TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN S. HULL, of Cincinnati, in the county of Hamilton, and State of Ohio, have invented a new and useful improvement in Gas-Generating Apparatus for generating gas from hydrocarbon oils; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, made part of this specification, in which- Figure 1 is a perspective view.

Figure 2 is a side elevation.

Figure 3,-a vertical section on the line a: m, fig. 2; and

Figure 4 a similar sect-ion on the line 3 3 fig. 2.

The same letters throughout refer to identical parts. p

A is the induction tube through which the oil is carried from a reservoir andadmitted into the chamber B. On entering the chamber the tube is bifurcated, and the oil carried upwards through the tubes indicated in red lines in fig. 1, and marked C and C, through the lips I I, which, being in direct contact with the'fiamc, are heated to avery high degree. The oil is here vaporized, and the gas passes downwards with the continuation of the same tubes into the receiving'chamber D. This chnmberis'formed in the boss L, which is placed upon the stem B of the chamber B. The boss maybe attached either by a screw, as shown, or by soldering. From the receiving-chamber D the gas passesthrough an opening, D, into the internal chamber formed in centre of the stem 13".. Aneedle-pointed valve, E, passes by a screw, forming an air-tight joint, through the stem B, and while it prevents the escape of gas downwards it'regulates perfectly the flow of gas-upwards into the internal chamber G, from which it passes through the narrow opening I'I between the lips I I. An opening, B admits the atmosphere to the flame, which burns above the opening H and between tho lips I I, extending at the same time above them. At M there is an opening through the walls of the chamberinto the tubular chamber G for the purpose of aeratin the gas fiowing from the receiving-chamber D. The quantity of atmospheric air required depends upon the character of the oil and the purpose for whichthe combustion is desired. If heavy oil is used more air is required than when the thin or light oils, such as benzinc, &c., are used. So, also, if the combustion is designed for the purpose of generating heat, air is required to be mingled with the gas, but where the apparatus is employed for purposes of illumination no air should be admitted below, the effect of the admixture of' air being to make a blue flame of great heat. To adjust the quantity of air according to these various requirements I employ an adjustable collar, K', working upon a thread cut on the surface of the boss L. Thiscollar fits snugly to the chamber B, and as it is turned up or down regulates the flow of air through the opening M, over which it may he carried entirely. As will appear from the foregoing descrip-.

tion this apparatus may be used for purposes of heating as well as illumination.

What I claim as my invention, and seek to secure by Letters Patent, is

1, The chamber Bof a gas generator when constructed with lips I I projecting above the point of ignition and in immediate contact with the flame, the oil being conducted through them in tubes C and C, substantially as set forth.

2; In combination with the opening M, through the chamber B, connecting with the internal chamber G, I

claim the adjustable collauK for regulating the supply of atmospheric air, substantially as and for the purpose set forth,

3. I- claim the chamber 13 when constructed with pipes C C, lips I and I, and openings B and M, arranged substantially as and for'the' purpose set forth.

4. I claim the receiving-chamber D, formed in the boss L, with its induction and eduction openings when. theflow'of gas through the same is regulated by a valve, E, substantiallyas set forth. i

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

JOHN S. HULL.
