TO ALL WIIOM IT MAY CONOERN:

Be it known thatLJAMus T. SPnNcE, of Brooklyn, in the county of Kings, and State of New York, have invented a new and improved Hydrocarbon Vapor Machine, and 'that thc following description, taken in connection with the accompanying drawings hereinafter referred to, forms afull and exact specitication'of the same, wherein I have set forthvthe nature and principles of my said improvements, by which-my invention may he distinguished -frein all others of'a similar class, together lwith such parts as I claim and desire to have secured to `me-b'y Letters Patent'.

This invention relates to :rnew and improved machine or apparatus for vaporizing volatile hydrocarbons ior illuminating purposes, and consists in a ndvel and improved means for creating a draught of `atmospheric -air through the chambers containing 'the material to be vaporized, such for instance as the light grades' of coal oil, naphtha, gasoline, etc., ete., and also in improved valves for checking the draught whenever the apparatus ceases its operation.` 4The invention finally consists in the use of a combination of-heavy hydrocarbons, or those which vaporize at 'quite a high temperature, with that o't` a lighter grade, whereby all danger of explosion is avoided.

The invention hasfor its object the production of a steady light, a large yaporizing surface within` a limited space, and'safety from explosion in usingthe apparatus. In thc accompanying sheet of dmwingsV Figure 1 is a transverse vertical section of my invention, taken in the line :e x, iig. 2.

Figure 2, a front `view of thelsame, `partly in section.

Figure 3, a detached end view of one of thc revolving chambered drums pertaining to the same.

Figure 4, a front view of one ofsaid drums, partly in section.

Similar letters ofreference indicate like parts.

A represents a rectangular box, which is divided into two compartments B C, by a partition, a, and supported at a proper height by feet Iz. Each of these compartments is supplied with the naphthaor other duid to be vaporized, andv designated by c, -and this fluid is supplied to the compartments B C, through pipes d d, leading from a reservoir, D, on the t`op of an upper chamber, E. The lower compartmenti has two pipes e e, comm'unieating with its upper part, and to the lower ends of these pipes chambers f are attached, cach containing a valve, g, constructed out of some light material, such as cork, for instance. The lower compartment B communicates with the upper one C, by means of a series of small pipes h, and the upperV compartment C communicates by u.`

pipe, ax, with a receptacle, F, at one side` of the upper chamber E, an opening being made in the outer or face sideof said chamber, which is closed by a screw, z', or other means. In the upper chamber E there is pissed centrally and longitudinally a shaft, j, which is rotated by gearing lc from a driving-shaft, G, and has upon it two drums H I-I, divided into four compartments l, by oblique' partitions m, (see iig. 4.). Each chamber has a radial opening, n, at one end of it, arid a tulle, c, communicates with each chamber and extendsl aroundthe periphery of the drums in a backward direction a distance equal to about one quarter of their circumference, {see fig. 3.) The sides of the drums H, opposite to the sides where the, openings n are made, have concentric openings p to receive each a pipe, q, from the receptacle F, the ends ot. the pipes g turning upward above the surface of the liquid in chamber E, (see iig. l.) Th'c chamber E is supplied with a light grade of. fluid, such as naphtua, gasoline, etc., from a reservoir, D', in the chamber E, a pipe 'r, conducting the same from D into E, (see iig. 2.) I represents gas iets, which are within annulaichnmbers s, which communicate with. chamber E, and are supplied with gas from the chamber E:

The operation is as follows: The upper chamber E is supplied with the light material, naphtha, gasoline, or other similar substance, designated by t, and also supplied with heavier substances, such as whale oil -u,.and

lard-oil o. These heavier hydrocarbons servo as adulterates, and prevent artoo great `vaporization of the liquid in E, aiulcorfsequently prevent-a liability to explosion. The drums II, as they rotate, serve to create a suction through the chambersl B, C, and E, as indicated by the arrows, nnd the tubes o admit of the air in the chambers l being gradually expelled :is the openings n of .the chambers pass through the duid in E, the mingled vapor and air passing gradually out from the ends of the tubes o, and prevent-ing thosudden puits or .vibrations which would otherwise occur when the openings c pass out from the iiuidat, the rising sides of the drums, it being understood theft the openings p, at one side ofthe drums, arcfbelow the surface of the iluid in E. The air that enters the drums 1I through the openings fn., when the latter are above the iiuidin E, isl mingled with the vapor as the openings become submerged in the Huid, and eiective and even vaporization of' the fluid is `therefore effected. Thi,- draught caused by the rotation of the drums causes a good draught through all the chambers. The gas jets I are kept burning in case the iluid in E requires any warmth. The tubes o are a great acquisition, causing a steadj)vr light, it being understood that the chamber E is the main or holderwith which the pipes on which the gas-burners are placed communicate. The light valves g chock the draught instantly as soon as the rotation of the drums H ceases.l Their extreme lightness admits of them readily rising under a light draught while 'the valves will close or drop instantly, as soon as the draught is stopped. These .valves Ythereby prevent any escape of vapor when the device is inoperative.` I

Having thus described my invention, I claim as new, and desire to secure by Letterslatent- 1. Thevcombination'and arrangement of the three chambers B C4 E, with the reservoirs D D and supply v pipes d d r, substantially as and for the purpose set lforth.

2. The two rotating drums H, provided with chambers L, in combina-tion with the tubes o, substantially as I and for the pur-pose specified.

3. In a hydrocarbon vapor machine, the employment or nseof Ia plurality of hydrocarbonsof different grades, placed in one or more chambers of the machine, substantiallyv 'as and for the purpose set forth. O

4. The valvesf, constructed of cork, or other similar light material, when used in connectimi with a hydrocarbonvapor machine, substantially as and for the purpose set forth. u Y l 'I JAMES F. SPENCE.
