YARN-RECLAIMING MACHINE.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed September 4, 1917. Serial No. 189,548.

To all whom it may concern Be it known that I, HARRY E. FIsH, a citi Zen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Yarn-Reclaiming Machines, of which the following is a specification, reference being had to the accompanying drawings.

It is often desirable in a garment manufactory to unravel a knitted garment or piece of fabric because of imperfections in the work, or otherwise, and reuse the yarn or threads thereof for another piece of work. Such articles are frequently formed. of two threads that in the unraveling are removed together and for economic and other reasons it is of great advantage to have such two threads separated and separately wound for future use, this being particularly true when such two threads are of different material and of different values, as for example wool and mercerized cotton which frequently are combined in a knitted garment or other article. 7

It is the leading object of my invention to provide a machine that will take two such threads as they are unraveled from the garment or piece of fabric and wind them separately, and simultaneously and evenly upon spools so that the threads can be taken to a knitting machine and again used in the customary manner. Further objects of the invention are to provide automatic means for imparting a differential speed to the two spools upon which the threads are wound so that the pull upon the two threads will be substantially uniform notwithstanding that one spool may have a greater quantityof thread or heavier thread wound upon it than the other spool; to provide means for auto matically stopping the machine when either of the spools hasv had the required amount of thread wound upon it; to provide means for so stopping the machine in the event that either or both of the threads break during the winding operation; to provide improved means for removably securing in place the rotatable spools, and also adjusting the frictional braking thereof so that one spool may slacken speed under certain conditions; and to improve generally machines for reclaiming yarns or threads from manufactured fabrics. I attain these objects by the mechanism and combination of parts illustrated in the drawings accompanying and forming a part of this specification. That which I believe to be new will be set forth in the claims.

In the drawings:

Fig. 11 is a sectional detail illustrating the connection between the reciprocating bar that carries thread-guides and the lever that reciprocates said bar.

Referring to the several figures of the drawings in which corresponding parts are indicated like reference characters:

15 indicates the base of the machine from which rise suitable frame members that constitute the supports for the various operating parts of the mechanism. Adjacent to the rear edge of the base are shown three of such supporting members indicated respectively by 16-17-48, and at the upper ends of these members is journaled a shaft 19. On this shaft. is loosely mounted a pulley 20, said pulley being movable longitudinally of the shaft by means of a bent shifting lever 21 pivoted at 9.2 to the stand ard 16,-the upper end of such lever being forked and engaging a grooved hub 23 which is formed with or made fast to the pulley 22. The face of the pulley 20 opposite the grooved hub is provided with an annular series of friction studs 24 adapted to frictionally engage the face of another pulley :25 that is fast upon said shaft 19, the two pulleys thus constituting a clutch. 26 indicates a cone pulley fast on the shaft 19, and 27 indicates a similar cone pulley made fast on a countershaft 28 journaled in bearings in the standards l7l8, this second pulley lying directly below the firstnamed. pulley. At their smaller ends they are provided with grooved pulleys 2930 respectively over which runs an endless belt 31 so that the two pulleys are always driven at the same speed. Adjacent to the front edge of the base 15 rise two frame pieces or standards 3233 respectively which are provided near their upper ends with suitable bearings in which is mounted a shaft 34 upon which is fixedly secured a cone. pulley 35. Also mounted in bearings carried by these standards 3233 and directly below the bearings for the shaft 3-1 is another shaft indicated by 36. Upon this shaft 36 is secured a cone pulley 37 which lies directly beneath the cone pulley 35. The cone pulleys 35 and 37 are slightly smaller than the rear cone pulleys 26 and 27, but are arranged respectively in substantially the same horizontal planes as those last named pulleys, but it will be noted that they are reversely arranged from the arrangement of the rear pulleys,that is the larger end of each cone pulley 3537 is toward a different side of the machine than are the larger ends of the rear cone pulleys. 38 indicates an endless belt connecting the rear cone pulley 26 and the front cone pulley 35, and 39 indicates an endless belt that in like manner connects the rear cone pulley 27 and the front cone pulley 37. It will, therefore, be evident that all four cone pulleys must be driven when the shaft 19 is driven by reason of the engagement of the pulley members 20 and 25. 40 i1 indicate two spools adapted to be rotated for the purpose of having threads wound upon them. The spools are in axial alinement with the shafts 34 and 36 respectively and are rotated as hereinafter described through such shafts. Each spool is constructed and arranged as shown in the sectional view, Fig. 5, wherein it will be seen that the inner end of the spool L0 is recessed to receive the reduced end of its bearing shaft 34-. Such reduced end of the shaft has secured upon it an annular head 42 which carries a friction band 43 of any suitable material against which the end of the spool bears. The outer end of the spool is rotatably mounted upon a short stud 44 which has an annular plate 45 at a short distance from its end to'limit the degree which the stud may enter the spool. The stud is seated in a chambered head 46 that is located in a sleeve 47 passing through the upper end of an upright standard 53. The stud -14: is retained in place in any suitable manner, as for example by a screw that may be passed through such head and project into a small annular channel l8. as indicates a ball bearing interposed between the end of the stud 44 and the end of the chamber in the head 46. 50 indicates a screw plug inserted in the outer end of the sleeve 47, and through this screw plug extends a long rod 51 that is formed with or connected to the chambered head 46. 53 indicates a light coiled spring around the rod 51 and bearing at its ends against. the chambered head 46 and the screw plug 50. It will be evident that by varying the extent to which the screw plug is inserted in the sleeve 4-7, the endwise pressure on the spool may be "aried as required for proper winding results.

