ALGERNON DEWHURST, OF SKIPTON, ENGLAND.

MACHINE FOR WINDING THREAD.

SPECIFICATION forming part of Letters Patent No. 586,428, dated. July 13, 1897.

Application led October 25, 1895. Serial No. 566,932. (N0 mdel-l Patented in England May 6, 1885, No. 5,609.

T0 all Inh/0771, it mn" concern' Be it known that I, ALGERNON DEwHUEsT, a subject of the Queen of Great Britain and Ireland, residing at Skipton, in the county of York, England, and a director of John Dewhurst @s Sons, Limited, cotton-spinners and sewing-cotton manufacturers, have invented certainImprovementsinMachineryforWinding Thread or the Like, of which the following is a specification.

My invention relates to machines for winding thread or the like into coils, cops, or cylinders or onto bobbins, spools, or tubes or the like, and more particularly to machines in which the thread or the like is wound in spiral form of coarse pitch-that is, with what is known as a quick traverse-and in which the speed of the traverse is caused to bear a uniform ratio to the speed of the windingspindle by means of regulating devicesfor example, by change-Wheels such as are employed in the machines for which Letters Patent were granted to me in Great Britain, dated 6th day of May, 1885, No. 5,609, or in which the speed of the traverse as compared with that of the winding-spindle is caused to increase as the coil increases in diameter; and my invention has for its object to provide means whereby the thread can be traversed to and from one extreme end to the other end of the cop, coil, cylinder, or the like Without any vibrating or reciprocating movement of the thread-guide, thereby reducing wear and tear. l provide a rotary thread-guide in combination with means for giving to the said guide a rotary movement by positively driving it from the same source as that from which the winding spindle or spindles is or are driven. Y

I will describe my invention as applied to machines for winding coils or cylinders of thread such as are described in the specification to the Letters Patent hereinbefore referred to, from which its application to other machinery of a similar kind will also be readily understood. In this machine two l spindles, which l call the front77 and back winding-spindles, are employed arranged in axial line one with the other and having cheek-pieces thereon between which the coil of thread is wound upon the reduced end of one of the said spindles.

spool, or bobbin on which it is to be wound.

by the aforesaid rotary thread-guide, the end ot' the thread being secured to the said spindle, tube, spool, or bobbin by any suitable retaining device, so as to cause the thread to be wound on the said spindle, spool, or the like when the spindle rotates. The said thread-guide consists of a disk or cylinder in one or more parts having in its periphery a cam groove or space so shaped that the thread which is placed therein is by the rotation of this disk or cylinder (without any longitudinal movement being given to t-he said disk or cylinder) caused to traverse to and fro from end to end of the coil and to lay the consecu- Irive spirals of thread parallel and close tolget-her. The thread-guide is mounted on a short spindle carried by an arm (or by arms `rigidly connected together) loosely mounted on a counter-shaft arranged parallel to the winding-spindles. The arm or arms may be connect-ed by means of levers and connectingrods or by eccentrics or by levers, connectingrods, and eccentrics to a loosely-revolving presser arranged to bear on the coil as it is being Wound, which presser by being connected to the thread-guide maintains the said thread-guide at a suitable distance from the coil as it is being made, the connection being such that as the coil increases in diameter and forces the presser farther from the axis of the winding-spindle the thread-guide will ,be moved correspondingly away from the axis of the said Winding-spindle.

For operating the rotary parts of the machine any suitable arrangement of gearing may be employed, and change-wheels or other convenient means may be provided for varying, as required, the relative speeds of the Vthread-guide and Winding-spindles.

A suitable arrangement of driving-gear consists as follows: On the winding-spindle is a pulley round which passes a driving -strap from any suitable motor. The winding-spin- IOO wheels by which motion is transmitted from the winding-spindle to the counter-shaft are chan ge-wheels, so that wheels of suitable sizes may be fitted to vary the speed of rotation of the thread-guide with relation to the speed of rotation of the winding-spindle, so as to cause the t-hread to be moved to and fro from end to end of the cop, spool, or cylinder of thread or the like in such a manner that whatever may be the thickness of the thread or the like to be Wound each right-hand spiral can be laid in close juxtaposition to the preceding right-hand spiral, and each left-hand spiral can be laid in close juxtaposition to the preceding lefthand spiral'.

