FESTUS S. RAND, OF IPROVIDENCE, AND GEORGE N. TAYLOR, OF EAST FROVIDENGE, RHODE ISLAND, ASSIGNORS TO UNIVERSAL WINDING COMPANY, OF PORTLAND,

WINDING-MAGI-IIN E.

To all whom it may concern:

Be it known that we, FEsTUs S. RAND and GEORGE N. TAYLOR, citizens of the United States ..residing---at Providence and East Provi ence, respectively, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Winding-Machines, of which "the following is a specification;

Our invention consists of improvements in Winding machines and relates particularly to friction or drum winders in which the yarn-cop or thread-package is rotated .through frictional contact of its surface with 15 the periphery of a drive-roll or drum.

Our improvements are directed principally to the starting and stopping mechanism of the machine, the object being to provide a more efl'e'ctive and positive control over the winding-spindle whereby the rotation of the cop can be more easily and quickly arrested either upon the breakage .or exhaustion of the yarn or for other cause. A' further object of our improvement is to simplify the structure of themachine, to render it more efiicient and durable in use and to facilitate its manipulation and control.

The method and means for carrying out. these improvements are fully described in the following specification, illustrated by the accompanying drawings, in which like reference characters designate like parts.

In the drawings: Figure 1 is a sideelevationof our improved machine with the gear-casings shown in section to illustrate the driving connections; Fig. Qis an end elevation of the same; Figs. 3, land 5 are detail views of portions of the stoppingmechanism for the winding-spindle; Fig. 6 is a detail view of the means for releasing the yarn from the thread-guide upon the stopping of the machine; and Fig. 7 is an enlarged view of the operating and detentdevices for the sto ping-mechanism, art sectional on the line X of Fig. 1, 100 ing in the direction indicated by the arrow w.

Referring first to Figs. 1 and 2, B desi nates the main frame of the machine whi is provided with bearings for two horizontal" shafts C and D. On the. lower shaft C is fixedly mounted a usual form of traverse-cam arranged above the drive-roll D 1914. Serial No. 824,490.

\ C, adapted to actuate the traversing threadguide E; and held fast on the upper shaft D is the drive-roll or drum D which rotates the yarn-cop or package through peripheral contact therewith. The winding-spindle F which receives the cop-tube f or other shell or holder on-which the package is wound is and; rotates in an end-bearing G. i

Referring to Fig. 3, thespindle-bearing G is. formed with two arms g, g pivotally mounted on a slide or carriage H which is adapted to move uprwardly on a vertical rod h mounted on the ame B. Preferably, the carriage H is formed with two bearings h, 11?, see Fig. 7, fitted to slide on the rod h and spaced at some distance apart to pro- .vlde against their cramping on the rod and preventing a free movement of the carriage. Extendlng horizontally through a hub it of the upper bearin h of the carriage H is a fixed rod or stu h on which is pivotally mounted "the hubs g 9 of the spindle-bear- 1ng arms 9, On the outer end of the rod ht is a co lar I held in place by the setscrews 2', i which arescrewed against the bottom of a recess or slot 72. in the rod, see Fig. 7 The collar I is provided with an arm or extension 2" which carries a brake shoe J pivoted on the pin j and adapted to engage a wheel or disk J fast on the winding-spmdle F. Preferably the shoe J is formed with one or more \l -shaped slots or openings 7, see Fig. 3, adapted to impinge upon the beveled sides of the correspondingly-shaped flanges 3' of the wheel J Figs. 2 and 7 illustrate the bearing G in position with the winding-spindle F directly over the axis of the dr1ve-roll D so that the cop-tube f. on the spindle bears on the periphery of the roll. relation of the arts at the beginning of the winding, an as the yarn builds up on the cop-tube f the spindle F will rise with the increase in diameter of the package causing the carriage H to slide upwardly on the rod 72.. ,The spindle F is normally. carried down into pos tion to engage theperiphery of the cop-tube f with the drive-roll D through the effect of gravity, and preferably weighted means are provided for applying the required premure to the carriage H to Ihis is the normal maintain the surface of the package in fric tional contact with the roll. This portion of the machine, however forms nopart of the present invention and is therefore not .here

shown or described in detail.

gtdrive'n into the side of the carriage H.

