Abstract
136,349. Cameron, M. H. Jan. 24, 1919. Punching; punches. -In a machine for punching holes in girders of T, I, or other section, or in plates, the work is supported on a table made in one piece and having a vertical slot leading to an enlarged recess k. The punches n, o are eccentrically disposed on their shanks f, g, so that the distance between the punches can be adjusted. As shown, the shanks are retained in one of two positions by screws p. Each punch shank is slidable in a socket in the tool-slide d, and the punch is made operative or inoperative by a transverse sliding bar h which is moved to allow or prevent movement of the shank in its socket. The holes in the dies l, m co-operating with the punches are eccentrically placed, so that the distance between the holes may be adjusted to correspond with that between the punches.
