Application file [1 May 15,

To all whom it may concern. i

Be it known that 1, CHARLES l i anrnns, a citizen of the United States and a resident of the city of Chicago county of Cook, and State t Illinois have invented certain new and useful Improvements in a l/Vater Heater; and I do hereby declare that the following is a full, clear, and exact description of the same reference being had to the accompa nying drawings, and to the numerals of reference marked thereon which form a part of this specification.

In practically all water heaters of the burner and coiltype the cold water to be heated is admitted at the lower end of the water coil and passes upwardly through the coil to be heated by meansot air which is drawn into the lower portion of the heater to be heated by the burner, and is then caused to rise in the heater around the water coil and be drawn out through a flueor draft pipe connected to the upper portion or end of the water heater to cause a forced draft therethrough. A great amount of heat is thus wasted due to the fact that the heated air only acts in its upward passage through the heater to heat the water, and is then exhausted while still containing sutlicient heat units adapted for further heating This invention relates to an improved form of a water heater wherein the air which is heated by a burner is permitted to pass upwardly through a water coil and then pass downwardly around the water coil to be exhausted from the lower portion of the heater without forced draft to thoroughly heat the water and at ford an arrangement whereby the heated air acts in both its upward and downward passage l'lll'fllltl'l. the heater to utilize substantially all the heat units in the heated air lhtllfl'e it is permitted to be exhausted from the lower portion ol the heater.

llt is an object of this invention to con-- struct a water heater wherein the circulati ng air after heating the water is perm" o l to escape through the lower p tion o? the heater without forced drafh Another object of the invention is the construction ofa water heater wherein an opening is provided in the lower portion of the heater to check the draft to permit substantially all of the heat units in the heated air circulating in the heater to be 1918.

utilized before the air is exhausted through the lower portion of the heater.

It is also an object of the invention to construct a water heater wherein the loops of the water coil are disposed. closely together to permit heated air to pass 'upwardly through the coil and then downwardly therearound to utilize practically all ortthe heat units in the heated airfor heating the water circulating in the coil before the air is permitted to escape from an air 6 outlet pipe positioned at the lower portion of the heater. i

It is animporta-nt object of the invention to construct a water heater wherein the heated air is caused to circulate upwardly through and downwardly around a water coil to heat the water therein before the air is permitted to leave the lower portion of the heaterthrough an exhaust pipe wherein the draft has been checked.

Other and further important objects of this invention will be apparent from the disclosures in the specification and drawings. c c i The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a front elevation of a water heater embodying the principles of this invention and showing parts broken away to show the interior construction.

Figure 2 is a section taken on line 2-2 of Figure l. with parts in elevation.

Figure 3 is an enlarged section taken on line 3-3 of Figure 2. t Figure 4 is an enlarged section taken on line 4-4, of Figure 2, with parts omitted. its shown on the drawings:

"The reference numeral 1, indicates a base or support provided with a plurality of air intake openings 2, in the sides thereof, and having integrally termed therein a flange ring 3 to receive seated thereon the apex tured bottom oi base plate 4;. of an outer casing or housing; 5; which is closed at its upper end. Provided in the lower front portion. of the casing 5, is a door 6, adapted f to permit lighting of a large gas burner 7. which is securely mounted centrally in the base plate 4, and is connected with a gas supply pipe 8 equipped with a'suitalole valve 9, on the exterior of the heater;

end of which rests upon the partitionplate 11, Surrounding the central opening therein, and having a portion thereof removed from the lower front side thereof to afford an opening 13. The upperend of thesleeve 12, which isopen, is closed by means of a cover or capqli l, which engages around the upper end of the sleeve and 'is'suspended in position from the top of the outer casing by means of screw bolt'lfi.

Projectin into-a suitable openingprovided iirthe rear of the outer casing directly above the partition plate 10, is one end of an-air =outlet or exhaust pipe 16. Provided in the partition plate-'10, directly in frontof the inner open: end of. the exhaust pipe 16 isan :opening' 17', actingto-check anydra-ft throughthe exhaust pipe 16 A water coil 183' is disposed vertically withinathesleeve 12;,'and has the-loops there of closely-seated one on-the-'other-toprevent air from: passing therebet weeni The lower loops of the-watencoilaproject into the hood 11," and-terminate in a straight pipe 19; which connects-up with a cold water, supply pipe 20. The: uppermost loops of the coil are separated and loop around within one-- anotherand terminate in a straight pipe "21, which projects upwardly through the cap 14, and the top of the outer casing 5, to connect up withany hot water pipe system. 1 The operation-is as follows 2' I By-bpening the gas valve9, gas is sup plied to the-- burner 7, which is lighted through the door 6, thereby causing the air surroundingthe burner to be heated: The heated air rises-,- and due to the: arrangement of the water coil the heated-air passes upwardly through the coil-to heat theuvater circulating: upwardly therethroughv The upper end of the sleeve 12, is closed by the cap 1. 1, which acts to deflect theheatcd air downwardly around the-s upper separated loops of the coil and further causes the heated. air-to pass downwardly around the lation of heated air as indicated-by the an rows Thehe'ated iair reaching the lower end of theslee've 12, onthevexterior of the coil-18, passes through-the opening 131: into the space afforded between the? sleeve 12 and the inner walls ofthe casing -ii a-nd' then passes outwardly ,or' is exhausted through ope ning 17, is xprevide d the1plate1'10;toeheoleranyi drafti g-m s d suction in the exhaust pipe 16. An arrangement is thus afforded whereby the heated air within the heater utilizes substantially all of its heat units to heat the water circulating in the coil 18, both as said heated air passes upwardly through the coil'and'as it passes downwardly around the exterior of the coil. The water heater is thus highly efiicient and results in a minimum waste of heat, since the air passing outwardly through the exhaust pipe 16, has practically exerted a heating effect upon the water in" the coil during the entire upward and downward passage'of the air through the sleeve 12.

The tight or close arrangement of the loops of the'coil 18, prevents theheatcd air from passing therebetwecn untilithe upper end of the coil is reached, and since there is no forced draft or suction in the heater the heated air does not readily pass; from vthe heater. The coil 18-, being heated from both sides causes the water flowingin'thecoil pipes to be rapidlyheated, thereby produc ing a water heaterof simple-and effective design wherein the heated air circulates through the heater and-isnexhaustedz with out suction or forced draft through; the lower: portion of the heateri V I am' aware that numerous detailsof con struction may be "varied-through :a wide range without departing; from the princis ples of this invention, and-I therefore'do not purpose limiting the patent-grantedotherwise than necessitated by the prior art;

I claim as my invention: I 1
