APPARATUS FOR GARBURETING AIR AND GAS.

SPECIFICATION forming part of Letters Patent No. 312,186, dated February 10, 1885.

Applicniitn filed May .21, 1884. (X0 model) To all 2071,0727, it may concern:

Be it known that I, JONATHAN S. BUTLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Carbureting Air and Gas, of which the following is a specification.

The object of this invention is to provide novel, simple, and ciiicient means for carbureting atmospheric air and coal-gas by passing them through gasoline vapor or hydrocarbon fluid; to provide novel means in the carburetor for taking up and filtering the liquid gasoline or other hydrocarbon, and checking or retarding the flow of the vapor through the same; to provide novel means for agitating the liquid gasoline or other hydrocarbon, preventing the heavier portions of the same from settling to the bottom of the pans or vessels in the carburetor, and rendering the heavier grades of gasoline available, and to provide novel means for passing atmospheric air into the carburetor to be mixed with the gasoline or other hydrocarbon. These objects I accomplish in the manner and by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a vertical central sectional view of the carburetor; Fig. 2, a detached perspec tive view of one of the carburetor pans or trays; Fig. 3, a perspective view with parts broken away, showing the carburetor connect ed with the air-supplying devices, and Fig. 4 a detached perspective view of the top wall of the air-holder.

In order to enable those skilled in the art to make and use my invention, I will now proceed to describe the same in detail, reference being made to the accompanying drawings, where the numeral 1 indicates the carburetor case or box closed to the external atmosphere, and provided with a valved outlet-pipe, 2, for carrying off the carbureted gas to a gas-holder. The case or box incloses a series of pans or trays, 3. arranged one above the other, and closely fitting the interior of the case or box, so that gas or air entering through the inletpipe 4 at the bottom of the case can only rise from one pan to the other by passing through orifices 5 in horizontal end flanges, 6, of the pans, the flanges alternating, so that the airoritices also alternate.

To the under side of each pan is secured a drooping absorbent, 7, of loose-textured cloth or other similar material, which is suspended from the ends of the pans in such manner that hanger, S, carrying a revolving agitatingwheel in such manner that the wheel of one pan extends into the pan below, the arrangement being such that the wheels alternate and are revolved by the ascending currents of air or coal-gas passing through the orifices'5 and through orifices 9 in the end walls of the pans, thereby continuously agitating the liquid in the pans and preventing the heavier particles of the gasoline from settling to the bottom of the pans, while such agitators render the heavier grades of gasoline available. As the pans are not simply open surfaces, but fit the walls of the case, it follows that the entering air can only rise through the orifices 5 and 9, and consequently the operation of the agitators is insured.

\Vhere atmospheric air is used in connection with my improved carburetor, I provide an inverted cup-shaped air-holder, 10, capable of rising and falling within a cistern, 11, parti ally filled with water or other liquid; and the inlet-pipe4 to the carburetor is connected by a pipe, 12, with a stand-pipe, 13, rising within the cistern and air-holder, with its upper open end abovethe level of the liquid seal in the cistern. The air-holder has its top plate, 14, provided with means whereby air can be admitted to the holder, and this means preferably consists of an orifice, 15, in said top plate, adapted to be opened and closed by a valve plate, 16, hinged to one edge of the orifice and connected with one end of a coiled or other spring, 17, the other end of which is connected with a cross-bar, 18, on the top plate. This cross-bar carries friction-wheels 19 at its outer ends, which travel on vertical guide-standards 20 in such manner that the rising and falling movements of the air-holder are steadied and rendered free and easy. The spring serves to close the valve after sufiicient air has been admitted to the air-holder.

The air-holder can be raised by weights or other mechanical devicessuch as a Windlassas shown in Fig. 3.

I am aware that heretofore air has been forced through a case containing vessels for holding hydrocarbon fluid, the air in its passage acting to revolve a wheel in a horizontal direction, from which depend fingers to agitate the fluid in the vessels; such, therefore, I disclaim.

Having thus described my invention, what I claim is 1. The combination, with the carburetorcase and air or gas forcing mechanism connected therewith, of a pan fitting the interior of the case, and a winged wheel journaled to revolve in a vertical plane with its wings in the fluid contained in the pan, substantially as described.

2. The combination, with the carburetorcase having an inlet for atmospheric air or coal-gas, ot' a series of pans fitting the case, one above the other, and provided with alternating end orifices, and the alternately'arranged agitating-wheels supported, respectively, in the end portions of the pans, and revolved by the ascending air or gas passing through the said end orifices, substantially as described.

3. The combination, with the carburetorcase having an inlet for atmospheric air or coal'gas, ot' pans closely fitting the case, one above the other, and provided with end orifices, hangers suspended from the bottoms of the pans, and agitatingwheels suspended by the hangers in the pans respectively, and re volved by the ascending currents of air or gas passing through the end orifices, substantially as described.

4. The combination, in a gas-carburetor, of a case having an inlet for atmospheric air or coal-gas, a series of pans fitting the case, one above the other, and provided with alternating end orifices, absorbents drooping from the under sides of the pans, so that one extends into the pan below it, and revolving agitating-wheel s supported alternately in the ends of the pans, substantially as described.

5. The combination, with the carburetorcase, the pans therein, the agitating-wheels, and suitable absorbents, of acistern, a rising and falling air-holder therein provided with means to admit air therein, and pipes connecting the carburetor-case with the air-holder, for introducing air into the carburetorcase and revolving the agitating-wheels therein, substantially as described.

6. The combination, with the carburetorcase, the pans therein, the agitating-wheels, and suitable absorbents, of the cistern, the guide-standards, the rising and falling airholder having an orificein its top and a crossbar carrying rollers, a valt e for opening and closing said orifice, and a spring connected with the valve for throwing it closed, substantially as described.
