SPINNING-FRAME.

SPECIFICATION forming part of Letters Patent No. 722,145, dated March 3, 1903.

Application filed June 12. 1902.

To aZZ whom, it may concern:

Be it known that I, ALONZO E. RHOADES, a citizen of the United States, residing at Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Spinning-Frames, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

In United States Patent No. 686,906, dated November 19, 1901, an apparatus is shown and described whereby a spinning-frame is adapted to Wind the yarn upon a yarn receiver or bobbin in such manner that a preliminary winding or bunch is first laid and thereafter a main or service winding of yarn is laid, the yarn-receivers so wound being subsequently used in the shuttles of automatic filling-replenishing feeler-looms, a feeler acting to effect a change of filling when the yarn has been woven off down to the preliminary Winding and While there yet remains sufficient yarn to extend one or more times across the loom. Means are provided in said patent for regulating the position of the preliminary winding on the barrel of the yarn-receiver, for varying the length of traverse during the formation of such winding, and for varying the volume or amount of yarn therein. My present invention relates to the same type of apparatus as is disclosed in said patent; and it has for its object the production of various improvements in such apparatus, whereby more convenient adjustments may be made, and 1 have also made provision herein for adapting my invention to a somewhat different type of spinningframe, as will more clearly appear hereinafter.

In the patent referred to the ring-rail is raised by means of a lifting-weight and depressed by or through the builder-motion,

the drum thereof being gradually unwound to effect the gain of the traverse by letting off the chain little by little as the yarn is laid upon the yarn-receiver. Another type of spinning-frame, however, which is extensively used is provided with means whereby the lifting of the ring-rail is effected by the Serial No. 111,334. (No model.)

builder-motion, the descent of the rail being due to gravity, and in such apparatus the drum of the builder-motion gradually winds up the chain in order to effect the gain of the traverse, and my present invention is shown in connection with such latter type of spinning-frame.

Figure 1 is a front elevation of a portion of a spinning-frame showing the builder-motion and cooperating parts embodying my present invention, the preliminarywinding or bunch of yarn having been laid on the yarnreceivers or bobbins, the ring-rail being shown at the bottom of such preliminary winding and with theapparatusreadytobegin the main or service winding. Fig. 2 is a transverse sectional view on the line 2 2, Fig. 1, looking toward the left, the rocker-arm being omitted. Fig. 3 is an enlarged side elevation of a bobbin, showing the preliminary winding or bunch thereon completed, and the ring-rail at such time is at the lowest point of its traverse and ready to ascend to begin the main Winding with the full traverse, the ring being indicated in dotted lines. Fig. i is an enlarged front elevation of the carriage, its support, and the means for controlling the traverse to form the preliminary and the main windings, the parts corresponding in position to Figs. 1 and 2. Fig. 5 is a top or plan View thereof, also enlarged. Fig. 6 is a rear side elevation, partly broken out, of the mechanism shown in Fig. 4. Fig. 7 is a transverse section on the line 7 7, Fig. 6, looking toward the right. Fig. 8 is a detached detail in plan of the traverse-controlling means in the relative position shown in Fig. 5. Fig. Ois a top or plan view of the carriage detached. Fig. 10 is a side elevation of the locking-lever, to be hereinafter described, taken in connection with one member of the means for regulating the volume of the preliminary winding. Fig. 11 is a side elevation, detached, of the unlocking device. Fig. 12 is a similar View of the pawl-carrier and pawl forming a part of the means for regulating the volume of the preliminary winding. Fig. 13 is aside elevation of another member of said regulating means, by the adjustment of which isdetermined the extent of angular movement of the ratchet forming a part of said means; and Fig. 14 is a plan view of the traverse-controlling means for the preliminary winding, taken during such winding.

Referring to Figs. 1 and 2, the frame A, spindle-rail R on which are mounted rotatable sleeve-whirl spindles S, the verticallyreciprocating ring-rail R, provided with rings B, one for each spindle, the lifter-rods L, only one of which is shown, (see Fig. 1,) the rockers L each having a roll, as 3, for the foot of the lifter-rod, and a counterbalancingweight W, and the upturned rocker-arm L, rigidly connected with each rocker, may be and are all of well-known construction in spinning-frames, the arms L being connected by a link L to swing in unison, so that the power applied to one rocker will be transmitted to the other one, and thence through the lifter-rods to the ring-rail.

