ANTISCALDING-VALVE.

Specification of Letters Patent.

Patented J an. 2,1912.

To all whom it may concern:

e it known that I, ROBERT H. BRYON, a citizen of the United States, and a resident of Bay Ridge, in the county of Kings and State of New York, have invented certain new and useful Improvements in Antiscalding-Valves, of which the following is a description.

The present invention relates to valves and has particular application to a device of the type referred to, commonly known as an anti-scalding valve.

In carrying out my invention, I have in contemplation the provision of a valve provided with hot and cold water connections and so constructed that when it is operated to permit the water to flow, the cold water will issue at the point of discharge before the hot water passes through the valve, thereby obviating the possibility of scalding.

To the accomplishment of the above recited object and others of a similar nature my invention consists in the construct-ion, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

While I have herein shown and described one embodiment of my invention I wish it to be understood that I do not confine myself to all the precise details of construction as there may be modification and variation in certain respects without departing from the spirit of my invention or exceeding the scope of the claims.

In the accompanying drawings wherein I have delineated one embodiment of my valve, Figure 1 is a vertical longitudinal sectional view of a valve embodying my improvement; Fig. 2 isa vertical sectional view of the same taken transversely through the valve; Fig. 3 is a longitudinal view partly in elevation and partly in section showing the valve open to permit the full flow of thehot water; Fig. 4 is a cross sectional view taken on the line 44 of Fig. 3; Fig. 5 is a similar view taken on the line 55 of Fig. 3; Fig. 6 is a detail view, partially in sec tion, of the valve stopper and connected parts; Fig. 7 is a sectional view taken on the line 77 of Fig. 6.

Referring now to the accompanying drawings in detail, the letter A indicates the valve body as a whole, having a cold water inlet 5 and a hot water inlet 6. This hot water inlet has achannel 7 provided with and terminating in a vertical tubular extension 8, extending approximately centrally upward into the chambered portion of said valve, the upper edge of said tubular extension being inwardly inclined as is shown at 9, to form a bearing surface for the disk 10, which is preferably formed of rubber or similar material and is connected to and forms a part of the valve stopper, which latter I have indicated as a whole by the numeral 1'1.

At 12 I have shown an annular wall flange extending inward from the body of the valve, said flange having its upper edge portion beveled as at 13, and upon such beveled portion is designed to be seated the gasket or ring 14 preferably of the same material as the disk 10, said ring being secured to the main portion of the stopper by means of the binding collar or ring 15, threaded onto the body of the stopper, said ring having its lower end extending slightly inward as at 16, to form a small retaining flange for the seat ring or gasket.

The valve stem, which is indicated at 17, passes downward through the vertical extension 18 of the valve body, which extension has its interior wall threaded as at 19, to receive corresponding threads 20 formed on the enlarged caplike portion 21 of the valve stem. The valve stem is also formed with a short flanged stud-like portion 22 designed to be connected with the valve stopper 11 by means of the flanged cou pling 23 threaded onto the extension 2-1 of the stopper 11.

Depending from the stopper body is the thimble 25 which is in the nature of a comparatively long tube and is adapted to telescope with and surround the vertical extension 8 of the hot water inlet. This thim ble is formed with a plurality of graduated apertures or 'openings 26 through which the hot water is adapted to issue on its way to the outlet 27 said openings being arranged in any preferred and convenient order. At its lower free edge the thimble is outwardly flared and beveled as at 28 so that when the valve is moved to permit the full flow of hot water through the outlet opening, the flared edge 28 will bear against the under surface of the annular flange 12 and diminish the supply of cold water from the outlet.

The upwardly extending tubular portion 18 of the valve is formed with a cap 29 having a stufling box 30 arranged therein through which stuffing box the stem passes, said stufling box being surmounted by a second cap 31.

The handle for turning the valve is indicated at 32.

From the above description taken in connection with the accompanying drawings the construction and operation of my improved anti-scalding valve will be readily apparent. In the position shown in Fig. 1 the flow of both hot and cold water is entirely cut off, the valve disk 10 and the ring 16 resting upon their respective flanges. Now if the handle 32 be turned to the left the valve stopper will be elevated and cold water will be permitted to flow through the inlet 5, the passage 5 between the extension 8 and the flange 12 into the body of the valve and then out through the outlet opening 27 to a shower or the like. If the turning of the handle to the left be continued, the thimble will gradually rise until one or more of the openings 26 comes above the top edge 9 of the hot water inlet extension 8, when the hot water will begin to flow through such openings into the valve chamber and through the outlet. If the turning of the handle 32 be then continued until the flared end 28 strikes the annular wall or flange 12, the flow of cold water will be partly cut off and the full flow of hot water be permitted through the openings 26.

It will be apparent that I have provided an eflicient anti-scalding device adapted particularly for use in houses and establishment-s where it is necessary to have a large supply of hot water always at hand, minimizing the possibility of persons using the device scalding themselves, as the device is constructed to have the cold water flow first, while the full force of the hot water is not attained until the valve stopper is elevated to the limit of its upward movement.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A valve having an inlet terminating in an extension centrally of the interior of the valve, a second inlet, and means for controlling the inlets comprising a stopper member having a tubular member outside of and telescoping with the central extension, said tubular member being provided with an outwardly extending projection adjacent the lower end thereof.

2. A valve provided with an inlet passage, a second inlet passage adjacent thereto, a stopper having a centrally disposed disk adapted to rest upon and entirely close'the first-mentioned passageway, such stopper also having a thimble extending from the stopper around said central disk and formed with perforations of different sizes, and a rimlike member carried by said stopper and adapted to rest upon and entirely close the second passageway.

3. A valve having a plurality of inlet passages, an outlet passage communicating with said inlets, and a stopper having a perforated member adapted to control the flow through one of said inlets, said perforated member having a projection thereon adapted to prevent the flow of fluid through another of said inlets when fluid is passing from the first inlet through the perforated member.

4. A valve having a plurality of inlets, an outlet, and means for preventing the flow of fluid from the inlets to the outlet, said means including a stopper having a depending perforated member adapted to close one of the inlets when a second inlet is open to the outlet and provided with a flaring end portion adapted to close said second inlet when the first mentioned inlet is open to the outlet.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