' The tendency of the spring 9 is to rock the bearing G in the directionindicated by the arrow 2, Fig. 4, to carry the spindle awayfrom the drive-roll D so that the cop-tube f or its surrounding package, as the case may be, will be freed from the roll'whereby its rotation can be arrested. As the spindle F is swung away from thedrive-roll D in this manner the'force of the spring 9 will carry its brake-wheel J into engagement with the shoe J to cause a friction between the two to check the rotation of the spindle. Referring again to Figs. 1 and 2, the thread-guide E takes the form .of a relatively thin sheet-metal arm supported at its base on a traverse-slide or carriage E.

The upper portion of the guide E is curved inwardly around the face of thedrive-roll D to bring its end 6 in close proximity to the point of contact'of the cop-tube'f on the n roll. As shown more particularly in Flg. 7, the upperextremity of the guide E 1s bent or curled upwardly at e and rounded off along its edge, see Fig. 1, to provide a slight crown on its top. In the center of this crowned portion is a notchor depression 6 which serves as a guiding-eye for the yarn 3 The traverse-slide E on which the guide E is mounted is provided with bearings e 0 fitted to slide on two horizontal rods 6, 6 extending between the sides I), b of the frame B. Passing through the slide E is a stud e which projects downwardly through a second slide-plate or runner E? and carries a roll (2 at its lower end adapted to engage the groove 0 in the cam C. The plate E slides in paralIel grooves Z,Z formed in the horizontal sides of a traverse-frame L, the latter being constructed with depending legs Z, Z straddlingthe' cam C and formed with hubs Z Z mounted on the cam-shaft C.

In our previous application for patent, Serial No. 813,013, filed January 19, 1914, we have disclosed a mechanism for oscillating the frame L about the axis of the shaft C during the reciprocation of the threadguide. The purpose of this device is to intermittntly shift the rollin thecamtermed ribbon-winds.

an interruption of the consonance of movement between the thread-guide and winding-spindle and serves to break up the regularity of the winding to prevent what is For winding cer: tain forms of packages, however, particularly for winding in multiple, where the material is to be delivered by unrolling, this breaking up of the Wind is not so important and the mechanism referred to can be dispensed with. Therefore, for the sake of simplification in the drawings we have preferred not to show this arrangement in the present application. To adapt the machine for use without this traverse-changmg devioe it is only necessary to hold the traverse-frame L in its upright position, as illustrated in Fig; 2, and thesimplest meansfor accomplishing this consists of a screwl extending through theside b of the frame B, see Fig.1, and engaging a suitable hole Z. in the leg Z of the frame.

In winding machines-of this type \it is not usual to provide means for stopping the operation of the thread-guide when the rotation of the Winding-spindle is arrested. That is to say, in drum-winders the general practice is'to allow the threadguide to continue to oscillate even after the winding-spindle has stopped.- When the rotation of the Winding-spindle is arrested on account of the breaking 'of the yarn, the continued reciprocation of the thread-guide -very often interferes with the pieclng up of the ends. If one end still remains in the guide it will be carried back and forth and is liable to be twitched out of the operators hand while he is tying up, or in some cases the yarn m ght be strained or broken. To obviate this condition and make it more convenient for the operator to piece up the ends when winding we have devised a simple and efficlent means for freeinggthe yarn from the thread-guide whenever-the rotation of .the cop is arrested. This consists essentially'of a tilting lifter-device or plate M arranged above the curved portion of the threadguide E with its edge m normally lying on top of the latter, see Fig. 7. The opposite edge of the plate M is turned down at m and overlaps the upper edge of a vertical guard-plate M which is fastened toa portion of the frame B by the screws m in and extends along the front of the drive-- roll D. The lifter-plate M may be sup-- ported in anysuitable manner to adapt its edge m to be tilted upwardly to raise the yarn y out of the guide-e e 6 and as here shown it is rovided wit ears m one at either end, pivoted on suitable pins m held the yarn is broken or exhausted during the in similar ears m bent around from the ends of the plate M.

The twov plates M and M serve as a shield or guard toprevent the yarn from falling down and becoming caught on the guide or entangled in the other operating parts of the machine.

. Referring to Figs. 6 and 7, the lifterplate M is operated through an arm m which carries a screw m adapted to be engaged by an element of the stoppingmechanism of the machine as later described. Preferably the arm wa is formed of sheet-metal and secured to the plate M by the'rivets m or through any other suit- 1 a l e a means. Its downwardly extending portion m is bent back on itself at, m and the screw m is threaded through both thicknesses of the metal. The two overlapping portions m and m are sprung slightly apart so that they bind" on the screw m and serve as a friction locking-means therefor in lieu of a check-nut, while allow ing adjustment of the screw in the arm.

