Abstract

558,280. Actuating switches. BLISS CO., E. W. Sept. 15, 1942, No. 13002. Convention date, Dec. 26, 1941. [Class 38 (v)] Hydraulic actuation of a short-travel switch is effected through the medium of a flat flexible oil resistant diaghragm &c. 12 held by a cap 21 to a casing 18 around its marginal edges in such a way that its area, not so held, is in contact with a motion transmitting means shown as a plunger 13. A pivoted lever 14 pressed by a spring 17, has an extension S moving between a stop bar 37 and a wall 35 to operate the member 16 of the switch. As shown, the spring has two adjustments, one a screw 40 on the lever 14 and the other a housing 44 screwed into the casing, with locking means. In a modification, one adjustment only, the screw 40, is used, but the switch 15 is capable of adjustment on a swinging base plate.
