Massachusetts, United States of America.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
One object of this invention is to facilitate the winding of that class of cops in
which the threads are laid symmetrically side by side and crossing each other and
to produce apparatus for effecting this result in which apparatus a guide recipro-
cating opposite a rotating spindle is combined with means for securing an increment
or decrease of motion whereby the spindle occupies a different position opposite the
guide at the termination of each reciprocation of the guide; cops and apparatus of
this character are described in the Specification of prior Letters Patent No. 6497
of 1892 granted to A. J. Boult. This object of my invention is attained by
supporting the guide upon a swinging frame so that there is less weight to the
reciprocating part and less tendency to "throw" from the weight of the said part.
The invention further embraces means for varying the extent of the increment or
decreased motion embodying a pulley capable of being increased or decreased in
diameter and constituting part of the gear between the spindle and the
reciprocating guide.
The invention further comprises means for overcoming the objections incident to
the use of cop tubes of irregular character by permitting the guide to be moved
away from the cop by any irregularity of the latter but preventing it from moving
inward again.
Another object of this invention is to automatically supply predetermined
numbers of cops reels or the like to boxes or other receptacles, and also if required
to press said cops to condense and mould the same.
The cops reels or the like after being wound are dropped into the receptacles of
a preferably endless conveyor which moves with an intermittent motion and carries
the cops successively between the dies or faces of a compressor which acts while
the conveyor is at rest.
Each cop is thus compressed and moulded and formed into shape for the shuttle
of a sewing machine or for other machine or purpose as required.
The conveyor carries the cops successively to a shoot which conducts each cop
to a position opposite one of a series of parallel spindles carried by an endless band
or chain.
After a cop is brought opposite a spindle a pusher pushes the cop onto the
spindle and successive cops are thus delivered upon the spindle until a determined
number is placed thereon-this number can be determined by an adjustable stop-
when the movement of the series of cops on the spindle as the last cop of the
series is placed thereon releases a pawl which acts on the chain and carries it one
step until another spindle is opposite the pusher and is filled with cops in like
manner

page_text: The filled spindles are carried above a box or other suitable receptacle and
when a determined number of spindles are above the box with sufficient number
of cops to fill the box, the latter is raised, and a blade or other device pushes
the cops off the spindles, or the latter are drawn back and the cops fall into
the box.
A bell or other device serves to indicate when the spindles are full enough to
supply the box.
The cops are thus automatically pressed, and supplied to the boxes.
cases the pressing device may not be required and it may be omitted.
In some
The invention further consists of a new and improved cop or package of yaru or
similar material wherein the different coils are crossed and bound together so as to
maintain the shape of the package but without the use of any bobbin or other
support and in the method and means of making such cops or packages, the
means being such as are hereinbefore referred to, and the method being to wind a
series of parallel coils, each coil being carried back at each end of the cop, and to
remove the cop from the spindle, pulling its ends apart, introducing previously,
if desired a knotted loop into the centre of the cop, by which it may be
suspended.
Various mechanical devices may be employed for giving the proper movements
to the parts.

Improvements in or relating to the Winding of Yarn, Thread, and
the like, and the Pressing and Boxing of Cops, Rolls, and Balls
thereof.
A communication from FREDERICK HERBERT BISHOP, of 226 Devonshire
Street, Boston, Suffolk County, Massachusetts, United States of America,
Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 invention relates to the inethod and means of winding threads, yarn,
cordage, etc. either single or doubled to any desired extent to form cops rolls or
balls of a peculiar character and to means for pressing the said cops rolls or balls
(hereinafter termed "cops," generically) and packing the same in boxes or other
receptacles as fully set forth hereinafter and as illustrated in the accompanying
drawings in which
Figure 1 is a diagrammatic view illustrating the manner in which a thread is
laid upon a tube or holder in starting the winding of the novel cop by the improved
method.
Fig. 2 is an enlarged diagrammatic view illustrating the laying of the successive
windings of thread in building up a cop with an "open" wind.
