YARN-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 586,279, dated July 13, 1897. Application filed October 24, 1896. Serial No. 609,961. (No model.)

To all wwnt it' may conceive:

Be it known that LJoHN DEMPSTER WHYTE,

engineer, a subject of the Queen of Great Britain and Ireland, and a resident of Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in YarnVinding Machinery, of which the following" is a specification. lily said invention relates to improved apparatus for winding yarn, and has for its object to widen the scope of usefulness of such machinery an d to improve the quality of the work turned out thereby. For example, under my invention I am enabled to Wind successfully upon the bare spindle and also to produce large cops for warping and other purposes, the contents of which would ordinarily be wound upon bobbins.

The improvements will be best understood by a detailed description of the annexedtwo sheets of drawings.

Figure 1, Sheet l, is a side elevation of a spindle carrying a warp-cop in the act of being wound, the adjacent parts which effect and regulate the winding being shown in conjunction with the said spindle. Fig. 2 is a plan of two of the automatic stop-levers. Fig. 3 shows a modification of the mode of operating the yarn-guide. Fig. 4, Sheet 2, is a plan view of the combination of parts shown in Fig. 1. Fig. 5 is a detached plan of one of the spindle-carriers. Fig. 6 is a back view of the building-cam and pivoted stock appearing in Figs. 1 and 4. Fig. 7 is a separate view of the slotted plate which inclines the stock. Figs. 8, 9, l0, and 11 illustrate cop-buildin g motions more especially adapted to the winding of the smaller weftcops. Fig. l2 is a view at right angles to Fig. 1, showing, however, only the spindle, spindle-carrier, canted stock, cam-cone, and the slow-motion gearing.

It will be understood that although in the following description I will refer to one spindle and its accompanying parts, nevertheless it must be understood that a frame may be fitted with any convenient number of such spindles and parts.

To begin with, I lower the spindles as the winding-on proceeds, and to admit of this each spindle a is independently carried in bearings in supports Z) b', the said supports being braced together by a rack-bar c, extending between the supports. The supports b b are formedin plan, as most plainly shown in Fig. 5, and slide on rods d d, extending between fixed rails e e', bolted to the end frames of the machine. .Vith the aforesaid rack-ba-r c there gears a toothed pinion c, carried on one end of a shaft e', the said 6o shaft being supported in bearings e2 e2 from the bracket e3, bolted to the fixed rail or beam The inner end of the shaft e' is furnished with a friction-pulley e4, as shown in dotted lines, capable of adjustment on the shaft e', so as to be set nearer to or farther from the center of the disk g. The friction-pulley e4 rests in frictional Contact with the disk g, which is one of a series of similar disks carried on a shaft g', extending throughout the length of the winding-frame. The said shaft g is caused to revolve slowly by woringearing driven from the roller-shaft t. The said slow-motion gear is as follows: A fast 75 pulley l0 is mounted upon the shaft 7L and driven by means of a belt from any suitable source. Upon the boss 11 of the fast pulley is mounted a spur-wheel l2, by which motion is communicated to the spur-wheel 13, car- Sa ried in adjustable bearings by the bracket 14, which is secured to the frame of the machine.

VThe spur-wheel 13 gears with the spur-whee1 15, thus driving the shaft 16 and worm 17. The worm 17 drives a worm-wheel 1S, which 85 is mounted on a stud 19, carried in a bracket 20. Connected to the worin-wheel 18 is a worm 2l, gearing with the worm-wheel 22, fixed upon the disk-shaft g. The pulley 23 is loose upon the shaft and provides for the 9o stoppage of the winding-frame. The spur- Wheels 13 and 15 can be removed and replaced with spur-wheels of varying sizes, thus allowing for the shaft g being driven at varying speeds. The disk g is secured to its shaft g 95 by a slip-feather and groove. The boss of the disk g has a groove g3, with which engages a pin z" on a horizontal lever fi, pivoted at ft2 upon the iixed beam f. This lever and its functions will be hereinafter referred to.` Ico The weight of the supports b b' and the spindle and other objects carried thereby is counterbalanced bya weight j, the cord or chain j of which passes over a grooved brakepulley 7c, carried on a stud projecting from the fixed beam f.

