Abstract: 13,621. Telfer, J. C. June 18. Lacing-fastenings.-Relates to a machine for separating and setting lacing-fastenings made in strips or gangs, such as described in Specification No. 2546, A.D. 1902, the final clinching and bending being such as is described in Specification No. 25,937, A.D. 1902. At the forward end of the frame 1, a sliding punch bar 11, provided with a series of punches, is operated by pitmen 10. The punches operate against a slotted dieplate 23, attached to a block 21, mounted on a fixed channelled plate 16. Spring clips are arranged over the plate 23 and block 21 for holding and ejecting the waste strips of the gangs of fastenings, the waste strip being tilted by a stud so as to fall clear away when ejected. The blocks 21 and plate 16 form guidechannels for the separated fastenings, spring stops 39 being set in the channels to stop the passage of the fastenings until the required movement. The gangs of fastenings 31 are placed on the oscillating table 26 carried by arms mounted on shaft 98 so as to be brought into position for severing. The plate 16 is provided with sockets 90, Fig. 2, in which engage pins on pivoted telescopic guides 88 for the fastenings. The guides are pivoted at the rear to blocks 72 mounted on slides 54, and may be moved to any desired angle. The slides form either a single layer or a double layer 52, 54, each pair being separated by a variable space bar. The elements of each pair are separated by washers 57, and the lower ones 52 are provided with cam locking-levers 58. The slides are mounted on a table 49 and work under transverse bars 55, the forward and backward position of the slides being regulated by screws 133. The guides are set so as to bring each fastening to position at right-angles to the shaped edge of the stock to which they are to be secured. The fastenings are received and held by jaws 77, Figs. 7 and 8, between which is mounted an eccentric pin 76 for regulating the position of the fastening as regards the edge of the stock. The jaws are mounted on the blocks 72, and are operated by V-cam slotted sliding pieces 79 acting on heel-pieces of the jaw levers. At the required moment the hammer block forces the tangs through the stock, and the clinching takes place as described in Specification No. 25,937, A.D. 1902. The anvil block may be rigidly mounted or may be secured against a resilient backing of india-rubber &c. A work-table 87 with adjustable setting-guide 93 may be employed. The shaft 98 carrying the operating-mechanisms is provided with a sleeve 103, which carries a second divided sleeve with spring sliding locking-rods; one of these is bent to a hook shape so that motion in one direction operates both rods simultaneously. The sleeve 103 is connected through a bell-crank lever and links with a lever 112, Fig. 2, which bears against a cam 120 on the driving-shaft 9. The lever 112 is pivoted in a slot, and is held up by a spring 115 while its lower end is connected to the treadle lever ; it also carries a catch for engaging with the bell-crank lever 123, Fig. 18, for operating the clutch detent 119 of the driving- wheel 116. The driving-wheel is arranged to be in connection with the apparatus for one revolution only for each depression of the treadle. The driving-wheel is provided with a spring sliding block 117 having a locking-shoulder 117<d>, by which it is held out of engagement with the wheel 120, when forced to the right, and the catch 119 is allowed to rise. The block 117 is forced to the right by a cam on the completion of one revolution, and is only released when the depression of the treadle causes a tripping-device 126, on a bell-crank lever 123, and catch 119 to engage.