Fig. 3 is a view illustrating part of the surface of a cop when wound with an
open wind.

receiving a supporting loop.

Fig. 6 is an elevation in part longitudinal section, showing one form of mechanism
for winding the improved cop;

page_text: Fig. 8 an elevation showing the devices at the opposite end of the machine;
Fig. 9 an elevation illustrating certain modifications, together with an improved
device for correcting the effects of irregular cop tubes;
Fig. 10 is a view illustrating the method and means of winding threads doubled.
Figs. 11 to 17 are views illustrating the construction of mechanism for pressing
the cops and packing them in boxes.
For many purposes it is desirable to form a cop in which the entire body of
thread shall be closely compacted and at the same time prevent the fraying or
separation of long strands of thread, should the threads be worn or broken at any
portion of the surface and to this end the peculiar winding hereinafter described
has been devised. As hereinafter described, the cop is wound on a rotating holder
and the thread laid by a reciprocating guide.
Referring to Figure 1 it will be seen that the first coil 1, starting at the point y
is laid (with any desired number of turns) upon the surface of the holder or cop
until it reaches the opposite end, and is there bent back forming a bend or
knuckle y'. The thread is then carried as a reverse coil 1º, to the opposite end, but
the relative movements of the holder and guide are varied, that is, the holder.
moves to so much greater an extent than is necessary to bring the point y opposite
the guide, as the latter returns to its first position, that the bend y² of the reverse
coil 1 instead of being directly upou the bend y is at a distance therefrom at y².
This distance may be any distance required, that is the threads of the different
coils may lie close together or may be separated to the extent of a half-inch or
more. From the point y² a second coil 2 is laid parallel to the coil 1, until the .
opposite end of the cop is reached when the thread is bent back, forming another
bend or knuckle y³ after which the thread is laid as a reverse coil parallel to but
distant from the coil 1ª.
It will be seen that as each coil reaches the end of the cop, it is bent back
forming a bend, and that when the coils are laid open, as shown, these bends,
instead of being one upon the other, are at a determinate, definite and regular
distance from each other, and that as the coils are laid, the bends will finally be
carried around the periphery until there is at each end a series of bends extending
completely around the periphery at a uniform distance apart.
After the bends have thus far been laid completely around the periphery, a
second series of coils will be laid upon the holder or cop, but when the coils are
laid open, as shown, the threads of these coils will be laid in the first instance
between the coils 12; the first coil of the next series (as for instance, the
thread 2ª Fig. 2) being laid in proximity to the thread of the coil 1, and carried
across the latter, and bent back, as shown in said figure, and the next coil as 2,
will
be laid adjacent to the coil 2, and the next coil 2 adjacent to the coil 3, and so on,
the coils 3° 3° 3° etc. following the coils 2° 2° 2, and thereafter other coils will be
laid, until the entire space between the first laid coils 1, 2, 3 etc. is filled up, after
which the thread will be laid in a second layer in coils upon the first layer of
threads thus formed, the successive layers all being formed like the first and the
surface of the cop in each layer presenting the appearance indicated in Fig. 3.
It will be seen that by this means the successive coils of thread are laid upon
each other so as to cross and tie down each other upon the lines 22 Fig. 3,
throughout the entire surface of the cop, and that if one of the threads should be
cut or broken at any point, the loose thread will not generally be more than a
fraction of an inch in length, so that the entire mass of thread upon the cop is
practically tied down throughout the entire extent of surface of the cop.
It will be seen that when the cop is built up in the manner described, the
distance between the successive coils depends upon the increment (or decrease) of
rotation of the holder in respect to the reciprocation of the guide, whereby as the
guide reaches the end of each movement, it is brought to a point at a greater
distance from that which it reaches at the termination of its prior movement, and
it will be seen that there must be such an increase of movement that after one
series of coils has been laid completely around the holder, the next series must be

page_text: It is not
laid not directly upon the first but a point beyond the coils of the first.
absolutely necessary that this point should be such that the second series of coils
are in contact with the first, as the same might be laid midway between those of
the first, and the next series midway between the other series, and so on until the
surface of the holder is covered with the first layer, after which the successive
layers of the cop are built up as before.
