9904. Patterson, J. May 7. Pistons. - In packing for pistons and piston valves in which the expansion of a split spring-ring C is restricted by a restraining-ring A, the split in the spring-ring is covered by a portion B on. the restraining-ring of greater radius than the remainder of this ring. A discontinous flange D on the spring ring supports the ring C, and relative motion of the two rings is prevented by a pin E. One or two reatraining-rings may be used with each spring ring, as shown in the upper and lower parts of Fig. 7. The pin E with a single ring C enters the piston &c.
