T 60% whom, it may concern:

Be it known that we, RIMMON O. FAY, residing at Pawtucket, Providence county, State of Rhode Island, and FREDERICK L. FAY, re-

siding at East Brookfield, \Vorcester county, State of Massachusetts, citizens of the United States of America, have invented certain new and useful Improvements in W'inding-Machines, of which the following is a specification.

Our invention relates to certain novel improvements in winding machines, so calledthat is, machines adapted to automatically wind a continuous length of yarn or thread from a suitable source of supply, as a bobbin, spool, or cop, onto a revolving quill, tube, or cop-holder, the result being to produce a cop or package having the lay or wind of the yarn substantially uniform throughout the cop, the yarn load thus wound being compact and not liable to become broken or disarranged and having the coils or convolutions of the several layers crossing one another, so as to produce a close wind.

We are aware that machines of the class or type forming the subject of this application and capable of producing cop's having a close wind have been devised prior to our invention. A machine of this character is shown 0 and described in United States Patent No. 525,085, dated August 28, 1894..

The object We seek to attain is to produce a winding-machine having a greater degree of efficiency than is possessed by analogous 5 machines heretofore devisedthatis to say, in our improved winding-machine the copholding spindle is vertically arranged and more conveniently accessible to the attendant, the spindle-driving mechanism is less com- 0 plicated, it is capable of being readily adjusted as desired, so as to produce cylindrical or cone shaped cops or packages. Moreover, the machine as a whole is simple in con struction, strong yet light, and comparatively inexpensive.

In carrying out our invention the mato and adapted to receive the yarn from said guide, a laterally-movable frame having said spindle mounted therein, variable driving mechanism for actuatingsaid cam and spindle having its movements automatically controlled bythe cop itself as the latteris built up and increased in diameter, whereby the relati ve velocity ratios of the cam and spindle are maintained, while at the same time the speed is gradually diminished, and a yarn tension device automatically regulated by the said cop, thus reducing the tension upon the yarn while the cop increases in size, all as will be more fully hereinafter set forth and claimed.

In the accompanying three sheets of drawings, illustrating our improvements in winding-machines, Figure l is a front side elevation, in partial section, showing a portion of the machine as in operation. Fig. 2 is a corresponding transversc sectional view taken on line 2 2 of Fig. 1. Fig. 3 is a horizontal sectional view taken on line 3 3 of Fig. 1. Fig. 4 is a plan or partial horizontal sectional view taken on line 4 4c of Fig. 3, showing the driving mechanism. Fig. 5 is a rear side elevation of the spindle-carrying frame, showing the cam through which the speed of the driving-belt is automatically changed. Fig.

6 is a sectional view of the tension device. Fig. 7 is a corresponding side elevation. Fig. 8 is a plan view showing a modification of the belt-shipping device, and Fig. 9 is a sectional view taken substantially on line 9 9 of Fig. 8.

The following is a more detailed description of our improved winding-machine:

We would state in passing that W indicates the winding device proper, the same being mounted in or on suitable standards or legs, as A, the longitudinally-extending top bed or table a, secured thereto, the front upper frame or tie b, and the lower tie m. The length of said table, &c., may be 'made so as to carry a series of the said winding devices W, each capable of being independentlyacti'iated and controlled as desired. In Fig; 1 is represented a portion of such organized machine, the winding or cop-carrying spindles H bein say, about twelve inches apart.

As drawn, a suitably-located oontinuouslyloo revolving driving-shaft s is mounted in the lower portion of the machine, from which shaft is transmitted the power for actuating the several winding mechanisms. To this shaft is secured a yielding driver-pulley F, (one for each winding head or device W,) consisting of the fixed disk fand the slidable fellow disk meinberf, connected thereto by the two transverse pins or studs f on which latter are mounted outer helical springs f adapted to keep the faces of the revolving disks in frictional engagement with and actuate the intermediate power-transmitting and shipper wheel E. The outer portion of the adjacent faces of said disks is beveled divergently, as atf the corresponding portion of the wheel E also being beveled, as clearly shown. y

In Fig. 2 is represented a table at, having depending brackets a secured thereto, in which is mounted a short revoluble shaft a on which latter is secured a yielding driven pulley F, constructed and arranged for operation substantially the same as the pulley F just described. The shaft a is located directly above shaft 8 and so arranged that its speed will vary with respect to that of the driving-pulley F, according to the position of the interposed shipper-Wheel E-that is to say, the latter (mounted to revolve freely on a shaft 12 secured in a yoke 79 of the shipperlever b in turn pivoted at b to a stationary bracket 11) is capable of being vibrated in a vertical tlirection,whereby the shipper-wheel E upon being elevated is withdrawn a corresponding extent. from the lower or driving pulley, thus increasing the speed of pulley F, a reversal of the operation producing a reduction of the speed ratio, the function of the springs f being to insure frictional engagement of the working surfaces of the several pulleys.

