SPOOLING OR WINDlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 525,085, dated August 28, 1894.

Application filed September 25,1893. Serial No. 486,407. (No model.)

To all whom it may concern: y

Be it known that I, .I oHN M. PARKER, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spooling or Winding Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

In 'the production of spooling and winding machines adapted to the Winding of thread or yarn, but more particularly to theclass termed cone-winders, it has been found desirable to have them provided with means for automatically stopping the spool or cone upon the accidental breaking of the yarn. ySuch stop-motions should be conveniently accessible to the operator or attendant, positive in action and simple in construction. Moreover, the winding mechanism itselfshould be so connected or related to the stop-'motion de-A vice that although the latter controls the Winding to a certain extent yet the cone-driving mechanism may be kept in continuous operation.

In the machine forming the subject of my present invention I have sought to embody devices well adapted to produce the results referred to in the preceding paragraph. That is to say, the cone-driver revolves at a substantially regular rate of speed; the coneholder runs in unison with the driver irrespective of the yarn-load, yet at the same time the holder is adapted to be automatically disconnected from the continuously running driver in the event of the breaking of the yarn, or whenever the spool or cone is filled with yarn. By means of my improvement I am enabled to wind the yarn more compactly, so that when itis filled and compared with a cone of equal size or diameter as usually wound it will be found that the amount of yarn on the former considerably exceeds that upon the latter. i

My invention consists 1n the novel construc- V1 and 2.

tion and arrangement of'devices or instrumentalities co-operating in an organized machine for winding yarn or thread upon a cone in a zig-zag or wave-like manner, as will 4be more fully hereinafter set forth and claimed.

In the accompanying five 'sheets of drawings illustrating my improved spooling or Winding machine, Figure l, Sheet 1, is a front elevation, a portion of one side being broken away or in section. Fig.,2, Sheet 2, is a side view, some of the parts being omitted. Fig. 3, Sheet 3, is an enlarged transverse sectional view,rtaken substantially on line of Fig. 2, showing the stop-motion mechanism. Fig. 4 is afsimilar sectional view of the same showing the relative position of the parts at the instant the tilledcone is about to release said mechanism. Fig. 5, Sheet 4, is a horizontal sectional view, taken on line of Fig. 4.. Fig. 6 is a partial side elevation, in enlarged scale, of the stop-motion device. Fig. 7 is a side view, in partial section, of the traverse motion. Fig. 8 is a transverse sectional view, taken on line oc :r of Fig. 7. Fig. 9, Sheet- 5, is a longitudinal sectional view, enlarged, -taken through the center ofthe cone and arbor, and Fig. l0 is a side elevation of a filled coneshowing the manner of windin g the yarn thereon.

My improved cone-winding machine as a whole is indicated in the drawings by A. It is what may be termed a double machine, that is the parts are so constructed and arranged that two series of cones may be wound simultaneously. As drawn the machine is adapted to build up four cones on each side; it is obvious, however, that its capacity may beincreased by simply extending the ma- Y chine longitudinally. f The two end frames a are united bysuitable ties a', b, o3 and t, Figs. 'Ihe several operative parts of the machine are actuated by the central longitudinal shaft d through the medium of the power-transmitting belt d3 and fast and loose pulleys d', d2. The two cone-driving shafts t', z', are mounted on either side of shaft d vand in substantially the same horizontal plane, a`

