CARBURETER.

SPECIFICATION forming part of Letters Patent No. 745,489,

dated December 1, 1903.

Application filed September 20, 1902. derial No. 124,211. (No model.)

T0 al whom it may concern:

' Be it known that I, GEORGE S. GOSLEE, a citizen of the United States, residing at Mason City, in the county of Gerro Gordo and State of Iowa, have invented certain new and useful Improvements in Carburetors, of which the following is a specification.

This invention relates to the production of gas for general consumption, and has for its object to produce economically a good and uniform quality of illuminating-gas from any suitable liquid hydrocarbonsuch, for exam ple, as gasolene or naphtha.

The nature of the invention will clearly appear from the description and claims following, reference being had to the accompanying drawings, in which Figure 1 is a vertical section of apparatus embodying my invention, and Fig. 2 isa sectional view of the device for regulating the supply of gasolene to the'tank which comm unicates directly with the generator.

Referring to the drawings by letter, A designates a cistern containing a sufficient supply of water to completely submerge the storage'tank B, supply-tank G, and generator D. The object of this is to maintain as nearly a uniform temperature as possible, and thus secure the greatest possible uniformity in the quality of the gas produced. S is a drier through which the gas passes from the generator and is mounted above the floor F, which is some littledistance abovethe top of the cistern. k

The storage-tank is filled through a pipe G, the lower end of which is near the bottom of the tank, as shown. From this storage-tank the supplytank 0 receives its contents through pipes H, H, and H by the action of a pump 1. In the drawing the simplest type of a piston-pump is illustrated, though in I practice a rotary pump of. a common and wellknown type may be used, driven by the same power that drives a blower for supplying air to the generator. As such pump, motor, and blower are of well-known construction and form no essential part of this invention it has not been deemed necessary to illustrate them. Another pipe J also communicates with the P p serves and the storage and supply tanks and for the preliminary filling of the supply-tank and also for the emptying of the same whenever it may be necessary or the drawingoff of the heavier oil at the bottom of the supply-tank. This is done by closing the valves H and H opening the valve J and the bib J and operating the pump. The supp] y-tank communicates with the generator bya pipe K tapping the suppl y-tank near the surface of its supply of gasolene, and thus carrying the light and volatile product into the generator. The bottom of the generator communicates with the lower part of the supply-tank, which is considerably lower than the bottom of the generator, by a pipe K. This allows the heavier residuum from the generator to flow back into the supply-tank, whence it may be pumped out, as above described. The upper parts of the supply-tank and generator connect by a pipe K the purpose of which is to equalize the pressure as between the generator and supply-tanks.

In the supply-tank is mounted a float M, having a vertical stem M, terminating in a needle-point M This needle-point fits a small hole in the pipe-fitting H as shown in Fig. 2. \Vhile the apparatus is in operation, the pump causes a continuous flow of gasolene through the pipes H, H, and H In case the supply in the supply-tank falls be low a certain predetermined level the depression of the float opens the hole normally closed by the needle-point, and gasolene then flows down the pipe H to supply the deficiency. As soon as the liquid rises to the normal level in the tank the needle-point closes the hole and the flow ceases. By this means a certain level of liquid is always maintained in both the supply-tank and the adjacent generator, and in the process of carburizing the air has always to pass through the same depth of gasolene with corresponding uniformity in the result.

The carburetor or generator comprises a tank D, preferably cylindrical, a central airpipe D, and a series of horizontal disks or diaphragms D and D The former are provided with a central hole somewhat larger than the air-pipe, and the latter have a central hole fitting closely around the air-pipe, but are of smaller diameter than the inside of the tank D, thus leaving a space between for their outer edges and the tank through which the air may pass. The air is thus forced in a circulatory zigzag course through the carbureter from bottom to top, whence it passes out through a pipe N, carburized by reason of its course between the plates in the carbnreter.

In the pipe N is a trap Nfor condensation from the ascending gas. A pipe 0 leads from the bottom of the trap back to the carbureter. This is provided with a check-valve O, which admits of the condensed moisture flowing back into the carbureter, but prevents the movement of gas in the opposite direction.

The upper parts of the supply-tank and carbureterare connected by a pipe P to equalize the pressure as between the tank and carbureter and prevent a partial vacuum in the former. I

A pipe Q connects the pipe N above the trap with the storage-tank for a'similar purpose. The vertical portion of this pipe P permits the measurement of the gasolene in the storage, as by the insertion of a rod or the like.

Before reaching the gas-main R the gas passes through a drier S, fitted with a series of diaphragms S and 8*, similar to those in the carbureter, to give the gas a circular course. The spaces between the plates are filled with some suitable absorbents-such as coke, for example. I

The apparatus as thus constructed is adapted to the economical production of a gas of high illuminating power and very uniform quality, characteristics which are of the utmost importance in the production of any gas and are especially difficult of realization in the management of gas from gasolene and like hydrocarbons.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a gas-machine, the combination of a storage-tank, a supply-tank at a lower level, a pump adapted to draw liquid from'the storage to the supply tank, a pipe communicating with said pump, with one terminal near the bottom and the other near the top of the storage-tank, a pipe leading from said storpipe to the supply-tank, and means for automatically age-tank substantially as described closing said supply-tank pipe, as the liquid in said tank reaches a certain level.

2. In a gas-machine, the combination of a storage-tank, a supply-tank, a pipe leading from near the bottom of the storage-tank to the pump and thence to the top of said tank, an intermediate pipe connecting the storagetank pipe withthe supply-tank, a float in said supply-tank, and a stem connecting with said float, with a needle-point adapted to close said supply-tank pipe, whereby the supplytank is fed by the overflow from the storagetank pipe, and a uniform level of liquid is maintained therein.

3. In a gas-machine, the combination of a storage-tank, a supply-tank, a pump, a pipe communicating with said pump, with its suction end near the bottom of the storage-tank and its discharge end opening into the top thereof, a branch therefrom leading downward to the supply-tank, a valve therein, a needle-point to close the same, with a stem extending to a float inside said supply-tank, a float, and another branch pipe openinginto the lower part of the supply-tank, a valve therefor, and valves for the storage-tank pipe, substantially as and for the purpose set forth.

4. In a gas-machine, the combination of a carbureter, a trapped gas-pipe leading from the top thereof to the bottom of a drier, a drier substantially as described, and a drainpipe leading from the bottom of the trap back into the carbureter,withacheck-valve therein, substantially as and for the purpose set forth.

5. In a gas-machine, the combination of a storage-tank, a supply-tank, a carbureter, a drier and a trapped pipe connecting the carbureter and drier, supply-pipes leading from the storage to the supply and from the supply to the carbureter, and pipes connecting the upper part of the supply-tank with the upper part of the carbureter, and the upper part of the storage with the trapped pipe, substantially as and for the purpose set forth.

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