APPARATUS FOR GENERATING AND CARBURETING HYDROGEN GAS.

. SPECIFICATION formingpart of Letters Patent No. 282,492, dated August '7, 1883,

. Application filed June Ill, 1883. (No model.)

To all whom it may concern,-

Be it known that I, SAMUEL B. BUSHFIELD, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Apparatus for Generating and Garbureting Hydrogen Gas and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawing, and

to theletters and figures of reference marked thereon, which forms apart of this specifica.

tion.

This invention relates to certain improvements in apparatus for generating and carbureting gas for illuminating purposes; and it hasfor its objects to provide for thoroughly carbureting the gas, so as to produce a steady, uniform, and brilliant light,.and to produce 1 an apparatus which will be simple and inexpensive inconstruction, easy to manipulate, and perfectly autom atic in operation. These objects I attain by the means illustrated in the accompanying drawing, in whi ch'is represented a vertical sectional view of my improved apparatus.

In the said drawing, the letter A indicates the carbureting-chanlber, which consists of a closed vessel of metal or other suitable material, preferably of cylindrical shape. Near the bottom of said vessel is located a horizontal ber, as shown.

packed with some absorbent materialsuch as diaphragm or partition, B, of metal or other suitable material, which is provided with one' or more series of annularly-arran ged apertures, 0, near its edge, for the purpose hereinafter explained. Above said diaphragm or partition is located a metallic dome, D, which sets loosely upon said partition, and whichis provided with a series of openings, E, as indicated, and above said dome, in the carbureting} chamber, is a diaphragm or partition, F, from which extends upward short pipes G into the upper compartment of the carbureting-cham- The .said upperchamber is sponge, excelsior, or the likef0r the purpose hereinafter explained. The top of the chamber is hermetically fastened to it, and is providedwith a service-pipe, H, leading to one the flow of gas may be regulated.

or more burners, one being illustrated in the present instance, each burner being provided with a suitable stop-cock, I, by means of which The said top is also provided with a filling aperture or pipe being bent downward at its upper end, as shown, and its extremity passed below said diaphragm, as indicated, for the purpose here:-

inafter set forth.

The letter R indicatesra cock for withdraw ing the spent carbureting-fluid from the lower compartment of the carbureting-chamber, and S a similar cock for drawing off the spent fluid from the upper compartment. 7

The letter T indicates the generatingchamber, which consists of a vessel of copper, lead,

glass, or other material capable of resisting the action of sulphuric acid. The said vessel is of such size that the carbureting-chamber may be fitted upon its top, as shown. Within said vessel projects downwardly a bell of non-corrosive material, which is connected to the lower end of the tube by a gas-tight joint, the tube communicating freely with its interior. From the said tube depends a wire, U, hooked at its lower end, to which may be attached a perforated copper basket, V, provided with perforations W, for the purpose hereinafter set forth.

The operation of my invention is as follows: The gasgenerating chamber is charged with a solution of sulphuric acid in water to about two-thirds of its height, (more or less,) and the basket filled wit-h scrap zinc or iron and secured to the hooked wire. The carbureting chamber is then charged through the'fillingaperture with hydrocarbon fluid of proper specific gravity. The said fluid first collects 'in the upper compartment until it reaches the generating-chamber, the bell extending down into the acid solution in said chamber. Upon opening one or more burners the pressure in the bell will be relieved, the acid solution will' enter it and come in contact with the zinc or iron scraps. Hydrogen gas will be thereby generated,,which will first force the air up through the carburetor and out of the same, after which the gas will commence to flow through, taking the direction indicated by the arrows. The reaction of the acid upon the zinc will develop a certain amount of heat, which will be carried up by the gas and imparted to the liquid in the lower compartment to assist in its volatilization. The dome com pels the gas to pass to the center of the lower chamber, preventing the gas from carrying up any acid or watery vapor into the upper chamber, which might injure the packing, and distributing the gas into the upper part of the lower chamber in such manner that it will pass uniformly to all of the tubes leading to the upper chamber, so as to .distribute it uniformly throughout the packing. The gas in a thoroughly and uniformly carbureted condition finally passes through the service-pipe to the burner or burners, where it is ignited. By wholly or partially turning off the gas the pressure in the bell is increased to a greater or less extent, exposing more or less zinc to the action of the acid, thus rendering the machine entirely automatic in its action.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

The combination, in an apparatus for the manufacture of illuminating-gas, of the carburetor having a perforated diaphragm near its bottom, a loose perforated dome resting thereon and provided with perforations at its center, an upper diaphragm provided with up right tubes extending into a packing-chamber, with a central bent tube connecting with a generator' and leading to the space below thelower diaphragm, a gage pipe connecting the upper and lower chambers of the carburetor, and an eduction-pipe leading to one or more burners, substantially as specified.

In testimony whereof I affix mysignature in presence of two Witnesses.
