To all whom it may concern.:

Be it known that I, BRYANT B. Envianos,

citizen'l of the United States, residing at Berkeley; in the county 'of Alameda and State of California, have invented new and useful 4Improvements in Tater-Heaters, of which the following is a specification.'

My invention relates to Water-heaters, and pertains more particularly to instantaneous, automatically controlled gas water-heaters. It is an object of this invention to provide a means wherebya Siiglelieater'of this class may beein loy`ed to supply heated water to several in ependent l points'of distribution, in combination with .means for properly reg istering' the amount of .water drawn and gas consumed by Atheindependent party service, or at point of distribution, so that the correci. charges'inay bemadeagainst eachindividual consumer.. v

The invention consistsof .the elements, the

construction and combination of elements, or

their equivalents, and willV be,v clearly s'et forth in the following specification, and acis a side elevation o companying drawin" in whicli'fthe figure glie device.-

^ 1 In this class of apparatus, a heater .of suiti able construction isemployed having an inlet for cold water, eirculatingrcoils anda` hotwater outlet; a. ,fs'uitalile burner issupplied with fuel romffasource of supply, the fuel bein usually automatically controlled, and

ivhic is' ignited by the customary pilot,- ilight.

4In the embodiment of my invention as actually reduced to practice, vI use a heater 2 of any desirable construction, in the lower art of which is mounted aga-s or other urner 3, sup lied with fuel through aV connection 4 with the manifold 5. A series of coils 6 are inter osed .above the burner 3,' and cold water is le in from the up r manifold ,would 7, and passes outheated near t e bottom of the heater into a head 8.

For the purpose of providing an apparatus 'that-is adapted to furnish heated water to a pluralit ofA independent systems, such as be require in av large apartmenthouse, or to several distinct consumers,it'is necessarv that the water delivered into the 7 shall be registered to each consumer using it, and that the amount he uses,

and no more, be properly recorded. To accomplish this,su1tab e mechanical orother means 4must be ern loyed whereby the open-v ingof any draw-o faucet in a given service secu re mat-ically operate to open a spring-actuated sup ly control valve,'such as at 9, to admit col water through its respective inlet ipe 10 into the common manifold 7. There ore, each hot water service ipe l1, leading from the head 8, is provide/ with a valve 12 of suitable character, but here shown as a pis'- ton-valve, the water passing from the pipe 11 tothe top of the piston 13, andwhen the faucet 14 is opened', the waterpressure drives the piston 13'down, and a chain or wire 15 connecting the piston 13, and a lever 16, serves to open supply valve -9 to which ,water passes after going through a meter 18. It is thus manifest that no water can `pass through meter 18, Aor valve, unless the pressure below the piston 13 is relieved by openin thus a owing the piston 13 to descen open the v'alve 9.

The valve 9 and piston 13 are cach provided with asmall by-pass 17. and 19, respectively, for theequalization ofpressure ,and in order to insure a ainst accidental operation-of valve 12, a c eck valve is interposed betweenV it and the :heater 2.,; Vliile I havedescribed the operation and construction of a single Sivice -systein connected tothe head 8, and manifold ff, a plurality of systems may be supplied, is shown by the inlet pipes 10, and out et pipes 11.

Each stein isy individually co'iinected to the mani old 5 by a gas su ply pipe 21, leading from meter 22 to a va ve 23, which may be opened on the downward stroke ofifpiston 13 and rod 24. When the piston descends andopcns valve 23, gas passes throughs. valve at 25, ivh-ichis closable by a thermostat 2G interposed in the length of delivery pipe 11, und effective to close valve 25 when' the water has reached a predetermined teinperature. It will now be seen that no gas can flow to the manifold 5,'and thence to the burner 3, and that no water will pass to the manifold 7 until some faucet, such as 14, is opened to permit the piston 13 to' descend and -open valveA 9 against its spring, and also to open the gas valve 23.

The usual pilot light supply 27 leads from the upper part of the gast-valve 28 and is and as many pilot lights as 'there are independent service systems.

This construction provides a perfectlyK au a faucet 14 in theservice pipe 11,

adjacent the burner; 3, there may be pipe 11, leading from the head 8, will autoi i'io tomatic heater adapted to serve several distinct'parties, and provides for the accurate and independent recording of material consumed by each. i

This specification and; the drawings'set .forth one simple arrangement for the aceomplishment of the functions of the invention,

principles involved.

.The port 17 in the amount of supply to disturb the equilibrium when said source is opened, and as this port is slightly larger than the port 19 in the `piston 13,

valve 9 allows a: small this result will follow: When the discharge V cock isclosed equilibrium within the appa- 20 ,Spring foonteinp 2 5 i ratus is restored through theopening 19 in :the piston, and the return of the piston and its connected parts is insured by means ofja 19a.A l

It .will be understood-1 that a single'pilot light might be used, but the present dewce ates such a light for eachzseparate service, so that although only using a v ery small quantityof gas, that vamount will be:

properly` divided among thecOnSumers.

It acts in 4thefmaiiner usual to this, class of machines to regulate the tern eratuijeuof thewater.`..-Tlie How of gas and otwater areproperlyi--proportioned at all times inthi's apparatus. 4'
