PACKING-RING.
Specification of Letters Patent.
Patented May 14, 1912.
Application filed February 4, 1911. Serial 1:10. 606,620.
To all whom it may concern Be it known that I, CHARLES H. REY- NOLDS, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Packing-Rings; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to packings for valves, particularly to valves of the turning plug type, and has for its purpose to provide a valve packing which may be readily applied to and removed from position in the valve casing, and wherein a perfectly balanced pressure is obtained.
To these ends the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.
Referring to the accompanying drawings forming a part of this specification, in which like numerals designate like parts in all the views :Figure 1 is an elevational view partly in section of a valve equipped with my invention; Fig. 2 is a plan view partly in section of the parts shown in Fig. 1; Fig. 3 is an enlarged elevational side view of the ring-shaped packing constituting my invention and showing the hooks or overhanging portions of the ring; Fig. is a top plan view of the ring shown in Fig. 3; Fig. 5 is a cross sectional view taken on the line 55 of Fig. 3; and, Fig. 6 is an elevational view looking in the direction of the arrow of the ring shown in Fig. 3.
1 represents any suitable valve casing provided with the plug 2 having the passage 3 adapted to register with the port 1 of the casing,the said port, for example, extending in a direction at right angles to the axis of the plug 2. Surrounding the port 1 is an oblong channel 5 of any desired cross section, but preferably of the shape shown, and into this channel fits the oblong ringshaped, curved packing 6, as illustrated. The said packing is preferably tapered as shown in Fig. 6, and is made slightly larger in cross section than is the channel 5, so that when forced into said channel, it makes a tight fit. It will be understood that the said channel 5 extends up and down the cylindrical inner surface of the valve seat on each side of the port 44; substantially parallel to the surface of the plug 2, as indicated by the dotted lines 15 in Fig. 1, and that it also extends above and below said port, as seen in Fig. 1 indicated by the surfaces 16 and 17 respectively, so that it constitutes an oblong ring-shaped channel completely surrounding said port and of the same general shape as the packing shown in Fig. In order that the said ring may not turn with the plug, and may be more firmly held in said channel while at the same time it may be readily removed therefrom for the purpose of repairs, I provide the said ring with the overhanging curved or arcuate olf standing members 7 and 8, which fit snugly into those portions 16 and 17 of the channel which extend above and below said port 1, as above stated. The end surface 7 of the off-set portion 7 lies in the same straight plane; and the end surface 8 of the off-set portion 8 is curved or rounded, as shown in Fig. 3.
It will thus be seen that my improved packing ring 6 is really composed of the side members 18 and 19 joined by the curved or arcuate end members 7 and 8, and that the entire ring constitutes a segment of a cylinder with an oblong central space removed. In other words, the curved cylindrical surface 20 of the ring is concentric with the valve seat, and can be made to fit snugly against the convex surface of the plug 2, while at the same time it may be so firmly held in thechannel 5 that no danger of displacement is incurred.
In order to facilitate the ready removal before replacement of the ring, while at the same time firmly holdin the packing in place, I refer-ably provide the channel 5 with the flat surfaces or shoulders, as shown, and the ring with the corres )ondin flat surfaces 21, 22 and 23 fitting said shoiilders, as illustrated. It, therefore, follows when a valve is equipped with my improved packing, and it is desired to renew the packing, it is not necessary to send the valve back to the manufacturer in order to have the same replaced as has been customary heretofore in this particular type of packing, but the user of the valve may readily remove the plug 2, take out the old packing ring 6, and force a new ring in place, whereupon the packing will be as eflicient as before.
Vhile I prefer the form of ring disclosed,
and having the cross section illustrated, yet at the same time it will be understood that those skilled in the art may vary these fea tures without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claims.
What I claim is 1. The combination with a valve casing having a segmental recess in the wall of the chamber thereof, of a segmental vulcanized asbestos packing therefor, appliable and removable therefrom in its entirety, substantially as described.
2. The combination with a valve casing having a segmental recess provided with wedge elements; of a segmental packing ring therefor provided with wedge elements complementary to the segmental recess, and appliable and removable therefrom in its entirety, substantially as described. I
3. A packing ring for valves comprising a rectangular body with a rectangular open ing and having off-set and arcuate end portions, and having the side portions constructed with beveled edges whereby said ring may be wedged in its seat, substantially as described.
4. A packing ring for valves comprising a rectangular body with a rectangular open ing and having off-set and arcuate end portions; one of said arcuate portions having the end surface thereof lying in the same straight plane, and the other of said arcuate portions having a curved end surface; the sides of said rectangular body constructed with beveled edges whereby said ring may be wedged in its seat, substantially as described. r
In testimony whereof, I affix my signature, in presence of two witnesses.