It is assumed that the rockers are mounted near opposite ends of the frame, and in the apparatus herein shown the descent of the ring-rail is eflected by gravity, and its ascent is accomplished positively by or through the builder-motion,and owing to the type of frame herein illustrated I have shown the buildermotion connected with the arm L of the rocker farthest therefrom. The builder-arm B fulcrumed on the frame at B, is provided with a follower b Fig. 2, to cooperate with an actuating or'traverse cam T, herein shown as heart-shaped, said builder-arm having mounted upon it the winding mechanism, in-

cluding a drum M, pick-shaft m, provided with a worm m to eifect gradual rotation of the drum, pick-wheel m on said shaft, and an actuating-pawl m operated in usual manner, the rotation of the cam rocking the builder-arm to effect through intervening connections the traverse of the ring-rail.

A weight 13 on the builder-arm counterbalances the weight of the winding mechanism and maintains the follower b in engagement with cam T.

From an inspection of Fig. 1 it will be manifest that each depression of the builder-arm will raise the ring-rail, and in order to effect the gain of the traverse, whereby at each upstroke the rail rises a little higher and at each downstroke descends not quite so low as on the previous stroke, laying the yarn upon the bobbin in successive layers from the lower end or base thereof upward, the chain O secured at one end on the drum M and indirectly connected with the ring-rail, must be gradually wound up. The chain O leads up over a sheave 5, rotatably mounted on the girder A of the main frame, and it-is adjustably connected, by means to be described, with a carriage G, mounted to slide longitudinally on a supporting-bar d, Figs. 5, 6, and 7, rigidly secured to ears d, secured to or forming part of a stand D, mounted on the girder A and having a horizontal guideway d parallel to the bar d to receive a fin e on a lateral extension cof the carriage, the bar and guideway constituting a track for the lat ter, substantially as in my patent referred to. The carriage has an offset 0, provided with an upturned stud c and with a horizontal lug or stop 0 for a purpose to be described, and an upright hub. c is made on the extension 0, and viewing Fig. 6 the carriage has at its right hand or outer end a depending portion 0 provided with a lateral fulcrum-stud e for the locking-lever E. in Fig. 10.) Alocking-pin e is pivotallycon nected at c with the locking-lever and upturned to slide loosely in the hub 0 the pin projecting a considerable distance above the top of said hub when in operative position, as in Fig. 7. ver E is the heavier to normally lift the locking-pin, and a follower-stud 6 projects laterally from said lever on the side nearest the stand D and at the heavier end ofthe lever.

An unlocking device (shown separately in Fig. 11) is herein shown as a compound lever E E both parts being fulcrumed at e on a depending apron d of the stand, the fulcrum-stud e passing through a longitudinal slot (1 Fig. 4, and being clamped in adjusted position by a nut a, substantially as in the patent referred to. The lever member E has pivoted upon it at e a switch 6 a cam-lug e on the member E being upwardly inclined from the pivoted end of the switch, the lower end of the cam-lug forming a stop-shoulder 9 to limit downward movement of the switch without interfering with its upward swing on its fulcrum,the structure being clearly shown in Fig. 11, and referring to Figs. 5 and 6 it will be seen that the switch and cam-lug are in the path of the follower-stud e and the apron d is provided on its inner face with an elongated stop d projecting beneath the switch.

In my prior patent the unlocking device E E is made as a single casting; but herein I have shown the members E E as separate and pivotally connected, the member E being forked or bifurcated at its fulcrum, as at a (see Fig. 5,) to receive between the forks or bifurcations the pivoted end of the member E, the latter having a toe e (see dotted lines, Figs. 5, 6, and 11) to project beneath a shoulder e on the member E The weighted end of the member E maintains the toe and shoulder in engagement and the parts in the relative position shown in Figs. 6 and 11, a projection 01 on the apron, Fig. 6, serving to limit the downward movement of the member E. Manifestly the member E? can be swung upwardly on its fulcrum e without moving the member E, and downward swing of said member E will be resisted or controlled by the weight of the member E.

