PROVISIONAL SPECIFICATION"
left by the said William Weild at the
Office of the Commissioners of Patents, with his Petition, on the 12th
November 1856.
1. WILLIAM WEILD, of the City of Manchester, in the, County of Lancaster,
Machinist, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN MACHINERY FOE DOUBLING, TWISTING, AND WINDING YARNS OR THREADS
ON TO BOBBINS OR SPOOLS," to be as follows:-
Firstly, my Invention relates to doubling, twisting, or winding, machines. It
consists in arrangements for holding the bobbin, on which the yarn or thread is
to be wound against the surface of the drum which is employed to rotate it,
and. for bringing and holding the bobbin out of contact with the drum when
required, namely, in a frame in which the axis of the bobbin is placed in an
horizontal position, the bobbin being free to rotate on its axis. This frame has
an axis (parallel to that of the bobbin) on which it is free to oscillate, which
axis is fixed parallel to the axis of the drum that rotates the bobbin, the frame
being weighted so as to press the bobbin against the surface of the drum:

page_text: The frame has a lever handle jointed on it, one end forming a hook or notch,
which hooks hold of a corresponding book or notch formed on one bearing of
the axis of the frame when the frame is pulled forward by it, thus holding the
bobbin out of contact with the surface of the drum. Pushing back the lever
handle releases it from the notch. and allows the hobbin to come against the
surface of the drum.
Secondly. my Invention relates to doubling. twisting, or winding machines.
It consists in certain arrangements for adjusting the length of movement of
the traverse bar to which the guides are fixed, for spreading the yarn or thread
evenly on the bobbins or spools, described as follows:-The cam from which
the movement is obtained acts upon a lever placed at a right angle to thu
traverse bar, which has a slot in it in that direction, in which a suitable stud
is placed that takes into a die fitted in a slot formed in the end of the lever:
the adjustment of this stud in the slots regulates the length of the traverse
movement
Thirdly, my Invention relates to machines for doubling, twisting, and winding
yarns on to bobbins or spools, principally to prepare such yarns as are intended
for the pile of pile fabrics. Two or more bobbins are placed on pegs or
spindles fixed in a table, having a vertical axis that is placed in suitable
bearings. This table is rotated on its axis, so as to give the required twist to
the yarns or threads. The yarns or threads from the bobbins placed on the
the table are wound on to one bobbin, at the same time that the twist is being
given by the rotation of the table. In place of this arrangement of machinery.
the required twist may be put in the yarn or threads by first doubling and
winding the number of threads required on to one bobbin or spool, and then
winding the doubled threads off the end of this bobbin or spool on to another
bobbin.
Fourthly, my Invention relates to machines for winding yarns or threads on
to spools in the conical form. The spool is placed on a spindle that has a tooth
pinion upon it, which geers with a toothed wheel from which the spool receives
rotating motion. The spindle of the spool has its bearings in a frame that has
an axis upon which it can oscillate; this oscillation of the frame is to bring the
toothed pinion in and out of geer with the toothed wheel that drives it. When
the frame is in that position in which the pinion and wheel are in geer it is
latched. and it is weighted so as to bring the pinion and driving wheel out of
geer, when the latch is liberated. A V-formed piece is arranged to slide on a
bar attached to the oscillating frame: it takes on each side of the spool, and the
material as the spool fills slides it along to one side of the frame, so that when
the spool is full, the V piece comes against an incline on the latch, and releases

page_text: the frame, which brings the wheels out of geer. The guide which spreads on
the thread is fixed on the traverse bar, so as to slide, but is held by friction
sufficiently fast as not to move by resistance of the thread. Its position on the
traverse bar is changed as the bobbin or spool fills, by coming at the end of
each reciprocation against the V piece. which slides it on the traverse bar.

FOR DOUBLING. TWISTING, AND WINDING YARNS OR THREADS ON TO BOBBINS OR
SPOOLS," upon the condition (amongst others) that I. the said William Weild,
by an instrument in writing under my hand and seal. should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that 1, the said William Weild. do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
Firstly, my Invention relates to doubling, twisting, or winding machines. It
consists in arrangements for holding the bobbin on which the yarn or thread is
to be wound against the surface of the drum which is employed to rotate it,

