Abstract

856,618. Fluid actuation of switches. BLACK, G. A. April 23, 1957 [April 23, 1956], No. 12317/56. Class 38 (5). [Also in Groups XVIII and XXXIV] Diaphragms or cylinders 7, 7<SP>1</SP>, controlled by hydraulic pressure from a colliery winding gear braking arrangement (see Group XXXIV), have pistons 9, 9<SP>1</SP> connected to a movable contact 10 to form push-pull switches to open and close contacts a, a and b, b, Fig. 5, or to sweep contacts 11, Fig. 6. In Fig. 7, the diaphragms act on a rack-and-pinion 13, 14 to rotate a cammed cylinder to close any one of a series of contacts. The diaphragms may be arranged side by side to act in the same direction (Figs. 8 and 9, not shown). Specifications 701,677, 755,878 and 797,446 are referred to.
