- the machine is now ready to start and it may be assumed that the driving shaft 25 is rotating. Under these conditions it is only necessary to actuate the push rod 41 by pressing on the head to set the clutch and start the spindle shaft.
- the clutch when set is held in this'position by the latch 43 which springs into engagement with the pin 44.
- the clutch when set connects the sleeve 28 together with the cam 32 and the gear wheel 33 with the driving shaft 25.
- the gear wheel drives the spindle shaft 51 through the pinion 52 at a relatively high speed and thereby immedi ately starts the winding operation.
- the cam 32 causes the rocker 93 to oscillate, the rocker being provided with a projection 140 which engages a cam slot 141.
- This oscillatory movement produces a reciprocatory movement of the collar 90 which carries with it the sleeve 7 3 and the feed bar 102.
- the length of this stroke determines the diameter of the cop as more fully explained hereinafter and may be determined by adjusting the support 94 toward or away from the projection 140 of the rocker.
- the reciprocatory movement is uniform but in addition to this backward and forward movement of this bar 102 there is a step by step advancement or translatory movement of the bar, each stroke being advanced a little farther thanthe last by reason of a rotative adjustment of the sleeve 7 3 which acts like a stationary nut in effecting a relative movement between the sleeve 73 and the feed bar.
- the rotative movement of the sleeve is produced at each stroke of the collar. 90 by reason of the successive engagement of the pin 91 of the collar, with the cam surface 81 of the pawl carrier 76. This engagement produces a rotative movement of the pawl carrier and causes the pawl to rotatively advance the sleeve by engaging the teeth of the ratchet flange 71.
- the sleeve 70 is keyed to the sleeve 73 and consequently the movement is transmitted to the latter which is thus subjected to two independent movements.
- the projection 48 which constitutes a stop, is adjustable on the feed bar 102 and consequently may be set to determine the length of the cop.
- the feed bar 102' is returned to its initial position as hereinbefore set forth by the action of the arm 39 upon the rod 112 whiohreleases the rack teeth from the threads of the sleeve.
- the feed bar is then pushed inwardly by the spring 170 until the stop 165 engages the adjacent end of the'sleeve 73.
- the operator therefore only has to reset the bar 112 and the-clutch which may be accomplished simultaneously by actuating the push rod 41. If the spring 170 and the link 171 are omitted the operator manually returns the feed bar to its initial position after it has been released from the teeth of the threaded sleeve by pulling on the rod 112.
- the oscillatory movement of the pawl carrier may be effected as shown in Fig. 11
- the driving shaft . is provided with an eccentric cam 160 with which an actuating lever 161 co6perates.
- This lever is pivoted at 162 and is con-- nected at its free end, by an adjustable link 165, with the pawl carrier 7 6 which is similar to the carrier 76 except that the cam projection 80 is omitted.
- the link. 165 is pivotally connected to the pawl. carrier 7 6 extends loosely throu h a hole in the lever arm 161, and has an a justing nut 164 which is held in engagement with the lever arm by a spring 163. Consequently the pawl carrier is oscillated with the lever arm 161 in response to the movement of the eccentric I,

COP-WINDING MACHINE.
Application filed April 29, 1914. Serial No. 835,060.
T 0 all whom it may concern:
Be it known that I, ALMON B. CALKINS, a citizen of the United States of America, and a resident of Nutley, Essex county, and State of New Jersey, have invented certain new and useful Improvements in Cop-Winding Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
My inventionv relates to winding machines, and particularly to such as are adapted for winding thread or yarn onto bobbins-and are known as cop-winders.
One object-of my invention is to provide a durable and reliable machine for the aforesaid purpose that shall comprisea relatively few number of simple parts and shall be'inexpensive to construct and easy to assemble. 7
Another object is to provide a cop-winder,
by which accurate and uniform cops may be closely vand automatically wound in an improved manner. M Another object is to provide a winding machine which is capable of careful adjustmentsto accommodate thread or yarn of varying sizes and to ing lengths.
Other objects and advantages of my invention will be set forth hereinafter, and in order that my invention may be thoroughly produce cops of varyunderstood, I will now proceed to describe the same in the following specification, and then point out the novel features thereof in appended claims.
Referring to the drawings: I Figure l is a partial-end elevation of a multiple spindle machine, each unit of which is complete in itself and embodies my invention.

lines 7-7, M, 9-9, and 10 -10 of Fig. 3..
A modified operative connection for the feed pawl carrier is shown in Fig. 11.
Like characters of reference are designated by corresponding parts in all the figures.
Frame.
