Be it known that I WIIMAMI Vonunnwlmi.- nalga citizen of the 7United States, and resident of Roselle, in the 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 for` wind' or reeling yarn, thread, etc., upon cone bo bins such as are commonly used for knitting machines, which deviceV will be simple in construction, composed of few parts andV which therefore can be manufactured and sold at a low price and will not necessitate a high maintenance ex ense.

Another Objectis to provi e a novel means for reciprocating thekyarn or thread guiding means. A further ob'ect is to provide a means for. automatica y .stopping the lmachine when the yarnsup ly is exhausted. Another obj ect c'is to provi e means for automatically stopping the machine when the bobbin has had a predetermined quantity of yarn wound thereon. vA furtherobject 1s to provide a convenient means for' waxing the thread before it is wound upon the bobbin and Another object is to soconstruct the machine that the bobbin being wound will rest upon a stationa shaft and be rotated there; on by the frictlonal contact of a rotating driving member with its' peri hery.

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

shown inthe drawings, a frame work comprised of the -uprights .10, and 11, lower braces 12, to pieces 13 and front bar 14 is provided. ligounted in journals 15 carried by the lower braces 12 is a Ina-in driving shaft 16 u on which is pivotally mounted a swinging ame 17 provided at its upper end with a pair of spaced journals 18 1n which is rotatably received a short shaft 19. Fixedly secured to the shaft 19 is a driving cone 20, a sheave pulley 21 being secured to the shaft 19 adjacent the upper bearing 18. A laterally projectinglug 22 integral with the frame is drilled to receive securely the headed stub shafts 23 upon whichv are ro tably mounted the idler sheaves24 over :which and the sheave 21 is trained the belt 25 which passes over a driving sheave 26 secured upon the main shaft 16. A bracket 27 mounted on the front bar l14: is provided with an elongated slot 28 through which the shaft 19 passes and serves as a guiding and limiting meansufor the swinging frame 17. A coil spri 28*` secured at its ends to an uplrlight 11 an the swinging frame 17 normally ds the frame in a rearward position, while A the frame 17 is provided with a catch 28D adapted to be engaged by the hooked'end 29 of a pivoted lever. 30 to. hold the swinging frame ina forward position with the driving cone 20 in operative engagement with the bobbin 31, and a handle 17 is secured to the frame 17 and extends forwardly to a convenyuo shown in the drawings to fit within the tapered hole 36 of the bobbin 31. One side of the carriage is provided on its lower-face with ay series of ratchet teeth 38 with which is 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 40 and a laterally extending lug 44, to hold the pawl tooth 39 normally into engagement with the ratchet teeth 38. Situated in a slot 45, at the rear end of the bracket 32,lis an idler* sheave 46, over which is passed a rope or wire 47, one end of which is secured to the bobbin carriage, as at 48, and to the other end ot which is secured a weight 49. The purpose of this weight is to force the bobbin carriage rearwardly and cause the bobbin to engage with the driving cone 20.

Mounted upon a forwardly extending bracket 50, secured to one of the uprights 10, is a small spindle 51, upon which is rotatably mounted a collar 52, the spindle preferably being provided with a shoulder to hold the collar spaced from the bracket. A piece of wax 53 is rotatably received u on the spindle 51 and rests upon the co lar 52, weights 54 being provided, if desired, to hold the wax downwardly upon the collar. A small hooked wire 55 is secured to the bracket 50 and serves to guide the thread or arn 56 from anysuitable supply, such as indicated by the numeral 57, to the wax applying device, the yarn being passed bef tween the upper face .of the collar 52 and the under face of the wax 53. By referring to lFig. 3 it will be noted that'the hook 55 is located to one side of the axis of the spindle 51, while upon the other side of said spindle ata point substantially diametrically opposite of the hook 55, is a second guiding hook 57, 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, in its passage from the hook 55 to the reciprocating thread uide 61, it is engaged un- -der the hook 57 olding the counterbalancing lever 59 in the' position shown in Fig. 1. Should the yarn 'supply become exhausted or should the thread break it would be evident that the tension in the yarn being released, the lever 59 would drop upon and cause the lever 30 to swing upon its pivot thus releasing the hook 29 and permltting 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 fratchet teeth 38 will prevent the bobbin from following the driving cone..