It will be seen that a cop formed as above described cannot unravel even if the
surface threads are cut or worn at different points, that the integrity of the cop is
thus preserved, and that the surface of the cop at all times presents an extremely
ornamental appearance.
It is customary in putting up worsted and zephyrs for the market, to wind the
yarn upon a reel, and after the proper amount has thus been wound to cut the yarn,
take the material from the reel and twist it, or else fold it together, forming a flat
hank or skein, tying a piece of thread or yarn around the material of each hank to
hold the same together at a single point.
This mode of putting up this material for the market requires that after a skein
or Gumber of skeins have been purchased, the yarn shall be wound off into a ball
or "matted," involving an expenditure of time and labour upon the part of the
purchaser, while the skeins are apt to get tangled and broken in packing, to prevent
which it is necessary to wrap them in separate bundles.
In order to overcome these objections in packing yarns or other threads or
material, the yarn is first wound onto a spindle or collapsible holder, or the same
may be wound upon a very thin tube of paper, supported upon the spindle or upon
a spindle made in sections, so that in either case after the cop is formed, it can be
removed from the spindle, and when the paper tube is employed, the latter can then
be withdrawn.
The cop is then seized at the opposite ends, and these ends are gradually drawn
apart, so as to elongate the mass of threads, separating to a degree the coils, so
that those at the centre are elongated and practically brought together as the mass
is elongated and reduced in diameter, such reduction being from one-half to one-
fourth the diameter of the cop, with a corresponding elongation.
yarn
This reduction in diameter and elongation of the mass tends to loosen the
to a certain extent and prevent it from becoming stretched, while as there is no
core or supporting holder, the mass is so flexible that there can be no cutting of
the yarn, it being well known that for knitting purposes the yarn must be preserved
absolutely free from any stretching, cutting or abrasive action. The stick or mass
of yarn thus formed has peculiar advantages over the ordinary skeins or hanks, as
it is impossible for two masses to become tangled together, the thread in each mass
crosses at so many points, that there can possibly be no tangling of the yarn in
that mass, while the necessity of subsequent handling and winding by the
purchaser is absolutely prevented. It will further be seen that however much the
stick of yarn may be reduced the number of such sticks may be packed together
without any possibility of entanglement.
A peculiar advantage of the article thus produced is the facility of delivering the
yarn, as the stick may be hung from one end and the yarn drawn from the end
without resistance or stretching, twisting or entanglement.
One means of providing the stick with a suitable support is to double a cord so
as to form a loop y, Fig. 4, knotted at the ends so as to form enlargements b,
introduce the knotted end into the central opening of the cop and then elongate
the latter, causing it to shrink upon the cord and hold it in place, when the loop y
at the end will afford means of hanging the cop to any suitable support as
in Figure 5.
The knobs or enlargements seen at the ends of the cop in Figure 5 are produced
by the ends or bends of the coils which assume that form when the cop is
extended.
One form of mechanism by means of which the improved cops may be built will
now be described.

page_text: The frame A, Figures 6 to 9, is suitably constructed to support the operating
parts including a spindle a, and means for rotating it, a thread guide C, having an
eye x, and means for reciprocating the said guide, and appliances for varying the
relative action of the guide and spindle so that at the end of each reciprocation
the guide will occupy a different position as regards the holder or cop, that
is it will be opposite a point on the periphery of the cop back of or in advance of
the point to which the guide was opposite at the previous reciprocation.
As shown, the spindle a is the end of the driving shaft 9, but any other suitable
form of support for a holder (solid or tubular) may be used. As shown, the
spindle projects from the side frame to receive a tubular holder 10.
