ABSTRACT:
A forging press having a mechanical load transfer mechanism in the form of a motion and force multiplying lever arrangement and linkage between a press load beam and the press ram so that forces applied to the load beam through the tooling from the ram are transferred to the ram to aid the ram in its downward forging movement. A suitable lost motion linkage is provided which permits the ram to move away from the load beam after the load beam has stopped in its upstroke position to effect the removal of a formed article.
