To all whom it may concern.-

Be it known that I, DIOKERSON G. BAKER, of lVillimantic, in the count-y of Windham and State of Connecticut, have invented a new and useful Improvement in Machines for Winding Cops of Thread, of which the following is a specification.

My invention relates to an improvement in machines for winding cops of thread in which provision is made for successively winding cops or sets of cops upon a spindle and automatically ejecting the wound cops from the spindle as soon as they have reached the desired dimensions.

My invention contemplates in its broadest sense means for automatically starting the winding of cops of thread after the completion of previously-wound cops by providing for automatically connecting with the spindle the threads which lead from the source of supply to the previously-wound cop.

My invention further contemplates means for automatically distributing the power among independent sets of operating mechanisms.

A machine embodying the principles of my invention is herein shown and described and is particularly adapted to the winding of what are termed solid cops directly upon the winding-spindle as difi'erentiated from the winding of bobbins on a hollow core, and I have shown in connection therewith a copejecting mechanism controlled by the wound cop or cops and so interrelated with the movement of the winding-spindle that the movement of the latter is interrupted, while the discharge of the wound cop or cops is effected and promptly resumed as soon as the discharge has taken place.

In the accompanying drawings, Figure 1 is aview of the machine inside elevation. Fig. 2 is a top plan view. Fig. 3 is an end view looking from the left toward the right as the drawing is held in reading. Fig. 4 is an end view looking from the right toward the left as the drawing is held in reading. Fig. 5 is a vertical transverse section on the line 5 5 of Fig. 1. Fig. 6 is a top plan view of the mechanism for stopping and releasing the shaft which drives the spindle and for starting and stopping the shaft which operates the ejector or discharge mechanism. Fig. 7 represents a reducing ear, forming a connection between the drive-shaft and the spindlevertical longitudinal section through the machine.

The frame for supporting the working parts of the machine may be of any suitable size and shape, as the particular conditions may require. In the present instance it is shown as consisting of a pair of heavy end standards A A, connected by a bed-piece A The drive-shaft B is mounted in suitable bearings'in the uprights A A and is actuated by a drive-pulley b, fixed thereon, which is connected with a suitable source of power (not shown) by a belt I).

The drive-shaft B communicates a vibrating motion to the thread-guide by means of a cam-disk C, fixed thereon and provided with a slanting face 0, Which bears against shoes d d, diametrically disposed upon the outer face of a yoke D, pivotally secured upon opposite sides of the shaft B by pivots d to the sleeve (i mounted on the shaft B. The shoes d 01 may be conveniently attached to the yoke D by inserting their shanks in split sockets d d and clamping them therein by means of set-screws d al so that they may be adjusted at diiferent distances from the center of the cam-disk C to vary the throw of the thread-guide or to suit cam-disks C of varying diameters.

The shank c of the thread-guide E is fixed in the top of the yoke D, and its upper edge may be provided with any desired number of slots 6 for the reception of the threads leading from a suitable supply. (Not shown.) In the present instance the guide E is shown as provided with five slots c and is adapted to simultaneously wind five cops on the spindle. It is obvious that a less number than five might be wound by leaving certain of the slots 6' out of use for the time being and that a greater number might be wound at the same time by introducing in the place of the guide E a similar guide provided with more than five slots. The vibration of the guide E in the plane parallel with the axis of the shaft B will be made positive by the engagement of the cam U with the shoes at the diametrically opposite points of the yoke, since the thicker portion of the cam-disk will alternately come into contact with the shoe upon the upper and lower sides of the said yoke.

The connection of the yoke D with the sleeve (Z while permitting the thread-guide to freely vibrate in one direction, is such as to cause the sleeve d to positively rock on the shaft B as the guide E is forced away from the winding-spindle by the gradual increase in size of the cops being wound, and this rocking motion of the sleeve 01 is utilized for the purpose of determining the point at which the winding of the cop shall terminate by simultaneously effecting the stopping of the rotary movement of the winding-spindle and setting in motion the ejecting mechanism for removing the cops from the spindle, as will hereinafter more particularly appear.

