Abstract: 16,222. Saville, R., and Fieldhouse, Crossfield, & Co. July 13. Making labels.-Relates to the general construction of machines for stringing tags or labels, for instance, of the kind described in Specification 4691/09. Tags are piled in a holder 5, and are fed by a plate 7 of usual construction, which is reciprocated by a spring 8, a lever 9, and a cam on a countershaft 2. A needle 12 is reciprocated vertically by a lever 18 and a rod 19, and works through a hole 20, beneath which the eyelet of each tag is situated after it has been fed from the pile, in which position the tag is clamped by a foot 13 rocked on a shaft 14 by a rod 16. As the needle is rising, nippers 22, Fig. 3, seize the depending string and draw a length from the ball thereof. The jaws are pivoted at 29 to a slide 28, and are connected by links 24 to a bar 25, which is reciprocated by a lever 67 and a cam on a vertical shaft 3. As the bar 25 moves outwards, the jaws are first closed on the string and are then moved bodily with the slide 28, and as the bar returns, the jaws are opened before they return. After the needle has descended, a looper 33, pivoted to a lever 31 rocked by a cam on the shaft 2, is caused to carry the string above the level of the tag by an arm 37, a roller on which runs on a camplate 39. As the looper rises, its arms are opened out by a pin 34 on one arm riding on a cam 36 on the arm 31 in known manner. A gripper which comprises a fixed jaw 40 and a jaw 41 pivoted to a slide 42, passes through the loop and seizes the double string, which it then draws through the loop. The slide 42 is reciprocated by a link 44, a lever 47, a rod 48, and a crank 49. Arms 50, 51 on the jaw 41 contact with stops to open the jaws of the gripper against the action of a spring 55. The stop at the forward end comprises an arm 52 pivoted at 53 and rocked by a cam 54 on the shaft 3. When the gripper has drawn the double string through the hole 20, the single string which follows is severed by cutters, one of which is reciprocated by a link 58, a lever 59, a rod 60, and a cam 61. When the double string is being drawn through the loop, it is depressed by a projection on a shaft 77, Fig. 1, which is rocked by an arm 78, a rod 79, a lever 80, and a cam 81, to prevent the loop from catching on the string, and the string which is drawn through the eyelet of the tag is kept vertical by a pin 62, Fig. 3, projected into its path by a lever 65 and a link 66 connected to the lever 67, to prevent it from tearing the eyelet. As the gripper withdraws, the string slips through its jaws until the foot 13 releases the tag, which is then drawn between rollers 68, 69 and dropped down a shoot 71 on to a conveyer band 72. The roller 68 is recessed to allow the gripper to pass it, and is carried by swinging arms 70. The conveyer band is moved intermittently by the rack - and - pinion mechanism of a drum 74 coupled to the lever 47 by linkage 75. According to the Provisional Specification, the free end of the string may be held by a spring catch which works with the needle.
