Abstract

501,713. Making pistons. MAHLE, H. June 21, 1938, No. 18372. Convention date, June 25, 1937. [Classes 83 (ii) and 83 (iv)] Pistons with longitudinal ribs 3, Figs. 2 and 3, extending up to the piston head and serving for forming and reinforcing the bearings, are made by first pressing a block of metal with the ribs 3 and then expanding same at 8 by forcing mandrils into the sides to form the bearings. An internal die shown in chain lines is employed. The external die may be the same for the first pressing operation and the piercing operation.
