ABSTRACT OF THE DISCLOSURE A powder compacting press provided with a mechanical toggle mechanism for reciprocating a ram disposed above the die supporting the table of the press, the pivotable support for the ram toggle upper connecting rod being connected to the movable member of a fluid cylinder. Fluid pressure in the cylinder urges the movable member to an extent limited by abutments, thus tending to displace the ram in a direction toward the table. The full force exerted on the ram by the toggle mechanism causes retraction of the fluid cylinder movable member until engagement of a second pair of abutment means cause the full force developed by the toggle mechanism to be exerted on the ram. The same cam is used for actuating the ram irrespective of whether the ram is used for clamping an anvil in position over a die cavity when the press is used in an anvil pressing mode, or for reciprocating upper punches, when the press is used in an opposed punch operating mode.
