Abstract
The fluid-pressure actuated press is mounted on a column structure. It has a ram, a piston, and an associated piston rod. The free end of the piston rod reciprocates downwardly. A support adjustably mounts the ram on the column structure. A lever bar has a proximate free end in engagement with the free end of the piston rod. The distal end of the lever bar is pivoted about a fixed fulcrum carried by the support. A chuck rod is slidably mounted relative to the support along an axis which is parallel to the axis of the piston rod. The chuck rod is pivotably associated with the lever bar at a point intermediate its ends, whereby the reciprocation force on the piston rod is multiplied by the lever ratio to cause reciprocation of the chuck rod with the multiplied force.
