ABSTRACT:
A hydraulically actuated power cylinder reciprocates a driver to exert a compressive force to upset a rivet with the power cylinder's movement being made to correspond to the movement of a pump cylinder by a fluid connection therebetween. The pump cylinder's movements are mechanically actuated according to a programmed cam and actuation is made to occur only during the riveting cycle by a control circuit operating a clutch and brake with the circuit inhibiting operation upon the sensing of a malfunction.
