To all whom it may concern.-

Be it known that I, JOHN OLIBHANT Mo- KEAN, a citizen of the United States, and a resident of Westfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Windmg- Machines, of which the following is a specification.

My invention relates to mechamsm more especially designed for winding yarn or thread in a cylindrical or conical form onto quills of cardboard or the like which have no heads and in which the thread mass is retained in shape upon the quill by laying the thread in long open spirals from one end to the other and back again, each thread laid in one direction crossing and binding down the threads previously laid in the opposite direction that is to say, the mechanism I describe is what is known as a quick-traverse machine for laying self-binding cops as distinguished from those mechanisms which lay successive spirals close together and which required a head upon the core on which the thread mass is built in order to retain the ends of the mass in position.

The object of my invention is to organize the parts of the machinery in such fashion that the length of thread between the surface of the cop and the thread-guide shall be very short and shall remain substantially uniform throughout the building of the cop at all sizes of the cop, and to provide, further, means which upon the breaking of the thread shall cause the cop to cease to rotate.

To this end the invention consists, essentially, in a driving-drum by means of which the thread mass and the spindle upon which it is mounted is rotated by the surface contact of the thread mass and the driving-drum,'the

. drum having an oblique or helical slot formed a in its periphery through which the yarn or thread passes and by which the thread is 4 moved-longitudinallyof'the thread mass on which the thread is ein wound. This slot may be formed of any esired shape to lay thread, as desired. If the slot is generated by rotating a cylindrical drum once and moving a point at auniform speed in contact with the drum one complete reciprocation while the drum is rotated once, the resulting slot will lay the thread in a uniform spiral on the cop. By increasing the pitch of the'slot at the ends or either end or in the middle the movement of the thread will be correspondingly increased, so that by varying the shape of the slot the resulting lay of the thread may be effected as desired. In laying conical-cops a conical driving-drum is employed and a correspondingly-shaped quill or tube, as is fully set forth in patent to Hill and Brown, No. 32,245, dated July 21, 1885,

and in building conical cops it is desirable to drum and its associated parts is a duplication of every other drum, I have shown only one drum and its associated parts in the drawings.

In the drawings, Figure 1 is a side elevation, partly in section, of a Winding-machine embodying my invention. Fig. 2 is a plan view of the drum and its associated parts. Fig. 3 is a detail, on a larger scale, of the angu-v lar lever G and its associated parts. Fig. 4 is a plan view of Fig. 3. spindle, showing the quill-retaining means.

, In the drawings, A is the main frame of the machine upon which are mounted and sus- Fig. 5 is a detail of the tained the movingparts. Adjustablysecured to a longitudinal member a is a swinging frame B, havingupwardly-projecting members Z) and b. The free end of the swinging frame B carries the shaft (1, upon which the drum D freelyrotates, the drum D being actuated by a belt from the power-shaft E, as will be plain. To the upper end of the projections 17 is secured a plate b ,'which is held almost in contact with the surface of the drum D. (See Fig. 1.) The drum D is formed in two parts, the opposed ends of which nearly touch, but leave a suitable space formin a slot (1 (See Fig. 2.) At the upper end 0 the member I) is mounted a swinging arm F, the inner end of which carries a spindle f, upon which is carried free to rotate the cop tube or quill. The quill is. retained upon the spindle by a hinged retainer f which is controlled by a knifeblade spring; so that it may be thrown out straight to receive the quill upon the spindle and then thrown up at a right angle to the 1 spindle, as shown in Fig. 5, to retain the uill upon the spindle. The arm is mounte on a rod f adjustable in a slot 1n the upper end of b, the portion of the rod within the slot being squared, and a handle b is provided by which the cop may be swung from-the surface of the drum D. The hub b of the arm F is split and clasps the rod f, and a screwthreaded bolt b passes through the two halves of the split hub and serves to give a frictional action to the hub 6 upon the rod f, which may be graduated at will, so that the movement of the quill away from the drum D as the cop grows may be had against any desired frictional resistance.

It is desirable that when the thread breaks or runs out in the winding process the machine should be stopped, and to this end I have provided a stop-motion. It will be seen, Fig. 1, that the arm B is supported by a toggle member consisting of an angular lever G and a link g. The lever G is carried by a bracket H, fast to a longitudinal member h of the frame. At the free end of the lever G is a swinging handle g, pivoted upon a transverse pin 9 carried at the free end of the lever G, and this handle has a projecting bar 9 extending to one side. On this pin g is also pivoted a drop-bar I. Upon the extreme outer end of the lever G is a stop g*, which limits the downward fall of the pivoted handle. The movements of the drop-bar are limited in one direction by a stop 71, which engages the bar 9, and in the other direction by a stop 9 on the lever G. The drop-bar carries at its outer end a hook i. In operative relationship with the hook i is an oscillating hook J, actuated by a connecting-rod and crank motion from the power-shaft of the machine. (See Fig. 1.) Supported on the member h beneath one end of the drum D is a brake K.

