Abstract
838,426. Piston-rings. GLACIER METAL CO. Ltd. May 21, 1958 [May 28, 1957], No. 16948/57. Class 122 (1). [Also in Group XXII] A piston-ring designed to act also as a bearing ring is formed with spaced flanges 7, 8 on its inner surface and secured to the piston by deforming the flanges when the ring is assembled on the piston so that they are locked against undercut surfaces formed in a groove 11, Fig. 6, or grooves 12, 13, 14, 15, Figs. 4 and 5, provided in the piston. The ring is placed in position with the flanges 7, 8 partly in the groove or grooves and pressure is then applied to the outer face of the ring to deform the flanges and key the ring to the piston. As shown in Fig. 2, the ring is a composite one formed by a steel backing-ring 5 and a bearing layer 6 preferably of bearing material such as copper-lead, bronze, or an aluminium alloy. Alternatively, the ring may be made entirely of a bearing metal or alloy. In a modification, Fig. 3 (not shown), the flanges 7, 8 are chamfered towards their free ends.