gear i4 secured to t he lastnamed shaft rotates one of the shafts t by means of a smaller gear s fixed thereon, see Fig. 2. The latter IOO shaft extends through the front end frame and carries a gear wheel fr" which drives a similar gear secured to the other shaft i, see Figs. 1 and 2; thus it will be seen that the cone-drivers 1I rotate simultaneously at the same rate of speed. To each of the shafts t' are secured four driving wheels h, the peripheral surface being grooved or concave and adapted to frictionally engage with and rotate the cone-holders c4, Fig. 9. These holders are secured to spindles c3 mounted in .bearings h formed in the outer or free ends of swing arms o2 pivoted to the upper frame tie 03, see Figs. l, 3 and 4. The enlarged or base ends cof the holders are convex and tit into the grooves of the wheels h. If desired the driving surfaces may be covered with leather, c, or other suitable material for increasing the frictional contact. Each of the holders c1 is adapted to receive a readily removable cone-shaped quill c or spool on which the yarn or thread .e is to be wound. The yarn as it unwinds from the cops B passes over a tension roll 7s', and under a drop-wire and thence to the guide-eye f4 of the :traverse arm f jointed at its lower end f (Fig. 6) to the long horizontal traverse-bar f. The device for actuating the traverse-bar is constructed as follows: To the rear end portion of the driving shaft d is secured a double-actin g barrel cam e having a cam-groove e formed in its periphery, (Figs. l and 2) in which groove a roll e4 is adapted to travel. The cam roll is mounted at the upper end of the inner arm of a forked vertical lever c2 fulcrumed at e3 to thelower portion of the rear end frame; the other or outer arm of the forked portion is connected with and actuates the traversebar; the latter being supported by guiderolls b2 mounted in the upper portion of standards or brackets b secured to the frametie b, see Fig. 2. From the foregoing it will be apparent that the rotation of the shaft d will produce a reciprocating or to and fro movement of the bar fcorresponding to the throw of the cam e; and since the latter is double it at the same time also actuates a similarly mounted traverse-bar located at the opposite side of the machine.

In machines of the class forming the subject of my present invention it is usual to combine a number of single strands or ends of yarn and Wind them collectively to form the cone. In the drawings I have represented the cone as being composed of four strands leading from a corresponding number of cops B xed on spindle-holders m loosely mounted on a fixed rod or shaft m. These strands pass over a slowly revolving tension roll lo secured to a shaft 7c mounted in bearings formed in the end brackets p, Figs. 1 and 2. The brackets are provided each with a'curved slot p carrying a guiderod p3; thumb-nuts p2 being employed to secure the rod in position after it has been adjusted. The strands of yarn in unwinding from the cops pass over the guide-rod to the tension-roll; the tension upon the yarn being regulated by the position of the rod with respect to said roll.

The outer end of the tension-roll shaft 7c is provided with a rightand left spiral groove k2 having a dog 7a4 fitted therein, as seen in Fig. 7. By means of this well known device the revolving roll is given a reciprocating movement to and fro longitudinally for the purpose of varying the position ofthe strands of yarn running over the roll and thus preventing the yarn from grooving or cuttingit. Rotary motion is imparted to the roll through the medium of a small sprocketwheel d5, secured to shaft d, and an endless chain d actuated by said Wheel and engaging `with a larger wheel dl mounted to rotate ona fixed stud als; the inner hub of the last named wheel forms an eccentric di] (Figs. l and 2) on which two connections d10 are mounted, the upper or free end of each being elongated, as at d, Fig. 7, to form a pawl adapted to engage with the teeth of a ratchet-Wheel [c3 secured to the roll thus it will be seen that the large wheel d7 operates to slowly turn the tension-roll intermittingly.

Each of the subsidiary cone-winders is pro vided with an independently operating stop motion device, constructed and arranged substantially as follows: Each of the four threads ,e as it runs over the tension roll passes first under the hooked end a5 of a light dropwire n3 mounted in the vertical frame or bracket D secured to the tie beam b; the

