through the fireplace so that it will be heated and then be discharged at the top part of the fireplace and through a shelf arrangement, with a shield for closing or partly closing the fireplace when desired.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several Views, and in which:

Figure 1 is a front View of the invention, with the shield partly lowered.

Figure 2 is a fragmentary front View with the shield in raised position and the screen in lowered position.

Figure 3 is a vertical sectional view. Figure 4 is a section on line 4-4 of Figure 3. Figure 5 is a section on line 55 of Figure 3. Figure 6 is a section on line 66 of Figure 3. Figure '7 is a section on line 1-4 of Figure 3. Figure 8 is a section on line 8-8 of Figure 4. Figure 9 is a vertical sectional view showing the invention used with an electric heating element and without the chimney.

Figure 10 is a View of the heating element shown in Figure 9.

Figure 11 is a detail view of the shield.

As shown in these drawings, the front A of the device is made in the form of a mantel of ornamental design and preferably formed of sheet metal, with the rear part of the device placed in a regular fireplace provided with a chimney I, as shown in Figures 3 to 8, or this rear part may be placed in an opening formed in a wall, when the device is constructed as shown in Figure 9. An ornamental molding 2 is placed against the wall above theopening to form a top for the device and the shelf 3 has an opening therein closed by a grating 4 which is hingedly connected to the molding, as shown at 5, so that it can be swung upwardly to uncover the opening, when desired.

When the device is used in a fireplace, as in Figures 3 to 8, a casing i3 is placed in the outer casing forming the exterior part of the device and said casing 6 has a bottom part I having an opening therein in which is placed the grate bars 8 provided with depending parts 9 which are connected to a lever I0 having an upwardly extending portion H passing through a slot'IZ in the bottom part I, this part II acting as a handle 5 so that the portion In can be rocked back and forth to rock the grate bars. An ash pan I3 is located below the grate and this pan can be removed by opening an upwardly opening door I4 located at the lower part of the front of the delo vice. The casing 6 has a reduced portion I5 which is connected with the flue I so that the fuel placed on the grate, when ignited, will be subjected to a draft, by opening, or partly opening the door I4 and the products of combustion will pass up 15 the chimney. Of course, if desired, the door I4 can be provided with a damper.

The casing 6 and its reduced upper portion form a passage I6 between its rear part and the rear part of the main casing and the lower end of this passage communicates with the passages I6. These passages I6 are located, one on each side of the ash pit and extend to the opening covered by the door, as shown in Figure 3 and in dotted lines in Figure 5. Thus some of the air entering the door opening will pass through these passages I6 into the passage I6 and pass up the passage 36. This air will be heated by the burning fuel in the casing 6 and then this air will pass upwardly and around the top part of the so casing 6 and then pass through the grating 4 and thus heat the room.

A damper I1 is slidably arranged in' the guideways I8 in the upper part of the main casing and is utilized to control the passage of the products of combustion through the reduced portion i5. The handle I9 of this damper is accessible through an opening covered by an ornamental plug or closure 20 in the front of the main casing.

A spring roller 2I is rotatably supported in the 40 upper part of the main casing and above the top 22 of the casing B and carries a screen 23 which may be pulled down across the front opening 24 of the front A to prevent sparks or the like from flying out into the room. This screen can be held in lowered position in any suitable manner, and by shoving it upwardly, the roller will be rotated by the spring so that the screen will be wound thereon.

A scroll groove 25' is formed in each internal wall of the main casing above the top 22 of the casing 6 for receiving the side edges of a shield 25 which is formed of a plurality of channeled members 2t reversely arranged and having their flanges converging from the bight parts, with the flanges of each member engaging the flanges of adjacent members, as shown in Figure 11. A knob 22! connected to the lower end of the shield so that it can be readily raised and lowered and this shield can be used for entirely closing the opening 24 or for partly closing it or by shoving the shield all the way up, the opening 24 will be fully exposed.

A pair of substantially semi-circular members 28 is located in recesses 29 located, one at each side of the opening, and each member is pivoted in the recess at the middle of its flat side, as shown at 3? so that it can be swung from a position within the recess to a position partly out of the recess or wholly out of the recess. The screen may be attached to these members and then by swinging the members outwardly, the screen will be caused to assume a substantially arcuate formation in front of the opening, with the members 28 forming the sides of the space formed by said arcuate screen. The front edges of these members 28 are formed with the guideways 28' for the shield.

When the device shown in Figures 9 and 10 is to be used, the casing A can be placed in a recess in a wall and an arcuate member 3i supported on a base 32 is placed in the casing with its concaved face facing the opening 24'. The heating elements connected to the concaved face of the member 3| by the binding posts 36 and these elements can be connected to a source of electrical supply in any suitable manner. A backing plate 35 is supported from the rear of the casing in spaced relation and has its front face covered with a layer 36 of asbestos or the like. Thus in this case, the air is heated by electricity and by opening the lower door M, the air will pass therethrough into the lower part of the casing and then flow upwardly through the grating 4' and, of course, some of the heat from the heating elements will be directed through the opening 24 by the member 3|. The door 14 can be held in open or partly open position in any suitable manner. This device is also provided with the shield 25, though it is not necessary to use the screen It is to be understood that changes may be made I in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What is claimed is:-

A fireplace stove comprising a vertically arranged casing having a rear extension of less height than the casing, said extension to be positioned in a fireplace, said casing having a fiat top provided with openings, said casing having a large opening in its front part the lower end of which is spaced from the bottom of the casing, and said casing having a smalleropening in its front part located below the large opening, a door for controlling the smaller opening and having its upper edge hinged to the front of the casing slightly above said lower opening, a closure memher for the large opening, a hollow base member resting on bottom of the casing and hay lg openings in its side walls, said base member being spaced from the rear wall of the extension, a vertically arranged concave-convex member supported by the base member and located in rear of the large opening with its concave side facing said large opening and its rear side slightly spaced from the extension, electric heating members supported on the concave side of said member and a sheet of heat non-conducting material supported by the rear wall of the extension in spaced relation therefrom and located in rear of the concaveconvex member and extending above and below the same.
