AThis invention relates to machines for the automatic winding of embroideryvthread of silk, cotton, yarn, or artificial silk,I into skeins. Heretofore,`it has been the common practice to wind the thread into skeins and to out and tie the ends of the threads about the skein windings by hand; .and while at-v tempts have been madeto devise machines for performing the winding and other opera-- tions mechanically and automatically, such machines have usually resorted to the tying of the Severed ends of the thread which form the skein, in a manner somewhat similar to the hand operation. The automatic tying machines have -not proven very successful and conseguently practically all of the skein winding one at the present`.time is performed by hand labor. The principal object of this invention is to provide a 'machine for winding the thread in skeins, cutting the end of the thread after the skein has been linshed, and Securing the two ends of the skein, the operation of the machine being entirely automatic. Other'more detailed objects of the invention will appear fromthe description hereinafter. l

The skein winding means;

D. Skein advancing means; E. Skein stapling means; F. Skein cutting and separating means, Land G. Staple wire supporting an feeding means. l A

A. F rame work and main dri/ving mechanism (Figs. 1, 2 and 3) 4 -Themain frame of the machine consists of a casting of any suitable metal, having an extended base 10, from which the standard 11 projects upwardly; said standard havingk 'I a laterally extending arm 12vv projecting over and beyond the' base 10. A motor 13, suit ably secured as'by the bolts 14 to the base 10 provides the motive power for operating 'themachine. and said motor is 'connected by means of a belt 15 with a pulley .16 forming a part oflatubular shaft 17. The tubular shaft 17 forms the outer member of a. plurality of nested, vcoiflcentrically arranged shafts, someof which are stationary 4to provide supports` solid shaft 18 and a hollow shaft 19. The

hollow shaft'19 which formsl a support for the bearings .of `the rotatable shafts, `is mounted-in a suitable bore provided in the standard 11, an-d as shown in Fig. 3, is secured against movement lwithin said bore by f an suitable means such as the bolts 20. The

so id shaft 18 is held against rotation by means ofv a strap 21, the ends of which are secured to the standard 11 by the cap screws 22, and the central part of said strap 21 1s Secured to the solid shaft 18 by the screws 23. Mounted in the annular space between the stationary hollow shaft 19 and the stationa-r shaft 18 is a rotatable hollow shaft 24; suitable-bushings 2:5 and 26 being interposed between said shafts to furnish bearlng surfaces for the shaft 24. Similar bushings 27 are interposed between the hollow stationary shaft 19 and the hollow rotatable outer shaft 171 The hollow shaft 17, adjacent to the pulley 16, is rovided with a spur pinion 28 which mes ies with a spur pinion 2'9 secured upon a shaft 30, shaft 30 passing throu h the standard 11 below the nested shafts, ereinbefore referred to, and parallel therewith. The rear end of the shaft 30 has secured thereto a. bevel gear 31 meshing with a bevel gear 32 secured to the lower end of a vertically extending shaft 33, suitably mounted for rotation in the bearings 35 and 36, said shaft extending upwardly with its longitudinal axis intersecting the continuation of the axis of the nested shafts.v

A bevelled gear 37, secured on the vertically extending shaft 33, meshes with a bevelled gear 38, the gear 38 being connected to the hollow shaft 24. The upper end of the vertically extending shaft 33 has secured thereto a miter gear 39 which meshes with a similar gear 39a secured upon the rear end of a horizontally extending cam shaft 40.

B. Slcen supporting meant` (Fz'gsL 2, 3

and 11) l whlch engages the front face of the boss 42' the rear end of each rod 43 having secured thereto a collar 45, which vcooperates with the shoulder 44 to prevent longitudinal-movement of the rods within the aperture of said boss 42. As clearly shown in Figs. 2, 3 and 11 of t-he drawings, the forward end of the rod 43 projects outwardly beyond the boss 42 and said outer projecting end is screw threaded to form a thread of large pitch, as indicated at 46. The recessed portions of the threads so formed form seats in which the threads of each skein'are seated by the skein windin mechanism to be hereinafter described, an the spider 42 and rods 43 formy in effect a skein supporting frame.