The present machine is adapted to be operated in series or gangs, that is, with a plurality-of units all mounted on a common table or bed and driven from a single main driving-shaft. Referring to Fig. 1, the driving-shaft N here shown extends between the two shafts C and D at rightangles thereto and carries a spiral gear N meshing with a similar gear N on the shaft D. On the outer end of the shaft D is a cone-pulley 0 from which rotation is transmitted to an oppositely-arranged conepulley O by means of a belt 0. The pulley O is mounted fast on a shaft 0' which rotates in a bearing pformedas a part of a gear-casing P. The gear-casing P is supported on the end of the cam-shaft G and incloses a gear p fast on said shaft and arranged to mesh with a pinion p on the inner end of the pulley-shaft 0". The main.

driving-shaft N drives the shaft D through the gears .N, N and rotation is imparted y the pulley O to the pulley O andtransmitted thence throu h the shaft 0 and gears 12, p to the cam-s aft C. As more particularly shown and described in our pending appllcation before referred to, the belt 0 1s ar-' ranged to'be shifted longitudinally of the.

pulleys O, O to alter the speed ratio between the drive-roll and cam throughout the .winding. The purpose of this device is to regulate the change in the wind as the cop increases in diameter, but as this arrangement of the mechanism forms no part of the present invention it y. will not be here described in detail. A

The machine is here shown as adapted to wind in. multiple, that is, with several ends nected one end of a wire link If.

are provided with suitable means, not here shown, for pressing them against the yarn.

From the tension-devices Q, the yarns lead 7 through guide-eyes 7', 1', etc., carried at the ends of tilting drop-wires R. The dropwires R are pivotally mounted on a rod 0*, see Figs. 1 and 7, which extends through hearings in a frame R. The frame R is secured to an upright member B which is either formed as apart of or attached to the main frame B of the machine. Also mounted'in hearings on the frame R is a cross-rod r on which is pivotally supported a wire bail R The-bail R is formed with legs 1' having their ends pivoted on the rod r and a cross-member 0" adapted to be engaged by the ends of downwardly reaching extensions 1' on the drop-wires R. A rod 7' extends across the front of the frame" R above the lower ends of the drop wire R and serves'to limit the upward movement of the latter under the action of the tension on the yarns y. From the drop-wires R the several yarns lead up over a longitudinal rod R held in a bearing 6 on the framemember B and thence are drawn through the eye 0 in the thread-guide E to the "winding-spindle F.

Pivotally mounted on a screw e secured in the frame-member B is a fan-shaped lever S, see Fig. 7, one arm 8 of which is provided with a hole into which is inserted the end of a wire 1" which forms an eXtension of the inner leg 7' of thebail R. A second lever S is mounted on the screw 8 on the inside of the lever S and has a downup I wardly extending arm 8 to which is con- The opposlte end of the "link t is hooked into a depending pawl-member T which is pivoted on a pin t at the end of a lever T. The

lower hooked end t of the pawl T is adapted to be engaged by the ratchet-teeth t of a Wheel or disk T which is fixedly mounted on the cam-shaft C and rotates therewith in the direction indicated by the arrow 3, Fig. 7. A pin t in the lever T is adapted to be engaged by a projection or shoulder t on the pawl T to limit the swinging movement of the latter toward the wheel T The two levers S, S are connected by a screw s reaching through a slot 3* in the lever S and screwed into the lever S, a washer .9 being placed, under the head of the screw. By loosening the screw 8 the relation of the s onthe lever S to the arm 3 of 1 the lever S! can be altered to adjust the position of the pawl T in relation to the teeth on the Wheel T The lever T, on which the pawl T is pivoted, is mounted on a stud t screwed into the frame-member B and is formed with a laterally extending arm' 15 adapted to engage the side of a vertical member or bar U which-forms a part of the controlling-mechanism for the winding-spindle F. I

The bar U is pivotally supported-at its upper end by a stud 'wscrewed into the end of the arm 9 which controls the movement of the spindle-bearing Gr. Substantially midway of its length its side is engaged by a plunger-pin u slidable in a bore a of the frame B, see Fig. 6. A coiled spring a acts to force the plunger it against the bar U, tending to swing it in the direction indicated by the arrow/l, Fig. 7. Extending parallel with the bar U-is a second vertical bar V fastened at its upper end to a lug 72, on the side of the carriage H. lhe

bar V is adapted to slide up and down with the movement of the carriage H and is guided at its upper end in a bearing 6? on the frame-member B. At the lower end of the bar V is a guide-piece 0, see Figs.

