IMPROVEMENT IN FURNACES AND HEATERS.

Specification forming part of Letters Patent N0.15S,l60, dated January 5, 1875; application filed October 26, 1874. a i

To all whom itmay concern:

Be it known that we, FELIX BLAZICEK and GEORG WILHELM MoRIrz BAUER, of the city of Vienna, Austria, have invented an Improved Furnace or Heater, of which the following is a specification:

Our invention consists of a fire-pot for heat ers or furnaces, which we will now proceed to describe, and which is shown in the accompanying drawing, in which- Figure 1 is a vertical section of the stove or furnace; Fig. 2, a sectional plan on the line 1 2, Fig. 1; and Fig. 3, a sectional plan on the line 3 4,-Fig. 1.

A is the lower casing of the furnace, inclosing the ash -chamber a, and having an opening through which access can be had to the said chamber, and which is provided with a suitable hinged door, a. 'D is the outer casing of the combustion-chamber, and is fitted to the top of the lower casing, A. A series of bars, E, surround the combustion-chamber proper, which communicates with the outlet (1 to the chimney, these grate-bars being wider at the bottom than at the top, thus imparting a flaring form to the said chamber. The bars rest upon the lower casing, A, and their outer edges are in contact with the casing D, and in the spaces between the grate-bars are arranged at intervals deflectors f, which serve to direct the air toward the interior of the combustion chamber. A grate, F, having a handle, g, is arranged at the lower end of the combustion-chamber, and is so supported upon projections h of the lower casing as to be readily removable from its position. A detachable cap, H, closes the top of the furnace, through which fuel is introduced to the com- 7 bustion-chainber.

The operation of the furnace is as follows: The combustion-chamber having been filled with fuel, the fire is lighted at the top, and the air, entering the spaces between the vertical bars at the base of the same, passes up between them and out into the mass of fuel to sustain this combustion, the draft increasing as the fire is developed in the upper layers of fuel. The air in its upward passage becomes heated, and on mixing with the gases from the burning fuel produces an intense heat. The ignited fuel at the top of the furnace, acting on the fuel beneath, causes a distillation of the same, and the evolved gases, mixing with the air which enters between the grate-bars, are thoroughly consumed in passing through the incandescent fuelabove.

When all the fuel in the combustion-chamber has been exhausted, the grate lb is withdrawn through the opening of the lower casing, the ashes falling onto the bottom of the latter, from which they can be readily removed.

Our invention is not only applicable to heating-stoves, but may be used to advantage in connection with steam-boilers, and with other furnaces.

We claim as our invention 1. The combination, in a fire-box, of a casing, D, and a series of vertical plates or bars, E, arranged with their rear edges in contact with the said casing, to form intermediate airchannels, communicating at their lower ends with an air passage or chamber, all as and for the purpose set forth.

2. The combination, with the bars E, ar-

ranged within the casing D, of air-deflecting ribs f between the bars, as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
