Title: Thread-Rolling Heads.
IPC: B21H3/04
Filed: 1967-01-30
Abstract: 1,172,628. Rolling threads. ROTARY PROFILE ANSTALT. 30 Jan., 1967 [1 Feb., 1966], No. 4399/67. Heading B3M. A rolling head consists of a cylindrical body provided with an annular groove partly accommodating a series of threading or profiling rollers, axles extending from opposite ends of each roller bearing on lands formed on each side of the groove. When the exterior of a workpiece 10, Fig. J , is to be threaded or profiled, the rolling body 12 is annular, and the groove 14 is formed internally of the body. For internal rolling, Fig. 3, the body 12 is grooved circumferentially at 14. The axles of each roller can be of conical form, Fig. 9, the lands which support the roller being of similar shape and movable axially relative to each other to adjust the roller radially. From the working position shown, movement of a sleeve 54 to the right permits radial movement of spring-loaded pins 40 outwardly thus permitting relative movement between the parts 12 and 36 which constitute the lands. Springs 38 urge these parts away from each other, resulting in release of the rollers (which are spring-loaded outwardly in a supporting cage) from the workpiece 10. The rollers may be used for burnishing, knurling or sizing of workpieces.

Patent GB-525058-A (GB)
Title: Improvements in cop winding machines
IPC: B65H54/36
Filed: 1939-02-13
Abstract: 525,058. Winding yarns &c. REINERS, W. Feb. 13, 1939, No. 4692. Convention date, March 5, 1938. [Class 120 (ii)] In a cop winding machine having a helicallygrooved traversing drum the drum is moved axially in relation to the cop, or the cop in relation to the drum, by mechanism actuated by a feeler wheel driven by contact with the cop, the wheel being also given an automatic to and fro movement for rendering the contact between the wheel and cop intermittent. As shown in Fig. 1, the cop is held between a cupped head 9 and a collar 8 on the spindle 3 which is driven by the friction wheels 1, 2 and drives a shaft 12 having flattened sides engaging a flattened bore in the helically-grooved traversing drum 13 so that the drum is driven by and is slidable along the shaft. The drum has a single groove controlling the traverse in one direction, the traverse in the other direction being due to the inclination in which the yarn is fed from a guide 14 and being limited by a deflector 15. A boss at one end of the drum is engaged by a slotted extension of a bracket 16 projecting from a slide 18 mounted on a screwed spindle 19 and a guide bar 20; the spindle and bar being connected by arms 21, 22 and the bar being rotatably adjustable in a socket 24 at one end to vary the distance of the feeler wheel from the cop tube, and, at the other end, carrying a boss 44 which is pressed by a spring 45 against a cam 43 on a shaft 42 driven by worm gearing from the shaft 3. The feeler wheel 23 is held in engagement with the threads of the shaft 19 by a spring and when the wheel frictionally engages the cop, it is fed to the right along the shaft 19 and carries the traversing drum with it, but due to the reciprocation of the shaft the wheel does not contact with the cop except at the end of its stroke towards the left. The yarn F from the supply to the guide 14 runs under a detector lever 4 and if the yarn breaks, the detector lever tilts against a rod 5 which is moved to actuate a lever 6 which moves the wheel 2, against the action of a spring 7, out of contact with the wheel 1 to stop the machine. In a modification, the feeler wheel instead of the bar 20 is mounted for adjustment relatively to the cop tube. In the form shown in Fig. 5 the screwed shaft is replaced by a cam-actuated rack 19 gearing with a pinion splined on a shaft carrying a worm wheel 52 engaging a worm 51 on the elongated hub of the feeler wheel 23 which is mounted on a boss projecting from one end of the traversing drum 13; the pinion can be withdrawn from engagement with the rack 19 to enable the frame carrying the drum and feeler wheel to be moved back to the critical winding position. In another form the feeler wheel is mounted on a vertical shaft in the frame carrying the traversing drum and the shaft carries a pinion engaging a stationary rack. Specification 366,879 is referred to.

Patent GB-206103-A (GB)
Title: Improvements in or relating to cable-making machines
IPC: D07B3/04
Filed: 1923-02-20
Abstract: 206,103. American Chain Co., Inc., (Assignees of Conner, E. A.). Oct. 27, 1922, [Convention date]. Machines for making. - In a machine for making stranded cables, a core 33, Fig. 5, passes through a hollow spindle 59 of a stranding unit. The spindle is driven by a gear 60 from a gear 53 on a lay shaft 52 and carries flyer arms 72 and six helically-grooved dies 42, Fig. 8. Wires for the strands are drawn from spools 81, which are loosely mounted on the spindle 59 and retarded by brakes 75 on the arm 72, and pass over guide pulleys 16, 22, 28 to the dies 42 where they are first formed into helices and thereafter laid into position to form the cable. The pulleys 16 are swivelled so as to adapt themselves to the decreasing diameter of wire on the spools. The arms 72 are prevented from flying outwards by rolls 73 thereon engaging an annular track 74. The cable thus formed passes through a similar stranding unit which is driven by the shaft 52 and lays twelve more wires upon the cable to complete it. Reserve wire spools 67 similar to the spools 81 are loosely splined on a sleeve 64, which is rotatably mounted on a reduced portion of the spindle 59 and is driven through a clutch 57 mounted on a sleeve coaxial with the spindle and carrying a gear 56. Wire from a source of supply is wound on the spools 67, and when these spools are full a lever 84 is forced downwards and disengages the members of the clutch. When the spools 81 are exhausted they are removed from the spindle 59, each spool being constructed of two interlocking semi-cylindrical parts, the spools 67 are moved along the spindle to take the place of the spools 81 for supplying wire to the flyer, and the empty spools are replaced on the sleeve 64 so as to receive a fresh winding of wire from the source of supply. In a modification of the machine no provision is made for winding fresh wire on the spools, it being necessary to remove the empty spools and insert full ones by withdrawing the spindle 59 from one end of the machine. Specification 206,605 is referred to.
