Abstract

719,846. Actuation of switches. ROCKWELL MANUFACTURING CO. Sept. 1, 1952, No. 21968/52. Class 38(5) [Also in Group XXII] A switch mechanism for a drilling &c. machine comprises a snap-over arm 48 to complete or break a circuit between wires 52, 55. The circuit is closed as the drill advances together with a rod 64, advance of the drill causing pressure fluid to depress a piston 75, 69, the fluid entering through a passage 67 and a gland 70. At the forward position of the drill, the fluid pressure falls and a spring 76 causes the piston to jump upwardly against a plunger 85 and open the switch. The switch is reset at the end of the drill return movement by the rod 64 depressing a plunger 65.
