FESTUS S. RAND, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO UNIVERSAL WINDING COMPANY, OF PORTLAND, MAINE, A CORPORATION OF MAINE.

WINDING-IVIACI-IINE.

Application led April 24, 1912.

To all whom it may concern:

Be it known that I, Fns'rUs S. RAND, a citizen of 'the United States, residing at Providence, 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.

My invention relates to winding machines and particularly to machines for winding cops or bobbins in which the yarn or thread is built up in conical layers to form a cylindrical body portion terminating in a tapered nose or delivery end.

My improvement consists in providing means for guiding and directing the threadguide in its traverse along the windingspindle to so regulate its path of travel that it will follow the inclination of the surface on which the yarn is being wound, in close proximity thereto, but without contacting with, or bearing on, said surface.

The object of my improvement is to prevent the thread-guide from rubbing against the layers of yarn as the latter are deposited on the cop, thereby relieving the yarn of the abrasive action to which it is usually subjected and preventing the guide from displacing the coils of winding after they have once been laid in place.

My improved device also provides for winding the yarn in steeper layers, that is, with a greater inclination to the axis of the cop than has heretofore been possible, because there will be less tendency of the coils to become misplaced and the nose of the cop to be broken down under the action of the guide; and hence more material can be compacted in a cop having a deiinite diameter and length.

The invention is fully set fo-rth in the following specification, illustrated by the accompanying drawings, in which Figure l is a longitudinal elevation of a portion of a winding machine, showing the winding-spindle and traverse-mechanism for the thread-guide, with the frame shown in section to illustrate the means for driving the spindle and guide; Fig. 2, a plan view of the windingspindle and traverse-mechanism; Fig. 3, an enlarged part-sectional view of the same, taken on the line A-A of Fig. 2, looking in the direction indicated by the arrow a; Fig. 4, an enlarged detail view of the guiding-devices for the thread-guide;

Referring to Figs. l and 2, B designates .the frame of the winding machine, in which s a bearing b for the rotating winding spindie C and a bearing b for the reciprocating traverse-bar D. The spindle C is driven from the main driving-shaft E of the machine through suitable connections, such` for instance, as the spiral or skew-gears e', c, shown in Fig. l; and the traverse-bar D is reciprocated by a rocker-arm j' mounted on the oscillating shaft F and connected to the traverse-bar by a link f. rlhe traverse-bar D is preferably constructed in two parts, with the main portion CZ arranged to slide in the quill-shaped bearing b; and the extension cl secured at d2 to the outer end of the portion CZ and supported at its opposite end in an outboard bearing H. The bearing H is mounted on a bracket H secured to the main frame B of the machine and extending parallel to the winding-spindle. An elongated bore 71, is provided in the bearing H and at its inner end is a bushing L in which the end of the extension cl of the bar D slides.

Mounted on the extension d of the traverse-bar D and arranged to oscillate aboutits axis is the traverse thread-guide G. Preferably, the main portion g of the threadguide, or the guide-holder as it is usually called, is constructed of sheet-metal in bifurcated form, with two legs g', g having upturned ears g2, g2. The ears g2, g2 are bored to receive bushings g3, g3 which surround the round rod or bar d and constitute bearings for the guide-holder g on the bar. Referring to Figs. 2 and 3, the opposite end of the guide-holder is formed with a curved opening or mouth g4 which leads into an eye g5 secured in an ear g, see Fig. 3, bent down from the main portion of the holder. Also secured in the guide-holder g, adjacent the eye g5, is the main button-shaped guide gt, formed with a V-shaped opening g8 through which the yarn y draws as it leads to the cop Y.

Between the legs g, g of the guide-holder g is an internally-threaded sleeve or nut Ze, arranged with its ends abutting the inner ends of the bushings g3, g3. As will be seen from reference to Fig. 2, the bar cl is formed with screw-threads (Z3 which are cut only partially around it, that is to say, through- "deposited on its surface.

out only one-half of its circumference. The threaded bore of the nut Z; is of sufficient internal diameter to allow it to slide freely over the threads Z3 on the bar CZ when the nut and bar are in axial alinement; but the threads in the bore of thenut maybe engaged with those on the bar by carrying the nut into a position eccentric to the axis of the bar. This is accomplished automatically by a spring Z fastened to the guide-holder at Z with its end Z2 bearing on the periphery of a flange L secured to the nut 7c, see Fig. 2. A contact-wheel or disk K is secured to the nut /3 adjacent the flange 7s and is adapted to bear on the periphery of the cop to receive an intermittent rotation therefrom which is transmitted to the nut Za to turn the latter on the traverse-bar. rlhe turning of the nut ZJ on the traverse-bar D acts to advance the thread-guide G progressively along the winning-spindle to effect the longitudinal growth of the cop, in a manner now well known to those versed in the art to which the present invention belongs.

