T 0 all. wi -(mi it may concern:

Be it known that f, James F. IORUON, a citizen of the United States, residing in Lowell, in the county of Middlesex and Commonwealth of Massiwlnlsetts, have invented a certain new and useful Im )rovemcnt in Winding-.\lachines, of which the following is a s iecihcation. 1

his invention relates to winding machines such as are adapted to wind arn, threads, wire and the like on cylindrica tubes or hollow mandrels or'on hollow cones.

The principal object of this invention is to adapt the. same, machine to the winding at separate times of both cylindrical and 0011-. ical packages or cops without removal or addition of parts other than the spindle or tube carrier.

fn changing from one form of cop to the other it is necessary to substitute for the spindle previmislyuscd aspindle of the form of the co) to he wound. This requires a change of direction of the traverse of the guide which in such machines rests against the material already wound upon the spindle and in windin a cylindrical package, moves in a line para cl with the axis of thecvlindrical spindle, but in winding a cone or more properly a frnstum of a cone, moves ina line at an an le with the axis of a conical or' tapering spindle.

lhis invention comprises means for instantly adjusting the direction of the traverse of the guide into parallelism with the side of the package. to be wound.

Said invention also comprises means of diminishing the. pressure of the guide upon the cop as the latter increases in size; means of varying the initial pressure of the guide on the cop; stop-motion devices operated by the attainment of the cop to a predetermined size; and other sto )-motion devices operated by the breaking of the material being wound.

Said invention consists in the combination andileviceshereinafterdescribedand claimed.

In the accompanying drawings, on five sheets, Figure 1, is an isometric )crspective view of a part of the left side and front of a winding machine embodying my invention; Fig. 2, a right side elevation of said machine; Fig. 3, a rear elevation of the same with a part of the lower cone broken off to show the gearing which connects the. cam-shaft and the shaft ofsaid cone; Fig. 4, a transverse section, mainly vertical, on tie has 4 4 in Fig. 2, of

the swing-frame and vibrator and a front elevation of the cam; Fig. 5, a plan, partly in horizontal section on the line 5 5 in Fig. 2 of the machine arranged to wind a cylindrical cop; Fig. 6, similar to Fig. 5, except that the cone and adjacent gearing is in plan instead of in section and except also that the machine is arranged to win( a conical cop; Fi 7, a vertical longitudinal section of the driving shaft, its clutch, and the shipping rod on the line 7 7 in Fig. 3; Fig. 8, a vertical longitudinal section of the upper part of the swing-frame and the parts movable therewith on the line 8 8 in Fig. 3; Fig. 0, a plan of a part of the means for causing the guide to traverse.

A indicates a table or standon which a number of winding machines may be supported and B a suitable frame represented as comprising a horizontal: bed I) and rail 1), which connect uprights b b, all of any usual construction.

The spindle-shaft or main shaft C (Figs. 1 2, 3 and 7), is represented as hollow ant mounted in suitable bearings b I) in the frame. The spindl'e shaft C is driven by a belt D from a suitable motor or overhead shaft, said belt running on a loose pulley E which constitutes the hollow counterpart of a cone-clutch, the other counterpart being a cone E which may be prevented from turning on said shaftby any usual means, and is represented in Fi 7 as ircventcd from turning on said shaft )y a collar E", secured as by a set-scrcw e, on said shaft C, said collar and the hub e of said counterpart E each having alternate projections c a and recesses c" a which fit each other, the collar E and counterpart E being shaped like a positive clutch am the cone part E being crowded towards the part E by springs e. The actual disengagement of the part E from the collar F1 is prevented by an annular shouhlcr C on the shaft C. The springs allow the )art I to yield when the hollow cone F, is drawn suddenlv into engagement with it and to avoid shocks which might break the material being wound or injure parts driven from said shaft C.

The friction clutch E E is closed by the longitudinal movement of a shipping rod F which slides in the uprights If I)" and carries a forkf which engages an annular groove (2 in the hub of the part E, said rod F being drawn by a lever-f fulcrumed at f on the upright b and pivoted at f tooneendof alinkf", the

other end of which is pivoted at f to the fork 7. (Figs. 1, 2 and 3). When the frictionclutch is closed, the rod F is prevented from its clutch-opening movement )y a latch-lever G which turns on the upright b and engages a notch f in said rod (Fig. 1), the pivot g of said latch-lever extendingthrough said upright I) and being surrounded by a coiled spring g, connected to said pivot g and said upright in an obvious manner, which normallv swings said latch-lever against said rod F. When the latch-lever is drawn out of the notch j, a spring represented as a spiral spring surroundin the rod F and compressed between the upright b and a collar j, fast on said rod, moves said rod in the op osite direction and opens the friction-clutc i and allows the shaft C to come to rest.

The spindle proper or tube-carrier may be cylindrical as at H in Figs. 1, 2 -5 and 7, or ta porin as at H in Fig. 6, and in either case may be attached to the shaft C by the means shown in Fig. 7, where the spindle H is provided with a shank h which enters the end of said shaft and is prevented from turning therein b a lateral projection h which enters and its a groove 0 on the inside of said shaft. The shank h is retained in the shaft C by a 1on screw it which extends through the shaft anil enters a threaded hole in said shank when turned by the head it, rigidly secured to said screw as by being screwed on tight and brazed.

