JACOB HOUSER, OF MEDFORD, OKLAHOMA.

AUXILIARY WATER-HEATER.

To all whom it may concern:

Be it known that I, JACOB HOUSER, a citizen of the United States, residing at Medford, n the county of Grant, Oklahoma, have lnve'nted certain new and useful Improvements in Auxiliary IVater-Heaters for Steam- Boilers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to water heaters for steam boilers, and it consists in the construction and arrangement of parts, as will be hereinafter described and particularly pointed out in the claim.

In the accompanying drawings,Figure 1 is a plan view of a boiler provided with my auxiliary water heater; Fig. 2 is a longitu dinal sectional view out on the line 22 of Fig. 1 looking in the direction indicated by the arrows; Fig. 3 is a detail view of a slightly modified form of the water heater, showing its intermediate portion built up of a number of hollow tubes connected at adjacent ends by return couplings.

As shown in the drawings, the numerals 1, 2, 3 and 4 indicate respectivel the water chamber, heat fines, and smo e box and stack of a stationary steam boiler.

5 indicates the auxiliary water heater which is preferably made from one continuous piece of hollow tubing communicating at one end with the water chamber of the boiler extending forwardly on the outside of the same to a point near the inner end of the smoke box through which its intermediate portion 5" extends in a zigzag form or fashion. One end of the latter formation of said tube is connected to the boiler, as at a, the opposite end thereofbeing bent back and forth laterally in o posite directions with respect to the axis of the boiler to form a plurality of parallel tubes, the free end of said heater extending out of the front end of the smoke box and thence rearwardly along the outside of the boiler so that it may be connected with a source of water supply when it is desirous to replenish the supply of water in the boiler. An upright support 6 of preferably inverted U -sha ed form is arranged in and longitudinal y of the smoke box under the water heater to support or maintain it in position.

Should I find it desirable in the construction and application of the invention I may Specification of Letters Patent.

Serial No. 376,994.

build up the intermediate portion of the heater, or in other words, that portion extending through the smoke box of the boiler of a number of hollow pipes or tubes 7 connected at their adjacent ends by return couplings S. This method of building up the intermediate portion of the heater enables it to be applied with greater facility in position. The intermediate or zigzag portion of the heater being arranged in the smoke box or in any other suitable position whereby it is subjected to the heating action of the products of combustion from the furnace, is maintained atahigh degree of temperature as long as there is fire in the furnace. When it be comes necessary to replenish the supply of water in the boiler the free end of the heater is connected with the source of water supply and the water caused to pass through the entire length of the heater before passing into the water chamber of the boiler.

By employing my improved auxiliary heater in connection with a steam boiler the products of combustion are utilized twice in raising the water to the required degree of temperature, and it necessarily follows that the fuel consumption is reduced to a minimum.

While I have shown and described my improved auxiliary heater in connection with a stationary steam boiler, I have done so merely for the sake of this specification, as it may be applied to a locomotive or any other steam boiler.

I wish it to be understood that my boiler is constructed in sections and at the joints of each section is provided bands I), arranged on the outside of said joints of the sections and bolted thereto so as to provide means for securing said sections together, the front and rear plates 10 and 10 respectively, of the heating and smoke chamber are flanged as at 10 so as to overlap the ends of the said heating and smoke chambers, said flanges being also provided with bands I), which are bolted thereto and to the flanges of the plates, and to ends of the heating and smoke chambers. Between the heating and smoke chambers I provide a )erl'orated flanged partition 10, which reinforces the meeting ends of the water and smoke chambers and also serves to support the inner ends of the heat flues 2 in said perforations, the outer ends of these lines being secured to perforations formed in the rear plate 10 of the heating chamber.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

A structure of the character described comprising sectional heating and smoke chambers, an auxiliary Water heater composed of a series of pipes located in the smoke chamber having a support for the same, an inlet pipe secured to the end of one of said pipes, and an outlet pipe secured to the end of another of said ipes, said sections of heating and smoke cffambers having their meeting ends secured together by hands, the outer ends of the heating and smoke chambers being provided With flanged lates Which overlap said ends and having bands bolted thereto and to said ends of the Water and smoke chambers, the plate of the Water chamber being perforated, a perforated flanged partition secured to the inner surface of the water and smoke chambers therein provided With perforations, said partition serving to reinforce the Water and smoke chambers and also serving as a support for the inner ends of the heating pipes which are connected to the perforations JACOB HOUSER.
