GA?-4?-6113 PRESS HAVING OVERLOAD RESPONSIVE SLIDE SHUT HEIGHT ADJUSTING MECHANISM Abstract of the Disclosure The reciprocating slide of a mechanically driven press has a ball and socket type interconnection with the connecting rod of the press drive mechanism. The socket component of the interconnection provides a rotatable adjusting screw threadedly interengaged with an annular piston received in a cylinder component on the slide. A locking nut threadedly engages the adjusting screw and is rotatable relative thereto and to the piston to lock the adjusting screw against displacement relative to the piston. During normal press operation the locking nut is biased against a shoulder on the cylinder by hydraulic fluid under pressure in a variable volume chamber between the piston and cylinder components. In response to an overload on the slide, a pressure responsive relief valve releases hydraulic fluid from the chamber and enables relative movement between the piston and cylinder components and thus between the slide and connecting rod.
