UNITED STATES WILLIAM VORDERWINKLER, OF ROSE'LLE, NEW JERSEY.

VTINIDING AND REELING DEVICE.

Original application filed May 11, 1922, Serial No. 560,025. Divided and this application filed March T 0 all whom it may concern:

Be it known that I, VVILmAM Vononn- WINKLER, a citizen of Austria, residing at Roselle, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Winding and Reeling Devices, of which the following is a specification.

The principal object of this invention is to provide a new and improved device such shown in my copending application, Serial No. 560025, filed May 11th, 1922, of which this application is a division, for winding yarn, thread, etc, upon cone bobbins such as are commonly'used for knitting machines, which device is simple in construction, composed of few parts, can be manufactured and sold at a low price and will not necessitate a high maintenance 'eX- pense.

3 Another object is to provide a novel means for reciprocating the yarn or thread guiding means, and

Another object is to so construct the ma chine that the bobbin being wound will rest upon a stationary shaft and be rotated thereon by the frictional contact of a rotating driving member: with its periphery.

For the accomplishment of these and such further objects as will hereinafter be ap parent to those skilled in the art to which this appertains, the invention consists in the construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawings, wherein is shown a prefered embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the claims hereunto appended.

In the drawings forming a portion of this disclosure- Fig. 1 is a side elevation of a preferred embodiment of my invention.

Fig. 2 is adetail showing a front view of the driving means for the reciprocating thread guide.

i Fig. 3 is a section on the line 3-3 of Fig. 2.

As shown in the drawings, a frame comprised of the uprights 10, and 11, lower braces 12, top pieces 13 and front bar 14, is provided. Mounted in journals 15 carried by the lower braces 12, is a main driving shaft 16, upon which is pivotally mount- Serial No. 622,465.

ed a swinging frame 17, provided at its upper end with a pair of spaced journals 18 in which is rotatably received a short shaft 19. Fixedly secured to the shaft 19 1s a driving cone 20, a sheave pulley 21 being secured to the shaft 19 adjacent the upper bearing 18. A laterally projecting lug 22 integral with the frame is drilled to receive securely the headed stub shafts23 upon which are rotatably mounted the idler sheaves 24 over which and the sheave 21 is trained the belt 25, which passes over a drit ing sheave 26, secured upon the main shaft 16. A bracket 27 mounted on the front bar 14 is provided with an elongated slot 28, through which the shaft 19 passes and serves as a guiding and limiting means for the swinging frame 17. A coil spring 28" secured at its ends to an upright 11 and the swinging frame 17, normally holds the frame in a rearward position, while the frame 17 is provided with a catch 28 adapted to be engaged by the hooked end 29 of a pivoted lever 30 to hold the swinging frame in a forward position with the driving cone 20 in operative engagement with the bobbin 31, and a handle 17 a is secured to the frame 17 and extends forward- 1y to a convenient point to permit the operator to swing the frame forwardly into operative position from the front of the machine. r

A bracket 32 is secured to the front face of the front bar 14 and is provided with guide ways upon which is slidably received the bobbin carriage 34, upon which is mounted a stationary bobbin spindle 35 which preferably is tapered as shown in the drawings to fit within the tapered hole of the bobbin 31. One side of the carriage is provided on its lower face with a series of ratchet teeth 38 adapted to be engaged by a pawl tooth 39, which projects upwardly from a lever 40, pivoted at one end as at 41, to the. bracket 32 and terminating at its other end in a handle 42, a coiled spring 43 being provided between the lower face of the lever and a laterally extending lug 44, to hold the pawl toot-h 39 normally in engagement with the ratchet teeth 38. Situated in a slot 45, at the rear end of the bracket 32, is an idler sheave 46, over which is passed a rope or wire 47, one end of which is secured to the bobbin carriage, and to the other end a weight 49. The purthe position shown in Fig. 1.

10, is a small spindle 51, upon which .is.

rotatably mounted a collar 52, the spindle preferably beingprovided with ashoulder to hold the collar spaced from the-bracket. A piece of wax 53 is rotatably received upon the spindle =51 and-restsupon the collar 52, weights 5%. being. provided, if desired, to hold the wax downwardly upon the collar. Av small-hooked wire 55 is. secured'to the bracket and serves to guide the thread or yarn 56 from any suitable .supply, such as indicated by the numeral 57, to the wax applying device, the yarn being passed between the upper face-of the collar 52 and the under face ofthe wax 53. The hook 55 is located to one side of the axis of the spindle 51, while upon the other side of said spindle at a point substantially diametrically opposite of the hook 55, is a sec ond guiding hook 55, which extends downwardly to one side of the inner face of the bracket 50' and is pivoted as at 58-to one end of a small counterbalancing lever 59. The lever 59' is pivoted as at 60, to the lever 30, and when the yarn 56 is passed through the hook 57, inits passage from the hook 55 to the reciprocating thread guide 61, itis engaged'under the hook 55 holding the counterbalancinglever 59 in Should the yarn supply become exhausted or should the thread break it would be evident that the tension in the yarn beingreleased. the lever 59rwoulddrop upon and cause the lever 30 to swing upon its pivot thus releasing the hook 29 and permitting the spring 28 to move the swinging frame 17 rearwardly and release the driving cone 20 from engagement with the bobbin 31, it being understood that the pawl 37 being in engagement with the ratchet teeth 38 will prevent the bobbin from following the. driving cone.

