HENRY OALLAHAN, OF DAYTON, OHIO.

CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 550,317, dated November 26, 1895.

Application filed May 14,1895. Serial No. 549,335. (No model.)

To all whom it may concern:

Be it known that I, HENRY CALLAHAN, of Dayton, county of Montgomery, State of Ohio, have invented a new and useful Improvement in Carburetors; and I do 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 the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in carburetors, and has for its object to provide means for feeding the hydrocarbon fluid to the generator in a systematic and uniform manner, to the end that the use of valves or stop-cocks to regulate said feed is dispensed with, thus avoiding a troublesome and undesirable feature in carburetors. The construction and arrangement of the same will be fully described in the following specification, taken in connection with the accompanying drawings, of which Figure 1 is a side elevation of the carburetor, the inclosing case being removed from that side to show the relative positions of the pans. Fig. 2 is a section through the reservoir on the line a CL of Fig. 1. Fig. 3 is an elevation of the reservoir end of the carburetor.

Similar letters of reference indicate correspondin g parts throughout the several views.

A designates the carburetor, comprising a number of receptacles or pans I), placed one above the other, and over each of which are depended rows of Wicking a or other similar substances which attract the oil and through which the air circulates in contact with the oil and the vapor arising therefrom. This is a well-known feature of carburetors, and the arrangement and attachment of said wicking will be made. When the parts are thus united,

they appear as shown in Fig. 1, and are adapted to be inclosed in the ground in the usual manner.

provided with floats, valves, &c.

Referring, further, to the reservoir, d designates a number of stationary pans placed one above the other. These pans are each of a size similar to the evaporating-pans b and are arranged on a horizontal plane therewith that is to say, each of said reservoir-pans (Z is on a horizontal plane with one of the evaporating-pans and communicates therewith by means of the tubes e, hereinbefore' referred to. Each respective tube 6 lies near the bottom of the pan d, so that they may convey the oil from the bottom of said pans. This is essential, as thereby a constant supply of fresh oil is fed to the evaporating-pans, which in sures a more uniform generation and a higher standard of gas. In other words, the purest part of the 0ili. c. that lying on topis not fed to the evaporating-pans first, as is customary, thus leaving the impurities to accumulate in the bottom to be finally fed to the evaporating-pans; but on the contrary the oil is fed always from the bottom of the pans d, which freshens the supply in said evaporatingpans. Each of the pans d is provided with an overflow-pipe f, that projects vertically nearly to the top of said pan and communicates with the next adjacent lower pan.

The capacity of the reservoir may be regulated to feed any desirable number of evaporating-pans, and may contain one or more barrels of oil. The oil is introduced through the pipe g, that communicates with the upper reservoir-pan d, from whence it passes to the upper evaporating-pan b. When the oil in both of these upper pans (Z and Z) reaches a plane coincident with the upper end of the overflow-tube f in the upper pan (1, the oil then passes through said tube to the next lower pan d, from whence it passes to the next adjacent evaporating-pan b, and this operation is repeated until the remaining lower pans d and b are similarly supplied with oil. As the oil in each of the evaporating-pans is consumed, oil passes from the pans (Z in fresh quantities, each pan d supplying its respective pan 1) in the manner stated; By this arrangement of the evaporating-pans it will be seen that a great evaporating surface or area of oil is exposed to the air, and which is obtained within a comparatively-small space, as compared with those carburetors that are For example, a carburetor constructed in accordance with the foregoing description having, say, four evaporating-pans, each of which is thirty inches square, will provide three thousand six hundred inches of evaporating-surface.

7L designates a series of suction pipes, which communicate, respectively, with each of the pans (Z and serve to cleanse said pans whenever necessary.

The air is introduced to the bottom evaporating-pan Z) in a well-known manner through a pipe 3 and passes upwardly and is carbureted by coming in contact With the hydrocarbon oil. The carbureted air is emitted through a pipe 8.

In practice it is desirable to extend the pans Z) and (1 higher than shown in the drawingsthat is, about one and a half times as high as shown-and to correspondingly lengthen the overflow-tubes f.

I am aware that it is not new to supply a plurality of tanks or pans with liquid by means of overflow-pipes leading from one to the other. Therefore I do not desire to make claim thereto; but my invention consists of providing means for uniformly supplying a number of stationary evaporating pans with oil, said pans occupying a minimum amount of space and aifording a maximum amount of evaporatingsurface, and in which the use of floats and valves is dispensed with.

I claim 1 1. In a carburetor, the combination of a stationary carburetor consisting of a plurality of communicating evaporating pans arranged one above the other, a reservoir of a corresponding size to said carburetor and consisting of a similar number of communicating pans each of which is on a plane with one of said evaporating pans, a tube connecting each of said reservoir pans with its adjacent evapcrating pan, said tube occupying a position adjacent to the bottom of said pans, substantially as and for the purposes specified.

2. In a carburetor, the combination with a plurality of evaporating pans placed one above the other, of a reservoir adjacent to said evaporating pans and consisting of a plurality of pans of a size and form corresponding to said evaporating pans and placed on a horizontal plane therewith, a communicating tube between each of said evaporating and reservoir pans, an overflow tube between each of the reservoir pans, by means of which said evaporating pans are uniformly fed with oil from the bottom of the reservoir pans, substantially as described.

In testimony whereof I have hereunto set my hand this 10th day of May, 1895.