The spindle-shaft is denoted by F. It is mounted in suitable hearings in the standards A A and is driven from the shaft B by intermeshing gear-wheels f and b fixed, respectively, on the shafts F and B. The spindle G, on which the cops are to be wound, is fixed at one end in the end of the shaft F, and its opposite end projects within a cop-receiving tube g, provided with a friction tongue or tongues g, projecting a slight distance from its interior surface along that portion of the tube adjacent to the terminal point of the spindle G. The thread-guide E for directing the threads to the winding-spindle G is located between the receiving end of the tube 9 and the base of the winding-spindle G, and the spindle itself projects within the tube 9 a distance sufficient to permit a set of cops which may be simultaneously wound on the spindle to be shifted along the spindle within the tube 9 without escaping from the end of the spindle while a new set of cops is being wound upon the spindle. It is to be understood that in speaking of a set of oops I intend to include the winding of a single cop at any time in place of a plurality if for any cause it should be found preferable so to do. From what has hereinabove been stated it will be seen that the arrangement is such that when a set of cops just wound is slid longitudinally along the spindle toward its free end within the tube g, by means of an ejectin g mechanism which will be hereinafter particularly described, it will force a previous set of cops which has been temporarily permitted to remain on the spindle G, within the tube g, off the end of the spindle into that portion of the cop-receiving tube g which is somewhat contracted by the tongues g. This will hold the set of cops which has been discharged from the spindle against a rotary movement, and the result will be that the threads connecting the individual members of the set of cops which is held within the tube with the set of cops located on the spindle G, within the mouth of the tube, will be twisted off intermediate of the members of the two sets of cops, one held within the tube and the other rotating on the spindle, while a new set of cops is being wound on the spindle opposite the guide E.

The ejector consists of a depending arm 11, embracing at its lower end the spindle Gand fixed at its upper end to a longitudinally-reciprocating bar h, mounted in suitable bearin s in the upper portions of the standards A A and operated by a depending stud h, preferably provided with an antifriction-roller, as is common, which enters a cam-groove 7L2 in the face of a drum 71 fixed to rotate with the sleeve h, mounted on a tubular box f, within which the spindle-shaftF rotates. The sleeve 72/4 has also fixed to rotate therewith a wormwheel h, which is driven by a worm h on a vertical shaft 727, the latter being provided with a worm-wheel h which is driven by a worm b on the sleeve 12*, mounted on a tubular box I), within which the shaft B rotates, and provided with a clutch member I), which engages a clutch member 12 on a sleeve 19 on the shaft B, and having fixed to rotate therewith a drive-pulley b, adjacent to the drivepulley b, hereinbefore referred to. The sleeve Z2, carrying the clutch member I), is pressed toward the clutch member 12 by means of a spring b and the effect of the spring-pressure upon the member b is regulated by means of a tail-nut I), mounted on the screwthreaded end of the nipple Z2 which surrounds the sleeve b and is held in position by a clamping-plate I). As the tail-nut Z9 is turned in one direction on the nipple Z9 it will force the clutch member 19 away from the member b against the tension of the spring b and as it is turned in the opposite direction it will permit the spring 12 to exert a greater pressure upon the member 11 It fol= lows, therefore, that when the drive-belt b is shifted from the drive-pulley?) onto the drivepulley b the rotary movement of the sleeve 19 imparted to the clutch members and to the sleeve 19 will rotate the worm b and hence the worm-wheel it and hence the worm h on the shaft h and hence the worm-wheel Won the sleeve h, carrying the drum 7L3, which by its rotation will force the bar it, carrying the ejector, to the limit of its advance stroke to crowd a set of cops into the mouth of the tube 9 and back again into normal position. (Shown in Fig. 1.)

The drive-belt is automatically shifted at the proper intervals from the drive-pulley 6 onto the pulley b and back again onto the pulley b by mechanism under the control of the guide E, as follows: A drum K is mounted on the sleeve h, with one of its ends adjacent to the end of the drum h and in the periphery of the drum K there is formed a camgroove for the reception of a stud 70, projecting from the arm Z of a belt-shifting lever pivoted to a suitable support at L and having its arm Z provided with a cross-head Z carrying a pair of studs or pins Z 1 for e11- gaging the opposite edges of the belt I). The

drum K is held under spring tension tending to rotate it in a direction to shift the belt from the drive-pulleyb onto the drive-pulley b by means of a coil-spring k (see Fig. 5,) one end of said spring being secured to the sleeve M, which rotates with the drum h and the opposite end to the drum K. The drum K is, however, prevented from rotating under the tension of the spring 76, except at the de sired intervals, by means of a catch I, fixed to rock with the sleeve (i to which the guide E is yoked, the nose 2' of said catch I (see Fig.

3) being adapted to engage a shoulder on a cam-disk 7c, fixed to rotate with the drum K. The catch I is held against the periphery of the cam k and the guide E against the periphery of the cop being wound at the desired pressure by a spring or weight, in the present instance by a spring R, connected with the end of an arm r, projecting from the sleeve, which carries the catch 1 and the guide.

