Application filed. April 23, 1914. Serial No. 833,919.

To all whom it may concern Be it known that I, GEORGE S. HARRIS, a citizen of the United States, residing at West Point, in the county of Troup and State ofGeorgia, have invented certain new and useful Improvements in Spinning- Frame Builders; and I do hereby declare the following to be a full, clear, and exact: description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to improvements in the art of ring spinning machines, and more particularly to the actuating mechanism for the ring rail, and the object in view is the confining of the traverse during a predetermined number of layers and the automatic release thereof.

WVith this and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as willbe hereinafter specified and claimed;

In the accompanying drawings, Figure 1 is a view in side elevation of a ring spinning frame have applied thereto mechanism embodying the features of the present inven tion, parts being broken away. Fig. 2 is a top plan view thereof. Fig. 3 is an enlarged detail vertical section, the section being taken on the planes indicated by line 8-3 of Fig. 1. Fig. 3 is a detail section on line ti -3 of Fig. 3. Fig. 4 is a view in side elevation of the parts seen in Fig. 3. Fig.5 is an elevation of the builder motion let-off. Fig. 6 is a fragmentary, detail, vertical section taken on the plane indicated by line 66 of Fig. 1 and looking downwardly. Fig. 7 is a view similar to Fig. 3 of a modified embodiment of the. parts.

Referring to the drawings by numerals, 1

indicates an ordinary spinning frame which may be, so far as the present invention is concerned, of anytype, the same being seen in the form of a ring spinning frame which isprovided with the usual ring rail 2, builder motion let-off 8, cable or chain 4, quadrant 5, lever 6, lifter rod and counterbalance weight 8. All of these parts are of common and well known construction, and ordinarily would act to shift the ring rail 2 in a manner for effecting the usual traverse and gain in the filling of bobbins.

The present invention contemplates the provision of means for varying the movement of the ring rail so that instead of havmg the regular traverse, when at its ably of the wheel type. A spring 13 is interposed between the handle 12 and a portion of sleeve .10 and presses the handle in a direction for causing the shaft 11 to move" outwardly when free to ,havelongitudinal travel. The inner end portion of shaft 11 is fixed to a cylinder 14 having a portion of its periphery formed into a vratchet 15 and having a smooth peripheral portion indicated at 15 formed integral or otherwise fixed to the inner end ofthe cylinder 14 and projecting inwardly therefrom is a, stub shaft 16. As a matter of convenience of manufacture, the shaft 11 may simply be formed with an enlargement with which the shaft 16 is formedintegral and onto which the cylinder 14 is fixed by keys 14 Obviously the parts may be produced by other appropriate methods of manufacture. The cylinder 14 has a bore of'a diameter adapted to receive the inner end portion of the sleeve 10, so that the cylinder may slide freely along and surrounding sleeve 10 when the parts are free for such movement. A, lug or detent 17 extends outwardly from the sleeve 10 beyond the circle described by the bore, of cylinder 14, so that the lug is adapted I I I to engage the outer face of the cylinder and to retain the same against outward-move- I 14 is provided withv an adjustable segmental stopconsisting of an arcuate plate 19 having alongitudinal, central slot 20 through which extends the bolts 21, 21, threaded into the end of the cylinder 1d. The bolts 21 are threaded into apertures 22 in the cylinder 1%, of which there are a greater number than the number of bolts so that the bolts may be adjusted and thus allow a greater amount of adjustment of the stop than that afforded by the length of the slot, although for all ordinary purposes the adjustment effective by the excess length of the slot over the distance between the bolts will suffice.

Upstanding from the vertical support of the quadrant 5 is a bracket 23, to Which is pivotally connected a pawl 24: disposed to engage the ratchet 15. The pawl 2 1 consists of a pivoted lever having a longitudinal slot engaged by adjusting bolts 26 carrying a plate 27 having a ratchet tooth 28. The bolts 26 are adapted to be adjusted along the slot 25 for varying the relative location of the tooth 28 with respect to the teeth of ratchet 15, whereby a single stroke of the pawl may be caused to move the ratchet a distance equal to a greater or less number of teeth of the ratchet varying from one tooth at each step to four teeth or more according to the relative sizes of the teeth of the ratchet and the tooth of the pawl, and proportional to the circumference of cylinder 1 1. A link 28 pivotally engages pawl 24: between the pivotal connection of the pawl with bracket 23 and the tooth 28, the said link extending downwardly to and enan actuating lever consisting of a crank, arm 29 fixed to or formed integral with a rock shaft 30 journaled in a sleeve 31. The sleeve 31 is fixed as a bracket to the lifter rod lever 6 and an actuating treadle 32 engages the outer end of shaft 30 so that when said treadle is depressed the shaft will be revolved for lifting the link engaging end of arm 29, and thus lift link 28 and pawl 24% for moving the pawl out of engagement with the ratchet. To enable longitudinal adjustment, the link 28 is preferably formed in two sections united by a pin and slot connection 33.

Cooperating with chain 1 is a deflecting lever which consists of a flat bar, or other straight link, having lon itudinal slots 35, 35, through which extend bolts 36, 36, each having a hook-shaped end portion 37 engaging the chain l and adapted to be clamped against the chain by the action of the nuts 38 threaded on the other end of the respective bolts 36, and disposed at the op-- to plate 3 1, and extending with the longitudinal axis of the lever substantially at right angles to the longitudinal axis of the shaft. Other angular relations might be assumed for effecting varying degrees in the defiection of the chain at, but for the purposes of disclosing a preferred embodiment the relative disposition of the parts named is found effective. The lever 39 extends obliquely across the shaft 16, the oblique disposition of the lever being caused by the location of the clamping bolts 36 nearer the quadrant 5 in the length of chain 1 than should the said bolts be located if the lever were to assume an upright position. The degree of incline from the vertical may be varied by adjustment of the bolts 36 and will be proportioned in practice according to the extent of deflection of chain l desired with each stroke of the chain. The extent of defiection may also be varied by including a greater or less portion of the chain between the clamping bolts, as by adjusting the bolts longitudinally of their slots 35.