page_text: and for bringing and holding the bobbin out of contact with the drum when
required. These arrangements consist in a frame in which the axis of the
bobbin is placed in an horizontal position, the bobbin being free to rotate on its
axis. This frame has an axis (parallel to that of the bobbin) on which it is
free to oscillate, which axis is fixed parallel to the axis of the drum that rotates
the bobbin, the frame being weighted, so as to press the bobbin against the
surface of the drum. The frame has a lever handle jointed to it, one end form-
ing a hook or notch, which hooks hold of a corresponding hook or notch formed
on one bearing of the axis of the frame, when the frame is pulled forward by
it, thus holding the bobbin out of contact with the surface of the drum
Pushing back the lever handle releases it from the notch, and allows the bobbin
to come against. the surface of the drum.
Sheet 1 of the 3 Sheets of Drawings annexed hereto, exhibits a sectional
elevation (Fig. 1). and a side elevation (Fig. 2). of a machine which may be
considered a winding. doubling, or twisting machine, having improvements
applied, described as the first part of my Invention. Figs. 3 and 4 are detached
views, on an enlarged scale. of arrangements for holding the hobbin against
the surface of the drum which rotates it. Fig. 3 is n side view, and Fig. 4. a
front view. a. front beam, on which the stands (b) are fixed, for carrying the
bearings of the axis (c) of the frame c. This frame has arms c³ from it, upon
which a weight c is suspended. The axis of the hobbin d (formed by a spindle
passing through it) is carried by the frame c. the bobbin being pressed by the
weight against the surface of the drum e placed on a shaft e'. On the side
of the lever frame c the lever handle e' is jointed at. c (as shewn); the hook or
notch upon it hooks upon the hook or notch formed on the stand (b) when the
lever handle is pulled sufficiently back.
Secondly, any Invention relates to doubling, twisting, or winding machines.
It consists in certain arrangements for adjusting the length of movement of
the traverse bar to which the guides are fixed for spreading the yarn or thread
evenly on the bobbins or spools. In this arrangement, the cam from which
the movement is obtained acts upon a lever placed at a right angle to the
traverse bar, which has a slot in it in that direction. in which a suitable stud
is placed that takes into a dic fitted in a slot formed in the end of the lever:
the adjustment of this stud in the slot regulates the length of the traverse
movement. This part of my Invention is shewn applied to the machine
exhibited by two views (Fig. 1 and 2) in Sheet I, and the machine exhibited
by three views in (Fig. 8. 9. and 10) Sheet. 2. Detached views of details
or shewn on an enlarged scale on Sheet 1. Fig. 5a front, Fig. 6 un edge
sectional, and Fig. 7 a plan sectional view. The cam for actuating the traverse

page_text: bar is marked f; it acts upon a bowl fixed in the lever g, which has its
fulcrum g¹ on a bracket attached to the framing of the machine. The upper
end of the lever has a slot g, in which a die g" is fitted, so as to be free to
slide up and down. A piece h is fixed on the end of the traverse bar i, which
has an undercut slot as shewn. The head of a stud or bolt h' is fitted so as
to be moveable up and down this slot; it passes through a tube having a
shoulder upon it, and this tube passes through a hole in the die g³. The tube
projects slightly beyond the die, so that the nut on the end of the stud or
bolt h, when screwed tight, will not bind against the die. The stud his
fixed in the part h when the nut is screwed tight; it forces the shoulder of the
tube against the face, and draws the head of the bolt against the back of the
undercut slot in the part h. It will be seen that the machine shewn by Fig. 1
and 2 is double-sided, having six drums on one shaft. each drum driving two
bobbins, one on each side of it. The drum shaft e' is the first motion shafi.
and on the end of it the fast and loose driving pulleys e are placed. The
shaft h, on which the cams for the traverse motion are placed, is driven by a
train of wheels from the end of the shaft e'. The traverse bar slides in guides
formed in brackets be secured to the beams a, which are carried by the end
frames A. The thread is distributed, by a grooved pulley free on a stud secured
in an arm adjustable on the traverse bar i.
Thirdly. my Invention relates to a mode of twisting threads or yarns together
and winding them on to bobbins or spools, and is intended principally for the
preparation of such yarns or threads as are intended to form the pile of pile
fabrics. This method consists in winding the number of threads required on
to one bobbin or spool, and then winding the threads off the end of this bobbin
or spool on to another bobbin. It will be understood that in winding the
threads off the end of the bobbin or spool, there will be one turn of twist for
each turn of the threads round the spool or bobbin from which they are wound,
so that by regulating the diameter of the bobbin or spool, and taking care not
to increase the diameter materially by the threads wound upon it, the required
amount of twist may be obtained as near as is practically necessary for the
purpose. When the threads are wound upon the bobbin in the cylindrical
form they are drawn off the end of the bobbin to put in the twist. by means
of a flyer free to rotate on the end of a peg or spindle on which the bobbin is
placed. The most uniform amount of twist may be given when the threads
to be twisted together are to be drawn from the end of a bobbin or spool
wound in the conical form with a coarse traverse. In a bobbin or spool wound
in the conical form, the length of thread distributed by each backward and
forward movement of the traverse bar is the same, and these lengths have each