In order that my invention maybe clearly understood, I shall further describe the same with reference to the accompanying drawings.

Figure 1 is a side elevation, and Fig. 2 a corresponding plan, of a hand winding-machine constructed according to my invention for making one coil, cop, or cylinder at a time or for winding onto one bobbin, spool, or tube at a time. Fig. 2A is a plan of the contiguous ends of the two winding-spindles. Fig. 2B is an elevation of a modified form of cheekpieces employed in winding thread or the like onto bobbins or spools. Fig. 2C is a face view of one of the said cheek-pieces, and Fig. 2D is a side view of a spool to be Wound. Figs. 8 and 4 are elevations of the two ends of the machine; and Fig. 5 is a transverse sectional elevation made on the line 1 2, Fig. 2. Figs. 6 and 7 are respectively a front elevation and a corresponding plan of a hand winding-machine for winding one cop at a time upon oneend of a single winding-spindle without the use of cheek-pieces. Fig. 8 is a front elevation with parts of the various shafts or rods broken away and portions of the apparatus removed to show more clearly the thread-guide and the winding mechanism of a self-acting machine of the lVeild type for winding several cops, coils, spools, or the like at one time; and Fig. 9 is a transverse sectional elevation taken on the line 3 4, Fig. S,

the divided cap or cover of the thread-guide removed and all the distant parts of the machine omitted, the thread-hook, stationary cutter,and spring-plate for securing the end of the supply-thread being shown in this iigure in their usual position and those parts of the machine which for convenience are in Fig.. 8 broken away being in this figure shown in section. Figs. 10 and 11 are respectively a front elevation and a transverse sectional elevation of a portion of the machine, showing more clearly the thread-guide with its divided cap or cover, the thread-cutter, and th read-retaining device, also the sloping delivery trough or chute, Fig. 11 showing also the position of the winding spindle; and Fig. 12 represents a plane projection of the cams, showing the relative positions of the cam-surfaces for effecting the various motions hereinafter described.

Figs. 13, 14, and 15 are respectively a-side elevation, a plan, and an end view of the principal parts of a winding-machine constructed substantially in the same manner as that described with reference to Figs. 1, 2, 2A, 3, 4, and 5, but on a much smaller scale, so as to render it suitable as an attachment to a sewing-machine- The hand-machine represented by Figs. 1, 2, 2A, 8, 4, and 5 may be used for winding thread or the like into coils, cops, or cylinders or the like either with or without central tubes, and may be bolted or otherwise fixed upon an ordinary table for hand-spooling, and may be driven from any suitable prime mover by means of a strap or tape passing round the wharve or pulley a, fast on the front winding-spindle A, which is fitted to rotate in bearings Z) in the frame B of the machine.

In axial line with the spindle A is mounted in bearings h2 the back winding-spindle A2, which is driven at the same speed as and from the front spindle A by means of the gearing C and shaft D. One end of the back spindle A2 is reduced in diameter, as shown at CL2, to correspond to the size of the hole or passage to be left in the center of the coils or rolls of thread to be formed on which reduced portion, which may, if so desired, for winding upon tubes be constructed with expandingsprings or other expanding apparatus. The thread is wound between two cheek-pieces, collars, or heads E E2, mounted, respectively, on the adjacent ends of the front and back spindles. These cheek pieces, collars, or heads are tted so as to rotate with their spindles. The cheek-piece E2 is provided with a hole or passage in its center, through which hole the reduced portion d2 of the spindle A2 projects and enters a recess in the face of the cheek-piece E, the distance between the faces of the two collars or cheek-pieces being equal to the thickness or length of the coil or roll of thread to be formed.

