COP-BUILDING MECHANISM FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 374,816, dated December 13,1887.

Application filed March 10, 1884.

To all whom it may concern.-

Be it known that I, ALBERT BALL, of Glaremont, inthe county of Sullivan and State of New Hampshire, have invented a new and useful Improvement in Cop-Building Mechanisms for Ring-Spinning Frames; and I do hereby declare that the following is a full and exact description of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

The purpose I have in view is the production of practical means for spinning on a spinning-frame a cop to resemble that upon the mule-spindle, and to spin sucha cop by means more simple and less expensive and at the same time more effective than any hereto fore employed. The means I propose are more simple, because complicated machinery heretofore employed is dispensed with, and less expensive in first cost and in maintenance because of its simplicity, and more effective because there is no necessity for unusual care in running the frames or for a separate setting at each time of doffing. The means I propose will not only build up a cop shaped exactly like that of a mule-spindle upon a cop-tube or similar bobbin, but by a ready and simple adjustment the frame can spin a cop onthe conical-base bobbin usually employed for woof in ring-spinning frames.

The novelty in the mechanism hereinafter described consists, principally, in combining a particular sprocket-cam with the chain, in a particular winding-drum with means for ad- 5 justing the length of the chain, and in other operative combinations of parts, all as more fully hereinafter described, explained, and set forth in the claims.

For the better comprehension of my invention reference should be had to the accompanying drawings, in which- Figure 1 is a side elevation of a portion of my ring-spinning frame with my improvements applied thereto; Fig. 2, an end elevation of the same; Fig. 3, a top plan view of the same; Figs. 4 and 5, details of the winding-drum; Fig. 6, a longitudinal section of the usual cop of the ring-spinning-frame; Fig.

7, a similar section of a mule-spindle cop, and

Serial No.123,619. (N0 modelfl which is conical from a point near its larger end to the body, which is a slightly-tapering or anearly-uniform cylinder for the remainder 'of its length, and the yarn is wound upon it in successive layers of substantially the same length along the bobbin vcorresponding in shape with the slope of the conical base, as i shown in Fig. 6. c

What I desire is to dispense with the large conical base to the bobbin or tube, thereby incidentally saving weight and expense in the bobbins, enabling it to carry a greater length of thread, and thereby facilitating and encour aging the spinning of warp or woof on fillingframes. In order that this cop may be built up upon such a tube or bobbin so that the yarn will draw off smoothly and uniformly in weaving, it is essential, first, to build up its butt, which requires a constantly regularly increasing length of each layer of yarn until the requisite slope is attained, as shown in Fig. 8, after which time the length of each series is uniform until the cop is completed, as is shown in Fig. 7. The adj ustmentswhich will enable the traverse of the rail to produce this build certainly and effectively constitute the essence of my invention, which is adapted to be applied to any of the spinning-frames for cotton filling or warp commonly used in this country for the last forty years. For instance, the supportingframe A, the spindle B, its ring C, the rail D, the guide-rod E, the rocker-lever F, the ratchet-wheel K and its pawl O, the cam Land its roller M, and shaft W and its support S, the driving-gear N, and

the lever X are well known, and the operation tion of the chain G, the sprocket-cam H, the

winding-drum I, the worm-gears J and Q, the handle P, and thescrew z, and in their combination and arrangement with each other and with the old and well-known portions of the spinning-frame.

The winding-drum, which is mounted on the lever X, is composed of two parts, the grooved rim I having rotary movement on the hub I, which is keyed or fastened in any suitable manner to the shaft I. This hub I is provided with a face-plate, a, an arm or sleeve, 12, and a set-screw, 4, passing through said arm or sleeve, and which sets against the lug 5 on the rim I. When the set screw is turned in one direction, the lug is moved away from the arm and the drum is partly revolved in one direction. By turning the set-screw the other way the drum is permitted to rotate in the other direction until the end of the sleeve or arm and the side of the lug are in contact. The chain'G is attached to the periphery of the drum I by any suitable device. The preferable manner of fastening, however, and the one I have illustrated in the drawings, is by means of a screw, 2, to which the end of the chain is secured, and which continues down through the rim until it enters agroove on the hub, thus serving to lock the two against lateral but not against rotary movements. The chain passes around the winding-drum and up 1 over a sprocket-cam, H, journaled in a proper hanger, and preferably terminates in a rod, G, an intermediate divided and threaded part of which is held by a turn-buckle, 3, by means of which the rod and its connecting-chain may be lengthened or shortened at will: At its outer end this rod is connected with the counterbalanced rocker-lever F R in the usual way.

