FURNACE.
SPECIFICATION forming part of Letters Patent No. 459,675, dated September 15, 1891.
Application filed March 19, 1891. Serial No. 385,648. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM L. CARTER, a citizen of the United States, residing at Cedar Falls, in the county of Black Hawk and State of Iowa, have invented a new and useful Furnace, of which the following is a specification.
This invention relates to hotair furnaces; and the objects in view are to provide a fur- 1 nace to consume'a minimum amount of fuel with an internal flange or base-ring 2, having its inner edge downwardly turned or flanged, as at 3, while the upper end of the shell is provided with a crown 4. The crown and the base-ring or internal flange 2 are provided along their outer edges with semicircularshaped openings 5, which are connected by tubes 6, open at their upper and lower ends, and therefore extending along the inner surface of the shell 1, where they may be acted upon by the products of combustion. The shell thus constructed is provided with a suitable fuel-opening 7, diametrically opposite the same, with an uptake or pipe-opening 8, and the whole is seated upon a suitable base comprising the usual ash-pit 9. To the uptake" or pipe-opening 8 is connected the lower end of a convoluted or coiled pipe 10, which passes around the conical shell 1 and terminates in a chimney, into which the products of combustion pass after having passed through the pipe. At intervals below the ter minat-ion of the pipe said pipe is tapped, and branch pipes 11 pass into the chimney, and they, together with the end of the pipe, are provided with dampers 12. The entire furnace thus constructed is surrounded by a suitable jacket 13, to which are connected the 10, the whole surface of which is inclosed by the jacket, and also radiates from the conical shell and its dome, and the cold air passes up through the hot-air pipes 6 and is warmed by radiation and emptied into the jacket, from which it passes off through the heat-pipes to the points of use. It will be observed that by opening all of the dampers 12 the draft is increased to the utmost and the fire intensified, and by closing the drafts or one or more of them the fire is cooled or decreased, so that in this manner the heat may be regulated. Hand-holds 14 are provided with caps andlocated in each of the coils of the pipe 10, whereby the coils may be readily cleaned of soot, dust, &c. The dome, being of frustum shape, throws the'fiues over the fire, and thus they are more directly exposed to the heat and radiate a greater amount of heat than if vertical. At the same time they and the coils are disposed in an inclined manner, and consequently offer but little obstruction to the free passage of heat therethrough.
Having described my invent-ion, what I claim is 1. In a hot-air furnace, the combination, with the inner and outer shells, of a coiled pipe leading from the inner shell, coiled about the same and terminating in an uptake, and a series of branch pipes located upon each coil and communicating with the uptake, substantially as specified.
2. The combination, with-the outer shell, the heat-pipes connected therewith, and the conical inner shell, of the pipe connected to the inner shell, coiled about the conical shell. and projected through the outer shell, where it communicates with the chimney or uptake, and the series of branch pipes, one leading from each coil and all provided with dampers, substantially as specified.
3. In a hot-air furnace, the combination, with the outer jacket and the inner conical shell provided with a perforated dome and at its lower end a base-ring having openings corresponding to those in the dome, the pipes connecting said openings of the dome and ring, of a coiled pipe communicating with the inner shell and passed around the same and terminating in a chimney, substantially as specified.
4. The combination, with the outer shell, the heat pipes connected therewith, and the conical inner shell having a series of tubes which are open at the top and bottom and arranged along the inner side of the shell, of the pipe connected to the inner shell, coiled about the conical shell and projected through the outer shell, Where it communicates with the chimney or uptake, and the series of IO branch pipes, one leading from each coil and all provided with dampers, substantially as specified.
In testimony that I claim the foregoing as my own I have hereto aifixed my signature in presence of two Witnesses.
