Abstract
A manually operable press comprises a manually pivotable actuating lever for effecting a forward press stroke and a return stroke of a press slide. A mechanical return stroke interlock inhibits a return movement of the press before the press slide has come to a lower end position of the press stroke. A cam plate within said return stroke interlock is connected for being pivoted together with the actuating lever. The cam plate has a groove-shaped guide cam provided with a plurality of lock protrusions. A spring-biased lock pin runs along the guide cam and is adapted to run freely along the guide ram in an operational direction but is inhibited by the lock protrusions within the guide cam from running in a direction opposite the operational direction. An opening each is provided in the guide cam at the lock protrusions. Unlocking pins are provided in each of the openings. The pins are adapted to be actuated from outside the press for bringing the lock pin out of engagement with the lock protrusions thus allowing the lock pin to run in the opposite direction when the unlocking pins are actuated.
