To @ZZ whom, t may concern:

Be it known that I, CHARLES THOMAS WISE, Sr., of New Bridge, in the countyof Union and State of Oregon, have invented anew and Improved Heater, of which the following is a full, clear, and exact'description.

The object of the invention is to provide a new and improved heaterwhich is simple and durable in construction, serviceable as a hot air or water heater in the form of a stove, furnace, boilers, drying apparatus, or the like, and arranged to utilize the fuel to the greatest advantage.

The invent-ion consists of novel features and parts and combinations of the saine, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the improvement arranged as a hot-water heater. Fig. 2 is a sectional side elevation of the same on the line 2 2 of Fig. 3. Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2. Fig. 4 is asectional side elevation of the improve! ment arranged as an air-heater, and Fig. 5 is an enlarged side elevation of part of the saine.v

The improved heater, as shown in Figs. 1, 2, and 3, is provided with a casing A, supporting a tank B, adapted to contain water to be heated, the lower end of said tank being connected with one end of a pipe O,- extending in a longitudinal direction in the casingA to the forward end thereof, to be then formed into a coil C', arranged centrally in the casing, and preferably round or square in form. The rear end of the coil O terminates in a horizontally-disposed coil O2, located in the upper portion of the casing A, and the end of said coil passes through the casing'and extends up and down around the casing to form connected radiators C3 through which circulates the water or other heating medium for giving off heat to the surrounding air in the room. The end O4 of the last radiator Os returns into the tank B, so that the water is circulated from the tank through the several 5o parts of the pipe C and back to the tank.

The latter is provided on its top with a illing-cap D and with a safety-valve E, to allowi steam to escape in case it is formed.

The coil C is surrounded by a jacket formed bya shell F, attached at its forward end to a cap G for closing the front end of the casing A, and on the said cap Gis arrangedaiiringdoor l-I for introducing the necessary fuel into the fire-box formed by the said coil O. The inner end of the shell F terminates on a transverse partition or iiange J, located at the end ofthe coil O'. rlhe object of the jacket is to confine the heat to the iirebox to better control the draft and to guard against leakage of ashes, coal, dac., should the layers of the coil C spring apart or become displaced by the heat of the burning fuel.

If the heater is to be arranged as an air- 'heater, as shown in Figs. 4 and 5, then the .of the last radiator O3 terminates in branch pipes O5 O6, provided with valves O7 and C8, respectively, and passing into the forward end of the casing. The branch pipe O5 then eX- tends longitudinally in the coil O/ along the upper portion thereof to terminate in a downward bend O9, opening into the forward end ot' the tire-box to supply the latter with air for the proper combustion of the fuel. The other branch pipe CG discharges air into the forward port of the casing at or under the coil O2. Now by opening the valve C,T and closing the valve C8 the air passes to the firebeX, and by closing the valve O7 and opening the valve OS the air passes to the front end of the casing. In either case the air discharged by the pipes C5 and C6 serves to aid combustion and regulate the draft.

The rear end of the casing A is provided with a chimney-fine L for carrying off the smoke and gases, and in the rear end of the shell A is also arranged a door N for giving access to the interior of the casing and reF box for cleaning the same whenever desired.

Now it will be seen that by the arrangement described the fuel in the fire-box formed by the coil O thoroughly heats the water or IOO air flowing through the pipe C and coil C' to establish a circulation of the heating medium, as previously explained. As the heated air or water circulates through the radiators C3 a large amount of heat is given o to the surrounding air, so that the room in which the heater is located is very quickly and thoroughly heated With a comparatively small expenditure of fuel. It' desired, proper connection can be made With` the pipe forming the radiators C3 for leading the heated air or water to a distant place for supplying a radiator there.

A draft-pipe similar to the pipe C5 is preferably made use of in the Water-heater to supply the fire-box C with fresh heated air to aid combustion.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. A heating apparatus having a casing, a jacket located in the casing and separated from the walls thereof, and occupying a portion of the space Within the casing, and a fluidcirculating tube extended into the casing through the jacket thereof and formed into a vertical coil Within said jacket, the tube being extended from said vertical coil to the front portion of the casing and being there formed into a horizontal coil, from which horizontal coil the tube passes without the casing and is bent-into vertically-disposed loops eX- tending around the casing to form connected radiators.

2. A heating apparatus having a casing, a jacket situate therein and occupying a portion of the space therein, the jacket being separated from the walls of the casing, a tube extended into the casing and through the jacket thereof, the tube being formed into vertically-disposed coils within the jacket and being extended from said jacket to the frontof the casing and formed into horizontallydisposed coils from Which the tube passes Without the casing and is formed into vertically-extending bends forming radiators eX- tending around the casing,the end of the tube being formed into two branches returned into the casing and discharging, the one into the coil of the jacket, and the other beneath the horizontal coil of the casing, and valves respectively commanding the said branches.
