SPECIFICATION forming part of Letters Patent No. 554,499, dated February 11, 1896. Application filed fieptember 21, 1895. Serial No. 563,251. (No model.)
To all whom it may concern.-
Be it known that I, OSCAR SOHNIGGE, a subjeot of the German Emperor, residing at Berlin, Germany, have invented certainnew and useful Improvements in Regenerating-Furnaces with Devices for Ventilation and Circulation Heating; and I do hereby 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.
This invention relates to certain improvements in the construction of stoves and furnaces, whereby a thorough combustion of the fuel, as well as of all smoke and gases arising therefrom, is insured.
My invention further provides for a uniform temperature and perfect ventilation of the apartment in which the stove or furnace is located, as will be readily understood from the following description.
Referring to the drawings, Figure 1 is a vertical longitudinal section of a stove or furnace embodying my improvements. Fig. 2 is a vertical section at right angles to Fig. 1, and Fig. 3 is a horizontal section of same.
The casing A of the stove or furnace may be made of iron, bricks, tiles, or such other material as is commonly used for said purpose, and provided with a cornice and such other decorations as fancy may dictate.
The fireplace B is arranged in the lower part of the apparatus and is partially constructed with double walls and top, the space 0 between same forming a passage for the products of combustion, which enter the space 0 through openings d formed in the lower shell of the furnace-top and which escape therefrom through opening at the lower part of the furnace rear wall into a flue e, as indicated by arrows at e.
The bottom of the furnace is provided with an ordinary grate F, the front bearing-bar 7b of which serves as a support for a removable grate 2', which is adapted to fill the space between bearing -bar and the furnace-lining above same.
The bottom of the ash-pit K is provided across its front with a raised support on which rests an open-top water-tank Z for the purpose of supplying moisture to the burning fuel.
Fresh air is admitted at the bottom of the grate and to the hollow back of the furnace through the opening m and connecting-conduits 'n o, the supply of air being regulated by means of a suitable damper connected with said opening. The damper shown in the drawings (see Figs. 1 and 3) is composed of a plate 1 having a central screw-stud 2, adapted to operate in a cross-bar 3 at the front of the draft-opening; the said plate being provided with a handle 4 by which it is operated as desired.
Access to the interior of the furnace and to the ash-pit thereof is had through doors 5 6, as in other apparatus for a like purpose.
Above the furnace-top and in one of the rear corners of the apparatus is a vertical hotair flue '7, the upper part of which projects horizontally, as shown at 8, and communicates with the outside through a grating 9.
The upper part of the apparatus is provided at different elevations with horizontal plates 10, each plate having an opening 11 on one end thereof, and the plates so arranged that the said openings shall be at alternate ends of the compartment.
The apparatus is provided near its top with a smoke-exit pipe 12, and near its bottom with a side 13, in front of which is a. grating 14. A flue 15 extending rearwardly through the apparatus is provided with a regulating-damper 16. This flue may terminate within the compartment or be extended to the outside of the building within which the furnace is located and there protected by a grating or screen, as indicated at 17 in Fig. 3.
To heat the apparatus the grate 2' is first removed and an ordinary wood fire started on the grate F by introducing the kindling through the door 6. When the fire is fairly started, the grate 2' is replaced and the door closed, after which the coal' is introduced through the door 7. Air in the meantime is admitted through the opening m into the con-- duit n, where it takes up heat and is delivered into the ash-pit, from whence it passes upward through the grates F andt to the burning fuel. In passing around the bearing-bar h the air is brought in contact with the water contained in the tank Z, and in consequence passes to the fire in a moistened state, where,
coming in contact with the incandescent coal, it is decomposed andforms oxycarbon gas and hydrogen.
The products of distillation partly confined in the upper part of the fireplace, being unconsumed and having the form of smoke, pass through the openings into the hollow rear wall of the furnace through the space 0, after which it descends and combines or mingles with the products of combustion, passing from the fireplace through the flue e. The air passing from opening an through conduit 0 furnishes a great quantity of oxygen to the gases in the space 0. These gases on meeting the oxycarbon and hydrogen gases coming from the incandescent fuel on the grate are consumed, producing a bright flame without smoke.
The gases of combustion passing upward in the apparatus are forced to take a zigzag course through the openings, 11 in the plates 10, and in doing so gradually give out their heat, finally escaping through the pipe 12.
In order to derive the greatest amount of heat from the apparatus that side thereof which contains the hot-air fine 7 should be placed outward, so that the air can freely enter same and thus keep up a constant circulation in both room and apparatus until the diiference in temperature has been equalized.
Having fully described the construction and operation of my heating apparatus, what I claim as new, and desire to secure by Letters Patent, is-
1. In a heatingfurnace, a fireplace partially provided with hollow walls and top, the lower plate of the top, having inlet-openings as described and an air-flue communicating with the hollow space in the rear wall of the furnace, substantially as set forth.
2. The combination in a heating-furnace of a fireplace partially formed of hollow walls and top having inlets and exits for the products of combustion as described, the rear hollow wall constituting a mixing-flue with an adjustable air-opening and conduits for conveying the air, and discharging same, under the fire-grates and into the said mixingflue, substantially as set forth.
3. In a heating-furnace, the combination of a fireplace having hollow walls and top, provided with air inlets and exits, as described, with horizontal plates arranged at diiferent elevations above the fireplace, the said plates provided at alternate ends, with opcnin gs and the apparatus having an outlet smoke-pipe, substantially as set forth.
4. The combination in a heating-furnace of a fireplace having hollow walls and top, and air inlets and exits to the space within said walls, with a hot-air flue, as described, and grate-opening near the top and bottom of the apparatus whereby a circulation of evenlytempered air is secured, substantially as set forth and for the purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
