The yarn or thread is pulle "9 of the-bobb n tim w undeniq the t me. .Z'li provide. yarn; pa ka e .ne kti illerly illustrated in Figures 1 and 2, the yarn being twisted as it is wound from the bobbin onto the package by the rapid rotation of the bobbin. A bar 22 is slidably mounted on the frame and disposed substantially at right angles to the yoke ll. The rear end of this bar is connected to the yoke by a tension spring 23 and the front end of the bar is provided with a hand knob 24. Intermediate its length the bar slides through a fixed guide 25 which guide carries a pin engageable in a notch in the bar to lock the bar in a retracted position. The bar is moved to its retracted po-' sition by manual pressure on the knob 24 and when the bar is in its retracted position the spring 23 pulls the yoke back toward the roller l5, so that this roller engages the surface of the tube 20 and the surface of the yarn package as the yarn is Wound onto the tube to impart rotational movement to the package at a substantially constant peripheral speed. When the yarn breaks or is completely pulled off of the bobbin the bar 22 is released, in a manner to be later described, to

permit the yarn package to fall away from the driving roller and come to rest, so that the completed package can be manually removed from the forks and taken to the steam room.

During the first part of the spinning operation and before the bobbin |3 comes up to full speed, the yarn is loosely twisted and is not suitable for use in weaving cloth. This loosely woven yarn is wound separately on the tube 20 at one end of the tube, as indicated at 26 in Figure 1, and is called a transfer. It is usually necessary to wind from six to ten yards of yarn at the beginning of the spinning operation onto the tube before the winding of the yarn package 2| is begun. It will be noted that the transfer '26 is spaced'from the adjacent end of the package so that the transfer can be removed and discarded without wasting any of the yarn in the package.

After the transfer and the package'have been completely wound onto the tube, the loaded tube is taken to the steam room where the yarn is steamed to deaden it and render'it easily removable from the tube. The loaded tube is then carried to a warping machine where the yarn is wound off of the package onto the warp beam of a loom. At this point the transfer 26 is removed and broken off, a sufficient length of the transfer being left trailing so that the outer end of a subsequent package can be knotted to this trailing end of the transfer to provide a continuous warping operation.

In the Spinning operation the yarn is wound onto the package through suitable yarn guides and a level winding device which distributes the yarn evenly over the package and tapers the ends of the package, as is particularly illustrated in Figure 1. With the conventional machine it is necessary to pull the yarn at the beginning of the operation and to guide the yarn constituting the transfer 26 onto the tube by hand until, in the operators judgment, the proper amount of yarn has been wound into the transfer, whereupon the yarn is released and the level winding mechanism starts building up the yarn package at a location slightly spaced from the transfer winding.

With the transfer winding attachment of the present invention the winding of the transfer is mechanically controlled and the yardage of yarn wound into the transfer is definitely predetermined.

A fixed bar 21 extends transversely of the face of the winding machine between the spindle H and the yoke l1 and a support 28 is inclined downwardly from the under side of this bar toward the yoke. A Y-shaped lever 29 is pivotally secured at one end to the support 23 at the end of the latter remote from the bar 21 and one leg of the lever has a reduced extension 30 slidably received in a socket 3| pivotally mounted on the upper end of a standard 32 carried by the yoke, a compression spring 33 being interposed between the socket and the leg of the lever at the proximal end of the reduced portion 30. An arm 34 is pivotally connected at one end to the end of the lever 29 remote from the pivotal connection of the lever with the support 28 and this arm 34 carries at its end remote from the lever a thread guide eye 35 through which the thread passes from the bobbin l3. This arm 34 maintains the eye 35 directly above the bobbin during the spinning operation, but the pivotal connection between arm 34 and lever 2.: permits the arm and eye to be swung out of the way when the bobbin is changed. The eye is also moved vertically as the size of the yarn package increases to maintain a substantially even tension on the yarn.

Upon leaving the eye 35 the yarn passes through a guide 31 on a cam plate 38 pivotally mounted on the guideway 25 and carrying at one end a pin engageable with the bar 22 for releasing the bar when the thread breaks or has been exhausted from the bobbin. After leaving the guide 31 on the plate 38 the yarn passes over a fixed guide roll 39 and from the guide roll passes the yarn guiding head 40 on the distal end of the traversing arm 36 which head feeds the yarn onto the yarn package 2| and level winds the yarn from one end of the package to the other.

A traversing rail 4| extends substantially horizontally across the face of the winding machine and substantially parallel to the fixed bar 21. This rail is constantly reciprocated by suitable power operated means, not illustrated, the range of its reciprocatory movement being less than the length of the yarn package 2|. A carriage 42 is mounted on the rail 4| for movement therewith and comprises an elongated member of channel shaped cross section receiving the rail interiorly thereof. The rail 4| is slidably mounted in suit able' guide brackets carried by the machine frame It) and is of elongated, rectangular cross sectional shape and so positioned that its major surfaces are disposed at an angle of approximately 45 degrees to the horizontal. The carriage has an extension 43 which projects therefrom toward the yoke I1 and is substantially horizontally disposed. A bracket 44 is pivotally mounted on the extension 43 by a pin 45 extending through registering apertures in the bracket and extension 43 for movement about a substantially vertical axis which is disposed substantially at right angles to the rail 4| and the traversing arm 36 is pivotally connected at its lower end to the bracket 44 for movement about an axis which is substantially horizontal and substantially parallel to the rail 4|.

When the carriage 42 moves with the rail 4| the traversing arm 36 and its thread guiding head 40 are carried back and forth longitudinally of the tube 20 to distribute the yarn in the package 2| evenly from one end to the other end of the package.

