as indicated in the
drawings, exclusively for the purpose of enabling the yarn to be wound upon
the spindles cross wise, so as to ensure the inner portion of the cop being firmly
wound upon the spindles, this, being the sole object or principal feature of our
improved rail.
On the shaft R known as the winding shaft, we provide a disc L³, in connection
with which we employ a semi-circular piece M³, one extremity M" thereof being
suitably fixed in a stationary manner, its other extremity being connected to the
counter-faller shaft N. by suitable connecting levers. O. O and O", when the
velocity of the spindles is too great during the operation of winding the yarn, as

page_text: may be the case, the tension of the threads is also great, such event results in the
depression of the faller wire N', thus causing by the agency of the connecting
levers O. O and O", the semi circular piece M to come in contact with the surface
of the disc L, consequently by the aid of friction on the surface of the disc the
winding shaft R. is retarded, obviously the velocity of the shaft P. is retarded which
operates the spindles, by the aid of wheels RI and RI; any resistance having
a tendency to impede the velocity or speed of the shaft P.-which shaft receives its
motion from the main driving shaft of the machine,-likewise effects the velocity
of the spindles, the shaft R receives its motion from the shaft P by the aid of
wheels R and Rш consequently when pressure is applied on the disc L' any slip
there may be, occurs at the main driving shaft of the machine which as before
stated operates the spindle driving shaft P.
We claim to effect by our arrangement, a more reliable method of preventing
damage to the threads of yarn than heretofore, by the use of the quadrant
arrangement, as, when the spindles are winding too fast, which may arise from
various causes, our apparatus automatically applies a resisting force in a simple and
effective manner, at the same time being sensitive in its action.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is
1. The combination of the parts or pieces C. CI the sliding piece F. with the
studs K. K the plates B BI, the loose pin L, the outer ends or parts A A¹ the
stud J. on the rod GT substantially as and for the purposes herein fully set forth
and described in the annexed drawings.
2. The combination of the levers O. O¹ and O the semi-circular piece M³ the
disc L'.wheels R and RI substantially as and for the purposes herein fully set
forth and described in the annexed drawings.
