2 Claims.

Our invention relates to fireplace heaters and has as one of its objects the provision of-a sheet metal heater to be installed in the upper portion of a fireplace and arranged to circulate heat back into the room instead of wasting the same through the chimney.

A further object of the invention is to provide a heater of this character which can be quickly installed or removed from the fireplace and is highly efficient in use.

Another object of the invention is to provide a device of this character which not only effectively heats the interior of the room but precludes the passage of smoke intothe room.

With the preceding and other objects and advantages in mind the invention consists in the novel combination of elements and constructions and arrangement of parts in operation to be hereinafter specifically referred to, and illustrated in the accompanying drawings whereln,-.

Figure 1 is a fragmentary sectional view of a fireplace mantelhaving my invention associated therewith, the'invention being shown partly in section and partly in eleva-tion;

Figure 2 is a front elevation of the invention moved from the mantel and having parts broken away;

Figure 3 is a vertical sectional view taken on the line 3 3 of Figure 1, and,

Figure 4 is a similar View taken on line 4 4 of Figure 3.

Referring to the invention in detail a conventional fireplace is indicated at 5, and is provided with the usual mantel 6 and chimney 7.

Arranged in the mantel at a point to receive the heatv and products of combustion from the hearth, not shown, is a substantially rectangular hood 10 which, as shown inFgure 1, is open at the bottom.` The upper wall of the hood -is formed with a. plurality of relatively large openings 11 andleading from each of these openings is a, horizontally arranged flue 12.V These flues 12 Vare formed with lateral flanges 12a which are riveted or otherwise secured to the top and side walls of the hood, as shown in Figure 4. Y

A smoke chamber 13 is also arranged in the mantel at a point slightly above the hood 10 and in vertical alinement with the chimney 7.

The smoke chamber is also formed of sheet metal and is substantially rectangular in configuration. Arising from the upper wall of the smoke chamber at a central point is a. rectangular-incross-section-ue or voutlet 14 which extends Serial No. 558,150

from opposite sides, as indicated at 15, and is provided with a plurality of outlet openings 16.

Formed in the front wall of the smoke chamber slightly above the bottom thereof is a plurality of spaced rectangular openings 17, each of which is arranged in alinement with the forward end @5f of one of the fiues 12. These fiues are provided with lateral flanges 18, which are detachably secured to the front wall of the smoke chamber by fasteners 19.

For the purpose of controlling the passage of n the products of combustion, the damper is arranged in the flue 14 and is fixed to a rock shaft 21, which is journalled in side wall of the flue. One end of the rock shaft is provided with a handle 22 which, in practice, will extend from 75 one side of the fireplace.

In order to cause a circulation of air in the mantel, an inlet grate 23 is arranged in the front wall of the mantel, While an outlet grate 24 is arranged in the top Wall of the mantel. Thus,

air circulating through the mantel will be heated by contactingwith the hood 10 and iiues 12. It, therefore, follows that a constant flow of warm air will be conducted from the mantel into the v room adjoining the same.

Manifestly, it is within the spirit and scope of the invention as claimed to locate the grate 23 inthe side wall instead of the front wall while the outlet grate 24 may be located above the grate 23 in the front or side wall of the mane tel and need not necessarily be in the top Wall as shown.- It vwill also be manifest that it will be impossible for smoke to enter the room as the same is conducted into the smoke chamber by way of hood 10 and conduit 12.

In addition to the lheater efficiently heating the room it will be observed that there are no protruding parts. In other words, the entire device is enclosed within the mantel and chimney of the fireplace.

What is claimed is:

l. An integral heater unit for mounting within an open fire-place, characterized by a hood to be positioned above the hearth of the fire-place,

a plurality of spaced flues having their forward ends connected to the hood, a combined smoke chamber and chimney outlet attached to the opposed ends of the flues, the floor of the chamber being below the level of the flues, whereby when the unit is operatively mounted within the fireand a smoke chamber communicating with the chimney, a plurality of flues connecting the hood with the smoke chamber, the hood, flues and smoke chamber being arranged within the con- Ynes of the heating chamber, and air inlet and outlet means for said hollow mantel.
