Abstract
572,619. Grinding. UNITED AIRCRAFT CORPORATION. Sept. 17, 1943, No. 15295. Convention date, Oct. 17, 1942. [Class 60] Piston rings are lapped to produce thereon a crowned cylinder bearing surface, as shown in Fig. 3, by reciprocation of the rings 10 in a lapping-cylinder 12 by means of a carrier 14, positioned at an angle other than a right-angle to the axis of the cylinder, or mounted in. grooves on the carrier set obliquely to the axis of the cylinder, the carrier being rotated intermittently so that the rings change their position with respect to the cylinder wall. The carrier is mounted on a rod 32 swivelled at 30 to the piston-rod 20 of a piston 18, which is reciprocated by pressure fluid in a cylinder 16, and guided by a cross-head 24 having guide rods 22 sliding in holes in the cylinder head 26 and flange 28. The rod 32 carries a plate 42, on which is journalled a ring 41 connected by a ball-and-socket joint 40 to one end of an arm 34, which is supported at its other end by a universal joint 36. The ring 41 carries a pawl 44 engaging a ratchet 46 on the plate 42, backward rotation of which is prevented by a detent, so that as the piston 18 reciprocates to move the rings axially of the cylinders, the arm 34 &c. causes partial rotation of the rod 32, and thus also of the carrier 14 and the rings 10.