thread next passes over the top rounded edge' s2 of the longitudinal normally stationary guide s secured to the downwardly extending pressure bar s, fulcrumed at s3 to rearwardly projecting arms n4 formed on said bracket D; the thread as it leaves the guide s is combined with the other three threads and runs through the eye f4 of the hinged traverse-arm f and onto the surface of the revolving quill c. It will be seen that each individual thread when running normally supports a drop-wire, the latter carrying a pivotally mounted dog 'a at its lower end adapted when dropped or released to engage the cam g secured to the continuously actu ated rock-shaft g 4extending longitudinally of the machine. The dogs n are pivoted at n2 to a flat sliding dog-plate F; this plate is pro vided with an opening n in which the dogs are mounted, the forward portion of the plate being guided by and extending through an opening formed in the lower portion of the bracket D; said plate is supported by the frame ties and b. The rear portion of the plate is bent or offset laterally (Fig. 5) and provided with an ear h3 in which is stepped a vertically extending rod h2 whose upper end supports the swinging arm 02 carrying a cone-spindlec3. From the foregoing it will be apparent that upon the breaking of a thread the corresponding drop-wire will then instantly' fall, thus placing the dog in position in front of and in engagement with the I o'o IIO moving cam g', which latter causes .the plate F and its attached parts to move toward the front (limited by the cam-stroke), thereby at the same time, through the medium of the rod h2, lifting the free end portion of the arm o? and disengaging the corresponding end cf of the cone-holder from the continuously revolving driver h (see dotted lines Fig. 3), and thus automatically stopping the rotation of the cone. In order to more quickly stop the latter I provide a brakeoadapted to frictionally engage the upper side of the driving end of the cone when the arm o2 is elevated. The relative position of the brake to the conve may be regulated by means of the adjusting screw or stop o4. j

The drop-wire bracket D is provided in front with a pivoted latch u'having a downwardly extending lug 'a4 passing through an opening formed in the bracket. This latch automatically drops into engagement with the plate F and locks the latter in position Whenever the plate is moved from its normal position, or upon the breaking of a thread, see Figs. 3 and 4.

In addition to the arrangement just described forautomatically stopping the rotation of the cone upon the breaking of a thread and the consequent falling of the correspond- 3o ing drop-Wire, I further provide the machine I with a device for automatically stopping the cone when the latter is loaded with v yarn or filled to any predetermined size or diameter. This last-named device consists essentially of a size-lever u fulcrumed to the center of bracket D, its rear end havingl a laterally projecting contact surface or lug u', of suitable length, arranged to rest upon and be supported by a pin s4 mounted in the side of the pressure-bar s, see Figs. 4 and 5. A dog ns, similar to the drop-dogs before described, is fulcrumed to the plate F and is connected to the lever u by a short link ne, see Fig. 4; thus it will be seen that the size-lever dog is adapted to move up and down in unison with said lever. The pressure bar s, as before stated, is jointed to the bracket arms n4 and is enlarged at its lower end to form a counter weight fr in which is secured a laterally projecting pin lr adapted to contact with the upwardly projecting lug r2 having an inclined face and forming a part of the dog-plate F. The weight r insures the normal contact of the guide-eye f 4 with the cone While the latter is being built up, but upon the breaking ofa thread the action of the cam g upon the dropped dog forces the plate F towardy the front,thus bringingthe lugrzinto engagement with the pin r and swinging the bars and the traverse-'arm away from the cone. Now, While the cone is being filled the pressure-bar swings away from the center of it in a corresponding degree until at the moment of the completion of the winding the movement of the bar s will have carried the`pin s4 past the end of the lug u of the size-lever at which instant the latter automatically falls, thereby.

moves the plate F from its normal position;`

the action of the plate being not only to lift the cone and its spindle from the driver but to swing the pressure-bar and traverse-arm still farther away from the cone, all as clearly shown in Fig. 4.

The bent counter-weighted pressure-bar s, as stated, is pivotally mounted to the frame. To the upper end of the bar is-secured a guideplate s' whose upper edge s2 is well rounded and over which the yarn freely passes to the corresponding guide-eye f4; the guide-plate extends the length of the cone `and is practically arranged at an angle with the axis of the holder spindles c3, or in 'other Words the plate itself is set parallel with the inclined surface of the cone. The plate s also serves as a guide for the eye-carrying traverse-arm f', which latter is jointed at f 6 (Fig. 6) to the reciprocating traverse-bar f. The traversearm is kept in normal contact with the plate s through the medium of the bent extension f3, Whose free end bears against the front surface of the plate,-see Figs. 3, 4 and 6. From the foregoing it will be seen that the counterweighted pressure-bar s automatically maintains the guide-eyef4 in yielding contact with the inclined surface of the yarn-load While the guide-eye is traveling back and forth with the vibrating traverse-arm, notwithstanding the fact that the traverse-bar is at the same time moving in a plane parallel with the axis of the cone-holder.

