Abstract
9803. Pagan, J. T. April 30. Pistons.-Relates to methods of preventing axial motion of the packing of steam or air pistons, piston valves, pump pistons, air-pump buckets, &c. Fig. 1 shows a piston valve, the packing-ring e of which is formed with shoulders, which are held between a shoulder on the flange a of the piston and a shoulder on a ring or cylinder c, which is pressed on to the packing-ring by a spring d confined between the ring c and the junk ring b. The ring e may be solid, or adjustable in diameter, or may be self-expanding or expanded by springs f. The split in the ring e is covered by a segment g, the ring c and the flange a being recessed to receive it. In the piston shown in Fig. 6, the ring c and flange a are not recessed to receive the packing e. The ring c has a flange which extends over the edge of the junk ring b, and leakage is prevented by a packing-ring h. Tightness is secured by a number of spiral springs d, or by a single spiral spring, as shown in Fig. 1.