The machine illustrated comprises a frame having spaced uprights or legs- 12' (only a part of one of which is shown), longitudiards 16 mounted'upon the plate or web 14' over the uprights or legs, and longitudinal rods or bars 18 supported in brackets 19 and 20 on the standards 16. Secured t0 the lon-' nal connecting plates or webs 13 and 14, a-
longitudinal shaft or bar 15, vertical stand- 'gitudinal shaft or bar 15 area plurality'of The standards 16 are mounted'in sockets 17 and-thebrackets 19 and 20 are adjustable on the standards and may befixed in any suitable position by set-screws as shown in Fig. 1.
CWt'ch. 1
The operating mechanism will now bedescribed as if the whole machine comprised only a single unit. Secured to the driving shaft 25 is a clutch collar 26 (see Fig. 2) havingactuating lugs 27 projecting laterally therefrom. A sleeve 28 which 1s rotatively mounted 'on the shaft has mounted upon it a clutch collar 29 with lugs 30 which are adapted to cooperate with the lugs 2?. The sleeve is'prevented from sliding longitudinally of the shaft by :the clutch collar 26 and a collar 31 at its. opposite end. The clutch. collar 29 .is splined or otherwise mounted to slide on the sleeve and to turn with it. Integral withfor secured to the sleeve are a cam 32 and a 'worm' wheel 36. A pair of springs 34 tend to automatically release the clutch by pullirigthe collar. n29 away from the collar 26 and a vertical in opposition to the springs.
Above the pin 44 is a pivot pin 45 which carries a releasing pawl 46 and a lever arm 49, and may be rocked to actuate the pawl either manually or automatically by a pull rod 47 which is connected to the arm 49, or automatically by means of an adjustable stop 48 as hereinafter explained.
Spdndle.
Each of the'bracket arms 24 has a pair of spaced bearings 50 which rotatively support a spindle shaft 51. Secured to the shaft between the bearings, and in mesh with the gear wheel 33, is a worm or pinion 52 and removably supported on the tapered outer end of the shaft, which extends through the face plate 13, is a bobbin 54. The bobbin is connected to be driven by the shaft 51 which is supported at its outer end by a bracket 55, mounted near the outer end of a stationary tube 56. The bracket is arranged to both turn and slide on the tube 56 but is limited in its movements by an L- shaped slot 57 in the tube which is engaged by a pin projection 58 of the bracket. A bayonet joint is thus formed which permits the bracket to be moved backwardly in an axial direction and then moved rotatively to permit the ready removal of the bobbin 54 after the cop has been wound, upon it. A helical spring 59 is mounted on the tube beyond the bracket and tends to hold the bracket in its operative position.
'The stationary tube 56 is substantially parallel to the axis of the shaft 51 and the bobbin 54 and is supported at its inner end by means of a socket 60 mounted on the face plate 13. The tube is provided with a longitudinal slot 61 as clearly shown in Fig. 5, and a cylindrical block 62 is mounted to slide inthe tube and carries a thread guide 63 which extends through the block and through the longitudinal slot 61 as shown in Fig. 3. An eyelet 64 is secured to the thread guide near its upper end, the lower end being enlarged at 64 and provided with a notch 65. The thread or yarn, as more fully explained hereinafter, extends downwardly through the eyelet 64 and the notch 65 onto the bobbin.
F eed mechanism.
A hollow cylindrical bracket 66 having end flanges 67 and 68 is secured to the face plate 13 on its inner surface and is in alinement with the stationary tube 56, a suitable hole 69 being provided in the face plate, so that there is a continuous opening through the cylindrical bracket and the tube. Within the hollow cylindrical bracket is rotatively mounted a sleeve 70 having a toothed flange 71 at one end and a. nut 72 at the opposite end. Within this sleeve and con nected to be rotated with it is a sleeve or nut 73 which is internally threaded at 74 and extends beyond the sleeve 70 at one end where it is provided with spaced annular projections 75.
A pawl carrier 76 is rotatively supported 'on the sleeve 70 and comprises a hub 77 which is interposed between the flange 68 of the hollow cylindrical support and the toothed flange 71 of the sleeve. A pawl 78 is pivotally mounted on the pawl carrier and is adapted to engage the toothed edge of the flange 71 against which it is pressed by a spring 79 as clearly shown in Fig. 7.
The hollow carrier has a cylindrically curved extension 80 which is beveled to provide a cam surface 81 and opposite the extension 80 is an arm 82 which engages an eccentric stop 83. This stop is in the form of a disk eccentrically mounted at the inner end of a shaft 84-which extends through the face plate 13 and has an adjusting knob 85 at its outer end. The knob has anindex flange 86dprovided with a circumferential slot 87, an
through the slotinto the face plate thereby limiting the adjustment of the eccentric. The eccentric may be set at any desired intermediate position and the flange 86, and
.the adjacent 'surface of the, face plate are graduated for the guidance of the operator. A collar 90 forms a bearing for and is mounted near one end of the sleeve 73 between the annular projections 75 and has a laterally projecting pin 91 which coiliperates as shown in Fig. 6, with the cam su ace 81 of the awl carrier extension 80. The collar 90 1s operatively connected by a link 92 and a rocker 93 with the cam 32, the rocker a stationary stop or pin 88 extends being pivotally mounted on a vertically adjustable stationary support 94 as shown in Fig. 1. This support is secured to a verticallyslotted extension 95 of'the bracket 21 and carries a pivoted. nut 96 with which a screw-threaded shank 97 of the rocker cooperates.
