METALLIC PACKING FOR PISTON-RGDS AND THE LIKE.
T 0 all whom it may concern:
Be it known that I, GEORGE D. Romans, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Metallic Packing for Piston-Rods and the Like, of which the following is a specification.
lily invention relates to a new and useful improvement in metallic packing for piston rods and the like, and has for its object to so construct and arrange the packing rings of such a device as to render them more efficientand overcome many of the disadvantages which now exist and especially to pro vide for receiving the initial pressure and strain upon a non-compressible ring so as to relieve the compressible companion ring from undue strain, and where the packing is used upon explosive engines to shield the compressible ring from the direct heat from the cylinder.
\Yith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which Figure l is a section of a stutling box showing a casing therein and my improved arrangement of rings in said casing. Fig. 2, a face view of the l'ion-con'ipressible ring. Fig. 3, a section of the compressible ring, and Fig. 4, a face view of the latter.
In carrying out my invention as here embodied, A represents the casing which is usually made in two sections and adapted to be placed within the stufling box B and held therein by the gland C, and in the grooves of this casing I place a pair of rings consisting of a non-compressible ring D and a compressible ring E, and in practice the noncompressible ring is located nearest the cylinder and is intended to receive the initial pressure acting as a shield or baflie ring to the compressible ring E.
As here shown the compressible ring is usually divided in three sections on tangential lines, the sections being held together and forced against the rod F by a suitable spring G, but of course this compressible Specification of Letters Patent.
Application filed April 30, 1909.
Patented Dec. 20, 1910.
Serial No. 493,070.
ring may be divided in any other well known or suitable manner either in two or more sections.
The non-compressible ring D is here shown as made in two parts secured together by the screws (Z, but it may be made in a single piece, the only object in making it in two parts is to facilitate placing it around the rod without the necessity of removing the cross-head of the engine. When the pair of rings are in place in the groove the noncompressible ring I) prevents steam or other pressure from passing into the groove and gaining access to the outer edge of the compressible ring, which would tend to force this compressible ring against the rod, which is not desirable, as the spring G is sufficient to keep the sections of the compressible ring in proper contact with the rod.
The non-compressible ring covering the movable joints or abutting edges of the sections of the compressible ring prevents the passage of steam or other fluid through these movable joints and relieves the compressible ring of distorting strains, and when the packing is used on explosive engines this non compressible ring protects the compressible ring from the intense heat which would otherwise come in contact therewith and interfere with its functions. Of course I do not wish to be limited to the relative positions of the rings in the groove since under some circumstances it might be advantageous to place the compressible ring on the pressure side.
Having thus fully described my invention, what I claim as new and useful, is
1. In combination with a casing, a compressible ring and a non-compressible ring placed face to face and located in a groove formed in said casing, for the purpose specified.
2. In combination with the casing of a metallic packing, a pair of rings fitted in a groove formed in said casing, one of said rings being compressible and the other noncompressible, as specified.
3. In combination with a grooved casing, a compressible ring and a non-compressible ring arranged in pairs and fitted in the grooves of said casing, the non-compressible ring being located on the pressure side, as and for the purpose set forth.
4. In combination with a grooved casing, a compressible ring composed of three sections divided on tangential lines and adaptml to follow the pislon rod to compensule for l W021i, and :1 non-compressible ring made in two sections and bolted together so as not to follow the rocl or compensate for Wear, said rings being arii'ang'ecl in pairs and fitted in the grooves of said easing the compressible ring being located on the pressure side, as and for the purpose set forth.
ln lesliinony whereof, I have liereunlo zil'hxed my signature 111 the presence 01 two 10 subscribing Witnesses.
