SPECIFICATION forming part of Letters Patent No. 594,530, dated November 30, 1897. Application filed November 23, 1896. Serial No. 613,085. (No model.)

Improvement in Thread-Winding Machines,

of which the following description, in connection with the accompanying drawings, is a,

specification, like letters and figures on the drawings representing like parts. 7

This invention relates to a winding machine or apparatus especially designed and adapted for winding thread, yarn, or like material upon a cop tube or cylinder, and has for its object to provide a simple and efficient machine capable of running at a substantially high speed and of producing a maximum number of balls of thread or yarn in a minimum time.

In accordance with this invention the machine, as herein shown, is provided with two cop-shafts, which are positively driven at a substantially high speed, as will-be described, independent reciprocating thread-guides cooperating with the cop-shafts and a single cam actuating the said thread-guides. The reciprocating thread-guides are mounted in rotatable carriers, as will be described, which cooperate with an automaticstopping mechanism, to be hereinafter described, and the said camshaft is driven from the main shaft, as herein shown, by means of a belt encircling a preferably tapering pulley on the main shaft and a tapering pulley on a counter-shaft, which-latter shaftis geared to the cam-shaft, as will be described. The belt referred to is adapted to be moved longitudinally or axially on the tapering pulleys, so as to vary the speed of reciprocation of the thread-guides according to the size of the thread being wound. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a side elevation of a winding machine or apparatus embodying this invention, the pedestalor support for the machine being represented as broken away. Fig. 2 is an opposite side elevation of the machine shown in Fig. 1; Fig. 3, an end elevation of the machine shown in Fig. 1, looking toward the right; Fig. 4, an end elevation of the machine shown in Fig. 1, looking toward the left, with one of the cop-retaining devices removed; Fig. 5, a transverse section of the ma chine shown in Fig. 1 on the line 5 5, looking toward the right; and Fig. 6, a section of the machine shown in Fig. 1 on the line 5 5, looking towardthe left.

Referring to the drawings, A represents a suitable table, foundation, or base to support the operative parts of the machine, the said table being represented as mounted upon a supporting stand or pedestal A, which may be of any suitable or desired construction. The table or base A in the present instance is shown as having erected upon it three transversely-arranged uprights A A A secured to the base, as by screws or bolts A uprights A A support in suitable bearings at their upper end two cop-shafts a a, (see Figs. 1, 2, and 5,) the said shafts at their front ends being made of reduced diameter to receive upon them cop tubes or cylinders a upon which the thread or other flexible cord is wound. The cop-shaft a, as herein shown, has fast upon it between the uprights A -A a gear a which meshes with a like gear a on the shaft a, and the cop-shaft ahas mounted upon ita normally loose pulley a constitutin g in the present instance the movable member of a clutch mechanism which cooperates with a disk or stationary member a, fast on the said shaft.

Thenormally loose pulley a is provided, as

herein shown, with a hub a which is loosely fitted upon the reduced portion of a sleeve a keyed on the cop-shaft a, and provided with an annular groove a", into which extends the end of a cam-shaped portion c0 of an arm a shown) by means of a belt, (not shown,) but which passes about the pulley a and the rotation of the cop-shaft 01, produces rotation of the cop-shaft a, but in an opposite direction. The cop-shafts a and a are adapted to have fitted upon their reduced end portions the cop tubes or cylinders a upon which the thread is The wound, and the said shafts have cooperatin g with them two thread-guides l) 1), herein shown as two uprights or arms, provided at their upper end with notches b and erected from plates b b movable in guideways in rotatable carriers, represented as plates orbars b I), (see Figs. 1, 2, and 4,) arranged substantially parallel with the axis of the shafts a a and secured to suitable frames revolubly mounted upon the bearings 2 for a camshaft b the said bearings projecting from the uprights A A The thread-guide carrier If is fastened at its opposite ends, as herein shown, to two cranks or arms I) b loosely mounted upon the bearings 2 3 on 0pposite sides of a cam-hub 11 provided with a suitable cam-groove I) for producing the desired reciprocation or traverse of the threadguides Z) Z). The thread-guide carrier Z) is also secured at its opposite ends, as herein shown, to two like cranks or arms I) 12 loosely mounted on the bearings 2 3, and the cranks or arms I) b of the thread-guide carrier b have extended from them, substantially at right angles thereto, arms 11 11 (see Figs. 2 and 4,) connected together, as herein shown, by a tie bar or rod 1), upon which is loosely mounted a depending rod (J23, extended down through the table or base A, as herein shown, and provided at its lower end with a weight I), which serves to keep the threadguide I) up in contact with the ball of thread as it is being formed.