0. The .skein winding means (Figs. 2, 3, 4 and 5) Suitably secured upon the front end of the rotatable outer hollow shaft 17, to rotate therewith vis an arm 47 having a pair of laterally extending branches 48, 49 upon its router end, which form with the arm 47 a substantially T-shaped member. The branch 48 is provided with an aperture 50 through which the thread 5l from the cone or bobbin 52 passes; said bobbin being frictionally secured upon a tapered shaft 53. The shaft 5 3 is non-rotatably secured upon a'bracket 54, bolted to the hollow shaft 17 as by the bolts 55 (see Fig. 4), and said bracket is formed to provide a substantially cup-shaped member 56 which forms av guard within which the bobbin 52 is seated. A counter weight 57 is secured to the shaft 17 at a point diametrically opposite the shaft 53 for the purpose of balancing the weight of the bracket 54 and its associated parts. It will be noted from the foregoing description that the spider 41, being secured to the stationary hollow shaft 19, does not rotate, while t-he arm 47 which is secured to the hollow rotatable shaft 17 rotates about the spider 41 and its associated parts. The thread 51 which is passed through the aperture 50 of arm 48 is exten'ded forwardly under a tension spring 58 suitably secured to the arm 47, after' which the thread is passed through an aperture 59 to permit it to pass to the rods 43 in a manner which will be hereinafter more fully described. Shaft 18 is provided with a reduced extension 61 -to which a yoke 60 is secured for catching the skeins after they have been wound, stapled and severed.

D. like skein advancing means (Figs Q, 3, 4 and 11) Secured to the front end of the hollow shaft 24 is a large intermittent gear wheel or disc 62, the greater portion of the periphery of which, as shown in Fig. 5, is not provided with gear teeth. Two small sections of tbe gear wheel 62 are provid-ed at diainetrically oppositepoints with the gear teeth 63, which -are adapted to engage with the small intermittent gear pinions 64, secured to the skein supporting rods 43. The gear pinions 64 are provided on the major part of their peripheries with gear teeth, as shown in Fig. 5, the gear teeth being omitted on the remaining portion thereof to engage with the smooth portion of the periphery of the gear wheel 62 in accordance with the usual construction of devices of this character; thereby to hold the rods 43 against rotation when the uncut portions of the cooperating gears 62 and 64 are in engagement.

.That section of the large intermittent gear wheel 62 which contains the gear teeth 63 is preferablymade of a separate piece of material 65 which is dovetailed into the disc 62.

The machine illustrated is designed to form a skein of four windingsand as the gear teeth 63 are operative after each half rotation of thedisc 62, the driving means for the hollow shaft 17, the hollow shaft. 24, and the ian cam shaft 40, which shafts rotate the arm 47 and the disc 62 respectively, are so pro ortioned as to secure a speed of rotation o the arin 47 eight times as fast as the rotation of the disc 62 and four times as fast as the cam shaft the speed of rotation of the parts of the machine in the exampleshown being 480 revolutions a minute for the arm 47 to 60 and 120 revolutions a minute for the disc 62 and cam shaft 40 respectively. 1t will thus be seen that for each half revolution of the disc 62, four revolutions of the arm 47 will occur and [four loops of the thread will be laid within the innermost recesses or seats formed by the screw threads 46 for the reception of the threads. After therequired number of loops of thread have been wound about the arms 43, the cooperating toothed portions of the gears 6'4 and 63 will come into engagement, thereby rotating the rods 43 in a direction to advance the skein of thread forwardly thereof.

E. Slcez'n staplz'ng 'means (Figs. 6, 7., 9 to 18 rn/elimine) Bolted to the front end of the laterally extending frame arm 12 is a bracket or head 66, which head is provided' with suitable guides for sup orting and guiding the operating parts of t e skein stapling devices.` As shown more clearly in Fig. 9 the head 66 is provided with a bearing 67 in which the front end of the horizontally extending cam shaft 40, hereipbefore referred to,rotates. `The rear.

portion of the head 66, as shown in Figs. 7 and 9, is provided with a pair of vertically extending guideways 68 in which a` slide 694 reciprocates; said slide being retained within the guides 68 by a pair of plates 70 suitably secured, as by the screws 71, to the rear face vof the head 66'. The head 66 is also provided with a recess 72 intermediatev the guideways 68 to provide a pocket for the reception of K a spring73. The lower end of the spring 73 is supported by a plate 74, suitably securedto the bottom of the head 66 and the upper end of said spring bears against a knee bracket 75 suitably secured to the slide 69, thereby normally urging said slide upwardly as will be readily understood. l A roller 76 is secured to the rear face of the slide 69, as by the headed screw 77, Said roller being held in engagement, by the action of spring 73, with the peripheral face of'a cam 78, secured,

as by the pin 79, to the cam shaft 40. The

`1 die 80 is ixedly clamped Within the lower portion of the slide 69 by means of the plate 82, (Figs. 7 and 9)-, secured to the outer face of the slide 69 by thescrews 83. Slidably mounted for reciprocation within the groove 469a of the slide 69 is secured a second slide the second slide 84 normally in an upper i position, in contact with a bar 112. A cam roller 89, which is secured to the outer face of the second slide 84, as by the headed screw 90, is adapted .to lbe engaged by a cam 91 secured to the shaft 40, as by the pin 91a; the cams being constructed and arranged so as to cause a relative movementV of the plunger 81 with respect to the die 80, at predeter mined time intervals in a manner which will be hereinafter more fully described.

