ing is a specification.

This invention relates. to ringspinning frames, and has for its principal object to provide an improved means whereby a much may be'wound on the cop or 'quil for use in feeler-looms where the loom is stopped or an empty quill thrown out and a new quill inserted by the action of a feeler-finger which bears against the quill.

In looms of this class it is desirable to retain sufficient thread on the quill or cop to make one or two shots after the fecler has moved to operative position in order to avoid a thin place in the cloth. To accom plish this, a so-called bunch" is Wound on the cop or quill at the beginning of the winding operation, the bunch being usually arranged near the base of the cop at apoint beyond the lane of movement of the feeler-linger, this unch containing several yards of thread, so that two or more shots may be-made after thefeeler assumes operative position;

The principal ob ect of the invention is to so arrange and construct a ring-spinning frame that the bunch may be readily'formed at the proper point, and after a sulhcient quantity of thread has, been wound to form the bunch the traverse mechanism is automatically adjusted to permit-the ordinary winding.

A furtheriobject of the invention is to provide an attachment which may be applied to existing spinning-frames for this purpose.

A still further ObJGCl/Of the invention is to provide for the iMiJLlSill'IlBIlt of the traverse mechanism,so thatthering-rail may be lowered to the proper positlon to form a bunch.

\Vith these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hcrein after fully described, illustrated in the ac coinpanymg drawings, and particularly pointed out in the appended claimsfiit being understood that various changes in the form,

proportions, size, and minor details of the structure may be made without departing.-

from the spirit or sacrificing; any of the advantages ol'the invention.

,In the accon'ipanying drawings, Figure 1 is an elevation, partly in section, of a portion of a spinning-frame arranged and constructed 'in accordance-With the invention. Fig. a detail perspective view of the lm-ver portion of the mechanism, showing particularly the construction and mounting of the builderarm and the means for automatically shifting the builder-arm roller from engagement with the buncher-eam into engagement with the builder-cam. Fig. 3 is a sectional elevation of the mechanism for taking up the slack and traversechain to adjust the ring-rail to the lowest position for the formation of the bunch. Fig. 4 is a plan View of the mechanism shown in Fig. 3.

- Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In the, drawings, A represents the end frame, and B thespindleaail, of an ordinary form of spinning-frame The ring-rail C is operated in the usual manner through lifterrods D and the traverse mechanism, which includes the usual chain E, the lower endof the chainbeing connectedto a builder-arm 10, that is fulcrumed'on a stud i 1, carried by the frame.

In the frame of the machine is supported a cam-shaft 12, carrying a builder-cam 15 of the ordinary construction, this cam serving to depress the buildenarm 10 for the purpose I of operating the traverse mechanism. In the present instance the builder-cam carries a bunchcr-cam 16, which in the present instance is in the form of a disk, the pcripliicry of which is divided into a plurality of cams 16, each designed to impart slight vertical movei'nent to the builder-arm it) for the purpose of moving" the ring' rail in a vertical path during the winding of the bunch, the lift oi each cam being such thatthe .ringerail travcrses from top to bottom of the bunch at each movement, and the bunch. is tl'iercfore formed of crossed threads, which present a relatively hard surface on which the main winding may take place without danger of the yarn being pressed between or caught by the yarn forming the bunch, thus avoiding the breakage of the yarn, which frequently occurs where the hunch is formed of simple nncrosscd turns. i

The buildcuarm 10 is provided with a transverselydisposed opening carrying a .stud 17,011 the outer end of which is mounted an antifriction-roller' 18, which is arranged to be operated u on by the launcher-cam 16 until the bunch is formed and then is automatically shifted to be operated upon by the 'builder-cam 15 during the fhrther' and ordinary winding of the cop or quill. In order to facilitate the transfer of the roller 18 from one cam to the other, it will be noted that the deepest indentations between the projecmove the lever in such manneras to force the roller 18 from engagement with the bunchercam into engagement with the builder-cam. This movement, however, is resisted or prevented by a lo'cking mechanism which holds the lever 19 until the bunch has been wound and then releases it, allowing the spring to act and the roller to move into engagement with the builder-cam to complete the regular winding of the cop orquill.

