'to cause a relative reciprocation between the spindleand uide. The winding spindle 11 rotates in a aring a in the frame A and is driven througha spiral or skew gear I) meshing with a similar gear 0 on the driveshaft d. In the present machine the threadguide 9 is mountedon and reciprocated by a traverse-rod or bar f which slides in a hearing it in the frame A. Reciprocatory motion is imparted to the traverse-bar, f by an oscillating arm 11 on the rocker-shaft j connected to the end of the bar by a linlrk. The arm 71 is formed with a series of holes i i etc.', and a pin is at one end of the link is adapted to be engaged with any one of these holes. By shifting the point of connection of the link 7.: on the arm i the operative length of the latter can be varied to change the length of traverse of the threadguide as desired.

lhe thread-guide proper, designated by the character g, is mounted on an arm or holder Z which is pivoted to swing on the traverse-bar f. Preferably, the holder Z is constructed of sheet metal formed with a V-shaped portion to which the guide is attached and a bifurcated extension comprising the two legs Z and Z The extremity of each leg is bent down as shown in Fig. 4 to form the bearing portion Z surrounding the traverse-bar, and bushings Z are preferably inserted in these portions to provide a more extended bearing surface on the bar. At the outer free end of the holder Z means are provided for attaching the thread-guide which is preferably constructed of porcelain Patented ct. enters.

or other vitreous material adapted to resist the wearing etfect of the thread or yarn. The yarn y leads up from the supply, not here shown, and draws through the groove 1' in the top of the guide 9 and thence down to the winding spindle. The tension of the yarn drawing through the groove keeps the under side of the guide pressed firmly against the surface on which the yarn is being laid and provides that the individual 0011s of winding shall be deposited with pres cision and accuracy. As the yarn is disposed in conical layers, which eventually form the pointed nose of the cop, the guide must travel up and down the incline of these layers and this is rovided for by the swiveled bearing of t e guide-holder Z on the rod f. This allows the guide to oscillate toward and away from the axis of the winding spindle at each reciprocation.

The traverse-bar f is formed with screw threads f which extend substantially" the whole length of the bobbin wo md and our invention provides improved means actuated by the bobbin to feed the threaduide along the bar. These consist essentiafiy of a bushing or nut n, preferably located between the legs Z and Z of the thread-guide holder Z and a contact-wheel or friction disk 0 mounted on said nut. The nut n is formed with an extended hub 91, bored to receive the rod f and a flange n at one end, see I igs. 3 and 6. The contact-wheel o is preferably made separate from the nut n, so that it may be detached and wheels of difi'erent diameters substituted, and is held in place by the following novel arrangement: The bore of the wheel 0 fits the hub of the nut and its face abuts the side of the flange n. Adjacent the wheel 0 the hub n is formed with a peripheral groove 1:. and into this groove is sprung a U-sha d wire spring clip u. One end of the wire is bent at right angles to the plane of its loop andextends through a transverse hole w in the wheel 0 and flange a This serves as a means for securing the wheel 0 rotatively on the nut 11 and the loop of the clip it acts to prevent lateral displacement. It will be seen that as the clip u'extends more than half way around the hub n it will tend to bind on the hub and the curved end a of the wire serves as a convenient finger piece to be used in springing the clip out of its groove. The extended part of the hub n is cut away at 11. throughout a portion of its length and in this opening is mounted a bell-crank shaped pawl p. Preferably the pawl p is pivoted on a wire ring 8 which embraces the hub a and is sprung into a peripheral groove n in the hub. One arm 10' of the pawl p extends horizontally along the top of the bar f and is formed at its outer end with a segmental portion 32 The under side of the segment is formed wit-h threads adapted to engage the threads of the traverse-bar; A spring clip t formed as a split ring, see Fig. 7 is sprung into a peripheral groove 7!. in the hub 11. and engages a similar groove on the top of the segment 79 The clip t acts to maintain the segment in engagement with the threads on the traverse-bar but allows it to be raised to release the threads when the pawl is rocked. The pawl p is rocked through its vertical arm p which is formed at its upper end with a convex abutment 12. For rocking the pawl we provide a flanged sleeve 41 mounted to slide on the hub n of the nut n. The flange c on the sleeve '0 is slightly less in diameter than the diameter of the smallest wheel used on the nut, so that it will clear the periphery of the bobbin which contacts with the wheel. The flange 'v' is formed with a rectangular-1y shaped pocket '0 in which the arm of the pawl is located. The rear wall or the pocket 42 engages the abutment p on the arm and when the sleeve 2) is moved in the direction of the arrow, Fig. 3, the pawl will be rocked to raise the segment p clear of the threads on the traverse-bar f. The sleeve 0 is he d in place longitudinally on the nut n by a split ring 1 sprung into a peripheral groove at the outer end of the hub n.

