JERME T. SMITH, OF SCOTLAND, SOUTH DAKOTA.

'WATER-HEATER.

notatie.

To all whom it may concern Be 1t lrnown that l, insonni` T. SMITH, a

' citizen of the United States, residing at Scotland, in the county or Bonhomme and State of South Dakota, have invented a new and useful Water-Heater, of which the follown ing is a specification.

This invention relates to water heaters, its object being to provide a lire bon the wall of which is hollow so as to contain water, there being a boiler supported above the lire bei: so as to overhang the grate of the stove, said boiler being connected to the interior of the fire bon by pipes which also serve to support the boiler. y

Another object is to provide means whereby the hot products of combustion are caused to circulate along the inner and outer' faces of the fire box and through and outside of the boiler so as thus to raise the temperature of the water to the highest possible degree.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

Tn the accompanying drawings the preferred form of the invention has been shown.

ln said drawings z-lligure 1 is a vertical transverse section through a water heater having the present improvements combined therewith. Fig. 2 is a vertical longitudinal section through the water heater, the smoke pipe being shown in elevation eXcept at its lower end. Fig. 3 is a section on line lr-B Fig. 1. F ig. a is a section on line C-D Fig. 2.

Referring to the figures by characters of reference 1 designates the base of a stove, the same constituting the ash box and having a grate 2 thereabove surrounded by an apertured ledge 3. A. smoke pipe l extends upwardly from the base at a point back of the ledge and is provided, at a point above the base, with a branch pipe 5 which opens into the upper portion of the stove casing 6, said casing extending around the ledge 3. A damper 'fr' may be arranged in the branch pipe 5 for the purpose of controlling the passage of products of combustion from the Specification o' Letters Patent.

Serial No. 715,931.

upper portion of the casing (5 and into the smoke pipe 4t. Mounted on the ledge 3 and between the grate 2 and the openings in the ledge is a fire bof; 7 having a hollow wall for containing water, there bein g feed pipes 3 opening into this hollow lire boi; so as to direct water thereinto from any suitable source. This fire boit is removably mounted on the ledge 3 and may be formed with an arch 9 in the front portion thereof and directly back of a clinler door 10. Grate teeth 11 may extend downwardly from the top of the arch, as shown, so as to retain fuel within the fire box and prevent it from escaping through the cliuker opening when the doorI 10 is open.

Extending upwardly from the fire box 7 are water conducting pipes 12 which serveto support a boiler 13. This boiler is preferably cylindrical and is arranged. directly over the grate 2. lllues 11i extend through the boiler from the bottom to the top thereof and the top of the boiler is spaced from the top of casing G so that products of combustion, after passing through the tlues 14 will be free to flow between the boiler and the top of casing 6 and thence downwardly within the casing to the openings in the ledge 3. An outlet pipe 15 extends from the top of the boiler and is adapted to convey the hot water to the point of use.

For the purpose of preventing the escape of the products of combustion between pipes l2, a sheet metal band or shield 1G is extended around the lower end of thc boiler 13 and rests on the top of the lire box 7. This band 16 may be provided with an opening 17 surrounded by flanges 13 extending up to the fuel door 19.

Tn order to prevent air from passing directly from the door of the ash boX to the lower end of the smoke pipe 1i, a partition 20 is arranged within the ash bon between the front door thereof and the opening 3. Thus the air entering the ash box from the door necessarily passes upwardly through the grate, through the tlues 14T, and, if the damper 7 is closed, necessarily downwardly to the openings 3 and thence out through the pipe Ll.

From the foregoing description it will be apparent that the fire bei; 7', pipes 12, and boiler 13 are constantly full of wat-er. lWhen fuel is consumed on the grate 2, the hot products of combustion Vwill pass upwardly along the inner surface of the fire box 7', along the pipes 12, and through the flues 14, thus raising the temperature of the water. After leaving the lues 14, the combustion products flow downwardly within the casing 6 and pass through the openings in the ledge 3 and thence into the ash box after which they flow into the smoke pipe 4. Thus the products of combustion serve not only to heat the interior surface of the fire box 7 and the walls of the iiues 14, but also serve to heat the outer surfaces of the boiler and the fire box. Consequently a considerable saving of heat is eifected and the temperature of the water is more quickly raised than would otherwise be the case.

It will be noted that the entire water heating portion of the stove can be easily placed in or removed from position within the casing 6, it being unnecessary to utilize any means for fastening the iire box or the boiler to the stove easing.

What is claimed is In a water heater the combination with a grate, of a lire box extending therearound and thereabove and having a hollow wall constituting a water container provided with an inlet and an outlet, an endless band extending above and supported solely by the fire box, a boiler closing the upper end of the space surrounded by the band, and pipes connecting the interior of the tire box to the interior of the boiler to support the boiler, said pipes overhanging the grate and extending into the path of the combustion products within the band.

In testimony that I claiin the foregoing as my own, I have hereto aliixed my signature in the presence of two witnesses.
