Abstract: 664,277. Making piston-rings. TAGLANG, K. March 24, 1949 [Dec. 29, 1948], No. 8112/49. Class 83 (ii). [Also in Group XXVI] A piston-ring is made by milling a slot 2 radially through a ring, then making a cut from each side face into the slot and then imparting permanent enlargement or reduction of its diameter by mechanical or thermal treatment. A ring 1, Figs. 4 and 5, is turned accurately to the size required internally and externally and a slot 2 is milled radially at the middle of its width. The ring is then severed by staggered cuts 3 in planes passing through the axis. The ring may be enlarged by hammering internally and externally or rolling if of bronze or cast iron &c. or by heating while expanded if of cast iron. The ring is made gas-tight by filling pieces 4, 5, Fig. 7, of steel, bronze, &c inserted in the slot and secured by rivets 6. Instead of using two cuts 3 the ring may be severed by a single cut 3, Fig. 9, which may be inclined, and made gas-tight by a single piece 5 riveted in the slot in one end of the ring and engaging that in the other. In a modification, a cut 3, Fig. 10, is made from one face and a broad cut or two spaced cuts from the other, an insertion piece 7 being riveted in the gap thus formed. If a contracting ring is required, wide cuts 12, 12', Fig. 12, are made in severing the ring and this is contracted by treatment.

The major inside diameter of the sleeve may also be reduced, so as to produce a substantially cylindrical part on the sheath, by pulling out the corrugations with the apparatus shown. Tensioning forces are applied to the sheath by plates 3 and transmitted through moulded metal or plastics clamps 1 which are secured to the sheath by clips 2. The effectiveness of their circumferential clearance as a heat barrier may be increased by evacuating the space and/or introducing tubular, or a container of granular, insulation. Alternatively, cooling fluid may extract the heat of welding, e.g. oil or gas may be circulated on each side of a tube inserted in the space, or an annular tube may be used which has a closed end and is divided by an intermediate wall for use with water as a coolant.
