VALVE.

Application filed' September 27 1920." Serial no. 413,013.

To all whom it may concern:

Be it known that we, J OHN F. ROGERS and JAY S." MoGLIMoN, citizens of the United States, and residents, respectively, of Cleveland Heights, in the county of Cuyahoga and State of Ohio, and Cleveland, in the county of Cuyahoga and State of pOhio, have invented a certain new and useful Improvement in Valves, of which the following is a full, clear, and exact description.

This invention relates to valves, particularly to slide valves for conduits connected to gas producers, furnaces and the like adapted to convey high temperature gases and fumes, and the principal object of the invention is to provide a valve which is acid, water and fire-proof, and which will not disintegrate or warp under the action of the high temperatures to which a valve for this purpose must be subjected.

Heretofore considerable difficulty has been encountered in constructing a valve which could successfully withstand the high temperatures, and which would perform its intended functions in an efiicient manner when used over a long period of time. Valves formed of metal, both sheet and cast metal, have proved to be ineffective, due to warping characteristic which interferes with the opening and closing movements of the valve, but is particularly objectionable as it prevents the tight and secure seating of the valve when it is closed.

A valve made in accordance with the present invention answers the requirements very effectively, and overcomes the objections to the various types and forms of valves heretofore tried, and none of which were wholly successful. l

The invention may be briefly summarized as consisting in certain novel details of construction, and combinations and arrangements of parts which will be described in the specification and pointed out in the appended claims.

In the accompanying sheet of drawings, Fig. 1 is a face view of the valve and its casing; Fig. 2 is a transverse sectional view of the same showing the portions of the conduit to which opposite sides of the casing are attached; Fig. 3 is a detached view of the valve proper, showing its mode of construction; and Fig. 4 is a detail view showing a portion of the frame and the reinforcement for the cement filling of the valve.

their bending the Referring now to the drawings, 10, 10 represent two portions of a conduit which is adapted to be closed by our improved valve. Between these portions of the conduit and secured thereto is a rectangular valve casing 11, adapted to receive the valve 12, which in this'instance is a slide valve adapted to'be elevated to open the conduit and to be lowered to close it. In this case the top of the valve has connected to it a counterweighted cable 13'wl1ich shifts the valve, this cable passing over sheaves 1 lsupportedin aframe-work 15 attached to the upper part of the valve casing.

It will be noted beforetaking up the construction of the valve, that on one side of the frame there is a circular seat 16 against which one face of the valve 12 is pressed (when the valve is closed) by clamping wedges 17 which are adapted to be inserted through opposite edges of the casing 11 between the valve and wedge engaging lugs 18 on the opposite side of the frame to that having the seat 16. At the bottom of the casing there is a removable hood or cover 19 which permits the'removal of any sediment which collects at the bottom of the easing, and at the top of the casing there is a pair of plates 20 pivotally supported at 21 so that they can be rocked into and out of engagement with opposite sides of the valve. The function of the members 20 is to seal the top of the casing.

Taking up now the construction of the valve, it will be noted that it includes a rectangular metal frame 22 which is preferably formed of channels, as shown in Fig. 4, and extending across this frame at substantially the center thereof is a reinforcement consisting preferably of a wire mesh 23 which is preferably secured in position by bringing the marginal portions of the mesh or screen through openings in the channel and ends of the wires laterally and twisting them together if necessary. This frame with its central reinforcing medium is completely filled with a hard heat nd acid resisting monolithic material consisting preferably of what is known ashigh temperature cement.

After a great deal of experimentation we find that the best and most successful way of forming this valve is to lay the frame with its reinforcing mesh on a flat, horizontal table having a very smooth upper sur- 110 face, and then to completely fill the frame with the cement in plastic form, the top surface being smoothed off flush with the top surfaceof the frame. Then the valve and the table are moved into a furnace, and the valve is heated by being burned or vitrified at a temperature between 900 and 1500 Fahrenheit. This drives absolutely all moisture from the cement which becomes thoroughly fused into one solid mass which Will successfully withstand a temperature from 2600 to 3200 Fahrenheit without Warping was next to the table on which the valve is formed and burned, is very smooth, and it is this surface which is placed next to, the circular seat 16. Obviously, therefore, in

view of the smoothness of this surface, and the fact that the valve does not warp or dis- 1ntegrate, the valve when closed and'when wedged against the seat forms with the latter an absolutely tight joint. Having describedour invention, we claim:

1. A fire, Water and acid proof valve for conduits conveying high temperature fluids, comprising a frame containing a reinforcing material and filled With a hard, heat-resisting monolithic mass.

2. A fire, water and acid proof valve for conduits conveying high temperature fluids, comprising a metal frame having a reinforcing Wire mesh extending across'the same substantially centrally with respect thereto, and filled with a hard, heat-resisting fused monolithic mass. e g

In testimony whereof we hereunto ailix our signatures.