The thread-winding guiding devices by which the threads are directed to the respective spools 40t1 and moved from end to end of such spools so that the winding will be performed properly embrace the following instrumentalities: The pulley 25, through the endless belt 5%, drives a pulley 55 that is fast on a shaft 56 in alinementv with the shaft 36. Such shaft is supported at its inner end in a bearing that is a continuation of the bearing of said shaft 36 and at its outer end is supported in bearings formed with the framework of a housing 57 that incloses a worm 58 fast on said shaft. This worm (see Fig. 9) engages a worm gear 59 fast on a. shaft, 60 that is journaled in bearings formed with the housing of such worm gear. Such housing is indicattd by 61, and may well. be formed with the housing member 57 that incloses the worm. On the shaft 60 is fixedly secured a pinion 62 that is in mesh with a gear 63 journaled upon a short shaft 64-. Upon the end of this shaft 64 that projects from the housing 61 is aflixcd a cam 65. 66 indicates an open frame, the side arms of which embrace the cam, as shown in Fig. 1, and fit over the shaft on which said cam is mounted. In the forward. end of this frame is journaled a roller 66 against which the perimeter of the cam is in constant engagement. 67 indicates a connecting rod extending from the frame 66 toward the center of the machine where it is adjustably connected, in a manner about to be des' ribed, to an upright lever 68 that is pivoted at 69 to a portion of the supporting framework of the machine. 70 i dicates av reciprocating bar adjustably onncctd to the le er 68 near the upper end of such lever. -This bar is slidingly supported it: two

fixed guides 71. One end of this bar 70, it will be noted, comes opposite the space between the two spools 10-41 and at that end it supports a short vertical rod 72 in the ends of which are eyes arranged to receive respectively the two threads that are to be wound upon the spools. 74 indicates a strong coiled spring secured at one end to the framework and at its other end to the lower end of the upright lever 68. Such spring tends, of course, to force the connect ing rod 67 toward the cam 65, and thus in sures a firm contact between the perimeter of said cam and the roller 66 It is important, of course, to have the reciprocation of the bar 70 of just sufficient extent to insure the guide eyes 73 being carried from end to end of the two spools so as to cause the winding of the thread over the entire length of the spools, but as such spools may vary in length, it is necessary to provide means for lengthening or shortening the effective movement of the upright lever 68 that carries the reciprocating bar. This I accomplish by providing such lever just above its pivot 69 with a slot 75 and pass- 'ing therethrough. a bolt 76, upon a projecting and enlarged end of which the connecting rod 67 is journaled (see Fig. 10). This connecting rod fits between the head of the bolt and a washer 77 that is fitted upon the reduced part of the bolt and lies against the face of the lever 68. On the opposite end of the bolt is screwed a nut 78 between which nut and the face of the lever is interposed a washer 79. From this it will be seen that the nut can be tightened up so as to hold the bolt in any adjusted position in the slot 75 without bringing to bear any pressure upon the connecting rod 67 that would prevent the free turning of such rod on the bolt. It is, of course, evident that according to the position to which the bolt is adjusted in the slot will depend the de gree of movement of the lever 68 on 1ts pivot, and consequently will regulate the reciprocating movement of the threadsguiding rod 72. The upper end portion of the lever 68 is also slotted as at 80, and through such slot passes a stud 81, the head of which bridges the slot 80 and bears against the face of the lever 68. This stud at its rear end carries a block 82 through which passes the reciprocating bar 70, said bar being locked to the block by a set screw 83. The block is preferably channeled so that its side ledges lie along the side of the edgesof the lever 68 as shown. By loosening the set screw 83 the bar 72 can be adv justed so as to bring its outer end that carries the threads-guiding rod exactly in the right relation with respect to the spools that are to be employed. and when such. correct position is attained, the bar 70 will be locked on its block by the set screw 83.