The cranks or arms b 6 supporting the thread-guide carrier 1), have extended from them substantially at right angles thereto like arms 19 if", joined by a tie bar or rod Z1 upon which is loosely hung a rod b carrying a weight b The weights I) I) serve to keep the thread-guides b b in proper position with relation to the thread being wound upon the cop-tubes on the shafts a a, the thread-guides being gradually forced back awayfrom the cop-shaft as the ball is formed, thereby lifting the said weights. The earriers b b for the thread-guides are provided with suitable slots 6 of substantially the same length as the width of the cam-hub I), and the slide-plates b b are provided on their under side with suitable pins or projections, which extend into the cam-groove b, the said pins or projections being not herein shown, as they are well understood. The cam-shaft is driven from the cop-shaft a in a manner as will now be described.

The cop-shaft a at its rear end has fast upon it a pulley c, which is connected by a belt 0 to a pulley c revolubly mounted on a stud or shaft c on an arm a of a hub 0 provided with an arm c,extended, as shown, at an angle to the arm 0 and provided with a slot 0 (indicated by dotted lines in Fig. 3,) through which is extended a clamping screw or bolt 0 which is extended into the upright Aand serves to secure the pulley-carrying arm 0 in its adjusted or proper position. The hub of the pulley c is provided with a pinion 0 (see Figs. 2 and 6,) which meshes with a substantially large gear 0, fast on the cam-shaft b From this construction it will be seen that rotation of the cop-shaf t (4 produces rot-ation of the cam-shaftb by means of the pulley c, belt 0, pulley c pinion c and gear a. The supporting-arm c for the pulley-shaft c is adjustable in the are of a circle with the cam-shaft b as a center, so that the pulley 0 may be moved away from the pulley c in order to take up any slack in the belt 0. The pulleys c 0 preferably are slightly tapering in opposite directions, as shown in Fi 1 and 2, so that the speed of rotation of the camshaft b may be changed to regulate the rate of travel or reciprocation of the thread-guid es 1) 1) according to the size of thread to be wound upon the cop-tubes. To effect this change of speed, the belt 0 is movable over the pulleys, which is effected by means of a belt-shipping mechanism, herein shown as a forked arm (I, secured to or forming part of an internally-threaded collard, (see dotted lines, Fig. 1,) which is mounted upon a screwrod (1 having its inner end reduced in diameter to form a shoulder, and supported in upright A and a depending bracket cl, secured to the said upright, the shoulder on the screw-threaded rod (1 bearing against the bracket d when the screw-rod is turned to produce travel of the threaded collar (1 and of the shipper d. The inner end of the rod (1 is reduced again to form a second shoulder which bears against the upright A, and the said end is screw-threaded to be engaged by a lock-nut d countersunk into the upright, as indicated by dotted lines, Fig. 2. The shipper-arm d is guided in its travel by means of a guide-rod 01, attached to the bracket (1" and extended through the said shipper-arm. The machine herein shown is provided with an automatic stopping mechanism consisting of two connected members, either of which is adapted to effect the stopping of the machine, as will now be described. The carrier for the thread-guide b cooperates with one member of the automatic stopping mechanism, which member consists, as herein shown, of a hub or sleeve 6, (see Figs. 1, 5, and 6,) loosely mounted on a stud or pin 6, extended from the upright A the said hub or sleeve being provided at or near its opposite ends with two cranks or arms c e the crank or arm e.

