UNITED STATES PATENT OEEIcE.
ANDREXV ANDERSON, OF HASTINGS, MINNESOTA, ASSIGNOR OF THREE.- FOURTIIS TO GEORGE PARKER AND ALFRED E. JOHNSON, OF SAME PLACE.
HOT-AIR STOVE OR FURNACE.
SPECIFICATION forming part of Letters Patent No. 556,913, dated March 24, 1896. Application filed January 8, 1895. Serial No. 534,236. (No model.)
To all whom it may concern.-
Be it known that I, ANDREW Annnnson, of Hastings, Dakota county, Minnesota, have invented certain Improvements in I-Iot-Air Stovesor Furnaces, of which the following is a specification.
My invention relates to improvements in hot-air stoves and furnaces; and it consists in the features of construction more particularly described and claimed.
In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of the furnace, partially broken away to show the interior construction; and Fig. 2 is a cross-section of the same on line a: a; of Fig. 1.
In the drawings, A represents the fire-box of the furnace, provided with a grate 2 of the ordinary construction and having corrugated inner Walls 3.
represents a cold-air chamber over which the furnace is supported upon the pillar 5, air being admitted to the chamber by means of the air-duct 6.
Between the inner wall,7,of the furnace and the outer inclosing wall, 8, is a space 9 communicating at its bottom with the cold-air chamber and opening into the hot-air chamber 10 at the top of the furnace.
Communicating with the cold-air chamber 4; on each side of the firebox are the pipes or conduits 11 and 12. These pipes lead up be tween the sides of the fire-box and the inner wall of the furnace, and are arched over the top of the fire-box, terminating in the cylindrical tube 13, which in turn opens into the hot-air chamber 10. Air is admitted to the fire box to feed the fire through the drafts 15 in the furnace-door.
The smoke and other products of combustion passing from the fire-box A encircle the pipes 11 and 12 and the tube 13 on their way to the outlet-pipe 16, heating the contained air, and also come in contact with the inner walls of the furnace, heating the air passing through the space 9. The heated air is carried from the hot-air chamber to wherever it is to be used by means of the pipes ll.
I claim- 1. In a hot-air furnace, in combination with the cylindrical inclosin g wall, the oblong fire box, the cold-air chamber underneath, and the hot-air chamber above the same, the pair of air-ducts oblong in cross-section interposed between said wall and the long sides of said fire-box and in contact with the Wall or casing of the fire-box so as to be heated by the heat conducted through said casing, said air-ducts communicating with the cold-air chamber and arching over said fire-box, and the common flue connecting them with the hot-air cham ber.
2. In a hot-air furnace, the combination with the oblong fire-box, the hot-air chamber above and the cold-air chamber below the same, of the pair of similar air-ducts oblong in cross-section extending down upon either side of said fire-box and covering the side thereof to prevent cracking and burning out, said ducts ending in an arch above said firebox and leading to the hot-air chamber, and the air -duct extending down around said fire-box outside of said oblong air-ducts and heated by the heat conducted through said ducts and the inner wall of the furnace.
3. In a hot-air furnace having a cold-air chamber at the bottom, and a hot-air chamber at the top, and made up of double walls with an intermediate air-space serving as an air-duct to connect said air-chambers, the combination therewith of the fire-box arranged above said cold-air chamber, the airducts adjacent the side walls of the fire-box and arching over the same and connecting said cold-air chamber with said hot-air chamber, whereby the heat conducted through the side walls of the fire-box serves to heat the air passing through said air-ducts, and the heat conducted through the inner wall of the furnace serves to heat the air passing through the space between it and the outer wall.
In testimony whereof I affix my signature in presence of two witnesses.
ANDREW ANDERSON.
