Abstract: 2624. Cheney, F. L. Feb. 6, 1909, [Convention date]. Setting lacing-hooks.-A machine in which the hook-holding die and anvil are both reciprocated vertically and the hooks are positively fed to the die by a plate engaging a number of hooks, has a driving-shaft 2, Fig. 1, journaled in a frame 1 and driven by a pulley 4 through a clutch 7; this shaft can be stopped quickly by a brake-lever 11 having at one end a cam roll 13 bearing against a cam 14, on the clutch, the rotation of which causes a shoe 15 at the other end to set firmly against a main cam-disk 16. The hook-holding die 18, Fig. 11, is reciprocated through a lever 19 by a cam-groove 17 on the disk 16, which also carries a cam 24 for pressing down the anvil 25 through a cam-roll 29a and a lever 27. The anvil is returned by a spring 29, and its stroke is regulated by a screw 27<a> the collar of which adjusts the position of the cam-roll 29<a>. The hook die 18 has an undercut flange 30, Fig. 8, to receive the hook which is held therein by a spring-pressed finger 35. Lacing - hooks, feeding.-The hooks are fed from a raceway on to a plate 75 and thence to the die 18 by a feed-plate 85, Fig. 4, having fingers 86 to engage the hooks. The plate 75 has a projection 76 forming a continuation of the raceway, and has springs 78 to hold the hooks while the feed-plate 85 is making another stroke. An adjustable spring 83 holds the hooks on the raceway in position to be engaged by the feed-plate. The plate 85 is screwed to a bed 88, which is moved longitudinally on its dovetailed tongue 89 through a block 90, which is moved in a similar groove in a direction at right-angles to that of the bed 88. Motion is imparted to the bed 88 and block 90 by cams through suitable connexions. Work-feedi,ng mechanism.-The work is fed forward on a fixed table 38 by a feed-block 44, Fig. 14, which has corrugations 45 to engage the work, and is pressed down thereon by a lever 50, Fig. 1, actuated by a cam 49 and bearing on the supporting-member 47, Fig. 11, of the block 44. The member 47 has a hole 47<a>, through which the riveting-plunger reciprocates, and is carried by a square stem 48 surrounded by a spring 48<a>, Fig. 11, arranged to hold the feed-block normally out of engagement with the work. The block 44 is moved longitudinally to feed the work by a rod 54 having a forked end 56 engaging a pin 57 on the block; the rod 54 is fulcrumed at 55 and, at its other end, is moved to and fro in a guideway 58, Fig. 1, by a crank-pin 59 and connexion 60. The pin 59 is fixed in the face of a gear 61 which is rotated from the main shaft throngh the gears 62, 63, 64. Spacing-mechanism.-To vary the spacing of the hooks, the amount the work is fed forward is adjusted by shifting the fulcrum 55 which is connected to the lower end of a lever, the upper end of which is formed as a handle and pointer moving over a scale to determine the spacing. The lever and fulcrum can be locked in any desired position. Work - holding mechanism. - A presser - foot 101, Fig. 1, operated from a cam 102 through a lever 103, holds the work against the table.