G is a thread-guide which consists of a disk\ having in its periphery a cam groove or spac g5 to receive the thread to be wound. guide is fast on a spindle or shaft H, mounted in bearings 71y in arms h2, connected together by a bar h2, so as to form a rigid frame, which frame is mounted loosely on a shaft H2, arranged parallel to the winding-spindles A A2, and mounted in bearings h4 in the frame B, and a bearing h5 in a bracket h6, bolted to a plate B2, secured to the said frame.

The spindle or shaft H and the shaft H2 are connected together by gearing h2'. On the shaft H2 is a spur-wheel h2, gearing with a broad carrier-pinion h2, mounted loosely on a stud hw on an adjustable bracket 7L, bolted to the fra-me B of the machine. ,i

Gearing with the broad carrier-pinion hi is a spur-wheel k12 on the front winding-spindle A. The wheels hs k12 are change-wheels, whereby the relative speeds of the windinge This) IOO IIO

spindles A A2 and the spindle or shaft H, carrying the thread-guide G, may be varied as required.

K is a disk preferably of slightly greater diameter than the thread-guide G, the said disk being carried so as to rotate on an axis k2 in arms 1&4, fast on a rocking shaft K2, mounted in a bracket 76"", bolted to the frame B, and in a bracket k, bolted to the plate B2. On the shaft K2 is also fixed another arm i3, provided with a handle t4, by means of which the shaft may be turned in its bearings in the brackets k2' 7a2, so as to cause the disk K to press on the thread as it is being wound on the reduced portion a2 of the spindle A2. The length of the arms k'l from the center of the disk or presser K to the axis of the rockshaft K2 is the same as that of the arms h2 from the center of the thread-guide G to the axis of the shaft H2, the position of the rockshaft K2 being such that it and the shaft H2 are equidistant from the axis of the windingspindle.

Connected to the frame h2 h3 is an arm t", hinged at t to one end of a rod or bar t7, the opposite end of which rod or bar t7 is, by means of a stud forming part of the handle t", connected to the arm i2 onthe shaft K2. The length of the arms t2 and are equal to one another, and the length of the connecting bar or rod l is equal to the distance between the axes of the shafts H2 and K2. Thus it will be seen that the imaginary lines K2 2, fr* fi, i6 H2, and H2 K2 form a parallelogram and that the arms and connections of which three sides of it are composed move together in such a way that the angle H H2 A is always equal to the angle k2 K2 A, so that as the disk or presser K is moved farther from the axis of the winding-spindle by the coil of thread as the said coil increases in diameter the thread-guide G will be correspondingly moved farther from the said spindle and so during the winding process be constantly kept just out of contact with the coil.

In order to insure great accuracy of the movement of the presser and the threadguide to and from the winding-spindle, I prefer to apply an additional connection between the shafts H2 and K2, the said connection consisting of an eccentric 'i12 on the frame h2 h2, of which eccentric the strap 14 forms part of a connecting-bar 15, which at its other end forms also the strap t of another eccentric t, fast on the rock-shaft K2, the lines of greatest throw in the two eccentrics being parallel one to the other and pointing in the same direction.

f2 is a hand-wheel fast on a screwed stem F2, working in a stationary nut or internallyscrewed boss F4, formed on the plate B2, bolted to the frame B. On a plain or unscrewed part of this stem is loosely mounted between the boss of the wheel f2 and a collar on the said stem an arm Fi", provided at its upper end with a hollow boss f3, in which the outer end of the back winding-spindle A2 rotates.