The locking-lever E moves bodily with the carriage C, while the unlocking-lever E E is fulcrumed on a fixed stud e, and, referring to Fig. 6, if the carriage is moving toward the right the follower-stude will pass be- The opposite end 6 of the le-' (Shown separately heath the cam-lug e" and the switch e lifting the point of the latter and permitting it to drop into the position shown in Fig. 6 after the stud has passed, this operation being hereinafter referred to when describing the operation of the apparatus as a whole. The upright stud c at the back of the carriage is loosely extended through a hub f of one member F of the traverse-shifting means, (shown separately in Figs. 8 and 14,) said member F being made as a casting, having the hub at one end and an extension f at its opposite end, of reduced thickness, and at one side a depending stop f adapted to bring up against the nearest ear (1 should the connection between the controlling means and the rocker-arm L be released. Opposite to the stop f the side of the member F is recessed, as at f, to abut against the upper end of the locking-pin e when the parts are in the position shown in Figs. 4 to 7, inclusive. The bottom of the hub f rests on the flat top of the offset 0 of the carriage, as shown in Fig. 7, so that the member F may at times swing horizontally on the stud 0 so that the recess f may be moved into and out of alinement with the locking-pin.

The member F is provided with a longitudinal rib f on its upper face, embraced by a groove g (see Fig. 4) in the bottom of a slide member G, having a longitudinal slot g therein to receive a clamping-screw g, which enters a suitable threaded hole in the rib f so that by means of the clamping-screw the plate G can be held rigidly in adjusted position nearer or farther from the fulcrum c of the member F, a washer g being interposed between the head of the clamping-screw and the top of the member G.

A chain or other flexible connection C Fig. 1, is attached at one end to the rockerarm L, and at its other end it is connected with a hook g pivotally connected by a bolt g with an overhanging part g of the member G.

The hub f has an ear f at its outer side provided with a tapered hole f to receive the shank of a hook 20, which is attached to the adjacent end of the winding-chain O a collar 21 having a rounded end to abut against the concaved face f of the ear f surrounding the end of the shank, which latter is threaded, and set-nuts 22 are screwed onto the threaded end of the shank, as clearly shown in Figs. 5, 8, and 14.

By setting up or easing off the nuts the position of the preliminary winding or bunch on the filling-carrier will be changed, so that if the nuts are set up the ring-rail will be elevated and if the nuts are let off the ring-rail will be lowered slightly, thereby in the one case or the other positioning the bunch or preliminary winding higher up on the bobbin or lower down nearer its head.

In my prior patent the construction therein is such that an adjustment similar to that just described varied the amount of yarn in the preliminary winding, and in my present invention I have provided other means for varying the amount of yarn in such winding, and such means will be hereinafter described.

The rounding of the end of the nut 21 per mits the hook 20 to swing on the concaved portionf of the hub f as a fulcrum when the member F changes its position from that shown in Fig. 5 to the position shown in Fig. 14, or vice versa.

As the locking member E is mounted on the carriage,it will be manifest that when the locking-pin ex is raised above the top of the hub c the member F will be held or locked from movement to the right, viewing Fig. 5, relatively to the carriage; but if the lockingpin is depressed below the memberF thelatter can swing on its fulcrum c to the right, and during the formation of the preliminary winding the member F is unlocked and free to swing on its fulcrum c and it is automatically locked or held from swinging movement to the right, viewing Fig. 5, at the beginning of the main or service Winding, as will be more particularly referred to hereinafter.

