Abstract

The moving platen (1) of the press is operated by the piston (2). To prevent unintended downward motion which could be dangerous to the operator, a rack (10) is attached to the platen (1) and meshes with a pinion (9). The pinion (9) is mounted on the shaft (7) which runs in bearings (4), (5) and (6) and carries the clutch (11), (12) and the free wheel (13) and (14). The clutch members (11) and (12) are normally engaged and the free wheel (13) (14) permits only upward movement of the press platen (1). The clutch is only disengaged when the press is switched to descend and the clutch automatically re-engages in the event of any failure in the press control system.