The shalt 9 for rotating the holder is driven by a driving pulley 12, receiving a
driving belt, turning loosely on the shaft 9, and having an inner bevelled face to
engage the outer bevelled face of a clutch pulley 13, turning with but sliding on
the shaft 9, the pulley 13 being pressed into engagement by a spring 15 and
carried out of engagement by the downward pressure of a bevelled projection 20
upon an arm 19 extending from a rock-shaft 21, when the said projection 20 is
brought against the bevelled face of a collar 22 on the pulley. A spring 18 tends
to turn the shaft to throw downward the arm 19 and carry the pulleys out of
engagement. A suitable detent is employed for maintaining the shaft 21 in position
to keep the projection 20 out of contact with the collar 22. Thus the shaft 21
carries at one end an arm 45 (Figures 6 and 7) with a cross shoulder 46 that
engages a cross shoulder 43 upon the arm 42 of a lever E, thereby preventing the
rocking of the shaft 21, under the action of the spring 18, so long as the shoulders 43,
46 are engaged when the pulley 12 will drive the shaft.
A handle E upon or
secured to the shaft 21 serves as a means of turning it by hand.
C
As the guide in this class of machines must be reciprocated very rapidly, it has
been found that unless the guide is very light in weight, the momentum from the
rapid movement will tend to carry it out of position and interfere with that nice
and regular operation which is necessary in order that the thread as it is brought
to each end of the cop may be laid across one of the preceding threads with a
sharp bend and carried back at one side of said preceding thread. Therefore the
guide C moves on a carrier frame F, the guide being of very thin light metal and
sliding upon the frame which is of heavier material and which is pivotted or
otherwise supported so that it can be carried outward as the cop increases in size;
it being necessary to the formation of a cop of the character desired to maintain
that portion of the guide which has the guiding eye in close contact with the cop
throughout the entire series of operations of building up the cop. Thus, the guide,
in which is the guide opening consists of a thin blade of metal with an opening
receiving a porcelain or other vitreous stud i, in which is a notch .c, while the
frame F, Figures 6 and 7, consists of an arm 4, with a hub 4*, swinging on a
stud 26 at one side of the main frame, a horizontal rib 34, having two parallel slots
receiving the arms of a guiding bracket 35, secured to the guide C. From the
lower arm of the bracket 35, a stud 40 extends into the groove w of a cam
wheel D, secured to a shaft 25, extending through the hollow bearing or sleeve 27*
of the frame, and driven by devices hereinafter described, from the shaft 9, so that
the rotation of the shaft 25, and its cam reciprocates the guide during the rotation
of the spindle and holder. As the spindle and its holder must be turned generally
two or more times to each reciprocation of the guide, the shaft 9, is rotated more
rapidly than the shaft 25, and this is effected through the medium of suitable
intermediate gears. As shown a grooved pulley F, upon the shaft 9, carries a
belt u, passing to a grooved pulley D', upon a shaft 29, carried by an eccentric c,
turning and secured in the split hub 5, of an arm or frame 27, swinging upon the
projecting end of the shaft 25, its weight tending to depress the outer end of the
said arm so as to maintain the belt u taut to prevent any possible slipping.
A detachable pinion 30, on the shaft 29, gears with a detachable toothed wheel 31,
on the shaft 25, and it will be seen that by the use of interchangeable gears 30, 31,
of different diameters, the spindle a may be caused to revolve any desired number

page_text: of revolutions to each reciprocation of the guide, and an increase in the number of
windings does not reduce the speed at which thread is wound. The hub 33 of the
frame 27 is secured detachably to swing freely upon the end of the shaft 25, by a
nut 32, so that the gear 31 can be readily removed and replaced, and as a change
of gears necessitates carrying the axis of the gear 30 from or to that of the
gear 31, the stud 82 of the gear 30 is placed eccentrically on the eccentric C, which
after loosening the screw 81 binding the split hub 5, may be turned to bring the
stud to its desired position.
