IMPROVEMENT IN APPARATUS FoR cARBuRETING AIR.

Specification forming part of Letters Patent No. 115,988, dated June 13, 1.871; reissue No. 4,476, dated July 18, 187.1.

To all whom it may/concern,- p

Bc it known that I, BYRON SLoPER, of St.

Louis` in the county of St.. Louis and State of Missouri, have invented a new and useful Improvement in Air Gas-Lamps, of which the following is a full, clear, and exact description.

The nature of my invention relates to that class of gas-machines known as gravity-machines and it consists in so arranging andconstructing the carbureter, in connection with an automatic valve for admitting and shutting 011'. theair, that said carbureter may be heated without any liability of the gas to escape from the carbureter and endanger the apartment in which it is placed by the formation ot' an explosive mixture.

The gravity machines heretofore constructed have proved defective and dangerous for the reason that the gas would escape troni the` airinlet aperture when the apparatus was idle, and it was also impracticable to use heat in connection with such apparatus for the reason that it would increase the volume of vapor in the carbureter to such an extent that it would overiiow though the air-inlet when the machine was in use, and thus endanger all surrounding objects, by the formation of an explosive vmixture in the roomin which it was placed. Besides, whcnthe machines heretofore employed Were not in use, constantly evaporating room through the air-inoffensive odors. It is of and escaping into the let," thus giving rise to the utmost importance, in most instances, to apply heat to the carbureterin order tobe enabled to use oils of a low gravity where the high-gravity hydrocarbons cannot be obtained, and also to use the highv4 gravity of oils in cold weather, which do not readily volatilize at low tempera-v tures 5 and also it is an object of importance for the reason that, under all circumstances, by the aid of heat, the air willbe much more highly carbureted, and thus the danger of formingexplog sive mixtures in the apparatus rendered less likely, since such mixtures are onlyformed when the air is lightly carbureted. Again, it is absolutely necessary to employ heat when the apparatus is used as a lamp, where only a short fall yapor under ordinary`l circumstances does not possess suiicient gravity to give a suicient light.` For the above reasons all former apparatus have impracticable; but by my invention all these dif eulties are overcome.

a view of the valve-box,

bureter, and its lower 'edge extends to near the bottom, so as' to be covered by or immersed in the hydrocarbon liquid when the carbureter is charged. Extending from the top ofthe vessel ,B down through its center is a Itube, D, which terminates near the bottom -of said vessel, and

to the upper end of which is attached, by means of Aa screw-thread or otherwise, a valvecap, E, in which the automatic valve F works. Said automatic valve consists of an annular disk, the aperture through which comes directly over the opening o'r tube communicating with the carbureter.' Said valve rests on an annular valveseat, H, formed by the bottom of the valvebox or cap E, through which is made a series or' apertures, h h, establishing a communication with the interiorof the valve-box and the atmospheric air when the valve rises lfrom its seat. OverV these apertures the annular valve rests, andprevents communication with the atmosphere when the apparatus is not in use, and the escape of gas when there is any pressure from within by expansion. Near the top of the tube D is an aperture, d, opening into the center of`the winding passage O, and providing an inlet for air, which passes from the center of said passage to its outer edge, becoming carbureted in its coiuse, and escaping into'the service-pipe L, which extends fronl said carbureter at a point above the level of the hydrocarbon liquid and terminates -in proper burners below. These burners are arranged so as tocome beneath the carbureter in order to heat it, or the carbureter maybe heated in any other convenient manner. Between said burners and the carburetor, in the service-pipe, is placed a packing of Wire or wire-gauze, or other suitable material, M, which acts upon the principle of the safety-lamp and prevents an y back iloW oi' liame to the carbureter. In the tube H is placeda heat, K, attached to a rod, 7c, extend removed, showing' and the cock. at