vIn the portion of the spindle which enters the hollow boss f2 is formed an annular groove or recess, with the sides of which engages the end of a set-screw f4, screwed through the side of the said hollow boss. The engagement of this set-screw with the sides of the annular groove or recess causes the said spindle to move longitudinally with the movement of the screwed stem F3 and arm E5, but nevertheless ad mits of the rotation ofthe spindle in the said boss f2. The distance to which the back spindle A2 can be moved longitudinally is governed by the head of a stud f5, which stud passes through a hole in the arm F5 and screws into the plate B2, the distance to which the stud is made to project beyond the arm F5 regulating the extent of the 10ngitudinal movement of the spindle. On the spindle A2 is provided a longitudinal groove 7"5 (see Fig. 2A) to receive a key f7, fixed in the interior of the cheek-piece E2, so as to cause the said cheek-piece to revolve with the said spindle, although admitting of the longitudinal movement of the said spindle in the said cheek piece. The cheek-piece E2 is moved away from the cheek-piece E by the outward longitudinal movement of the spindle A2 until the rear end of the said cheekpiece E2 comes into contact with a shoulder f8 in the interior of the bearing b2, whereupon the movement of the cheek-piece is arrested and the spindle, by its continued movement, draws the reduced end a2 thereof into the cheek-piece E2, and so releases from the machine the coil of thread when wound.

In commencing to form a coil or roll of thread the thread from the thread-supply is laid in the cam groove or space g5 of ther thread-guide G, and the end of the thread is secured between the contiguous ends of the front and back spindles A A2. The threadguide G is then by means of the handle i4 brought into position between the cheekpieces E E2. The machine is then started in the ordinary manner by friction gearing worked by a treadle or otherwise, whereupon the spindles A A2 will rotate and wind the thread upon the reduced portion d2 of the back spindle A2. Vhen the coil has reached the required diameter, the thread-guide is removed froln between the cheek-pieces by means of the han die/4, the thread is severed, the cheek-pieces E E2 are separated one from the other by means 0f the hand-wheel f2, and as the motion of the hand-wheel is continued the reduced end of the spindle A2 is withdrawn from the center of the coil,which, being released, falls from the machine into a suitable receptacle.

Figs. 6 and 7 illustrate a modiiied form of the machine hereinbefore described and in which modiied machine the' use of the back winding-spindle and its cheek-piece is dispensed with, and the cheek-piece E is fitted to slide longitudinally on the spindle A for the purpose of forcing from its reduced end d2 the coil of thread or the like when wound.

The sliding movement of the cheek-piece E is effected by means of a lever-handle F2, hinged at f8 to the base of the'machine, the said lever being connected by a link d2 to a sliding bar F6, provided witha projection f, which engages the sides of an annular groove or recess formed for the purpose in the periphery of the cheek-piece E, so that by moving the lever-handle F2 in one direction or the other a corresponding movement can be imparted to the said cheek-piece. The bar FG slides in an opening provided for the purpose in the frame B.

In the arrangement illustrated by Figs. 6 and 7 the brackets h6 and 7c are shown at- I tached to a portion of the framework B, which lfirst described.

is for the purpose carried up somewhat higher than usual.

Referring to Figs. 2B and 2C, which illustrate a modification in the construction of the cheek-pieces and of the contiguous ends of the winding-spindles A A2 for winding thread or the like onto spools, one of which is illustrated by Fig. 2D, the contiguous faces of the cheek-pieces E E2 are respectively formed with recesses z z2 to receive the correspondingly-shaped ends of the spool upon which the threadv is to be wound. In the sides of the aperture in the center of the cheek-piece E2 are one or more longitudinal slots 22 to admit of the passage of one or more projections z2, provided on the spindle A2 for the purpose of engaging with the surface of one end of the spool to insure its rotating along with the winding-spindles.

Althoughin the drawings,Figs. l, 2, 2, 2B; 2C, 3., l, and 5, I have illustrated an arrangement wherein the cheek-piece E2 and the spindle A2 receive longitudinal movement, I do not restrict myself to this arrangement, as it is obvious that the cheek-piece E and spindle A may be arranged to move in place thereof or in combination therewith.-

The self-acting machine of which Figs. 8 to 12 show certain portions is one of the Weild type modified in several respects, as described in the specification to the Letters Patent hereinbefore referred to.

In applying my invention to self acting machines I may arrange any desired number of spindles in one machine and rotate them from one driving-shaft. I have, however, shown in Fig. 8 of my drawings only one pair of spindles, and in orderto prevent unnecessary complication I have omitted from the drawings various details and parts common to such machines, but which are or may be used in combination with my improvements.