The collar 90 is prevented from rotating by a stationary frame which comprises a pair of spaced rods or bars 98 having overturned ends 99 which are bolted or otherwise secured to the flange 68 and are connected at their opposite ends by a plate 100. These bars-engage notched projections 101 of the collar as clearly shown in Fig. 8. f A feed bar 102 extends from the cylindrical block 62through a portion of the tube 56, the sleeve 73, and through a suitable guide opening 103 in a block 104.
The cylindrical block 62 is provided with a screw plug 105 'having a transverse dovetail slot 106 in its head. The adjacent end of the feed bar 102 is enlarged at 107 to-cooperate with the dove-tail slot 106, the plug 105 being screwed into the end of the cylindrical block 62 as shown in. Fig. 3. The
feed bar is less in width than the diameter of the cylindrical opening of the tube 56, which corresponds quite closely in size to the cylindrical opening of the quill 73, and
These blocks are simultaneously adjusted to move the bar 102 into and out of mesh with the threadedsleeve by means of a sliding rod112. This rod is mounted to slide through suitable openings in the face plate 13, the flanges 67 and 68, and the plate 100. One of its edges is straight and this edge is held in engagement with alining surfaces'of the uide openings, by means vof springs 113. The opposite edge of the rod 112 has a beveled end surface 114 whichis adapted to codperate with the block 104 and a beveled surface 115 near its opposite end which is adapted to coiiperate with the block 109. The blocks 104 and 109 are pressed downwardly by sprin wardly by means of a handle 116, the blocks follow the beveled surfaces114 and 115- and disengage the rack from. the teeth of the reverse movement of the rod 112 simultane- 104 and 109 andvtend .to move so as to disengagetherack from the threaded sleeve and; consequently when the rod 112- is moved outousl moves the blocks 104 and 109 out.-
- war ly thereby throwing the rack into mesh with the threads of sleeve 73. 1
The inward movement of the feed bar when disengaged from the threaded sleeve is limited by a stop 165 which is adapted, to engage the adjacent end of the threaded sleeve and-is secured to the feed bar near its outer end. It extends inwardly therefrom 1n parallelism with the bar for a predetermined distance, dependent upon the starting point for winding the cop. This stop does not otherwise interfere with the movement or adjustment of the feed bar as set forth herein, since it is adapted to extend below the guide block 109.
In order to makethe return movement of the feed bar and thread guide automatically dependent upon the release of the clutch, I
provide a suitable spring such as spring 17 0.
which tends to push the bar backwardly and connect the rod 112 to the arm 39 by link 171 as shown in Figs l and 4.
' Drag mechanism.
Secured to the longitudinal rod 18 which is carried by the brackets 20, is a socket 120' from which extends outwardly a spindle 121, a spool 122 of thread or cord being mounted thereon. The 001 is .freely rotatable on the'spindle An arm 124 is secured to the longitudinal rod 18 which is carriedby the brackets 19, and has a lateral shaft projection or pin 125 near its outer end. -A' sheave or pulley 126 is mounted on the shaft or pin 125 and has a-grooved periphery which is engaged by a drag roll 127. The latter is supported by a trunnion 128 on a short spindle 129 which is supported by the arm 124 and is spring-pressedinto' engagement with the periphery of the sheave 126, thereby producing a drag on the thread in a well known manner. Y
A bell crank .lever mounted on the shaft 125 and carries an eyelet 131 near the outer end of its longer arm. A spring 132 is connected to its shorter arm and holds the thread under tension.
A small bracket 133 is secured to the face plate 13 and a lever 134, to the upper end of which a guide eyelet 135 is connected by a spring136; The lever is pivoted on the bracket intermediate of its ends and the end opposite the spring is adapted to engage and actuate the overturned end of the pull rod 47 when the tension on the spring 136 is released.
Under operating conditions, as more fully explained hereinafter, the spring is kept un der tension by the thread which extends from thespool 122 ,over the drag pulley 126 through the eyelet 131, the guide eyelet 135 and the eyelet 64 which is attached to the feed mechanism and through the notch 65 paper or other suitable material and tapered slightly toward outer end in order to ut is prevented I from slipping off by a stop 123.
