ceusunnrnu Specification of Letters Patent.

Patented Dec. 31,1912.

application filed January 9, 1912. Serial No. 670,145.

I To all whom. it may concern: 1

Be it known that 111,,Anrrrun T. Burr-WEN, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented CPl11ll1 new and useful improvements in- Carbureters, of which the following is a specification.

My invention relates to 'earbureteraand my object to provide a simple and ellicient apparatus of this character which may be employed 'toatlvantage in supplying gaseous fuel to the motors of automobites, to the end that the carburet'ers now in general. use for that purpose may be dispensed with.

By employing my apparatus, an adequate amount of fuel-of uniform richness is al ways insured, and'in order that the invention may be fully understood, reference will now be made to the accompanying drawing, in which:

Figure 1 is a-sectional View of asupply tank provided with my apparatus. Fig. 2 is a perspective of a float, forming an important feature of the invention. Fig. 3 1s a cross section of the at, on line HI- HI of Fig. 1. Fig. 4: is a perspective of a wick, a plurality of which are employed in carrying out the invention.

1 designates a supply-tank for holding .gasolene or other hydrocarbon oil to be convertedinto gaseous fuel. Said tank is provided with an inlet 2,,throu gh which it may be supplied, said inlet beingnormally closed by a removable cap 3.

4- designates thefloat, forming one of the important features ot'the invention. Said float embodies a receiving-chamber 5, a discharge chamber 6, two air-chambers 7 and a wick-chamber 8. The receiving-chamber 5 is located at one endof the float, and the discharge-chamber 6, is located at the opposite end of said float, while the wick-chamher 8 extends throughout the length of the float between the two air-chambers 7. The receiving-chamber 5 is provided at its upper side with a nipple 9, having a hose connction 10, which hose is connected at its upper end to an inlet-pipe 11, extending through the adjacent end of tank 1, and provided with an air-receiving funnel 12, having a strainer 1.3 to intercept dust or 0ther','foreign matter which might otherwise entersaid funnel with the air; vThe inlet pipe 11 is, provided with a check-valve 14,

' adapted to open toward the hose 10 When the apparatus is in operation. The air entering the receiving-chamber o is ,permitted to flow outward therefrom into the wickchamber 8 through a horizontal row of inlet-ports 15, in the vertical rear wall of said chambers. The discharge-chamber 6 communicates with the wick-chamber 8 through a horizontal row of inlet ports 16, in the vertical front wall 913' said chamber 6. The upper portion of the discharge-chamber 6 is provided with a nipple 17, having a hose-connection l8, communicating with an outlet-pipe. 19, leading to the motor or other point oftu'se, not shown. -Back-pressure from the outlet-'pipe 19 to the dischargechamber 6 is prevented by a check-valve 20, communicating with said outlet-pipe. Outlet-pi e 19 is provideiif with an air-intake 21, provi ed with a valve 22 to control the flow of air therethrough.

'23 designates a plurality of wicks consisting of any suitable absorbent material,

each wick being stretched on a suitable frame 24. side in the wick-chamber 8 as-shown in Figs. 1' and 2, and are supported in said wick-chamber .bya pair of flanges 25, re-

movably secured to thebottoms of the air' the intake 21, the amount of air being regulated by the valve 22, which in turn may be regulated from a point adjacent the seat of,

an automobile when the apparatus is installed on a vehicle of that character. The air-chambers 7 are, preferably, so proportioned as to support the,upper half of the float above the level of the oil in tank 1, so that it will not obstruct the passage of the air through the upper portion of the wick Frames 24 are placed side by l chamber, and at the same time, seal the air the, tank 1.

frompassing from said wick-chamber into Although the float is free to move up and down with the level of the oil within tank connections between the inlet and the re- 1 '1, it fits the interior of said tank sufficiently changes as properly fall within the spiritand scope of the appended claims.

Having th'usdescribed my invention what I claim and desire ent, is:

1. In combination with a tank, a float therein composed of a pair of spaced transverse receiving and discharging chambers 'located'at opposite ends of the tank and a pair of spaced longitudinal side air chambers that are connected to the ends of the receiving and discharging chambers, flanges carried by the bottoms of the air chambers and extending inwardly. to project in the space between said air chambers, wick frames having their bottoms seating on said flanges and located between the inner side faces of the air chambers, the inner walls of the receiving and discharging chambers being formed with openings, an air inletin the tank, an outlet, and flexible hose to secure by Letters Patopenings which face each other and are 10- cated intermediate the tops and bottoms of said inner wallsto provide a direct hori- Zontal passage through the space defined by the float, which openings directly communicate with the space bet-weensaid chambers,

a series of wicks supported by the float and located in said space, a flexible pipe directly connected at one end to the receiving chamber and at its opposite end to the tank for supplying air to the interior of the receiving chamber and a flexible pipe directly connected at one end to the discharging chamber and at its opposite endto the tank for exhausting the fuel from the discharging chamber.

In testimony whereof I aflix my signature, in the presence of two witnesses.