page_text: the same number of coils or turns round the bobbin or spool, consequently
there will be an uniform quantity of twist given to the threads when wound
from the end of the bobbin or spool. Though there is a uniform number of
turns in each length of thread distributed by one backward and forward move-
ment of the traverse bar, yet that portion of the length wound round the small
end of the cone has a greater proportion of turns or coils than that wound on
the large end of the cone, as is well understood, but the twist due to theso
coils or turns when the yarn or threads are wound from the end of the bobbin
becomes equally and uniformly distributed at the time of winding, and during
the subsequent process of weaving. A flyer is not required in drawing off
the threads from a bobbin or spool wound in the conical form. The position
of the bobbins in the machine when twist is imparted to the threads upon them
is shewn in Figs. 2. 9. & 10 of the Drawings: being a cylindrical, and ' a
conical bobbin or spool.
Fourthly, my Invention relates to machines for winding yarns or threads
on to spools or bobbins in the conical form. It consists in arrangements
described as follows:-The spool is placed on a spindle that has a toothed
pinion upon it, which geers with a toothed wheel, from which the spool or
bobbin receives rotating motion. The spindle of the spool has its bearings in
a frame that has an axis upon which it can oscillate; this oscillation of the
frame is to bring the toothed pinion in and out of geer with the toothed wheel
that drives it. When the frame is in that position in which the pinion and
wheel is in geer, it is latched, the frame being weighted so as to bring the
pinion and driving wheel out of geer when the latch is liberated. A V-formed
piece is arranged to slide on a bar attached to the oscillating frame; it takes
on each side of the spool, and the material, as the spool fills, slides it along the
bar, so that when the spool is full. the V piece comes against the latch, and
thus releases the frame which carries the axis of the bobbin, and brings the
pinion out of geer with the wheel. The guide which spreads or distributes the
thread is arranged on the traverse bar. so as to slide, but is held by friction
sufficiently fast as not to move by the resistance of the thread. Its position
on the traverse bar is changed as the bobbin or spool fills by coming at the
end of each reciprocation against the V piece, which causes it to slide on the
traverse bar. A double machine for winding six bobbins or spools un each
side. constructed according to this part of my Invention, is shewn by Figs. 8.
9. and 10, Sheet 2.
Fig. 8 is a front or side elevation. Fig. 9 a sectional end elevation, and
Fig. 10 an end elevation: Figs. 11 and 12 are detached views on an enlarged
scale, Fig. 11 being a plan view and Fig. 12 a sectional elevation. The two

page_text: detached views shew the mechanisın required for one bobbin or spool, a
duplicate of this mechanism being required for each bobbin or spool; conse-
quently the following description will only refer to the mechanism for one
bobbin or spool. «. front beam, on which the brackets for carrying the
operating parts are fixed; e¹, shaft (having its bearings in the brackets b');
e, wheel, gearing with pinion e fixed on the spindle, forming the axis of the
bobbin or spool d. This spindle has its bearings in a frame c. which has its
axes carried by the brackets b, upon which axes the frame can oscillate. That
part of the frame c" is added as a weight sufficient to overbalance the weight of
the spool when full, and other parts upon the frame, so as to lift the pinion e³
out of geer with the wheel e when liberated, under which circumstances the
weighted part c" will rest upon the top of the beam a. The weighted tail part
is kept up, and thus the pinion in geer with the wheel by a weighted latch c'
(having its fulcrum at c), which comes under a projection from the frame
when the front part of the frame is forced down. 'The wheels are brought
out of gear by pushing the latch c on one side, which allows the weighted
tail part to act as before described. c is a V or conical presser, which is
fitted to slide on the cross bar c' of the oscillating frame. It is made to the
form of the cone of the spool intended to be filled with yarn or thread, and
as the spool fills it is slided along the bar till a projection from it (or an
adjusting screw fitted in the projection) comes against the latch c. which
thus liberates the frame when the bobbin or spool is full.
The traverse bar i has a movement equal to the length of the cone of the
intended spool or bobbin, and it may have a uniform traverse in both direc-
tions, or a slow traverse in one direction, and a quick one in the other direc-
tion. The traverse bar i in this case is a cylindrical rod with one side
removed, to present a flat surface. The guide for the thread, is fitted on
the traverse bar, so as to slide, but not by the resistance of the thread, which
passes over the rod, and between the two pins forming the guide, and then
on to the bobbin or spool, as shewn. The friction to hold the guide to the
traverse bar sufficiently tight is obtained from a bow spring, as shewn, the
action of which can be regulated within certain limits by an adjusting screw
placed in the front of the guide. The guide is slided along the traverse bar as
the bobbin or spool fills, each time a projection on the guide comes against one
on the V or conical part ce, which occurs at the end of each complete recipro-
cation. When the full bobbin or spool is to be replaced by an empty one, that
end of the spindle opposite to that end on which the toothed pinion is fixed
is lifted out of the slotted bearing in the frame; this allows the other end of
the spindle to be withdrawn from the hole forming, its bearing. The full