Theoperation of the whole device is as follows: In Figs. 1 and 2 the dot-and-dash lines represent a bobbin B wound on the usual wooden tube B which is formed with a conical butt B at its base end, see Fig. 2. The first layer of winding is deposited on this coniform surface, and subsequent layers are disposed in corresponding planes stepped progressively forward along the tube to form the extended body portion of the bobbin-which terminates in the conical delivery end or tapered nose. For the sake of clearncss, the thread-guide g and progression-wheel 0 are here shown as advanced some distance along the traverse-bar f, but at the beginning of the winding of a bobbin they are adjusted to a position in line with the base of the conical butt. B on the tube B. The winding spindle a is rotated through the means before described and the traverse-bar f, actuated through its connection with the arm 2', reciprocates opposite the spindle in the direction of the axis of the latter. The thread-guide g bears on the surface of the conical butt I3 and is traversed by the traverse-bar f to deposit the first layer of winding on this surface. As the guide moves outward along the spindle and returns again to its point of starting the periphery of the progression or contactwheel 0 will contact with the rear edge of the first layer of winding and the rotation of the spindle will cause a slight rotation of the wheel, as indicated by the arrows in Fig. 4. The threaded end of the pawl p, see Fig. 3, is normally held in engagement with the threads on the traverse-bar f by the spring clip t, and as the wheel 0 is rotated it turns the nut 'n and the engagement between the threads on the bar and those on the pawl causes the nut to feed along the bar. The wheel. 0 is rotated slightly at each complete reciprocation of the traverse-bar so that the nut 12 has an intermittent progressive movement along the bar. gagement of the nut n with the legs of the The enomers thread-guide holder Z causes the latter to feed along the traverse-bar and therefore the thread-guide g' is advanced along the winding spindle to lay the yarn in successive, coniform layers stepped progressively forward alon the tube B.

After a ho bin is completed it is necessary to return the thread-guide g to its initial position to start the winding of a new bobbin. This is accomplished in a very simple manner by a single movement of the hand, in one direction only. The operator merely presses on the side of the flange 'v of the sleeve 1) in the direction indicated by the arrow, Fig. 3. The pressure of the operators fingers acts first to slide the sleeve '0 to rock the pawl 12 and release its threads from the threads of the traverse-bar. Continued pressure, after the awl is released, will slide the nut n-and guide-holder Z bodily on the bar to return the thread-guide to the proper position for starting the wind ing of a new bobbin.

In previously used devices of this sort the arrangement has been such .as to require separate operations of the hand to release and reset the guide. With one well known means it is necessary to press the wheel and nut out of alinement with the bar before it can he slid along the latter; and in another it is. necessary first to pull out a catch or spring latch before the wheel can be moved. In our present arrangement it is only required to push the wheel in the direction it is to be moved and the release of the threadengaging element is accomplished automatically. This improvement is of great value as requiring less thought and skill on the part of the operator and also as saving time and effort in operating the machine. The ease and despatchwith which the guide can be adjusted make for more expeditious starting of the winding and hence increases the production of the machine.

Further improvement is realized in the present construction, in that it provides for easier and more positive rotation of the contact-wheel during the operation of the machine. The extended hub of the nut 72 gives a long bearing on the bar f, so that the wheel will not cramp or run out of true and this results in the bobbin being built with a straight, true periphery throughout its whole body portion. Bobbins which are perfect in this respect can be wound to a maximum diameter without crowding in the shuttle and will deliver the yarn without breaks and with a uniform tension. When a bobbin is wound imperfectly, with an uneven periphery having ridges and hollows, the bulging places are apt to pinch against the sides of the cavity in the shuttle and the yarn will not unwind freely. Variations in tension of delivery will also be evident the housing of the pawl to prevent loose ends from catching in it; or hindrance in its action from lint and dust. It will be seen that where the threads on the pawl engage those on the bar the parts are com letely mclosed and the ends of the nut fit tig tly around the bar to prevent the insinuation of dust. The,

peculiar formation of the thread segment on the pawl further adapts it to rct as a plow or clearer to clean out the spaces between the threads on the bar as it rotates about the latter.

It will be evident that our improved device might be applied to machines in which the spindle is longitudinally reeiprocated instead of reciprocating the bar. Other modifications might be made in the form and structure of the device without departing from the spirit and scope of this invention. Therefore, we do not limit ourselves to the precise construction and arrangement here shown, but