Vhen the machine is in operation, the toothed pinion e, engaging with the rack c, is slowly and continuously revolved by the friction al driving effects of the disk g on the friction-pulley el in such a direction as to lower the spindle gradually as the winding of the cop proceeds. The spindle ct is driven by a band Z from the roller h or-its equivalent,

the band passing partly around the barrell a" of the spindle, or it mightbe a sliding wharve, thence beneath a guide-pulley e4, carried by the bracket e3, thence over a pulley m', carried on the upper end of a lever m, pivoted at m2 upon a projection from the fixed rail f, thence to the pulley n, which drives the spindle of the building-cam n, and so back to the roller h'. The lower end of the pivoted lever m acts so as at times to shift the disk g on its4 shaft clear of the friction-pulley e4 and also so as to operate a brake-lever 0, pivoted at o to the bracket e5. The head o2 of the brake-lever is formed of a crescent shape to it over a portion of the periphery of the pulley 75, over which the counterbalance-weight cord passes. The lever m also carries, loosely pivoted thereto, a drop lever or finger p, having an eye at its outer end through which the yarn q passes on its way to the cop. The finger p is thus upheld clear of a revolving or reciprocating cam r, which lies opposite to a notch or recess in the finger p.

Should the yarn accidentally break, the tinger p drops, and the cam catching in the notch pushes the iinger forward and thus pulls forward the pivoted lever m against the resistance of a springing, which connects the upper end of the lever to a xed bar m4. The throwing forward of the lever and the pulley m slackens the band Z,which thus ceases to drive. At thesame time the lower end of the lever m releases the heel of the brake-lever o, which falls partly by its own weight and partly by the pull of a spring 03, which brings the crescent braking-head o2 down upon the pulley /t' and holds it firmly. This prevents the spindle and cop from dropping or moving after the breakage of the yarn, audit is very essential that this should be done; otherwise inequalities would arise in the cop.

It will be noted by an inspection of Fig.2 that the operated end of the lever 1l is formed with a slot i3, the said slot being-straight at first and then inclined. This is for the following reason: It will be clear that before relieving the friction-pulley e4 from contact with the disk g it is necessary to apply the brakelever o. Therefore during the movement of the lever m which releases the brake o the tailof the lever mis passing along the straight portion of the slot 712, and therefore does not move the lever fi; but as soon as the brake has descended on and gripped the pulley 7o, thus preventing all perpendicular movement of the spindle, the tail of the lever m enters and moves along the inclined portion of the slot 713, thereby turning the levert' on its pivot and moving the disk g along the shaft g suh'- ciently to di'sengage it from t-he friction-pulley e4. The parts are returned by the attendant to their normal position when piecing-up has been effected.

To effect the building of a cop--say, forexample, a large warp-cop, such as the cop q, (shown in Fig. 1,) with a iiattened or only slightly-rounded bottom- I provide ymeans whereby the movement of the yarn-guide s commences when the cop is starting to be built with a minimum traverse and gradually increases while the bottom is being formed to a maximum traverse, with which traverse the main body of the cop is built and finished. This is brought about by the arrangements of mechanism hereinafter described. This general action is the same as that referred to in my English patent, No. 13,863, dated September 26, 1888, and in my United States patent, No. 458,927, dated September 1, 1891.

For the purposes of my invention I employ a cone-shaped cam n, which is best seen in Fig. 6 of the drawings, this cam being mounted on the spindle which carries the bandpulley n', the cam being thus revolved. The smaller end of the cone-shaped camA represents the minimum traverse or throw of theV yarn-guide s. The larger end represents the maximum traverse. Upon the cam there rests the lower end of a sliding jack t, the said jack t carrying the yarn-guide s. This guide s has an eye s' opposite tothe spindle a, and when the cone u is used is prolonged to present another eye s2 in proximity to the cone u.'

This cone u might be dispensed with, and its purpose when used is to regulate the taking up of slack of yarn from the creels, if such' slack should arise. The cone u is carried in a loose pivot-bearin g u at the foot of the cone,- as shown in Fig. 1, the cone being of the same slope as the angle of the top of Vthe cop, but

'inverted relatively thereto, the small end of the cone being opposite to the base of the `copnose, while the larger. end of the cone is opposite to the peak of he cop-hose.

The function of the cone u is to provide for a constant delivery of the yarn from the creels from which it is wound and thus prevent sagging and jerking of the yarn. Then yarn is wound upon a cop without the use of the cone u, it is evident that, as the speed of the spindle is constant, more yarn is woundupon the base or thickest portion of the cone of the cop than upon the apex or thinnest portion of the cone. Thus the yarn gradually sags or becomes slack as the yarn-guide approaches the apex of the cop. .To prevent this sagging 0I the yarn and maintain it taut, v.the yarn. is

first passed around the inverted cone u and through the eye s2 of the yarn-guide, and from thence to the eye s. The yarn, therefore, as it is being' wound upon the base of the copnose passes around the lower part of the inverted cone a. As the yarn-guide raises the yarn toward the apex of the cop, the yarn is also correspondingly guided up the inverted cone, thus taking up the slack of the yarn. The cone u, representing the same cone as the nose of the cop, but inverted, acts as a compensating means to keep the yarn taut, taking vup little yarn when the yarn is being Wound upon the thickest portion of the cop, but gradually taking up more yarn as the yarn-guide rises to the apex Of the cop.

