Abstract: 19,710. Morrison, J. W., and Duckett, R., [trading as Duckett & Morrison]. Sept. 5. [Cognate Application, 25,536/11.] Winding-machines; doffing-arrangements; stop apparatus, non-automatic; stop - motions. - In a machine, Figs. 2 and 4, for winding cops similar to mule cops on mule spindles set closely together, the yarn guides k<6> are carried by a bar k<5> connecting arms k<1> pivoted to arms k<2> pinned to a shaft k<3>. An arm k fixed to the shaft k<3> is, during winding, suspended by a pivoted latch s<5> engaging the top of the frame. A chain j<3> adjustably fixed to the arm k passes under a bowl k<4> adjustably carried by one of the arms k<1> and is fixed to a pulley j<2> on a shaft j, which also carries a pulley j<1>, to which is fixed a chain i<6> operated from the usual copping-motion i to oscillate the shaft j and consequently the yarn-guides k<6>. The weight of the mechanism carrying the guides is balanced by the weight of the copping-motion, and the winding-off of the chain i<6> from the pulley j<1> causes the winding-on of the chain on the pulley j<2> and the consequent gradual raising of the yarnguides. The copping motion gives a uniform chase with a quick drop, and, in order to diminish the length of chase while the cop bottom and nose are being built, or to compensate for the decrease in the diameter of the spindles, chase-varying devices l, l<1> of known type are fixed to the shaft j or pulley j<1>, Fig. 9, and deflect the chain i<6>, the device l ceasing to deflect the chain and influence the chase when the cop bottom is fully formed, and the device l<1> gradually coming into operation as the cop approaches completion. The spindles a are driven by bands from a tin roller b, driven, through a conical friction clutch b<1>, from the shaft c. The shaft f, which carries the copping-motion cam, is driven, through a clutch f<2>, from a wheel f<1> loose on the shaft and driven by gearing from the shaft c, and carries a cam e engaging with a contact-piece d<6> on a brake lever d pivoted at d'. The lever d has a brake surface d' and a rearward extension d<4>, upon which rests a weighted lever g<1> fixed to a rock-shaft g carrying a fork g<2>. When the piece d<6> bears upon the plain portion of the cam e, the brake surface d<2> is out of contact with the tin roller and the extension d<4> is depressed against the action of a spring, thus allowing the shaft g and fork g<2> to rock and thrust the tin roller into gear with the clutch b<1>. When the gap e<1> in the cam is presented to the piece d<6>, the tin roller is put out of gear and braked by the surface d<2> ; this occurs daring the time the quick drop of the yarn guides takes place, and so the binding-thread is laid while the spindles are stopped. Each yarn, before passing to the guides k<6>, passes over a pivoted finger m, and keeps a drop wire m<3> out of the way of an oscillating bar n supported on the shaftj. The bar carries an arm n<1> jointed at n<2> to a cranked lever o actuated through the medium of a rod o' from a lever p, which is operated from a cam p<1> on the cam shaft f. When an end breaks, the corresponding wire m<3> drops and obstructs the bar n, thus causing the lever o to turn on the pivot n<2> and act upon a stud g' on a rod q connected to a lever q<2>. This lever, being rocked, moves an arm f to throw the clutch f <2> out of gear and stop the shaft f, the cams p<1> &c. being so timed that the clutch is disengaged about the time the tin roller would be braked and thrown out of gear. In a modification, the oscillating bar n may engage with the tail of the finger m, the thread passing under a hook and over a hook on the finger to the guides. When a cop is completed, the arms k<1> are at the highest point, and a cross bar k<7> bears against a lever s, pivoted to a hinged lever r and normally supported by a latch s<2>; the lever s is released and causes the lever r to depress the finger m and so stop the machine. On completion of the cops, a few turns may be wound below the bases thereof, by disengaging the latch s<5> and lowering the yarnguides. In a modification, Figs. 18 and 19, the tin roller is not braked when the binding-thread is inserted, and the cam shaft f is driven through gearing by a belt from the tin roller b, so that, when the fork g<2> moves the tin roller out of gear, the shaft f is also stopped. The rock-shaft g carries a lever q<2x> having an extension engaging a brake lever d<x> and operated by a rod q<x> to stop and brake the tin roller, the rod q<x> being operated when an end breaks or when the cops are fully wound as described above. The rod q<x> passes through an eye-bolt in the lever q<2x>, and a spring is arranged thereon, as shown, so that the lever d<x> can be depressed by hand to rock the shaft g and release the brake in order that a few coils may be wound below the bases of the completed cops. The brake levers have handles d<5> projecting to the front of the frame.
