Abstract: 265,927. Universal Winding Co., (Assignees of Parks, E. F.). Feb. 9, 1926, [Convention date]. Winding-machines; spindle-driving apparatus; stop-motions.-Relates, to machines for winding yarns, thread, or the like having a device such as a progression wheel adapted to contact with the winding to advance the traverse means. Means are provided to effect an initial lateral adjustment of the. winding spindle towards and from the contact device to regulate the diameter of the yarn package to be wound, and such means may serve also automatically to adjust the speed of the spindles in accordance with the adjustment of the diameter of the package; the oscillating traverse arm is adapted directly to engage detent means controlling the stopping mechanism; and a number of winding-units, each comprising a spindle and traverse mechanism embodying the foregoing features, are detachably mounted independently of each other in a casing and so arranged that the spindles project from the casing when the unit is in operative position, and are independently coupled to a common driving-shaft, so that each may be uncoupled and detached as a whole from the casing without disturbing the coupling of the others. In the arrangement shown, each winding-unit is mounted in a partitioned casing 2 provided with a protecting cover and serving as an oil reservoir, and comprises a winding-spindle 4, a reciprocating traverse rod 6 provided with a progression wheel device 10, and a heel-forming former 15 for use when winding pin cops or quills, the rod 6 being formed in two sections of which one is displaced laterally with respect to the spindle by the former 15 as described in Specification 24611/08. A shaft 28, secured by screws in arms of a frame 20, carries the traverse cam and a frame 32 provided with a cross member 36 in which the winding-spindle 4 is journaled. The frame is pivotally adjustable by means of locking-screws about the shaft 28 so as to vary its distance from the traverse rod and thereby to determine the diameter of the yarn package. This adjustment of the spindle also varies the position of its driving-disc 55 relative to the friction wheel 60 on a shaft 56 so that the speed of the spindle is varied in accordance with the diameter of the package. The discs 55 are preferably faced with cork, fibre, or other resilient material. The cam is provided with an integral gear 73 which is driven from the spindle through change gears 75, 82 carried by an arm adjustably secured to a lug projecting from the spindle bearing. The traverse rod 6 is carried by a cross-head 92 reciprocated by an arm 85 engaging the cam and is provided with a series of holes interchangeably engaged by the stud of a roller 90 which engages the slot of the cross-head. The stop mechanism comprises a rockable bar 95 provided with a lever 99, Fig. 5, which is connected to a spring 101 so that it tends to engage the bevelled flange 66 of the friction disc and to move it along the winding-spindle against the action of a spring 64 away from the friction wheel 60. A sliding detent rod 105 normally withholds the lever 99 but, upon breakage or exhaustion of the yarn, it is withdrawn against the action of a spring 108 by the traverse arm 85. A shoulder 114 on an extension 113 of a trip lever 110 mounted on the rod 105 falls into the path of the arm 85 when released by suitable detector mechanism connected to the trip lever by a rod 112. The extension 113 of the trip lever is provided with an offset portion 115, which embraces the rod 105 and engages a collar 107 fast on the rod and abutting against the spring 108. The rod 105 may be withdrawn manually, or 'bv means engaged by the thread guide upon completion of the winding. To start the machine the rod 95 is rocked by a handle 96 to operate the lever 99 which is thereupon engaged by the detent rod 105.