Referring to Figs. 4 and 5,the stand D is provided with a vertical recess 24, and another vertical recess 23 is formed in a forward extension D on the stand,the recess 23 receiving a depressor, shown as a slide-bar 7L vertically movable in the recess 23 and beveled at its upper end at h, its lower end projecting below the stand and having a transverse slot k loosely entered by a stud h on a lever H, fulcrumed below the stand at h and having its outer end weighted, as at H. A similar slidebar is vertically movable in the recess 24, and its upper end is beveled at 7c, while a transverse slot at its lower end loosely receives a stud 70 on the leverH,the two arms of the lever H being offset one from the other, as shown in plan View, Fig. 5, and herein the slide-bars h and 7c are pivotally connected on opposite sides of the right-hand arm of said lever viewing Fig. 4. The free end of the lever is provided with an inturned toe 72/ which extends beneath the lower edge of the stand D and limits the upward movement of the slide-bars h and k. A latch it, having a notch 72, is fnlcrumed on the stand at h", the latch having a weighted offset h tending to swing the latch to the left against the end of a dog 71 (fnlcrumed on the stand at h during the time that the main winding of yarn is being laid upon the bobbin, such position of the parts being shown in Fig. 4. The dog 71 is provided with a depending tail 71 longitudinally slotted at 71 to receive loosely a pin it, extended laterally from the weighted end H of the lever H. The latch is upturned at the left of its fulcrum, viewing Fig. 4, to form a trip h, which extends above the stand D when the notch h and the dog 71 are in engagement, the trip at that time being in the path of the extension f of the member F, the lower face of such part sliding upon the top of the stand. A cam-wing 71 is extended from the trip for a purpose to be described.

The part fof the member F of the traverseregulating device extends across the stand D toward the front of the spinning-frame far enough to include in its longitudinal path of movement the upper beveled edge of the slide-bar it; but the slide-bar h is outside of or beyond such path of movement, as will be .manifest from an inspection of Fig. 5. 1 The upright face of the partfis rounded or convexed, as at f, to rock on the upright flat face of the slide-bar k as a fulcrum during the formation of the preliminary winding, as shown in Fig. 14..

Referring now to Figs. 6, 7, and 10, the carriage C is provided with a hanger 0 on which is rotatably mounted a ratchet TX, having a sleeve-like hub r and a reentrant or cut-away part 1', so that its toothed periphery is non-continuous. The stud 0 which is rigidly secured to the hanger 0 and on which the ratchet TX is mounted, also supports between the ratchet and the hanger the hub 19 of a pawl-carrier P, (shown separately in Fig. 12,) one end of the pawl-carrier having a beveled toe p and at its opposite end an enlargement or weight p, and on the end nearest the toe a pawl 19 is fulcrumed at p said pawl being shaped to present a tooth pflwhich overhangs and cooperates with the ratchet TX, and projections 19 on the pawl are arranged to cooperate, respectively, with pins and 66 on the carriage 0. That one of the ears (1 nearer the toe p of the pawl-carrier is provided with a longitudinally-slotted extension (Z (see Fig. 6,) in which is ad justably mounted a roll or other stud (Z to cooperate with the toe p and depress it when the carriage is moved to the left, viewing Fig. 6, to thereby lower the pawl into position to cause its tooth p to engage one of the teeth of the ratchet, and when the carriage O thereafter moves to the right, still viewing Fig. 6, the weighted end p of the pawlcarrier swings the latter to elevate the pawl and at the same time turn the ratchet through a space equal to one tooth, the continued upswinging of the pawl-carrier bringing it into position (shown in Fig. 6) with the projection 11 against the stop 66, the function of the pin 55 being to lift the pawl by engaging the projection 19 to thereby disengage it from the ratchet. Thus the ratchet will be turned through a small angular distance each time the carriage is moved to the left, Fig. 6, during the winding of the bunch, and the number of teeth through which the ratchet is turned by the means described regulates or controls the number of layers of yarn which will be laid upon the bobbin during the winding of the bunch.

In order to determine how far the ratchet shall be turned in the direction of the arrow 90, Figs. 6 and 10, I have mounted upon the hub r of the ratchet a stop-arm N, having an oppositely-extended and weighted end N, a

set-.screw N holding the stop-arm fixedly upon the ratchet-hub 7'.

Referring now to Fig. 6, if the ratchet were free to turn on the f ulcruin-stud 0 opposite to the arrow 90, (such movement being induced by the eccentrically-located weight N,) the stop-arm N would be swung up against the lateral projection c on the carriage, and such angular movement of the ratchet would carry the rentrant portion 1' thereof upward from the position shown in Figs. 6 and 10. Then when the carriage began its reciprocations the step-by-step rotation of the ratchet in the direction of the arrow 90,effected by or through the pawl 19 would continue until the ratchet arrived at the position shown in Figs. 6 and 10. Consequently a certain number of engagements of the pawl and ratchet must have taken place to turn the ratchet sufficiently to carry the stop-arm N from its upper position against the extension 0 down to the position shown in Fig. 6, and by loosening the set-screw N and changing the angular position of the arm N- relatively to the reentrant part 4 of the ratchet the latter would have to be turned a greater or a less angular distance before the ratchet would assume the position shown in Fig. 6that is to say, if the stoparm were adjusted at a greater distance from the extension than is shown in Fig. 6 it will be manifest that the ratchet would have to be turned a greater distance to bring it into the position shown, whereas if the stop-arm were adjusted nearer to the extension 0 than shown in the drawings a less rotative movement of the ratchet would be effected.