The cop-tube, whether cylindrical, as h? in Fi s.1 2 and 5 or ta )ering as h in Fig.6, may be ield on the s int c by a screw h which enters the free end of the s indle and has a head h which bears a ainst he outer end of such tube, in the usua manner.

The end of the spindle shaft C farthest from the s iindle carries a fast cone-pulley I, lay

connected )y a bclti to another coneu I, running loose on a fixed stud 'i whic 1 projects from the upright b parallel with the shaft 0, said cone pulle s being of the same dimensions, but reverse with respect to each other.

The belt-shifter J is provided with two forks j y" to engage opposite members of the belt'i and is supported on a stud 7" (bolted to the upright b) and on a screw ywhieh turns without advancin in the upri hts b b" and enters a threaded liole in said shifter, so that when said screw j is turned b its toothed head 7" the belt is moved lateralfy to vary the relative speed of the cones I I, a spring catch 1' engaging the toothed head 7 and preventmg accldental turning of said screw 9' (Figs. 1, 2, 3 and 0). A pinion 'i is secured to the cone 1, concentrically therewith, and engages a gear K, fast on a short shaft in which turns in a sleeve-bearing secured to the upright b. A spurs inion fc is fast on the inner end of said she t 7:.

The cam-shaft Z instead of being journaled in the stationary frame B in the usual manner is re resented in Figs. 2, 5, 6 and S as jOLl1I1tl0( in the auxiliary frame B, the body of which is a hollow rectangle resting on and )ivoted to the bed I) of the frame B by a bolt i), and normally prevented from turning on said bolt'b by another belt I) which passes up through an arc-shaped slot 1) in sand bed I), concentric with the pivot-bolt I) and enters a hole I) in the bot-tom of said auxiliary framej When the bolts b b are loosened, the auxiliary frame may be swung about the belt I) until the belt I) strikes an end of the slot 1).

To the rear end of the cam-shaft Z at the rear of the auxiliary frame is secured the internal gear Z which surrounds the spur-pinion k and engages one or the other side of said pinion, according as the belt I) is at one end or the other of the slot 1), causing said internal gear and cam-shaft to be rotated always in the same direction with said pinion 7c.

The externally-grooved cam L is of common form and is fast on the shaft Z and serves to reciprocate the yarn-guide carrier M. Said carrier M is a tube arranged to slide on a red at supported in the auxiliary frame B and in a horizontal extension which, instead of being rigidly secured to the main frame B, is east or otherwise secured on the auxiliary frame B in a line parallel with the cam-shaft Z and moveswith said cam-shaft into or out of parallelism with the spindleshaft, the traversing motion of the guide being alwa s parallel with the side of the spindle whet \er the spindle be cylindrical or taering. The rod in. is held in suitable blocks 1) secured to the auxiliary frame and is normally prevented from longitudinal move ment 1) a in m which passes down into the block Ii tirough said rod. A slide N receives the rear end of the carrier M and is retained on said carrier between a collar m on said carrier and by a nut 1n: and check-nut m (Figs. 8 and 9) turning on said carrier back of said slide, said slide N moving in a slot 1)" in the top of the auxiliary frame B and having one or more flattened sides a which bear against the walls of said slot and prevent said slide from turning, to keep a )IOjOCtiOll a, with which said slide is provirfed, in engagement with the cam L.

Ihe lower end of the yarn-guide 0 surrounds and is retained on the carrier M by nuts 0 0 and cheek-nuts o o, in an obvious manner, and is also represented as screwed thereon at 0. The guide 0 and carrier M turn together on the rod 1n, the carrier being free to turn in the slide N. The body of the yarn-guide 0 extends radially from the earrior M and is then turned upward at 0" at about right angles (Fig. l), the upturned part having secured to it a bit 0 provided in its upper end with a notch 0 which receives the front end out erod m and at the rear end v arn'inthe ,usual Rainier! 7 The front end i tudinal slit 1), through which the radial part of said guide rejects and in which said radial part slides t e si des of said slit havin parallel external lips o 0 which aflord suitable surfacesfor. the direction of said guide, The case,or'- ido -way P is journaled at the ina bearingfbfi which surrounds the tubular carrier M; concentrically, ,with" said rod and described to turn sufficiently to hold the yarn-guide bite always in contact with the cop-tube or wlth the cop being wound thereon. Arms p, p (Fig. 2) projecting from said case sup ort a carrier-roe parallel with the from the arn-notch o and over this rod, the

- mat'er1al emg wound is drawni Upon the axis of t e ease P and at a uniform distance arm p is adjustably su orted another wire or rod p by its rear end The rod 11 does not extend to the front limit of the traverse of the yarn-guide and its upper surface is arranged so that when a yarn is pieced up and laid on the wire p the longer rear side g of the yagn notch 0 will catch said yarn.

on the-next forwardmovement and carry it beyond the front end of said wire p from which said yarn will then fall into said notch 0 and be carried backward under said wire,

said longer side g being so inclined on the back as to hit and pass under the .yarn in;

the'backward movement of the yarn-guide. This arrangement enables ,'the yarn to he pieced up more 'gyluickly than if the yarn had to be placed in t e guide-notch o by hand.