being extended upward and provided with a horizontal extension carrying an adjustingscrew 6. The carrier for the thread-guide b has cooperating with it the other member of the automatic stop in echanism,which consists of a hub or sleeve a, (see Figs. 2, 5, and 6,) mounted 011 a stud or pin e projecting from the uprights A the said sleeve having at or near its opposite ends two upright cranks or arms a e, the crank or arm 6 having a substantially horizontal extension carrying an adjusting-screw 6 (See Fig. 2.) The cranks or arms 6 e on the sleeve e extend in substantially the same direction for a purpose as will be described. The crank or arm e is provided, as herein shown, with a notch 6 (see Fig. 6,) which is adapted to be engaged by a tooth or projection e on the hub or sleeve a, and the said hub or sleeve has fast to it one end of a spring e having its other end fastened to the upright A or to a stationarypart of the framework, the said spring being coiled so as to normally turn the sleeve or hub a in the direction indicated by the arrow 20 in Fig. 6, which movement on the part of the hub a would cause the cam portion a of the crank or arm a to move up into the groove a in the clutch hub or sleeve a and thereby move the said sleeve and the loose pulley a toward the right, viewing Fig. 1, against the action of the spring a, and thus withdraw the loose pulley a from the stationary disk or member a of the clutch on the shaft a. The hub a of what may be termed the starting mechanism for the clutch is provided, as herein shown, with an arm f, having a segmental brake-shoe f", which is adapted to beengaged with the sleeve a by the time the loose pulley has been disengaged from the stationary disk a so as to stop rotation of the cop shaft which is practically the main shaft for the machine herein shown. The spring e tends to move the hub or sleeve a in the direction indicated by arrow 20, Fig. 6, and when the machine is in operation, with the loose pulley a in engagement with the stationary disk I a the hub a is held from being turned by the spring 6 by the latch or projection e engaging the notch 6 in the crank or arm 6 (see Fig. 6,) which latter is held up in engagement with the said latch by a spring f connected to the crank or arm a and, as herein shown, to a screw f inserted into the sleeve 6.

In order that the single clutch mechanism may be automatically operated by either of the stopping devices, the crank e of one member of the automatic stopping device is connected to the crank or arm 6 of the other member bya linkf By this means it will be seen that when the crank or arm e is moved back by the carrier for the thread-guide b the crank e being extended substantially opposite to the crank or arm 6 will move in the opposite direction to the crank or arm 6 namely, in the direction indicated by the arrow 40, Fig. 6and by means of the link f will positively disengage the crank or arm 6 from the locking projection or latch e on the hub while if the crank or arm e of the other member of the automatic stopping 'mechanism is engaged by the carrier for the thread-guide I) both cranks e a will move in the same direction and the crank or arm a is moved directly backward in the direction indicated by arrow 40, so as to release the hub a and permit the spring e to disengage the loose pulley and at the same time apply the brake. The machine herein shown and described is simple in construction and is especially designed for high speed, and in practice the thread has been wound with the copshafts run at a very high speed-namely, thousands of revolutions to the minute.

On the machine herein shown balls of varying sizes may be wound at the same time, if so desired, by changing the position of the adj usting-screws e 6 so that one member of the automatic stopping mechanism may be operated upon when its ball has reached the desired diameter, which is less than that of the ball partially wound upon the other coptube, and after the finished ball has been taken off from its cop-shaft a new cop tube or cylinder may be placed on the cop-shaft and the machine again started to finish the ball partially wound and to commence winding a new ball on the shaft from which the finished ball has just been taken. I prefer to make the pulleys c c slightly tapering; but it is evident that the pulleys may be made of like diameter throughout, and such a machine could be used for one diameter of thread and would be useful on account of the increased output or production. The machine may be started by means of a handle 9, (see Fig. 6,) attached to the hub C613.

The cop-tubes a may and preferably will be held on the cop-shafts a a by means of the devices herein shown and each consisting of a sleeve g adapted to fit over the end of its cop-shaft and provided with a pin 9 on its inner side, (see Fig. 4,) which is adapted to engage a suitable cam or looking slot or groove 9 in the cop-shaft, the sleeve 9 being provided with a milled collar 9 I claim 1.
