Metaliic Piston-Packing.
NO. 142,640, Patented September9,l873.

UNITED STATES JAMES MASSEY, OF CHESTER, PENNSYLVANIA.
IMPROVEMENT IN METALLIC PISTON-PACKINGS.
Specification forming part of Letters Patent No. 142,640, dated September 9, 1873; application filed .lune 14, 1873.
I To all whom 'it may concern:
Be it known that I, JAMES MAssEY, of
Chester, in the county of Delaware and State of Pennsylvania, have invented a new and useful Improvement in Elastic Metallic Piston, of which the following is a specification:
- Figure l is a detail sectional view of my improved piston taken through the line x, Fig. 2. Fig. 2 is a detail sectional view of the same taken through the line y y, Fig. l. Fig. 3 is a side view of one of the rings, part being broken away to show the construction. Fig. 4 is a side view of the spring.
Similar letters of reference indicatecorrespondin g parts.
My invention has for its object to furnish an improved piston, which shall be so constructed as toadjust itself to take up the wear, and
described.
set-screws C, as shown in Figs. l and 2. D-is a cast-iron spring or coil placed upon the piston-head A, and by the elasticity of which the open rings E are held out against the cylinder. The open rings E have inwardly-projecting flanges formed upon their outer edges, which rest upon the edges of the spring D. The rings E taper, or are beveled upon their inner sides, from their outer to their inner edges, as shown in Figs. 2 and 3, to allow the spring D to be made heavier in its middle part. F is the follower or movable head of the piston, by which the spring D and open rings E are held down upon the stationary head of said piston. e is a stop-piece attached to one end of the open rings E to overlap the other end and 'keep it in place.
Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- A piston-packing formed of head A, centering-block B, set-screws G, coil D, open rings E, and follower F, constructed and arranged as JAMES MASSEY. Witnesses:
JOSEPH HoLT,
THOMAS S. HALL.