The locking-lever E has at its end adjacent the locking-pin 6 a depending segmental extension 6 provided at its lower end with a lateral projection or lug e constituting a detent and stop for the ratchet, said lug e acting as a stop when it can enter the reentrant part 1", as shown in the drawings, and acting as a detent during the angular movement of the ratchet to bring the rentrant portion thereof opposite to the projection 9 it being remembered that the tendency of the eccentric weight N is always to turn the ratchet opposite to the direction of the arrow 90, while the weight 10 of the pawl-carrier acts to turn the ratchet in the opposite direction, and in order that the pawl may turn the ratchet when it is in engagement therewith the weight 19 is heavier than N.

Referring now to Figs. 4, 5, 7, and 8, the partf of the member F is provided with an upright postf on which is fulcrumed at f a weighted pawlf, the lower end of the pawl being beveled, as at f Fig. 4, to correspond with the bevel h of the depressor, the latter being located in the path of movement of the pawl as the carriage O is traversed back and forth, the object of the pawl being to act upon the depressor h and move it downward to lock it into position, as will be described.

In Fig. 3 the bobbin or yarn-receiver is shown as of well-known construction and comprising a barrel at, having an enlarged head or base a, the cylindrical portion of the barrel near the head, and which is technically termed the feeler-wood, as at a indicating the portion of the barrel on which the preliminary winding or bunch of yarn is laid. It is desired to wind upon this bobbin a preliminary winding or bunch, as t, and thereafter to complete the winding by the main or service winding, (indicated by the dotted lines 17,) and the mechanism hereinafter described is constructed and arranged to automatically wind such bunch and thereafter to lay the main or service winding, both beinglaid with the filling-winding-Ahat is, the traverse is uniform during the winding of the bunch t, although it is shorter than the traverse with which the main winding 15' is laid, the gain of the traverse being provided for to lay the yarn in succeeding superposed layers around the bobbin.

The operation of the apparatus will now be described in detail, beginning with the starting of the main or service winding, inasmuch as the drawings show the parts in position to begin such winding.

Referring now,therefore, more particularly to Figs. 4, 5, and 6 in connection with Figs. 1 and 2, the preliminary winding or bunch I? has just been completed. The short traverse has been finished and the locking-pin e has risen through the hub 0 into the recess f of the member F of the traverse-shifting means, so that said member will move bodily with the carriage G, and the part f of the member F is behind the slide-bar h and adjacent and just to the left of the slide-bar 71;, Fig. 5. The weight of the ring-rail acting through the chain C and hook g upon the member F will hold such member pressed against the locking-pin 6*, as the lever-arm between the fulcrum c of the traverse-shifting means and the bolt 9 is greater than the distance between said fulcrum and the hook 20, attached to the chain O The traverse or actuating cam T rotates in the direction of the arrow 700, Fig. 2, and as it rotates from the position shown therein the builder-arm B will be swung downward and will act through the chain (3* to move the carriage G and the parts mounted thereupon to the left, Figs. 4 and 5, in the direction of the arrow 800, or to the right, viewing Fig. 6, and the rockers L will be swung up to elevate the ring-rail, the latter starting from the bottom of the bunch or preliminary winding and making its full traverse, effected by the cam T, to the upper end of and slightly above the bunch. As the carriage is moved on its first stroke in the direction of the arrow 800 the pawl f will ride over the upper beveled end of and depress the slide-bar 72., thereby tilting the lever H, raising its weighted end H, so that the pin 7r thereon will act through the tail of the dog h to depress the dog until the latch h swings over to bring the end of the dog and the notch 7L5 into engagement, and at that time both of the slide-bars 7t and 7; will be lowered below or flush with the top of the stand D and so retained while the dog and latch remain in engagement. The next stroke of the carriage C will be to the right, Figs. 4 and 5, and the full length of the long traverse, and its long stroke, communicated to the ringrail by intermediate connections, will effect the long traverse for laying yarn upon the bobbin in the formation of the main or service winding t, and the gain of the traverse during such winding is effected by the gradual winding up of the chain C on the drum of the winding mechanism carried by the builder arm. Such gain of the traverse causes the carriage C at each left hand stroke, viewing Figs. 4 and 5, to move a little farther toward the left and not quite so far to the right on each right-hand stroke, and just before the service-winding is completed this gradual advance of the carriage toward the left, Figs. 4 and 5, will bring the edge of the partf of the member F into contact with the trip it", rocking the latch h and withdrawing its notch from engagement with the dog 71. so that the lever H will by reason of its weighted end H swing up into the position shown in Fig. 4, elevating the slide-bars h and 7t, and very shortly after this movement of the slide-bars into the position shown the main winding will be completed.

