Application filed February 26, 1923. Serial No. 621,133.
To all whom it may concern:
Be it known that I, HARRY A. ELSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a certain new and. useful Improvement in Fireplaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
This invention relates to fireplaces such as are used in dwelling houses for providing heat. 7 i
The general object of the invention is to provide a fireplace which is so constructed that the heat from the material burned serves, in an eflicient manner, to heat cold air which is conveyed to the rooms to be heated. One of the specific objects of the invention is to provide a fireplace having an inlet for cold air in the lower part of the front portion and an outlet for heated air near the top of the front together with means whereby the air going in at the bottom and out at the top is heated with a maximum of efficiency.
Another object of the invention isto provide a fireplace with means to lead cold air ,therethrough, together Withmeans whereby the desired humidity of the air is maintained and wherein the products of, combustion serve to heat water in a water tank.
A further object of my invention is to provide a fireplace of the kind wherein cold air, is warmed and returned to the room, with a casing so that the fireplace may be set up in a room as acomplete unit without the need for assembling after it reaches the place of installation. v
Other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings, wherein Fig. 1 is a perspective view showing an embodiment of my invention; ,Fig. 2 is a central section through a fireplaceand Fig. 3 is a front elevation of a fireplace.
Referring to the drawings by reference characters, I have shown at a fireplace. This fireplace may comprise the usual brick work 11 whichsurrounds .a heating member embodying the features of myinvention.
:This heating member comprises a fire chamber wherein the source of heat is arranged. The heat may be derived from a hydro-carbon burner or means for burning coal or wood. A tortuous assage leads from the fire chamber to a cli arrangement is such that the air which is used to heat the room is drawn through the fireplace without coming into contact with the hot gases, and is then led into the room to be warmed. V o
By referring to Figs. 1 and 2, wherein the detailsof one embodiment of my invention are shown, I show a fire chamber 15 having a source of heat 16 therein. chamber is defined by a lower, upwardly directed wall 17, by a rear wall 18 which may be vertical, and by an upwardly inclined wall 19.
The hot gases from the fire pass along the inclined plate 19 and impinge against a plate 20, shown as inclined toward the rear of the fireplace. The walls 19 and 20 are joined respectively to walls 21 and 22 which are here shown as arranged in parallel manner. Thewall 21 has a tight engagement against the back wall 24 of the fireplace, while the wall 22 is shown as connected; to another inclined wall 23, the latter of which is inclined toward the front of the fireplace, and which in turn merges into a portion 25 shown as vertical.
It will be noted that the wall 23 overhangs the wall 22 for a purpose to be presently described. 1
I show a baflle member 28 indicated as secured to the back wall 24 and having a portion thereof deflected toward the ,plate 23.
The horizontal portions 21 and 22 are shown as connected by the plurality of open ended tubular members 30. These tubular members, as will be seen inFig. 1, are arranged in staggered relation with each other, and the heated gases from the source of heat pass between and around these tubular members.
The air to be warmed, which may be taken into the fireplace through openings (see Fig. 3) adjacent the bottom thereof, passes within the fireplace, around the sides and along the bottom of the fire chamber 15 and then into contact with the plate 19. In order to insure most of the air coming in contact with this plate, I provide a baflie 36 shown as engaging the rear of the fireplace and the plate 21. The air, after being warmed by the plate 19, passes through the imney. The
The
her in the rear of the fire chamber.
A. receptacle for water is shown adjacent the fireplace as at 41. This receptacle is in the path of the hot air which goes forth from l'he fireplace so that the water contained therein serves to moisten the air supplied to the room.
The warm air may be led to the room through openings 44 in the front of the fireplace near the top portion thereof.
- 'Ihe'fireplace proper, embodying my invention, may be built into a brick fireplace which is shown in Fig.
In order to cause the cold air to pass around the fire chamber, I provide baffle members 52 shown as arranged adjacent the sides of the fireplace. These baffle members engage the fireplace along one edge and engage the framework for the fireplace along the other edge.
In order that the air for supporting combustion in the heater 16 may not be all supplied from the room being heated, I may provide a cold air duct 70, which leads to the atmosphere. This cold air duct may be provided with a valve mechanism so that the amount of fresh air supplied can be regulated.
It is also frequently desirable to provide meanswhereby fresh air, taken from a point outside the room being heated, may be led through the fireplace. Means for doing this is shown at 71, where the fresh air duct is indicated as communicating with the cham- The passage of air through this duct 71 may be controlled, if desired, by a closure 7:2 which may be operated in any suitable manner from the front of the fireplace.
'From the foregoing description, it will be apparent that I have provided a novel form of fireplace which can be economically manufaetured, readily installed, and which is highly efficient in use.
Having thus described my invention, I claim:
1. A fireplace structure having a fire chamber, and a front brick wall, a fine at the top of the fire chamber and extended through said fireplace structure, an air passageway adjacent to said fire chamber and having a fresh air inlet, said air passageway increasing in area from the inlet thereto, pipes extending across said flue, an air passageway and expansion chamber directly -above said pipes, said pipes communi 'ating with said fresh air inlet. said front wall having openings therein through which the hot air discharges, the top of said fire chamber being inclined toward the front of the fireplace, said inclined part being made of sheet metal whereby it may be heated to thus heat the air passing over the other side thereof.
2.
