COP-WINDING MACHINE.

SPECIFICATION forming of Letters Patent No. 352,704, dated November 16, 1886. Application filed September 25, 1885. Serial No. 178,152. (No model.)

- To all whom it may concern.-

Be it known that I, GEORGE E. MOCAUS- LAND, of Philadelphia, in the county of Philadelphia, and State of Pennsylvania, have invented a new and Improved Cop-VVinding Machine, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a frontelevation of the central portion and ends of a cop-winding machine having my invention applied thereto, showing also the spool-table. Fig. 2 is a transverse sectional elevation taken on the line 00 a: of Fig. 1. Fig. 3 is an enlarged detail View, showing a holding and releasing device for the faller shaft and arm. Fig. 4c is a detailed side view ofthe same, showing the faller-arm in section. Fig. 5 is a detailed side view of the ratchet-pulleyof the faller-operating mechanism, the shaft to, which it is attached being shown in section. Fig. 6 is an edge view of the same, partly broken away, and a part of the shaft on which it is placed; and Fig. 7 is a detail view of the rod N and segment 0".

The invention will first be described in connection wit-h the drawings, and then the particular feature of novelty will be pointed out in the claims.

The main frame A of the machine is constructed in the ordinary manner, and with the ordinary housing B, of which 13 represents doors. This housing incloses the power-cylinders O O and the lower portions of the spindles D D, which are supported in the rails E E in the usual or in any approved manner. I employ two cylinders, C, (see dotted lines, Fig. 1,) both placed on a single main shaft, 0, for revolving the spindles D, by belts (I, passed around the cylinders and around the whirls d upon the spindles, as shown in Fig. 2.

The machine may be of any desired length to run many spindles; but I have shown in Fig. 1 only four spindles at the center of the machine, where the ends of the two cylinders O'G meet, the remainder of the machine being of the usual construction. One of the cylinders C is provided with a cone-pulley, O, for transmitting motion through the shaft F, conepulleyG, ratchet-pulley G, and belts g and h to the mechanism H, for operating the fallershaft I.

The mechanismH is for slowly turning or rotarily reciprocating the faller-shaft I, for raising the faller-fingers I, for laying the yarn 's upon the bobbins t, and also (after the yarn is laid on the bobbin) for lowering the fingers I, when it is desired to commence a new cop;

and said mechanism H consists principally of the two vertically-arranged worm-shafts J, J, the cross-piece K,placed upon the worm-shafts, so as to be moved vertically thereby when the worm-shafts are revolved, and the connection or pitman L, connected to the faller-arm L of the faller-shaft. I, for communicating the upand-down movement of the crosspiece K to the arm L and faller-shaft I.

The worm-shafts J are threaded or grooved ,to impart a gradually decreasing speed of movement to the cross-piece K, the grooves being wide apart at the top of the shafts and comparatively close together at their lower ends, as shown clearly at k In, Figs. 1 and 2. The gradually-diminishing speed of movement of the cross-piece K is necessary to cause the faller-fingers I on faller-shaft I to rise quite rapidly at first to form. the coreat the bottom of the cop. The remainder of the upward movement of the fallen-finger should be comparatively slow to form the cylindrical portion or main body of the cop, and this .movement is produced by the grooves of low pitch at the lower ends of the worm-shafts J, causing slow downward movement of the crosspiece K. 7 g

The faller-fingers I,-besides.having a slow upward movement While forming the cop, must also have a quite rapid up-and-down vibration or reciprocation through a short space,- to properly lay the yarn on the cop, and this rapid vertical reciprocating motion is derived from the heart-cam M,which acts against the lower end of the pitman L and moves it vertically in bearings a a,in which the pitman is loosely held.

