To all whom, it may concern? Be itknown that I, Amos PEIRCE CHAM- BERLAIN, a citizen of the United States, at

j exact terms as to enable any one skilled in the arts to which it appertains or with-which it is most nearly connected to make and use the same, reference being had to the accompanying drawings, making part of this specification, and to the figures and letters of reference marked thereon, and in which- Figure 1 is a longitudinal sectional elevation of asuitable form of retort to be used in the practice of my invention, together with a wetterreservoir and gas-receiver. Fig. 2 is a transverse section of Fig. 1, showing only the parts that appear by cutting the section. Fig. 3 is a longitudinal section of a retort of circular form havinga return-flue through its center for the passage of the heat, instead of over the top, as in Fig. 1. Fig. 4 is a transverse section of the retort shown by Fig. 3. Fig. 5 is a longitudinal vertical section through the retort and an air-forcing apparatus, B.

My invention relates to the manufacture of rich fixed gas for illuminating and heating purposes; and it consists of making such gas of hydrocarbon oil, water, and atmospheric air by intermingling themin a retort heated high enough to decompose them, and of then passing the resultant gas directly from the retort, in its highly-heated condition, through a water bath. V

The invention may be carried into efiect by any suitable apparatus. The one I have represented by the drawings is well adapted for the purpose; but others may be devised that will accomplish the same result without departing from the principle of theinvention.

The apparatus illustrated by the drawings consists of one or more retorts, c, inclosed in a brick chamber, and having a flue under, behind, and above it, as shown by Fig. 1. The

furnace for heating the retort is made in the bot-tom flue, as indicated, and the top flue is oil together aredelivered into the retort in charged with coal or coke placed upon the top of the retort, leaving room enough, neverthe less, for the passage of the air necessary for the draft of the furnace. The fire is kindled in the furnace under the retort and passes back around its rear end, returning through 5 5 the top flue upon the coal or coke, igniting it, and making a hot, live fire on the top as well as under the bottom of the retort. In combination with said retortare arranged two reservoirs, a and I), one to contain oil and the other to contain water, and each of them to be fitted with suitable cocks or valves to reg .ulate the flow of oil and water. In combination witheach of these reservoirs is a branch pipe, each of whichis provided with a funnelshaped top, into which the oil and water are delivered from the reservoirs. These branch pipes unite in a pipe, (1, which is common to them both, and into which the oil and water flow and intermix on their way to the retort.

In the front end of the retort an air-pipe, h, is fitted, which pipe is connected to any suitable air-forcing apparatus, B, and should be fitted with a suitable cock or valve to regulate the supply of air.

In the rear end of the retort a gas-deliver ing pipe, 0, is fitted, by which the hot gas, as fast as it is generated by the decomposition of the oil, water, and air, is carried from the retort to the water-reservoir J, and from thence it passes through the water into the gas-holdor K.

The operation of the apparatus is as follows: The oil and water are led from the sepa rate reservoirs, in certain fixed proportions,

through the branch pipes to the pipe (2, common to both reservoirs, the oil mingling with the water as it enters from the branch pipe into the pipe d. From this pipe the water and the form of a spray, caused by the heat of the 9 pipe at, which is carried well into the retort, I as illustrated by the drawings. As the oil and water are delivered into the retort, there is also delivered into it a stream or blast of 5 air from the air-forcing apparatus B through the pipe h, the air mixing with the gas of the oil and water as fast as it is generated, the

monly known as a Root blower, an outline of which is shown by B.

\Vithout departing from the spirit of the invention, the air may be heated in a separate to retort and 'miXed with the oil and water gas after it leaves the retort c and before it enters the water-reservoir; or the air may be heated in a separated retort and passed separately through the water-reservoir and mixed with the oil and water gas in the gas-holder; or it may be heated and delivered directly into the gas-ho] der without passing it through the wa ter; but I prefer to deliver the air into the re t )it simultaneously with the oil and water, and

pass the whole product through the waterair in the proportion of about three feet of air to one foot of gas made from the above proportions of oil and water; but these prop0rtions may vary greatly, depending upon what the gas is to be used for, the richness of the oil, and various other conditions entering into the manufacture and use of the gas. The best proportions of the several constituents under the various conditions will be quickly ascertained by a little experience on the part of the person in charge of the manufacture of the gas. The gas produced by this method may be used alone or in combination with the ordinary coal-gas, which is greatly improved by the combination.

In concluding this specification I observe that in manufacturing gas upon the plan of my invention the oil and water are to be introduced into the retort in the fluid state, and not in the form of steam or hydrocarbon vapor. The introduction of ablast of steam into the retort with the hydrocarbon oil or vapor I have found to be very objectionable. The gas producedv is inferior, either because the force of the steam carriesthe gas-producing elements out of the retort before complete con- .version or because of some chemical'action or reaction unknown to me; and, moreover, the use of a blast of steam for carrying the oil or hydrocarbon vapor into the retort is old, and is not included in my method or claim of invention; but

' YVhat I claim is- The method substantially herein described of manufacturing gas for illuminating and heating purposes, which method consists of introducing air, water, and hydrocarbon oil into a retort heated high enough to decompose them, and of then passing the resultant gas through water, substantially as described, for the purpose specified.

In witness whereof I have hereunto signed my name in presence of two subscribing witnesses.
