' Application filed July 19, 1900. Serial No. 24,188. a) model.)

To all whom it may concern:

Be it known that I, CHARLES I. TENNEY, a citizen of the United States, residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented certain new and useful Improvements in Carburetors; 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.

This invention relates to apparatus for the production of illuminating-gas from a liquid hydrocarbon, such as gasolene, and has for its object to increase the efficiency of such apparatus and improve the quality of the product.

The nature of the invention will fully appear from the description and claims following, reference being had to the accompanying drawings, in which Figure l is an ideal section of apparatus embodying my invention. Fig. 2 is a vertical section through the middle of the carbureter, and Fig. 3 is a horizontal section of the carbureter below the line a b.

In the drawings, A denotes a cistern or tank supplied with water. B is a bell suitably mounted to rise and fall therein, according to the volume of air within it. In the bottom of the tank is placed a carbureter O, which communicates with the interior of the bell by a stand-pipe D, extending above the surface of the water. By means of a looped pipe E air is forced into the bell and thence into the carburetor by a suitable blower. (Not shown.)

The details of the carbureter are illustrated in Figs. 2 and 3. G is a shell or case, preferably provided wit-h an inclined top, in the apex of which is attached a pipe F to carry away the gas generated therein. Near the top is a horizontal diaphragm O and between this and the bottom are alternating partitions C to give the air passing through the gasolene in the carbureter a circuitous course,and thus carburize it. The course of the air is The air enters the carburetor at pipe.

D', and after traversing all the partitions therein passes into the upper part of the earbureter as gas through a suitable hole G.

Without which it is impossible to produce gas,

of uniform quality.

1 At a suitable distance from the carbureter audits containing-cistern is placed the gasolene-reservoir H. This is provided with a suitable supply-pipe I, and also with means for drawing out its contents, such as the forcepump J illustrated. In practice the pump is provided with two suction-pipes, the pipe K extending to the bottom of the reservoir, so as to draw out the heavier oil settling to the bottom, and a shorter pipe K, terminating some distance above the bottom of the reservoir and designed to supply a good and practically uniform quality of gasolene to the carbureter, or through a return-pipe L, at-

tached at one end to the pump and the other end communicating with the pipe F. Connecting with the pipe L is a Waste-pipe M, provided with a suitable stop-cock M. Stopcocks are also provided at L, K and K with suitable means for opening and closing the .two latteras, for example, the lift-rods K.

It will be seen that the reservoir H is placed with its bottom below'the level ofthe bottom of the tankA and the carbureter thereon, and its top higher than the top of the carbureter; The pipe F communicates with the upper part of the reservoir. From the bottom of the carburetor a pipe N leads to the bottom of the reservoir and is provided with a stopcock N, opened and closed by means of a long-stemmed wrench O.

The operation of the apparatus is as follows: The reservoir and carbureter being empty, the reservoir is first filled with gasolene up to a certain predetermined line corresponding with the desired level in the carbureter, (the apparatus for gaging this depth not being shown,) the stop-cock N being open. At the desired level the stop-cock is closed and the filling of the reservoir continued as much as may be desired. As the gasolene in the carbureter is consumed a new supply is introduced through the pipes K, L, and F by means of the pump J or equivalent apparatus. In this Way the carbureter is continually supplied with gasolene of a suitable quality for service, not the very lightest, at the top of the reservoir, nor the heaviest, which is at the bottom, but a good uniform quality. When after long service the carbureter shows signs of having itself received a deposit at the bottom of unsuitable matter, as is inevitable in all apparatus of this nature, it may be drained off into the reservoir by opening the stop-cock, the level of the gasolene in the reservoir being of course below the bottom of the carbureter. Thence it may be pumped off through the waste-pipe by closing the cocks K and L. As the upper portion of the reservoir is higher than the top of the carbureter an air-space or rather a space for gas is provided in such reservoir, so that as the gasolene is drawn out its place is occupied by inflowing gas and no vacuum is created. So, on the other hand, when the reservoir is recharged the gas simply flows out of the reservoir to make way for the gasolene poured in.

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

In a gas-machine, the combination of acarbureter, a gasolene-reservoir lower at the bottom and higher at the top, respectively, than said carbureter, a pipe connecting the lower portions of both carbureter and reservoir, a stop-cock for the same, a pipe connecting the upper portions of both carbureter and reservoir, a pump having one suction-pipe terminating near the bottom of the reservoir and another terminating some distance from said bottom, stop'cocks for said pipes, a supply pipe leading from the pump to the carbureter, a waste'pipe communicating also with said pump, and stop-cocks for both such pipes,

'substautially as and for the purpose set forth.

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

CHARLES I. TENNEY. Witnesses:

WILLIAM NETTLETON, W. J. HUDSON.
