HEX-HEAD ALIGNER FOR SCREW SLOTTING MACHINES

This aligning device is designed to insure slotting the heads the long dimension from point to point diametrically of the head using opposed flats on the heads for such alignment. Two legs pivotally connected together at one end are disposed in straddling relationship to the space between the dial and a fixed slide plate in substantially tangential relationship to the dial and are spring pressed toward one another to provide sliding aligning contact of a longitudinally extending rib on one leg, first with a flat on one side of each head and later similar engagement of another rib on the inner side of the other leg with a flat on the opposite side of the head shortly before the blank arrives at the first of two spaced coplanar saw blades for the slotting of the head diametrically thereof in the turning of the dial. Means is provided for adjusting the spacing of the legs to suit different sizes of heads.