In operation, the let-off mechanism 3 is actuated in the usual manner, and the chain 4 is thus reciprocated and given its regular gain at each successive stroke for actuating the quadrant- 5 and thus through lever 6 and. rod 7 and with the aid of the counter-balance weight 8 reciprocating the rug rail 2 in the usual manner, except that at the beginning of'the operation of the ring rail, when it is in its lowermost position, the defiector lever 39, at each reciprocation of chain 4, strikes against the detent or stub shaft 16 and is tilted thereby causing the plate 34 to assume the position shown in Fig. 1, so that the chain l is deflected thereby to the extent desired for suppressing that portion of the stroke in excess of what is desired in the way of traverse of the ring rail, so that the traverse is suppressed or shortened during as many strokes of the ring r il as occur while the detent 16 is in position for engaging lever 39. The number of such strokes may be varied by varying the extent to which the cylinder 1 1 must be revolved before the slot 18 registers with detent 17, and also by varying the number of teeth passed by the tooth 28 with each reciprocation of pawl 24. In starting the operation the operator presses the wheel 12 inwardly from the position indicated in dotted lines in Fig. 3 to the position indicated in full lines therein, and then revolves the shaft 11 together with cylinder 14 until the end of stop 19 strikes detent 17, the stop having been set for the required number of reciprocations before the release of the lever 39 is accomplished. The opera tion of winding yarn on the bobbins begins and continues with the short traverse producing the bunch at the lower end of the bobbin until the pawl 2 1 has moved the ratchet 15 a distance sufficient for causing groove 18 to register with detent l7, and,

soon as detent 16 moves out of the path ofdeflecting lever 39 the quadrant 5 will have its full stroke with each stroke of the let-off mechanism, and the ring rail will thus be given its full traverse and from then on until the filling of the bobbinsis completed the operation of the mechanism is'just'the same as if the deflector were not present at all.

At certain times during the operation of the structure it may become desirable to manually control the movement'of ring rail 2, and to attain this result the treadle 32 is provided, which may be depressed by the foot of the operator and whose foot can at the sam time be caused to actuate the lever 6 and thus shift the ring rail 2 as desired, the actuation of the treadle 32 causing the link 28 to be lifted and the pawl 24 thus moved out of operative position, so that the manual actuation of the ring rail will not interfer with the relative position of the part-s or their continued relative action when the foot'of the operatoris removed. It is to be noted that when the cylinder 14: moves outwardly under the action of spring 13, the pawl 24 will'not effect any further action since the tooth 28 will have been relatively brought to a position in engagement with the smooth peripheral portion 15 of cylinder 14:. To effect this-movement of the tooth 28, the inner terminus of each recess formed by the ratchet teeth 15 is curved outwardly, as clearly seen inFig. 3, so that when the cylinder 1 1 moves from the full line position in Fig. 3, to the. dotted line position, the tooth- 28 will readily ride up the incline and assume a position: out of engagement with the ratchet. 1

The deflection of the chain 4 as the same is reciprocated takes up a proportional amount of the reciprocation and proportionally :detracts from the otherwise full stroke of the quadrant so'that the traverse V of ring rail 2 is suppressed or reduced proportionally. Thus an appropriate bunch is formed at the lower end ofaeach bobbin.

This mechanism is especially well adapted for filling bobbins adapted for use with feelers requiring slotted bobbins. With this type of feeler the yarn wound over the slot in the bobbin prevents the feeler from entering the slot, but when the yarn in unwinding exposes the slot the, feeler enters and causes the loom to automatically transfer a newbobbin to the shuttle. One of the essential, objects of the present improvement is to wind the yarn on the bobbin below the point where the feeler enters the slot until the required amount of yarn has been wound on, and then the ring rail is automatically allowed tohave its full traverse for, Winding yarn over-the slot where the feeler enters. The invention is ,alsowell adapted for winding bobbinsfor the feelers of regular looms, since by its use a feeler bunch can be built at the base of the bobbin of any predetermined size, and the mecha nism can. then be released, as by the automatic outward movement of cylinder 14 for allowing the ring rail to. have its full stroke and to thus continue to regularly wind on V the yarn. 1

- The means'for causing the stub shaft or detent 16 to. move out of the path of the deflecting le'veris capable of considerable variation or modification as will be obvious, one modified form being seen in Fig. 7 wherein the parts have been given reference characters corresponding to those of the main showing but primed to indicate their reference toa modification and the same description applies. A sleevelO is provided. in which shaft 11 is, threaded, the outer end of the shaft being provided with a handle 12". No spring is employed and the shaft 11 is caused'to move to its inner position by rotating handle 12 in a direction to screw the shaft inwardly. Cylinder'le is-formed with ratchet 15 engaged by the pawl 2 t.- No lug or detent is needed to prevent outer movement of cylinder 1%; The cylinder is provided with the stub shaft or detent 16 which is moved laterally outwardly when the pawl 241: revolves cylinder 14 and thus'causes shaft 11 to be threaded outwardly along sleeve 10.
