WINDING-MACHINE.

SPECIFICATION forming part of Letters Patent NO. 572,309, dated December 1, 1896.

Application filed October 11, 1895. Serial No. 565,314. (No model.)

To all whom it may concern:

Be it known that 1, ALFRED B. MORSE, of Easton, county of Bristol, State of Massachusetts, have invented an Improvement in finding-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide an improved machine for winding thread, string, yarns, and the like onto cops, cones, or other equivalent or well-known forms.

My invention 00 niprehends a rotatable spindle upon which the quill, cone, or other core which is to receive the yarn or string ,is mounted to swing about an axis, and athreadguide also preferably mounted to swing about and means to move this movable thread-guide in such manner as to cause it to maintain a substantially fixed line of travel relatively to the swinging spindle.

Myinvention comprehends a novel variable tension for the string or yarn and other features which with the foregoing will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a front elevation of a machine illustrating one embodiment of myinvention; Fig. 2,a top or plan View of the machine, Fig. 1; Fig. 3, a partial rear side view of Fig. 1; Fig. 4, a detail showing the manner of gearing the thread-guide cam tion adapted for winding-cones; and Fig. 11,

the shafts a a l have mounted, respectively, the oppositely-facing cones or cone-pulleys a a, connectedby a belt a under the control of a shipper a, fast on a shipper-rod a", mounted at the rear end of the machine in a suitable bearing in the standard aat that side of the machine and at its front end (see Fig. 8) threaded to engage the interiorlythreaded adjusting-nut a journaled in the front standard a. Rotation of the thumb-nut a causes axial movement of the shipper-rod a and travel of the shipper to move the belt 0? along its cones for varying the relative speed of the two shafts.

The winding-spindle Z) is journaled in the forked free end of a swinging support or lever Z), (see Fig. 1,) loosely journaled on a sleeve surrounding tlre projecting front end of the shaft a, and is extended at the opposite side of the said shaft (0' to sustain the counterweight b At its rear end the spindle 1), between the two arms of the forked end of the lever Z), has fast upon it a gearwheel 11 in mesh with a gear-wheel b loosely mounted upon a spindle b carried by the lever 11, said wheel in turn meshing with a gearwheel 1), fast on the main shaft a of the machine, rotation of said main shaft causing corresponding rotation of the winding-spindle.

The winding-spindle and its lever-like support I) may be swung into any desired position about the main driving-shaft a without in any way interfering with the rotation of the spindle from said shaft, the intermediate idler-wheel b always following and being in mesh with the two wheels at its opposite sides. The thread-guide 0, shown as an eye formed in a finger c on the end of a slide-bar c mounted to slide in suitable guideways in the top or cross bar 0 rigidly connected with the two carrying-arms c fulcrumed at c on the base. These supporting-arms have journaled in them a shaft 0 fast on which between the said supports is a path-cam 0",which acts upon a roller or other stud c on and to reciprocate the bar 0 and its thread-guide 0.

Mounted loosely upon a boss on the rear support a, surrounding the shaft 0 is an eccentric c, the strap 0 of which is provided with an arm c, in the end of which is journaled a stud 0 fast on the end of an arm 0 of a strap 0, surrounding an eccentric 0 loosely j ournaled on a boss of the rear standard a, surrounding the shaft (L The shaft a is provided with a change-pinion d, which meshes with and drives a toothed wheel 01, loosely mounted on the stud c, and which in turn meshes with and drives a toothed wheel (Z fast on and to rotate the camshaft 0 This connection between the shaft a and the cam-shaft 0, whereby the latter is driven from the former, is such as to permit the supports 0 carrying the thread-guide, to be swung about their fulcrum c to carry the line of travel of the thread-guide into any de sired position without in anyway disturbing the driving connections.

By adjustment of the eccentrics c and 0 the stud 0 on which the idler-wheel d is mounted, may be drawn toward or moved from either the pinion d or the wheel d for fine adjustments, or for making changes in the gearing, if desired.

One of the supports 0 (see Fig. 1) is pro vided with an L-shaped arm (1 the upturned end of which is engaged by a roller or other suitable stud d on the lever-support Z1, carrying the Winding-spindle.

