Abstract

471,212. Operating mechanism for photographic shutters. DUNLOP RUBBER CO., Ltd., WRIGHT, J., and TREVASKIS. H. March 12, 1936, No. 7454. [Class 98 (i)] A device for operating camera guns has a chamber containing a piston displaceable by fluid pressure and a slot through which projects a trigger operating member connected to the piston. The body 1 has a cylindrical air chamber 2 containing a piston 3. The opposite ends of the chamber 2 are closed by threaded plugs 4, 5 which limit the movement of a U-shaped member 6 connected to the piston 3. The end of the member 6 is formed with a trigger operating portion 14, which projects through an inclined slot in the wall of the body 1. Compressed air is admitted through a flexible pipe 7 to an air channel 8 and from there via an inclined channel 9 into the air chamber 2. When the air is admitted, the piston is moved and the trigger 16 of the camera moved by the member 14. The air is exhausted by release of a control valve and the piston is returned by the spring loaded trigger 16. In a modification (not shown), the trigger operating member is connected by a cable wire to a further operating member which is loaded by a tension spring.
