Improvements in Apparatus for the Winding of Yarns or
Threads.
I, WILLIAM GEORGE GASS, Engineer of Atlas Foundry, Nelson Street, Great
Lever near Bolton in the County of Lancaster, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in or applicable to machines for winding
yarns or thread.
This invention comprises various improvements applicable to winding machinery
similar to or having the same object as those comprised in the Patent granted to
the present applicant and bearing the official number 16305-1888 as well as to
machinery for winding yarns or thread of other types now in use.
""
In machines in which the yarn is wound on to a bobbin, tube, or spindle to
which motion by frictional contact through an "intermediary roller" from a con-
tinuously rotating "driving shaft" or drum-the "intermediary roller" is carried
in a frame or "cradle" pivoted in such a manner that the "intermediary roller
can be lifted from contact with the continuously rotating "driving shaft" and its
motion stopped in order to make the stoppage quicker and more certain--a
fixed brake can be arranged with which the "intermediary roller" comes in contact
when raised from contact with the driving shaft-any number of "cradles" can be
arranged side by side as required.
"
This "cradle" is connected with the "starting handle," by a suitably arranged
"link so that when the "starting handle" is depressed or falls the "cradle" lifts
the "intermediary roller" from contact with the "driving shaft" and so stops it;
when the "starting handle" is raised the "intermediary roller" comes in contact
with the "driving shaft" and rotation commences-the "starting handle" being
retained in its place by a loose catch.
";
in
In order that the spool, bobbin or tube may stop when a thread is broken or
missing I replace the simple catch before mentioned by one of another shape-
which forms part of a light "frame" pivoted in a suitable bearing-on the side of
the pivot opposite to that on which the catch is, the "frame" carries a "box
which are placed any number of "detector or faller wires or similar device-the
"frame" is carried forward beyond this "box "-forming an arm for the purpose
of lifting the remaining threads clear of the thread guide. When a "detector"
wire falls it comes in contact with a suitably placed wiper shaft causing the
"frame" to swing on its pivot and release the starting handle" this falls and by
so doing raises one end of the ", cradle carrying the "intermediary roller"
stopping its motion in exactly the same way as previously described.

The catch portion of the "frame" is so shaped that as the starting handle'
falls it causes an increased movement of the "frame on its pivot, and with the
same motion lifts the "box" and its "detector wires" clear of the wiper shaft
preventing them being damaged and raising the remaining threads clear of the
thread guide. For heavy work a spring could be applied to keep the catch in its
place, but for ordinary work the weights of the different parts are sufficient- -as
the weight of the parts acts to keep them in gear.
In some varieties of winding machines for yarns it is advantageous for the ends
of the centres of the bobbin, tube or spindle to run in parallel grooves so that
the bobbin, tube or spindle may freely rise as it becomes filled-and for this
class of machines the "cradle" carrying the "intermediary roller" is provided
with parallel grooves for this purpose which form part of and partake of the
movements of the "cradle "before described.

page_text: The improved stop motion herein described is equally applicable to any form of
spindle or drum winding machine where threads are delivered to be wound doubled
or twisted the "starting lever" being equally adapted for moving a belt or cord
from a fast pulley on to a loose pulley for the purpose of stopping the spindles or
drums which do the winding the other parts being substantially the same as
previously described.

Improvements in Apparatus for the Winding of Yarns or
Threads.
I, WILLIAM GEORGE GASS of Atlas Foundry, Nelson Street Great Lever near
Bolton in the County of Lancaster Engineer 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:-—
This apparatus relates to improvements in devices for the winding of yarn on to
paper tubes, bobbins, or spindles, and is applicable to machines which wind the
thread on to a tube with a quick traverse; the traverse being a fixed distance-or
to quick traverse winding machines with a variable traverse of the type for which
a Patent was granted to me bearing the official number 16305-1888; or to
spooling frames for the winding of yarn or thread on to a wooden spool with a
slowly moving traverse. The device is for the purpose of rapidly and conveniently
stopping the motion of the bobbin cop or tube without causing any rub or friction
on the yarn which is already wound and for automatically causing such stoppage in
the case of the breaking of the yarn which is being wound.
In referring to the accompanying drawings,
Fig. 1) is a cross section of the device giving a general view of the arrange-
ment.
Fig. 2) is another view, in plan, but with the bobbin or tube removed.
Fig. 3) is a detail of a catch arrangement for the starting lever when the
automatic stop motion is not used.
"
In each view the same letter applies to the same part. In Figs. 1 & 2. A is the
continuously rotating shaft; B the intermediary roller, of which b. b. are the
trunnions ; C is the bobbin, cop, or tube,-hereinafter referred to as the "bobbin "
-in the process of winding, of which c c are the trunnions. These run in
suitably shaped guide slots e. e. which form part of the cradle D. D. The round
fixed bar F. F, forms the bearer or fulcrum on which the cradle D. D. moves.
DD is provided at the end of its arms with two U shaped slots, open at the top,
forming bearings for the trunnions b. b. of the intermediary roller B. D D is also
supplied with two other similar U shaped slots ff-but inverted, so as to rest on
the fixed rod F. F. G is the starting lever of which 9 is the handle-this swings
on a suitably carried pin I, and is connected to the cradle D D. by the link H at i.
and respectively. J is the frame-which is free to move on the piu E suitably
carried and provided at its upper end with the stop motion box L, and wires M.
K is the catch peg fixed to starting lever G which engages with the corresponding
catch W of the frame J. X is a safety catch on frame J to prevent lever G from
dropping too far; T is a brake fixed on to bar F F. R is the thread-guide operated
in any desired way. N-S-R are guides for the thread of the ordinary form. U is
the oscillating knocking off motion in common use.
The action of the device is as follows.
We will suppose yarn or thread is being wound on the bobbin C-the positions
of the various parts will be as shewn by the black lines in Fig. 1.
The shaft A transmits its motion to the intermediary roller B-which in its turn

