LIGHTING AND HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 485,827, dated November 8, 1892.

Application filed August 14, 1889- Renewed April 30, 1892- Serial No. 431,365- (No model.)

To all whom it may concern.-

Be it known that I, DANIEL WEBSTER CLEGG, of Stapleton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Lighting and Heating Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a simple, cheap, and effective apparatus whereby culinary and other operations requiring heat may be performed without necessarily using the light accompanying the flame from which the heat is derived. Said invention comprises certain novel combinations of parts whereby said objects are effectually secured.

Figure 1 is a side elevation and partial sectional view illustrating the said invention. Fig. 2 is a horizontal sectional view taken in the line a: m of Fig. 1.

A represents a chimney, which may be that of an ordinary kerosene-lamp with any suitable burner. When it is desired to utilize the light from the latter, this chimney should be of glass. When it is not specially desired to utilize the light aforesaid, said chimney may be of metal or other opaque material. In practice it is preferred to'employ a kerosene-lamp having any suitable burner.

The part shown at B in the drawings indicates the oil-reservoir of a kerosene-lamp, of which a is the circumferential rim or burner, the chimney A being supported thereon in the usual or any suitable manner.

0 indicates the cone of a burner; but an Argand or any other suitable kind of burner may be employed.

F is a shell made, preferably, of metal and conforming in its general outline to the adjacent portion of the chimney A, with a space 1) between it and the chimney. Any desired number of holes or orifices c are formed in said shell.

(1 cl are annular plates, the central openings of which correspond in shape and size with the adjacent portion of the chimney A, so that the said chimney, being thrust into said openings, the shell F is supported thereon, as shown in the drawings. In theannular plates (Z cl are any desired number of holes or orifices a. ble of attachment to a chimney A, as just described, is when so attached the means whereby the other operative parts of the apparatus are supported, as hereinafter presently explained.

G is a shade intended to be capable of serving the double purpose of an ordinary lamp shade and of a deflector, by which external atmospheric air may be gathered and de flected upward to the opening I) at the top of said shade. This shade is attached to or carriedby the shell F, as hereinafter described. Placed upon or attached to the shade Gr is a cylinder H, which issubstantially concentric with the shell F, and consequently with the upper part of the chimney A. Said cylinder being of greater diameter than the shell F, provides a chamberfaround and above the shell F. Placed upon the cylinder H are one or more plates I. When desired, said plate or plates may be imperforate; but for certain uses they should be provided with numerous holes or openings. By placing one perforated plate over another, but without especial care that the perforations in one will coincide with those in the other, a more diffused passage of the hot air and gaseous products of combustion through said plate or plates will be secured. As the equivalent of a perforated plate or plates I one or more sheets of wiregauze may be employed.

The operation of the apparatus is as follows: The heat of the flame from the burner 0 causes in the usual manner the ascension within the chimney A of the hot products of combustion mingled with a relativelylarge volume of highly-heated air supplied to and around the burner in the usual manner. Simultaneous with this a volume of air less heated is carried upward through the chamber 1) and above the chimneyA mingles with the heated aeriformed products issuing from said chimney, the whole passing into the chamberf. From the chamber f, when the plates I are perforated, a portion of the highlyheated products passes through said plate I, the remainder passing outward radially from the top of the shell F and thence downward through the space between the sides of the The shell F, being capa-- f and heats the plate I aboveit, and when said plate or plates I, or in lieu thereof any suitable article to be broiled, toasted, or the like may be laid upon said plate or supported above the same by any suitable means. \Vhen the chimney is made of glass, all the light usually utilized is made available withoutinterfering with the utilization of the heat which accompanies the production of said light. When it is not desired to utilize the light, the chimney may be made of metal or some material less frangible than glass. In such case it is not necessary thata reflectingsurface be given to what is designated as the shade G. A defiect-ing-plateK may be interposed between the top of the shell F and the plate I above at such distance from the former as to permit the hot-air products of combustion, 850., to pass out into the chamberf, as described, the office of said deflecting-plate K being to more eifectuallydistribute the hot-air, products of combustion, &c., equally around the upper part of the chamberf. When desired, the lowermost of the plates I may be formed integral with the cylinder H, as shown in the drawings. The annular plates d may, When desired,be made of wire-gauze, or, if preferred, may be formed of series of inwardlyextending, projections to the shell F, it being suificient that the parts be of such character as to sustain the shell F in proper relation with the chimney and with the space b between said shell and the chimney.

What I claim as my invention is- 1. The combination, with a chimney A, of a shell F, constructed to be suspended from the chimney and concentric therewith and to provide a space I) between itself and said chimney, the deflecting-shade G, carried by said shell, a cylinder H, arranged around said shell with a chamberf between, and a plate placed above the shell and chimney, all substantially as and for the purpose herein set forth.

2. The combination, with a chimney A, of a shell F, arranged around said chimney with a space 5 between, a shade G, attached to said shell, a cylinder H, placed around said shell with a chamberf between, and a foraminated plate I, placed above the shell and chimney, substantially as and for the purpose herein set forth.

3. The combination, With a chimney A, of a shell F, provided with perforations ct and arranged around said chimney with a space 3) between, a shade G, attached to said shell, a cylinder H, placed around said shell with a chamberf between, and a plate I, placed above the shell and chimney, substantially as and for the purpose herein set forth.

4. The combination, with a chimney A, of a shell F, provided with perforations a and arranged around said chimney with a space 1) between, a shade G, attached to said shell, a cylinder H, placed around said shell with a chamberf between, and a foraininated plate I, placed above the shell and chimney, substantially as and for the purpose herein set forth.

5. The combination, with a chimney A, of a shell F, arranged around said chimney with a space 6 between, a shade G, attached to said shell, a cylinder H, placed around said shell with a chamber f between, a plate I, placed above the shell and chimney, and a deflecting-plate K, interposed between the top of the shell F and the plate I, substantially as and for the purpose herein set forth.

6. The combination, with a chimney A, of a shell F, provided with perforations a and arranged around said chimney with a space b between, a shade G, attached to said shell, a cylinder I-I, placed around said shell with a chamber f between, a foraminated plate I, placed above the shell and chimney, and a deflecting-plate K, interposed between the top of the shell F and the plate I, substantially as and for the purpose herein set forth.
