v duce a flame available for heating boilers or .est in its middle.

furnaces.

The accompanying drawing represents, in section and partly in elevation, apparatus for this purpose according to my invention.

Within a fire-chamber, which may be of brick-work, A, or might be the fire-box or flue of a boiler, I suspend a retort, R, of approximately hemispherical shape, with its bottom somewhat rounded, so as to be thick- From a water-cistern I connect a pipe, W, which, after passing in several convolutions around the retort,en'ters the retort near the bottom. From the upper part of the retort I lead a pipe, S, to an injector-nozzle, J. and from a cistern containing the oil or liquid hydrocarbon I lead a pipe, 0, to the annular space K surrounding the nozzle J. I provide under the retort a shield, P.

The action of the apparatus is as follows: The retort R is in the first place heated by burning under it any convenient combusti ble, such as a mass of shavings or fibrous materials soaked in oil, and then a small quantity of water is admitted by the pipe W, and of oil or hydrocarbon liquid by the pipe 0. The water is converted into steam, and this passes by the pipe S to the nozzle J, whence it issues as a jet carrying with it through the mouth L the oil or hydrocarbon liquid which is broken into spray and dashed against the bottom of the retort. The jet also causes a current of air to enter by the tubular neck or mouth T of the shield, and the mixture of the spray with the steam and air being ignited, a flame is produced which heats the retort and the pipes. Shortly after the commencement of the action, when the retort and I pipes have become sufficiently heated, the

supply of water and of oil or hydrocarbon I powerful flame can be maintained, available V for heating boilers or furnaces.

I am aware that it has been proposed to construct hydrocarbon-burners of coiled pipes above an imperforate shield combined with water, steam, and oil pipes and an injectornozzle under the shield, so that a spray of hydrocarbon mixed with steam and air and ignited is spread by the shield and caused to heat the coiled pipes for generating the steam to be used. Such, therefore, I do not broadly claim.

Having thus described the nature of my invention and the best means I know for carrying the same into practical effect, I claim- 1. The combination, substantially as hereinbefore described, of a retort, a water-pipe connecting with the interior of the retort for delivering water thereinto, a shield arranged below the retort and having an opening therein, a pipe connecting at one end with the interior of the retort and provided at the other end with injector-nozzle arranged in the opening of the shield for delivering steam from the retort to said injector-nozzle, and a pipe for delivering liquid hydrocarbon about the said nozzle in the opening of the shield, as and for the purposes set forth.

2. The combination, substantially as hereinbefore described, of a retort, a water-pipe connecting with the interior of the retort for introducing water thereinto, a shield arranged under the retort and constructed with a central pendent tubular neck, a pipe connected at one end with the interior of the retort and at the other end provided with an injectornozzle arranged within the tubular neck of the shield, and a 'pipe for delivering liquid hydrocarbon about the said nozzle, substantially as set forth.

3. The combination, substantially as hereliquid hydrocarbon about the said nozzle, as inbefore described, of a retort, a pipe c0nvo and for the purpose set forth. luted around the retort and connected with In testimony whereof I have signed my the interior thereof for introducing water name to this specification, in the presence of 5 thereinto, a shield arranged under the retort two subscribing witnesses,this 4th day of July, 15