The winding is started at the base end of the cop and the first layers of yarn are deposited on the conical butt or form of the wooden bobbin X, represented by dot-anddash lines in Figs. l and 2. In the machines previously employed for winding cops of the kind hereinbefore described it has been the usual practice to arrange the guide to bear directly on the surface of the winding as the coils of yarn are deposited in place. It has always been considered necessary that the guide should be in close contact with the cop in order that the coils of yarn may be disposed precisely and accurately as they are I have now determined, however, that the winding can be performed with the same accuracy and precision if the guide does not bear directly on the surface of the cop, providing it is maintained in close proximity thereto. In fact, the character of the winding is improved under these latterconditions, since the coils when once laid in position will not be subsequently displaced by the rubbing action of the guide. To accomplish my purpose of maintaining` the guide in close proximity to the surface of the winding during its traverse without allowing it to contact with the cop I make use of the devices now described:

Mounted in bearings 7b2, 7b3 in the bracket H is a rod M extending parallel to the traverse-bar D. This rod serves, in connection with certain other devices, to control the starting and stopping of the machine.y but as the stopping-mechanism is not related to the present invention it will not be described in detail. Pivoted on the rod M, at either end, are two hinge-members a and n which support a longitudinal bar N of square section extending parallel to the traverse-bar D.

' The members n and a preferably take the form of sheet-metal strips having their ends curled over at n2, n2 to surround the rod M, and their opposite ends are secured to the bar N by any suitable means, such, for instance, as the screws n3, a2, etc., see Figs. l, 2 and 3. Mounted to slide on the bar N is the track or guiding-plate P which controls and directs the course of the threadguide. As shown in Fig. 5, the plate P is formed of sheet-metal, substantially triangular in shape, with two ears 0, y) bent to conform to the shape of the bar N on which the plate is supported. Extending along the upper edge of the plate P is a slot p, formed by cutting away the metal which is bent back in a lip 292 to serve as a bearing face or track for the, guide-holder, as more fully explained hereinafter.

Attached to the under side of the leg g of the thread-guide holder g is a linger O having an offset portion 0 which extends through the slot ya and bears on the track 02. rlhe ringer O acts as a runner for the guide-holder g and travels in the slot 22 to direct the course of the thread-guide in conformity to the track p2 on the guide-plate P.

Extending from the arm ZL* of t-he bearing H is a lug 7i?, see Figs. 1 and 3. The lug Zr is positioned directly beneath the hingemember a and a stud R extends up through the lug with its end bearing against the nnder side of the member a. By turning t-he stud .l the hinge-member n can be adjusted upward or downward to raise or lower the bar N, and a check-nut 1 is provided on the stud to lock the latter in its adjusted posit-ion.

The operation of the whole device is as follows: Referring to Fig. 3, it will be observed that the thread-guide holder g is arranged to swing on the traverse-bar D to adapt it to oscillate toward and away from the winding-spindle C. The guide-holder g is arranged below the spindle C, this being opposite to the usual arrangement in previous machines, so that the movement of the guide away from the spindle is downward instead of upward. The yarn y is led up from its source of supply, not here shown, draws through the eye g5 and guide gl, and thence feeds on to the surface of the cop, which is illustrated in'Fig. 3 by the dot-anddash line Y. The cop rotates in the direction indicated by the arrow e and the tension on the yarn 1/ tends to draw the whole thread-guide Gr downward, away from the winding-spindle. This downward pressure of the guide is resisted by. the linger O which bears on the track p2 ot the plate P and the relation of the guide g7 to the surface of the oop is adjusted by regulating the position of the plate. Now, since the plate 13 rides on the bar N it is only necessary to raise or lower the latter to adjust the guide in relation to the winding, and this is accomplished by simply turning the stud R which bears on the hinge-member a. As shown in Fig. 8, the guide gT is set to just clear the outer surface of the cop Y when the finger (l is in the position illustrated in Fig. 4, and the tension of the yarn drawing through the guide will hold it away from the cop and maintain the finger O bearing on the track 792. As the traverse-bar D is reciprocated the thread-gide Gr is traversed back and forth along the winding-spindle C and the nger O will ride up and down the incline of the track p2. This causes the guide 97 to oscillate toward and away from the winding-spindle and the inclination of the track is such as to direct the guide in a path conforming to the tapered surface of the butt as of the cop-tube or bobbin X. In this way all of the layers of winding are laid on the cop-tube with the same inclinationto the axis of the cop while, at the same time, the thread-guide is kept from rubbing against the yarn during the whole winding. After the first layer of winding is built upon the butt x the periphery o-f the contact-wheel K will engage the yarn at its point of greatest diameter, during the backward stroke of the thread-guide, and the wheel will be turned to impart a slight, rotary movement to the nut 7c. In this way the thread-guide G is advanced a short distance along the traverse-bar at each reciprocation, or after each layer of winding is completed, so that the cop grows by longitudinal extension without any increase in the diameter of its body portion. Each advance of the thread-guide serves to slide the plate I) along its supporting-bar N to a corresponding extent, the finger O on the thread-guide holder g contacting with the end 2f* of the slot p in the plate to push the latter forward. `It will be seen, therefore, that the guiding-plate P keeps pace with the thread-guide in the latters advance along the winding-spindle and is constantly in posit-ion to direct the course of the guide so that the latter will follow the surface on which the winding is being performed, but without bearing on or rubbing against the yarn in the cop.

es befo-re explained, my invention provides a simple and efficient means for controlling the path of the thread-guide to maintain the latter in close proximity to the surface on which the winding is being performed, so that the coils of yarn may be laid in place accurately and precisely, while, at the same time, the guide is prevented from rubbing on the yarn. The yarn is therefore saved from rubbing friction and abrasion and the cop can be built up with steeper layers without any tendency for its nose to become soft or malformed through the displacement of the coils.

Various modifications might be made in the form and arrangement of the parts of my device without departing from the spirit or scope of the invention.
