ABSTRACT:
A toggle press having a lower platen assembly constructed to provide a convenient working level for the platen in its open position. The fixed axis of the toggle linkage is mounted immediately adjacent to the ground and the actuator for the toggle linkage is inclined in the direction downwardly progressing away from the toggle actuating axis. The press is constructed with a beam which includes a base plate, this base plate having an extension upon which the fixed pivot of the toggle linkage is mounted, below the neutral axis of the beam. Additional structural features enable compensating deflection and self-alignment of the toggle bearing under load.