The provision of the slot 80 allows the required up and down movement of the pivot 81 relative to the lever as such lever 68 is rocked on its pivot 69. I

In rear of each spool is a roller that constantly bears against the thread that is being wound upon the spool, and as the thread winds up in increasing layers, such roller moves back and during such movement performs two functions,-namely it automatically moves the driving belt lengthwise of the front and rear pairs of cOne pulleys so as to ve gradually slow down the speed of the spoo and thereby insure a steady and even pull on the thread being wound there on; such receding motion of the roller also sets in motion the means by which the machine is brought to a stop when the particular spool that such roller is working in conjunction with is fully wound. The roller used in connection with the uppermost spool-that is the spool 40-is indicated by 84. It is j ournaled in a yoke 85 that is pivoted at 86 to an arm 87 that is pivoted at 88 to one side of a bracket 89 bolted to the framework. This arm 87 has a rearward extension 90'. This portion 90, as shown, is

depressed so as to lie slightly below the plane occupied by the main portion of the curved arm 87, and the upper face of such portion 90 is beveled or inclined to form a cam surface 91. On this cam surface 91 rests the free end of a short lever 92 which lever is pivoted at 93 to a fixed portion of the framework. Midway between the ends of the short lever 92 is pivotally attached :1 depending bar 94: that passes through a guiding member 95 attached to the framework, and at its lower end comes opposite a ledge 96 that is formed with and projects up-.

wardly from an arm 97. This arm 97 has a hub portion 98 that is journaled on a vertical pin 99. 100 indicates a coiled spring around and secured to said pin 99 and also secured to the hub 98 and acting to swing the arm 97 when permitted to do so by the raising of the bar 94 sufliciently to clear the ledge 96. The arm 97 is connected by a link 101 to a crank 102 fast on a rock-shaft 103 that extends alongat one side of the machine and near the base thereof. This rock-shaft 103 is suitably journaled in short standards, one of which is shown and indicated by 104, and near the upper end of such short standards is journaled another rock-shaft 105. The two rock- shafts 103 and 105 are normally connected together through the instrumentality of a hand lever 106 that is made fast to the forward end of the shaft 105 and has a latching engagement, as best shown in Fig. 8, with an arm 107 fixedly secured upon the forward end of said shaft 103. The latching connection of the hand lever 106 with this arm 107 is efl'ected by means of a pin 108 engaging a notch in one end of the arm 107. Such engagement is intentionally of a character that can be broken with comparatively little difiiculty when required, but which will be firm enough to hold the parts in normal position. The turning of the rock-shaft 103 by the swinging of the short lever 97 in the manner described will, of course, rock the arm 107 so as to break the latching engagement referred to, and thereupon the other rock-shaft will also be rocked and such rocking or turning will be compelled by the endwise pressure of a longitudinally-movable rod 109. This rod 109 has at its outer end, as best seen in Fig. 2, a fiat head 110 with which a small roller 111 contacts, such roller being journaled in the end of a crank 112 fast on said rockshaft 105, and as this crank 112 stands at a little upward inclination any endwise movement of the rod 109 will throw the outer end of said crank upward and cause a turning of the rock-shaft 105 with which it is connected. Such turning may also be assisted by a coiled spring 113 (see Fig. 7) encircling the rock-shaft and connected to it and also to the short standard 104. but ordinarily, it is believed, the turning of the shaft 105 can be accomplished without the use of such spring. The endwise movement of the rod 109 is effected by means of a coiled spring 114 that is interposed between a collar 115 that is fast on said'rod and the lower end of the bent shifting lever 21 that has a suitable connection at its lower end with the rod 109,.such connection being preferably a pin and-slot connection as illustrated. The effect of such endwise moving of the rod 109 is to turn the shifting lever 21 upon its pivot 22, and thereby, of course, draw the driving pulley 20 out of frictional clutching engagement with the pulley 25, and that necessarily stops the machine. It will be noticed by reference to Fig. 2 that the driving belt indicated by 116, that leads from any suitable motor over the pulley 20, is conducted to that pulley 20 on a slight incline, and such inclination would aid in the shifting of the pulley 20 as the drive belt would necessarily tend to run in a straight line.

