' (o1. l26l21) 2 Claims.

This invention relates to fireplace construction, and has more particular reference to a fireplace provided with air heating means.

The primary object of the present invention is to provide a fireplace construction, the front of which is of forwardly curved form in plan, and wherein the air heating device is so constructed and shaped as to provide for its ready adaptation to a fireplace proper whose front is so'curved.

Another object of the present invention is to provide an improved air heating device for use in providing a fireplace construction in which the front of the fireplace proper is of forwardly curved form in plan, said air heating device being of extremely simple and durable construction and providing for eflicient heating of air.

Still another object of the present invention is to provide an air heating device of the above kind having hollow rear and side members whose inner walls are provided with vertical inwardly pressed V-sha'ped ribs connected by relatively wide flat portions, said ribs being adapted for allowing lateral contraction and expansion of said inner walls so as to prevent buckling of the same, as well as to maintain the fire spaced from said walls and allow maximum circulation of air between the same and the fire for preventing excessive overheating of said walls.

Other objects and features of the present invention will become apparent from the following description when considered in connection with the-accompanying drawings, in which: Figure 1 is a front elevational view of a fireplace construction embodying the present invention. v

Figure 2 is a vertical section on: line 2--2 of Figure 1.

Figure 3 is a perspective view of the air heating device forming part of the fireplace construction shown in Figure 1.

Figure 4 is a horizontal section on line 4--4 of Figure 1; and r Figure 5 is a horizontal section on line-5-5 of Figure 2. i

While the present fireplace construction may be built in a straight wall, it has been illustrated as built in the corner of a room at the juncture of two partition walls 5 and 6 separating said room from two adjoining rooms. The fireplace proper includes a rear wall I of suitable form and thickness, side walls 8, a top wall 9, and a front wall III which is of forwardly curved form in plan. This provides the usual fireplace or recess in the lower portion of the fireplace structure,

the front wall l0 having an opening at its lower central portion to provide an open front or entrance II for this recess or fire space. The partial portion Illa of the front wall I0 above this opening II closes the front of the recess or fire space at the top of the latter, and a passage I2, extending upwardly and rearwardly, affords communication between the rear upper portion of the fire space or recessand the lower end of the vertical fiue l3 provided in chimney I4. The lower portion of the rear wall 1 has a vertical front surface I5, while the upper portion of said rear wall has a front surface I6 which slants upwardly and. forwardly. V

Fitted within the fire space or recess of this fireplace proper is an air heating device comprising a unitary metallic structure having a hollow horizontal transverse upper front portion I! which fits within the upper front portion of the fire space or recess directly beneath the topwall 9 and behind the partial portion Illa of the front wall l0, a lower portion which is open at the top,'bottom and front and composed of a hollow rear member I8, and hollow side members I 9. The members I8 and H are closed at the bottom and communicate with each other, the hollow side members I!) communicating at their upper ends with the ends of the hollow upper front portion I! through the upwardly converging upper portion l9a of the side members l9. The back member I8 is closed at the top by means of an upwardly and rearwardly inclined wall 20, and the bottom of the upper front portion I1 is formed by an upwardly and rearwardly inclined wall 2| which is spaced from the wall 20 so as to provide an upwardly and rearwardly inclined throat 22 for the passage of smoke from the top of the fire space to the fiue l3of the chimney. The wall 2| is of forwardly curved form in plan or transversely curved with its side edges joined to the side edges-of the wall 20. The hollow upper front portion I! and the front of the side members [9 are closed by a wall 23 of inverted U-shape whose intermediate portion is forwardly curved to conform to the curvature of the front wall Ill as shown clearly in Figures 3 and 5. Also, the side or leg portions of the wall 23, indicated at 24 are disposed in outwardly and rearwardly diverging relation so that they lie at an angle substantially conforming to the curvature of the front wall ll] of the fireplace proper. Thus, the air heating device lends itself admirably to installation in a fireplace proper whose front is forwardly curved as described. At the same time, the air heating device is of extremely simple and durable construction and provides for efficient heating of air.

Formed in the lower portions of the side members I9 near the fronts of the latter are cold air inlet openings 25, and another cold air inlet 26 1 may be formed in the lower portion of the rear member I 8. Hot air outlet openings 21 are formed in the upper portions of the side members I9, while a further hot air outlet opening 28 is provided in the top Wall of the upper front portion 11. The front edge of this opening 28 is preferably curved concentric with the curvature of the front wall 23, and a hot air outlet passage 29 may be formed vertically in the topwall 9 of the fireplace proper to receive a grill 30 of similar shape where the passage 29 opens through the top of wall 9. As the top of wall 9 is horizontal and fiat, it forms an admirable shelf or mantlepiece curving about the curved wall of chimney I4. The cold air inlet openings '25 may communicate with passages 3| extending through the front wall In of the fireplace proper at opposite sides of the opening II, as well as through low-built extensions 32 provided at opposite sides of the fireplace opening II upon a hearth 33a which extends in front of the fireplace proper at the bottom of the same. The passages 3| preferably open through the extensions- 32 where they are provided with suitable grills 33, and the tops of the extensions 32 are preferably fiat so as to provide suitable stands for fiowers or ornaments. Other passages 34 may be provided in the back wall 6 and the partitions and 6 for conducting cold air from the adjoining rooms to the cold air inlet 26, and the hot air outlet 21 may communicate with further passages 35 provided through the side walls 8 of the fireplace proper and the partitions 5 and 6 for conducting hot air into the adjoining rooms from the heating device installed in the room separated from such adjoining rooms by the partitions 5 and 6. It will of course be understood, however, that in some installations, the

openings

26 and 21 need not be utilized, in which case the

passages

34 and 35 need not be provided. When the latter passages are provided, they are provided at their inlet and outlet ends respectively, with the

grills

36 and 31.

The'inner walls of the hollow rear member I31;-

and the side members I9 are provided with a series of spaced vertical ribs 38 which are of V-shape in cross section and pressed inwardly as shown clearly in the several views. These and contraction of the inner walls of said members I8 and I9 so that buckling of the same is effectively prevented. In addition, these ribs are connected by relatively Wide fiat portions and maintain most of the fire in spaced relation to end of throat 22 for controlling the draft from the fire space to the chimney, which damper ribs provide for lateral or horizontal expansion 5 "proper.

has suitable operating means, such as a lever 40.

It will of course be understood that a suitable fire is built within the lower portion of the air heating device, and cold air entering the heater through the

openings

25 and 26 will be effectively heated in fiowing to the

outlet openings

21 and 28. This heated air will be discharged into the rooms and effective heating of the rooms thereby will be had. It will be seen that I have provided a very efficient air heating fireplace of attractive form and design, and it will be apparent that minor changes may be made in specific details of the invention illustrated and described, without departing from the spirit and scope of the invention as claimed.