The cop-spindle H,&c.,soon to be described, as well as the cam U, revolve at different predetermined rates of speed, the former being much the faster. tive diameters of the said pulleys F F and shipper-wheel E such that when the wheel E is in the lowest position, substantially as shown in Fig. 2, the cop-spindle will be driven at its minimum speed. Said pulley when elevated into a corresponding engagement with the pulley F will rotate the spindle at substantially the maximum speed, or, say, seventy-five per cent. in excess of the minimum. The relative velocities of the cam and copspindles to each other, however, remain the same, as before stated. Upon elevating the wheel E until it is wholly disengaged from the revolving. driving-pulley F the winding-head \V will be instantly brought to a state of rest. This is readily effected by 'simply depressing the handle 11 of the shipper-lever. The said front frame b is provided with upper and lower ways, in which the carrier-plate B is mounted edgewise and adapted to slide longitudinally therein, the extent of said movement being We prefer to make the relaat least equal to the maximum thickness of the yarn load capableof being wound upon the cop. At the proper point the frame I) is provided with suitable bearings for the vertical revolving shaft 0 The latter extends above the table or bed aand has secured thereon the barrel-cam C, the same having a continuous cam-groove 0 formed in its peripheral surface capable of imparting the proper reciprocating movement or transverse action to the light vertically-guided yarn-guide d. This latter has a cross-head d, adapted to slide freely in vertical ways (1 secured to the exterior of the stationary cam-casing c removably fastened to the bed a. The casing has a vertical slot through which the yarn-guide extends. It also supports a freely-turning vertical roll 01 located contiguous to the yarn-guide. (See Figs. 1 and To the front side of said carrier-plate B is secured a frame or housing H, in which are mounted upper and lower bearings h h respectively. (See Figs. 1 and These bearings form suitable supports for the revolving cop-spindle H. In case itis desired to produce a cylindrical-shaped cop or package the axis of the spindle will stand parallel with that of the said guide-roll 01 as shown in the drawings. In order to produce cone-shaped cops, the spindle is provided with a correspondingly-shaped tube or quill, followed by loosening the securing-screws h of the housing,

H and swinging the latter until the side of the tube is parallel with that of the guideroll, the slotted openings 77. at the same time readily permitting the adjustment to be made, after which the screws are retightened.

Owing to difference in size, quality, and kind of yarn or thread to be wound into cops,

'we deem it desirable to provide the machine with means whereby the normal rate of speed of the cop-spindle may be slightly increased or diminished in a very close and accurate manner, and this, too, independently of the change in speed, due to and effect-ed automatically by the cop itself as it increases in diameter. Mechanism for thus adjusting or regulating the speed of the cop-spindle is as follows: The cop-spindle H has a belt-driven pulley I secured thereon, as shown in Figs. 1 and 2, and inclosed in the casing H. The said pulley consists of the combined hub and head or top portion t", the vertically-slidable tapering rim member t, having its upper edge adapted to enter an annular or guide groove 1?, formed in the outer part of the said head i, and suitably-mounted interior springs 11 intel-posed between the partst' t" for keeping the latter normally separated. The lower end of the pulley-hub is screw-threaded and provided with an annular nut i By turning the nut in the proper direction the pulley-rim will be forced upwardly into said groove 0?, (resisted by the springs 6 thereby slightly reducing the working diameter of the pulley-that is to say, the outer face of the pulley-rim is beveled, its greatest diameter being at the top edge, the range of movement afforded by the depth of the said groove being such that as the rim is elevated the traveling tlat belt at will impart a slightly-accelerated speed or lead to the spindle, the degree of adjustment being accurately secured by the nut i the latter being accessible through an opening 1, formed in the casing H. Since the tendency of a traveling belt is to run to the high side of the pulley, we provide the latter with an upper guard-flange, as clearly shown, thereby preventing the belt from leaving the pulley. To the front lower side of the said framehand below the pulley I is secured a bracket k carrying a combined idler and take-up pulley 7c, the same being mounted to turn freely on "a stud screwed into a nut 7r, fitted to slide laterally in said bracket, the adj ustmentbeing effected after first partially unscrewing the stud, followed by resecuring it in position. We prefer to make the face of the pulley somewhat crowning and inclose the same in a suitable casing or guard k all as clearly shown.

