JOHN DEMPSTER WHYTE, OF URMSTON, ENGLAND.

YARN-WINDING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 605,984, dated June 21 189 8. Application filed September 22, 1397. Serial'No. 652,580. (No model.) Patentedin England October 5,1896,No. 21,992.

a subject of the Queen of Great Britain, re

siding at Urmston, near Manchester, Lancaster county, England, have invented certain new and useful Improvements in Yarn-Winding Machinery, of which the following is a specification, the invention having been patented in England, No. 21,992, October 5, 1896.

My invention relates to improvements in yarn-winding machinery used for cross-winding yarn into cops, as is now well known, and it relates particularly to improvements in an apparatus for which I have obtained Le'tters Patent in the United States, No. 586,279, of July 13, 1897.

As already stated in my former patent, No. 586,279, of July 13, 1897, under my invention I am enabled to wind successfully upon the bare spindle without the use of the usual guide-cups or substitutesvtherefor, and also to produce cops for warping or other purposes the contents of which would be ordinarily wound upon bobbins.

According to my present invention the essential features of my former invention are retained; but I have devised various improvements in detail which are adapted to produce a more perfect and effective apparatus. As

before, the spindle is carried vertically in a suitable carriage, and the same is lowered as the winding on proceeds. A cone-shaped cam is again employed to operate the yarnsheets of drawings.

On Sheet 1, Figure 1 is a sectional view of my improved apparatus. Fig. 1 is a plan View of the curved guiding-plate over which the yarn passes to the yarn-guide. Fig. 2 is a front elevation. On Sheet 2, Fig. 3 is a plan view of the driving-disk and frictional driving-pulley. Fig. tis a plan View of the conecam and yarn-guide. Fig. 5 is a plan View of the yarn-guide andthe bracket carrying the same. Fig. 6 shows the contour of the copping-plate. Fig. 7 is a diagrammatic View showing the method of oscillating the rockshaft used to effect the stoppage of the apparatus on the breakage of the yarn. Fig. 8 represents a side elevation of the cone-cam. Fig. 9 is an end elevation of the cone-cam. On Sheet 3, Fig. 10 is a detail View showing more clearly the stop-motion for eifecting the stoppage of i the apparatus on the breakage of the yarn. Fig. 11 is an edge view of a portion of the parts shown in Fig. 10. Fig. 12 is an end View of the pivoted bracket carrying the friction driving-pulley- Fig. 13 indicates a modified method of actuating the yarnguide. Fig. l-iis an end view of Fig. 13. Fig. 15 is a further-modified method of actuating the yarn-guide. Fig. 16 is an end view of In the following description and drawings one spindle and its accompanying parts only are referred to 5 but it will be understood that a frame maybe provided with any convenient number of spindles.

The spindle a is secured to the revolving sheath a, which sheath is adapted to revolve in bearings formed inthe sliding supports a The supports a are adapted to slide on rods a A frictional pulley b, driven from the disk 0,

motion by suitable reducing-gear,as indicated in myformer United States patent,No. 586,279, of July 13, 1897, operates the descent of the spindle as the winding proceeds in the following manner: Upon the shaft b, on which the pulley Z) is mounted, is a grooved pulley cl, to which is secured a cord 61', carrying a weight (1 Upon the end of the shaft b is mounted a plain pulley (1 to which is secured one end of a cord (1 the other end of the cord being attached to the upper support a of the spindle-carriage. To the lower support a of the spindle-carriage is secured another cord 6, passing over a pulley e, mounted in hearings in the bracket f. The cord e carries a counterbalance-weight e When the spindle-carriage is in its highest position, as indicated in the drawings, the cord d is wound to some mounted on the shaft 0, which receives a slow extent upon the pulley (Z. By the revolution of the shaft 1) the cord (1' is unwound from the pulley (Z, the cord d" being wound upon the plain pulley (Z thus pulling down the spindle-carriage as the winding of the cop proceeds. The pull of the weight (I is counterbalanced by the counterbalance-weight e which exerts a pull upon the spindle-carriage in a direction contrary to that exerted by the weight (1 The spindle-carriage is thus co unterbalanced or held inequilibrium and its downward traverse arrested immediately the friction-pulley I) is moved out of contact with the driving-disk c.

The method of adjusting the friction-pulley b upon the shaft 1) to vary the speed of downward traverse of the spindle-carriage is clearly shown in the plan view Fig- 3. The pulley b is slidably mounted upon the revolving shaft b by means of a slip-feather and groove or the like, so that while revolving with the shaft it is capable of being slid along the same. A fork f engages with the boss of the pulley b, the other end of the fork being formed as a nut engaging with a screw f By operating the screw f by means of the projecting nut f the pulley b may be traversed along the shaft Z). i

The spindle a is driven by means of an endless cord g, passing partly around a grooved pulley g, mounted on the spindle of the conical building-cam 7L, and from thence under two pulleys h, mounted to revolve in bearings in the bracket f, to a sliding wharve 1' upon the spindle-sheath a. The wharve is slidably mounted on the spindlesheath a by means of a slip-feather and groove, so that while the sheath is driven it is enabled to slide within the boss of the wharve 2'.

