Abstract

310,921. Bohn Aluminum & Brass Corporation, (Assignees of Nelson, A. L.). May 3, 1928, [Convention date]. Pistons.-A piston is ground oval by providing, during grinding, a less firm support at the parts which are to have the greater diameter, so that the parts spring inwardly and are ground to a less extent. The piston, consisting of a head 17 and a skirt 18, is mounted on a rotating centre 11 having a driving-pin 16, the centre having cut out parts 20, 21 to allow the piston to spring, and a spring-pressed centre 14 supporting the piston at its closed end. Instead of using a centre with cut out parts, the centre 11 may be circular, and the piston has ribs at its open end adapted to rest on the centre, the ribs having gaps so that the piston is unsupported at the gaps.
