This application is a division of application Serial No. 657,529, filed October 30, 1911, renewed F ebruary` 10, 1916, Ser. No. 77,525. (Patent No. 1,239,669, issued Sept. 11, 1917.)

The embodiment herein shown of my invention is a machine. for rewinding yarn from a bobbin a or b (Fig. 2) ontocores c to form cheeses d. The winding, detecting and throwing-out mechanisms for each cheese will be herein'termed a. winding unit.,

In the present embodiment, the cores'or cheeses-are rotated through peripheral contact with a roll 2- driven in any suitable manner.

Upon the supporting frame of the Inachine is a series of brackets '4, each mounted so as to be capable of a slight pivotal movement, for a purpose to appear hereinafter.

Divided and this application filed August 15, 1917. Serial No. 186,286.

to the machine framework. As shown in i Fig. 3 the point of pivotal support for each bracket 4 is at one side of its center of gravity, so that the bracket tends to occupy the position represented in said figure.

Each bracket 4 has bearings 8 at its upper end. 9 is a cheese-supporting lever provided upon one side and between its ends with a pivot 10 which is mounted in the bearings 8, said pivot being fast to the lever. At the end of the long arm of the lever 9 is means for rotatably supporting the cheese, which means may be of any suitable character.

The yarn may be traversed back and forth to build up the cheese by any suitable guiding means, as, for example, that fully described in said Patent No. 1,239,669. In the construction shown in said patent, there is fixed in the supporting framework in front of the roll 2 a rail or flange 22 (Figs. 3 and. j

4). At the rear or inner side of said rail is another rail V23, said rails being secured together by screws 24. Between said rails are clamped plates 25 having inclined or cam edges 28. The cam portions 28 are at the limits of the to-and-fro motion of the yarn. The yarn is moved laterally `in one direction by an endless traveling tape 29 having yarn-engaging projections 30 thereon, the yarn `being moved-in the opposite direction .by a similar endless tape 31 having like projections 32. Said tapes travel through guide-ways formed between the rails 22 and 23 and the plates 25. The tapes mav be driven by any suitable means.

ig. 5 represents a projection 32 on the tape 31 as having carried the thread to the right across the periphery of the'cheese, the

projection being shown as forcingthe thread up the inclined or cam surface 28. As soon as the yarn has been carried above the projectlon, the yarn will of course be free from said projection, and the tension of winding pleted the yarn is released from the tape 29 by the left-hand cam surface 28, and is then picked up by a projection upon the tape 31, and` again moved to the right. The

Atapesthus alternately pick up the yarn. and

move it over the periphery of the cheese.

Referring to Fig. 3. lt is desirable to keep the yarn-traversing means and the peripheryv of the cheese close together during the winding operation. For this purpose the bracket 4 is pivotally supported, as' hereinbefore described, and a movement of translation is impartedto the lever 9 by means of a stud 45 on the lever arranged to lie against a cam or guide surface 46 .on the bracket 7, said guide surface being of such form that as the cheese increases in diameter the center of the cheese will move upwardly in such a path as will cause the periphery Aof the cheese to yremain close to the yarnetraversing means.

. The means hereinshown for detecting ex- ,y haustion of the yarn and for throwing the v of an elongated loop, as indicated in Fig.

winding yunit out of operation will now be described. To the forward: arm 9*L of the lever 9 is pivoted a depending link 47, the lower'portion of which may be in the formv l. .Said link is given a tendency to swing rearwardly by means of a weight 48 attached lto an arm 47a on the link. When the thread exhausts, mechanism to be. hereinafter described swings the link 47 to a position within reach of ya continuously' oscillating hook 49 (Fig: 3) which pulls the `link downward'and thereby throws the lever 9 vfrom the position shown in Fig. 8 to that indicatedzin Fig. 9, whereby the cheese is withdrawnfrom the roll and the rotation of the cheese suspended. The hooks 49 are 'l fixed upon ya shaft 50 which may be rocked by any suitable means. l

