IMPROVEMENT IN GdRBURETTING GASES.

TO ALL WHOM IT MAIOONCERN: U I

Be it known that I, JOHN A. BASSETI, of Salem, in the county of Es sex, and State of Massachusetts, have invented certain new. ndpsei'ul improvements in Method of Garburetting Gases; anjlI do hereby declare that the following is'alul'? description of the same, reference being bad to the accompanying drawing, making a part ofthis specificatib'n I The object of this invention is to overcome the diificulties' which prevent a regular anduniform carburation of: gases for illumination, by what is known as the capiilary process, and also to arrangethat "the bulk of'the hydrocarbon liquid used for carburetting may be-away from the immediate vicinity ofthe carburettor, and avoid the necessity of having a large amount of a volatile fluid in the building tobe lighted. Itis well known that in the use oifibrous substances as a material todistributeand volatilize the hydrocarbon, that its capillary power is not constant, and. that it is liable to be clogged from the impurities ever present in coal gas; I In this invention the reservoir of hydrocarbon is placed above. the chamber in which-the cnrburation takes place, and a regular or intermittent flow is allowed to pass over and through the capillary material through which the gas passes to be carburetted.

The advantage of this. arrangement is that the supplyot hydrocarbon beiug uniform, the carburationis I fully under control and may be made perfectly regular, and a hydrocarbon of lower specific gravity and less volatilizing' power-may be used. I prefer to use in the.carburctting-chamber the porous carbon described in my patent of Mai-c114, 1852, because it possesses certain specific advantages over other capillary materials, but

any capillary substance may .be'used which 'will answer the purpose. V

The reservoir of hydrocarbon may be placed in any convenient position and connected with, the carburettor by a small tube, the quantity of hydrocarbon ndmittcd t o thecarburettor being regulated by a. cock. Below theearburettor a small reservoir may be placed to receive the overflow of hydrocarbon, and it should be arranged so as to be drawn oil' when required. i

The apparatus may be so arranged that the carburettor is simply an enlargement ofthe gas supply tube, so arranged that all the gas to be carburetted passes-through the enlargement. The hydrocarbon should be sup. plied from the reservoir in such proportions as may berequired to cnrburetthqmaximum quantity of gas which passes thrbug lrthe apparatus; Small carburettors may be arranged upon this plan so that the reservoirs may alternately fill and discharge, the inlet and outlet pipes bein'g'connected with stuffing-box joints. The reservoir at the top when e npty'is turned over, and the reservoir at the bottom which has become filled from the overflow becomes the discharging reservoir. v r i It will-be seen that one of the principal objects of this invention is to keep out of the building to be lighted the built of the hydrocarbon used for carburetting. '.l.lie presence of a large quantity of a volatile hydrocarbon in the building isdispensed with, and theresult produced. is more uniform and independent of variations oitemperature. If it 'is desired, the pipe conveying the hydrocarbon to the carburettor may be packed with a fibrous material, so that the flow may be-more perfectly regulated. V

In the drawings, A represents the carburettonpaclted with a capillary material; B, the reservoir for containing the hydrocarbon} G, the reservoir forrecoifving. the overflow; D, the inlet and E the outlet for gas;-x z,

the cocks by which the supply is controlled.

Having described my iuvention, what I claim,- and desire a patent for, is-

1. Th'earrangement of a hydrocarbon reservoir aboveand connected with a carburetting-chamber, either with or without capillary material, substantially as set forth.

2. The overflow receptacle connected with the carburettiug-chamber, for the purpose set forth. 3. The process'of .carburetting gases for illumination the method substantially as specified.