The cam-carrying shaft 0 is actuated as follows: To the back of said frame b is secured a bracket g, having ahorizontal shaft 9 mounted to turn therein. To one end of this shaft is secured a wide pulley g while its opposite end carries, as drawn, a spiral toothed gear 9 working into and driving a similar but larger gear g the latter in turn being secured to the vertical shaft 0 fitted to revolve in the frame I) and carrying the cam O for actuating the yarn-guide d. (See Figs. 2 and 4.)

The manner of driving the cam-shaft c and the cop-spindle H is substantially as follows: The endless open belt 00 (see Figs. 2 and 4) passes from the wide driven pulley F, rev0lving in a vertical plane, to and around the idler-pulley 75, adapted to revolve in a horizontal plane, thence around the wide pulley 9 secured to the horizontal gear-carrying shaft g, and from the latter pulley to and around the adjustable pulleyI, (also adapted to revolve in a horizontal plane,) secured to said cop-spindle, and thence back to the pulley F, thus completing the circuit. The pulley k is adapted to be adjusted in a lateral direction, so as to maintain a substantially uniform tension upon the belt, thereby re volving the pulleys without slip. It will be seen, referring to Fig. 4, that the two pulleys F and g are of sufficient width or face to allow a considerable lateral travel thereon of the moving narrow belt 00, said travel correspondingto the maximum endwise movement of the plate B, in which the revolving pulleys I and 7e are mounted. This movement of the plate, 850., is equal to the maximum thickness of the yarn load upon the cop, as hereinbefore stated. It will be seen, too, that as thus constructed the length of the belt remains the same with respect to the pulleys at all times and irrespective of the size of the cop being produced. As thus arranged the pulleys F and g will revolve in opposite directions and the two spindles c and H also in opposite directions, but at difierent rates of speed.

From the foregoing it is clear that as the cop P increasesin diameter, as in building up, it will be gradually forced laterally toward the right, thereby carrying with it the easily-slidable plate 13 and the parts attached thereto. The drawings represent the position and relation of the several mechanisms when the cop is practically completed. In building the cop its traveling outer surface is in substantially continuous frictional engagement with the freelyturning guide-roll 01 the degree of pressure being controlled by the attendant as desiredthat is to say, the attendant simply forces the slidable plate 13, carrying the cop-spindle, &c., endwisein the desired direction, thereby keeping the cops surface in yielding engagement with the guide-roll, the pressure between the two surfaces being due to the force exerted by the attendant. A short rod or handle (not shown) may be inserted in the small openingi, formed in the casing H, thus affording a convenient means for effecting the movements of the parts manually. If desired, a normal degree of pressure may be produced by means ofaspring or weight attached to the plate in any well-known or obvious manner.

The yarn-tension device N, Figs. 6 and 7, possesses some well-kn own features. For example, the fixed stud has its outer end 02 screw-threaded and provided with a nut n adapted to regulate the force of a light helical spring 02 interposed between the nut and the pair of friction-disks 71, thereby producing a normal tension upon the yarn or thread in its passage between thedisks. Our improvement resides in providing the head of the standard or bracket 12 with a fixed camcollar 71 and a loose swinging fellow cam member n interposed between the collar 01. and the adjacent disk n. The collar 11 has a downwardly-extending arm n jointed at its lower end to a rod or link a Figs. 1 and 2, attached to and moving in unison with the sliding spindle-carrying plate B. The tension device N is fixed to the bed a of the machine at asuitable point, so that the yarn twill lead direct therefrom to the eye of the vertically-reciprocating yarn-guide d. (See also Fig. 3.) As thus. arranged it will be seen that the length of yarn between the tensiondisks and said guide remains practically the same at all positions of the guide. Therefore the normal tension upon the yarn is substantially uniform with respect to the guides movements.

