Abstract

238,075. Patrick, H. H. Aug. 6, 1924. Detonating signals; hand-levers; detonator apparatus of the chain type comprises a plate frame 2 carrying chain sprockets 61, 62, sprocket 61 being secured to a ratchet wheel 21 engaged by spring pawls 17, 18, pawl 18 being carried in a frame 20 fixed to the frame 2 and pawl 17 being carried by a lever 13 spring pressed at 25 and actuated by the armature 32 of an electromagnet 33 energized by a battery and hand switch at a distance. Each detonator 68 has a wire loop 69 and extension 70 secured by bolt 71, plate 72 and pin 75 to a member 64 carried by the chain 63, as in Specification 234,671. A double actuation of the lever 13 is required to carry a detonator from position J to position 68<x>, while stops 22, 23 limit the movement of the lever. The frame 2 is provided with feet to bring each detonator at position 68<x> over the rail head. The hand switch comprises a lever 46 with insulated handle 47, pivoted at 45 and moving between two contacts 48 on a frame comprising two plates 36, 37 of ebonite or other insulation, the lever 47 in its movement passing through the contacts to position I.