The mode of operation is as follows: As shown in Fig. 1, the machine is supposed to be in operation. The toggle members G 9 having been thrown into line, the drum D on the swinging frame B is raised from the brake K and the belt between the power-shaft and the drum D is tightened, causing the drum D to rotate in the direction of the arrow. The quill carried at the inner end of the frame F is pressed against the surface of the revolving drum. The thread is passed through the tension memberT into the slot on one side of the drum, through the drum, and out of the slot in the other side of the drum, one side of the thread against the edge of plate 5 the thread then passing to the quill. In passing from the tension member T to the drum the thread is hooked under the drop-bar I, holding the swinging hook i out of the path of the oscillating hook J. The rotation of the drum D coacting with the edge of the plate 1) causes the thread to be guided longitudinally of the quillfrom one end of the quill and back again, so that the slot in the drum and the plate I) form together a thread-guiding means forlaying the thread. This thread-guiding operation is, as shown in the patent to Hill and Brown, No. 332,951, dated July 21, 1885, upon which my present invention is an improvement. As the cop grows it is obvious that the quill upon which it is formed must be pressed away from the surface of the drum by the increment of thread, and this action is resisted to any desired extent by the braking action of the split hub f. The cop may be removed from the surface of the drum at any time, if desired, by depressing the handle I) of the frame F, which will swing the cop upward. It will be observed that the movement of the cop swinging upon the frame F is to the front of the ma'chinethat is, away from the frame. I11 the Hill and Brown patent above mentioned and in all other machines of the same ty )e the cop has been pivoted to swing toward the framethat is, toward the direction in' which the drum rotates and toward the plate, which served as one member of the thread-guiding means.

The effect of this was that as the cop grew in size and the qu ll swung upward the center of the cop moved over the thread-guide plate and caused the distance between the operative edge of the thread-guide plate and the point upon the surface of the cop where the thread seated itself to lengthen somewhat, so that at the end of the reciprocation of the thread thereon when the thread was reversed a loose loop of slack thread was formed which tended to throw out over the ends of the co and become broken or abraded, and the on s of the cop in consequence were imperfectly formed. It is obviously desirable in a selfbinding cop that the thread should be delivered upon the surface of the thread mass as closely as possible and placed and held in place where it is laid and that any play of the thread between the thread-guide and the surface of the cop is an undesirable feature where the thread is reversed in direction with great rapidity. which I have shown in the drawings is such that the swing of the cop as it grows is in a direction away from the operative edge of the thread-guide plate b", so that any increasing in length of the thread between the threadguide plate and the surface of the cop is counteracted by the movement of the center or quill of the cop in a direction opposite to what has commonly been practiced. The result of this organization of parts is that the length of the thread between the edge of the thread-guide plate and the surface of the cop is maintained practically uniform and as short as is practicable. When the thread breaks or when the thread runs out, owing to the exhaustion of the source of supply, the drop-bar I will be released and the hook i, will by gravity be moved into the path of the oscillating hook J. The drop-bar I being pivoted to the end of the lever G, the lever G will be immediately pulled down at the next The organization of parts ITO engages the stop 0'. on the drop-bar I and lifts the hook "2 out of the path of the hook J, and the thread thereafter sup orts the weight of the drop-bar I so long as tr e thread continues I l member inoperative relation with the toggle to ass under the drop-bar.

n the practical operation of a machine such as I have described it is-highIy desirable that when the machine is first put in operation the drop-bar be held up until any slack thread has been wound and the thread is in condition to su port the, dropbar, to the end that the dropar may not remain down with its hook in the path of the reciprocating member. To efiect this, the swingin handle g on the toggle member is provide with the laterally-extending bar 9 which engages with the stop 11 on the drop' bar and lifts the drop-bar and its hook when the toggle member is raised and set by means of the swinging handle. The handle is held momentarily after the to gle member isset, thus supportin the dropar until the thread is taut, and w en released the handle falls and is stopped by the stop g on the end of the angular lever G, leaving the drop-bar supported by the thread or yarn. It is obvious that by adjustment of the point of support of the swinging frame F the arc of movement of the qluill may be governed as desired.