Referring to Figs. S, 9, IO, and 1l, B is aportion of the framework of the machine. A A2 are respectively the front and the back winding-spindles, rotating, respectively, in bearings b 792 and fitted with collars or cheek-pieces E E2, as in the hand-machine hereinbefore a2 is the reduced portion of the front spindle A, upon which I prefer, in the case of a self-acting machine, to wind the coil or roll of thread or the like; D, thedriving-shaft; G C, the gearing for rotating the winding-spindles; G, the rotary thread-guide;

H, the spindle or shaft which carries the `rigid frame is loosely mounted; 71,4, the bearings of the shaft H2 in the framework B and B3; 71,7, the gearing which connects the shaft H2 with the spindle or shaft H; 71,8, the spurwheel onV the shaft H2, gearing with a carrierpinion hg; hw, the stud which carries the said pinion; 71,11, the adjustable bracket by which the stud 71,10 is attached to the framework Ba ofthe head-stock at the end of the machine; k12, awheel upon the driving-shaftD,by means of which motion is imparted to the carrierpinion 71,9 and through it to the spur-wheel 71,a and the guide G, the wheels hs 7112 being chan ge-wheels, whereby the relative speeds of the winding-spindle A and the spindle or shaft H, carrying the thread-guide G, maybe varied as required; g5, the cam groove or space to receive the thread to be wound; g, a divided cap or cover which I prefer to place over the rotary thread-guide in order to prevent the thread from slipping 0E it sidewise while the spindles are stationary, the said cap or cover being attached to the rigid frame h2 71,3 by means of screws Q7 or by some other convenient device; K, the presser which acts upon the thread while it is being wound upon the reduced portion co2 of the drivingspindle A; 753, the axis on which the presser K revolves; 7a4, the arms which carry the presser K, the said arms being fast on the rock-shaft K2, which I prefer, in the case of a self-acting machine, to make hollow and to mount loosely upon the sliding rod 2v2, a portion of the said rock-shaft being cut away, as shown in Fig. 9, to allow sufficient room for the horizontal movement of the hooked Wire 102, which is also mounted on the rod w3, and to allow the rock-shaft to make a partial revolution without its coming in contact with the hooked wire. i3 is the arm which in the case of the hand-machine hereinbefore first described is provided with a handle, but which in the case of a self-acting machine need not be so provided; i5, the arm connected to the frame 71,2 h2.

i7 is the bar which forms the connecting-rod between the arms 'i3 and 155, which bar carries at one end a stud i4, by means of which it is hinged to the arm i2, the said bar being at its other end hinged to the arm 'i5 by means of a stud 1,'6 and also to a link is, the forked end of which carries the aforesaid stud 11"', there` being in the underneath portion of the said link is a curved notch or opening i9, (shown in dotted lines in Fig. 9,) the curve of which notch has the stud G for its center, and the said notch engages a stud il, carried by the IIO forked end of an arm 11, fastened by a setscrew to the shaft 12, the connection being such that when the aforesaid notch is engaged with the aforesaid stud the presser, and along with it the guide, can, by a partial revolution of the aforesaid shaft @'12 in one direction,.be moved away from the winding-spindle, or can, by the shaft being permitted to make, under the action of the customary spring or weight, a partial revolution in the opposite direction,

be moved closer to the winding-spindle, and

when the link is is raised so as to disengage the notch @'9 from the stud @'10 the presser and the guide can be moved by hand to facilitate the piecing of a broken thread, or for any other purpose; @'12, the eccentric on the rigid frame h2 h2; @'14, the strap of the said eccentric; @'17, the eccentric on the rock-shaft K2; @'16, the strap of this latter eccentric; @'15, the connecting-bar between the two eccentrics.