The cam M is made fast upon the short shaft b,which is revolved, for revolving the cam, by

ICO

which is longitudinally grooved,as shown at e, to receive a key or stud in the. central aperture of the wheel (i so that the said wheel will revolve with the shaft e,and move up and 5 down upon it as the cross-piece Kis moved up and down by the worm-shafts J. The shaft 6 in this instance is revolved directly from one of the cylinders G by a belt, f, passed around the cy1inder,thence over and under the guide- 10 pulleysff,and thence around the smallpulley f secured at the lower end of the shaft (2. The gear-wheel c is smaller that the wheel 12*, and these wheels are made interchangeable with each other, and with other gears to be 15 placed on the shafts b e,for changingthe speed of reciprocation of the pitman L, arm L, faller I, and faller-fingers I with relation to the speed of np-and-down movement of the cross-piece K, so that the machine may be adjusted as to speed to suit and wind fine,coarse,

and all grades of yarn, which is one very important advantage of my invention, since by the single machine all kinds of yarn may be copped by simply changing the speed of the revolution 'of the shaft b and the speed of the up-and-down movement of the cross-piece K, which latter is accomplished by changing, in the manner hereinafter pointed out, the speed of revolution of the worm'shafts J, described above.

The shaft F, above mentioned, is revolved directly from one of the cylinders C by the belt 9, passing over the cone-pulley (J on the main shaft 0, and over the cone-pulley G on the 5 said short shaft F; and upon shaft F is placed loosely the pulley G, Fig. 5, and over this pulley passes the belt h, which passes around the pulleysjj, at the lower ends of the wormshafts J J, for revolving them, and also around 40 the pulley k on the short upright shaft Z, for revolving it, and which shaft Z is provided with the crank Z. -The pulley G is clutched to the shaft F,in this instance by the ratchet-wheel m,secured upon the shaft, and the pawls m piv- 5 oted to one face of the pulley to engage with the teeth of the ratchet. The pawls m may be disengaged from the teeth of the ratchet m by turning the ring m, so that byturning.

crank l the pulley G will turn backward upon the shaft F, independently of the shaft, and permit the worm-shafts J to be revolved backward for raising the cross-piece K, and all parts connected therewith, from a position low upon the worms (the position they will 5 occupy when the cops are complete) to the position shown in Figs. 1 and 2the position they must occupy on beginning to wind the cops.

The ring m", by which the pawls m may io be disengaged from the ratchet m, surrounds the ratchet under the pawls, and is held to the side of the pulley by staples m and it is formed with the projections m for lifting the points of the pawls, and is formed with the i 5 side arm, m, for turning the ring. The pawls are prevented from swinging away from the ratchet by the stop-pins m, driven into the pulley, as shown clearly in Fig. 5.

The number of taller-fingers I on the fallershaft I need not be equal to the number of spindles t in the machine, since a wire may extend from one end of the machine to the other through the eyes in the said fingers, as shown in Fig. 2. Two faller-fingers,forinstance, will suffice for as many as thirty spindles.

The shaft I is loose in its bearings in the frame of the machine and in the sleeve n of the arm L, except when held by the dog 0, pivoted to the arm L. The shaft I is notched in line with the dog 0, as shown at q, Figs. 2 and 3, and the lower end of the dog is pressed up by the spring 0, so that when the fallershaft I is turned to bring the notch q in line with the upper end of the (logo the spring 0 will cause the dog to drop into the notch q and lock the shaft and arm L together, as will be understood from Figs. 2 and 3. The outer surface or edge of the dog 0 is formed with projections or teeth 0, and upon the horizontal shaft N is secured, in line with the dog 0,

the segmental rack 03; so that by turning the shaft N by the handle N thereof, Fig. 1, or otherwise, the rack 0 will swing backward and engage the dog 0 and turn it on its pivot and move its upper end out of the notch q. g5 When this is done, the springs O, which are made fast at the lower ends to the frame of the machine and attached at their upperends by straps m to the arms or curved plates P,

attached to the faller-shaft I, will turn the loo faller-shaft and swing the faller-fingers I upward and backward away from the spindles t, so that in case of breakage or tangling of any of the yarns they can be conveniently joined by the attendant,whereupon he will grasp one of the faller-fingers and push downward and turn the faller-shaft forward until retained in its original position by the dog 0 entering the notch q.

