Abstract

671. Roberts, W. T. B., and British United Shoe Machinery Co. Jan. 15. Lasting. – Relates to hand – method lasting- machines of the type described in Specification 14,453/97, and particularly to the so-called twin tack lasters of the kind described in Specifications 10,562/10, 30,020/10, 22,071/11, and 27,290/12, and consists generally in the control of the kind and number of tacks separated and fed to the tack block. The tack pot 1, Fig. 1, is partitioned to hold, for example, long and short tacks, adapted, respectively, to enter raceways 2, 3 and 4, 5, Fig. 3, each of which has a separator 6 connected to studs 8, 9, 10, 11 on bars 12, 13, 14, 15 slidable in brackets 17, 18. The raceways lead through passages 30, Fig. 1, and short pipes 31 to ducts 32, 33, 34, 35, Fig. 10, carried by a bracket 36, Figs. 1 and 10, which is adapted to be slid into position on a stud 37 and is then clamped by a set-screw 38. At their lower ends, the ducts 32, 34, and 33, 35 respectively unite into single passages 87, 88 in a removable block 41, and from these passages they pass into a tack block 40. The rods 12, 13, 14, 15 at one end contact with a cross-bar 27, Fig. 3, on a spring-pressed rod 26, which passes slidably through the brackets 17, 18 and is connected by a link 25 to a gate 23. The other ends of the rods are adapted to be engaged by the free and enlarged end 68 of a lever 60, Figs. 1 and 6, which is adapted to rock on a shaft 61 in a support 62 mounted to swivel on a hollow shaft 44. The other end of the lever 60 engages a socket in a spring-pressed hollow rod 57 within the shaft 44, being held against the upper end of the socket by a spring-pressed plunger 63. The support 62 is oscillated in the one direction by the engagement with adjusting-screws, which it carries. of a lever 67 pivoted at one end about the shaft 44 and adapted to be actuated in the one direction by the engagement with a flat on its other end of a roll on a gear-wheel driven in the operation of the machine; the return movement is effected by a spring. The lower end of the rod 57 is adapted to engage one or other of two cams 47, 48 mounted on a shaft 46 in a fork 45 on the shaft 44, the cam 47 being connected through a rod 49 to an arm which controls the position of the bunter 53, and the cam 48 through a rod 54 to an arm in connexion with the pleating-mechanism. In the position shown in Fig. 6, the bunter is forward and the rod 57 rests on the high part of the cam 48. so that the end of the rod 60 is opposite the ends of the rods 12, 13. This results in two long tacks being separated; but when the pleating-mechanism is thrown into operation, the cam 48 is moved so that the rod 57 rests on its low part, which moves the end of the rod 60 opposite the rod 12 only, and a single long tack is separated. When the bunter is moved back, the cam 47 is brought under the rod 57, and the end of the lever 60 is positioned opposite the rods 14, 15, and short tacks are separated, irrespective of whether or not the pleating-mechanism is operative. The machine is preferably timed so that the tacks are separated in the early stages of the cycle of operations, as described in Specification 669/15, while preferably the separated tacks are driven through the ducts 32, 33, 34, 35 by a blast of air, as described in Specification 670/15. In a modified construction, Fig. 7, the support 62 is provided with a bearing 79 for a disk 80 having an adjusting-handle 81 and carrying eccentrically the pivot stud 61 of the lever 60; the stud carries a block 82 slidable in a slot 83 in the lever 60. Moreover, the cam 47<1> is shaped so that its high part is level with that of the cam 48. With this arrangement, and when the bunter is forward, two long or two short tacks will be delivered, according to the setting of the lever 60, and when the pleating-mechanism is thrown into operation, one long or one short tack will be separated. With the bunter back, two long or two short tacks will be separated, according to the setting of the lever 60, and no change will be effected when the pleating-mechanism is rendered operative or inoperative.
