Referring to Athe' drawing,A designates an annular water receiving chamber having yexteiififml ribsror lugs A and'internal ribs or lugsv A. This chamber A` irn'ClOSl i?? Patented June@ n'- nenn confining sneu B, this shell being .ipported from the .chamber A by braces A pipe line b? leads from the vtop off the chamber A to a draw-oif faucet(),"it

being. understood that this faucet provides i means for controlling the How of the heated water from the chamber A. A water supply-pipe line b2 leads from a. valve casing, h to which water is `conducted through a water supply pipe b from a 'city service line Tan-STATESTPATENT or other source ofwater supply. It will be i noted tha-both of these lines pass upwardly throughii-.t-he center of the annular water chamber and that consequently both of these pipes are subjected tothe action of the heat rom a n rnes-istdisppsed beneath the an nular chamber A and is pvided-...ygithports i or openingsd at which the gas is lighted in .the usual andy well known manner, it being understood that `the flame willbe directe against the underside of the annular cham? ber A and will pass upwardlythrough and laround the walls of said annular chamber, 'and will heat these walls andthe lugsAy as burner D. It will be noted that and A2, and .the water contained lin the chamber A. pilot -burner e is disposed Vadjacent the burner D and is connected by a branch pipe e with a main gas suppl pipe f. A stop cock tV located in the-'bran pipe e'- `controls the flow of gas to the pilot burner if ..e and. provides means for, cuttln'gy off the' gas from the pilot burner.A

"valve-casing g, the end of pipe project-f Thn supply pipe f lends directly to n" y ugintol said casingat gf 1n such manner."l

that a leather disk i carriedby and formingpart bf a gas valiegz may be forced against ythe end `of saidlpipie as will behereinafter set jforth., The Y valve 'gbyra yscrew*g,.s 'ee Fig. 4. A -r is connected1t0thegas valve g? and to a piston .m` disposed within `the-:valve casing h,

nally grooved at m2. A spring j is. disposed iis secured toy theoasy :this pistonbeing'peripherally and longitudibetween thefpiston m andthe end ofthe valve casing la and normally tends to force said piston and therod'c toward theleft in Figs.' 1- and 2, it being apparent that movef ment toward the left of these parts will through suitable f move the disk vaway fromjthe lend g.' of Vthe gas supply pipe, to permit gas to flow. Vthrough pipe line fand mixing chamber f'" to the 'main burner D.' The rod c passesV boxes h ,and g.

The valve casings g and hare `connected by tie rods 71-these tie rods passing through flanges p of the valve `Casin s, and having nuts ,g threaded thereon. ne of the tie rods carries a pair of pins n', and the rod c is provided With-an arm R, these parts serving purposes which Will be described in the operation of the device.

` .thereby yheat the water in 1the chamber A@ The operation' of the ,device is as follows: Assuming that the Water in the heater is cold and that it is desired to heat the' same the stop cock .t is opened :and the pilot .burner e lighted. 'The varm .R is then grasped and the rod c is forced to Vthe left againstthe pressure. of the water lupon thepiston m, and this arm is then swung downwardly to the dotted 'line position shown in .5 and is .engaged betnieen `the pins n', `:these .pins' then serving to hold thegas valve g2 in its open position. This will permit :an initial {lo-w 'of gasto .the main :burner D, which gas will be ignited from theqgnlot :burner-Ae .to

Al-ter the Water has been suiciently heated, the a-rm R lis .disengaged ztrom between .the

vpins /n/ and the pressure ofthe Water .u-.pon

the piston .fm 'fforoes the rod c and .the gas valve 'g2 toward the right until @the disk abats against :the l.end of Vthe pipe g 'to cut off the `flowv of gas to the burner D. The

parts will remain yin this position until the faucet O .isopened for the purpose -ot draw- -in hot Water therefrom. The opening of this faucet relieves :the pressure uponlthe piston m and the spring y' acts to force the piston :toward the let to' again open the gas valve land adm-it gas to It will therefore .be seen that :as ihot winter is'W-itfhdravvnv from thefchamber A,the water tiowing into the -chamber through the pipe, line b* will :be heated.v the faucet 0 .is again closed, the increased pressure 'oit the `Water :upon 'the Vpiston .m again *forces Vthe `and -Lthezrod c toward the right to close .the gas valve and `cut .oil -the 'further flow yoffgas to 'the-main burner D. The piston .m iis .fgrooved atm/2 *to 'permit the -esca of .amy Water thathas'leaiked 'past the piston' into the :night hand end off the valve -casing J2..y The port termed 'by :this groove is a comparatively .smal-l' one, so small .that the pressure upon the right lhandside of the'y piston'will .not be Vsuflicient to neutralize the ressure. f=upon the left v:hand side' thereof. 11 like-manner, the gas valve g2 may `be grrooived at sito permit the escape of anylgas that ihasleallred past this' valve andiinto they le-'Bt 4'hand-end of the gas va'lve casing g.

