Abstract: 209,852. Vickers, Ltd., and Pool, W. Oct. 23, 1922. Reeling-machines; stop-motions.-Relates to machines for winding yarns or filaments on to the swifts of a series of units in a cross-wound or diamond pattern. The yarn guides D are carried on a tube d<1> oscillated by parallel levers d<2>, d<3> to effect the crossing of the yarn, and are moved longitudinally of the swift by means actuated by counting-mechanism at the completion of anv one hank, so that several hanks are consecutively wound on each swift E. Each swift is connected at one end by a ball joint to a short shaft e<2> mounted in a lever P and carrying a friction wheel F driven from a shaft B. The yarn passes over a fixed guide C around a roller c<1> on a lever c<2> to the guide D. The levers d<2>, d<3> are oscillated by a bell-crank lever g<6> operated by a crank-pin g<3> on a wheel driven from the shaft e2. Each guide engages recesses in a slotted spacer-bar J and is thereby fixed relatively to the tube during the winding of each hank. Upon completion of each hank, the bar J is moved about its pivots j<3>, as described below, so as to free the guide from one recess and to allow it to be drawn along the slot j<2> into the next recess to wind the next hank, by means of a spring in the tube d<1>. A pair of ratchet wheels, of which one has one more tooth than the other, are each provided with bosses having recesses h<5>, Fig. 5, and are rotated by a ratchet h<9> operated by the lever g<6>, so that, when the recesses h<5> register, a bowl h<7> on a lever h<6> enters therein and the lever h<6> is raised and obstructs the movement of and thereby turns the bar J about its pivots. Each swift is stopped and braked when the reeling is complete and upon breakage of the yarn by means of toggle levers N, N<1>, Fig. 2, which are connected to a fixed pivot r<1> and to the lever P, the central pivot n<3> being connected to a retaining member M<7> which normally is latched by a cateh M<6> so as to prevent a weighted cord n<2> from straightening the toggle. The catch M<6> is operated by the lower member M<1> of a parallel linkage formed by an extension M<3> of the lever c<2> supported by the yarn and an extension of the arm d<2>, the end of the member M<1> being supported by a lever K. The linkage oscillates with the arm d<2> and the member M<1> is normally clear of the catch, but upon breakage it is raised by the falling of the lever c<2>, and, when the swift is fully wound, by the removal of the support K by the guide D. The toggle levers lift the lever P, thereby removing the disc from its driver and bringing it against a brakeband. The Provisional Specification describes an arrangement for moving the spacer-bar comprising two ratchet discs, of which one is provided with two notched flanges and the other with a tooth which, during the rotation of the discs, sucessively enters a notch in each flange, thereby allowing one disc to be moved by a spring relatively to the other and to such an extent that a flange or nut on the hub engages and operates the spacer-bar.
