ABSTRACT:
A press for assembling a fastener or the like to a plate or the like comprises a frame and an anvil assembly carried by the frame. A linkage mechanism assembly is carried by the frame and includes two links. A ram assembly is operatively connectable to one of the two links. A first fluid operated cylinder and piston assembly holds the ram assembly in a raised position. A first switch terminates the flow of fluid to the first cylinder, thereby permitting the ram assembly to drop. A second fluid switch is activated after a sufficient drop of said piston to energize a second fluid operated cylinder and piston assembly for extending and retracting said links, and thereby move one of said links into force transmitting relationship with said ram assembly, to thereby cause said ram assembly to move forcefully down toward the fastener for the purpose of installing the fastener into the plate.
