Application filed April To all whom, it may concern:
Be it known that I, EDMOND BENN Wirr- SON, Sr., a citizen of the United States, and a resident of Bentonville, in the county of Benton and State of Arkansas, have invented a new and useful Improvement in Stoves, of which the following is a full, clear, and exact description.
The purpose of the invention is to improve upon the construction of what is known as air-tight stoves for burning either wood or coal, and to provide means whereby atmospheric air will be admitted to a trunk located beneath the grate and delivered thereby to each side of a chest pi'eferably at the front and within the stove, which air is received from asuitable valved draft box at the opposite side of the stove in communication with the interior thereof and with the atmosphere.
A 'further purpose of the invention is to provide a chest with an upwardly-extending crooked or Siphon-shaped hot air pipe, preferably adjustably mounted and designed to deliver heated air to the upper surface of the bed of the fire, and also to provide the chest with a discharge opening beneath the grate, which discharge or outlet opening is controlled by an exteriorly operated damper, whereby hot air with more or less of a normally strong draft is simultaneously delivered beneath and above a gi'ate, or above a grate only when a slow 'fire is needed.
Another purpose of the invention is to so locate the upper outlet of the chest relatively to its inlets and under outlet that a roper distribution of the hot air therefrom will not be interfered with, and likewise to connect the chest with an exteriorly operated air pump to provide a strong forced draft when required, or to assist the natural draft when necessary.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure l is a vertical section through a stove, illustrating the grate bar and the applied attachment in side elevation; Fig. 2 is an enlarged vertical section through the lower portion of the stove and the attach- Specification of Let 16,1906. Serial No. 311,896.

ment; Fig. 3 is a detail plan view of the air trunk and its connecting draft box and chest, the view being drawn upon an enlarged scale, F ig. 4t is an enlarged horizontal section through the air trunk and its connected draft box and chest shown in Fig. 3; and Fig. 5 is a vertical transverse section through the inner end portion of the chest, the section being taken substantially on the line 5-5 of Fig. 3.
A represents the body of a stove, which is of air-tight construction or practically so; and the said body A is in communication with an ash pit A', the latter being also as air-tight as possible. The grate A is located in the fire pot A1, constructed to burn wood onlyJ or coal only, or both wood and coal, since the attachment is adaptable to any type of stove.
ln the drawings the grate A3 is shown adapted `for coal and has a dumping grate having opposing trunnions 11 suitably mounted in opposing sides of the 'lire pot A1, and the forward portion of the grate A3 when in its normal or receiving position rests upon a semi-circular Yflange l2 formed on the wall of the 'lire pot or attached thereto, so that the rear portion of the grate A is that which dumps to spill the ashes into the ash pit A. ln the further construction of the grate A3 it is provided with a large opening or out away section 13 at its forward central section.
Below the grate A, preferably at the rear of thc body A a draft box B is fitted in the body, extending partially within and partially without the same, as is shown best in Fig. 2, and the outer end of the draft box B is provided with a slide 14 for the admission of air. Y
A chest B is located opposite the draft box B at the 'forward portion of the stove, both the dra ft box and chest being below the grate; and said draft box and chest are both an annular flange 15 extending around the body at the opening which establishes communication between it and the ash pit, as shown in Figs. 1 and 2. The draft box B and opposing chest B/ are included in a circular trunk B2, best shown in Figs. 3 and 4. The trunk B`l may be integral with the draft box B and the chest B', or the said trunk may be made in sections and the ends of the sections introduced into the draft box and chest; but the trunk B2 tapers as it approaches the chest B,being of greatest diameter where it connects with and said grate A3 may be IIO the draft box B, so that a maximum amount of air is received into the trunk B2 through the draft box B, and the draft is accelerated by the tapering of the trunk as it approaches the chest B', furthermore, the air in conse- I quence enters the chest B with greater force than if the trunk were of uniform diameter.
The inner end of the chest B is open and extends a desired distance in the direction of the center of the grate A3, so as to direct the air as much as possible to the lower central portion of the grate, so that said air may distribute itself equally under all portions of the grate. In addition to the end outlet 16 the chest B is provided with an outlet opening 17 in its upper portion to the rear of the connection of the trunk B2 with said chest B, as is illustrated in Fig. 2. A collar'lS is Inade to surround this outlet 17 and extends upward from the chest, being provided near its upper end with a pin 19, the said pin being adapted to enter an interiorly threaded portion of the enlarged lower end 2O of a hot air pipe D, whose upper end 21 is curved downward in direction of the center of the grate A3 as is illustrated in Fig. 2. It will thus be observed that the hot air pipe D can be readily turned upon its support. In some instances it is desirable that said hot air pi e be located as close as possible to the wall 1 of the fire pot A4, and yet admit of the turning of the pipe.
A damper 22 is provided for the end outlet portion 16 of the chest B and at its free end enters a slot 22'L in the said chest, while the opposite end portion of the damper is secured to a rod 23 pivoted in an offset or lug 24 from one side of the body, and the handle end of the rod 23 is carried out through the forward portion of the body as shown in Figs. 1 and 3, so that as is illustrated in Fig. 5 the said damper may be raised or lowered to to close the outlet 16 of the chest as tice may be found necessary.
A force pump C is located Within the body of the stove. This force pump C is provided with a tapering lower delivery section 26, which is inclined downward in the direction of the central portion of the grate A3, and the lower orcontracted end of the delivery end 26 of said force pump C is made to enter the upper portion of the chest B between the outer end thereof and the upper outlet 17 and the inclination of the nozzle or delivery section 26 of said force pump C is such as to direct the air forced from the body .of the said pump diagonally out through the forcibly remove pipe D, so as to kindle up a comparatively dead fire, or to enliven a fire at short notice. l
The pump C is provided with a plunger l pump.
ering air above and below 27 made of asbestos or the like `sofas'not to be affected by heat, the pump being entirely within the body of the stove and the plunger or piston rod 28 extends up and out through the top of the stove, and is provided with a handle 29 to facilitate the operation of the The stove is filled at the top through an opening normally closed by a removable cover 30; and the fuel is shot down upon the grate preferably by means of a chute 31.
desire it to be understood that if desired the pump can be placed outside of the iire pot,` that is, between the fire brick and the side of the stove, or between the -hre pot and the wall of the stove.
Thus it will be observed that the air which may be delivered both at the top and the bottom of the grate is delivered thereto in a highly heated state, thus materially promoting combustion and greatly facilitating the draft; and if a slow fire is desired, the damper 22 is closed, or partially closed, so as to cut off the supply of cold air to the bottom of the grate while the heated air is delivered continuously to the bed of fuel on the grate, and the pipe 21 can be turned so as to direct more or less of the hot air to the side of the stove and thus keep the fire still lower for a period of time. operated and controlled in the same manner as is customary with other slides of its type.
By means of the construction above mentioned all the particles of fuel are consumed that it is possible to consume iri a stove, and therefore the greatest amount of heat is obtained, and the fire can be regulated so as toA have a fierce or a slow fire at will, and furthermore an exceedingly fierce fire may be quickly and conveniently built up even thoughthe fire over the grate is quite low.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent,`