A flat plate 46 is mounted along one edge on the upper surface of the fixed bar 21 and projects from the fixed bar toward the reciprocating rail 4| This plate, as is particularly illustrated in Figure 6, extends longitudinally of the bar 21 and is provided with one or more longitudinally extending ribs 82 which engage in notches in the end plate to restrain the stem against rotation relative to the ratchet wheel while permitting longitudinal sliding movement of the stem relative to the end plate I8.

A coiled compression spring 83 is disposed between the end plate 18 and the adjacent end of the pin II and resiliently urges the pin toward the rail 4|.

The ratchet wheel 15 is provided in its end adjacent the carriage 42 with a series of partly spherical recesses 84 and a'ball detent 85 is mounted in a recess in the carriage and spring pressed into the depressions or recesses 84 to provide a clicker between the ratchet wheel and carriage to determine the extent of manual rotation of the ratchet wheel by the hand knob 8| in terms of the number of ratchet teeth moving past a fixed point on the carriage.

With this arrangement, the pin II can be raised against the force of spring 83 by pulling upwardly on the knob 8| until the wings 13 of the pin are above the upper ends of the stud 66. By then rotating the knob the ratchet wheel and the pin will be simultaneously rotated relative to the stud to bring the wings 13 on the pin out of registry with the grooves 69 or 18 in the stud, so that the pin will be held above the rail 4| until it is rotated to a position at which the wings 13 are returned to alignment with the grooves. At this time the spring 83 will force the pin down and, upon reciprocation of the rail 4|, the lower end of the pin will engage in the beveled portion at one side of the aperture 62 in the rail causing the carriage to start to move with the rail and pull the roller 49 out of the notch 50 or in which the roller is engaged. As soon as the roller is freed from the corresponding notch the pin II is projected full into the aperture 62 in rail 4| and the taper of the pin provides a tight fit of the pin in the aperture which will prevent any lost motion between the carriage and the rail.

After the pin has been raised by the knob 8| out of the aperture 62 and away from the rail 4| and rotated so that it is supported on the upper end of the stud 66, the carriage can be manually moved along the rail 4| in either direction until the roller 49 is received in one of the notches 50 or 5|. As long as the roller is held in one of these notches by the associated spring 53 the carriage will be held against movement and the traversing thread guide will be held adjacent one end of the package tube 20 for the winding of the transfer yardage of yarn on the tube adjacent the corresponding end of the latter.

The notches 50 and 5| are disposed somewhat beyond the limits of normal reciprocating travel of the carriage when connected to the rail 4|, so

that the roller 49 will not enter either of these 6 notches after the carriage has been reconnected to the reciprocating rail for winding the yarn package 2|.

In order to rotate the pin 1| back to a position at which the wings l3 register with the proper grooves in the stud, a ratchet pawl 86 in the form of a flat leaf spring having a hook 81 atone end, is connected to the rail 4| for movement with the rail and is engageable with the ratchet teeth ll of the ratchet gear when the roller 49 is in one or the other of the notches 50 or 5|.

An auxiliary rail 90 extends along the rail 4| and is spaced outwardly therefrom so that it is clear of the carriage 42. This auxiliary rail is connected to the rail 4| for reciprocatory move- 8 ment therewith and a clamp 9| is secured on the auxiliary rail 90 adjacent the carriage 42. The pawl 86 is provided intermediateits length with apertured lugs 92 which are disposed at respectively opposite sides of the clamp 9| and pivotally.

the pawl 86 is provided with a tapped hole and. an adjusting screw 94 is threaded through this hole and bears at one end against the adjacent side of the rail 90 to position the hook formation 81 for engagement with the teeth TI of the ratchet wheel. This screw is secured in adjusted position relative to the pawl by lock nut 95 threaded onto the screw and bearing against'one side of the pawl.

After the carriage has been released from the reciprocating rail and moved beyond one end of its range of reciprocatory movement so that the roller 49 is secured in one of the notches 50 or 5| by the associated spring 52 or 53, upon a reciprocation of the rails 4| and 90 the hook formation 81 on the pawl 86 will engage the ratchet teeth and rotate the ratchet wheel step by step in the same direction to that in which the wheel was rotated by the hand knob 8|, so that after a predetermined number of reciprocations of the rails, the wings 13 on the locking pin will be brought back into alignment with the grooves in the stud 56 and the pin will be forced by the compression spring 83 into the aperture 62 in the rail 4| to reconnect the carriage 42 to the rail. As explained above, this pulls the roller 49 out of the notch in which it is engaged and causes the carriage carrying the traversing thread guide to reciprocate with the rail. During this normal reciprocation of the carriage with the rail the roller 49 will not re-enter either of the notches 50 or 5| and the hook formation 81 on thepawl 86 will not engage the ratchetteeth 11, since the pawl and ratchet wheelnow reciprocate together with the carriage and the rails 4| and 90.

ing rail to wind the yarn package. Thus, the only attention required on the part of the operator is to set the attachment for the desired amount of yardage in the transfer winding and the attendant can quickly set the attachment as he threads the yarn from the bobbin through the yarn guides and connects it to the package spool, not having to wait after each threading until the transferwinding has been completed. The yardage in g5'leach transfer winding is also accurately determined and does not depend upon the judgment of the operator or attendant at the spinning machine. l The reciprocating rail 4| is mounted in modified slide brackets attached to the machine frame, so that the faces of this rail are inclined approximately 45 degrees to the horizontal and the longitudinal center line of the stem 89 and pin H is also inclined outwardly at an angle of' approximately 45 degrees. This is to position the As a definite amount of yarn will be wound.

automatically reconnected with the reciprocatattachment so that the" yarn package 2| will not rubagainst the attachment as the packageis filled, and to provide room for the package to drop away from the associated cork roll at the end of the winding operation.