A weight (1 adj ustably mounted on an arm (Z on one of the supports 0 acts to hold the said arm (1 always in operative contact with the said roller-stud (Z The thread, yarn, string, twine, or what ever it is desired should be wound into cop, cone, or other form by the machine is taken from a suitable source and is led, as shown at w, Fig. 1, over a suitable pulleyf, thence under a second pulley f, thence up and over a grooved tension-wheelf down and about a pulley f thence through a pigtail guide f about and through the guide 0 to the quill, cone, or other core mounted upon the spindle.

The tension-wheel f is fast on a short arbor f loosely mounted in a forked arm a on the front support a of the frame, and near the inner end of this short arbor f and'between the arms of the forked support is made fast a grooved pulley f (Shown best in Figs. 2 and 5.)

Loosely mounted upon a sleeve bearing frame surrounding the arbor f is a sleeve f provided with an arm f connected by a rod f with the weighted end of the lever-support b, said sleeve being also provided with a segment-like arm f to which is connected one end of a cord or strap f which rests inthe groove of the pulley f and sustains at its lower end one or more Weights f the latter acting to keep the cord or strap f in frictional contact with the bottom of the groove of the said pulley f to exert more or less retarding effect upon and to resist rotation of the arbor f and its tension-wheelf about which the thread, yarn, &c. is passed to the windingarbor. v

The operation of the machine is as follows, viz: The quill, cone, or other suitable core Q, upon which the thread, &c., is to be wound,

is suitably secured to and upon the windingspindle b and the machine set in operation. Rotation of the main driving-shaft a acts, through the gears b b and 11 to rotate the winding-spindle in the direction of the arrow, Fig. 1, to wind the thread upon the quill or cone carried by the spindle. The drivingshaft 01, also acts, through the belt 0. and the cone-pulleys, to rotate the shaft a which, through the gearing shown in Fig. 4, also rotates the cam 0 which in turn reciprocates the thread-guide c, causing it to traverse the length of the quill or cone and lay the thread thereupon in manner well understood by those skilled in the art. As the cop or body of thread builds up in thickness upon its core the winding-spindle b will be depressed, its supporting-lever b turning about its fulcrum a, the weight b however, keeping the surface of the body of thread always in contact with the under side of the thread-guide. It is essential in winding-machines of this class that the thread guide maintain a substantially constant position with relation to the body of thread being built up upon the cone, and this desired uniformity of position is preserved in the present instance by the roller 01 on the lever b, which as the lever is depressed by the building up of the body of thread acts, through the L-shaped arm 01 to draw the fulcrumed supports 0 to the right, Fig. 1, against the action of the weight 01 to carry the line of travel of the thread-guide to the right, Fig. 1, thus maintaining it always in substantially vertical position over the mid dle of the body of thread upon the spindle. As the body of thread upon the core or spindle builds up it is desirable for the best results that the tension be gradually reduced to compensate for the greater diameter of the body of thread and the more rapid travel of the thread, which of itself acts in the nature of a tension. This is provided for in my improved machine by the rod f", which as the body of thread is built up and depressed, as described, is raised by the raising of the weighted end of the lever Z), and when so raised acts (see Fig. 5) to rotate the segment f to the left in the direction of the arrow, Fig. 5, to carry the point of attachment of the friction cord or strap f farther down on the periphery of the grooved wheel f and as the said friction cord or belt always hangs straight, by reason of the weights suspended thereupon, it is clear that the farther the point of attachment is moved toward a horizontal line passing through the axis of the tension-wheel arbor the less the length of the cord or strap which remains in frictional contact with the said grooved wheel. Consequently as the body of thread is depressed the weighted end of the lever b is raised and the segment turned down to gradually reduce the frictional action of the cordor strap f 11 on the grooved pulley, and thereby lessen the tension thus put upon the thread. This is an important feature of my invention, for it enables me to obtain a uniformity of productwhich is impossible with an unvarying tens1on.

By means of the weights f and 5 which, in fact, act in opposition to each other, one counterbalancing to a greater or less extent the other, a very nice adjustment may be had, which is valuable in winding high grade threads, twine, &c.

