UNITED STATES IRA. E. STUMP, F CLEVELAND, OHIO.

SELF-CLOSING EAUCET.

Application led October 11, 1922.

n To all whom t may concern.'

Be it known that I, IRA E. STUMP, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and Vuseful Improvements in Self-Closing Faucets, of which the following is a specification.

My invention relates to improvements in self-closing valves such as self-closing faucets, basin cocks, and the like.

The present embodiment relates more particularly to a self-closing faucet for use in connection with basins or lavatory bowls, but it Ashould be understood that the improvements may be readily incorporatedin or adapted to various forms of bibs, cocks or faucets.

The primary object of my invention is to provide a generally improved self-closing valve or cock of the class indicated which will be exceedingly simple in construction, cheap 0f manufacture and eflicientin use.

A further and very important object is the provision of a self-closing valve of this class having its various working parts so ar ranged and disposed as to permit of the ready removal of the main valve and valve actuating stem or spindle without the necessity of turning olfthe water in the pipe or supply line below the valve or faucet, an improved secondary valve and valve chamber being provided which will automatically cut off the flow of water through the valve or faucet when such parts are removed.

A still further and very important object is the provision of an improved self-closing faucet of this class having a removable housing forming the secondary valve chamber and the main and secondary valve seats whereby such seats may be readily reground and whereby such secondary valve and valve seat forming member or housing` may be' readilyV removed or adjusted through the opening in the valve body or casing when the bonnet and cap and operating spider are removed.

A still further object is the provision of an improved cock or faucet in which the liability of breakage or disarrangemcnt of the parts is reduced to a minimum and in which the valves are fully opened or closed through a quarter turn of the crown wheel or handle and in Vwhich upon the release of such crown wheel or handle the valve parts will immediatelyV return to closed position.

A. still further object is the provision Serial No. 593,707,

of a valve in which the parts are so arranged and disposed as to follow a true centralized position in the opening and closing movement and in which the parts will be maintained in a true seated position to prevent leakage.

lith the above mentioned and other ends in view, the invention consists in the novel construction, arrangement and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure l is a side elevation, partly in central longitudinal section, of a self-closing faucet constructed in accordance with this invention, the parts being in a closed position.

v ily regrinding or of adjusting the valve seats Y vided withan annular seat portion 3, `and Similar numerals of reference designate like parts throughout all the figures of the drawings. e

The valve body or faucet casing l, may be of any suitable and convenientconstruction and when used as a bib cock or -faucet is provided with a suitable bib or spout la. The body or casing 1 is provided, in the present instance, with a suitable hase flange 1b, and a suitable extension lc, provided with `threads for attachment to the supply pipe.

lThe valve or faucet body is provided with a main inlet passage or port ld, terminating in an annular secondary valve seat le. The passage or port ld terminates in a secondary valve chamber lf, which may either be formed in the body itself, as shown at 1g in Fig. 14 of the drawings, or such secondary valve chamber may be formed within the base portion of a valve seat forming member or secondary valve housing 2, as shown in Figs'. l, 2,10 and 11 of the drawings.

As a means of conveniently inserting or removing the seeon'dalfv valve hereinafter referred to, and particularly as a means of readfor the main and secondary valves or of inspecting or replacing the parts, the valve seat forming member 2 is threaded to connect with a similarly threaded portion in the base of the casing l, as shown. The main valve seat forming member 2a, arranged above the valve housing 2, is provided with a secondary passage or port 2b, connecting the annular secondary valve seats 2z and 2d. The valve seat 2c is preferably bevelled or counter-sunk, as sliown, and the valve seat 2d is preferably raised or of ring shape for affording a firm seat for the main valve hereinafter referred to.

The secondary valve chamber 1f is provided with a secondary valve 3, adapted to operate between the valve seats le and 2c, said secondary valve 3 being preferably of square or angular form, as shown most clearly in Fig. 12 of the drawings, so as to provide passages foi' the inlet of the water when such valve is raised in view of the round or cylindrical walls of the valve housing 2.

VAs shown in Fig. 2 of the drawings when the main and secondary valves are in their open'positionsthe secondary valve Vis held down by the stem portion of themain valve and such secondary valve will not closey the secondary passage 2b, the closing of suoli secondary passage taking place automatically through the pressure of the liquid or wat-'er when the main valve and, operating mechanism are removed. l

The secondary valvel 3 is preferably prois provided with an upwardly extending prejectibn 3b, to enter the secondary passage 2?', as shown in'the drawings. A As ameans of providing a separate but operable connection with the lsecondary valve 3 and providing for the ready removal of the main valve. and valve operating stem and bonnet when desired, the bonnet 4, is provided with a central stem receiving opening 4a, adapted to receive and contain a reciprocatory valve stem 5, the latter being provided at its lower end with a valve head 5a, said head terminating in a central stem portion Qadapted to extend through the secondary passage 2b and to engage with and cooperate with therprojection 3* of the secj ondary valve 3. The stein 5b and head are adapted to removably receive and carry a removable valve comprising a disc 5C, and a washer 5d, of suitable resilient material such as feltor liber or rubber composition. Y

As a means of causing the main valve, designated generally by the numeral 5, to return to and to be maintained in seated position upon the valve seat 2d when opening pressure or movement on the operatinghandle and spider is released, the main valve is adapted to' operate against the resistance of a spring 6, surrounding the valve stem 5 andabutting against the .central port-ion of the bonnet 4. V

As a means of permitting longitudinal and preventingy circumferential movement of the valve stein 5' when the latter is actuated by the rotary actuating member or spider, hereinafter referred to, the valve stem is provided with oppositely arranged projections 5e, in the present instance, being formed by means of a cross pin, said projections 5?, being guided in oppositely arranged guide slots 4b in the bonnet.

The bonnet 4 is provided with a central bearing portion 4c, forming a cylindrical guide bearing portion adapted to removably receive and carry a valve actuating rotary member or spider 7.

The spider 7, is provided with oppositely disposed cam or wedge shapedymembers 7 a, connected by means of arms 7b, said members 7?L being provided with oppositely ar,-v

ranged inclines 7, adapted to cooperate with and travel beneaththe projections 56, so that when the valve actuating member 7 is moved to the right or left through themedium of the crown wheel 8, such inclined portions 7C will elevate the stem 5. Upon such elevation of the stemt) and the main valve 5 against the resistanceof the spring G, and as carried by the liquid or water pressure in the main passage ld, it will be obvious that the main and seeondary'valves will be moved from their seats to provide an outlet passage for the water as indicated by the arrows in Fig. 2 of the drawings. -Upon the rele-ase of the `crown wheel or handle it will'be seen that the inclination of the inclines 7c relative lio to the projections 5e is such that the spring Y action of the spring will automatically re-j close off any further flow of water. The rotary valve actuating member or spider 7 is removably retained in place upon the bonnet by means of a cap 9, having a cential opening 9, to receive the stem or spindle portion- 7d 0f the rotary actuating member which is provided with the crown handle or wheel.
