Abstract
234,671. Patrick, H. H. Aug. 6, 1924. Detonator apparatus; hand levers; lamp signals; detonating signals.- The carrier-chain 36, Fig. 6, is actuated by sprocket wheel 35 on a shaft 32 carrying a bevel wheel 31 which is continuously rotated from a reciprocating shaft 6 by loose bevel wheels 7, 8 carrying pawls 9, 10 engaged by opposed ratchet wheels 11, 12 secured to the shaft 6. The shaft 32 is journaled in plates 2, 3, Fig. 3, carried by longitudinal frames 1 which also support a plate 4 for a lamp 61. An arm 51 on the shaft 6 reciprocates a rod 53 carrying a frame 57 provided with red and green glasses 58, 59. Spring-pressed pawls steady the motion of the bevel wheels 7, 8, while a stop arm is fixed to the shaft 6 which carries a weighted lever 13 coupled by a wire or rod 14 to a hand lever 15. The lever 15 has a slide 24 with bevelled ends 27 engaging notches 19 in the quadrant 18, the lever being movable in one direction only until the slide is reversed by its handle 23. Each detonator 42 has a wire loop 43 which may engage a pin 50 on the carrier 39 and is secured by a bolt 45 and plate 47. The travel of the chain 36 may be arranged to place a detonator over the line at every movement of the lever, or at every two movements. Several machines may be place side by side and operated by one lever.