I would state that although the cone itself may be stopped the traverse-bar is kept in continuous operation, therefore the upper end of the traverse-arm f is liable to disarrange or roughen the surface of the yarn wound on the cone and thus destroy the work of the Winder. Now, in order to prevent or guard against the contingency just referred to the lug r2 of the removable plate F engages the pin 1" of the lower portion r of the pivotally mounted pressure-bar s before described and swings the upper portion of the latter toward the front side of the machine, and at the same time by reason of the engagement of the guide IOO lIO

plate s with the front extension f3 of the traverse-arm f the latter is withdrawn from the cone, see dotted lines Fig. 4.

The two cam-shafts g vibrate in unison by` means of the connecting rod Z3,which isjointed to arms Z2 secured to the front ends of said shafts; one of the latter having an arm Z4 to which is jointed an eccentric-rod Z actuated by an eccentric Z secured to one of the conedriver shafts fi, see Fig. 1. f

The operation of my improved cone-Winding machine is as follows:-The cops B are taken from the boxes C and mounted upon the spindles or holders; the end, or ends, of the yarn or thread are next passed, as before described, to the quill c mounted on therevolving holder c, the movementof the latter IZO combined with thatof the reciprocating traverse-arm being so timed as to wind the yarn spirally upon the quill. Now, in case say one of the strands of yarn breaks the dog-plate F will be quickly forced outwardly through the medium of the correspondingly dropped dog n, and traveling cam g', thereby lifting the cone-holder from the driver h and into engagement with the brake o; the lug r2 at the same time forcing the pressure-bar, and guideeye backwardly or toward the front and away from the cone, the latch us meanwhile locking the plate in place. After piecing the broken end of the yarn, thereby lifting the dropped dog into position, the attendant next raises the latch and pushes the dog-plate rearwardly to its limit, thus lowering the cone into action again; the bar s, then returning to the normal position. When enough yarn has been wound onto the cone, as gaged by the parts u and s4, the size-lever falls, thereby dropping the corresponding dog n.8 below the plate F to be engaged by cam g', the action of the latter being to move the plate, thus lifting and stopping the rotation of the cone and at the same time swinging the pressurebar s, and guide-eye away from it as just described. The size-lever may be vibrated by hand as desired by means of the handle u2. The cone when filled may be readily taken from the bearings h and removed from the holder c4; the latter after being furnished with another quill is replaced in the machine, and the operation of filling again repeated. It will be seen that the cone-lifting rod h2 of the dog-plate F is located contiguous to the driving end of the cone, the arrangement being such that the device operates to tilt and stop the rotation of the cone, the opposite end of the spindle at the same time resting in the normally supported bearing carrying the end of the adjacent revolving cone-spindle.

As before stated my improved winding machine is comparatively free from complicated devices, thereby rendering it efficient, easily operated and having great capacity. Owing to the fact that the machine is adapted to be kept in substantially continuous operation, it follows that practically no time is lost in piecing the yarn ends and removing the tilled cones or bobbins.

In some cases winding machines have been provided with mechanism constructed and arranged to actuate each cone or spool individually, that is to say each cone. is rotated by means of a revolving drum, either cylindrical or cone-shaped, the entire face of the drum being in frictional engagement with the yarn-load of the cone during the operation of building. When thus wound it willbe found that the lay or wind of the yarn is not uniform, it being comparatively fine and close, or normal, adjacent to the quill and coarse and open at the exterior; this result is due to the fact that while the motion of the traverse or guide which delivers the yarn to the cone is regular the rotation of the cone becomes slower as it increases in diameter and consequently the cone does not contain as much yarn as one of equal diameter having a constant or tine lay or wind throughout. By means of my improved machine the wind of the yarn upon the cone is uniform; it may be regulated so as to produce a close wind or an open wind as desired by simply changing the relative speeds of the drivers hand traversebar f. Fig. 10 represents a side view of an open-wind cone E, that is the spiral coils or convolutions cross each other at substantially regular intervals thus giving it the appear-4 ance of a reticulated surface; the openings z' being bounded by the superimposed threads z crossing each other, as just stated.
