5351. Pain, A. C., and Williams, B. E. March 5. Pistons.-To prevent undue expansion of the split packing-rings d, they are formed with flanges engaging flanges on a solid carrier ring c. The surfaces of these flanges are made so small that they wear at a rate sufficient to compensate for the wear between the cylinder and the rings. Wave rings f are placed between the rings d and the ring c, or between the rings d and the junk ring and coverplate. Steam may be admitted to the back of the split rings by grooves d<2> or by holes in the junk ring and piston flange. The ring c is carried on springs as shown, and may have packing and lubricating grooves c<2>.