As before stated however the spindle a must revolve not only a sufficient number
of times to effect the desired number of winds at each rotation of the guide, but it
must also have either a slightly less, or slightly greater, movement so that a point
on the cop which at the end of one reciprocation of the guide is opposite the eye
of the latter, shall at the end of the next reciprocation be a distance beyond or
back of the eye of the guide equal to the distance between two adjacent bends
following each other at the periphery of the cop, thus laying successive coils in
different positions.
In the construction shown, the result is secured by making one of the
pulleys F D an expansion pulley. As shown, the pulley F, is an expansion
pulley, consisting of two discs 79 84 each having one side bevelled with means for
carrying the discs to and from each other, so as to increase or decrease the effective
diameter of the channel in which the belt u (which is triangular in cross section)
lies. A spring 83 tends to separate the discs while they may be brought together
against the action of the spring by turning the dise 84 on the screw-threaded boss
of the disc 79 and securing it by means of a nut 87. To permit these parts to be
readily applied to the shaft the disc 79 has a hub fitting the shaft and secured to
the same by a screw 87* and a thread for the threaded hub of the disc 84, cut on
this hub wheel also receives this nut 87.
By adjusting the discs to increase or decrease the working diameter of the
pulley F, it is not only possible to secure the added or decreased movement
necessary to cause the thread of one coil to be laid beyond that of the other, but it
is also possible to secure the nice adjustment necessary to this end under variations
of operations, resulting from differences in the characters of the threads, and from
different conditions of the same thread under variations in the atmosphere. To
take up any slack of the belt and prevent vibration of the frame 27, an eccentric L,
Figures 6 and 8, is hung loosely on the shaft 9, and is weighted to bear on the
frame 27, permitting the latter to swing outward, but preventing it from swinging
inward.
In order to stop the machine by hand, the lever E¹, is preferably mounted
loosely on the shaft 21, and is provided with two lugs 13 13, the arm 45 projecting
from a hub secured to the shaft 21 having two lugs 13° 13°, a horn 13d, extending
from the arm 42 of the lever E, is in position to make contact with the
projection 13º.
When the handle E', is swung in the direction of the arrow, Figure 7, the
contact of the projection 13ª with the horn 13d swings out the arm 42, of the
lever E, disengages the shoulders 43, 46, and the spring 18, Figure 6, then turns
the shaft 21 and arrests the machine. When the arm is swung in a
direction, the contact of the arms 13 13 rocks the shaft 21 to put the machine in
operation, and swings the arm 45, so as to again engage the shoulders 43 46.
reverse
In many instances it is not practicable to procure cop holders or tubes that are
of regular shape, as they are frequently flattened at one or more parts, or thicker
at one end than at the other, and it has been found that when the guide is pressed
against such irregular holders in building up the cop, it will move in and out as
the projections and recesses are brought opposite to it, and the cop will be started
of an irregular shape which may have a tendency to magnify as the size of the cop
increases. It has been found that this can be corrected by pressing the guide towards
the cop and by permitting it to move freely outward as the size of the cop increases,
and also when any projection of an irregular character is brought beneath it, but

page_text: by preventing the guide from moving inward after being thus forced out by a
projection, so that after the first two or three layers of thread are thus wound, the
cop will assume a regular cylindrical form. Any suitable means may be combined
with the guide for thus permitting it to move outward but preventing it from.
moving towards the cop after it has been moved outward to any extent. As shown.
in Figure 7 an arm 60 extends from the guide carrying frame F, and is provided
with a stud 62, bearing upon the periphery or face of an eccentric cam 64 which is.
pivotted on a stud 66 and has a counterweight 68 tending to turn the cam in the
direction of the arrow so that when the frame F is swung outward to any extent,
the cam 64 will be turned to maintain its bearing with the stud 62, thereby
preventing the frame from swinging inward again. The arm 60 is suitably-
weighted by a weight 61* hung thereto.