1 and 5, held in place by the screws 4/, '0 and projecting through a slot Z) 1n the frame-member B in which it is adapted to' slide. Pivotally mounted above the bearing 6 is a dog-lever W which is adapted to impinge against the sides of 'the bar V to resist the downward movement of the latter and thereby the movement of the carriage H. The dog-lever W is mounted on a pin w driven through the ears 0'' which project upwardly from the bearing 6". The hole w through which the pin to extends is preferably of greater diameter than that of the pin so as to provide a floating hearing for the lever W. One end of the lever W'is formed with an opening w through which the rod V passes and the opposite sides thereof are formed with convex faces w, to as shown in Fig. 7. The oppositeend of the lever WVis formed with a. fingerpiece 10 and is operated upon by a coiled spring to held in a pocket 6 in thebearlng b. The tendency of the spring w is to tilt the lever W to cause it to cramp against the sides of the bar V to resist the down ward movement of the latter. The purpose of this arrangement is to prevent the winding-spindle F from moving downwardly toward the drive-roll D after it has once been forced away therefrom by the growth of the winding, the object being to prevent undue movement or jumping of the spindle liable to be caused by irregularities on the- To maintain the spindle F in place above the drive-roll against the force of the spring g acting on its bearing G the two bars U and V are locked together against the longitudinal movement of one with respect to the other'by means of a detent-device shown particularly in Fig. 7 Set into the side of the bar U and held in place by the screws u]? is a block U formed with a shouldered projection or latch to. The lower edge of the latch w" is adapted to'engage with an opposite detent-shoulder '0 formed on a detent-block V set into the side of the bar V and held in place by the screws o",

0*. Below the shoulder 11 is a beveled face side of the bar V. Pivoted on the bar V by.

astud o is a pawl or trip-lever V having a cam-face o adapted to ride against the edge of the plate U The lever V is formed with a tail-piece 41 which carries a laterally projecting pin o The pin 2: is adapted to be engaged by the toe-piece a of a bent rod Z which is secured in a bearing r on the frame R by means of the set-screw 1". The rod Z is adjustable in its bearing 7* to set the toe-piece .2 at different heights. The purpose of this arrangement is to provide means for stopping the machine when the cop or package reaches its predeterand thence through the eyes 1 at the ends of the drop-wires R. From the drop-wires R the yarns are drawn up across the rod R through the notch e in'the thread-guide E and the ends secured in place on the cop- I tube. To start the machine the operating handle K is pressed downwardly to swing the spindle-bearing G over into position above the drive-roll D. During this movement of the bearing G the bar U connected to its arm 9* will move upwardly and under the influence of the spring-pressed plunger u will be swung laterally to engage its latch u with the detent-shoulder v on the bar V. Previous to this the dog-lever W will have been released to allow the carriage H to slide down on the rod 71. so that the cop-tube f will contact with the drive-roll D and be rotated therefrom. Before the windingspindle starts to rotate there will bemore or less slack in the yarns y and consequently the drop-wires R will not be raised immediately to their normal positions in contact with the cross-rod 1'. Owing to this the bail R is liable to be held in such position that the pawl T, to which it is connected through the lever S and link t, is apt to swing into engagement with the teeth of the wheel T and cause an immediate stopping of the winding-spindle or else a chattering of the pawl against the wheel. To avoid this condition the inclined face '2) of the detent-block V is provided to act on the bar U to cause the pawl T to be held away from the ratchet-wheel. This operation is eifected through the natural inclination of the operator to hold his hand on the starting-lever K for an instant or more after pressing the lever down. This causes the latch a to ride up on the incline 'v" of the detent-block V to force the bar U away from the bar V thereby allowing the lever T to swing downwardly under the influence of gravity tocarry the end of the pawl T out of range of the teeth t on the wheel T Now, when the lever K is released the latch a moves back into engagement with the detent-shoulder '0 and the two bars U and V are locked together to prevent the spring 9' from swinging the spindle-bearing G.

