Abstract

602,367. Punching. DAYTON ROGERS MANUFACTURING CO. Feb. 21, 1944, No. 32355/46. Convention date, Aug. 18, 1942. Divided out of 602,308. Drawings to Specification. [Class 83 (iv)] Control means for the operating mechanism of a punch press includes a pair of spaced electric contacts adapted to be bridged by the work or by a work-carrying jig, whereby the press is automatically set in motion when the work is inserted between the punch and the die. The insertion of the work also energizes an electromagnetic work-holder which holds the work in operative relation to the punch during the piercing operation. The press is fully described in Specification 602,308.