From what has been said, it will be evident that as the layers of thread multiply on the spool 40, the roller 84 will gradually be pushed back and cause a turning of the curved arm with which it is pivotally connected, and as this movement takes place the short lever 92 will very gradually be lifted .by riding up the inclined or cam surface 91;

upon the required amount of yarn or thread being wound upon such spool to fill it, the

lever 92 will have been raised to the highest point of the cam surface, which will draw up the bar 9% sufficiently to disengage it from the ledge 96, whereupon the movement of the other parts that operate to stop the machine will occur as described. Behind the lower spool is lo"a'ted a duplicate set of devices such as described in connection with the upper spool, and they are, therefore, correspondingly numbered. The short pivoted lever 92 of this lower set of devices is also pivotally attached to the vertically sliding bar 9%, and therefore, it is evident that through that lower one of the two lovers 92 said bar may be moved upwardly to exactly the same extent and for the same purpose as in the case of the upper pivoted lever 92.

Now it is evident that if both spools -l-0-l1 have threads wound upon them simultaneously to the same extent and both threads are of a character to increase the diameter of the spools equally. then the two sets of mechanism will move exactly alike and each of the levers will exert an equal lifting effect upon the bar 9% and both spools will be completely wound when the. machine is automatically stopped in the manner described. But it may well happen that owing to the different character of threads being wound upon the two spools or be-auee the. machine may be started with one spool partially filled and the other empty. that the two sets of mechanism will not, of course, move exactly the same. F or example, we will suppose that when the machine is started that the upper spool -10 has a considerable quantity of thread wound upon it, whereas the lower spool i1 is empty. The result will be, of course, that the winding of the upper spool will be finished by the time that the lower spool is only partially wound. It is just as necessary, of course. that the machine be automatically stopped when one of the spools is completely wound as in the case where the winding is finished on both spools at the same time. In the case supposed, the devices controlled by the barkward movement of the roller S-l that contacts with the upper spool will at all times be advanced farther in their moven'ients than the corresponding devices of the lower set, and the lifting will all be done through the medium of the upper pivoted lever owing to the fact that the lower lever 92 will be held out of contact with its cam face 91. It will thus be seen that the two mechanisms may unitedly lift the bar 94 out of holding engagement with the spring-pressed pivoted. lever 97 or either one of them may perform that operation, depending upon the quantity of thread on the spools.

It is highly desirable that an even and regular pull be exerted on the threads as they are drawn to and upon the respective spools 4l0-41, and with the machine being driven at a uniform rate of speed during the winding operation this would not be possible unless some provision were made for so drawing the threads, because of the fact that as the layers of thread multiply on the spools, the surface speed of the thread on the spools increases. To attain the desired even pull I have provided in connection with each of the mechanisms controlled by the gradual backward movement of the rollers 84 certain means for automatically efi'ecting a lateral shifting of the belts 38 that extend between the two sets of rear and front cone pulleys, and as these devices are exactly the same in connection with each set of mechanism they are marked with the same reference numerals. As best shown in Fig. 1, it will be seen that to that end of the bracket 89 opposite the point of attachment of the curved arm 87-90 is pivoted at 117 an arm 118 which carries at its rear free end an upright roller119. 120 indicates a link pivotally connected at 121 to the arm 118 and pivoted at 122 to the short arm of the curved member 8790. The upright roller 119 lies in contact with the edge of the ad jacent drive belt and as the spool roller 84 and its attached curved arm moves slowly back, such curved arm, turning on its pivot 88, will cause the upright roller 119 to move such belt along its cone pulleys-moving it toward the smaller end of the rear cone and the larger end of the front cone, and hence regulating the speed of the shaft carrying the spool so as to maintain the desired even pull on the thread being wound thereon. A corresponding belt shifting device is pro .vided in connection with the mechanism in rear of the other spool whereby in like manner the position of the other belt on the two Other cones is regulated. Each belt shifting mechanism is entirely independent of the other, as is the case with the machine stopping mechanisms with which they are respectively connected.

