Abstract
The housing of a two station machining device has thereon a stationary jaw and two movable jaws reciprocable between open and closed positions relative to the stationary jaw by a pair of spaced slides that are reciprocable in a recess in the housing beneath the work surface. A piston in the recess has one end thereof secured to one of the slides and has its other end slidable sealingly in an axial bore and counterbore in the other slide. Normally the slides and the piston are retained resiliently in first limit positions in which the movable jaws are disposed in their open positions. Hydraulic fluid under pressure is supplied to the bore in the other slide beneath the head of the piston initially to move the piston and the one slide into second limit positions in which the jaw connected to the one slide is moved to its closed position, and then to move the other slide to a second limit position and its associated jaw to be moved to its closed position. When the hydraulic fluid is allowed to return to its source, the slides and piston return to their first limit positions.
