REUBEN F. HUGHES, OF CINCINNATI', OHIO.

GAS-CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 248,750, dated October 25, 1881.

Application iled March 18, 1881.

To all whom t may concern Be it known that I, REUBEN F. HUGHES, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gas-Oarburetors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Myinvention relates to self-feeding gas-carbureting machines; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claim.

The objects of the invention are, first, to avoid all systems of levers whereby the operation of the valve in automatic or float feeders is varied by the specilic gravity of the lowest body of oil in the carbureting-chambers, and to provide a direct-acting stem connecting the iloat to the valve, said stem extending through an enriching chamber or chambers between the carbureting and float chamber in which the forced air is admitted and the volume of oil in the reservoir above; second, to supply air to the reservoir to compensate for displaced gasoline, said air being fed from the air-inlet, thus keeping the reservoir in condition to feed down at any time, and preventing the escape and waste of vapor from the hydrocarbon fluid contained in the reservoir; third, to provide a lower iioat-chamber, which serves as an air inletting chamber and a carbureting-chamber, the loat in which is connected by a direct stem to a valve,which is seated properly in the bottom of a reservoir forming the upper chamber, and between these two chambers one or more enriching-chambers, connected together and to the tloatchamber by pipes or tubes extending sufciently far above the floors of these intermediate or enriching-chambers to allow a proper quantity of the richer gasoline to be retained in cach chamber and this quantity of gasoline to be controlled by the float and valve.

To enable others skilled in the art to make and use my invention, I will describe its manufacture, construction, and mode of operation, and to this end refer to the accompanyingdraw- (No model.)

ings, which form a part of this specification, and infwhich- Figure l is a vertical longitudinal section, showing one intermediate or enriching chamber; Fig. 2, a horizontal section through the line .fr x of Fig. 1; Fig. 3, a horizontal section through the line y y of Fig. l; and Fig. 4, an enlarged sectional view of the valve and its seat.

In the said drawings similar letters of reference indicate like parts in all the figures.

Referring to the iigures, A represent-s the lower or float chamber, having an air-inlet, a, connected with the forced-air pipe, b, which is, in turn, connected to any air-propelling motor, and having a usual cock-outlet near the bottom to allow the devaporized or poor gasoline to escape. This chamber is of ordinary and well-known construction, adapted to afford a maximum of carbureting power with a minimum of space and hydrocarbon liquid, and it is adapted to receive a float, O, having a stem, O', which, passing upward through a neck, d, in a diaphragm, D, is secured to a valve, E, in a direct line, said valve E having its seat E formed in the diaphragm F, which comprises thebottom of the reservoir or store-cham ber F For convenience I will describe but one intermediate chamber, but it will be understoodthat two or more may be used.

The weight ot' the loatO serves to open the valve and admit the gasoline into the enriching-chamber G,which is connected to the floatchamber by a tube, g, extending sufliciently above the door to allow such enriching-chamber to at all times have a proper quantity of gasoline retained therein.

With their lower edges extending slightly below the horizontal plane of the tube g, and secured to the diaphragm F above, are hanging plates, G', between which and the cylinder are openings at alternate ends which delay thel flow of air to insure its more perfect carbureting, and an exit, g', allows its conduction to the burners.

Leading from the air-induction pipeB to the reservoir F', above the surface of the volume of oil, is a pipe, H, which allows the inlet of air to take the place yof the displaced gasoline and to prevent the waste of vapor. The reservoir has proper facilities for filling.

From the foregoing description, in connec- IOC tien with the drawings, the operation of the machine will be obvious.

Various modifications may beniade without departing from the principle or sacrificing the advantages of my invention, the essential features of which are the direct-acting valve,the connection between air-inducting pipe and reservoir, and the general construction and arrangement of the whole.

fhat l claim as new, and desire to secure b v Letters Patent of the United States, is-

The l'ierein-described gas-carburetor, composed ofthe vessel divided by the diaphragins D and F into a floatchainber, having` the airinlet a, connected with the forced-air pipe b,
