Abstract
A fluid piston actuated press is provided with a fixed portion, such as a die, and a plurality of movable portions, such as punches, which move reciprocally along paths which intersect the fixed portion. A plurality of levers, actuated by an actuating means, engage the movable portions to cause them to move along their paths intersecting the fixed portion.
Claims19
A press, comprising:
- (a) at least one fixed portion;
- (b) a plurality of movable portions, each of which portions is adapted to move reciprocally along at least one path which intersects said fixed portion;
- (c) a plurality of lever means, at least one for each movable portion, each for engaging said respective movable portion to selectively cause said movable portion to move along said path intersecting said fixed portion;
- and
- (d) an single actuating means engaging each of said lever means for exerting forces on said lever means to cause said movable portions to selectively move along their respective paths.

In a press having a fixed portion, a movable portion which moves along a preselected path of travel with respect to said fixed portion, and actuating means for transmitting force to said movable portion, an improved force amplification means comprising:
- (a) lever means pivotally attached to said movable portion;
- (b) fulcrum bearing means connected to said lever means for movement therewith comprising fulcrum bearing track means for allowing said fulcrum bearing means to reciprocate along an axis which intersects said preselected path of travel.
A press, comprising:
- (a) a single fixed portion;
- p1 (b) a plurality of movable portions mounted for movement along a plurality of paths;
- (c) a plurality of actuating means for transmitting force to each movable portion;
- and
- (d) a plurality of force amplification means for amplifying the force applied by said movable portions, each of said force amplification means comprising,
- (i) a lever pivotally attached to said actuating means,
- (ii) at least one bearing means attached to said lever, said bearing means reciprocating along an axis which intersects the path of its associated movable portion.