"From fthe foregoing description, it will be seen Vthat simple and eflicient means arelherein :provided for accomplishing the objects of the invention, but While the elements shown 'and :described are Well adapted to` serve lthe purposes tor which they are in- .tended,' it is to be understood that'the in-4 .the mai'n i burner ID..

valve is yielding y connected with vention is not limited to the precise construction set forth, but includes Within its purview such changes as maybe made Within the scope of the appended claims.

As represented in Figs. 6 and 7 the cham-l bered casing coupling section h having the pocket la? for the piston fm, has an annular seat h3 at the junction of such ocket with the chambered enlargement; an the piston Lhas atvits end portion which is located .in

such enlargement an external annular flange m* ofvcompressible material heldin place by .the screw confinedretainer m5 and to constitute when Athe .piston is forced to its 'limit .of the high pressure of the Water, a

valve to close against the seat h3 `and pre-l vent leakage of Water along the rod'or stem c which connects the piston and. as valve to 'possibly leak through the stu .ng box u.

And the chambered `casing-and coupling section g hasthe cylindrical pocket in which the -gas valve is slidab'ly fitted made with an annular seat gT for the end of .the gas valve opposite its end which closes against the'end off ,the gas supply pipe f which 'protrudes into the chambered `casing' and thus when the water pressure is lowered and the piston recedes so as -topermit the gas valve to' bel opened -to permit the flow of the gas through the pipe f tothe lbu-rner, the end of the gas valve opposite its rgas shutting off 'end will close aganstrthe :seat 97 and prevent a leakage :off .gas through the iding paint.. of the coupling section g Whic has a contracted' opening. for the rod. and which is provided with a stuifmg box u?. :order that after the `gas vwlvehas seated, as shown in Fig. 6 to "offset the shunt of gasfrom the burner,

and in order that the piston m may also certainly lclose :a ainst the seat n, the gas the rod c. As specifically constructed to this aend, the lcylindrical lgas valve is l.maille with an .inclosed longitudinal cylindrical .cha'mbe1.' closed atats one vend `by the screw plugi which :carries the valve proper z' andhavin-g a contracted o enfing the size ofthe .rod c -through lits .o er end; and Ythe rod :has .a' head -orxenlargement c playing in the anan- 1115 ner 4of .a ypiston 11n the-said cylindrical -chrambergin the valve :one vdirection .against spring :at which is' provided n Vcompression between the end of the piston-iks enlarge- -ment' o3 and the inner .end ofthe plug 5; l"1`here-t`ore,it will be understood that iai-the. action of the rod united `piston and gas valve a resumption of the Water pressure .to lits high normal 'will be effect-ive 'to' force the piston to the right ',(in the relations in which the parts are here illustrated) and force the zgas valve toits position for {shutting 'oi,.w1th,certainty, vthe flow of gas from the gas supply-,this closure occurring more or less beforethe piston hasmoved to its in the other with the reaction offthe l`spiral rightward limit; and then after the positive closing of the gas valve, the piston under the high Water pressure in being forced so that its valve member m* will close against the seat 7L? will have such iinal movement under the compression of the comparatively light spring c* inclosed Within the body ofthe gas valve.

Having described my invention, `vWhat I claim is:

l. In a device of the. character described, the combination with a water receiving chamber, of a cold Water service lpipe dis-4 being capable of both reciprocatory and rotative movement, and a locking member carried by4 said rod which serves, when said rod is rotated to one position, to hold the gas valve in its open position.

2. In a device of the character described, the combination with a water receiving chamber, of a cold Water service pipe discharging thereinto, a hot Waiter service pipe leading therefrom, a burner beneath said chamber, a casing disposed in and forminga part of the cold Water supply pipe line, a piston mounted in said casing, a gas Valve casing disposed in alinement with the piston containing casin a rod connected to said piston and exten Vin into the gas valve casing, a gas valve carrie by said rod lwhich serves to control the iiow of gas through the gas valvev casing, means for conducting Vgas from said casing to the burner, a spring bearing between 4the piston and the end of its casing which normally tends to open the.

gas valve, the piston and gas valve connected rod being mounted for both rotation and reciprocation, a transversely extending member carried by said rod, and a fixed member with which said transverse meniber' is adapted to engage when the rod is rotated, to thereby hold the gas valve open against the tension of said spring.
