ABSTRACT:
Apparatus for feeding bar stock through the chuck of an automatic lathe. The apparatus is moved laterally by the turret to form shallow notches in the surface of the bar stock. The notches in the bar stock are gripped during longitudinal movement of the turret to advance the bar stock into the work area. A pair of cutting elements are adjustably located on one end of the apparatus to grip bar stock of various diameters. Guide blocks having interchangeable bushings to accommodate bar stock of different diameters are also disclosed for supporting the bar stock for rotation by the chuck.