Instead of moving the driving-disk c away from the friction-pulley b on the breakage of the yarn, as. in my former invention, I move the pulley Z) from contact with the drivingdisk. This is effected in the following manner: Upon the driving-shaftj I mounta bandpulleyj, whereby motion. is communicated by means of a band or beltj to the pulley g, mounted on the spindle of the conical cam h.

The pulley g is formed double to accommo pendent lever 79, pivoted on the axis of the conical cam h, carries, adjustably secured to it, a pulley 712'. \Vhen in the position shown in Fig. 1 and in full lines in the detail View Fig. 10, the pulley 7o maintains the beltj taut, so as to drive the pulley g and with it the conical cam 72-. A double lever Z, loosely pivoted to the bracket Z, is connected by a link Z to a lever on.

The upper end'of the lever m carries an antifriction-bowl m, upon which rests the pendent lever 70. The lower end of the lever on. isloosely pivoted upon a stud m secured to the bracket f, and isformed with an extension m carrying at its lower end a bowl 771. A drop lever or finger n is mounted to turn upon a pivot n, secured to the lever m. P The end of the drop-lever n projects through a slot in the plate of, secured to the frame of the apparatus and bears against the under side of the drop-wire 0. The end of the droplever n is preferably bent at a right angle at the point where it is brought to bear beneath the drop-wire o, as shown in Fig. 1. The drop-wire o is pivoted at o to the bent plate or guide 19 and is maintained in its raised position (shown in Fig. 1) by means of the yarn 2). On the breakage of the yarn the dropwire 0 falls, depressing the drop-lever n and thus bringing an abutment n on the lever n in the path of a stud 19*, carried by a finger 29 secured to a rock-shaft p. The drop-linger n is thus pulled forward, drawing with it the lever m into the position shown in dotted lines in the detail view Fig. 10, thus allowing the pendent lever 71; to drop and slackening the driving-bandj which thus ceases to drive the pulley g and with it the cone-cam h. The band-pulleyj is made double and is utilized to drive a corresponding pulley g on the rear side of the frame. a

The method of reciprocating the shafts p is indicated in the diagrammatic view Fig. 7. Upon the driving'shaftj is mounted a spurwheel (1, gearing with a spur-pinion q, revolving in suitable bearin gs. Connecting-rods (1 mounted loosely on a stud g fixed on the pinion g, are loosely secured to cranks q. Consequently the continued revolution of the pinion q oscillates the cranks which aresecured to the ends of the shafts 1). The vibrating movement thus imparted to these shafts is communicated to the attached fingers p mounted on the shafts The diagram represents the arrangement in duplicate where spindles are mounted at each side of the windin g-frame. To stop the revolution of the friction-pulley Z) simultaneously with the cone'cam 71, on the breakage of the yarn, I mount the bracket 0, carrying the friction-pulley to rock upon a pivot '1", as shown most clearly in the detail view Fig. 12. A springr maintains the pulley Z) into frictional driving contact with the driving-disk c dur ing the working of the apparatus. I form an incline 0' upon the bracket 7, against which bears the bowl on, carried by the extension 072 of the lever on. This incline and bowl will be most clearly seen in the plan view Fig. 3. When in the position shown in dotted lines in Fig. 10, the bowl 771; traverses the incline '1', thus turning the bracket 9- upon its pivot 0" in the direction of the arrow,Fig. 12. The friction-pulley Z) is thus withdrawn from contact with the driving-disk c, and the downward traverse of the spindle is arrested. The driving-disk may therefore be utilized to actuate two spindle-carriages, one at each side of the apparatus, as indicated in Fig.1, the pinion b operating the spindle-carriage in the rear. hen piecing up has been effected, the attendant bypulling down the lever m by means of the handle returns the parts to their normal positions. The pulley 7c on the pendent lever again tightens the belt 7' while the spring 1' returns the pivoted bracket into its working position, thus again bringing the friction-pulley 1) into driving-contact with the disk 0. Y

The yarn-guide s is pivoted at s to a finger 8 secured to a spindle 8 which can turn freely in a bracket t,-bolted to the top rail of the apparatus.