In the apparatus herein shown, as is usual in spinning-frames, when a bobbin or set of bobbins has been filled it is necessary to wind back by hand, to thereby set the apparatus in readiness to begin the winding of a new set of bobbins, the winding back being effected by throwing out the pawl m and rotating the pick-wheel m in such a manner that the chain O will be unwound from the drum M. Remembering that at the completion of the main winding the carriage O and the parts carried thereby are nearer the left-hand end of the stand D, viewing Figs. 1, 4, and 5, the winding back (which is really an unwinding) will permit the carriage to move bodily to the right, and during such movement the pawl f will lift over and drop past the upturned end of the slide-bar 7t, and the rounded cornerf of the member F will bring up against the upturned vertical edge of the slide-bar 70, thereby assuming the position shown in Figs. 4 and 5. During the formation of the main winding with the long or full traverse the locking-pin e has remained in engagement with the member F of the traverse-shifting means, as has been described; but inasmuch as the locking-lever E travels with the carriage the stud e and the locking-lever will have been gradually moved toward the right, viewing Fig. 6, or to the left, Figs. t and 5, until the said stud has passedbeneath and beyond the point of the switch e permitting the latter to drop into the position shown in Figs. (5 and 11, so that when the resetting or winding back is effected the stud will contact with and ride over the upper face of the switch at or about the time that the pawl f lifts and drops over the slide -bar h. The act of Winding back carries the stud 6 onto the cam-lug e of the lever member E depressing the latter, and thereby raising the weighted member E until the stop (1 is encountered, bringing the member E to a stop, and then the continued movement of the carriage toward the right, Fig. 4:, or toward the left, Fig. 6, during winding backaots through the cam-lug e and the stud e to tilt the looking memberE to draw the locking-pin e down in front of the member F and below its under posite direction on the carriage through face. As soon as thelocking-pin is thus withdrawn the pull of the chain C will exert a greater influence on the traverse shifting means F and G than will the pull in the opthe chain O and the edge f of the member F will bear against the upright edge of the slide-bar k and act as a fulcrum to swing the rigidly-connected members F G on such fulcrum to move the carriage to the right, viewing Fig. 5, from the position shown therein to about the position shown in Fig. 14, (the limit permitted by winding back,)' the pin e moving bodily with the carriage, and the fulcrum edge f will remain in contact with the slidebar 70, the latter serving as the fulcrum for the connected members F G during the formation of the preliminary winding or bunch upon the bobbin, and the slide-bar will be designated as the fulcrum member. By referring to Fig. 14 it will be seen that when the parts are shown in that position the pawl f is diagonally across the beveled upper end of the slide bar h, and the latter will be slightly depressed, but not enough to lower the slide-bar 70 from engagement with the fulcrum edge f and no further depression of bar k can then take place, as the carriage O is at the limit of its movement to the right. The apparatus is now ready to begin the preliminary winding or bunch, and the rotation of the actuating-cam T acts to reciprocate the carriage C with the same stroke heretofore imparted to it; but at this time it will be noted that the members F G swing in unison on the fulcrum member 70, and inasmuch as the chain 0 is attached to the member G quite near the fulcrum edgef it will be manifest that the long stroke of the carriage will effect a very much shorter stroke for the ringrail, the length of the short stroke depending on the adjustment of the member G on the member F toward or from its fulcrum 0 The nearer the member G is set or adjusted toward the stud c the farther away it will be from the fulcrum member 70 and the longer will be the stroke of the ring-rail during the preliminary winding, and, conversely, the nearer the member G is set toward the fulcrum member 1a the shorter will be the ringrail stroke. The winding mechanism controls the gain of the traverse during the formation of the preliminary winding or bunch, as well as during the formation of the main winding, and therefore the carriage C will be gradually advanced toward the left, Figs. 1, 4, and 5, during the bunch formation, and this gradual'gain of the carriage acts to gradually bring the members F G and the carriage back again from the position shown in Fig. 14 to the relative position shown in Fig. 5, and when the locking-pin e is again lifted into locking position, as will be described, the stroke of the hook 9 will then be equal to the stroke of the carriage C, the parts then being ready to begin the formation of the main or service winding. The extreme right-hand position of the carriage at such time is shown in Figs. 4 and 5, due to the gain of the carriage to the left during bunch-winding.

