Abstract

1,137,862. Valves. N. S. F. Ltd. 2 March, 1966 [2 March, 1965], No. 8860/65. Heading F2V. [Also in Division H1] A trigger action mechanism for operating pneumatic valves or electric switches (see Division H1) controlling hand-held power tools comprises a trigger member 1 pivoted at 3 to a portion 4 of a frame 5 and urged anticlockwise by engagement with the inner surface 15 of the base 2 of trigger member 1 of the end 16 of a resilient arm 17 protruding from portion 4 of the frame. A spring 19 may supplement the force of arm 17. The surface 15 is uninterrupted or has one or more projections 18 providing for a snap feel when the trigger member is actuated. A known optional locking device may be provided. The trigger member 1 is coupled by a pin 6 to the looped end 7 of a pull-rod 8 operating the valve.