From the above construction it follows that as the guide E is forced away from the spindle by the gradual increase in diameter of the cops which are being wound it will rock the sleeve 01 and hence the catch I, gradually away from the cam-disk 71: until when the cop has reached the desired diameter the nose iof the catch will escape from the shoulder I6 and thereby set the drum K free to rotate under the tension of the spring. drum K rotates it will during its first halfrevolution rock the belt-shifting lever in a direction to shift the belt from the pulley 1) onto the pulley b and the rotary movement of the drum K will be temporarily arrested at the limit of such half-revolution to hold the belt for a time upon the pulley b by means of the engagement of a lug k on the periphery of the drum K, adjacent to the end of the drum with the nose on of a springactuated dog M pivoted to a suitable support at m. (See Fig. 5.) The said drum K will be again released and permitted to complete its revolution under the tension of the spring 70 when the drum 7L nears the completion of its revolution by the engagement of a lug it on its periphery adjacent to the end of the drum K with the nose on of the dog M. The outer end of thelug 70 is rounded, so that it will not catch the nose of the dog, but will pass beneath it and gradually lift it back out of engagement with the lug k on the drum K. It is obvious that that portion of the nose m of the dog M which is opposite the lug k on the drum 72 might be rounded and the lug 79 left squared, if such reversal were found desirable. lVhen the drum K is so released by the rotary movement of the drum 72. it will complete its second half-revolution and in so doing will rock the lever L into the position shown in Fig. 1 to shift the belt back again from the pulley 5 onto the pulley b, and thus will again start the rotary movement of the spindle. Since the aotuating-spring7t is secured at one end As the to the sleeve h, which rotates together with the drum h the rotary movement of said drum 7L3 will serve to wind the spring and keep it wound, so that it is at all times ready for action to turn the drum K. The drive-pulleys b and b are promptly brought to a stop, when the belt is released therefrom, by means of brakes S and S, which are slid toward the faces of the pulleys by the inclined ends of the belt-shifting pins Z Z with the beveled ends 3 s of the sliding brakes S S as the belt-shifting lever is rocked back and forth. The sliding brakes S S are promptly thrown out of engagement with their respective pulleys when released by the belt-shifting pins or studs Z 1 by the frictional engagement of the face of the pulley with the brake, tending to slide it away from its face. The relation of the belt-shifter to the brakes is clearly shown in the detail plan view, Fig 6. The tension device for holding the several threads under the proper strain as they are fed to the windingspindle is here shown as consisting of a series of glass or other highly-polished disks 0, held pressed toward one another by a spring 0, the tension of which may be increased or diminished at pleasure by means of a thumb-nut P.

To keep the face of the cam-disk C properly lubricated along the path where it bears against the shoes upon the yoke which carries the guide E, I find it convenient to provide a stick of graphite or other suitable lubricating material Q, supported in a suitable socket q, projecting from the standard and pressed gently against the face of the disk by a spring q within the socket.

The intermeshing gears f and b may be relatively varied at pleasure to make the number of rotations of the spindle correspond to or vary from the number of Vibratory movements of the guide E as may be found desirable. In the form shown in Fig. 7 provision is made for driving the spindle-shaftF a little slower than the drive-shaft B by making the gear-Wheel'F corresponding to the gear-wheel f in Fig. 1 a little smaller than the gear-wheel 13 corresponding to the gear 12 in Fig. 1. This will make the vibratory movement of the guide E and the rotary movement of the spindle non-synchronous, so that the diagonal position of the thread across the periphery of the cop being wound will vary its position during the successive rotations of the cop and add to its firmness.

The operation of the several parts of the machine have been so fully set forth in connection with the foregoing description. that a further detailed statement of the operation is not deemed necessary. The operation may, however, be concisely stated as follows: As soon as the set of cops has been wound on the spindle G of sufficient size to press the guide E back to a point where the catch I will release the disk It and hence the drum K, the latter will complete a half-revolution and shift the belt from the pulley l) to the pulley b and thereby start the rotary movement of the sleeve b and hence the rotary movement of the drum h3 by the intermediate connection of worm-wheels and worms. The rotary movement of the drum its will advance the ejector II and slide the set of cops already wound into the end of the tube g. As the drum 77, nears the completion of its revolution it will set free the drum K, which has already been arrested at a half-revolution by the spring-actuated dog M, and the said drum K will complete its revolution under the tension of its actuatingspring and will again shift the belt from the pulley b onto the pulley b and hence start the winding of a new set of cops. The drum K will be arrested at the completion of its revolution by means of the catch I, the nose of which will catch over the shoulder as clearly shown in Fig. 3. As the second set of cops is slid along the spindle G by the ejector II it will crowd the set previously wound off the spindle into the contracted portion of the tube G, where they will be held against a rotary movement, while the rotary movement of the set subsequently wound during the winding of a succeeding set will twist apart the threads which unite the members of the discharged set of cops with the members of the set on the spindle within the end of the tube. In this manner the machine will automatically proceed to Wind set after set, eject them from the spindle, and sever the threads which connect them with those which have been previously wound.

It will be observed that by throwing apart the clutch members which connect the sleeves for transmitting motion from the drive-pulley b to the ejecting mechanism, the belt being at the time on the drive-pulley b the sleevesection which carries the pulley b will be permitted to rotate idly and the operation of the machine will be stopped without stopping the drive-belt b.