page_text: bobbin is then removed from the spindle and replaced by an empty one, the
notches on the bottom of the bobbin being entered by projections
on the pinion, by which means the bobbin is carried round with
the spindle. When the spindle is placed in the frame, and the yarn or thread is
attached, the V piece is slided against the cone, and at the same time the
guide is slided on the traverse bar, till the projections on the guide and V
piece come in contact; then the front part of the frame may be forced down,
and the filling of the bobbin or spool will commence. The pressure of the
cone or V piece upon the material wound on the bobbin or spool may be regu-
lated by friction by applying a spring to it, which may he made to press upon
the bar c. This spring may be made to act on the under side of the bar c',
or it may be arranged in the same manner as that in the guide i'. The pressure
of the cone upon the material wound on the bobbin or spool may also be
obtained from a weight or weighted lever. Arrangements for this purpose
are shewn on Sheet 3 by the Figures 13, 14, and 15, respectively a front, side
sectional, and plan view. Two arrangements are shewn applied, but either of
them will answer singly. c is a cord attached to a projection from the under
side of the cone part c; it passes over a pulley fixed on an axis in the side
bracket. (b) and then descends, having a weight c" suspended at its end. c³ is
a two-armed weighted lever, having its fulcrum on a stud fixed in the beam a
at c²; the end of one arm fits into a slot formed in a part projecting from the
underside of the cone part c. Figs. 13, 14, and 15 shew a modification of
this part of my Invention, wherein the spindle on which the spool or bobbin is
placed is driven or rotated by resting on two surface wheels, after the manner
commonly used in silk winding machinery. A pulley corresponding to the
pinion is fixed on one end of the spindle, and another is screwed on the
other end of the spindle when the spool or bobbin is placed on it; these pulleys,
when the frame is held up by the latch, cach rest on the surface pulleys or
wheels c on the shaft c': This method of driving will only answer for filling
conical bobbins or spools with fine yarns or threads requiring little driving
power. In the machine shewn by Figs. 8, 9, and 10, e are the driving pulleys
on e, the first motion shaft. The shafts e' are driven from e by a series
of spur wheels. The arrangement of the cam shaft and traverse motion and
gearing is the same as that described in reference to the first and second parts
of my Invention.
I have now particularly described the nature of my Improvements, and the
methods of carrying them into effect, and claim as my Invention,-
Firstly, as relates to doubling. twisting, and winding machines, the arrange-
iments for holding and pressing a bobbin on which the yarn or thred is being

page_text: wound against the surface, giving motion to it, and withholding it from the
surface when required, substantially as herein-before described under the head
of the first part of my Invention.
Secondly, I claim the arrangements for adjusting the length of the move-
ment of the traverse bar in machines for doubling, twisting, or winding. sub-
stantially as herein-before described under the head of the second
part of my Invention.
Thirdly, I claim the system or method of twisting together two or more
threads or yarns intended for the pile warp of pile fabrics, as herein-before
described under the head of the third part of my Invention.
Fourthly, I claim the general arrangement of the machine for winding yarns
or threads on to spools or bobbins in the conical form, as described under the
head of the fourth part of my Invention.
Fifthly, I claim, in winding bobbins or spools in the conical form, the driving
of the spool or bobbin directly by toothed geer; the arrangements for engaging
and disengaging the bobbin from the driving wheel or wheels, whether toothed
or surface wheels; the arrangements for distributing the yarn or thread upon
the bobbin or spool, or for adjusting the traverse guide as the hobbin or spool
fills; the arrangements by which the bobbin or spool is stopped when full;
the means of adjusting the pressure of the cone upon the material as it is
wound on the bobbin; all substantially as described under the head of the
fourth part of my. Invention.
In witness whereof, I, the said William Weild, have hereunto set my hand
and seal, this First day of May, in the year of our Lord One thousand
eight hundred and fifty-seven.
