GEORGE IIATHORNE, OF NFAV YORK, N. Y.

GAS-BURNER.

SPECIPICATIONforming part of Letters Patent No. 351,052,dated October 19, 1886.

Application filed March 12, 1886. Serial No. 194,984.

To a/TZ whom it may concern.-

Be it known that I, GEORGE HATHORNE, of the city and State of New York, have invented an Improvement in Gas-Burners, ofwhich the following is a specification.

These improvements are applied to that class of burners known as regenerative gasburners, in which the air and gas are heated, and the flame burns downwardly and the products of combustion pass up through a central chimney; and said improvements consist in the combination of devices hereinafter set forth, whereby the burner is made more efficient, and the light is more evenly distributed, and access for cleaning or lighting is more convenient.

In the drawings, Figure 1 is an elevation, partially in section, of my improved gas-burner. Fig. 2 is a section in larger size of the burner, reflector, and the ring that holds the glass globe.

The interior portions of the lamp are similar to those shown in LeLtcrs Patent N 0. 299,660, in which the gas enters by the pipe 13 into an annular chamber, and descends by pipes within the tubular chimney, and thence passes by lateral tubes D to the annular gas-burner T, from which the gas issues through the jet-holes a, and descends outside the cylinder E of refractory material, and the air passes up inside the case I through holes in the upper part of the case F, and descends within such case F and passes at each side of the annular burner T to supply air to the flame.

I make use of an inverted conical reflector, 1, that surrounds the lower end of the case F and extends out to the glass globe H. The object of this deviccis to lessen the area of the shadow cast from the lamp on the ceiling of the room to produce a reflecting surface that throws the rays oflight off horizontally and upwardly and increases the efficiency of the light.

I secure the edge of the globe H within a metallic rim, I, by screws 5 that hold the flange of the globe, and this ring is hinged at 6 to the upper edge of the reflector 1, and at the opposite side of said reflector I provide a latch, 8, that is hinged at the upper end to the said rcflector and catches below the rim 4. By this means I obtain access to the globe for cleaning the same, and also for lighting the gas, and when the said gas is lighted it is only necessary (No model.)

to swing the globe back to its place. The finger 36, projecting from the rim 4 adjacent to to the latch 8, is convenient for moving the ring and globe.

I make the entire globe of ground or frosted glass, except a narrow band, 34, (see Fig. 1,) that is left plain around the middle portion of the globe that is slightly below the lower end of the refractory chimney E, so that the end of the flame can be observed where it turns around the said lower end of the chimney, and the light as it passes both downwardly and upwardly will be rendered agreeable and mellow.

I inclose the upper part of the chimney G with a case of ornamental sheet metal, there being a dome, 10, collar 11, tube 12, and flaring crown 13, and these are at a sufficient dis tance from the chimney to prevent injury or discoloration from the heat, and I admit air into the lower end of such case for the twofold purpose of keeping the case cool and preventing discoloration, and for promoting the draft of the lamp by the ascending current of air passing up at the sides of and above the top end of said chimney.

I make the suspending-frame of tubes the side pieces, 15, being parallel and screwed into the square junction pieces 16, and the pipe at the upper end is bent outwardly into a circular head, 17, to which the center piece and gaspipe 18 are attached. The opening for the gas is made through one of the junction pieces 16, and the cook 20 serves to regulate the flow of gas. The bell 24 is suspended, as usual.

I surround the casing I with a band, 30, of

ornamental sheet metal, having the inner sur-' face polished so as to reflect light, and I place an inverted conical reflecting-ring, 31, preferably of porcelain, inside the said band 30, and this reflectorrests upon the screw-su )ports 82, that project from the lower part of the casing I, and this reflector prevents the objectionable appearance of the casing I, and the'light is reflected from the interior of the band back upon the inverted conical reflector 31, thereby increasing the efficiency of the lamp.

I claim as my invention 1. The combination, with the depending annular gas-burncr T, cylinder E, of refractory material, and the escape-chimney for the pro ducts of combustion to pass through the annular burner, of the conical air-shield I, and the cylinder F, with which such shield I is connected at its upper end, and the reflector 31, formed as an inverted cone, and supported at 5 its inner edge by projections upon the base of the air-shield I, and the globe I-I,'substantially as specified.

2. The combination, with the depending a11- nular gas-burner and the chimney Within the 10 same, of the inverted conical reflector 1 around ring around said reflector 1, the shield I, the inverted conical reflector 31, and the band 30, of reflecting metal, around the outside of and supported by the reflector 31, substantially as set I 5 forth.

Signed by me this 3d day of March, A. D. 1886.
