Specification of Letters Patent.

Patented Nov. 24, 1914..

Application filed September 4, .1908. Seria1No.451,701.

TO aZZ whom it may concern:

Be it known that 1, Simon W. l/VARDWELL, a citizen of the United States, residinglat Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Winding-Machines, of which the following is a specification.

My invention relates to winding machines for winding bobbins or yarn packages of cylindrical body, taper nose and substantially flat base, in which the yarn is laid with a foundation cone consisting of superimposed layers having lengths of traverse. a

My invention consists particularly ofdevices for use in connection with the traverseregulating mechanism of a Windingmachine similar to that shown and described in my pending application, Serial No. 151,700 filed Sept. 4, 1908.

. The accompanying drawings illustrate,

respectively: Figure 1, a front elevationof the device applied to the traverse-regulating mechanism above referred to; Fig. 2, an

end view of the same. k 1

Referring to the drawings, 5 is the traverse cam, which, through suitable connec tions, imparts reciprocation to the yarn depositing guide, not here shown, that lays the yarn on its holder. These connections consist of thelever 12, pivoted on the fulcrum stud 11, with its lower arm extending downward into proximity with the cam 5 and bearing a roll 13 on the stud 1,0, the former engaging the groove 6 of the cam. The stud 11 is secured in the frame of the machine and is formed at its outer end with a pca Washer 411, which, in turn, bears against the end of the hub 12 of the lever 12 to retain thelatter in position on its bearing.

The upwardly extending curved arm of the lever 12 has a slot 14:, on one side of which are formed the rack teeth 15. Fitted to the slot 141 and adapted to mesh withthe teeth 15 is a ipinion 20, whichncarries a ratchet wheel 23 and is rotatably secured to:

one end of a connecting-rod 19. The latter serves as a link between the lever 12 and the traverse-rod 16, which carries the yarndepositing guide, not here shown, but fully gradually increasing illustrated and described inmypending apphcation before referred to. With the pinion 20 in its lowermost position in the slot 14, as shown by full lines inFig. '1, the oscillation of the lever 12 will cause a relatively short reciprocation of the traverse rod 16, owingto the disparity in leverage between the two arms of the lever; but by raising the connecting-rods point of connection with theupper arm of the lever 12, it is obvious that the leverage on the connect1ng-rod,19 will be increased andthe traverse of the rod 16 correspondingly augv mented.

The object of increasing the traverse of the rod 16 is to cause the thread-guide carried therebyto deposit the yarn in layers of gradually increasing length, ,as heretofore explained, and thi'syactionis secured through instrumentalities, which are noted uponuby the yarn as it is laid on the holder in a conical mass of diameter. h t

13y rotating the pinion 20 in the direction indicated by the arrow in Fig. 1, the pinion is caused to travel upward on thearmof the lever 12. This rotation is automatically effected through the means of a pawl22,

which has a finger 21 adapted to engage the teeth ofthe ratchet-wheel 23 each time the lever 12 oscillates toward the right into the position shownby dash linesin Fig. 1.

The pawl 22 is pivoted on a pin or stud 24 and is adapted to swing to carry the finger 21 upward as the wheel 23 travels up on the lever 12. To prevent the pawl 22 from being accidentally moved up out of range of engagement with the teeth on the wheel 23, a guard is provided, which preferably takes the form of a curved extension of the pawl 22. As here shown, the pawl 22 is made of sheet metal, bent in angle form to give 'it the required stiffness and having a U-shapediextension 22, which givesa double bearing on the stud 2 1. A

bushing 22 extends. through the two legs of theyextension 22 and the finger 21 is fastened on the top of thepawl by riveting or any other suitable method.

gradually increasing The meansfor effecting the automatic adjustinent of the pawl 22 to cause it to follow the upward movement of the pinion 20,

so that it may at all times be opposed to the teeth of the wheel 23, consists of a lever A, which carries at one end of its arm 26 the contact wheel 25. The wheel 25 is adapted to bear on the surface of the yarn mass asthe foundation cone is built up of superimposed layers and as the mass increases in diameter, the wheel 25 is moved out, away from the winding spindle. In Fig. 2, the full lines represent the position of the lever A at. the start'of the winding, with the wheel 25 bearing against the tube on which the package is wound, represented by the dash line circle a. The dash lines B represent the lever at the completion of the winding when the base of the cop has grown to the diameter represented by dash lines I).

The means for connecting the lever. A to control the movement of the pawl 22 will now be particularly described and the distinguishing feature, of the present 1nvention comprises an arrangement for automatically disengagingthis means when the cop reaches its predetermined size at the base, so that the pawl 22 is relieved from "further engagement with the wheel 23 and returned to its initial position. v At the end of the arm 29 of the lever A is a ball 30 formed with a shank 31, whichis riveted or screwed into, the right-angle portion 29 A cor *esponding ball 32 is connected with the pawl 22, Thelever A. 1s made of sheet metal, as are practically all of f the ,parts the present structure, to make them relatively light, so that there will be no undue resistance to the movement of the mechanism from the wheel 25, which presses the cop. if the parts were of any considerable weight, an extreme resistance to .the movement of the wheel 25 would cause the latter to sink into the comparatively soft yarn mass and the shape of the package would become irregular and the yarn imght be injured. 1

