AIR-WARMING FURNACE.

SPECIFICATION forming part of Letters Patent No. 511,164, dated December 19, 1893.

Application filed July 7, 1893. Serial No. 479,847. (No model.) 7

To a whom it may concern.-

Be it knownthat we, JOSEPH SOHILL, JOHN SGHILL, and PETER SoHILL, citizens of the United States, and residents of the city of Crestline, in the county of Crawford, in the State of Ohio, have invented a new and useful Air-Warming Furnace, of which the following is a correct description.

The invention relates to certain improvements in that class of heaters or hot-air furnaces designed for use in dwelling houses and other structures, in which the heater or furnace proper is inclosed, except in its front central portion, by a casing which forms in connection therewith, an air chamber, which receives currents of fresh air at or nearitslower extremity and which discharges the same warmed to the desired degree, through suitable openings in the upper extremity of the air casing, into metallic conduits, through which they are conveyed to the various portions of the structure which are to be warmed.

A leading object of the construction which we have devised, and which will now be described,is to provide at small expense a novel series or system of fines, for the discharge of the products of combustion; and a novel means for assembling the same ll} connection with a combustionchamber, of steel, in which necessity for perforating thebody of the com bustion chamber in the act of securing the parts together is avoided, and whereby the circulation is sufiiciently restricted and controlled without theaid of a damper.

Another object is the provision of means for presenting to the action of the incoming and ascending air currents, an extensive radiating surface, or series of surfaces, in the interval between thebody of the combustion chamber and the bodyof the air casing, in

connection with the supports of such parts. The invention consistsin the novel parts, or combinations of parts which will now be described in detail, and which will be specifically set forth in the paragraphs which follow such detailed description.

In the accompanying drawings which constitute a part of this specification,Figure 1 represents a top plan view of the combustion and air-warming chamber section of the fur; face. Fig. 2 is a vertical longitudinal central seotion,as in the line :r--:c of Fig. 1. Fig. 3

is an irregular horizontal section,as in the line y-y of Fig. 2. Fig. l is a transverse central section,as in the line c-.e of Fig. 3. Fig. 5 is a rear elevation, and Fig. 6 is a central section, of the auxiliary or intermediate flue plate, detached.

It will be seen that the base-plate or lower head a, of the combustion and air chamber section a, is composed of an inner ring 03, an outer ring a and intermediate connecting arms a, which serve as bearings for the lower extremity of the detachable radiating plates of; and that at suitable intervals the inner ring has perforations 13 to receive securing rods 19, by which when the parts are in place, the upper and lower plates are secured together. The upper head Z) is similar in its general construction to the lower head but the ring 5 connects the exterior arms 17 not to an interior ring, but to a closed head or dome bfiwhich constitutes the top of the combustion chamber. Atthefront'thefeedchute f, is secured by its flanges f to the body of the inner cylinder or combustion chamber 0, in an ordinary manner.

In the rear of the extremityof the combustion chamber 0, is the smoke hood 3, which is of the T-form shown, the open ended arms 3 of the same extending as shown nearly to the body of the cylinder.

Upon the exterior of the cylinder c,coincident with the smoke opening is fitted the intermediate plate ip, which has raised rim or flange to constitute a recessed surface, within which is received by its flange (1 the diving and out-take fine (I, the lower and discharging end d of which projects outwardly through the opening'in the body of the air casing cc. Y

The rear opening in thebody of the cylinder 0, is of dimensions su fficiently greater than the corresponding portions of the smoke hood, the diving and out-take fine and the intermediate plate, to permit the flanges of the hood, the diving fine, and the interposed plate to be suitably secured together, without the necessity for perforating the body of the combustion chamber itself; thereby effecting much economy of time and labor.

The radiating plates a having been set in place within their bearings, the air casing etc, is byits rear opening, fitted over the project- I ing extremity of the discharging end 61 ,01 the out-take flue, and its front is fitted over the I body of the feed=chute. This heing done, the

securing rods are'fixed in place, either'by' heading down, orrby the application of suitable nuts.

The provision of the T-arms, upon the retarding-hood and the location of the same at a point near the Walls, and near the upper extremity of the combustion-chamber, prevent a rapidescape of the products of combustion;

and retard the flowof the smoke currents to.

such an extent that the provision of a damper to efiect this purpose is rendered unnecessary. The nature and objects of the invention having been thus described, and the construction and operation of the apparatus in which it is embodied having'bee'u set torth,what is claimed is- 1. The cylindrical combustion-chamber c; the cylindrical air-casing ac; the base-plate as, having inner ring a outer ring u connecting and supporting arms a and perforations 132; the upper head I), having central dome b exterior-ring b and the connecting-arms b the detachable plate aipand the secur ing rods 19; in combination; substantially as specified.

2. In an air-warming furnace, the combination with the combustion-chamber, of the described smoke-retarding hood and flue, having the inlet branches 3 arranged in theu'pper, rear portions ofsuch chamber, as shown, and the damperle ss diving and out-take flue, between the combustion-chamber and the aircasing and-leading directly downward from tially as and for the purposes set forth.

" 3. In an air-warming furnace, the combination Withthe combustion-chambemof the flanged T-shape'd smoke-retarding hood and the smoke-retarding hood and flue; 'substanflue therein; the flanged diving and out-take fine, in the encircling air-chamber of the fur pace; and the recessed or flangedintermeflange of the T-shaped smoke-hood, and flue; I

substantially as set forth.