The spool-table T and the spools U, roller 11o V, tension-rollers u n, and guides to, supported by the spool-table, are all of the ordinary or of any approved construction.

In operation the yarn passes under the wire joining the faller-finge'rsl, and is attached to the I I bobbin upon the spindle t, as shown in Fig 2, and the cross-piece K is raised to the upper ends of the worms J. The machine being now set in motion the spindles will be rapidly revolved by the cylinders O, and the worm-shafts Jand 12o shaft e slowly revolved by power from the said cylinders or the shaft 0 thereof. The revolution of the shaft 6 will revolve gear-wheels c d and shaft b, and the cam M thereon, which will rapidly reciprocate the connecting-rod L 12 and faller-arm L and vibrate the faller-shaft I in its bearings, which will reciprocate the faller-fingers I, causing them to lay the yarn s rapidly up and down upon the bobbin. The

revolution of the worm-shafts J will lower the cross-piece K, first with a quite rapid movement and then with a slow movement, owing to the difference in pitch of the grooves 70 k. The downward movement of the cross-piece K lowers the shaft b, gear-wheels 0 d cam M, and lowers the connecting-rod Land fallerarm L, which turns the taller-shaft I in its bearings and raises the faller-fingers I, which all the time are reciprocated by the action of the cam M, thus causing them to properly lay theyarn upon the bobbin to form the cop. The bobbin being filledand removed from the spindle and an empty one put upon the spindle, to start with the empty bobbin, the crosspiece K must be raised to the upper ends of the worm-shafts J to turn the faller-shaft I, so the faller-fingers I will first guide the yarn to the lower end of the bobbin.

The raising of the crosspiece K is accomplished by first turning the ring at to disengage the pawls m from the teeth of the ratchet m, which unclutches the pulley G from the shaft F, and, secondly, by turning thecrank Z by hand, which will cause belt h to reverse the revolution of the worm-shafts J, and thus cause them to lift the cross-bar and all parts connected therewith, together with the connecting-rod L and faller-arm L. This done,

. the ring in is to be turned back, to cause the pawls m to again engage'with the teeth ofthe ratchet m, to again clutch pulley G to the shaft F.

In case any of the yarns should break or become tangled, the attendant may grasp the handle I (shown in Fig. 1) of the rod N and turn the rod forward, which will bring the device or segment 0 in contact with the dog 0, and swing its upper end out of the notch q in the. faller-shaft I, thus disconnecting the shaft from the arm L, leaving the shaft free to be turned back by the action of the springs 0, so as to lift the faller-fingers I to or near to the topsof the spindles, so they will not be in the way of or interfere with the attendant in uniting the broken yarns or disentangling them. The yarns being set straight, the attendant will push downward upon one ofthe faller-fingers and bring the faller-shaft I back to position to be locked by the dog 0, when the machine maybe started again for opera- I tion.

when the machine is to be adjusted for yarns of different grades, the speed of revo-' lution of the worms J may be varied for the purpose by simply shifting belt 9 on the conepulleys O G, and the speed of revolution of the cam M may be changed by changing the gear-wheel c and d for larger or smaller wheels, as the case may be. In this manner the machine is adapted for all the adjustments necessary to fit it for copping all grades from'the finestto the coarsest yarn.

lt will be understood that each forward rotary movement of the faller-shaft I is against the tension of the springs O, and that the contraction of these springs keeps the lower end of the connecting-rodL constantly in contact with the cam M. In somecases the rod N ping the machine. In this latter case the segment 0 will be made of considerable length, as shown in Fig. 7, so the longitudinal movement of rod N will not move the segment out ofrange of the dog 0.
