Abstract: 450. Augustin, L. Jan. 7. Setting lacing-hooks.- A machine for setting lacing-hooks comprises a base 1, Fig. 1, bearing an arm 2, bracket 3, and hangers in which are journaled the power shaft 4 and countershaft 5. Setting - mechanism.-The shaft 5 carries an eccentric 8, about which is clamped the strap of a pitman 10, pivoted to one end of a rock-arm 11 to operate a plunger 25 for setting the lacing- hooks. The plunger rod 25 firmly holds a spindle 28 carrying a yoke 27, Fig. 7, in which is pivoted a head or holder 26 comprising a block having countersunk recesses 29 and narrow openings 30. The lacing-hooks are fed one at a time through each opening 30 into a recess 29, the thin wall of which fits between the top of the hook and its shank and acts as a plate to receive the thrust of the riveting-tool. The head 26 is rotated, when a hook has been set, by a pivoted spring-pressed tongue on an arm 38. The tongue has a bevelled point and an abrupt shoulder, which engages with the recesses 29 on the downward movement of the plunger, a star-wheel and catch preventing reverse rotation. To prevent the hooks from being shaken from the holder, a light yoke 41, Fig. 8, carries a pin 42 which works in a slot 43, Fig. 7, in the yoke 27, the lower end of the first yoke riding over the books and by its weight serving to hold them in place. Lacing - hooks, feeding. - On the bracket 3 is mounted a magazine 12, in which rotates a shaft 13 carrying a wheel 14, which picks up the lacing- hooks and delivers them to a raceway 15. The shaft 13 is rotated by a ratchet disk 19 fast on it and driven by a pawl 24 on a bell-crank 23, which is freely pivoted on the shaft 13 and is actuated by the rock-arm 11. The hooks are fed from the raceway one at a time by a small wheel 31, Fig. 1, having teeth at distances around its circumference equal to the distances between the hooks. The wheel 31 is rotated by step-by-step mechanism similar to that for rotating the selector wheel 14, the bell-crank in this case being rocked by a cam 35 through arms 34, 33. The hooks on the lower end of the raceway are kept separate by means of a small plunger having a lug to engage with the wheel 31 and a wedge-shaped blade to pass between the heels of the hooks. The plunger is moved downwards against a spring by the teeth of the wheel 31. To ensure the hooks travelling down the raceway, a small hammer 60 is held by a spring 64, Fig. 39, against its lower edge. The hammer is actuated by a pin 62 on a rapidly revolving disk 63 coming against an arm 61. Driving-mechanism.-The shaft 5 is driven from the shaft 4 through a pinion 7 and a gear 6, which has a chambered hub 44, Figs. 32 and 32, adapted to receive the hub 45 of a clutch 46 ; a rotatable pin 48 on the latter hub engages with notches 47 in the former one, and is held in engagement by means of a spring-pressed lever arm 50. To stop the machine, the arm 50 is acted on by a catch 52, Fig. 22, connected by links 54, 55 to a treadle 56. The clutch is so arranged on the shaft that, when the machine is stopped, the setting-mechanism 26 is in its topmost and inoperative position.