Upon reference to Fig. 3 it will be `seen that if the bracket 4 were free to swing ywhen the hook 49 acts,vthe pull ofsaid hook would be `mainly!` expended in'an effort to cause pivotal 'movement of the bracket, which effort would be resisted by the stud bearf ing against the cam 46. I- therefore provi e means 'for `locking the bracket 4 lagainst pivotal movement just before the hook 49 acts, whichl means, in the present embodiment, consists of the following 1nstrumentalities: A bearing bracket'56 is fixed to the lower end of each bracket 4. In said bearing bracket is pivotally mounted 4a pivotl pin 57, upon j which is rloosely mounted a bell-crank member 58 having a l 'shoe 59 upon one of its arms and an adjust- 6o able stop 60 upon itsuother arm. Said shoe is adapted to make sliding contact with the periphery ofan abutment or locking` plate 61 fixed upon ythe shaft 50 adjacent to the hook 49, which'plate has a peripheral notch 62y into which the heel,63 ofthe shoe 59 drops. Fixed to the pivot pin 57 is an arm 64 4carrying a pin 65 arranged to be engaged by the link 47 as the latter swings rearwardly. 66 is a stoppin in the bracket 4 `to limit forward swinging movement of the arm 64, and 67 is a stop pin in the forward arm of the bellcrank member 58 arranged to be engaged by the arme 64. The weight of the rear portion of the member 58 is slightly greater than that` of the forward portion of said member, but the weight of the arm 64 when it rests against the pin 66 is sufficient to overbalance the member 58 and cause it to hang in the position shown in Fig. 3. The operation of these devices is as follows: When `the yarn exhausts, .the link 47 swings by gravity against the pin 65 and raises the arm 64 into the position indicated in Fig. 8. As soon as the pin 67 is relieved of the weight of the arm 64, the bell-crank member 58 tilts until the heel 63 rests upon the periphery of the locking plate 61. During the next forward swing of said plate, the heel 63 catches in the notch 62, and continuing movement of said late causes the shoe 59 to make contact wit the plate as represented in Fi 10. Such contact occurs a moment be ore the hook'49 commences to pull downwardly upon the link 47. If in the growth of the yarn mass the upper portion of the bracket 4 has tilted forward, the engagement of the plate 61 with the shoe 59 causes the upper portion of the bracket to swing rearwardlyto a normal position that permits the stud 45 to clear the cam v46. It will be evident that when the shoe 59 lies in-contact with the periphery of the plate 61, the bracket'i ca'nnot swing downwardly upon its pivot 6, and that the downward movement of the link 47 will cause the cheese-carrying lever 9 to swing up and over toward the position shown in Fig. 9.

The hook 49 is represented in its lowest position in Fig. 9. As the hook swings upwardl the lever 9 swings down to the'position s own in said figure, the link 47 bending slightly over a stop in 68. ,'When the hook 49 has risen su ciently, the` link springs out' of the hook into the position indicated in Fig. 9, in which position itis out of the way of the hook. l f

69 is abell-crank lever pivoted at 70 in the bracket 4. The arm 69 of said lever is acted upon by a tension spring 71, while the arm 69" normally bears against a lug 72 cast integral with or otherwise suitably secured to the pivot 10 of the lever 9. When the winding of the cheese is started, the lug 72 stands at an acute angle to the arm 69", the spring 71 being then ableto exert suii-` cient pressure to insure proper driving contactbetween the core and the roll 2. AS the diameter of the cheese increases, the lug 72 turns toward a position at a right ment of the lever 9 away from the rotatory element 2, said means being gradually ren deredv less eiectlve as the cheese increases in dlameter.

Then the'cheese is thrown outoi driv-v ing contact with the roll 2, a lug 73 vfast (itl on the pivot 10 strikes the arm 69h, whereby said arm serves yieldingly to arrest the movement of the lever 9 and to determine the thrown-.out position of the cheese.

The bobbins may be supported in any preferredv manner; herein they are shown as supported in bobbin-holders 74 and 75 (Fig. 2), which Vare arranged in pairs, the pairs of bobbin holders being fixed upon a rod 76 extending longitudinally of the framework. The two holders of each pair support a bobbin being unwound anda reserve bobbin.v For convenience in picking up the end of the yarn on the reserve bobbin, said end may be held in a clamp 77 of any suitable construction carried by au arm 78.

In passing from the bobbin to the vtraverse mechanism, the running thread eX- tends into ape-rative relation to detector means, which vmeansy may be of any'preterred form. Herein I have shown two stationary parallel wires79 and 80 .(Figs. l andl 3) xed tothe bracket 7, each of said wires having an inclined portion l81. 82, respectively, to guide the thread behind the wires 4when the thread is being placed in running position, as will appear more fully hereinafter. A bail 83 is pivoted at 83 'Fig. l) to two adjacent brackets 7 and is provided with a weighted arm 84 and a stop 85 arranged to strike a portion of machinevptrame (see Fig. 8). 'Ihe transverse portion of the bail 83 is adaptedy to lie between the wires 79 and 80, and be snpported by the running thread. A portion 86 (Figs. 1 and 3) of the bail is adapted to lie behind the portion 87 of the link 47 to hold the linkin the position shown in Fig. i3 so long as the thread is running.; yWhen the thread exhaustsl through breakage of the thread orbecause the thread hasbeen whollyr unwound from v its bobbin. the weighted arm 84 causes the bail to swing' into the position shown in Fig. S, thereby releasing the link 47, which immediately The . operation.

The. winding unit may be restored to operative condition by an attendant who ties the. reserve thread to the thread end on the cheese, the new strand thus formed extending from the reserve bobbin to the cheese and in front of the bail 83. The attendant then swings the lever 9 and the bail 83 into their operative positions. When the lever 9 andthe bail 83 are being thus returned to operative position, the new thread. is first carried against the guides 8l and 82, and as the winding tension is placed upon the thread'it slips down said guides to a position behind the wires 79 and 80. 88is a stop to limit lateral movement ot' the yarn in one direction as it passes into running position. f l

The unit may also be restored to operation by a mechanism (not shown) of any suitable character, arranged to travel along Vthe series of winder units..
