Abstract: A workpiece holder comprising a base having guide walls defining a workpiece pathway and a linear pushbar displaceably mounted to said base to extend laterally toward the pathway. The pushbar includes an upper wedge-shaped arm adapted to mate with a wedge-shaped member fixed in a substantially fixed position with respect to said base and a second locking arm adapted to engage the edge of a workpiece at the workpiece station. The upper arm of the pushbar extends over a locking plate resiliently supported above the base so that insertion of the wedge depresses the locking plate upon the workpiece. A work stop is displaceably mounted at an end of said pathway to align the workpiece at the workpiece station before it is clamped in place for a machining operation.