130 is also pivotally I facilitate the unwinding of the cop. It is inserted in the machine on the tapered end of-the spindle adjacent to the bracket 55. A spool of thread or yarn is placed on the spindle 121, the thread being passed over the drag pulley and through'the eyelets as hereinbefore set forth, its end being started on the bobbin near the larger end thereof in a well known manner. Care of course should be taken that the feed .bar is adjusted to such position that the thread guide is opposite thelarger end of the bobbin as shown in Fig. 1. v
The machine is now ready to start and it may be assumed that the driving shaft 25 is rotating. Under these conditions it is only necessary to actuate the push rod 41 by pressing on the head to set the clutch and start the spindle shaft. The clutch when set is held in this'position by the latch 43 which springs into engagement with the pin 44. The clutch when set connects the sleeve 28 together with the cam 32 and the gear wheel 33 with the driving shaft 25. The gear wheel drives the spindle shaft 51 through the pinion 52 at a relatively high speed and thereby immedi ately starts the winding operation. At the same time the cam 32 causes the rocker 93 to oscillate, the rocker being provided with a projection 140 which engages a cam slot 141.
This oscillatory movement produces a reciprocatory movement of the collar 90 which carries with it the sleeve 7 3 and the feed bar 102. The length of this stroke determines the diameter of the cop as more fully explained hereinafter and may be determined by adjusting the support 94 toward or away from the projection 140 of the rocker. The reciprocatory movement is uniform but in addition to this backward and forward movement of this bar 102 there is a step by step advancement or translatory movement of the bar, each stroke being advanced a little farther thanthe last by reason of a rotative adjustment of the sleeve 7 3 which acts like a stationary nut in effecting a relative movement between the sleeve 73 and the feed bar.
The rotative movement of the sleeve is produced at each stroke of the collar. 90 by reason of the successive engagement of the pin 91 of the collar, with the cam surface 81 of the pawl carrier 76. This engagement produces a rotative movement of the pawl carrier and causes the pawl to rotatively advance the sleeve by engaging the teeth of the ratchet flange 71. The sleeve 70 is keyed to the sleeve 73 and consequently the movement is transmitted to the latter which is thus subjected to two independent movements. j v The extent of rotative movement efiected by each stroke of the collar depends upon the setting of the eccentric 83 which determines the position to which the pawl returns durin the return stroke of the collar which is efl cted by a spring 150 (see Fig. 8). This adjustment determines the relative position of .each layer of the cop to the preceding and is set with reference to the size of the thread of yarn which is being wound. The winding process continues as indicated, as long as the thread or yarn is not broken, unless the operator releases the clutch by actuating the pull rod 47 or unless the latch 43 is released in some other way, as, for example, when the pin 48 engages the arm 49 at the end of the cop. If the thread breaks, the reactionof the spring 136 will cause the lever 134 to rock on the bracket 133 and its lower end will then release the clutch by actuating the pull rod.
The projection 48 which constitutes a stop, is adjustable on the feed bar 102 and consequently may be set to determine the length of the cop.
When the cop is completed and the machine is stopped, the operator swings the bracket 55 out of the way, removes the cop,
and puts in a new bobbin. The feed bar 102' is returned to its initial position as hereinbefore set forth by the action of the arm 39 upon the rod 112 whiohreleases the rack teeth from the threads of the sleeve. The feed bar is then pushed inwardly by the spring 170 until the stop 165 engages the adjacent end of the'sleeve 73. The operator therefore only has to reset the bar 112 and the-clutch which may be accomplished simultaneously by actuating the push rod 41. If the spring 170 and the link 171 are omitted the operator manually returns the feed bar to its initial position after it has been released from the teeth of the threaded sleeve by pulling on the rod 112.
The oscillatory movement of the pawl carrier may be effected as shown in Fig. 11
81. In thismodification'the driving shaft .is provided with an eccentric cam 160 with which an actuating lever 161 co6perates. This lever is pivoted at 162 and is con-- nected at its free end, by an adjustable link 165, with the pawl carrier 7 6 which is similar to the carrier 76 except that the cam projection 80 is omitted. The link. 165 is pivotally connected to the pawl. carrier 7 6 extends loosely throu h a hole in the lever arm 161, and has an a justing nut 164 which is held in engagement with the lever arm by a spring 163. Consequently the pawl carrier is oscillated with the lever arm 161 in response to the movement of the eccentric I,
is also arranged to be rotatively moved through a suflicient arc to permit the notched end of the thread guide to swing, asclearly indicated in broken lines in Fig. when the guide moves back and forth over the tapered it passes through the notch the eyelet 64: is
- guide and always maintains its position rela arranged to extend outwardly from the upper end of the thread guide for a considerable distance. Since it. swings with the tive to the notch, it holds the thread at a fixed angle to the guide and permits it to pass through the notch without rubbing.