Recurring for a moment to Fig. 6, which, it will be remembered, shows the parts in their position just after the finish of the preliminary winding, it will be seen that the detent e is in the rentrant portion r of the ratchet; but when the locking-pin is lowered by the travel of the stud 6 over the upper edge of the cam-lug e, as has been described, such rocking of the lever E Withdraws the detent from the reentrant portion of the ratchet, leaving thelatter free to be turned oppositely to the arrow 90, Fig. 6, by or through the eccentric weight N', until the stop-arm N engages the stop 0 of the carriage.

During the formation of the bunch it will be remembered that each movement of the carriage to the left, Fig. 6, operates through the action of the stud (Z upon the toep of the pawl-carrier to effect engagement of the pawl 19* with the ratchet, and as the carriage returns the ratchet is rotated through a space equal to one of its teeth, the detent e at such time clicking over its teeth and preventing retrograde rotation of the ratchet when the pawl is disengaged therefrom after each of its feed-strokes. At each stroke of the carriage from the left, Fig. 6, during bunchwinding the ratchet is advanced one tooth in the direction of the arrow until the reentrant portion r is brought opposite to the detent c the number of teeth through which the ratchet has been thus advanced depending upon the setting of the stop-arm N, as has been hereinbefore described, and immediately upon the positioning of the rentrant part of the ratchet opposite the detent the weight of the lever E will lift the end thereof, carrying the detent and the locking-pin into position shown in Fig. 6, terminating bunch-winding and positioning the parts for the immediate beginning of the main or service winding, as shown in Figs. 4 and 5.

' There will be as many layers of yarn laid upon the bobbin during the formation of the preliminary winding as teeth of the ratchet have been engaged by the pawl 13 a Very convenient and ready means for adjusting or regulating the amount of yarn to be laid in the bunch being thus provided.

As in my prior patent I employ herein but one actuating or traverse cam to impart a uniform stroke to the carriage, and I am euabled by or through the traverseshifting means to produce a short and adjustable traverse very much shorter than the traverse due to the shape of the cam 'l, and I also provide for automatically changing from short to long traverse,thelattercorrespondingto the stroke of the carriage C and due to the shape of the actuating-cam. The traverse-shifting means herein shown is capable of very fine adjustment, as it will be manifest that the change of position of the member G upon the member F can be not only readily effected, but with great accuracy and delicacy.

The means for determining the amount of yarn to be wound in the preliminary winding or hunch is totally different from the means shown in my prior patent and is capable of a greater range of adjustment and greater ac curacy.

Notwithstanding the fact that in my present invention the resetting of the carriage involves an unwinding of the chain O from the drum M, I have retained the term winding back, as that is the technical term employed for so manipulating the winding mechanism carried by the builder-motion that the frame shall be set in condition for beginning the Winding of a set of bobbins.

\Vhen the carriage is retrograded by the winding back, the right-hand edge of the part f of the member B will engage the upper edge of the cam-wing it should the latch be accidentally set, and will thereby depress the trip it out of the way to prevent any injury to the parts.
