BASE-BURNING- FIRE PLAGE HEATER.

' The schedule referred to in these Letters Patent and making part of the same scending dranght has been at the-back or sides of the fire-pot, and generallyby a pipe outside the casing, forming the combustion-chamber. Y

My invention is made for equalizing the heat, and

preventingany'portion or the state or heater becoming ton highly heated,and alsofor insuring the necessary temperaturein the front portion of the stove, for heating the hasement or room in" which the fireplace heater is located. l

I make nse ot' a. double casing in the front part of the stove, below the top of ,the fire-pot,.said casing ibrniinga-descendi ng fluefthat opehs at-top into the combustion-chainher, andat the liottoin 'into'flnes-at the base of the heater. By this construction the prodnctsof combustion are directed toward the front of the heater, therebylessening the intensity of the heat at the confined rear portion of the combustion-chamher, and then the products of combustion pass up the tide or flues at the rear, and the heated atmosphere 7 also ascends to the rooms abovethrongh air-pipes, as

now usual.

In the drawing Figure 1 is a vertical section at the line x x of fig.

Figure 2 is a seotionalplan at the line 3 y of fig. 1;

Figure 3 is a vertica-l section at the line z z. The base of the stove is made of the bottom plate a, above which are platesforming side-fines, b b, and

the fire-pot g and casing f, and over the casing f is a top plate, h, with an opening, 0', for fuel to be intro:

duced into the magazine or hopper The firerpot g and casing-f coincide at the back part of the heater, but the casing is shaped as in fig. 2, so that there will be a segmental annular space, l, between the fire-pot and casing, and this is covered at -the top by a similarly shaped plate, a.- At the level,

or nearly so, of the top of the fire-pot, and in this plate 1:,are openings toward the front part. I prefer to have a number of holes, as seen in fig. 2.

This space I forms a descending flue, that opens into theflues 1) l), by means of holes 0 0, through the plate 0.

It will now be understood that the fire burns at the base of the magazine It, and the products of combustion ascend intothe chamber a, between the magazine It and casingf, and descend, through the fluel, to the does I: b and c, and thence pass to the chimney-flue v.

A damper, at 8, allows, when open, a direct draught to the flue 11 in kindling the fire, and a damper, t, at the base of the fine 42, admitsairfrom the ash-box or pit to lesseuth'e strength of the draught when thefire is burning too' strongly.

A slide or cover at r facilitates the cleaning of the back fine from earthy accumulations.

I claim as my iuvention- 1. The descending flue 1, between the fire-pot g and front portion of the casing 1, opening at the top into the combustion-chamber u, and at the bottom into the side fln'es b b of the fire-place heater, substantially as =Witnesses:
