JOHN H. ASHTON, OF PROVIDENCE, RHODE ISLAND.

SELF-CLOSING VALVE.

Specification of Letters Patent.

Patented July 29, 1913.

Application filed September 12, 1911. Serial No. 18,869.

To all whom it may concern:

Be it known that I. JOHN H. ASHTON, a citizen of the United States, residing at- Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Self- Closing Valves, of which the following is a specification.

My present invention relates to adjustable self-closing valves proper, and it consists in the novel construction and arrangement of parts, all as hereinafter set forth and claimed.

In valves embodying my improvement, the parts, when assembled, are readily re-- movably mounted in suitable bodies and em ployed, as the case may be, in connection with sanitary drinking fountains, globe or stop valves, bibb or faucet cocks, gage cocks, compression valves, &c.

The valve part proper is adapted to be manually opened against the head or pressure of the fluid or water leading to and from it, and is automatically closed by the force or pressure of the fluid itself, the opening force being then removed. By means of my invention the device is adapted for use in a greater variety of valves; it is quick-opening, and it is capable of being more readily and accurately adjustable with respect to the degree of opening or inflow as compared with other self-closing valves. The valve-stem is screwless and is adapted, in cooperation with an interlocking stationary cam-shaped member to easily and positively uncover the valve-seat by a direct push upon the valve-stem or by turning the latter a short distance axially in either direction.

In the accompanying sheet of drawings, Figure 1 represents a side elevation of a valve device embodying my improvement, detached from its chambered body or casing, corresponding with the closed position; Fig. 2 is a central longitudinal sectional view of the same, but showing the valve open a preadjusted amount; Fig. 3 is a side elevation of the relatively stationary inner member having its wall provided with a cam-shaped opening; Fig. 4 is an end view of it; Fig.

411- represents the latter slightly modified; Figs. 5, 6, 7, S, and 9 represent, in reduced scale, side views of the device in the closed position and mounted in various types of chambered bodies or casings, the latter being sectionally shown.

The improved device A as a whole, capable of being removably screwed into a suitable casing or body, is represented most clearly in Figs. 1 and 2. It consists essen tially of the movable valve-stem member carrying a wheel 10 at one end and a valve 7) at the other; a stationary, laterally apertured plug member a having the valve-stem extending longitudinally through it and terminating in a seat a for the valve o, and also adapted to be screwed into a suitable body or casing member, the latter having a seat 8 against which, when the device is mounted in the body, the plug is adapted to bear. It further comprises an annular memm and its packing p of leather or other suit able material, recessed at p to receive said extension when the valve is closed. The barrel part a intermediate said end portions is or may be reduced in diameter and provided with one or more lateral openings (4 in its wall for the outflow of water, or other fluid, when the valve is open, all as clearly shown in Fig. 2.

The valve-stem has a hand-wheel w, or other analogous member, secured to its outer or upper end. Upon manually pushing or turning it, or a combination of both movements, as the case may be, the valve is readily unseated or opened, as will be later explained. The opposite end portion (Z of the valve-stem is reduced in diameter to receive the valve '2) and the valve-holding nuts 6. The valve itself may also be bored to receive the collar part (Z of the valve-stem; the inner edge of the collar extends into the said small annular recess 72 and also into the bore of the extension (0 when the valve is seated. Intermediate said collar (l and part (Z, both being of substantially the same diameter, the stem is reduced in size, as at (Z to permit ample area between it and the inner surface of the said apertured wall a for the passage of water. At or near the inner end portion cl the valve-stem is provided with a pin 2' fixed transversely therein, the same extending through opposite sides of the stem and capable of engagement with the sides 0 of the cam or wedge-shaped opening formed in the inner end part of the barrel portion 6 of the said stationary annular member 6. This last-named member I) is fitted at If and b to the interior of plug a, and also bored at Z2 to receive the movable valve-stem; the part b is also bored or recessed at b to receive suitable packing material f to prevent leakage around the valvestem. The packing may have a helical spring 8 bearing against it and the end of a stop-nut or adjusting member a fitted to the screw-threaded barrel portion If, as clearly shown. In practice the member a and check-nut n are adjusted so as to limit the valve-opening any desired amount, as indicated at t Fig. 1. Fig. 2 represents the valve thus opened.

