INVENTORS BY MX/W ATTORNEYS Patented Nov. 28, 1939 v UNITED STATE VALVED FLUID OUTLET Earl B. Goon, Niles, and Garris W. Heath, Niles Township, Berrien County, Mich.

Application October 1, 1937, Serial No. 166,816

* 1 Claim. o1.'24s 1s This invention relates to a valved fluid outlet, and particularly to a valved coupling between a permanent gas line and a gas burning utensil.

Heretofore, it has commonly been the practice in piping a building for fuel gas to run the various branch lines from the metered supply line to the approximate locations of the gas burning utensils to be used, as gas heaters, stoves, fireplace fixtures and the like, without regard to appearance, without uniformity and with a mere open threaded end adapted for connection by means of a simple union with the utensil feed line. This is objectionable because it is unsightly, and additionally because it is necessary to shut off supply of gas to all branch lines at the main or supply line in order to disconnect, repair or replace any one utensil. Furthermore, if a utensil such as a heater is disconnected and removed, the bare projecting pipe end is exposed to view, and the projection relation thereof to the wall or floor through which it extends is so unsightly as to materially detract from the appearance of the room.

It is, therefore, the primary object of this invention to provide a novel automatic closing valve structure at the outlet of a fluid pipe line.

A further object is to provide an automatically closing valve structure of simple and inexpensive construction which can be manufactured and assembled with minimum labor and skill.

A further object is to provide a valve of this character which can be readily manipulated for adjustment and cleaning while closed and without requiring closure of the supply line.

A further object is to provide a novel and attractive supply line outlet.

Other objects willbe apparent from the description and appended claim.

Referring to the drawing, the numeral I designates the walls, and H of the floor of a room,

said walls having the usual base trim board l2 extending along the bottom thereof. In the wall In and board l2 we form a small opening l3. Within opening l3 of board 12 we mount a frame [4 whose ends l bear against board l2 at opposite sides of said opening and are secured to said board l2 by screws it. The intermediate portion l! of frame I4 is rearwardly off-set to project into opening l3. Over the opening l3 and frame it is applied a face plate l8 which is also secured to place by screws [6. An aperture I9 is formed centrally in ofi-set portion ll of frame l4, and larger aperture 20 is formed in face plate i8 concentric with aperture Hi.

We prefer to extend the fluid supply line 2i through floor l l between the usual studding which supports and spaces the plaster walls H! of adjoining rooms, and mount an elbow Z2 thereon opposite wall opening l3. To this elbow we connect valve housing 23 which preferably comprises an interiorly screw threaded tubular portion 24, for connection with the elbow, and a concentric reduced exteriorly screw threaded portion 25 projecting 'throughfframe aperture I9 and forming an exterior shoulder 26 adapted to bear against the inner face of frame portion ll at the margin of aperture IS. The housing 23 is also provided with an annular interior shoulder 21 at the juncture of

housing portions

24 and 25 which forms a valve seat. Within housing portion 24 is positioned a valve disc 28 adapted to seat marginally against shoulder 21. A valve stem 29 projects centrally and axially from disc 28 into housing portion 25 to extend substantially the full length of said housing portion, said stem preferably be ing formed integrally with said disc 28. Stem 29 is screw threaded at its outer end portion 30, and is provided with a transverse groove 3| in its end. A narrow elongated plate 32, preferably having arcuate ends concentric with housing portion 25 and fitting therein with a slight clearance, is screw threaded on the end valve stem 29 at its center. Between the interior housing shoulder 21 and the plate 32 is interposed a coil spring 33 to normally urge plate 32 outwardly and thereby seat valve disc 28 on shoulder 21. The parts are so arranged that the outer face of plate 32 is normally positioned slightly inwardly of the end of housing portion 25. A nut 34 is threaded on reduced housing portion 24 to urge the same outwardly relative to frame l4 so that said frame is gripped between the nut and shoulder 26 to rigidly hold said housing in place. The housing portion 25 terminates adjacent face plate I8, so that when a cap 35, preferably having a gasket ring 36 against which the end of portion may bear, is threaded thereon to seal thehousing, the same will project only. slightly, if at all, beyond said face plate. The face plate aperture 20- is preferably of a size just sufiicient to permit tightening and release of said cap or of a fitting.

For connection of the outlet with the feed conduit of a utensil, we provide a tubular fitting 31 of a size which will fit freely in housing portion 25. In spaced relation to one end of this fitting 31, we provide an exterior shoulder 38, as by an annular bead. A nut 39 adapted for threaded connection with valve housing portion 25 fits loosely around the end of fitting 31 and is provided with an inturned flange 40 adapted to bear against shoulder 38. Within the nut 39 is mounted a ring gasket 4| adapted to seat against shoulder 38. The shoulder 38 of fitting 31 and the nut 39 are so proportioned and arranged that the outer edge of nut 39 will project beyond the outer edge of the fitting when flange 40 abuts shoul der 38.

It will be seen from the above that, by having the valve arrangement permanently connected to the gas line, the same prevents leakage of gas when a utensil is disconnected and the supply line is uncapped. It is, therefore, unnecessary to close the main gas line when efiecting a connection or disconnection at any branch thereof. Also, the work incident to opening and closing of all pilot lights in one system. and relighting the same incident to reopening the system, is avoided when working at any branch thereof.

The outlet is attractive in appearance by virtue of the face plate 18, particularly when a cap 35 for sealing the outlet matches the face plate and serves substantially to fill face plate aperture 20.

The parts of the fitting 3i and plate 32 of the outlet are so proportioned and arranged that, in connecting the same, the nut 39 can be well started on threaded outlet portion :25. before the end fitting 3'! is urged by said nut into engagement with plate 32 to unseat valve 28. Inthis way the leakage of gas incident to valve opening in effecting the connection is reduced to a minimum which occurs only for the length of timev 28 in effecting the connection and disconnection aforesaid is readily adjustable while maintaining valve 28 closed by changing the position of plate 32 on valve stem 29, as is readily achieved by the screw threaded interconnection of said parts, and the valve stem groove 3| by means of which the valve stem may be manipulated or controlled during relativerotation of the same and plate 32.

It will also be seen that stem groove 3| affords means for rotating valve 28 on its seat for release of dirt particles'which may be lodged between the valve and its seat without interrupting the gas service or requiring disassembly of parts. The valvestructure and assembly also has the advantages of simplicity of construction, very few component parts,- inexpensiveness, and quick and simple assemblyin its housing.

We claim:

In a valved fluid outlet, a housing having an annular internal projection spaced from its end, a valve adapted to seat on said projection and having an integral outwardly extending stem threaded at its outer end, a narrow cross piece threaded on said stem and freely shiftable longitudinally within said housing and adjacent to the end of said housing, and a coil spring bearing against said projection and said cross piece at
