WATER-HEATER.

Specication of Letters Patent.

ra-tenten apre, rare.

Application led February 24, 19,11. -Serial No. 610,524.

To all whom it may concern.'

Be it known thatI, HAROLD C. MACAIRE, a subject of the King of England, residing at Chicago, county of Cook, and State 'of Illinois, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification.

My invention relates'to improvements in water-heaters particularly adapted for domestic use, the object ofthe invention'being the provision of an improved water-heater, which shall be simple ofl construction and eliicient in operation.

The invention consists of the novel constructions and arrangement of parts all as will be hereinafter more fully described and pended claims.

The invention will be more vreadily understoodby reference to the accompanying drawings, forming a partv of this specication andin which,

Figure l is the central vertical section of a water-,heater embodying my invention. Fig. 2 is a partial side elevationv of the water-heater, and 3 and d are detail top planviews.

The preferred form of construction of my invention as illustrated on the accompanying drawings comprises a vertical boiler 1 oi a common construction except as otherwise hereinafter indicated. A stand, or pedestal 2 supports a circular angleliron 3 which forms a seat or the boiler 1; and the gas-pipe d leadinginto `the boiler at the lower end thereof is connectedto an annular pipe or chamber 5 arranged under the boiler by means of a threaded lug t and pipe-connection 7. The .annular chamber 5 is arranged concentric withlthe boiler and is deburners 8 having controlling cocks 9, said burners being equally spaced on the chamber and accessible for regulating the size of the gas dames 10. A hinged door 11 ,is-provided on one side ofthe boiler opposite the lburn ers, this door being ordinarily kept closed would detract from the general appearance of. the water-heater. rEhe boiler 1 is provided with a closed top 12 and a trusteconical shaped bottom 13, the latter'having" a cylindrical ue 14 extending upwardly therefrom which is arranged in axial alinecent vthe bottomv 13, as illustrated in Fig. 1.

ment with the boiler 1 and passed through the `top 12 to. atmosphere.

The water inlet-pipe 15-is arranged Iparallel with the flue v14 and is passed through the top 12 and thence downwardly to adja- E@ When Vthe -water-heater'is in operation the boiler should be filled with water, but for n .clearness of illustration the same is indicated as only partially filled. In Fig. 1 a y drain-pipe 16 extends downwardly from the 35 bottom 13 of the boiler and is provided' with a stop-cock 17. 1A T'pipe-connection 18 isy inserted in the pipe 16'- just below the connection thereof with the bottom 13,' and one leg of said pipe-connection is screwed into a boss 19, provided on the'exterior member 20 of a hollow double-walled water-heating dorn'e, the interior member 21 of Said dome being threaded and screwed into the exterior member, as illustrated in Fig. 1. The mem- .bers 20 and 21v are frusto-conical in .form

and the sides of the former have less angularity than those of the latter, whereby the annular conical water space is heated uniformly wit-h the warmer water in the space between the top ofjthe members 2O and 21, it being understood that the flames 10 are so 4distributed as to uniformly heat the under surface of the walls of the member 21.

Arising from a central threaded lug 22 on thetop of the member- 20 is -a vertical water-pipe 23 which connects with a horizontal pipe 24 passed through the wall yof the flue 14., said horizontal pipe 24 terminating in a T-connection 25 which is in com-` munication with a service pipe 26 and a return iow pipe 27, water circulating through the later when the faucetsof the service pipe areA closed.

lin order to collect the water ofcondensa- @5 tion from the pipe 23 and member 20 a peripheral trough 28 is formed in the'surn face ofthe member" 20. 'The drip which would otherwise interfere with the action of the Bumsen burners is thus prevented'.

l it will be observed that the` member 21 forms a trap for retaining. the heatnnits generated bv the burners, which heat will be fully utilized for'heating water before it escapes.

A water-heater of the construction set forth is symmetrical in design, simplev of construction, and highly 'eiiicient in operaf tion.

While l have illustrated 'and described the u@ preferred construction for carrying my' invention into eect, this is capable of variation and modification without departing from the spirit of the invention, l therefore do not wish to limit myself to the precise details of construction set forth but desire to avail myself of such variations and modifications as come within the scope of the appended claims. v

Having describedmy invention what l claim as new and desire to secure by Letters Patentis:

1. A water-'heater comprising a-boiler; a hollow dome located under said boiler, said dome consisting of two superposed inverted frusto-conical members, the lower of which is smaller and inserted and threaded' into the upper; connections between said dome and said boiler, and means for heating said dome and said boiler, substantially as described.

2. A water heater comprising a boiler; a hollow dome located under said boiler, said dome consisting of two inverted rustoconical members, the lower of said members having a greater angularity than the upper so as to form a water space which gradually increases in width toward the top, said lower member being threaded therein; connections between said dome and said boiler; and a nceaes? burner projecting-its :dame into said con cavity, substantially as described.

. 3. A water-heater comprising a boiler; a hollow dome located under said boiler; means for heating said dome and boiler; a

-drain pipe for said dome, the interior of said dome being given a general inclination toward said drain pipe; and connections between said dome and said boiler, substantially as described.

4, A water heater comprising a boiler; a hollow' dome located under said boiler; a burner projecting its flame into said dome;

a drain pipe connected with the lower portions of said boiler and dome, the interior -of saidA dome being given a general inclination toward said drain pipe; a stop cock 1n `said drain pipe below said connections; and

a pipe connecting the upper portion of said -dome with the upper portion of said boiler,

substantially as described.

In testimony whereof I have signed my 'name to this specification inthe presence of two subscribing witnesses.
