LOUIS S. SEALLONE, 0F DENVER, COLDRADO.
Application filed February 2, l1927?..
To @NWC/ont if may concern.:
Be it known that l, Louis il. SrALLoNn. a 'citizen of the United States, residing at the city and county of Denver and State of Colorado, have inventedcertain new and useful `lmprovenient's in? Furnaces; and l do declare the following to he a full. clear, and exact description of the invention, euch as will enable others skilled in the to which it appert-ains to make and use the samel reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this speciication. v
This invention relates to furnaces, and has special reference to improvements in hot air furnaces.
In many of the furnaces in common use the heat isnot utilized to its fullest value, dueto the fact that no special eifort has been made to obtain a good thermal etliciency. i
It 'is the object of this invention to produce a furnace that shall-` be of simple and substantial construction, which shall have a high thermal efficiency, and which shall be comparatively cheap to manufacture.
In order to attain the above objects, l construct my furnace in the manner which l will now describe in detaih reference being had for this purpose to the accompanying drawing in which Fig. 1 shows a front elevation of my furnace, with parts broken away to show the construction and relative arrangement of parts;
Fig. 2 is a vertical section taken on line 2 2, Fig. 1;
Fig. 3 is a tA ansverse section taken on line 3--3, Fig. l;
Fig. -l is a transverse section taken on line @-4, Fig. 2; and
Fig. 5 is a view isters.
The same reference numerals will be used to indicate the same or similar parts throughout the several views.
Numeral 1 represents the outer casing or drum of my furnace, and 2 an inner drum, while 5 is the combustion chamber at the lower end of which is located the lire pot 41 and grate 5, below which is the ash pan 6. A passage 7 leads from the outside of drum 1 to the ash pan, and the front thereof is closed by a door 8. A door 9 closes the outer end of a passage 10 which leads to the fire of one of my hot air regr renuncia 'Serial Nov 533,531.
and directly above passage l0 is a third 1l whose front end is closed by a Fuel is introduced through the loor and pa e'e 10 and the gases and proc ucts of combustion leave through passage 11 and enter the helical flue 13 which res one or more complete turns about the upper end of the combustion chamber. after which it passes to point centrally of the furnace where it extends out and intothe chimney 14.
l want to call especial attention to the fact that the gas flue 13 has its inception at a point directly over the .feed door entrance, as
* riis location/of the flue seems to result in better and more thorough combustion, and besides, it permits the clean-out door 12 to be placed vertically over the feed door 9 and the door 8 which leads to the ash chamber, thus resulting in a convenient and pleasing arrangement.' lnner drum 2 is spaced from thev of the out-r drum 1 by means of clrets and lower edge terminates a short distance from the base 16. in order that air may pass from the space 17 between drums 1 and 2 and to the inside of drum 2. where it will come in Contact with the hot due 13 and the heated surface of the combustion chamber f3.
Near the tops of drums 'l and 2 l secure my hot air pipe 13 and the return cold air pipe 19, the former opening into the space within drum 2 and the latter opening into space 17. Hot air pipe 18 is smaller than pipe 19 and is held centrally of the latter by means of spacers 20.
ldlithin the rooms to be heated the pipes 18 and 19 are connected to specially designed register 21 which has a central opening 22 through which the hot- .air coming through pipe 18 enters, and a space 23 through which the cold air enters into the space between the two pipes for return to the space 17 in the furnace, from whence it passes downwardly until it reaches the lower edge of drum 2., after which it flows upwardly and into the hot air pipe 18, all as indicated by arrows in Fig. 1, It will be seen from the ahove that in my furnace a continuous circulation of air takes place in the room, and that the cold air near the floor passes downward into the furnace, and in doing so it becomes heated to some extent from contact with pipe 18. Within drum 2 and between it and the combustion chamber 3 the air impinges on the hot Hue 13 and becomes highly heated, with the result that y a high thermal efficiency is obtained.
ln Fig. i l have shown a section which illustrates the manner in which drums l and 2 are spaced by member l5 and in which drum 2 is spaced from the combustion chamber 3 by means of spacers 24. 0n either side of my grate 5 ,lf provide dampers 25 which have attached thereto a rod 26 by means of which they may be opened and closed. When the ashes are removed or the i'ire shaken down, then the dampers 25 should be opened, permitting the ashes to pass upwardly into the combustion chamber instead of into the furnace room, as is usually the case.
From the above it will appear that I have provided a hot air furnace that is simple in its construction and adapted to operate at a high degree of thermal efficiency, and which can be manufactured and installed at a moderate cost. My furnace as pointed ont above is so designed that it will remove the cold air 'from near the floor of the rooms at the same time that the hot air enters, and thus provide a steady circulation of air, which will also insure that the room will be heated regardless of the direction of the Wind outside or the relative air pressure in the various rooms to which the furnace is connected.
Having now described my invention, what I claim as new isl. A furnace comprising in combination a central combustion chamber, a drum surrounding said chamber and spaced therefrom, an outer drum surrounding said last named drum and spaced therefrom, a fire pot in said combustion chamber, a feed entrance opening into said chamber, a gas flue opening located directly over the feed entrance, a gas flue connected to the last named opening, said flue extending helically around the upper portion of the combustion chamber, and an air passage from the space between the two drums and the space surrounding the combustion chamber.
2. A furnace comprising in combination a central combustion chamber, a drum surrounding said chamber and spaced therefrom, an outer drum surrounding said last named drum and spaced therefrom, a fire pot in said combustion chamber, a feed entrance opening into said chamber, a gas flue opening located directly over the feed entrance, a gas flue connected to the last named opening, said flue extending helically around the upper portion of the combustion chamber, an air passage from the space between the two drums and the space surrounding the combustion chamber, and a pipe leading from the upper end of the inner drum to the room, and a pipe surrounding the first named pipe and spaced therefrom and extending from the space between said drum to the room.
In testimony whereof I affix my signature.