A tensiomlever Q is journaled on the rear end of the case concentrically with the case P and is provided with an ard -snaped slot q concentric with said case, by means of which and of a. bolt carried in an arm p which projects radial y from said case the relative angular positions of said lever Q and arm 11 may be varied and fixed at will;

A weight g is suspended from a slide which is movable on said lever Q, said slide being adjustahly connected by a link q to a part of the auxiliary frame represented as a fork b which is carried h the auxiliary frame B, said h'nli having roles If, at'difi'erent distances from said slide (1 through one or anothel of which holes q". and a hole I) in said fork b"; pin q is pushed to regulate thedistanee of. the weight from the fulcrum or center of the tension-lever before the comineneement of the cop-winding and by changing the position of said pin (1 from one to another of the holes Q, the initial pressure of the guide on the cop may be varied. As the cop enlarges, the yarn-guide is crowded away from the spindle, turning the case P and raising the tension-lever Q and thus drawing the carrier, and is caused by means hereinafter weight fnear the said tensionlever and diminishing the pressure of said yarn guide on said cop, in order; that the' ends of said eop, such as is likely to occur when a uniform. pressure ,on the 'cop is maintained. 'As a further means of pre venting the bulging oftheendof the cop, I provide means fondiminishing the tension on the yarn as the cop increases inisize.

Tension on the yarn is produced by-two dished 'tension-washersrr which are suported on a horizontal stud b on the bracket with their convex, faces towards each other the yarn passing between said washers, whicirare crowded outward hy vthe expansion of a s ring 1' against a collar 1*" loose on said stud which'washers are retained' between said sides may be varied. The tension devices and their supporting stud are ver similar to crwresponding parts shown in atent No. 664,474, granted to me December 25, IQUO, except as herein stated. In said previous patent the sides of he camslide are represented as hinged to each other at the thin edge of the wedge, but I have shown herein the side r as a springrigidly attached at its lower end to the side 1'. it is obvious that raising the cam-slide R or loosening the nut- 1* will lessen the pressure of the washers on the yarn which passes hetween them and that depressing said enmslide or-tightening said nut will have an opposite eii'ect. j

111 this invention, the cam-slide. it is eonneeted by a )in r to an arm Q of the tension lever Q, said )lll passing through a hole q in said arln and through any one of the holes 7', formed onenhove another in the upper part of said cam-slide, the higher the ho e 1" selected,- the greater the initial tension of the material being wound. As the cop enlarges and the lever Q is raised, the pressureof the tension-washers on the yarn is diminished, in equalize the tension of said yarn which, would otherwise be unduly increased by the increased speed of said yarn due to the en-- largement of the co A rock-shaft S is oin-nailed in a bracket l3" secured on the main frame l) (Figs. .i---(i), and is provided with a radial arm s, the outer end of which is connected hy a. red, formed in two parts 8 s", to a wristin s, secured eeeentrically in the end of the cam-shaft Z, so

that said shaft S rocks in each direction one,=

I have shown in Fig. 4, without intending to limit myself to the articular device repre sented, the up an em portion of the parts as screw-tbreaded to engage a corresponding internal thread in the sleeve or upper part a This construction allows a very slight turnin of said parts 3 son each other at every revo ntionot' the cam-shat t Z when said cam-shaft and rock-shaft are not parallel with each other andalso permits of an adjustmentof the length of said rod or link. Parallel with the rock-shalt S is arranged a vibrator or bar S provided with ears 8 s which surround said rock-shat t and are prevented from moving thereon as by set-screws s s so that said bar 3" swings as theshi'tl't. S is rocked. 7

Above the rock-shaft S and parallel therewith is supported in the bracket 13 a rod 8, on which is hung by means of ears .9. s, which loosely surround said rod, a bar 8 slotted longitudinally. from top to bottom at 8"".

.-\s many drop-wiresTil". ol ctnunmn form, as there are yarns (or other things to be wound on the spindle), are retained in the slot s".b v screws a" s' which pass through loops H in said wires and are free to rise'and tall therein, being normally supported by the tension of the yarns which pass through pigtails or eyes t t in the up )0! ends of said drop-wires. when a \'tltll )reaks, the ct'irresponding drop-wire falls into the path of the vibrator S causing the bar 5' tobe swung in the opposite direction. 'fhe dro wires are so arranged that they can [all on y on one side of'the vibrator.

The bar 5 is irovided with an arm a", the free end of whit-his moved downward by the movement of said bar, said free end being connected by a rod s to the lower armf ol the latch lever (i which lower arm. is bent as shown in Fig. I, so that when the arm a' is drawn down, said latch-lever (l is disengaged from the notch-f and the clu ch is opened, as,