Referring now to Fig. 2, upon the drivingshaft a back of the front standard a are the fast and loose driving-pulleys h and h, the belt-shipper for the same being shown at 71;, fast on a sliding shaft 71?, mounted in suitable bearings in the standards a a. Parallel with the shipper-shaft 7L3 and also mounted in the supports a a is a second shaft h provided near the rear standard with an arm 71 which overreaches the shaft h and lies in the line of travel of a lug 77, on the said shipper-shaft 71 A spring 7L7, interposed between the front standard h and the said arm 7L5, acts to press the shaft 77. rearwardly. At its outer end in front of the front standard a the shaft 71, is

notched to receive one end of a lever h fulcrumed at 71 and provided with a set-screw 72, adapted to be engaged bythe weighted end of the lever-support b as the latter is raised by the building up of the body of thread on the core.

Assuming the driving-belt to be upon the loose pulley h, the machine is started by drawing the shipper-shaft h toward the front of the machine, a suitable knob h thereon being provided for engagement by the operator, such forward movement of the said shipper-shaft also through its lug 7L6 and the arm 72 causing a similar forward movement of the shaft h, and when the latter has reached the limit of its forward movement the lever h acted upon by the weightof the set-screw h drops, into the notch 71, referred to, and holds the said shaft 72, in its forward position. \Vhen the body of thread hasbeen built up to the desired diameter, determined by the adjustment of the screw h the rising weighted end of the lever b engages said set-screw and lifts the latter, thereby disengaging the lever 77, from the notch in the rod 72,4 and 'permittin g its spring 71, to throw the said rod and also the shipper-rod into their rearmost positions carrying the driving-belt from the fast onto the loose pulley and stopping the machine.

If it is desired to temporarily stop the machine before the body of thread has been built up to the final size, the operator may push inwardly the shipper-shaft and stop the machine without interfering with the automatic stop mechanism described, and he may thereafter again draw forward the shipper-shaft to start the machine without disturbing the automatic stop-shaft 71 leaving the latter in readiness to automatically stop the machine when the full size of the body of thread has been reached.

A stop-screw m, threaded in a lug m on the front standard a, acts to limit the upward movement of the winding-spindle, keeping the latter always at a proper desired distance from the thread-guide c.

The quill, cone, or core upon which the thread is to be wound maybe mounted upon and secured to the winding-spindle in any suitable or desired manner. In the present embodiment of my invention, however, (see Fig. 6,) I have provided the spindle adjacent its supporting-lever with a conical or tapering-shoulder n, and at its front end the said spindle is provided with a cam-groove n for the reception of a pin a on the clampingsleeve niprovided not only with a slightlytapering shoulder n opposed to the shoulder '12, but also preferably with one or more pointed projections n.

The quill Q,'(shown in Fig. 6,) or it may be a cone or other core,-is slipped upon the spindle and the clamping sleeve applied and turned, the pin n? in the cam-groove 41 acting to force the said sleeve inwardly to wedge the quill upon the tapering shoulders 11 and 02 and at the same time impress the projections n into the end of the quill to insure rotation of the quill or core by and with the spindle.

By means of the shipper-rod a the belt a may be shifted on its cone-pulleys, and the relative speed of the winding-spindle and the cam and thread-guide actuated thereby may be varied for different sizes of thread or yarn.

Referring to Fig. 7, it is desirable that the lever-support b for the winding-spindle be always accurately positioned, and to provide for the take up of wear I have threaded the end of the bearing-sleeve to receive a checknut 0, which may be screwed up as little as desired to take up wear and hold the lever support in proper position, a set-screw 0 furnishing means by which to lock said nut in its adjusted position.

Referring now to Figs. 9 and 10, the winding-spindle is mounted on an angle, so that the cone-shaped core q shall be rotated with its upper side coincident with a plane parallel with the base or parallel with the line of travel of the thread-guide c, as it is necessary that the thread-guide always travel in contact or parallel with the surface of the body of the thread on the core. In this modified construction the winding-spindle is provided with a gear q, similar to the construction Figs. 1 and 2, which gear meshes with an idler g attached to which is a skew-gear 91 which meshes with and is driven by the gear b Fig. 3. By this construction the spindle standing at an angle is suitably driven from the mechanism, Fig. 1. r

I show means to cause the thread-guide to too travel obliquely to the path of the same, as shown in Fig. 1, so that it shall be parallel to the conical surface of the core g, as desired. In this construction the support g for the traveling thread-guide is turned downwardly at an angle, as shown, and the thread-guide g traveling in the angular part of the support, is connected by a suitable link or flexible member g with a portion (f, carrying the stud g driven by the cam.
