PROC'IOR COOLEY, OF PEORIA, ILLINOIS, ASSIGNOR TD OULTER 6: PROCIOR STOVE (30., OF PEORIA, ILLINOIS, A CORPORATION OI ILLINOIS.
SOFT-COAL BURNER.
Application filed November 18, 1910.
To all whom it may concern:
Be it known that I, PRoo'ron P. CooLEY, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Soft-Coal Burners, of which the following is a specification.
This invention has reference to stoves and relates particularly to what may be known as a down-draft soft coal base-burner.
One of the objects of the present invention, is to improve the magazine type of soft-coal burners, by constructing the fire pot wall with flue-openings and so arrange the dampers in the back-flue that the products of combustion may be caused to ascend through the fire-pot and out through the flue, or pass out through the flue openings in the wall of the fire-pot and down and through a flue in the base of the stove and thence out through the back-fiue The invention has for a further object to improve the magazine type of soft-coal burners, by arranging the dampers in the back-fiue and so constructing the wall of the fire-pot, that the gases will be directed from the lower end of the magazine, thereby preventing the burning of the coal at this point and expansion of such coal to clog the outlet of the magazine; the gases being caused to descend around, preferably the front-half portion of the fire-pot, into and around the base of the stove and pass to and out the back-flue.
Further objects and aims of the invention will become apparent from the following description' and drawings forming a part thereof, in which Figure 1 is a vertical sectional view of a form of stove with my improvements applied thereto; Fig. 2 is a cross-section through the base, on the line 2-2 of Fig. 1; Fig. 3 is a cross-section through the stove just above the grate-bars, or on the line 3-3 of Fig. 1; Fig. 4 is a cross-section through the stove just above the fire-pot, or on the line 1-4 of Fig. 1; Fig. 5 is a cross-section of the stove, through the magazine, or on the line 55 of Fig. 1, and Fig. 6 shows a modified construction of the fire-pot, shown in Fig. 1.
Like characters of reference denote corresponding parts throi'ighout the figures.

1 designates the outer shell or casing of the stove, which may be of any suitable construction and the stove generally, of any preferred design and round or square.
2 is the coal magazine depending from the top of the stove and surrounded by an air or combustion chamber 3 and suspended within the magazine 2, is a preferably tubular member l having the lower coneshaped or flared portion 5 intended to retard the progress of the coal through the magazine. The cone-shaped or flared portion 5 preferably protrudes from and below the lower end of the magazine, with its lowermost edge approximately flush with the top edge of the fire-pot 6.
The fire-pot 6 is preferably frusto-conical and seated or supported on a supporting ring 7, said ring conn cted with the shell or casing of the stove by webs 8. The forward web extending approximately across the full width of the stove and between said webs are left flue-openings 9, see Fig. 3, communicating with the lower or base portion of the stove. The fire-pot G is supported with the larger portion of the cone on the ring 7, which is just the opposite of the manner of supporting or carrying the usual or ordinary fire-pot, and the smaller or upper end of said fire-pot 6 is formed with an up wardly and outwardly extended flared wall 10 supporting a depending annular ring or wall 11 provided with a radial flange 12 which rests on or engages a ring 13 from the wall of the stove for sustaining the upper end of the firepot in its normal position. The wall of the main body portion of the fire-pot 6 is provided with a plurality of slots 14 and 15 having a staggered relation and the wall 10 and annular ring 11 of said fire-pot are provided with perforations 16 and 17, respectively. I prefer to arrange the slots 14 and 15 and perforations 16 and 17 in the fire-pot around the front half portion thereof, that the gases passing out of the fire-pot will pass around the forward half portion of the stove. The firepot is surrounded by a chamber 18. The openings ll and 15 are arranged in staggered relation and are made elongated for the purpose of allowing the gases to escape readily from the firepot.
The grate bars are designated 19 and may be of any well known or approved construction.
20 designates a base-flue lining, see Figs. 1 and 2, which serves as the wall of the ashboX 21 and being spaced from the wall of the stove produces a flue 22 which is in communication with the chamber 18 surrounding the fire-pot, through flue openings 9.
23 designates a combined flue and basestrip depending from and carried across or around the forward portion of the stove, see Fig. 1. The flue 28 communicates with the flue 22 at its forward ends, as at 241-, see Fig. 2.
A door 25 may be provided forming a communication with the chamber 8, and a door 26, having a suitable valve or damper, not shown, may form a communication with the ash-box 21. The magazine 2 may be covered in any suitable manner and provided with means forming an easy access to said magazine 2.
25 designates a back-flue, in communication with the flue 22, in the base of the stove, through an opening 26 and also adapted to be in communication with the chamber 3, through an opening 27. The opening 26 is adapted to be closed by a valve or damper 28 and the opening 27 is adapted to be closed by a damper or valve 29. The valves or dampers 28 and 29 are operatively connected by a rod 30, which will operate to automatically close either valve when the other is opened. For operating the valves, any suitable mechanical means may be provided.
lVhen starting a fire, it is preferable to place the valves 28 and 29 in the position shown in dotted lines in Fig. 1. This will give a direct draft for the products of combustion from the fire-pot 6 to the flue 25 through the opening 27 from chamber 3, see the dotted arrows in Fig. 1. When the fire has a sufficient start, the valves 28 and 29 may be moved to the position shown in full lines in Fig. 1, when the path of the gases will be directed through the slots 14 and 15 and through the openings 16 and 17 into the chamber 18 and from thence drawn down through flue-openings 9 into the base flue; the gases circulating through the flue 22, down into the flue-strip 23 and eventually find its way out through the opening 26 into the back-flue 25 The back-flue may have acheck-damper as at 81.
The construction of the fire-pot is such that when the valve 28 is open and the valve 29 is closed the draft is downward in the direction of the opening 26 in the flue 25*. This will prevent the heated gases igniting the coal at the base of the magazine which would otherwise burn and expanding clog the egress of the coal into the fire-pot. The slots 14 and 15 will draw most of the heated gases from the fire-pot and the openings 15 and 16 will turn back all heated gases rising to the top of the fire-pot. The stove is especially constructed to burn soft coal and with the present arrangement it has been found that the coal will burn to a fine ash like hard coal.
7 In Fig. 6 the firepot instead of having slots like 1 1 and 15 in Fig. 1, is provided with a plurality of perforations or open ings 32.
What 1 claim is 1. The combination of a stove casing, a flue having openings communicating with the casing near the top and bot-tom thereof, a fire pot comprising an upper flared portion and a lower frusto-conical portion, the lower part of said frusto-conical portion being perforated and the flared portion provided with a plurality of perforations, and means for closing either one of the flue openings, whereby the products of combustion may be made to pass either upwardly through the fire pot and out through the upper flue opening, or to pass through the perforations in the fire pot and out through the lower flue opening.
2. The combination of a stove casing, a flue having openings communicating with the casing near the top and bottom thereof, a fire pot having a frusto-conical portion and an upper outwardly flared portion, the lower part of said frusto-conical portion having a plurality of elongated slots ar ranged in staggered relation, said outwardly flared portion having a plurality of openings therein, and means for closing either one of the flue openings, whereby the prod nets of combustion may be made to pass either upwardly through the fire pot and out through the upper flue opening, or to pass through the perforations in the fire pot and out through the lower flue opening.