In addition to providing means for automatically stopping the operation of the ma chine when one or both of the spools is or are fully wound, it is of very considerable importance to have the machine automatically stopped in the event of the breaking of either or both ofthe threads that are being led to the spools. I have provided means for the accomplishment of this object which I will now describe. At the front of the machine rise two frame members or standards 123-12 1. These members carry two sets of cooperating thread engaging devices, one set for use in connection with the thread led to the spool 40 and the other in connection with the thread led to the spool 11. The construction and operation of each set of devices is exactly the same, and therefore, they are indicated by the same numerals and a description of the construction and operation of one set will suffice for the other. 125 indicates a plurality of wires extending horizontally from the inner face of the up right 123. The end wires of this set are coiled upon themselves to provlde guide loops 126 the intermediate wires being over the spaces between the set of wires 125. 7

These wires 127 are carried by a head 128,

such head being integral with an arm 129 that fixedly secured to a short shaft 130 journaled in a bearing that is formed with a bracket 131 projecting from the inner face of the upright 12 1'. On the opposite end of said short shaft is fixedly secured a bellcrank lever 132 and to the outwardly-extending member of this bell-crank lever is attached one end of a light coiled spring 133, the other end of which is attached to a ten sion regulating screw 131 that passes through a bracket 135 on the upright 124. The other end of this bell-crank lever has pivotally attached to it the upper end of a link 136.

This link passes through an opening in a guide bracket 137, and the lower end of such link is immediately over and in close proximity to the long end of the arm 107 that is fast on the rock shaft 103. In operation the thread to be wound upon one of the spools will be passed between the two sets of wires 125 127, and through the loops 126 on the end wires 125, from which it will pass through the proper eye 73 of the rod 72 and thence to the proper spool. The taut thread in its passage between the wires will exert a suificient upward pressure on the set of wires 127 to keep those wires in a substantially horizontal position, this upward pressure being. as will be understood, against the action of the light coiled spring 133. The loops 126 on the lower set of wires hold the thread from rising and unduly raisin; the set of wires 127. If the running thread should break, the upward movement on the set of wires 127 would, of course. be released, as soon as the end of the thread passed beyond the wire fingers, and immediately thereafter the coiled spring 133 would turnthe bellcrank lever 132 to which it was attached, which in turn would cause a rocking of the shaft 130 and a swinging down-of the arm 129 that is also fast on the short shaft 130, the wires 127 passing down between the wires 125. The swinging of the bell-crank lever 132 would also force down the depending rod 136- connected therewith and cause it to strike the end of the arm 107 with sufficient force to release the pin 108 from its engagement with the hand. lever 106. The rock-shaft 105 would thereupon be turned and the machine stopped through the movement of the parts 109, 21 and 20 as described in connection with the stopping operation caused by the completion of the winding of the spool. As before explained there is a set of devices of the character just described employed in connection with each of the two threads-the only difference between the two sets being that, necessarily, the rod 136 carried by the lower bell-crank lever is shorter than the rod carried by the other bell-crank lever. It, therefore, follows that upon the breaking of either thread the machine will immediately be stopped in the manner described.

Many changes in details of construction from that shown and described may be made Without departing from the spirit of my invention, and except as specifically claimed my claims are not to be construed as limited to such details.

I11 a machine of the class described, the combination with two thread-receiving spools arranged in different horizontal planes and means for rotating them simultaneously, of mechanism for stopping the machine comprising two duplicate and independently acting sets of members each set being arranged in operative relation to one of the spools and in contact with the thread being wound upon that spool and also comprising a third set of elements arranged at a distance from said two independentlyacting sets, and a depending bar connected with a pivoted member of each of said independently-acting sets and in movable locking engagement with the said third set.

10. In a machine of the class described, the combination with two thread-receiving spools arranged in different horizontal planes, and means for rotating them simultaneously, of mechanism for stopping the machine comprising two duplicate and independently acting sets of members each set being arranged in operative relation to one of the spools and in contact with the thread being wound upon that spool and also comprising a third set of elements arranged at a distance from said two independently-acting sets, and a depending bar in movable locking engagement with said third set and adapted to be raised by the simultaneous action or the separate action of said two in dependently-acting sets.

11. In a thread-winding machine, the combination with a driveshaft and a clutch device thereon, of a second shaft, a cone pulley fast on each shaft, an endless belt passing around said pulleys, a thread-receiving spool rotated by said second shaft, a device for gradually moving said belt along the pulleys as the winding operation progresses, means for automatically shifting one of the clutch members on the drive-shaft for the purpose of stop-ping the machine, and a movable device in constant engagement with the thread on the spool for simultaneously moving said belt-shifting device and said clutch-shifting means.

12. In a machine of the class described, the combination with two thread-receiving spools and means for rotating them simultaneously, of means for gradually varying the speed of the spools independently as successive layers of thread are wound thereon, and means for stopping the rotation of both spools when the winding on either spool is completed.