page_text: causes the bobbin C to rotate and wind on yarn or thread. The starting lever G
is held up by the catch peg K, through the catch W on the frame J-the weight
of J is so arranged that it tends to keep the catch W pressed against the peg K.
The thread after passing over the rod N or its equivalent arrangement-
usually a device to put a tension or drag on the yarn or thread-passes through
the stop motion wires M over the roller S or its equivalent through the guide eye R
to the thread guide P and thence to the bobbin C. The tension or drag of the
thread O is sufficient to keep the stop motion wire M in its top position when it is
clear of the knocking off motion U.
But suppose the thread O breaks-there is then nothing to hold the wire M in
position, and it falls as far as it is allowed by the shape of the wire, which is the
form in common use. The knocker off U comes in contact with the lower part of
the wire M and forces the box L backward. This causes the frame J to swing on
the pin E and throw the catch W out of gear with the peg K-and allows the
lever G to fall.
The lever G is of sufficient weight or is assisted by the spring S¹ to overbalance
the frame D D D, roller B & bobbin C. This weight or its equivalent acting
through the link H raises the roller B. until it comes in contact with the brake T
and the motion of roller B is stopped and also that of bobbin C which then ceases
to wind at the same time the lever G while falling acting by means of the peg K
on the inclined face W of the frame J causes the frame J to swing still further
back and prevents the box L and stop motion wires M from being damaged by the
subsequent motion of the knocker off U-and the different parts assume the
positions shewn by the dotted lines (Fig. 1). When the broken thread is pieced
the attendant pulls the threads tight so as to raise the wires M. to their top position
and then the handle g of lever G is raised the intermediary roller B gradually
comes in contact with the rotating shaft A and begins to revolve easily and with-
out shock and the winding recommences-the catch W again gears with the peg K
and the parts are together in their first position.
It will be readily seen that any number of threads may be wound on to one
bobbin at the same time by having a corresponding number of wires M in the
box L.
The method shewn in the drawing (Fig. 1) of passing the thread or threads
over the rods N. S and through the eye R is not requisite under all circumstances
and will require to be varied to suit different methods of winding & does not affect
the mechanism.
Instead of having the guides e. e. attached to the frame D D D they may be
dispensed with and the bobbin C may be carried as shewn in the Specification of
Patent previously mentioned (viz. No. 16305-1888) in order to suit the mechanism
and purpose therein described. Any desired form of knocking off motion may be
used in place of U. In (Fig. 3) the automatic stop motion is dispensed with, and
a simple weighted catch V is used which is operated by hand as required.
I have herein only mentioned one bobbin C and its attendant mechanism-but
it must be remembered that any number of bobbins and attendant mechanism may
be used by placing them side by side and on each side of the machine as required
In place of the continuously rotating shaft A Fig. 1 a succession of drums or
pulleys may be used but a shaft such as that shewn is most easily made.
Intermediary rollers run in fixed bearings are in common use, and devices similar
in their action to the inclined face W have been used therefore I do not claim
them broadly.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1) In a machine or apparatus for the winding of yarns or threads, the com-
bination of the intermediary roller B, with the cradle D, guides e e, bar F, and
brake Tall substantially as and for the nurnace anecified

page_text: 2) In a machine or apparatus for the winding of yarns or threads, the com-
bination of the roller B, cradle D, brake T, with the lever G, link H, and catch W,
all substantially as and for the purpose specified.
3) In a machine for the winding of yarns and threads, the combination of the
swing stop motion frame J, box L, & catch W, with catch peg K, lever G, link H,
cradle D, bar F, roller B, brake T, all substantially as and for the purpose
specified.
4) A device for the purpose of winding yarns or threads substantially as
described and for the purpose specified.
