uprrED STATES PATENT OFFICE.
JOHN H. C HRISTIV IAN OF CLEVELAND, OHIO.
' lvlulvn.
To' all who m tt concern Be it knov In that I, JOHN GHRIsrMa'N,
a citizenof the United States, residing at- Cleveland, in the'county of Cuyahoga, and State of Ohio, have invented a certain new and useful Improvement in Valves, of which the followin is a full, clear, and exact description, re erence being had to the accom- This invention relates to improvements in valves of the type used extensively .as discharge valves for pumps; and it has for its" objects'to provide a compact valve of this character that is highly efficient; that is very durable; wherein the parts are readily accessible for the purpose of inspection and re-.
pair, and wherein those parts especially susceptible to wear are convenient of replacement. v
Furtherobj'e'cts will appear as I proceed to .describe my improvements by reference 1 to the accompanying drawing wherein Fig. 1 is a'sectional view through a valve constructed in accordance with my invention;
Fig. 2, a bottom plan view thereof; and Fig. 3 a view similar toFig. 1'of a modification. Describing the two forms of the invention herein illustrated in the order named, the
ing 2 that is-adapted to be screwed into the seat 1 of the valve is incorporated/in a spider comprising a threaded ring or bushvLalve deck of a pump or the like, and aboss 3 is supported centrally of the ring or bushing by a series of ribs 4.
- he ribs 4, it will be noted, are well below. theplane of the bottom of ring 2 so as not to obstruct the flow of liquid through thevalve open. Theribs 4 are shown as extending 1 upwardly along the innerwall'of therin'g' 2 where they terminate adjacent the-valve seat in stops 5, These stops serve to prevent undue movement of a metal valve. cap or'.
disks toward the-valve seat, the cap having acentral boss '1 that is guided upon .a spindle or stud 8 shown asghavingits inner end threaded into theboss 'A valve element 10 is carried by the cap for cooperation with the seat 1, and the same is composed ofa suitable yielding or compressible inaterial such .as rubber, that. is
sufiicie'n-tly resilient to permit it tov be stretchedlover the enlarged portion 11 of the cap andcontractwithin' the shallow groove Specificat ion of Lettersiatentl t t 7, 1 2 Application filed December-11, 1919. Serial a. 344,067.
Y that is formed thereabove'by the upwardly converging peripheral wall of the cap and a horizontal flange 13 which extends outwardly from the upper edge of .said wall. .The valve seat 1- and element 10 are shown as having correspondingly tapered cooperating surfaces; and the edge'portion of the 1 valve element preferably extends beyond the edge of the flange 13 so that the li uid pressure may act upon it to assist in orcing it against'the seat-. From the foregoing, it will be seen that the. valve element must necessarily be reasonably resilient, and to prevent undue compremion and consequential speedy deterioration of the element I pr0v1de the previously described stops 5 for limiting the inward movement of the gradually enlarges inwardly.- The packing ring is'designed for cooperation with the to of the boss 3, and the inner edge portion is adapted to be forced against-the surface of the boss ,by the pressure of liquid communicated to it through ports 16 in the cap.
A coil spring 20, which is'interposed between the cap and a plate 21 that is threaded 4 on thestud 8 .and held in place by a lock nut- 22 serves-to seat the valve.
fln Fig. 3 I haveshown a modification wherein the seat and valve element 10f are flat, and tlie' ribs 4? radiate from the boss 35in the plane ofring-2ff, t-he outer ends of "the ribs incor'poratingstopsfi for the 'cap 6% "This design, being somewhat more compact than the former may be. advantageously employedwhere the space is limited.
Having thus described my invention, what I claim is .1. A valve comprising 'a seat and acap by one of said parts and adapted to be stretched over an enlargement thereof and beyond which enlargement it is adapted to contraet'jfor. holding the member in place,
movable toward and from "the seat,,an anv nular member ofreslhent material carried against the seat. I
3. A valve compris ng a seat, a cap mov-.
inovable toward and from the seat, an air-- 'nular member of resilient material carried by the cap for cooperation with'the seat, thecap having an enlargement .over which the member is adapted to be stretched and be.- yond which it contracts fol-holding the member in place, and a stop for preventing undue movement of the cap toward the seat after said member -has been compressed able'axially toward andfrom the seat," the cap having a tapering peripheralwall with its larger end disposed toward the seat and a flange extending outwardly from the wall in opposed relation to theiseat, an annular member of resilientmaterial surrounding; said wall and engaging said flange and ar-. ranged for cooperation with the seat, and a stop for preventing undue movement of the cap toward theseat after said member has been'compres'sed against the seat.
i valve comprising a member having a centralseat and a peripheral seat, a guide rising from'the central seat, a cap movable along the guide toward'and from -the seatand having an aperture through which the guide extends, an annular member of resilient material for cooperation with the .pe-
ripheral seat, the cap-having an enlargement over which the member is adapted to be engaged "and beyond which it is arranged to contract for holding said member in posi tion, the'cap having also a cavity that is opposed to the central seat and which enlarges rial surrounding-the guide and adapted to expand within the cavity said ring being arranged for cooperation with the central seat, and a stop for limiting 'the. movement of the cap -toward. the's eat beyond a given distance thereby to prevent undue compression of the member and packing ring. v
5. In a valve of the character set'forth, I
the combination of a spider comprising. an
annular part incorporating a valve seat at opposite en I rising from theboss, a cap movable along compressible material carried by the cap for cooperation withthe seat.
Intestimony whereof, I hereunto: ailix my signature. y f
