Abstract: 24,638. Wade, H., [Leeson, J. R.]. Dec. 24. Winding - machines; stop - motions; threadguides; stop-apparatus, non-automatic.-In machines for winding yarn, thread, wire, &c., in which the winding is stopped automatically at the completion of each layer of the winding, the mechanism for stopping the winding is held inoperative by detent means which is released by a member mechanically operated by the traverse mechanism. The invention is described as applied to a machine of the type described in Specifications 91/13 and 4091/13, in which both wire and yarn are laid on the same spindle, the wire in close spiral by a slowly traversed guide, and the yarn in open spirals by a quick-traverse guide. The spindle shaft b, Fig. 1, is driven from the pulley B through the clutch B', and the cam shaft c is driven through the belt b<1> from the shaft b. The shaft c carries two cams C, C', the former of which is keyed to the shaft and operates the yarn-guide, and the latter of which is free on the shaft and driven through the medium of a worm gear c<1> as described in the aforesaid Specifications and in Specification 16,421/14, and operates the wire-guide. The guide G', Fig. 2, for the yarn comprises a forked guide g<2>, g<3> carried by an arm g pivoted on a rod h, and an arm g<1> sliding in a groove in a parallel rod h<1>. The arm g<1> is connected by a link to a lever operated by the cam C. The wire-guide G is mounted on a frame E carrying parallel rods e, e<1>. A slotted arm D is mounted to slide on these rods, and embraces at its lower end between collars d<5> a sleeve d'. The sleeve carries an arm g<4>, having at its upper end a yoke g<5> in which are mounted the grooved guide-wheels g<6>, g<8> for the wire. The arm D is reciprocated by a link K and lever F operated by the cam C'. The lever F has a slot f<3>, and the link can be adjusted as described in Specification 13,176/13. The machine can be started or stopped manually by the handle L rocking a shaft l carrying an arm L', to operate the clutch mechanism, which may be of the type described in Specification 6097/06, [Class 80, Mechanism &c.], and a brake shoe m to engage a grooved pulley M on the shaft b. The handle L is drawn in the direction to release the clutch by a spring l<21>, but is normally held against such movement by a notch n in a lever N engaging a detentshoulder l<4> on an extension d<3>. The lever N can be raised by a finger-piece n<2> against the action of a spring n<3> to release the detent and stop the machine. To stop the machine automatically at the completion of each layer of wire, the lever N has an extension n<4> carrying an adjustable piece n<8> adapted to engage and be raised by a rod O. The rod O is bevelled off at its lower end and rests in a cavity r in a rod R. The rod R is arranged between adjustable springs s in bearings p<1>, p<2>, and is moved laterally at the end of each traverse by a piece f<2> of the traverse lever F engaging one of the shoulders r<2>, r<3>, in the rod R. Lateral movement of the rod R causes the rod 0 to be raised out of the cavity r and to strike the piece n<8> and operate the lever N. To re-start the machine, the handle L is pushed over in the direction t, Fig. 2, whereupon the clutch is put into action again. The commencement of the traverse allows the springs s to restore the rod R to its normal position with the cavity r ready to receive the rod O. The spring n<3> presses the lever N down to cause the notch n to hold the detent l<4>. The handle L is then released.