At the outer end of the builder-arm is ar ranged the usual mechanism for gradually taking up the traverse-chain in building the cop; but this mechanism requires for its operation the full stroke of the builder-arm, and the limited stroke imparted by the bunchercam is not sufiicient to bring it into play, so that the traverse-chain is not taken u until after the bunch is formed and the ro ler 18 passes under the control of the builder-cam 'liigidly secured to the hub or collar of the builder-arm is a locking-bar 22, carrying one or more guides 23 for the reception of a longitudinally-movable bar 24, the outer end of which is pivotally connected to the lever 19. l The inner end of the bar 24 has an outwardly-- extended arm 26, and from the inner face of 7 this arm extend yoke-like guides 27, in which a vertically-movable rack 28 is mounted, the position of theirack at the starting of opcrations being determined by a pin 30, which may be placed in an one of a number of openings 31, that are ormed in the rack, the pin then resting on top of-the upper guide 27. The rear face of the rack-bar is provided with small teeth 'or serrations 33, that engage against the pointed end of the bar 22, and as the rack-bar is moved upward step by step the successive serrations are entered by the point of the bar and the rackbar is held in the position to which it is elevated. The rack-bar is operated by a pawl 34, that is hung at one end of a lever 35, pivoted on a bracket 36 and hearing at its opposite end a Ward movement of the pawl. The pawl-carrying end of the lever 35, together with the pawl, is heavier than the opposite end, so that the pawl and'this end ofthe lever will move down by gravity. In this manner the rapid ity with which the rack-bar is moved tore lease" position may be accurately adjusted, and by thus adjust' the length of time which the roller 18 iS ll fiOWed to remain in engagement with the buncher-cam the quantity of yarn wound to form a bunch may be adjusted. Further adjustment may also be accomplished by altering the osition of the pin 30 so that the rack will e raised to a greater or less distance before released.

The bar 24 is provided with guides 40 for the reception of a slidable bar 41, the outer end of which is pivoted to a hand-operated lever 42, that is pivoted on a bracket 43, projectin from lever 19'. The hand-lever is force outward from the lever 19 by means of a. small compression-spring 44. At the inner end of the bar41 is a plate 45, thatis arranged to engage with the pawl 34 in order to prevent the latter from remaining in contact with teeth of the rack b'ar while the parts are be.- ing ad'usted to" osition for the formation of a fresh unch. n the o eraticn of this .portion of the mechanism tile pawl'34is reeiprd, eated until the end of the-rack-bztr is above the bar22, whereupon the spring 21 acts to pullout the bar 24and bar .41, together with the rack-bar, and the latter will move away from the pawl, while the opposite end of lever 19 moves in the direction of the builder-arm and carries the stem 17 over until the roller 18 moves into contact with the builder-cam 15. In effecting readjustment of the parts the operator grasps the handled lever 42 and the end of the lever 19, and b pressing them together the bar 41 is forced inward until plate 45 holds the engaging end of the pawl well out of contact with the teeth of the rack-bar, so that said rack-bar when pushed be ond the pointed end of the bar 22 ma -fal by gravity to its lowest position in rea iness for another operation .In order to place the bunch in proper osition on the cop or quill, it is necessary t at the machine. This slidhble frame 51 is con nccted to a fixed eve 54 on the bracket by means of a helical tension-spring 55, that tends normally to pull the left, and thus move the traverse -chain and rocker-arms and depress the lifter-rods D.

This movement, however, is resisted by the counterweights. of the lifter-rods, and the spring 55 is not strong enough to overcome the resistance thus cfl ereih'so'thnt the tlnV- erse-cha-in is held under stress and is moved, as usual, in one direction by the builder-arm and in the other direction" by the counterwei hts of the lifter-rods, v

' he bracket 53 is provided with a slot 57, in

which spivot-pin58 may be locked, and on the pivot-pin is mounted a hook 59-, that is hold upward by a spring 60,.sz1id-hook serving to engage with the frune 51 and lock thc ssm e in the position shown inFig. 3 in case said frame 51 is moved to the left. To RCCOlll-r plish this, the rockerdrsme of the first lifter rod is provided with a pedal 60, which. may

be depressed by the operator, thus removing the influence of the counterweight from the traverse -chain, and as soon as'this is done the spring-"55 draws the frame 51-to the left, and the hook-5S) immediately engages and locks said frame in its adjusted. position, after which thehook may be removed and the counterweight again will be allowed to act.

The edjustinentof'the roller 50 takes up a portion of the traverse-chain and pulls down the ring-rail to the proper point for the forma- -tion of the bunch, and as the small bunchercams 16 move over the roller'l 8 the builderarm will be oscillated through it short arc,

and the movement will be transmitted through the trsverse-chein to theringmsil during the for 'mation of the bunch.

The hook 09 is provided with an opening for the passage of a vertically-movable rod the frame is locked bythe hook 59 the downweirdressure of the pedalis-relieved, and the ot er parts being edjustedfwith the'roller 18in alinement with thebuncher-csmthe op- "citation proceeds. end lowered very slightly, but to an extent The builder-arm is raised sufiicient to traverse the ring-rail the full height of the bench at eechoperetion, so that the tread iscro'ssediand a relatively hard bunch is formed'on which the subse' ucnt winding may proceed'wi-thout danger o the operation -progre'sses each til ne the buildererm is moved down the iuilder-eani' will'nlso frame 51 to the,

buildeiwirm to engage the roller 37 and rock the lever 35, this movement being transmitted through the pawl 34 and the rack-bar being raised one or more teeth, in accordance with the distance throughm'liich the lever 35 moves. As soon 7c as the lower end of the pawl-bar is level with I the top of the bar 22 the spring 21 acts to pull the ber24 and the rack-'baroutward,
