BradfordRymer, Cleveland, Tenn assignor to Dixie Foundry Company, Inc., Cleveland, Tenn., a corporation of Delaware Application January 2'7, 1945, Serial No. 574,897 1 Claim. (01. 126-190) This invention relates to stoves adapted for burning hard fuel and has particular reference to a novel and efiicient manner of introducing fuel into the combustion chamber in such a Way as to eliminate substantially the escape'of smoke and fumes from the combustion chamber into the space in which the stove-is arranged at such time.

A principal object of the invention, therefore,

is to provide in a stove adapted for burning hard fuel a means for introducing fuel into the combustion chamber in such a manner so as to substantially prevent the escape of fumes and smoke from the combustion chamber through the fuel feed door opening.

Other and further objects of the invention will be apparent from the following description and claim and will be understood by reference to the accompanying drawings, of which there are two sheets, which, by way of illustration, show a preferred embodiment and the principles thereof and what I now consider to be the best mode in which I have contemplated applying those principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claim.

In the drawings:

Fig. 1 is a front elevational view of a stove embodying my invention;

Fig. 2 is a fragmentary sectional view taken in a plane along the line 2-2 of Fig. 1, looking in the direction of the arrows;

Fig. 3 is a view similar to Fig. 2 but with the fuel feed door in open position;

Fig. 4 is a view similar to Fig. 3 but showing the position of the fuel feed door and closure during closing movement; and

Fig. 5 is a fragmentary horizontal sectional view taken in a plane along the line 55 of Fig. 3, looking in the direction ofv the arrows.

In Fig. 1 a stove embodying my invention is illustrated. This comprises a stove adapted for burning hard fuel and includes an opening l0 adjacent the upper end thereof and a pivoted door I 2 provided with an operating handle [4. The door 12 may be made of any suitable construction and is hinged for movement between the position illustrated in Fig. 2 and that illustrated in Fig. 3 on a pivot IS. The opening in comprises aligned openings in the outer and inner panels 18 and 20 of the stove body or cabinet. Each side of the door I2 is provided with an movement of the door l2.

inwardly extending flange 22, each of which is provided'with a laterally extending lug 24 which cooperateswith the edge of the opening H3 in the panel 20 for'li miting the outward opening I The door I2 at its top and sides is provided with an inwardly extending flange 26 which abuts the outer surface of the wall 20 around the opening [0 when the door is closed so as to effectively seal the opening it! through the panel or wall 20.

A closure member'28 in the form of a receptacle presented toward the opening I0 is hinged inside the stove on the pivot 30 for movement a between the positions illustrated in Figs. 3 and 4;

This member 28 includes spaced walls 32 connected by curved wall 34; The member 28 thus is open toward the opening it] as well as downwardly. This member 28 is pivoted in the upper part of the combustion chamber 36.

The front and bottom edges 38 and 40 of the walls 32 cooperate with flanges 42 and 44 and the free edge 46 of the member 28 cooperates with the flange or chute 48 to form a closure for the opening l0 interiorly of the combustion chamber 36. The flanges 44 and 48 form a chute which extends inwardly and downwardly from the opening l0 and the panel 20 and cooperates with the member 28 when arranged as illustrated in Fig. 3 to prevent the escape of smoke and fumes from the combustion chamber 36 through the opening in when the door I2 is open.

Each of the side walls 32 of the member 28 is provided with a pivoted dog 50 in the form of a bellcrank pivoted at 52. With the door l2 in its closed position, as illustrated in Fig. 2, the lugs 24 on the sides 22 of the door l2 are positioned below the dogs 50 and during opening movement of the door the dogs are free to swing in a counterclockwise direction about their pivot 52, thereb permitting free opening movement of the door without any corresponding movement of the closure 28.

When the door arrives at its open position, as illustrated in Fig. 3, the lugs 24 will have moved to such an extent so as to permit the dogs 50 to assume the position illustrated in Fig. 3. In this position an ear 54 of each of the dogs cooperates with a lug 24- so as to maintain the dog 50 in the position.

Upon closing movement of the door, the lugs 24 reacting on the ends of the dogs 50 in the manner as illustrated in Fig. 4, will cause the closure 28 to swing in a clockwise direction so as to permit the lu s 24 to clear the ends of the do s 50 and return to their position as illustrated in Fig. 2.

The other ends of the dogs are formed to engage the wall 34 so as to limit their clockwise rotation.

As soon as each of the lugs 24 has moved through an arc sufficient to clear the end of the dog against which it is bearing, as illustrated in Fig. 4, the closure member 28 will swing back to its position as illustrated in Fig. 2, the mass of.

the closure 28 and its side walls and the center of gravity "being-so related to the pivot 30 that the closure 28 normally assumes the position illustrated in Figs. 2 and 3.

It will thus be observed that when the door [2 position thereof for closing said opening, a chute projecting inwardly from said opening, said clois opened, the closure 28 prevents the escape of smoke and fumes from the combustion chamber into the room. When the door 12 is open, the door [2, chute 48, and closure member '28 form a hopper adaptedto receive fuel. During the closing movement of the door l2, as illustrated in Fig;

4, the fuel in the hopper provided by the door l2,

the chute 48 and the closure 28 will be automatsure in its open position cooperating with said chute so as to accommodate a charge of fuel, a movable inner closure pivoted to said stove adilacent said opening and cooperable with said "chute for automaticall closing said opening on V the inside thereof, said outer closure having lugs ically discharged into the combustionachamber 36 through the ap created. .bythe inward movement of the closure member 28. I While theicom- 'bustion chamber 3.6. is open to the room, atthis time, the time interval is very small and the fuel feeding into the. combustion chamber 35. from theh0pper,. as. previously described, will tend to,

eliminate any flow of smoke. or fumes from the combustion chamberBB into the room.

Theinside of the outer door or closure 12 is on thexinner side thereof, dogs pivoted to said inner closure and arranged at the sides thereof and in the path of movement of said lugs during movement of said outer closure from open to closed position whereby upon closing movement of said outer closure said lugs will engage said dogs and thereby move said inner closure to its open position, said closures and the lugs and dogs carried thereby being constructed and arranged so that after theinner closur-ehas been opened said lugs will disengage themselves from said dogs whereby to permit said inner. closure to close and bevcloseol when said'outer closure has completed its closing movement, the pivotal connection of said dogs on said inner closure permitting said lugs to temporarily displace said dogs upon opening movement of said outer closure without a corresponding movement of said inner closure.
