ABSTRACT:
A pneumatic control system for a meat trimming knife in which an annular cutting blade of the knife is rotated by a flexible cable driven by an electric motor mounted remote from the knife. An annular diaphragm is mounted in the handle of the knife and is compressed by the manual inward movement of a piston by an operator. The diaphragm is connected by an air conduit which extends along the flexible drive cable to a pressure switch mounted adjacent the electric drive motor. The switch senses compression of the diaphragm and generates an electric control signal which actuates an electric clutch which couples the output shaft of the electric motor to the flexible cable for rotating the cutting blade. The piston is maintained in a diaphragm compressed position by a hand-operated lever mounted on the handle. Upon release of the lever by the operator a coil spring returns the piston to its retracted position permitting the diaphragm to expand whereupon the pressure switch senses the change in fluid or pressure within the diaphragm which signals the clutch to disengage the motor shaft from the flexible cable to stop the rotation of the cutting blade.
