Abstract

The safety device is for a mechanically controlled press has a piston rod, parallel to the drive shaft, housed in a bore in the frame. The rod presses via a boss or solid ring on the frame on a sliding part, positioned specially relative to the clutch lever (1i). Should the clutch lever break and come out, the piston rod, pushed by a spring, presses on the sliding part to move it to engage in a hole in a rotating ring. This fixes the rotating ring relative to the frame.
