UNITED STATES .LLBEBT VOBHEES GULVER, OF FRANKFURT, INDIANA.
FURNACE.
Application 11151 August a, 1925. .Serial No. 47,894.
My said invention relates to a furnace here illustrated as being of the pipeless type and it is an object of the same to improve the heating action of the furnace and the circulation of airwhile decreasing the amount of fuel required. My invention is, however, not limited .to furnaces of any especial variety, but extends to furnaces and heatenerating plants in general.
Re erring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts,
Figure 1 is a front elevation of my device with parts broken away, and
Figure 2, a section on line 22 of Figure 1.
In the drawings reference character 10 indicates the outer jacket or casing of the furnace here shown as extendin from the floor A up to the floor 11 of the uilding in which the furnace is used. An inner jacket 12 is mounted within the casing 10 and extends from the floor 11 to a point adjacent the floor A and surrounds the furnace proper or other fire container 13 which is provided with an ash pit door 14, a fire door 15 and an outlet 15' for smoke.
The principal feature of the invention consists in omittin -all drafts and draft openings from the oors and from the front of the furnace. To provide the necessary draft I have arranged dampers 16 in the door frame or extensions 17 of the furnace wall at opposite sides of the door space. It will be readily seen that when these dampers are opened air will be admitted to the space boneath the grate in sufficient quantity to maintain combustion. This air is taken from the circulation through the building coming down through the space between the inner and outer jackets and diminishing, to the slight extent indicated, the amount of air passing up between the inner jacket and the furnace proper.
A air of pipes 18 are provided at opposite sides of the door space between the furnace proper and the inner jacket 12 which pipes are adapted to receive air at their lower. ends in similar manner to the openings just described and at their upper ends admit it to the space above the grate in well-known manner so as to keep the fire from going out when the dampers 16 are closed. Dampers 19 are provided in the pipes 18 and these dampers have a crank handle 20 at the outside of the furnace by means of which the dampers 19 may be opened to various degrees or closed at will for opening and closing the passages through the pi es 18. A cord or cable 22 leads upward om the righthanddraft 16 to a point in the room above or adjacent thereto, and a similar cable leads from the other draft 16 over a pair of pulleys23, 24'
to the first-named cable so that both lower drafts can be operated without entering the furnace room. In similar manner the dampers 16 have a handle at 21 whereby they may be operated. It will be seen that the draft to the space above the grate may be opened or closed independently of the draft to the space below the grate thus providing for all the usual draft variations by which the fire is controlled.
Instead of drawing the air for the fireor other chamber in which the furnace is located it is drawn from the lower heated part of the building heated by the furnace and so improves the circulation in the building. The air in the building being preheated does not require so much heatlng as the cold air ordinarlly used and thus reduces the amount'of fuel required for maintaining the desired temperature in the building.
It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims. It will also beobvious how my invention can be applied to furnaces and heat-generating plants of other types than the pipeless furnace here depicted.
Having thus fully described my said invention what I claim as new and desire-to secure by Letters Patent is:
1. The, combination in a pipeless furnace of a fire box, inner and outer casings for the fire box terminating in the door frame said door frame having openings in its sides near the bottom below the level of the grates for admitting air directly below the grates, closures for said openings said door frame also-having openings in its sides near the top above the level of the grates for admitting air directly above the grates, and
box from the outside or from the basementmeans for graduating the flow of air through said last-mentioned openings, substantially as set forth.
2. The combination in a pipeless furnace of a fire box, inner and outer casings for the fire box terminating in the door frame said door frame having openings in its sides near the bottom below the level of the grates for admitting air directly below the grates, closures for said openings said door frame also having openings in its sides near the top above the level of the grates for admitting air directly above the grates, pipes having their upperends secured about the last-mentioned openings and terminating at substantially the same level as the firstmentioned openin s, and means for graduating the flow of air through said pipes, substantially as set forth.
3. The combination in a of a fire box, inner and outer casings for the firebox terminating in the'door frame said door frame having openings in its sides near the bottom below the level of the grates for admitting air directly below the grates, closures for said openings said door frame also having openin s in its sides near the top above the leve of the grates for admitting air directly above the grates, pipes,
having their upper ends secured about the last-mentioned openings and terminatin at substantially the same level as the tmentioned openings in the path of the "010- sures for said first-mentioned openings whereby said closuresmay be operatedv to cut off the air supply to either the upper or the lower openings, substantially as set forth.
In witness whereof, I have hereunto set my hand and seal at Frankfort, Indiana, this 24th day of July, A. D..nineteen hunpipeless furnace dred and twenty-five.
