- Application filed February 9, 1898. Serial no. 669,676. (No mass.
To all whom it may concern:
Be it known that I, HENRY residing at St. Louis, State of Missouri, have invented certain new and useful Improvements inHot-Air Blower- Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.
My invention has relation to. improvements in hot-air furnaces; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.
- In the drawings, Figure 1 is a vertical-m iddle section on line 1 1 of Fig. 4'. Fig. 2 is a section taken at right angles to Fig. 1 on line 2 2 of Fig. 1. Fig. 3 is a horizontal section Fig; 1, and of the casing of the furnace? The object of my invention is to construct a hot-air furnace which shall expose a maxi,- mum heating-surface to the air-currents passing through the hot-air chamber thereof, one in-which a portion of such currents canbe utilized to force the draft through the combustion-chamber, one which while it possesses the advantage of presenting a large amount of heating-surface shall at the same time be compact,and one presenting further and othen advantages better apparent from a detailed description of the invention which is as follows:
Referringto the drawings, outer casing of the furnace, which constitutes the hot-air chamber 2. The casing is preferably rectangular in cross'secthereof being stifiened by an angle-iron 3. Formed in two opposite walls of the casing near the base thereof are two openings 1, within which are mounted.
forthe fansuit- 1 represents the shaft 6, the latter being provided with a able fan 7 within the casingand with a belt-" P ulley 8 outside the casing, motion being imparted to the pulley from any suitable source of power. (Not shown.) Extending from the front wall of the casing-that is, the wall adhich the fan-shaft is mounted-to within a suitable distance of the rear wall of the casing is a fire-box comprising a combustion-chamber 9,proper, and
BAETZ, a citi- 4 is atop'planthe interior of an ash-pit 10, the baseof the latter extending to a shortdistance from the edge of the fan-blades and being located directly over the latter. The combustion-chamber and ash-pit are provided with the usualdoors 11 and 12,-respectively.
.Mounted upon suitable supporting anglepieces 13 on top of the fire-box is a smokedrum 14., the said supports serving to raise the upper wall of the fire-box to permit of the free circulation of air throughthis space and vertical side walls of the combustion-chamber and drum, respectively, and establishing communicationbetween the interiors of said chamber and respectively, the former bustion-ohamber the fuel to the lower portion of the .drum and the latter from the upper portion of the combustion-chamber to the upper end of the drum. This multiplicity of flues serves to break up the ascending currents of air, permitting the latter to freely circulate among the pipes and around the drum, this arrangement exposing a large amount of heating-surface and thoroughly heating the air driven in by the fan; The drum is provided with an escape-flue 20, passing through the upper wall The latter is provided with hot-air pipes 17, which may conduct the warm air to any place where the same is needed. Passing throug the wall of the ash-pit and establishing communication between the same and the chamber of the casing is a longitudinally-slit box or leading from the commouth 19, the mouth 19 serving to collecta portion of the air-currents forced by the fan and direct them under the fuel to efiect a fogced draft. va ve or damper 21, operated by a rod 22 from withoutthe casing to close or open the mouth of the tube at will, such dampers and means of operating the same being of usual construction and no special claim being made thereon.
, It is apparent; that the present furnace is susceptible of minor changes without afiecting the spirit of my invention. instead of having a fan for forcing the air against the flues and drum it may draw the air,'in which event the relative location of around the drum. Connecting the adjacent tube 18, having an outer depending flaring.
the base of the drum a suitable distance above drum are uptake-flues 15 16,
at a'point irn'mediz'tt'elyoverof the casing.
The tube is provided with a For example,
The same can be coal, coke, wood, gas, and
the like. As seen from the drawings, the lengths of the pipes or flues 15 16 are the same, the alternating arrangement here shown being resorted to to better distribute the escape of the combustion products into the drum and to break up as much as possible the aircurrents coming in contact with the exterior of such pipes.
Having described my invention, what ll claim is- I 1. In a-hot-air furnace, a suitable casing, a fire-box mounted within the same and extending from the frontv wall thereof to within a suitable distance of the rear wall, a fan-shaft mounted in the side walls of the casing below the fire-box,
a drum mounted at a suitable distance above the fire box and extending 'rearwardly to within a suitable distance of the rear wall of the casing, a double series of flues alternately connecting the lower and upper portions of the adjacent vertical side walls of the combustion-chamber and drum respectively near a fan carried by said shaft,
the top and bottoms of said walls,ai1 escapeflue for the drum leading through the top wall of the casing, means for operating the fan-shaft, a tube leading from the chamber of the casing through the wall of the ash-pit and carried between the grate of the fire-box for directing a portion of the air-currents into the fire-box, and a valve for controlling the said tube, substantially as set forth.
2. In a hot-air furnace, a suitable casing, a fire box located within the same, a drum mounted over the firesbox, a multiplicity of lines having the terminals of one set disposed at a difiere'nt elevation from that of the other set, that is to say, breaking joint with one another in their points of connection with the fire-box and drum respectively, the casing being provided with openings for the admission of air into the air-chamber, substantially as set forth. v
In testimony whereof I affix my signature inpresence of two witnesses.