Other devices for preventing the inward movement of the guide are shown in
Figure 9. Thus the carriage I of the guide C is shown with a pawl 11 which
engages rack teeth on one of the guides 17 on which the carriage slides to and
from the cop shaft a. Or a carriage C' sliding on a rail 53* is moved by a lever 49
which has a pawl L₁ which engages the teeth of a curved rack bar 9, the lower
end of the lever 49 being connected by a rod 48 with a lever 45 having at the
upper end a plate 50 hearing on the carriage I.
The thread passes from a tension device to a guide 56 Fig. 7, and to the eye of
the guide C and to arrest the motion of the machine if the thread should break, a
stop actuating device of suitable construction is used. As shown the said stop.
actuating device consists of a lever 51 pivotted to the lever E, its longer arm
carrying the guide 56 and its shorter arm having a curved cam face adapted to.
engage the periphery of a slightly eccentric disc 53 on the shaft 9. The draft of
the thread normally holds the lever 51 in the position shown in Figure 7, but if
the thread breaks the shorter arm of the stop lever swings downward, is brought
against the eccentric 53 and the latter forces out the lever 51 and with it the
lever E thus disengaging the shoulders 43 46 when the shaft 21 will be turned by
the spring 18, and the clutch wheel 22 will be drawn back stopping the machine.
It is desirable in many instances to prevent knotted threads from being wound
on to the cop, and a knot-catcher J, Fig. 7, is therefore provided to operate in
connection with the stop device to arrest. the motion of the machine whenever a
knot approaches the guide. The knot-catcher may be of any suitable character;
as shown it consists of a lever 58 pivoted to a pin 61 at the end of the arm 44 of
the lever E and having at the opposite end a fork or notch through which the
thread passes towards the guide 56. At the pivotted end of the lever 58 is a
cam 59, which bears against a set screw 63 extending through a stud on the frame
of the machine, and an adjustable spring 65 tends to hold the lever 58 against any
suitable bearing. When a knot upon the thread is brought against the lower edge
of the lever 58, the latter is lifted, and the cam 59, bearing on the screw 63,.
depresses the end of the arm 44 of the lever E rocking the latter and carrying the
shoulder 43 away from the shoulder 46 so that the stop motion is put into operation
to arrest the movements of the machine.
In winding "doubled" or "multiple" thread upon ordinary cops, the thread is
apt to pile up at one end and sink or catch in between the mass and the bobbin
flange at the other, some strands thus sinking in and others winding onto the larger
part of the cop with the result that some threads are practically longer than
others and the cord or thread made from the multiple thread is irregular. By
winding a series of threads as above described a perfectly uniform result may be
secured.
As illustrated in Figure 10 in winding a series of "doubled" threads together,
the rotating spindle and reciprocating guide apparatus for securing an increment
or decrease of motion are used, but all of the threads are conducted through the
same eye C of the guide, illustrated in Figure 10, but instead of making the eye of
a V-shape, or of a notch which conducts the threads all to a single point, I form
the bottom of the eye in the form of a curve as shown in said figures, so that all.

page_text: the threads, whether there be two or twenty, may lie side by side without one-
piling upon the other. The winding operations then proceed as before indicated
with reference to Figure and the threads are laid all parallel to each other
throughout the cop without any one of the strands piling upon or crossing the
others, although the composite or multiple thread is laid in the same manner as the
single thread, as before described.
The strands or threads from the different bobbins should be fed evenly or
uniformly towards the guide, by passing all of the threads over a roller mounted so
as to turn freely, and covered with felt, cloth, or other like substance to which the
threads will adhere to such an extent that they cannot slip freely thereon. As the
threads all pass over the same roller and the latter moves with the travel of
the thread, all of the threads will be caused to travel at the same rate of speed;
and one cannot pass faster than the other, thus securing a uniform delivery. It is
very important that if one strand breaks, the winding shall cease, or otherwise the
composite cord or thread will be weaker at one point than at another. I therefore
provide any suitable means whereby in the case of the breakage of any strand the
winding device will be thrown out of action.