Means are also provided for releasing the driving engagement of the driving cone and bobbin when the amount of yarn wound upon the bobbin reaches a predetermined diameter and comprises adownwardly projecting lug 30 upon the lever 30 located in alignment with the weight 49. VVhen the carriage 34 is moved outwardly by the increasing diameter of the yarn wound upon the bobbin, the weight 19 will move up wardly, as will be obvious, until the upper face of the weight reaches the lug 30, thus swinging the lever 30 and releasing the book 29.

The thread or yarn guiding hook 61 is formed upon the end of a small metal rod 62, which is slidably and adjustably received in one end of pivoted lever 63, which is ad-iustabjly secured to atransverse shaft 64. rotatably mounted in journal brackets secured to the uprights 11. Secured adja cent one end of the shaft Gale a crank lever 65 to which is secured the upper end of a rec-i-procatingrod 66 slidably mounted in the brackets 67. The lower end of the rod 661 issecured to ap-late70 having aguide rod 7 2 slidably mounted in brackets 67. A crank disc 73 is secured upon a short jack shaft 71, suitably journalled on one of the uprights 11 and secured to the jack shaft isia belt pulley 74, a belt 75 being trained aroundithe. pulley 7a and a driving pulley 76 secured to the main shaft 16. The'pulleys 7 1:. and 7 6 are so proportioned, as to produce about three revolutions of the bobbin to one complete reciprocation of the.

thread guiding hook 61;

The operation of the deviceisasfollows,

assumingthe parts are in theposition shown inFig. 1, the swinging frame17jbeing held in its forward position the driving cone 20 is in engagement with the bobbin 31, the bobbin being held in frictional engagement with the cone by the weight 4-9. The rotation of the bobbin winds the yarn 56. there on. and the reciprocation of. the guiding hook 61 guides the yarn and causes itto be distributed uniformly and evenly upon the. bobbin. In order to insurethe proper winding of the bobbin, quick return movements at the ends of the stroke Of-tllifi guiding hook, are essential, as well asuniform speed at the intermediate points. Asthe size of the bobbin increases the bobbin carriage 34 will move outwardly, the pawl tooth 39 being depressed at intervals by the ratchet teeth 38 and moving downwardly against the action of the spring 43. When the weight t9 engages the lug 62, the hook 29 will be released'from the catch 28" and the swinging frame will move inwardly under the action of the spring 28 releasing the driving engagement of the cone 20 and bobbin, it being understood that the engagement of the pawl and ratchet will prevent the bobbin from following the cone. Should the yarn supply 57 become exhausted or the yarn thread" 56 break, the release of the tension in the yarn will permit the counterbalancing lever 59 to drop and release the hook 29-. After placing an empty bobbin upon the spindlet35, the operator grasps the handle 17 and pulls the frame 17 forwardly until the hook 29 is engaged, the yarn thread is threaded through the hooks 55, 57 and Gland between the wax 53 and collar 52, a few turns of the yarn is wound around the bobbin, and the handle 12 is depressed releasing the pawl. and ratchet and allowing the bobbin to move forwardly into driving relation with the cone 20.

In Figs. 2 and 3, a modified form of cam means for reciprocating the thread iguiding hook 61 is shown and crank disc 73 provided with a roller 68 which projects into a cam groove defined by the inner wall of a sub stantially figure 8 shaped recess formed in the face of the cam plate 70, and a pair of pivoted plates 81. One of each of these pair of plates is pivotally secured as by the headed screw 82 centrally of each lobe of the 8 shaped recess and each plate is provided with a tail porton 83 which is normally held in engagement with the wall of the recess to project across the cam groove 80 by a bent spring 8% one end of which engages a small pin 85 projecting outwardly from the plate 81, while the other end is bent inwardly and is suitably secured in the screw 8.2. The operation of this cam member is as follows: Assuming that the disc 73 is rotating in the direction of the arrow in Fig. 2, the roller 68 is shown approaching the tail portion 83 of the right hand plate, the continued rotation of the crank disc will cause the roller 68 to move the plate 81 against the action of the spring 84% upon its pivot 82, forcing the plate 81 to rotate upon the cam plate 70, in a counter clockwise direction. The tail 83 will move across the cam groove and will block the central por tion of the groove compelling the roller 68 to pass upwardly and across into the other lobe of the figure eight groove, it being understood that the spring 84 being placed under tension will tend to increase the acceleration produced at this point by the shape of the cam groove.

lVhile the thread guiding hook 61 is shown as pivotally mounted and having an oscillating motion, it will be obvious that it could be mounted for a straight reciprocating motion and as the term reciprocating would also include an oscillating motion, I prefer to use the term reciprocating as referring to the motion of the hook 61.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

A bobbin winder comprising a frame, a bobbin spindle rotatably mounted on said frame, frictional means to drive a bobbin disposed on said spindle, means to feed a thread under tension to the bobbin including a reciprocating thread guide and means to reciprocate said thread guide comprising an actuating rod slidably mounted on said frame, cam actuated means to reciprocate said rod comprisingagrooved cam connected with said rod, a crank disc provided with a cam roller to engage within the cam groove, and means to rotate said disc.
