VALVE.

Specification .of Letters Patent.

Patented Dec. 4, 1917.

Application filed June 26, 1917. Serial No. 177,104.

To all whom it may concern:

Be it known that I, MARTIN B. SMITH, a citizen of the Unlted States, residing at (.lharlottesville, in the county of Albemarle' and State of Virginia, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to a valve which is especially adap Led for use in connection with the flush ia nks of closets, and the like.

The primary object of the invention is to provide a valve of this character which will comprise comparatively few parts and may be used in connection, with both the old and new style of flush tanks now in use and is so constructed as to insure the seating of the valve upon the completion of the discharge of the water from the tank and to positivelyprevent the water escaping from the tank into the flush pipe when the valve is seated.

Another object of the invention is to provide a vitreous valve having associated therewith a stem of novel construction which is passed through guides so arranged with relation to the stem as to positively prevent the valve from becoming broken under the influence of the inrush of water to the tank.

A further object of the invention is to provide a seat for a valve of thischaracter which may be mounted upon an outlet pipe forming a part of the valve so as to prevent the seat from becoming distorted and weakened through continuous use.

With these and other objects in view, the invention resides in the novel combination and arrangement of parts, which will be hereinafter described and particularly pointed out in the claims;

The preferred embodiment of the invention has. been illustrated in the accompanying drawings, although no restrictionis necessarily made tqthe precise details of corn struction therein shown, as changes, alterations, and modifications, within the scope of he claims may be resorted to when desired. 1 In the drawings:

l i gure 1 is a longitudinal section through a portion of a flush tank showing the improved valve applied thereto and in elevati on.

Fig. 2 is a view similar to Fig. 1, the valve being shown in section.

Fig 3 is a detailed view throughthe valve to more clearlyiillustrate the construction of,

the valve stem and manner of connecting the valve therewith.

Like characters of reference denote corresponding parts throughout the several views in the drawings.

Referring now to the drawings in detail, the letter A designates a portion of a flush tank of the type now in common use which i has connected therewith the improved valve B. The valve 13 includes an annular body 5 at the ends of which are formed flanges 6 and 7,.the flange 7 being adapted to contact with the bottom of the tank A adjacent the overflow opening therein in which is received a threaded extension 9 on the body for connection with. the flush pi e on the closet bowl (not shown in'the said extension being retained in the opening in the tank by a nut 10 between which'and the bottom of the tank may be interposed a packing ring 10 if found desirable.

The body 5 has formed thereon a horizon tally extending and hollow arm 11 with the outer end of which is connected a vertically extending overflow pipe 12 which serves as a J support for a collar 13 which is held in adjusted position thereon by a set screw 14, said collar having formed thereon an extension 15 in which is adiustably mounted a stem 16 having formed integral therewith at its outer end a channeled head 17 for a purpose which will hereinafter appear.

The extension 9 on the body. 5 has extending transversely thereof ,a cross bar- 18 in which is formed a vertically extending opening 19 in alinement with the channel "in-the head 17. A circular valve seat 20 preferably formed from rubber'an d corresponding in diameter to the diameter of the flange 6 is secured thereto by a ring 21 overlying said seat and. flange and having passed therethrough and through openings in the valve seat and flange securing elements 22, s uch as screws, or the like, which enable the valve seat to be quickly and easily replaced when the occasion requires or. permit the reversal rawings),

thereof if found desirable. "The valve seat 20 has formed therein a central circular opening 23, the wall ofv which lSbBVBlBd to incline downwardly and outwardly toward the inner surface of the body 5. g I I am well aware of the fact that valve seats having a circular opening provided with a beveled wall as shown are in common use but these valve, seats are all connected with the valve easin s with the beveled wall in clinin upward y and outwardly which permits t e valve seat when softened by the. water in the tank to allow the water within the tank to pass between the beveled wall. of the seat and the valve resting thereon and I find that I can obviate this objectionable feature of these valves by arranging the valve with the beveled wall inclining downwardly and outwardly and clamping the valve on the flange 6 with the ring as shown.

A'hollow oblate valve 24 to rest upon the seat 20 is preferably formed of some suitable .i"itreous material and is provided. at one of its ends with a reduced and central extension 25 and at lts other end with a central.

.ing 26 in one end thereof so that the tube may pass through the opening 19 in the cross bar 18 which serves as a guide therefor. The tube 28 is 'ex'teriorly threaded for a portion of its length as at 2-9 and has engaged witlrsaid threaded portion nuts 30 by means of which the extension at the other end. of the valve may be firmly engaged with a packing 31 within a cap 32 carried by the other end of the tube and adapted to encircle the extension on the valve. 'lhreadedly retained in the tube 28 is a rod 3?) forn'iing the olher part of the valve stem and passing through the channel in the head 17 which servesas a guide therefor, the rod being formed above-the head'with an arm 34 to be engaged by a suitableoperating lever shown).

I am Well aware that there are valves somewhat similar to mine now in use which aresuspended by a stem having connection with the overflow pipe but In. these valves the stem does not consist of a two-part mem- -il'i.-. at nce apparent lhal a vulnl'or llusli tanks has been pro\ iile l liiuli will coniinis few parts, thus redlieing the cost of manu faclure and with the parts H) comm-led and arranged as to insure the proper seating of the valve and to positively prevent the es cape of water from the tank when the valve is seated.

Having thus described the invention hat is claimed as new, is:

1. In a device of the class described, a valve seat and a valve to seat thereon including a hollow oblate body having an extonsion at one end thereof and an opening at its other end, a tube passing through said body and extending beyond the same-through the said opening in the end thereof, a cap at one end of said tube to einrirole said extension and close the open end thereof, means on the tube for holding said extension in engagenient with said cap and a rod adjustal l v z'nounted In said tube.

In a device of the class described, a valve and a seat therefor including an an nuln r body having a flange at one end thereof. a'valve seat re-movabl v m unted on said. l'lange and havirre a central circular opening therein, the wall of which inclines downwardly and ni1'uaI'tlly toward the'inner peripheral wall of the bm'lvl I In testimony whereof I aliix my signature.

MARTIN RUSSELL SMITH.