maaier 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 redetermined d1- ameter and comprises a ownwardly rojecting lug 62 uponthe lever 30 locate in alignment with the weight 49. When the 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 adjustably secured to a transverse shaft 64, rotatably mounted in the journal brackets 65, secured to the uprights l1. Secured ,adjacent on end of the shaft 64, is a crank lever 64a to which is secured a reciprocating operating rod 66, slidably mounted. in the brackets 67, the lower end of the rod 66 being provided with a roller 68 adapted to engage in a uniform motion cam groove 69 formed in the outer face of a earn plate 70. The cam plate 70 is journalled upon a short jack shaft 71, suitably secured to one of the uprights 11, and is secured to a belt pulley 72 y to rotate therewith, a belt 73 being trained around the pulley 72 and a drivin pulley 73 secured to the main shaft 16. he cam groove is so formed as to produce a quick return movement of the thread or yarn 4guiding hook 61, at the upper and lower ends of its movements, and a uniform speed of movement intermediate the ends. The driving pulleys for the various parts are so proportioned as to produce about three revolutions of the bobbin to one complete reciprocation of the thread guiding hook 61.

rllhe'operation of the device is as follows, assuming the parts are in the position shown in Fig. 1, the swinging frame 17 being held in its forward position the driving cone 20 is in engagement withl the bobbin 31 the bobbin being held in frictional engagement with` the cone by the weight 49. The rotation of the bobbin winds the yarn 56 thereon and the reciprocation of the guiding hook 61 guides the yarn and causes it to be distributed uniformly and evenly upon the bobbin. lin order to insure the proper winding of the bobbin the quick return movements at the ends of the stroke of the guiding hook, heretofore referred to are essential, as well as the uniform speed at the intermediate points. As the 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 49 engages the lug 62, the hook 29 will be released from the catch 28b and the swinging frame will move inwardly under the action of the sprin 28' releasin the driving engagement of t e cone"20 an bobbin, it being understood that the engagement of the pawland ratchet will prevent the bobbin from following the f 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 counter-balancing lever 59 to'drop and release the hook 29. After placing an empty bobbin upon the spindle 35 the operatorl grasps the handle 17a and pulls the frame 17 forwardly until the hook 29 is engaged, the yarn thread is threaded through the 'hooks 55, 57 and 61 and between the wax 53 and collar 52, a few turns of the yarn is wound around the bobbin, and the handle 42 is depressed releasing the pawl and ratchet and allowing the bobbin to move forwardly into driving relation with the cone '69? in which is received a roller 68a projecting from the side of crank plate 75 secured upon a jack shaft 76 'ournalled in ey 72". bein the upright 11a a driving pul secured to the other end of the jack sha t 76 and adapted to receive a driving belt 73a. An additional guide rod 77 is secured to the cam plate a and extends downwardly therefrom being slidably mounted in the bracket 78. l

A further modified formof cam means is shown in Figs. 9 and l10 which form is used with a cam plate .and crank disc similar to that shown in F' 6,` 7 and 8 the cam plate bei provi ed with upwardly and downward y extending guiding rods similar to the rods 66 and 77. VA sshovvn in Figs. 9 and 10 thecr'ank disc 75a is provided with a roller` 68b which 'projects into a cam groove defined by the inner wall of a substantially figure 8 shaped recess .formed in the face -of the cam late 70b and a pair of pivoted plates 81. ne 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 portion 83v which is normally held in engagement with the wall of the recess to project across the cam groove 80 by a bent spring 84 one end of which engages a small pin projecting outwardly from the plate 81 while the other end is bent inwardly and is suitably secured in the ber is as follows; assumingthat the crank disc 75a is rotating in the direction of the arrow in F ig. 9, the roller 69" is shown appreaching the tail portion 83 of the left hand plate 81, the continued rotation of the crank disc will 'cause the roller 69" 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 70a in a clockwise direction. The tail, 83 will move .across the cam groove and will block the central por tion of the groove compelling the roller 69 to pass 'upwardly and across into the other A lobe of the figure eight groove, it being un-A derstood that the spring 84 being placed un-4 der tension will tend to increase the acceler- 'tioned to produce an accelerated motion of the guide hook 61 at the ends of its strokes and a uniform motion driving its intermedi ate travel. y

While the thread guidin hook 61 is shown as pivotally mounted and aving an osclllating motion it will be obvious'that it could be mountedl for a straight reciprocating motion and as the-term reciprocating would alsoinclude an. oscillating motion. ll prefer to use the term reciprocating as referrin to the motion of thel hook 61.'