It has been found that by laying a series of threads side by side in the eye of
the reciprocating guide C, and maintaining a uniform tension and speed of the
thread it is possible to wind them all side by side throughout the whole body of
the cop without overlaying one upon the other, so that when it becomes necessary
to twist together the threads of the cop, they will all be preserved absolutely at
the same tension in unwinding, and the composite cord formed by twisting the
threads together will maintain all the threads in the same spiral condition, and not
as heretofore with some of the threads spiral and others straight.
The machine and method of winding above described may be used for
winding small flat cops such as are used for sewing machine shuttles and in such
case it is desirable to reduce the labour in pressing the cops to fit the shuttles and
in boxing them after pressing. To this end the machine illustrated in Figures 11
to 17 is used.
The frame of the machine is constructed to support the operating parts, which
are driven from a shaft S, to which rotation is imparted in any suitable manner,
the gears operated by the said shaft being contained within a gear casing J.
The cops that are to be compressed and boxed are deposited in the successive
sockets of an endless chain A, which passes around the chain wheels Bat
opposite ends of the machine these wheels being turned with a step by step or
intermittent motion.
The travel of the chain brings each socket and the cop therein contained
between the dies 7 8 Figure 13, of a presser device C, the said dies having concave
faces which impart a convex contour to each side of the cop, as the dies are
brought together, this movement occurring during the time that the chain A, is
at rest.
To
The cops are then carried through a chute or channel e Figures 11 and 12, to the
lower end of the channel c, and opposite one of the spindles or pins 30 of a con-
tinuous chain E, consisting of two parallel chains of links connected by the shanks
of said spindles, and supported upon chain wheels ff carried by shafts 20, 32.
this chain E an intermittent motion is imparted, and each spindle 30, is brought to
rest opposite a socket v (Fig. 14) in the channel c in line with the centre of the
said socket, so that each cop will come to rest with its centre opening in line with
one of said spindles.
A reciprocating pusher 40, Figures 12, 14, is carried inward after a cop is
brought into position and pushes the said cop onto the opposite spindle 30, and the
next cop that is brought into position is also pushed onto said spindle, pushing that
ahead of it further onto the spindle 30, and so on until twelve cops are upon the
spindle 30.
The chain E, then moves forward one step to bring the next vacant spindle 30
opposite the socket when these operations are repeated.

page_text: A box X Figure 13 adapted to receive one gross of cops is placed upon a table e
carried by a frame I which can be raised and lowered to the different positions
shown in Figures 12 and 13 and normally occupies the lower position, as shown in
Fig. 12. When twelve spindles 30 each with a dozen cops upon it, are above the
box X an alarm is sounded and the operator then raises the frame I, to the position
cops within
shown in Fig. 13 (full lines) thereby bringing the lower parts of the
the box, and he then draws out the frame I, in the direction of the arrow Fig. 13,
and thus strips the cops off of the spindles, when they fall into the box in proper
position.
The cops are thus pressed sorted into lines of a dozen each, and twelve dozen
are deposited into the box automatically so that all the operator has to do is to put
the boxes into place and to remove them from the machine.
Any suitable means may be employed for imparting the various movements to
the parts described.
As best seen in Figure 13 the die 7 has a threaded stem so as to be detachably
secured in a threaded sleeve 9, which fits an opening in the frame whereby on
turning the said sleeve (which has a square head, as shown in Figure 12) the said
die 7 may be set properly in its position.
The die 8 screws into a sleeve 13 which slides in the frame and has at its end, a
flange which bears on springs 14 which tend to throw the die towards the left of
Fig. 13.
Through the sleeve 13 reciprocates a rod 12, having a shoulder y, and a pro-
jecting centering pin 10 so that as the rod 12, moves towards the right, the
pin 10, first goes through the central opening in a cop, and then the shoulder
comes against the end of the die 8, and carries the latter and the sleeve 13 with it,
until the cop is compressed.
y
Reciprocation is imparted to the rod 12, by means of a stud 17, upon a cam
wheel 19, carried by a shaft T, the said stud extending into an inclined groove u in
a bearing plate 16 secured to the rod 12.
