ABSTRACT:
The two sets of ball bearings which support an inverted, generally U-shaped slide on the base member of the assembly are carried in the leg sections of an inverted, generally U-shaped ball cage which is positioned between the base member and slide. A piston which is reciprocated by compressed air in a bore in the base member, is connected to the two leg sections of the ball cage by a dowel pin, whereby reciprocation of the piston is imparted to the ball cage and the bearings supported therein. A cylindrical copupling pin which is rotatably mounted intermediate its ends in a slot in the central portion of the ball cage, projects at opposite ends thereof slidably and rotatably into registering, diagonal grooves formed in confronting surfaces of the base member and slide, thereby coupling the cage to the slide and base member for movement in unison by the piston.
