Title: Improvements in or relating to shoe upper shaping machines
IPC: A43D13/00
Filed: 1922-03-15
Abstract: 199,123. British United Shoe Machinery Co., Ltd., and Roberts, W. T. B. March 15, 1922. Pulling-over. - Relates to pulling-over machines of the type described in Specifications 7005/00, 12304/03, C7154/11, and 22193/14 and consists in improved means for slitting the edges of the upper. A flap is formed at the toe by a pair of knives 1, Figs. 1 and 6, guided on the sole support 4 and' operating in the gap in the toe pincers 5. On each side pincer casing slides a knife 42, which slits the upper in proximity to the side pincers. The knives are actuated from the side-clamp cam-slide 20, Fig. 2, described in the prior Specifications, which carries a pawl 21 adapted to engage the tail of a gear segment 18 and thus turn a shaft 14 connected by bevel gearing 13 to a flexible shaft 9 driving pinions engaging racks operating the knives 1. The knives 42 are operated by links 35, Fig. 1, with ball ends, the upper ends being depressed by arms 34 on a shaft 33 driven from the shaft 14 by helical gears. The pawl 21 is disengaged when it reaches a cam 28, Fig. 2, and thereon the knives are returned by a spring 15 on the rod 14. A catch is provided to retract the pawl 21 when slitting is not required.

Abstract: 550,565. Elastic threads. SHEPHERD, T. L. July 3, 1941, No. 8394. [Class 70] Rubber or other elastic threads, tapes, ribbons &c. are rendered inelastic by applying 'to the thread &c. while stretched a coating of glue, gelatine, starch &c. and allowing the thread to relax to its rest length before the coating is set. The thread may be first covered with textile threads such as cotton, silk, rayon, worsted &c. Elasticity is restored by treatment in a scouring bath. The thread is useful in sewing elastic or non-elastic fabrics. Elastic threads T, are stretched between rollers 3, 4, passed under rollers 6 immersed in a size bath, over steam-heated rotating cylinders 9 to takeoff rollers 11 rotating at the same speed as the rollers 4. The threads are collected on bobbins 12 rotated at a speed which allows the threads to relax. Two or more coatings may be applied to obtain complete inextensibility. The coatings may be applied to the thread before it enters the hollow spindles of the machine for covering it with textile threads. Specifications 423,997, 533,777 and 545,882 are referred to.

Filed: 1916-06-14
Abstract: 103,936. Root, C. F. June 14, 1916. Tripping and throw-out arrangements. - A safety-device and tripping-mechanism for printing presses is so arranged that, when a guard is moved by an obstruction such as the operator's hand, the plunger makes a short stroke at a reduced speed, but does not stop, jarring being thereby obviated. In the press shown in Fig. 1, a platen 4 and bed 3 both rock and come into contact in the plane of a yoke-shaped guard or controller 31 which telescopes the platen 4. A driving-link 11 is connected to the bed 3 by a pair of toggle-links 18, 19 normally held in line against a stop-pin by a spring 26<1>. The guard 31 moves vertically, being guided by a slot 33 engaging the end of a T-shaped lever 36. When the guard 31 is moved in either direction by an obstruction, the lever 36 is rocked and raises a lever 40 by either of two pins 37, 38. The lever 40 raises the end 45 of a lever 44, causing the other end 47 to release a gravity pawl 48, which then engages teeth 54 on an arm 51, holding it stationary for the remainder of the stroke of the link 11. This collapses the links 18, 19 as shown in Fig. 9, and stops the direct actuation of the bed 3, which, however, is advanced indirectly to a less extent by teeth 23, 24 formed on the link 19 and on the end of a rocking arm 25. On the return stroke, if the obstruction is removed, the guard is returned to its normal position by springs 43, 46, and the hooked end 55 of the arm 51 lifts the pawl 48, so that it is caught by the lever 44. An arm 59 on the guard can be turned into the path of the platen 4 so as to operate the tripping-mechanism at every stroke if desired.