The lower end ofthe head 66 is slotted out to provide a guideway for an anvil 92 which is slidably mounted within said guideway and is retained in position therein by means Vof the plate 93. The outer end of the anvil 92 has secured thereto an upwardly projecting pin 94 (Figs. 9 and 12 to 16 inclusive), about which pin the stapling wire 95 is bent by the die to form a yoke shaped staple 96 (Fig. 16). The rear end of the anvil 92 is machined at an angle to provide a cam face 97 with which a cooperating angular cam face, provided on the lower end of a flat rod 98, is` adapted to engage. The rod 98 is s lidably mounted for vertical reciprocation within a guideway formed in the front face of the head 66, said rod 98 being retained within said guideway by the plate 99, secured as by the screws 100 to the head 66. The upper end of the rod 98 has secured thereto, as by the bolt 101, a cam roller 102, with the peripheral face of which, a cam 103 engages; the cam 103 being secured to the outer projecting end of the shaft 40 by means of the pin 104. A pair ofk springs 105, having their upper and lower ends respectively anchored to the transverse pin 106 and the studs 107, secured inthe head 66 and rod 98 respectively, normally hold the rod 98 in its upper position with the face of the cam roller 102 in engagement with the peripheral face of the cam 103. The cams 103, 91, and 78,` are so constructed and arranged that the inclined cam face of the rod-98 will engage with the inclined cam face 97 of the anvil 92, shortly before the slide 69 starts to descend. A s ring 108 (see Fig. 6) having its front end anc oredas at .108ay and its rear end anchored to the seated in recesses Iii) a supporting surface for the connecting g thread 127 between two adjacent skeins of thread as will be clearly seen in Fig. 11.

G. Staple wir@ supporting amd feeding'means (Figs. 1, 5, 6, 8 and .9)

Bolted to the planed face 130 of the bracket 66, is a reel supporting arm 131 having at the lower end thereof a boss 132. A pin 133, secured within said boss, serves as a supporting means. for a circulardisc 134, the outer face of the disc 134 bein'gprovided with an annular projecting flange or shoulder 135 about which the supply-of staplin wire 95 is coiled. A retaining plate 136,%iaving a' central circular portion with a plurality of arms 137 radiatin therefrom, is secured as by means of the nurled nut 138 upon the pin 133; the arms 137 being adapted to be 139 provided in the annular flange 135, and the construction and arrangement of the disc 134 and arms 137 being such as to hold the stapling wire '95 in properlyy coiled position upon'the reel formed by these parts. rIhe wire 95 is led from the reel to an inclined guide 140, secured within the lower slotted end of the head 66 (see Fig. 9) which serves to direct the wire 95 between a pair of feed rollers 141 and 142. The upper feed roller 141 is secured upon a-,shaft 143 whichl passes transversely across vthe lower end of the head 66 (see Fig. 8). The shaft 143 is rotatably mounted'within a suitable bore provided in the head 66 and rotates about a Xed axis. The lower roller142 is rotatably mounted in a pair of slidable bearings 145 mounted within suitable vertical slots provided in the lower end of the head 66. lhe lower end of the bearings 145 are bored out at -146 to provide a 'seat for the springs 147,

I which are coiled about the rods 148, and

the plate 93v forms a support for thel outer ends of the springs 147 thereby causin said springs to hold the roller 141 norma ly in engagement with the roller 142. The rods 148 project th'rough suitable apertures pro'k vided in the plate 93, and are connected at their outer ends by a plate 149, for a purpose which will hereinafter appear.- Gears 150, 151 are provided for driving the rollers 141 and 142 in unison andthe following means are provided for actuating the rollers 141 and 142 intermittently. A ratchet gear 152 is vsecured upon the outer end of the shaft 143 and a mutilated gear 155 is rotatably mounted on said Ashaft adjacent to said ratchet gear. A spring pressed pawl 153 is pivotally mounted upon a pin 154 projecting outwardly from the face of the mutilated gear 155 and is adapted to engage with the ratchet gear 152 and move it in a counterclockwise direction (Fig. 6). A rack 156, secured to pins 107, 157 f extending transversely through the reciprocating rod 98, is provided with gear teeth which mesh with the teeth of the mutilated ear 155 and serve to impart the proper rotation to the feed rolls 141, 142.