Connecting the lever A with the pawl 22 is a link 3% consisting of two halves formed of sheet metal of trough-shaped section to provide for stiflness, and having spoon-shaped sockets at each end to receive the balls 30 and lilidway between the extremitiesof the halves, are formed two concave indentations 3 l 3-i, adapted to receive the ends of a spring ring 35, which serves asaclip to hold the two parts of the link together, and

provide a yielding friction on the balls.30:

and 32. The linlr 34. gives a positive connection between the operating parts, wlth un1 versal joints at each end, winch prov1de for a smooth movement without play or back lash. It will also be noticedthat .the parts are extremely light, yet so formed as to give proved device now shown, I provide means for releasing the'pawl 22 from the lever A after it has been carried to its extreme upward position, so that it will not continue to engage the ratchet-wheel 23.

In my previous invention the ball 32 is mounted on the pawl 22, but in the present device, I employ an intermediary connection which consists of an auxiliary lever 4-3 to carry the ball. The lever 1 3 is preferably formed of sheet metal with a disk-shaped counterweight 44 at one end and bent double at the opposite extremity at 45, in iJ-form,

to provide a bearingon the stud 24. Re-

ferring to Fig. 2, the drawing shows a bushing {l6 secured in the two extensions of the bent portion 45, similar to the manner in which the brshing22 is fastened in the pawl 22., The bushing 4:6 gives a longer bearing on the stud 24:, and abutting its outer end is a wire clip fl? sprung into a. peripheral groove on the stud 24; and serving to hold the lever l3 and pawl 22 in place on their bearings. v

The portion 45 of the lever l8 extends parallel to the main farm "for some distance and takes the form of a quadrant 4-8 with two arms 49 and 50 extending from the bushing 46. The ball 32 hasja shank 3;?" which extends through an'ear 5i on the, frontof the lever 43 and is riveted into the lower end of the quadrant 4L8, to provide ,a strut between the two portions of the lever.

as a trigger to raisethe catch 59 and free itfrom the-stop 53. The trigger 60 is engaged by a pin 61 when the pawl 22 reaches its extreme upward position. The pin 61 is preferably attached to, or formed on, a mem her 62 which swivels on a screw 63 so that by loosening the screw the pin can be adjusted to regulate the point of knock-o5 of the latch 57. i

It will be noticed that while in my previous invention, the lever A was formed of two parts, adjustable in relation to each other, in the present invention the lever A is of one piece. The adjustment between therelative positions of the wheel 25 and pawl 22 is now effected throughthe adjustment of the arm 52. It is evident that by moving the stop 53 around the quadrant. 48 to the right, the

, P'ivoted on the bushing 46 is an arm 52, the upper end of which is bent overthe edge of the quad. rant 48 to form a stop .53. The arm 52 is tent rotation.

pawl 22 will be raised in relation to the position of the wheeli25, and vice versa when the stop is moved in the opposite direction.

The operation of my device is as follows: The parts are set with the pawl 22 in its lowermost position bearing on the hub 42 of the lever 12 and the pinion 20 at the bottom of the slot 14. The wheel 25 is set against the tube on which the winding is to be performed, indicated by dash lines a Fig. 2, and the stop 53 adjusted so that it will engage the catch or detent 59. The rotation of the cam 5 causes the lever 12 to oscillate and the wheel 23 is carried over to bring its teeth into contact with the finger 21. The engagement of the finger 21, with the wheel 23 causes the latter to rotate and the pinion 20 travels upon the teeth 15 toward the top of the lever 12. Meanwhile, the rod 16 is caused to reciprocate, through the connecting-rod 19, and the thread-guide carried thereby is traversed back and forth along the winding spindle to lay the yarn in gradually increasing lengths of layers. As the yarn builds up on its tube or holder, it bears against the wheel 25, causing the latter to move downward, therebyraising the arm 29 of the lever A, and through the connection 341:, carryingthe lever 43 upward. The

engagement of the stop 53 with the catch of the latch 57 acts to raise the pawl 22 synchronously with the movement of the lever 13 and. the finger 21 follows the wheel 23 to continue to impart to the latter an intermit= WVhen the pinion has reached a point on the lever 12 to give the predetermined maximum traverse to the thread guide, the trigger 60 comes into contact with the pin (31 and the further move ment of the pawl 22 causes the latch 57 to be 'aised, as shown by the dash lines in Fig. 1, to release it from the stop 53. This allows the pawl 22 to drop back, under the infill-u ence of gravity, to its initial position and the wheel 23'receives no further impulse to rotation, that during the remainder of the operation of the machine, the traverse of the thread guide remains constant. As explained in my previously filed application,

the wheel 23 is held against the face of the lever 1.2by a spring 74, which gives a frictional contact suflicient to prevent the pinion 2Ofro1n moving back from the position to which it has been advanced.

When the package is completed and re moved from the winding spindle, to prepare for winding anew bobbin, it is only necessary to turn the wheel 23 backward by hand to bring the pinion 20 to lowermost position; and to set the wheel 25 against the tube on which the bobbin is to be Wound.

lVhile I have shown the preferred form and arrangement of the parts, it will be understood that modifications might be made in the structure without departing from the scope of my invention; thcrefore,I do not limit myself to the precise arrangement shown and described, but
