Abstract

513,407. Lapping piston rings. CROSS, R. C., and CROSS MANUFACTURING CO. (1938), Ltd. May 24, 1939, No. 15433. [Class 60] [Also in Group XXII] Apparatus for lapping piston rings comprises a holder 4 with annular grooves for receiving rings 1 so that they resiliently protrude with their outer surfaces in contact with the cylin. drical inner working surface 8 of a lapping tool 7. The holder and lapping tool are of the same size as the piston and cylinder with which the finished ring is to be used and in the process of lapping are given a relative reciprocating and rotary movement. Specification 486,388 [Group XXII], is referred to.
