Title: Pneumatically operated cable-slitting tool
IPC: B26D5/04
Filed: 1974-02-01
Abstract: A three-position pneumatic tool having a toggle trigger for actuating a control rod which in turn controls a pair of pneumatic check-valves. Three interconnected, tandemly arranged piston assemblies are operatively associated with an air pressure source at one end while also being operatively associated with a work assembly at the other end. The trigger is spring-biased to a location wherein the tool is in a neutral workpiece engaging position. Actuation of the trigger in one direction will open one of the pneumatic valves whereupon air pressure acts upon the upper surface of one of the pistons so as to lower or retract the tool to a workpiece insertion position. Release of the trigger permits the tool to attain the workpiece engaged or neutral position. Rotation of the trigger in the opposite direction permits the other pneumatic valve to open whereupon air pressure acts upon the lower surfaces of all the pistons so as to raise and actuate the tool to the operating position.