Gearing with the spur-wheel hs there is, in addition to the carrier-pinion already described, a second carrier k12, mounted upon a stud h11, attached to an adjustable bracket h15, which is bolted to the framework B2 of the head-stock at the end of the machine. Gearing with the said second carrier 71.13 is a spur change-wheel 7L16, mounted upon the shaft P2, which, as is customary in Weilds self-acting spooling-machines, is made with right and left hand screws upon it for traversing the Shaper-finger backward and forward across the Shaper-plate. The Shaper-plate and the shaper-nger, which are not shown in my drawings, are made like those in other machines of the Weild type; but, as in this machine there is not a traverse-rod for the sliding rocker P3 to operate, it is mounted loosely upon the shaft H2, the position of which in the head-stock is, in order to suit the arrangement of the other portions of the machine, somewhat lower down than the usual position of the traverse-rod in ordinary machines, the rocker-arms P4 being correspondingly longer than usual and the Shaper-plate being placed somewhat lower than customary in order that it may be upon a level with the center of the shaft H2, and consequently on a level with the axis of the rocker P2.

From the sliding rocker P3 is actuated the second rocker P5,to which is attached the usual pawl P6, which actuates the ratchet-wheel P7 (shown in dotted lines in Fig. 8) and thus causes the ratchet-wheel shaft P to gradually rotate with an intermittent motion while the winding is in progress. The wheel h16being, as already described, a change-wheel, it is possible by means of it to regulate the speed at which the screw-shaft P2 rotates, and consequently the number of times that the shaperfin ger traverses across any given Shaper-plate for a certain number of revolutions of the shaft H2 and for a certain number of revolutions of the driving-shaft D.

As is customary with machines of the XVeild type, each time the Shaper-finger makes a backward-and-forward movement across the Shaper-plate the pawl P6, attached to the rocker P5, moves the ratchet-wheel forward one tooth, and when the last tooth is being acted upon the winding portion of the machine is brought to a standstill and the cam portion for performing the other operations is set in motion. The shaperplate being changeable, also to a limited extent adjustable, and .the ratchet-wheel PT and the spurwheel hw being change-wheels itis possible by selecting a Shaper-plate of the right form and wheels with the requisite number of teeth to regulate the number of revolutions that the winding-spindle makes during the winding of each cop or the like, and consequently the length of thread wound.

k is a loosely-revolvin g presser situated beneath the winding-spindle and supported by a forked stem la, the said presser being under the action of a spring k2, operating upon the said stem, brought into contact with the coil of thread or the like after it has been wound and for the purpose of squeezing down upon its surface the loose end of thread after the severing of the coil from the thread-supply. For the purpose of holding the presser out of action until it is required to press upon the 1 coil there projects from stem kf" a stud k6, carrying a bowl k7, which is acted upon by a wedge-shaped block las, mounted upon the sliding rod k2, which is operated by cam No.5.

Further, as described in the hereinbeforementioned specication, e2 are the rounded nicks in the collar or cheek-piece E 5 e1, the spring catches or clips arranged around the said collar or cheek-piece; L, the hook which during the winding process disengages from the clip the starting end of the thread Z2 on the cheek-piece; E, the groove into which the hook enters; m2, the spring acting upon the said hook; m2, l[he wedge-shaped block for withdrawing the said hook; m4, the sliding rod upon which the block is carried; m5, the friction-bowl, against which the said block presses; m.6,the stem of the hook,to which stem the said bowl is attached; m2, the spring, by means of which the sliding rod 'm4 and the wedge-shaped block upon it are brought back into their normal position after having been operated by the cam on the ratchet-wheel shaft; H, the hook, which engages the thread between the coil and the th read-supply; N, the spring-plate, between which and ,the said hook the thread is drawn; O, the stationary cutter on the opposite side of the said hook; the instrument, by means of which the finishing end of the thread is disengaged from the rounded nick c2 and laid snugly upon Ithe periphery of the coil; x2, the annular groove which is made in the circumference of the collar or cheek-piece E and into [which the instrument :c descends; d4, the rod for operating the cheek-pieces; cl3, the link, through which the said rod acts; F2, the lever acting upon the cheek-piece E; F, the lever acting upon the cheek-piece E2; d and cl2, the thrustpieces, by means of which the cheek-piece E2 TOO IOS

receptacle; c, the helical spring, under the action of which the cheek-pieces return' to their normal position ready for winding a fresh cop or the like and which keeps the cheek-pieces in that position during the winding process.

