Patent ID: 7267383

Claim:
A method for detachably securing a gripper tool to a movable crossbar of a transfer press, which gripper tool has a first saddle and a second saddle disposed with spacing between them and with them is brought into engagement with a first bearing and a second bearing mounted on the crossbar and is locked in a defined engagement position, wherein the gripper tool, in an inclined position relative to the center longitudinal axis of the crossbar, is introduced, with at least one protrusion of rounded longitudinal section or tapering in wedgelike fashion, on the first saddle into a correspondingly rounded or V-shaped narrowing recess in the first bearing and is then pivoted with the second saddle toward the crossbar, whereupon wedge faces on the second saddle and on the second bearing press the protrusion by the force of gravity axially against a wall of the recess, and then the second saddle is locked to the second bearing.
