Application filed June 6, 1918.

. others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to water heaters wherever heaters and for whatever same may be used or adapted to. It consists in the peculiar structure formation combina- .tion and arrangements hereinafter -described.

In the drawings:

Figure l is an elevational view of the outer shell of the water heater as assembled.

Fig. Q is a vertical section on the line 2-2 of Fig. l.

Fig. 3 is a cross section on the line 3-3 of Fig. 2.

Similar letters refer to similar parts.

A is an outer shell extending below an inner shell B. The shellB is spaced from the shell A thus providing a water space or jacket surrounding the whole heater. D is a burner tube which may be of any convenient type and which is controlled in the usual manner. E is a water inlet pipe controlled by a three-way cock which turned in one direction leads from the water passage Gr to the inlet E and turned in another direction leads to an outlet H and also closes off the water inlet Gr. By this means the heater may be blown off at any time. The inlet pipe G leads to an internal water system made up in the following manner: A series of water chambers J consisting of metal lens shaped receptacles united at their edges by stand pipesto a series of hollow flattened rings' K preferably formed by welding metal pieces together of such form that when united they form flattened tubes. Each of the chambers J J are inclined at an angle from the horizontal, as shown, sutficiently to secure drainage and each of the hollow tubes K K, except the top on-e, are also inclined at an angle for the same purpose. When assembled the angle of the receptacle J J and the tubes K K are opposed and the higher edge of the chamber J is united. with the lower Vportion of the tube K,

as shown partly in section in Fig. 2. At one point L the lower tube K communicates with the water jacket and the higher tube K also communicates with the water jacket upon the opposite side at the point M. An outlet N is provided for the expulsion of the heated contents. The tubes K are large enough in diameter so that they come substantially in contact with the inner shell B at their cuter edges, as shown at P P, whereas the receptacles J are about two-thirds of the diameter of the inner shell B and when arranged, as shown in the drawings Fig. 2, it will be seen that the products of combustion can pass under and around the receptacle J J and through the interior of the hollow rings K K ultimately in a zigzag course as shown by the arrows.

It is obvious that this device might be heated with any source of heat but I have shown for that purpose a gas jet D. A small door D in the shell affords meansfor ignition and for observation and may have a sheet of mica in the door if desired.

I close off the bottom by the curved diaphragm R and allow the in-coniing air for draft purposes to pass in through small holes S S, as many as may be desired and having dampers F F if desired for adjustment in the shell of the device below the water jacket. This curved diaphragm in the bottom and adjacent to the burner as it is heated by radiant heat from the flames above it vaporizes any moisture of condensation which may drip down in the bottom of the heater due to the products of combustion impinging upon the cold surfaces at the initial stages of heating and also keeping the bottom of the heater dry from any moisture that may cond-ense after the burner is turned off. The products of combustion pass through a chimney T.

The operation of my invention is clearly understood from the foregoing description By this means I am enabled to produce a very efficient simple and cheap heater, there being no parts of cast iron and all the parts are welded or brazed.

Having thus described my invention, what I desire to claim is:

1. In a water heater, a heating element comprising a series of annular and lenticular water chambers arranged in superposed alternate relation and connected in water circulation and having a water inlet to the .lowermost of said chambers and a water out- CII let from the uppermost of said chambers with the lenticular chambers inclining in a direction from the horizontal and the annu lar chambers inclining in an opposite direction, and a combustion chamber inclosing said heating element having an opening in the top for escape of the products of combustion and an opening in the bottom for the passage of a gas burner, the side Walls of said chamber being arranged as a Water jacket connected in circulation With the heating element at a point Within the inlet and outlet of said element and to constitute a part of said element, and said chamber being arranged With a series of circumferentially disposed openings to provide an air supply for the burner.`

2. In a Water heater, the combination with a combustion chamber having an opening in the bottom for the passage oi' a gas burner and an opening in the top for the escape of the products of combustion, of a heating element arranged in said chamber comprising a series of annular and lenticular shaped Water chambers arranged in superposed relation, said lenticular chambers being of smaller diameter than the interior of the combustion chamber andL the annular chambers of substantially the same diameter as the interior of the combustion chamber; means to connect said chambers in Water circulation; a Water inlet to the lowermost oi' said chambers arranged to be connected to a source of supply; and a Water outlet from the uppermost of said chambers;

3. In a Water heater, the combination of a combustion chamber; a heating element in said acket comprising a seriesoif lenticular shaped Water chambers of less diameter than the interior of the Water jacket and a series of annular Water chambers superposed to and alternating with the lenticular shaped chambers and of substantially theA same diameter as the interior of the Water jacket, said annular and lenticular chambers eX- tending at acute angles to each other; means to connect said chambers in Water circulaw tion with each other and the jacket; a Water inlet to the loWermost lenticular chamber;

and a Water outlet from the uppermost annular chamber.

In testimony whereof, sign `this speciication. I

EDWARD T. CURRAN.