Referring to Fig. 12, No. l shows in plane projection the cam for moving the rotary guide and the presser connected to it away 'from the winding-spindle after a cop or the like has been wound and for causing the said guide and the said presser to enter the space between the two cheek-pieces when the machine is preparing to wind a fresh cop.

No. 3 shows in plane projection the cam for raising the hook M, so that it will be in readiness to catch hold of the thread as soon as the said thread has, by means of the hooked wire wg, been drawn across the path of the said hook M.

No. 4L shows in plane projection the cam for causing the instrument @c to enter the groove :r2 and to turn the end of the thread onto the surface of the cop, so that when the few additional revolutions which I prefer to impart to the cop are inprogress the end of the thread will be neatly pressed down upon the periphery of the cop.

No. 5 shows in plane projection the cam for actuating` the small compacting-presser 7o, which is only brought into play after the cop has been formed and just before the commencement of the few eXtra revolutions which I have referred to.

No. 6 shows in plane projection the cam for causing the cheek-pieces E E2 to slide endwise along their respective spindles A A2 in order that the finished cop may be forced off the winding-spindle.

No. 7 shows in plane projection the cam which causes the hooked wire L02 to draw the thread within reach of the hook M after each cop has been wound.

in commencing to wind a coil or the like the thread from the supply-bobbin is passed under the shaft @'12, then laid inthe nick or space between the two portions of the divided cover g, then drawn across the end of that half which is nearest to the cheek-piece E, thence into one of the rounded nicks c2 in the collar or cheek-piece E, and the end of the thread is secured beneath one of the spring catches or clips e4, arranged around the collar or cheek-piece E. The thread having been thus secured to the cheek-piece E the winding mechanism is started, and as the spindles A A2 and the guide G rotate the thread is drawn into the cam groove or space g5 in the periphery of the guide G and is wound upon the reduced portion a2 of the winding-spindle A, being traversed rapidly to and fro frornon'e side of the opening between the two cheekpieces to the other side of it by means of the cani groove or space g5 in the periphery of the rotating guide G, each right-hand spiral of, thread after the first half-revolution of the guide, if made with a double traverse, as shown in my drawings, being parallel to the preceding right-hand spiral, the two being either in actual contact with one another or at a certain distance apart, as maybe required, and each left-hand spiral of thread after 'the first half-revolution of the guide, if made with a double traverse, being parallel to the preceding left-hand spiral, the proximity of Y the two corresponding with that of the righthand spirals and being regulated by means of the change-wheels hs and k12, which are made use of to determine how many revolutions the winding-spindle shall make for each revolution 'of the rotary guide. After the winding-spindles have made a number of revolutions the detaching-hook L, actuated by the usual cam on the ratchet-wheel shaft, enters the groove Z2, engages the thread be` tween the rounded nick c2 and the springcatch e4, thereby pulling the starting end of the thread from the hold of the said springcatch and setting free the starting end of the thread. Having performed this operation, the detaching-hook L is permitted by its cam to return under the action of the spring m7 to its normal position. Vhen the cop has acquired the requisite diameter, or when the required length of threador the like has been wound, the winding portion of the machine is stopped in the ordinary way by the escape plate or disk in the head-stock of the Inachine being liberated and allowed to make a partial revolution, the Shaper-plate and ratchet-wheel in the head-stock having, as previously explained, been so arranged as to bring this about at the right moment. The cam-shafts being at the same moment and by the same movement of theescape-plate set in motion, the rotary guide, and with it the presser K, are removed from between the cheek-pieces. The hooked wire @u2 then passes between the rotary guide and the coil-nick, engages the thread between the two, and draws the said thread aside into the path of the hook M, by which it is drawn down against the spring-plate N on one side of the hook and against the stationary cutter O on the other side of the hook, the stationary cutter severing the thread on the coil from the threadsupply and the spring-plate retaining hold of the severed end of the supply-thread. The coil having been thus severed from the threadsupply, the winding mechanism may be, as described in the speciiieation to the Letters Patent hereinbefore referred to, set in motion, the loosely-revolving presser /c having been previously brought into contact with the surface of the coil and the instrument a; having been caused to descend into the groove x2;

