HEATING STOVE USING VARIOUS KINDS OF FUEL Filed Dec. 30, 1953 INVENTOR. CLYDE D. BUCK Elk/2% ATTORNE) HEATING STOVE USING VARIOUS KINDS OF FUEL Clyde D. Buck, Fremont, Ind.

Application December 30, 1953, Serial No. 401,247

1 Claim. (Cl. 126-110) This invention relates to heating stoves and more particularly to a stove wherein, by means of a suction fan will direct the heat downwardly toward the floors for warming the same.

Under the usual home conditions, especially where there are small children in the family, it becomes a necessity to keep the air close to the floors warmed. The children are constantly playing on the floor and the present day heating systems tend to leave the air close to the floor cooler than the air at a higher level.

Persons sitting down for an evenings relaxation often complain of drafts and cool air layer-s close to the floor and such conditions create discomfort and subsequent illness.

The main object of the invention, therefore, is to pro vide a stove that will heat the area close to the floor and overcome the discomfort that arises from the conventional heating systems of today, failing to properly heat such area.

Another object of the invention, therefore, is provide a stove of simple design, having downwardly inclined fins that will trap and force downward any air drawn into the stove by means of a suction fan.

A further object of the invention is to provide a stove of this type that can be adapted to use fuel of various types, such as coal, oil or gas. However, it has been found more practical to heat the stove with oil or gas.

With these and other objects and advantages in view the invention embodies a housing, which may be of any shape or size, a plurality of downwardly inclined flanges disposed in the housing in spaced relation to each other, a fire pot within the housing intermediate of the fins, a plurality of air conduits, one within and enclosed by each flange, means for drawing cold air into the air conduits for the heating thereof and means for heating the indrawn alr.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing wherein:

Fig. l is an elevational view partly in section illustrating an embodiment of the invention;

Fig. 2 is a cross-sectional view on the line 2--2 of Fig. 1; and

Fig. 3 is a cross-sectional view of the stove forming the invention showing in elevation one of the air conduits.

Referring now to the drawing wherein like reference characters denote corresponding parts, the stove of this invention includes a housing or shell which may be of any size or shape, but for purposes of illustration, is depicted of cylindrical formation. The housing 10 may be of the well-known grille construction or it may be perforated, as indicated at 9, in any manner to permit heated air to escape therefrom. The housing 10 is slot- 2,898,904 1 Patented Aug. 11, 1959 ted at intervals to form air openings, so that outside air can enter into the housing and denoted by reference character 10a.

Secured to the upper end of the housing is an angle iron 11 on which is mounted the top 12 of the housing. The top conforms to and rests upon the peripheral edge of the housing. The bottom of the housing remains open and is positioned on a surface 13, such as a floor or other surface wherein the air adjacent such surface is desired to be heated.

Positioned within the housing 10 is a fire pot or box 14 and such fire pot will conform in contour to the housing 10 and in this instance being of cylindrical formation. The fire pot is provided with a chimney 14a which extends through the housing 10 in conventional manner.

The fire pot is provided with vertically disposed, relatively spaced legs 15 which are secured at their lower ends to a dome shaped supporting member 16. The legs 15 and member 16 space the fire pot from the floor 13.

In the particular embodiment of the invention disclosed, oil heat is provided for heating the s tove and a reservoir tank 17 is provided for an adequate supply of oil. The tank is of conventional design and is supported on the housing 10 by means of brackets 18.

A conduit 19 is connected to the tank and a control valve 20. The control valve 20 is also of conventional design and supplies the fire pot with oil by means of a conduit 21. The control valve 20 is operated to control the intensity of the fire within the fire pot. A bracket 22 secured to the housing 10 supports the control valve thereon.

Secured to the fire pot 14 in relatively spaced relation to each other is a plurality of truncated conical shaped flanges or fins 23 which are directed downwardly toward the lower end of the housing 10.

Within each flange and encircling the fire pot 14 is a horizontally disposed perforated air pipe 24 and each pipe is provided with a perforated conduit 25. Each conduit assumes the inclination of the downwardly directed flange with which it is associated and is connected to a vertically disposed common conduit 26 by means of outwardly and downwardly extending horizontally disposed extensions 27. An outwardly extending, horizontally disposed extension 23 on the lower end of the common conduit 26 is connected to a conventional suction fan 29. The fan 29 rests upon th floor 13 in close proximity to the housing 10.

In operation, the oil within the fire pot is ignited in the usual manner and after the pipes 24 have been sulficiently heated, the fan 29 is activated to draw the cold air from the area close to the floor. The air forced through the common conduit 26 is eventually dispelled from the perforations in the air pipe 24. Having passed through the pipes, which have been heated by their close proximity to the fire pot, the air is dispelled in a downward direction toward the floor by means of the flanges 23.

Thus, the cool air close to the floor is drawn into the stove, heated and then directed onto the floor in its heated condition. The air close to the floor is therefore main tained at a comfortable temperature to dispel any discomfort created by the cold layer of air so often found closed to the floor.

It will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention and the scope of the appended claim.

Having thus described the invention what is claimed to be new and desired to be protected by Letters Patent is:

A stove comprising an outer cylindrical casing having a closed top and open bottom, an inner cylindrical fire pot in said casing, means for supplying fuel to said fire pot, a plurality of perforated pipes surrounding said fire pot in vertically spaced relation, a common air supply pipe for said perforated pipes, means for introducing air under pressure to said supply pipe, and a plurality of truncated comically shaped flanges each mounted on said fire pot immediately above one of said perforated pipes, whereby to direct air from said perforated pipes downwardly toward the bottom of said casing, said casing being spaced vertically from a supporting surface to permit entrance of air to the interior of said casing.
