Abstract: 22,153. Stubbs, Ltd., J., and Stubbs, J. H. Oct. 9. Winding-machines; driving-arrangements; stopmotions; tension-arrangements.-Relates to machines for winding yarn, thread, cord, twine, &c., of the kind wherein the traverse guide is maintained in contact with the spool and is reciprocated by a cam in driving-connexion with the spindle, and wherein are employed loose driving-pulleys and clutches, which are braked after disconnexion from the pulleys, supporting-plates for the guides which may be adapted for winding cylindrical or conical bobbins or spools, and swinging guide brackets which effect the disconnexion of the levers connected with the driving-clutches of the spindles. The spindle is driven by means of a loose pulley i and a @lutch 21 which is slid along the driving- shaft so as to contact with the pulley or with a fixed brake surface, and the guide is pivoted to a reciprocating carriage and pressed against the spool by a pivoted supporting-plate, which carries an adjustable screw to effect the disconnexion of the clutch, and a wedge to prevent the return of the supporting-plate towards the spindle after it has been removed therefrom during the winding. The clutch is moved along the driving-shaft to connect with the loose pulley by means of a rod 26, which is moved horizontally by means of a spring 31 when it is released by a handle 28. The handle 28 is mounted on the rod 26 and is provided with inclined surfaces, so that when moved in one direction it allows the spring 31 to connect the clutch and the driving pulley, and when moved in the reverse direction it moves the rod 26 against the action of the spring and moves the clutch against the brake surface. The handle 28 is partly rotated to effect the disconnexion of the clutch by means of a spring, but is normally held in position to maintain the clutch in gear by means of a catch lever, which may be released by hand, by a detector box when a yarn breaks, or by an adjustable screw on the pivoted frame carrying the guide-supporting plate. The driving-shaft is lubricated by rings w, and the cam shaft by receptacles t. The traverse cam is driven from the spindle through an expansion pulley 105 and reciprocates a slide bar p to which the thread-guide lever is pivoted. The thread-guide is pressed against the spool by means of a supporting-plate l, Fig. 5, which is adjustably mounted, so that cylindrical or conical spools may be wound, on a frame 51, 52 pivoted about a shaft j. The frame is connected with a weighted lever in such a manner that the weight becomes less effective in pressing the thread-guide against the spool as the spool grows, and carries a screw 69, which, when the spool is wound, engages a lever 37 and releases the rod controlling the spindle clutch, and a wedge 67 which co-operates with a cam 71 to prevent the return of the guide towards the spindle after it has been removed therefrom by the growing spool. The lever 37 may also be operated to stop the spindle by a rod 43 connected with a detector box, the ratchet or wiper connected therewith being driven from the cam shaft. The cam 71 may be released by the operative by means of a handle 74. The yarn passes over a guide-rod 95 adjustably mounted on the frame 51, 52, in order to minimise the variation in the tension of the yarn. In the Provisional Specification, it is stated that the speed of the traverse cam relative to the spindle may be adjusted by means of an expansion pulley which transmits motion to a pulley, which may also be an expansion pulley, provided with a pinion which gears with a wheel on the cam shaft, the pulley being mounted on an arm, which turns about a boss on the cam shaft and is adapted to tighten the belt of the pulley, and may be formed as a box with a removable cover to enclose the pinion carried by the arm and the toothed wheel on the cam shaft ; one of the pillars carrying the guide-supporting plate may be provided with a projection to engage a set-screw on the detent arm ; and the spindle or mandrel may be adapted to move away from the guide.