ICO

As soon as the winding-spindles begin to revolve the saidinstrument engages the iin-V ishing end of the thread, pulls the said thread out of the rounded nick c2, and lays it snugly upon the surface of the coil, whereitis pressed down by coming as the cop revolves in contact with the presser k. The winding-spindles after having made a few revolutions may, as described in the specification to the Letters Patent hereinbefore referred to, be again brought to a stand and the cam-shafts be permitted to complete the revolution which was interrupted. The continued movement of the cam-shafts causes the presser k to return to its normalA position and the cheek-pieces to slide along their respective winding-spindles, thereby pushing the cop off the small end a2 of the winding-spindle A and allowing it to drop down the sloping trough or chute, the hooked wire and the instrument fr having in the meantime returned to their normalposition. As the cams continue to rotate the cheek-pieces return to their normal position, the thread-guide G, and with it the presser K, enter the space between the said cheekpieces, the driving-belt is thrown onto the winding-pulley, and the winding-spindles are set in motion, one of the spring-catches c4 having as the winding-spindles began to revolve engaged the starting end of the thread between the rotary guide and the point where it was held by the spring-plate N and pulled the said thread away from the hold of the said spring-plate. The end of the thread being retained by the spring-catch e4, the said thread is carried round by the winding-spindle as it rotates, and the winding of a fresh cop commences.

In the machine represented byFigs. 13, 14, and l5 the parts corresponding to those in the hand-machines previously described are designated by the same reference-letters. It will be observed, however, that in this arrangement the back winding-spindle is omitted, and the cheek-piece E2 is attached to the spindle A by a screw e5, projecting from its center and screwing into the reduced end CL2 of the spindle A, and is provided with a milled knob or handle c5 for convenience of placing in position and withdrawing the said cheek-piece and removing from the spindle the coil when wound. It will also be observed that in place of the wharve d in the previouslydescribed machine a small friction-pulley a is substituted therefor, which by turning the whole machine on its supporting-pivot b3 can be brought into contact with the fly-wheel or other suitable rotating part of the sewingmachine, so as to drive the winding mechanism.

It will further be observed thatin place of change-wheels for varying the relative speeds of the thread-guide and the winding-spindle a pair of cone-pulleys hs k12 is provided for the purpose.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isl. In machines for winding thread or the like, the combination of a rotary threadguide having a cam groove or space in its periphery to receive the thread to be wound, with means for rotating said thread-guide and means for maintaining the said guide at a uniform distance just clear of the surface of the coil or the like as it is being Wound, substantially as hereinbefore described.

2. In machines for winding thread or the like, the combination with the Winding-spin- 8o dle, of the rotary thread-guide having a cam groove or space in its periphery to receive the thread to be wound with a disk or presser,with means for rotating the thread-guide and arms so connecting the threadguide -to the said disk as to constitute a parallel motion whereby as the presser is moved outward from the winding-spindle by the coil of thread or the like as it increases in diameter, the threadguide is simultaneously moved out from the windingspindle in the same proportion so as to retain the said thread-guide out of contact with the coil, substantially as hereinbefore described. f

3. In machines for winding thread or the like into coils, or the like, the combination of a winding-spindle and mechanism for positively driving the same, with a rotary thread-. guide having in its periphery a cam -groove i or space to receive the thread, mechanism for positively driving the thread-guide, and change wheels connecting these driving mechanisms, whereby the speed of the threadguide is caused to bear a uniform ratio to the speed of the winding-spindle, and such ratio that each spiral of thread will be laid in close juxtaposition to the preceding spiral, no matter what thickness of thread is being wound, all substantially as hereinbefore described.

In testimony whereof.` I have signed my name to this specification in the presence of two subscribing witnesses.