The step-by-step motion is imparted to the chain A, from a swinging frame 21,
pivoted to the frame of the machine and carrying a roller bearing 22, that bears
upon the edge of the cam wheel 19, that lifts the frame 21 once at each revolution
of the shaft T, a pawl 24 (Fig. 15) connected with the frame 21 engaging a
ratchet wheel 28, upon the shaft 26 that carries the forward chain wheel B.
A check pawl 23 prevents any return movement of the wheel 28 and its connecting
parts.
The pusher 40 is also operated from the cam 19 which bears against a roller 34
(Fig. 13) on a lever 33 extending from a rock-shaft 35, and an arm 36 at the
forward end of the said rock-shaft extends between two collars 37 (Figs. 15 16)
on a rod 38 having at one end an arm 39 from which extends the pusher 40.
A spiral spring 60 throws the rod 38 and the pusher in the opposite direction.
The step-by-step motion of the chain E, carrying the spindles 30 is effected by
means of a reciprocating pawl 27 (Fig. 15) hanging from one arm of a rock
sleeve 26 (Fig. 14) the other arm of which is connected by a rod 25, with the
frame 21, so that the chain E, can only be moved at the time of one of the move-
ments of the chain A, to feed forward a cop into the socket ; the projection of
the cam wheel 19 acting on the stud 34, of the arm 33, to move the pusher 40 after
these operations have taken place.
It will be evident however that the chain E is only to be moved after one
of the spindles 30 has received a dozen cops and means are therefore provided for
normally holding the pawl 27 out of contact with the sbank of the spindle 30
with which it would otherwise engage, until one of the said spindles is filled with
cops.
As shown a sliding bar or shaft 61 (Figs. 12 and 17) carries an arm 51 having a
lipt which is normally beneath and lifts the end of the pawl 27, so that the latter
cannot engage with the shauks of the spindles 30. The shaft 61 also has a stud or
B

page_text: projection 50, in such position that as a spindle 30 becomes filled with cops, the
side of the innermost end cop will come in contact with the said stud 50, and as
the last or twelfth cop is placed upon the spindle 30, the inner cop will by its
contact with the stud 50, push the latter and the shaft 61 so as to carry the arm 51,
and is lip away from the pawl 27. The next reciprocation of the frame 21 will
then bring the end of the pawl 27 into contact with the shank of a spindle 30, aud
turn the chain E, one step bringing the next empty spindle opposite the pusher 40.
As the spindle with its cop is carried downward, the cop in contact with the
stud 50, passes below the latter and a spring 62 (Fig. 17) then acts to carry the
rod or shaft 61, in the direction of its arrow Fig. 17, and again bring the lip of
the arm 51 in position to prevent the further contact of the pawl 27 with the
shanks of the spindles until the above described operations are repeated.
When twelve of the spindles are filled with cops, as above described, a cop upon
that one of the spindles 30 Fig. 11 nearest the curved arm 43 will be brought
against it, and as it is pivotted on the shaft 20, the said arm will be raised so as to
make contact with a stop 42, the arm and stop being connected with the terminals
of a circuit V, including a battery G2 and an alarm bell F2, so that the ringing of
the latter will announce to the attendant that there is a gross of cops in position
above the box X. The side bars of the frame 1 have slots n through which
extends the supporting bar 45, the table or platform being provided with an
adjustable gauge 46 against which the box X is set and when a box is to be filled,
the attendant raises the frame I, brings the box into position to receive the lower
portions of the cops, and then by simply drawing the frame forward on the bar 45
he carries the cops successively off of the spindles 30 and they drop into the box.
He then removes the filled box places an empty box against the guide 46 and
pushes the frame back into the position shown in Fig. 13 when the above described
operations are repeated.
Having now particularly described and ascertained the nature of the said
invention, as communicated to me by my foreign correspondent, and in what
manner the same is to be performed I declare that what I claim is ;-
