IMPROVEMENT IN THE PROCESS OF MANUFACTURING ILLUMlNATlNG-GAS- Specification forming part of Letters Patent No. 34,185, dated January 14, 1862.

To all whom it may concern.-

Be it known that we, ALLEN WALTON and JOHN L. KITE, both of the city of Philadelphia, State of Pennsylvania, have invented a new and Improved Coal-Oil-Gas Apparatus; and We do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Our invention consists in injecting a steady and continuous stream of air into a retort in which gas is generated from coal-oil or its equivalent, substantially as described hereinafter, so as to deprive the gas of its superflu-ity of carbon and other impurities and render it more fit for illuminating purposes.

In order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure 1 is an end view of our improved coalo lgas apparatus; Fig. 2, a ground plan; Fig. 3, a rear view of the apparatus, and Fig. 4 a detached view of the retort.

Similarletters refer to similar parts throughout the several views.

A is a cast-iron casing, made in the form of an ordinary stove, and furnished With a firedoor a and ash-pit b, above which is a suitable grate for supporting the fuel.

B is the retort, which is composed of the horizontal pipe 0 and vertical pipe d, as represented in Fig. 4, the horizontal portion of the retort passing through and projecting at each end from the casing A, and the vertical portion passing through the top of the casing.

C is the gas-holder, consisting of a tank containin g water and an inverted hollow cylinder, which is weighted and otherwise arranged in a manner too well known to need description. A pipe D aifords a communication between the interior of the gas-holder and the vertical portion d of the retort.

E is an air-vessel consisting, as with the gas-holder, of a Water-tank with an inverted hollow cylinder, the latter being Weighted, so

that a steady and continuous stream of air may be forced through the pipe F into the rear of the horizontal portion a of the retort. To the front of the latter is connected the siphon-formed tube G, which has at its upper end a funnel-shaped mouth for receiving the coal-oil or other equivalent material from which the gas has to be generated.

Gas generated from coal-oil is possessed of such an intimate admixture of carbon that it cannot in its crude state he used for illuminating purposes, as the light is deficient in brilliancy, and a smoke more or less dense accompanies the flame. By introducing a steady and uniform stream of air into the retort, so that it may become intimately mixed with the gas, not only is the latter purified and deprived of the greater portion of its carbon, but the flame is rendered more brilliant and is free from smoke, which in the absence of a plentiful supply of air must prove a source of annoyance, owing to its deleterious effects, as Well as its uncleanliness.

It Will be evident that, although we have heretofore alluded to coal-oil as the material from which gas has to be generated in connection with our improvements, the latter are equally applicable to gas apparatus in which rosin and other equivalent substances are used.

We do not desire to claim, broadly, the admixture of atmospheric air with illuminatinggas previous to its issuing from the burner; but

IVe claim as our invention and desire to secure by Letters Patent Injecting a steady and continuous stream of air into a retort in which gas is generated from coal-oil or its equivalent, as and for the purpose herein set forth.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