The aforesaid sliding jack t slides in bearings t" t" on the stock c, the said stock being loosely pivoted at u2 upon a bracket w, bolted to the fixed rail e. When the cop is being commenced, the pivoted stock and jack @t are about perpendicular, as indicated, for example, in dotted lines in Fig. 6, a frictionboWl at the foot of the jack resting on the smaller end of the conical cam n. Vhen the winding on commences, the smaller end of the conical cam reciprocates the jack t only slightly, the spindle a at the same time beginning to be lowered by the action of the toothed pinion e on the rack c.

The top support b of the spindle carries a plate with an inclined slot, as plainly shown in Fig. 7, the inclined slot being occupied at the commencement of the building of the cop by a pin ifprojecting from the back of the pivoted stock. As the slotted plate descends with the lowered spindle-support b the influence of the slot acting on the pin moves the lower end of the pivoted stock to one sidethat is,to\vard the larger end of the conical cam n. The longer this side movement of thejack or stock is continued the larger becomes the traverse of the yarn-guide s, the guide both rising and lowering a little more at each traverse, which, cooperating with the simultaneous lowering of the spindle, produces the required iiattened bottom t0 the cop. Vhen the stock o has rbeen so far moved that the jack t rests on the larger end of the cam n, as is shown in full lines in Fig. 0, the plate leaves the pin on the stock, and at the same time to keep the stock in its angular position a jawed locking-clip y falls over by its own Weight and secures the stock in its inclined position, the building of the cop then proceeding under the maximum traverse until completion.

An advantage derived from the throwing of the stock tf into the angular position is that as the Winding on proceeds the yarn-guide s is traversed at the same angle as the nose of the cop, the guide thus lying close to the cop as the building proceeds. The cam n is preferably made with a quick-drop ridge or step 1n its circumference, as plainly shown in Fig. l, so as to move the yarn-guide s quickly away from the nose of the cop at the moment of reversal and so prevent an over-Wound or soft peak to the nose.

I do not confine myself to the conical cam n as a means of obtaining the building traverse of the yarn-guide. I might, for instance, in place of the described cam, jack, and stock use the inclined or wabbling disk I. (Shown in Fig. 3.) Here I employ a pivoted lever 2, carrying on its free end an arm 3, to a prolongation of Which the yarnguide s is attached. A strut 4 is mounted on the arm 3, the said strut sliding on a square rod 5 and engaging with a collar 6, carried on a screw 7, held in the arm 3. A prolongation of the shaft which carries the cam-disk l is tted with a fixed arm 8, which sweeps over the collar 6 as the cam revolves and by advancing the collar on the screw at the same time advances the strut from the center toward the outer circumference of the disk l.

The fixed arm Sis made long enough to operate the collar and strut during the building of the bottomof the cop. When the collar 6 has moved out of the range of the fixed arm 8, the maximum traverse has been attained and goes on till the cop is completed.

The arc vibrated through by the outer end or eye of the yarn-guide s is approximate to the inclination of the cop-nose. (See, forexample, Fig. 8.) Fig. S also shows a form of grooved disk-cam 9, which might be used to give the traverse to the yarn-guide s. In this example, which, together with the remaining examples of traversing mechanism, is intended to be applied more especially in the Winding of the smallerWeft-cops, there is no attempt to vary the traverse at the commencement of the cop, a attened bottom to such smaller cops not being an essential.

In Fig. 9 the disk-cam l used is similar to the cam shown in Fig. 3 and acts in the same manner, except that there is no attempt made to vary the traverse, as in Fig. 3, the maximum traverse being preserved from first to last. In this Wabbling cam-disk l there is a ledge or step, as more plainly shown at Fig. l0, to give the desired quick reverse at the peak of the cop-nose.

In Fig. ll I make use of a crank instead of 'a cam to give the required oscillationto the yarn-guide. Here also there is no attempt to vary the traverse. My improved method of Winding confers advantages both in warping and Weaving with cops so Wound. For example, in warping-frames the absence of the usual bulky bobbins economizes space, and, the yarn being drawn either from the interior or the exterior of the cops, the latter may IOO IIO

be placed on closely-pitched cop tongues or spindles or into holders ,mounted closely together on uprghts or on a frame, the noses or ends of the cops being toward the warp mill-reeds. y
