AIR-FEEDING DEVICE FOR FURNACES.
SPECIFIGATION forming part of Letters Patent No. 479,022, dated July 19, 1892.
Application filed December 21, 1891- Serial No. 415,763. (No model.)
To a/ZZ whom it may concern.-
Beit known that I, HERMAN H. E. SCHOM- BURG, a citizen of Germany, residing at Berlin,in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvementsin Air-FeedingDevicesfor Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled iu the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to air-feeding devices for furnaces.
The object of the invention is to provide means whereby the fire may be partially or wholly extinguished from the exterior of the heating apparatus or boilerwithout necessitating the opening of the tire-doors for this purpose. Y
A further object is to provide means for regulating the amount of air fed to the lower grate-bars,whereby the furnace may be cooled at will. Y
The invention consists in the improved construction and combination of parts 0f an air-feeding device, as will be hereinafter fully described and claimed.
In the accompanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, Figure l is a transverse sectional view through the fire-box of a boiler or a furnace. Fig. 2 is a similar View showing a modification of the construction shown in Eig. l.
Referring to Fig. l of the drawings, Adesignates the shell or casing of the re-box of a furnace; B, the feed-chute; C, the upper grate-bars, which extend obliquely downward from the said chute, and D E the lower gratebars. As these parts may be of any preferred construction, a detailed description of them is deemed unnecessary;
F designates a water box or tank, which is preferably of a'size to iill the entirewidth of the fire-box. This tank is pivoted at its rear end upon a bar f, secured at each end in the walls of the tire-box, and is supported at its front end by means of a chain G, which passes over a pulley H, and thence around a drum I, carrying ratchet-and-pawl mechanism whereby to hold the tank at any desired adjustment. The tank is pivoted in such relation to the lower grate-bars D E that when it is filled with water and is at its highest raised point, as shown in full lines, they will be submerged, and when the tank is at its lowest point the said bars will be free from the water, as the lowering of the tank causes the water to run out, a cock J serving to till the tank with water when emptied.
In the operation of the apparatus above described the raising of the tank only extinguishes the fire in the lower portion of the iire-box-that is, when there is a large fire in the fire-box-and at the same time the current of air through the upper grate-bars C vwill be materiallyL reduced as the spaces between the bars are closed by the Water, so that the furnace may readily be cooled when desired. The water-tank also serves as an ash-receptacle, as will be readily understood by reference to the drawings.
In Fig. 2 the same general arrangement of fire-box is shown as that illustrated in Fig. l. The main difference lies in making the watertank stationary and in having the grate-bars to raise or to lower by a chain and drum operating like that already described. By this means the same object is attained in both constructions.
I-Iaving thus fully described my invention,
what I claim as new, and desire to secure by Letters Patent, is-
l. The combination, with the fire-box of a furnace or the like, of a Water-tank and gratebars occupying a position normally without the tank and adapted to be submerged in the water, substantially as described.
2. The combination, with the fire-box of a -furnace or the like, of a pivoted water-tank and grate-bars adapted to be submerged in the said tank, substantially as specilied.
3. The combination, with the fire-box of a furnace 0r the like, of a pivoted water-tank, grate-bars adapted to be submerged in the said tank, and mechanism for raising or lowering the tank, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
HERMAN H. E. SOHOMBURG.