For convenience in threading the stapling i wire 95through the machine, means are provided for moving the roller 142 out of engagement with roller 141 and such means comprises a small hand lever 160, fulcrumed to a bracket 161 which is secured to the plate 93. The lever 160 projects forwardly between the rods 148 and its lower face engages with the connecting bar 149, so that when the lever 160 is moved downwardly, it will press `against the bar 149 and cause the rods 148 to pull the bearings 145, and shaft 144 downwardly and thereby move the peripheral face of the roller 142 out of engagement with the face of the roller 141. After the stapling wire 95 passes between the rollers 141,- itpasses through a second guide 165,. the guide 165 being suitably secured, as by the pins 166, within the lower slotted end of the head 66. j

The operation of the stapling wire supporting and feeding means is as follows: t e retaining plate 136 may be removed readily by unscrewing the knurled nut 138 thereby permitting a coil of stapling wire to be placed upon the annular flange 135, after which the retainingplate is placed back u on the pin 133 and secured in place b the nurled nut 138; the annular flange geing of slightly greater thickness than the stapling wire to prevent anyclamping of the Wire coil b retaining plate. The wire is preferabvy in the the form of a thin flat ribbon of soft brass.-

The end of the wire is threaded through the guide 140, between the feed rollers 141 and 142 andthen through the guide 165, the end of the wire being brought into alignment with the outer end of said guide 165.

When the rod 98 is moved downwardly by cam 103 to cause the anvil 92 to be moved outwardly, the rack 156 connected to said rod will rotate the mutilated gear 155 in a counterclockwise direction (Fig. 6) thus causing the awl 153 to rotate the ratchet ar 152 and s aft 143 in the same direction. his will cause the feed rollers 141 and 142 to feed a lengt-h of the wire outwardly of the guide 165 just sufficient for the making of a staple* Q 12e/ration The operation of the machine. is as follows, assuming that the stapling wire has been placed upon the reel and properly threaded through the feed rollers and guides in the manner just described: A hobbin or cone of the thread t0 be skeined is placed upon the tapered shaft 53 and the end of the thread 51 is passed through the aperture 50 of the arm 48, under the tension spring 58 and through the aperture 59 of the rod 49. The operator makes one turn of the thread about the skein supporting rods 43 and holds the free end of the thread in her hand while she starts the machine in operation. The rotation of the motor 13 will 0bviously cause the outer hollow shaft 17 to4 be rotated rapidly, and as the arm 47 is secured to the hollow shaft 17, it will rotate about the disc 62. As has heretofore been pointed out the skein supporting rods 43 are stationary, and as the aperture 59 :is in alignment with the inner seats formed by the threads 46 of the skein supporting rods, the thread will' be formed in a plurality of winds or turns about the skein supporting rods. The inachine illustrated in the drawings is designed to produce four turns of thread to a skein and during four complete revolutions of the arm 47 the machine performs a complete cycle-of itsA movements. The position of the parts indicated in Fig. 5 indicates what might be termed the finishing position of the machine, and while the arm 47 has been performing its four revolutions, the other parts of the machine have been moving more slowly through their sequence of operations. During the first four revolutions of the arm 47 .the uncut portions of the mutilated gears 62 and 64 are in engagement and the skein supporting rods l43 are held against rotation. Just as the fourth revolution of the arm 47 is completed, the teeth 63 of the gear 62 come to their operative position and cause the rods 43 to be rotated a complete revolution, thereby advancing the skein which has just been wound forwardly of the rods 43. During the first two revolutions of the arm 47, the throw 78a of the cam 78 comes into operation and causes the die 8O to be moved downwardly, the cam 103 as hereinbefore described causing the rod 98 to move downwardly and thereby move the anvil 92 out into ,the path of the die 80. The formation of the staple 96 by the d ie 8() and associated parts has been previously described. During the next two revolutions of the arm 47 the stapling operation is completed, and as shown in Fig. 11 of the drawing, the stapling operation is completed upon the skein next to the inner skein, as the arm 47 is winding the first turns ofthe next skein. Immediately before the stapling operation is completed, the cutting knife 119 which as heretofore described is connected with the slide 69, reaches its operative position, and as shown in Fig. 11, the cutting knife passes between the two outermost skeins to sever the connecting thread 127. The stapling and cutting operations are completed practically simultaneously and immediately before the , intermittent gears 63, 64, begin to operate.

longitudinally by their engagement with the.

periphery of said rods 43. Therefore the skeins are shifted sideways of the machine so that the staple which is placed upon each .skein at the centre of the machine (see Fig. l1) is located to the left of the centre upon the outermost skein and the cutting mechanism is also located towards the left of the stapling mechanism. rl`his sideways shifting of the skeins tends to keep the connecting thread 127 taut for the cutting operation.

While l have described the machine as one in which a skein of four turns or windings is made, it will be understood that any number of turns or windings might beused, by merely changing the gear ratios. Likewise the stapling wire could obviously be of any cross-sectional configuration, or of any suitable material.

It will be obvious that many changes, variations and modifications may be resorted to without departing from the spirit of my invention or the principles of construction described and illustrated herein. For example, it will be obvious that many changes in the construction and arrangement of the stapling wire supporting means may be resorted to or that any suitable stapling mechanism may be employed. Likewise any equivalent cutting or driving means may be substituted. Various changes may also be made in the thread windin device or the skein supporting and advancing means herein illustrated.
