Abstract

418,680. Drilling non-circular holes. MASON, W. H., 59, Kenwood Road, Stretford, Manchester. May 1, 1933, No. 12574. [Class 83 (iii).] A device for drilling non-circular holes has a rotating bit and a cutter mounted on a slide which reacts to a cam through an adjustably pivoted lever. The cutter B, supported against a backing bit A, is carried by a slide C, reciprocated against spring pressure by the lower end of a pivoted arm E. This arm is pivoted on an adjustable plate H, movements of which are guided by a cam-projection J, the plate being fixed in its adjusted position by a wing-nut K. The upper end of the arm E is oscillated by a cam-piece F shaped correspondingly to the hole to be cut and held stationary during rotation of the other parts of the device. Adjustment of the plate H alters the effective movement of the arm E with respect to the cutter-slide and thus allows differently-sized holes to be cut with the same cam.