' During the operation of the machine the spindle F is rotated from the drive-roll D which contacts first with the surface of the cop-tube f and then with the periphery of the cop as it builds up on the tube. Meanwhile the thread-guide E is reciprocated back and forth along the spindle through its connection with the cam C and the yarn y is traversed on the cop to dispose it in helical coils in the usual manner well known to those versed in the art. -As the Winding increases in diameter the spindle F is forced away from the drive-roll D with the carriage H sliding upwardly on the rod h. The upward movement of the carriage H slides the two bars U and V upwardly while their detents are held in engagement by the plunger-pin u" bearing on the the rod U. Any tendency to downward movement of the carriage H is resisted by the lever W doggling on the bar V;

en anyone of the yarns y breaks or its supply is exhausted the corresponding dropwire R will fall through gravity and its finger 0' will strike against the bail R This action causes the bail to be tilted to rock the connected levers S, S which, acting through the link if, will carry the pawl T intofl,en-, gagement with the teeth t on the ratchetwheel T as shown in Fig.7. As the wheel T is continuously rotating it moves the pawl T downwardly thereby rocking the lever T to carry its arm t latter from the barV.

against the side a of the bar U. Thisrocking movement of the lever T forces the bar U laterally away from the bar V and disengages the latch u? from the detent-shoulder r As soon as'the detents a and "v are released the spring 9 will act on the arm 9 to swing the spindle bearing G in the direction indicated by the arrow 2, Fig. 4, so that the cop will be removed from contact with the drive-roll D. During this swinging movement of the spindle-bearing G the break-wheel J will be carried into engagement with the brakeshoe J 'and the friction therebetween will cause the rotation of the spindle to be immediately arrested.

The movement of the bar U under the action of the lever T is very slight, just suiiicient to release the latch 14 from the relatively narrow shoulder o but as the end of the latch rides out on the beveled face '0 during the downward movement of the bar U, it will cause a further separation of the That is to say, the

bar U will be carried still farther to the left, I

as viewed in Fig. 7, against the action of the plunger-pin to. This continued lateral movement of the bar U carries its side against the end of the screw m in the arm. m of the lifterplate M and tilts the latter to raise its edge m above the topof the thread-guide E. Through this action the yarns y are lifted out ofthe notch e in the guide and are held away from the latter so that as the guide continues to reciprocate it will not carry the yarns with it or interfere in any way with the loose ends. When the rue back into place below the top of the guide E as illustrated in Fig. 7 In threadingup the ends it is only necessary to let them rest on the edge m of the plate M and'the curved upper edge of the guide E will ride under them and automatically piclf them up in the notch 6 As before stated, the rod Z is adjusted in its bearing r to bring its toe a to a height proportionate to the size of the package desired. Now, as the carriage H rides up on the rod-h with the growth in the diameter of the winding, the bar V sliding upwardly therewith will eventually cause the pivoted mechanism then act to arrest the winding 1,;

operation as before explained.

Particular attention is called to the ar rangement of the means spindle away from the drive-roll in a substantially horizontal .direction. 'It will be noted that for supporting the bearing G to adapt the cop to swing the bearing G is pivoted on an axis above 'th'e axisof the drive-roll D so that in releasing the cop from contact with the roll the bearing G is moved laterally'with respect to the vertical plane'passing through the axis of the spindle and roll. That is to. say, it is not necessary to lift the spindle and cop bodily away from the drive-roll,

but only to swing them to one side of their operative position. Heretofore in machines of this type it has been the usual practice to disengage the-cop or package from the drive-roll by lifting it vertically upward therefrom.- This -method of operation entails the raising of a mass of considerable Weight consisting of thespindle, i-ts'bearing and the other supporting mechanism, besides the package itself. On account of this arelatively great amount of energy is required to operate the stopping-mechanism of the machine and usually the operatingsuch arrangements, however, is that the cop or package cannot be stopped quickly. That is to say, it'requires not only considerable energy, but also a relatively longer time to overcome the inertia of the parts which must be lifted in raising the cop of? from the drive-roll and hence its rotation cannot be arrested as quickly as desirable. With the present arrangement it is only necessary to swing the winding-spindle to one side of its normal position and very little energy is required since the weight of the spindle, its bearing and the cop always remains suspended from above. For this reason a light,

quick-acting spring can be employed for op erating the spindle-bearing, and the stopping operation can be effected without other power and with great speed. This quick action of the stopping-devices is of utmost importance, because if the rotation of the copis not arrested very promptly the ends of the broken yarns will run into the package. If the ,broken ends are lost in the winding it requires considerable effort to find and pull them off again and sometimes the operator will not take the time and pains required for properly piecing up. For this reason the winding will often be defective with the ends tied together in bunch knots' and therefore the ultimate value of the prod-,

uct is impaired. The present invention overcomes these defects usual to drum-winders and in addition shows-other improvements both in the simplification of the mechanism of the machine and the provisions'for ease and despatch in its operation. The winding is controlled through sensitive devices which anism without departing from the spirit or scope of the invention;
