THEODORE THURBER, OF AUBURN, NEW YORK.
Letters Patent No. 66,537, dated July 9, 1867.
IMPROVEMENT IN STEAM-PISTON PACKING.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, THEODORE THURBER, of the city of Auburn, in the county of Cayuga, State of New York, have invented certain new and useful improvements in a Compensating Packing Ring for Pistons for Steam Engines; and the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings making a part of this specification, in which- Figure 1 represents the face view of the ring, with its angular opening.
Figure 2 shows an edge view of the same.
Figure 3 shows a broken-oif section of the same in perspective.
My invention is an additional improvement to my former invention, for which I obtained Letters Patent, dated March 26, 1867, and numbered 63,185, and'consists in the recesses in bothedges of the packing ring, for the purpose of lessening or checking the force of steam and lessening the liability to leakage.
To enable others to make and use my improvement, I will describe it more fully.
Instead of the solid surface ring described in my above-referred to patent, I introduce the ring 0, which has a recess, N N, on its outer surface, into which a portion of the steam enters through the angular opening is, thereby reducing the pressure on the packing against the inner surface of the cylinder in proportion to the width and depth of the turned groove or recess in the ring, in addition to the reduced pressure, as set forth in' my former patent above referred to. The faintgrooves 2' z' in the edges of the packing ring C are designed to.
prevent the leakage or-escape of the internal force of pressure. The grooves it being stopped at the opening is, no steam or force can enter it from either end.
Having thus described my improvements in steam-piston packing, what I claim as new, and desire to secure by Letters Patent, is- I The grooves or recesses in the edges of the packing ring G, as and for the purposes herein specified.
THEODORE THURBER;
Witnesses:
Emu. F. Brown, J. B. Woonnurr.
