ABSTRACT:
A vertically moveable upper receiver is suspended on the machine by spring means and has a central vertical cavity therethrough. A pair of opposed springs bias together jaws in the receiver having aligned notches therein which receive the part. The upper tool or punch descends through the cavity, engages the part, drives it out of its notches and downward against the inward pressure of the jaws, the receiver descending through this operation, and the part arrives precisely centered at the setting locus.
