Abstract

448,260. Pistons. BOHN ALUMINUM & BRASS CORPORATION, 2512, East Grand Boulevard, Detroit, Michigan, U.S.A. Dec. 4, 1934, No. 34807. Convention date, Dec. 5, 1933. [Class 122 (i)] In pistons in which the bosses are connected to the head by struts 17, 19 of U-section the bases 17 of the U-members are spaced outwardly from the chordal webs 12 supporting the bosses. The side ribs 19 diverge as they approach the head. A central web 18 may connect the bosses and the piston head. The skirt may be of oval section with the smaller axis beneath the bosses ; expansion on this axis under heat being assisted by inclined ribs 22 extending downwardly from the bosses on the webs 12. Each of the webs 12 is provided with an L-shaped opening 23. Each thrust face is recessed along curved lines which converge upwardly. A T-slot may be provided in the thrust face and the oil holes in a scraper groove 25 are spaced wider apart above this slot for greater strength. Specification 436,066 is referred to.
