The incon'iin 1' water passes through the water inlet '4-. o the heater down throu h the heater and qufi'throu'gh the heater disc arge 10 and closed by means of the thermostat. When the faucet or draw-61f cock 12 is closed, the pressure equalizes and the. valve "is automatica'lly closed. In order to permit the cir-- ,culation ofwater through the heater, when no water isbeing drawn ofi therefrom, I

' provide .a circulation or return pipe 14, I which connects the discharge of the heater I to the inlet, so that the water'circulates through the discharge pipe and thermostat tube 21 to the return or circulation pipe 14, thence to the inlet 4:, and through'the heater, thus circulating pastthe thermostat, which controls the gas valve and maintains the water in the heater at a predetermined or.

approximately at a predetermined tempera-.

ture.

,;In order to control the inlet and the return hor circulation pipe, I provide a circulation member 15 closesT be valve ,preferablyconsisting of the valve member 15,'which isxadapted, when closed, to seat upwardly against the seat 16, thereby closing the circulation or return pipe. The

valve member 15 is provided with a'down- .wardly-projec'ting stem 17, on which the inlet valvemember 18 is slidably mounted.=

-Between the valve members 15 and 18 I arrange a spring 19. -;The valve members 15 and 18 are so ,1 arrangedthat the valve ore the valve member 18 opens, and vice 'versa; the-spring 19 being compfessedwhenthe valve member 18 is opened y. the incoming water. By this arrangement I secure in a simple and effective manner an automatic valve which efiec- 'tively controls the circulation. I show one form of this circulation feature in my 00-,

- pending case hereinbefore referred to,--in which the circulation valve. is controlled dir'ectly by the water inlet valve, and I present claims broadly to the .circulation feature in that application. This form ofmy invention, however, has certain advantages in regard to the arrangement and. location of the parts, and is the embodiment ofmy invention' preferred by'me where a storage tank or extensive circulating system, such as Ihave indicated in conventional form in my said co-pending application before referred to, is

not desired. a

The valve 20, shown in detail in Fig. 4, is

adapted to control the discharge of the heater,that is, it may be adjusted to control the quantity of water drawn on during any given time it being intended that this shall be shut 01% according to the capacity of the heater.

I have illustrated and described my invention in detail in the form pref erred by me on account of structural slmplicity and economy. I am, however, aware that it is capable of-considerable variation in structural details without departing from my invention.

Having thusjdescribed my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The combination with a water heater, of a as burner therefor; a gas valve arrange to controlsaid burner; a water inlet for said heater; an automatic water inlet valve arrangedtoopen said gas valve; a

water discharge for said heater; a thermo-- stat connected to said gas valve; :1 return or, circulation connection for said water discharge and water inlets; an automatic circulation valve comprising a circulation valve member, said circulation valve member 'havinga downwardly-projecting stem, an inlet valve member slidably mounted on the stem of said circulation valve member, and a spring interposedbetween said valve members, said circulation valve member being adapted to close before said inlet valve member is opened and vice versa.

.-2. ,The combination with a water heater, of a gas burner therefor; a gas valve arranged to control said burner; a water inlet for said heater; an automatic water inlet' valve arranged-to open said gas valve; a water dischargeior said heater; a thermo- "stat connected to said valve; a return or circulation connection for said water discharge and-water inlets; an automatic circulation-valve comprising a circulation valve member, an inlet valve member, and a spring finterpo ed between's'aidvalve members, said circ'ulat on'valvemember being adapted to close before. said inlet valve member is opened and vice versa.

3. The combination with a water heater,

of a gas L burner therefor; a gas valve ar ranged to control said burner; a water inlet for sa d heater; an automatic water 1n- --let valve arranged to open said gas valve;

:1 water discharge for said heater; a thermostat connected to said gas valve; a return or' circulation connection for said water discharge and water inlets; an automatic circulation valve comprising a circulation valve member, said circulation valve member having a downwardly-projecting stem, and an inlet valve member slidably mounted on the stem ofsaid circulation valve member, said circulation valvememb'er being adapted to close before said inlet valve member is opened and vice versa.

4. The combmat on with awater heater,

close before said inlet, valve member is opened and vice versaL- The combination with a Water heater, of a gas burner therefor; a gas valve arranged to control said burner; a water in.- let for said heater; an automatic water inlet valve arranged to open said gas valve;

a Water" discharge for said heater; a return or circulation connection for said Water discharge and water inlets; an automatic circulation valve comprising a circulation valve member, an inlet valve member, and a spring interposed between said valve members, said circulation. valve member being adapted to close before said inlet valve member is opened and vice versa.

6. The combination with a Water heater, of a gas burner therefor; a gas valve an ranged to control said burner; a Water inlet for said heater; an automatic Water inlet valve arranged to open said gas valve; a Water discharge for said heater; a return or circnlat'i on connection for said Water discharge and Water inlets; an automatic circulation valve comprising acirculation valve member, said circulation valve member having a stem, and an inlet valve member slidably mounted on the stem of said circulation valve member, said circulation valve member being adapted to close before said inletvalve member is opened and vice versa. In witness whereof, I have hereunto set my hand and seal in the presence of tvvo witnesses.
