Abstract

A device for actuating an ejector plunger or the like on the movable carriage of a press, comprising a two-arm lever pivoted on the carriage, one arm of which is operatively connected to the plunger. The other arm has a member that runs on a track extending parallel to the line of travel of the carriage. The track is located on a member that is mounted on a stationary part of the machine and is movable in the direction normal to the line of travel of the carriage. Operating means is connected to the member to move the same periodically in the transverse direction, thereby rocking the two-arm lever and actuating the plunger. During normal operational movement of the carriage, the member on said other arm of the lever moves parallel to the track and is not affected thereby.

Dependent claims

Apparatus comprising a reciprocating carriage (15) having an ejector plunger (20) that travels therewith;

a two-arm lever (18) pivotally mounted on said carriage and movable therewith, one arm of said lever being operably connected to said ejector plunger;
operating means (12) having a flat bearing surface (16, 33) slidably engaging the outer end of the other arm of said lever, said flat bearing surface extending parallel to the line of travel of said carriage, whereby reciprocating movement of said carriage merely causes said other arm of said lever to slide along said flat bearing surface without rocking said lever on its pivot;
said operating means being movable in the direction perpendicular to said flat surface so as to rock said other arm of said lever about its pivot axis and thereby actuate said ejector plunger and
means for periodically moving said operating means.