It is obvious now that a direct push of sufficient force or pressure upon the operating element 10, secured to the valve-stem, opens the valve '0 to permit the inflow of fluid, assuming, of course, that the device A is first mounted in a chambered casing or body member connected to suitably arranged inlet and outlet pipes, and normally seated against seat 8 It is evident also that upon turning the handle to a short distance in either direction (see arrows a; Fig. 2) the frictional engagement of pin i with the corresponding sides of the cam openingc serves to impart additional leverage to the valve in opening the latter against the pressure of the intake water or fluid.

Fig. 4e1- represents a slightly modified form of the cam. In this case the valve and its stem can be turned only in one direction to open the valve. 7

The following is a description of various uses or applications of my improved selfclosing valve device A :In Fig. 5 it is represented as screwed into the body of a sanitary drinking fountain B, provided with inlet and waste pipes h, 72), and outlet or dischargenozzle 00 the annular collar a of plug a being fitted to an annular seat a of the said body. In Fig. 6 the device is shown screwed into a casing of the globe valve type, C, provided with inlet and outlet nozzles 72. 71 and internal annular seat .9. Fig.

represents the device removably mounted in a bibb-cock or faucet D having inlet and outlet ducts 71;, 72 and internal annular seat 8 It may also have a bottom nozzle and plug 10 Fig. 8 shows its application to a gage-cock E, the latter having an inlet nozzle 71-, an outlet or discharge nozzle 72. and seat .9 for the annular plugs collar a and Fig 9 represents a slight change in the device A in order to adapt it to be employed as a compression valve H. In this arrangement the main body or casing is provided. with inlet and outlet nozzles 72,8, 72?, a valve seat 8 a valve proper v and spring 11 the latter in this case serving to automatically close the valve. In this adaptation of the device the cam-opening 0 is reversed. The

valve-opening is attained by moving the stem (Z outward, or in the arrow direction, its limit of movement being arrested by the engagement of pin 2' with bottom is of camopening.

I claim as my invention and desire to secure by U. S. Letters Patent 1. In a valve of the self-closing type, provided with a chambered body or casing having an intake and a discharge nozzle and an interior partition dividing the chamber, said partition having an opening therethrough forming a valve-seat, the combination there- 'ith of a laterally apertured barrel member having a central opening throughout its length adjustably mounted in said body, the inner or lower end of the barrel member being annular and fitted to said seat, a manually actuated longitudinally movable rod or stem passing freely through said opening, a valve proper fixed to the inner end of the rod and normally closing the said seated annular end of the barrel, an annular member adjustably mounted in the opposite end portion of the said barrel member having said movable rod extending centrally therethrough, and means arranged to cooperate with the rod and the said annular member to assist in opening the valve, the latter automatically closing by means of the fluid pressure thereagainst when the opening pressure is released. a V

2. In a self-closing valve, the combination with a chambered body having inlet and outlet openings and an inn-er partition provided with a valve seat, of an apertured main annular member removably secured in said body having its lower end fitted to said seat, a normally stationary second annular member adjustably movable in an endwise direction in the main annular member having a V shaped opening formed in its wall, a valve-stem movably mounted in and extending through both the said annular members, a valve secured to its lower end and arranged to close against the corresponding end of the main annular member lugs eX- tending laterally from the valve-stem in normal engagement with said V-shaped opening, constructed and arranged whereby the act of pressing downward upon the stem imparts angular movementto it for unseating the valve.

In testimony whereof I have afliXed my signature inpresenee of two Witnesses.