the increasing diameter of the cop, the gradual movement of the plate B will by means of the said connection a swing the arm n a corresponding extent, thus slightly decreasing the space between the cam-collars and correspondingly automatically reducing the In view of the fact that the tension upon the yarn should decrease with pressure upon the yarn'between the frictionthe back of the plate B is secured a suitable cam 6 (see also Fig. 5,) adapted to be in continuous frictional engagement with a stud or roll (2, mounted on a collar adjustably secured to the said rod e. A spring e is interposed between the collar and the lower portion of the frame, as shown in Fig. 2. As thus drawn the force of the spring operates to depress the shipper-wheel E and also to.

maintain the roll a in frictional contact with the cam e It is to be understood that the construction and relation of the several parts to one another are such that the jointaction of the spring and moving cam operates auto-.

matically to gradually reduce the speed of the cop and cam spindles as the cop increases in diameter) by gradually withdrawing the shipper-wheel E from the pulley F and forcing it downwardly a corresponding extent into the beveled portion of the driving-pulley F, the position of the wheel, &c., corresponding with the minimum working speed and maximum diameter of the cop being substantially as represented in the drawings.

The manner of operating our improved winding-machine is substantially as follows, assuming first, however, that a cop tube or quillhas been placed upon the spindle H and that a suitable supply-cop j, from which the yarn is to be unwound, is mounted on the sta tionary spindle m secured to a bracket m, in turn secured to the spindle-rail m, and having the yarn or thread 25 passing upwardly from the cop j, through the eye t, then between the tension-disks n to the yarn guide or traveler d, and finally onto the cop -tube. The

plate B is now moved toward the left until the cop-tube engages the roll 01 thereby at the same time swinging the tension-arm n to the left and automatically increasing the friction between the disks n. This movement of the plate also carries the driving-belt a; in a lateral direction a corresponding distance upon the pulleys F and g the attendant meanwhile keeping the shipper-lever sufficiently depressed (thereby contracting the spring a of the rod e) to disengage the shipper-wheel E from the continuously-revolvingdriving-pulley F. Now upon releasing the shipper-lever the force of the said spring elevates the shipper and its rod a short distance or until the roll 6 is arrested by the heel or lower part of the cam 6 the result being to depress the shipper-wheel E, so that its outer portion Will just enter between and frictionally engage the yielding members of the continuously-revolving driving-pulley F and be actuated thereby, the speed of the cop-spindle then being at its maximum. As drawn the relative velocities of the cop and cam spindles are such that the former makes eight revolutions to one of the cam, so that as the cop revolves there will be eight coils or convolutions of the yarn wound upon it during each revolution of the cam or double reciprocation of the yarn-guide (I. As the cop increases in diameter by the additional layers of coils the plate B, &c. will be automatically advanced thereby a corresponding extent,and since the spring 6 serves to maintain the roll e against the under side of the cam c the rod (2, and consequently the shipper-lever, will be forced upwardly in a gradual manner, thereby depressing the shipper-wheel E still deeper into the pulley F, (and consequently withdrawing it from the pulley F a like dis tance,) thereby correspondingly reducing the speed of the driven pulley F and the spindles driven by it. At the same time the forward movement of the plate operates, through said connection 71 and the tension device N, to gradually relax the pressure upon the yarn as the cop increases in diameter. NVhen the cop has attained the desired or maximum size, the winding-head WV is stopped and the now completed cop P removed from the spindle, thus completing the operation.

In Figs. Sand 9 we have represented a modification of the variable pulley I shown in Figs. 1 and 2. In the latter the slight change required in the working diameter of the tapering pulley-rim is effected by forcing the rim into or out of the annular groove '6 the belt a: traveling in a substantially invariablehorizontal plane. In the modified arrangement the traveling belt passes between upper and lower arms 1'', secured to the vertically-guided shipper-rod r, the latter having a spring r at its lower end adapted to maintain it in engagement with the top adjusting-screw T The relative position of the belt on the pulley is effected by simply turning said screw in the proper direction, thereby correspondingly elevating or depressing the belt to the desired point on the tapered surface of the pulleys rim. An advantage resulting from this latter construction is that the vertical adjustment of the belt may be readily effected and without stopping the machine.

While the drawings represent the cam and cop spindles as being adapted to revolve in opposite directions, it is obvious that they may revolve in one direction, since either direction of rotation of the cam C will reciprocate the yarn-guide cl equally well.

We claim as our invention and desire to secure by United States Letters Patent- 1.