A bowl 8 upon the yarn-guide s rests upon the cone-cam 7t and is maintained in contact with the cam by means of a spring i, secured at one end to the yarn-guide and at the other to an extension of the finger .9 as clearly shown in Fig. 1. the yarn-guide is arranged to be traversed from the smaller end of the cone-cam h to its larger end, so as to vary the traverse of the yarn-guide from a minimum to a maximum traverse at the commencement of the build of the cop. This is effected in the following manner:

Upon the spindle 5 to which the finger 5 carrying the yarn-guide, is secured, I key a bell-cranklever it. The upper end of the bellcrank lever u is connected to a spring to, the tendency of which is to turn the spindle 5 upon its axis in the bracket 2i, and thus traverse the bowl 3 along the conical cam h. will be more plainly seen from an inspection of Fig. 2. The lower end of the bell-crank lever u is provided with a finger 11. The upper support a of the spindle-carriage car-- ries a copping-plate o. This copping-plate is shown separately in Fig. 6. At the commencement of the build of the cop, when the parts are in the position shown. in Figs. 1 and 2, the finger n rests against the edge of the copping-plate and is maintained in 'contact therewith by the pull of the spring to. On the descent of the copping-plate o the finger n follows the contour of the edge of the plate, and the spindle s is thereby gradually turned on its axis, thus traversing the bowl 5 on the yarn-guide s from the smaller to the larger diameter of the cone-cam h, canting the finger 5 carrying the yarn-guide s, and increasing the traverse of the yarnguide. \Vhen-the maximum traverse has been attained and the cop-bottom formed, a snug 8 upon the finger 5 comes in contact with a screwed stopt carried by the bracket t, and is maintained in this position throughout the downward traverse of the spindle-carriage by the pull of the spring u. Figs. tand 5 show the snug s and screwed stop 27 more clearly, Fig. 4 being a plan view of the parts with the top rail removed, while Fig. 5 is a plan view of the bracket tand the finger to which the yarn-guide is pivoted. It will be evident that by operating the screwed stop 29* the traverse of the bowl 8 upon the yarn-guide 8 may be regulated so as to vary the maximum traverse of the yarn-guide 5. By pivoting the yarnguide 3 to the finger 8 as illustrated in Fig. 1, the requisite length of traverse of the yarn-guide As in my former invention,

Thiseye may be obtained with a smaller cone-cam it than is the case with the fixed yarn-guide illustrated in my former United States Patent,-No. 586,279. Figs. 8 and 9 illustrate, respectively, in side and end views the conecam h; The cam is formed with a quick-drop ridge, (shown in in dotted lines,) so as to provide for a rapid descent of the yarn-guide from the nose of the cop at the moment of reversal, so as to prevent an overwound or soft peak to the nose. It considered desirable, however, this drop-ridge may be dispensed with. The yarn passes from the cops (not shown in the drawings) through the tension device'w. (See Fig. 1.) The tension device 11) consists of two barrels covered with felt or the like and fixed to a bracket carried on a rod extending throughout the length of the frame. The bracket is loosely mounted on the'rod and secured thereto by a wingnut. By altering the angle of the bracket the tension on the yarn may be varied. WVhen winding from the hank, the tension device w may be dispensed with. From the tension device to the yarn is led over-the curved plate 19 to the eye of the drop-wire 0 and from thence through a slot in the plate 19 to the eye of the yarnguide 3. This is clearly shown in the plan. view Fig. 1- of the plate 19. When winding on the base of the cop, the yarn is conducted straightfrom the eye of the drop-wire 0 di-l rect to the cop, but when raised to the top of the cop-nose by the yarn-guide s it is directed against the under side of the curved portion p of the plate 19, which thus serves to put an increased tension on the yarn as it is being wound upon the thinner portion of the cop-nose. g V

Modified methods of obtaining the requisite traverse of the yarn-guide are indicated in Figs. 13 to 16, Sheet 3, of the drawings. In Figs. 13 and 14 the pulley g is provided with an eccentrically-mounted pin x, upon which the yarn-guide s rests and is oscillated by the revolution of the pulley g. Instead of the pin-0c an eccentrically-mounted angle-plate y may be employed, as indicated in Figs. 15 and 16. Inthe example illustrated by Figs. 13 and 142 the length of traverse of the yarngnide s is not varied; but in Figs. 15 and 16 the yarn-guide may be traversed from the smaller to the larger end of the anglefplate y when forming the copbottom, so as to gradually lengthen the traverse of the yarn-guide as the cop-bottom is being formed. Thus the example indicated in Figs. 15 and 16 may be used for the winding of the larger cops, While the modification shown in Figs. 13 and 14; is

suitable for the smaller weft-cops for which 7 a flattened bottom is not essential.

In winding yarn upon the bare spindle the cone-shaped cam or its equivalent is driven so as to impart a rapid vibratory movement to the yarn-guide, thus producing cross-wound cops. By reducing the speed of the cam a slow vibratory movement maybe given to the yarn-guide,if desired,so that instead of cross- IIO winding the yarn may be-wound in closelypitched superimposed spiral layers. In the latter case it would be necessary, however, to wind the yarn upon paper tubes or bobbins.

What I claim as my invention is 1. In combination in a yarn-winding apparatus, a movable frame, a spindle carried thereby, a cord and winding-drum, said cord being connected to the movable frame, a friction-pulley connected to said cord-winding drum, a weight acting to raise the frame and a weight acting in opposition thereto to hold the frame in equilibrium, and the drivingdisk for engaging the friction-pulley, substantially as described.
