CARBURETER.

To allwhom it may concern:

Beit known that I, WILLIAM SHEARER, a

subject of the King of Great Britain and Ireland,yresiding at Ferniecotf 3 Abbey road,`v,-FJskbank, in the county of Mid-Lothian, V.Scot-land, have invented new and useful 'Improvements in Carbureters, of which the following is a specification.

v My said invention has for its object to improve the construction and action of carbureters employed in plants making hydrocarbon, petrolized, or air gas in which air is mixed with a hydrocarbon such as gasolene, petrol, and the like, `and then utilized as a gas for illuminating, heating, and like pur poses.

In carrying out my invention the vapo- `rizing surface of the carbureter is arranged so that the hydrocarbon will spread quickly and evenly over a large area, thus completely evaporating the hydrocarbon, and at the same time distributing the reduction in temperature (due to evaporation) over a large surface. To the reverse or underside of the evaporating surface a number of and are immersed in the water or other medium usually employed to retain the carbureter at a suitable temperature, and by means of those vanes a uniform, or nearly uniform, temperature of the evaporating surface is obtained.`

Means are provided to protect the incoming hydrocarbon, from the air, until such 'y time as it spreads in a thin film over a por tion of the evaporating surface. Means are also provided to distribute the air to the evaporating surface and at the same time to ive it a swirling motion so as to insure a iorough mixing of the gas or vapor.

In order that my said invention and the manner of performing the same may be properly understood I hereunto append a sheet of explanatory drawings to be hereinafter referred to in describin my invention.

Figure 1, is a sectional evation of one example of my invention, and Figs. 2 and 3, are horizontal sections on the lines awt, and C d, respectively, of Fig. l. Fig. 4, is a. sectional elevation of another example, while Figs. 5 and 6, are horizontal sections taken `on the lines e-f, and g-L, respectively, of Fig. 4.

In these drawings the same reference letters are used to mark the same or like parts wherever they are repeated.

As shown in Fig. 1 of the drawings the carbureter consists'of the usual cylinder or casing, A, within which is arranged a second casing B, the upper' external surface, C, of which is made spherical, .oval or dome shaped, so as to present as great an evaporating surface for the hydrocarbon as is practically possible. The casing B, has arranged within it a series of vanes D, the ob ject of which is to .maintain or equalize the temperature of the evaporating surface, C. The hydrocarbon enters the cylinder or casing A, by the pipe, E, to the evaporating surface, C, and a ca o or disk F, protects the hydrocarbon from t e action of the air until such time as the former has spread in a thin film over a considerable portion of the evaporating surface. The air enters by the port, M, and passes through a number of passages, Gr. These passages may be arranged so as to pass the air in one or more directions. As shown in the drawings these oassages are of substantially rectangular form and have wings projecting downwardly therefrom at an inclination, said wings tapering from the inner ends of the passages to the outer ends. The gas or vapor before reaching the outlet or discharge pipe, H, is intercepted by a number of baffle plates J, so that it is thoroughly mixed before passing from the carbureter. The cylinder or casing A, of the carbureter is supported on feet, K, to allow of adequate circulation of the water or other anti-freezing mixture.

As shown in Fig. 4, three casings, B, in the form of spheres, or balls, are employed. These casings, B, are provided with passages, L, so that when the carbureter is placed in a tank or vessel containing the anti-freezing mixture free circulation takes place.

The pipes L (Figs. l and 4) communicate direct with the interior of the inner casing. When the carbureter is placed in a tank containing water, the vaporization of the petrol lowers the temperature of the vaporizing surface C, transmits the cold to the 'vanes D, and as these vanes are immersed enters by the pipe, E, and spreads in a thin mixes with the air which enters by the port,-

M, and passages G, and is rapidly vaporized. On reaching the baillev plates J, the

gas or Vapor is subJected to a final mixing, afterward passing to the discharge pipe, H.

vWhat I claim as my invention is:

l. A carbureter comprising an outer casing, an inner casing mounted therein and provided with a dome-shaped upper end, means for introducing air to the space between the two casings, and for taking the carbureted air therefrom, means for delivering hydro-carbon to the upper surface of the dome-shaped upper end, and means for circulating a heating` medium through the inner casing.

2. A carbureter comprising an outer casing, an inner casing mounted therein and provided With a dome-shaped upper end, means for introducing air to the space between the two Casin s, and for taking the carbureted air there rom, means for delivering hydro-carbon to the dome-shaped upper end, and passages leading from the outer to the inner casing, said inner casing having an opening in its bottom.

3. A carbureter comprising an outer casing, an inner easing mounted therein provided With a dome-shaped upper end, means for introducing air to the space between the casings and for taking the carbureted air therefrom, vanes secured to the inside of the inner casing, means for delivering hydrocarbon to the dome-shaped upper end, and means for circulating a heating medium through the inner casing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. l
