ABSTRACT:
A machine press includes a frame having an upper ram-supporting portion and a lower workpiece-supporting portion. A ram is mounted within the ram-supporting portion of the frame for upward and downward movement therein away from and toward the workpiece-supporting portion of the frame. The ram has therein a recess. The ram also has upper and lower support members extending into the recess. A lever is pivotally mounted to the frame, and the lever includes an upper arm having at a free end thereof a head which extends into the recess. The head is positioned between the upper and lower support members, such that reciprocal pivoting movement of the lever results in the head reciprocably moving the ram up and down within the ram-supporting portion of the frame.
