APPARATUS FOR MAKING lLLlJMlNATlNG-GAS FROM HYDROCARBON LIQUID AND WATER.

SPECIFICATION forming part of Letters Patent No. 231,423, dated August 24, 1880.

' Application filed June 1, 1880. (No model.)

To all whom it may concern Be it known that I, EZEKIEL B. HOLMES, of the village of (lanandaigua, in the. county of Ontario and State of New York, have invented a new and useful. I mprovement in Apparatus for Making Illuminating-Gas from Hydrocarbon Liquids and Water; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification.

The liquid used may be petroleum or any other hydrocarbon liquid; but I prefer naphtha of a specific gravity of from 68 to 7 The nature of my invention consists in a pcculiar form of apparatus, and particularly in the novel construct-ion of the steam-jet nozzle in connection with the oil-vapor pipe, for the purpose of introducing into the heated hydrocarbon-oil vapor a jet of superheated steam in such a manner as to cause an agitation and thorough mingling of the oil-vapor with the steam, and thereby better effect chemical decomposition and recomposition of the fluids pipe.

removed so as to show one set of coils.

for the production of a fixed pure illuminating-gas.

For a further description I refer to the accompanying drawings.

Figure 1 represents the perspective of the apparatus with front work removed, so as to expose to view a portion of the coil hereinafter described. Fig. 2 represents the plan, showing the bottom coil, the pipe in which the steam is superheated,- and the point at which superheated steam enters the hydrocarbon- Fig. 3 is a transverse section on line A B. Fig. 4 is a longitudinal section on line 0 D. These four figures represent an apparatus suitable for a building using from one to two hundred ordinary burners.

Fig. 5 is a perspective view of the front of the apparatus as applied to ordinary gas- Works, enough of the bricks in the arch being Fig. 6 is a transverse section on line G H. Fig. 7 is a longitudinal section on line E F. Fig. 8 is perspective of the invention as applied in an ordinary cooking-stove. Fig. 9 is a detail view, in longitudinal section, showing the steam-jet nozzle applied to the vapor-pipe.

For a more particular and minute description I give the following details:

The letter 75 represents the pipe conveying the naphtha from a suitable tank or reservoir to the apparatus; the letter I a delicate valve completely controlling the flow of naphtha into the coil. The letter in represents a section of the pipe nine inches in length, reduced to a caliber of one-fourth inch, and this section is filled with iron wire-cloth, for the purpose of more completely regulating the flow of the hydrocarbon. The letter a is the pipe into which the naphtha is received and in which it is converted into vapor. This pipe has a descent of about one-half inch to the foot, and passes on through the brick-work and is capped at n. This is for the purpose of affording an opportunity to clean the pipe in case of any residuum. At 12 this pipe is united with the coil by a T-coupling.

The letters 0 o 0 o o 0 0 represent the coil of iron pipe in which the'destructive distillation of the hydrocarbon and the decomposition of the water is effected.

The letter 19 represents the pipe through which the gas is conveyed from the coil to the receiver, except that in Figs. 5, 6, and 7 this pipe terminates in the' hydraulic main from which the gas is forced, either by steam-exhaust or dry gas-pump, into the gasometer.

Letter 3 is a steam-pipe. Drip-cock q is used for the purpose of permitting the escape of condensed steam. Valve a is for the purpose of admitting steam through the branch pipe 1' into the naphtha-pipe n, and thence through the coil, for cleansing purposes only, and is not intended to be used except when accumulation is suspected.

The valve t is used for admitting steam through the pipe 8 into the pipe 8, where the steam becomes superheated, and from which it escapes into the naphtha-pipe through an orifice about one thirty-second of an, inch in diameter, drilled through an iron plug, in such direction as to cause a rotary motion in the contents of the pipe 0, thus effecting an intense agitation of the gas and steam and facilitating their perfect union. In works ha"- ing large pipes the number of such inlets is to be increased, but not their size.

The nozzle 8 of the steam'supcrheatin g pipe s enters the curved end of the Vapor-pipe O at an inclination, as shown in Fig. 9, so that its end is directed to the inner wall of the vapor-pipe, whereby the escaping jet of steam is caused to impinge obliquely upon the surface of the pipe and be deflected, causing an agitation of the oil-vapors and a thorough commingling thereof with the steam, and carrying the mixture through the decomposing-coil for the better decomposition and recomposition thereof, for the production of a fixed gas.

The letter 1* represents the smoke-stack, and w the grate, upon which the fire from which the heat is obtained rests.

The same letter is used to represent the same part on all the drawings.

Having thusdescribed my invention, I would state that I do not claim the making of illuminating-gas by the combination of superheated hydrocarbon vapor with superheated steam, nor do I claim the use of iron pipes for that purpose; but

What I claim as my inventiomand desire to secure by Letters Patent, is-

1. The combination of the obliquely-fitted jet-nozzle s" with the oil-vapor pipe 0 within the furnace, whereby the oil-vaporis agitated, intimately mixed with the superheated steam, and carried through the decomposing-coil.

2. In the gas apparatus described, the hydrocarbon-vaporizn g pipe n, coiled in the furnace, and the coiled steam-superheating pipe 8, having a minutejet-nozzle, s, entering the vapor-pipe obliquely, as described, in combination with the decomposing-coil O, substantially as and for the purpose set forth.

3. Theinclined hydrocarbon-vaporizingpipe n, extending through the rear wall of the furnace and provided with a cap, a, in combination with the oil and steam induction pipes m 1', connected with its front end, and the decomposing-coil connected with its rear end and extending upward in the furnace to the gas-eduction pipe, substantially as and for the purpose described.
