WATER HEATER Filed Nov. 50, 1939 gin/UWM M /J H of Z U7 1 .m u v of? i h f In L 7 '07 WF'HadQZOC/W Patented Oct. 15, 1940 UNITI-:nf STA-TIES Pmisirrv oFFicE wnum r. Haddock, New'oriem. u. 1 Application November 30. 1939, Serial No. 306,962 s cam (ci. 122-11) This invention relates to a water heater and has relation more particularly to an apparatus -of this kind commonly known as a storage heater, and it is an object of the invention to provide a device of this kind wherein the water is heatedv by heat extending both around and through the water. It is also an object of the invention to providev a heater of this kind wherein the water is sub- .Iected to a materially large area of heat radiation thus assuring quick heating of the water.

Theinvention consists in the details of construction and in the combination and arrangeless expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. f l

The novel features of my invention will hereinafter be definitely claimed. I

In order that my invention may be the better understood, I will now proceed todescribe the same with reference to the accompanying drawing, wherein:

Figure 1 is a view in elevation of a water heater constructed in accordance with an embodiment of my invention:

Figure 2 is 'an enlarged vertical sectional view taken` through the heater as illustrated in Figure l with parts in elevation and a portion broken away.

As disclosed .in the accompanying drawing, I denotes a bese member of desired dimensions and which has4 its margin detlned'by an upstanding flange 2. `The central portion of the member is provided with a materially large opening 3 and depending'v from the member I are the legs '43 whereby e base member I is supported at a desired el vation above the iioor or kindred supporting surface.

Mounted upon the base member I and in close contact with the inner faceof the flange 2 is the lower end portion `of an elongated casing C preferablymade of sheet metal and which has disposed therearound a lamination 5 of asbestos or other heat insulating material.

Thiscasing C is of preferred dimensions and its upper end is open but normally closed by the cap 9 resting thereon from above. This cap 6 may be of cast iron or other suitable material and the central portion of this cap 6 is in communication through'the opening 'I with the flue 8 through which the products of combustion are discharged.` Resting upon thebase member Iv and positioned within the casing C is an elongated and vertically disposed water tank T. 'I'he lower portion of this tank T is snugly engaged around a dome-like member. 9 of cast iron or the like and which provides the combustion chamber I0. 5 In communication with this chamber Ill at the central portion of the member 9 is the lower end portion of a'coil A of copper or other material readily conductiveof heat. f

This coiiA extends to the upper end .of the 10 tank T and discharges through an opening II at the axial center o f a cap I2 closing the upper end of the tank T. This cap I2 is also preferably of cast iron while the peripheral wall Il of the tank T is preferably of sheet metal. The open- 15 ing II in the cap I2 is directly below the opening l in the cap 6 for the casing C.1 The tank T is o f a major diameter less than the interior .diameter of the casing C whereby is provided a heating chamber I5 surrounding 20 the tank T and the lower portion of this heating chamber I5 is in communication with the combustion chamber I0 through the openings I6 disposed through the upper portion of the dome-like member 9 and the adjacent portions of the 26 tank T.

Positioned within the chamber I5 and extending from a point closely adjacent the top of the member 9 to the top of the tank T is a spiral baille I1 to cause the products of combustion en- 30 tering the chamber I5 through the openings I6 to pass upwardly around the tank T in a circuitous path thus materially facilitating the heating of the water within the tank T.

The products of combustion as they pass up within the chamber I5 are discharged out through the ilue but at the same time-also heat the top wall of the cap I2 whereby the water within the tank Tis further heated.

It is also believed to be obvious that the heat or products of combustion lwill pass up through the coil A whereby the water within the tank T is still further heated.

Positioned within the chamber I0, in the present embodiment of my invention, is a heating unit 5 of a gas burner type. This unit I9 has leading thereto a pipe line I9 leading from a suitable source of iluid supply. Interposed in this line I9 is a conventional thermostatlc valve 20 under vcontrol of the thermal element 2i extending in- 50 wardly of the tank T. As' a result of the rise and fall of the temperature of the water within the to the heating unit.. v

Extending down within the tank T through the caps 8 and I2 is a supply pipe 22 leading from a suitable source of water supply and terminating within the bottom portion of the tank T. Also extending through the caps 6 and 'i 2 is a carry-oi! pipe 23 for the heated water and which pipe ter- Y adapted for use by reason of the convenience and.x

facility with whicl it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to'theprecise ar-` rangement and formation of the several partsY herein shown in carrying out my invention practice except as hereinafter claimed.

I claim:

1." A water heater comprising a base member, a casing mounted upon said base member. a tank within the casing and also mounted on the base member, `a dome-like member iitted within the lower portion of thetank to provide a heating chamber,.means for closing the top of the casing, means for closing the top of the tank, the tank being spaced from the casing to provide a surrounding chamber andthe top of the tank being spacedfrom the top of the casing, the dome-like member and adjacent portions of the tank having openings therethrough to aiiord communication between the heating chamber and the chamber surrounding the tank. a spiral tube interposed between the dome-like member and the top of the tank, said spiral tube being in communication with the chamber of the dome-like member and dischargingwithin the space between the top of the tank and the top of the casing, the top of the casing being provided with a flue opening,y means for delivering water within the lower portion of the tank, and a discharge for'the water within the' tank incommunication with the top portion of the tank.
