ABSTRACT:
A fluid piston actuated press is provided with a lever arm having multiple bearing means for transmitting and amplifying the force exerted by a piston to the movable parts of the press and work piece. A novel fulcrum bearing is provided which ensures that frictionally induced shearing forces are counteracted. This is achieved by allowing the bearing to reciprocate along an axis which is acute with respect to the stroke axis. Additional means are provided to adjust the degree of amplification and stroke of the movable part without altering the stroke of the fluid piston. A novel arrangement of component parts is described which allows easy accessibility to the work area and great flexibility of application. An alternate embodiment of the present invention further describes a multiple piston actuated press provided with a plurality of lever arms and bearing means for transmitting and amplifying the forces exerted by said pistons to movable parts of the press, which parts are mounted to reciprocate along transverse axes.