The drum I has connected with it a wormgear, J, upon which the worm Q, fixedupon the shaft Q of wheel K and adapted to be turned by the handle I, is operated by the handle P,so that the drum may be more or less rotated at will and the chain drawn in or let out for the purpose of adjustment before spinning.

The adjustment of the mechanism described forspinning cops like those of mulespindles is effected in this wise: Ordinarily,when a cop has been dofled and the ring-rail brought down to its lowest or starting point and the frame begins to spin the cop, the cam L is turned, the winding-drum with its chain is raised up, the counterbalancing-weight carries up the rail as far as the throw of this cam and of the winding-drum and chain will permit, and on a further revolution of this cam the rail follows its motion down. As it goes down, the pawl 0 takes one or more teeth of the ratchetwheel K, thereby, through the shaft Q of wheel K, worm Q, and wheel J, unwinding the drum a little and letting out the chain,so that the rail is not allowed to go down quite as far as its starting-point; but on its next upward traverse it goes a little farther than before, so that each traverse of the rail from the beginning to the completion of the cop is through the same distanceordinarily about one and seven-eighths inch.

In spinning the mule-cop in the method proposed by me it is necessary in the first instance,in order to build up the butt,to have a traverse at the beginning of about one and onefourth inch, starting a little higher up each time and making a little longer traverse each time until the butt has been completed, and then the traverse will be uniform in length, starting a little higher each time, until the cop is completed. In order to effect this constantlyvarying length of the traverse in building up the butt of the cop, when the cop has been dofl'ed and the ring-rail brought down to its lowest starting point and the cam L is turned and the winding-drum I, wit-h the chain G,is raised up,thesprocket-cam H is turned so that its lowest point or shortest radius is upward, and the chain G is practically taken up by it the least and so asto permit a traverse ofonly about one and one-quarter inch. When the rail is carried up as far as the throw of the cam L and the effective length of the chain will permit, one layer of thread will be woundv upon the bobbin or tube. The downward movement of the rail is limited in the usual way by the pawl O and the ratchet-wheel K and the lengthening thereby of the chain,'and thismovement downward of the rail-stops at a point a little higher than the initial starting point; but by the unwinding of the chain the cam H is turned a little, so that it presents a longer radius to the chain G, and the result is that the next traverse of the rail is a little longer than the first and each succeeding traverse a little longer than the preceding until the cam H is in such a position that it presents its longest radius to the chain and thereafter acts like a sheave, and the subsequent traverses of the rail are of equal lengthsay one and seven-eighths inch--until the cop is completed.

In order to get the precise initial adjustment of the cam H with regard to the chain G, the chain is drawn in and the cam thereby changed in its position by means of the setscrew 4, which partially revolves the drum I, and drawn out by means of the turn-buckle 3, or vice versa, until the precise desired position of the cam H in relation to the chain G is attained.

It will be understood that in use not more than one-half of the working-face of the cam H is exposed to the chain. Therefore the same I cam may be constructed so as to give two different builds of a cop by a different construction of working faces, as shown in Fig. 1, where one corner of the cam is shown as rounded and the other corner as sharp. If it position that the traverse of the rail will be of the same length all the time that the cop is wound. \Vhen the mule-cop has been wound and the operator is ready to doii', he winds up sequently brought back to its precise previous I claim as new therein, and desire initial position and n0 setting is required. h

Having thus described my invention, what to protect by Letters Patent, is-

1. The combination of the sprocket-cam with a winding-drum and means for operating the same and chain, the ring-rail to which the chain is connected, the rdeker-lever, and the guide-rod by which the chain is connected with the ring-rail for the purpose of raising and lowering such rail with a variable movement, substantially as described. I
