GAS-MANUFACTURING APPARATUS- Specification of Letters Patent.

katented April 2, 1907.

Application filed May 26,1906. Serial No. 318,825.

To all whom, it may concern:

Be it known that I, JACOB J. BUsENBENZ, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gas-Manufacturing Apparatus, of which the following is a specification. My invention relates particularly to the manufacture of gas from volatile liquids, filich as the hydrocarbon oils, alcohol, or the My primary object is to provide improved apparatus for manufacturing and storing for current use a substantially fixed gas, dispensing with the use of heat in the generation of the vapor entering into the gas mixture, and providing for automatic operation of the apparatus and the formation of the mixture under such conditions as to insure always the proportions requisite to a fixed gas. In theoperation of the apparatus shown a volatile liquid, such as gasolene, and air are injected under corresponding pressures in atomizing relation into a mixenchamber in the absence of heat, and air from the external atmosphere is drawn therewith into the mixer-chamber in suflioient quantity to form the proper admixture of air and vapor to form a fixed gas. The admission of the air under pressure, the oil under pressure, and the air drawn under suction from the atmosphere is automatically controlled by the movable member of a gas-holder, said gas-holder being in communication with the mixer-chamber. The source of oil-supply is an oil-tank, in which the oil is displaced by water from a water-tank under the same pneumatic pressure as that of the air, serving as an atomizing agent at the mixer-chamber. The preferred construction is illustrated in the accompanying drawings, in which Figure 1 represents a plan view of gas apparatus constructed in accordance with my invention and operating upon the principle above described, a portion only of the gasholder being shown; Fig. 2, a broken side elevational view showing the construction at the injection ends of the mixer-chambers, of which three are shown Fig. 3, a broken vertical sectional view of the portion of the apparatus shown in Fig. Fig. 4, a View taken as indicated at line 4 of Figs. 1 and 2 and showing in elevation an air-pipe through which air is introduced from the external atmosphere Fig. 5, a broken side elevational view taken as indicated at line 5 of Fig. 1; and Fig. 6, a plan sectional view taken as indicated at line 6 of Fig. 5, said view showing the details of the valves controlling the air admitted to the injectors and to the hydraulic tank or water-tank.

In the construction illustrated, A represents a plurality of superposed mixer-chambers, A, a series of injectors having oil-supply pipes A receiving their supply from a common pipe A, and having compressed-air pipes A receiving their supply from a common stand-pipe A, which in turn is supplied from a compressed-air pipe A; A a series of air-conduits receiving their supply through a common stand-pipe A; B, an automatically-operated valve controlling the oil admission through the pipe A; B B, Fig. 5, a pair of automatically-actuated valves controlling the passage of the compressed air through the pipe A; B, an automaticallyactuated valve controlling the admission of air from the external atmosphere to the stand-pipe A; B an automatically-actuated rock-shaft controlled by the gasometer and equipped with a plurality of arms B, connected by links B with the actuating-arms on the stems of the valves mentioned; C, an oil-tank serving as a source of supply for the oil-pipe A and having a pipe C, through which oil may be introduced, and a pipe C through which water under pressure may be supplied D, a combination hydraulic and pneumatic tank with which the pipe C is in communication and which receives its watersupply through a pipe D and its air-pressure through a pipe D which connects with the pipe A between the valves B B E, a tank containing air under high pressure, from which the pipe A receives its supply through a reducing-valve E of common construction F, a gas-holder receiving its supply from the Inixer-chambers through a pipe F, and F means controlled by the movable member of the gasholder for actuating the rock-shaft B in one direction to close the valves B, B, B and B when the holder is filled with gas and to open said valves when the gas-supply is nearing exhaustion.

The mixer-chambers A may be of any suitable construction. They are shown as comprising-cylindrical tanks located one above the other. The injectors A are located one above the other and connected with the adjacent ends of the tanks A. Each injector is located partially within a chamber a, connected with the tank end and forming a portion of the conduit A A tube a, located within the chamber a, is equipped with a gate-valve a having a stem projecting through a lateral wall of the chamber a and equipped with a hand-wheel of, by means of which the valve may be manually opened or closed. One end of the tube a opens into the mixer-tank, and the other end thereof terminates near the opposite end of the cham ber a, and has entered therein a nozzle of. Adjacent to the point of the nozzle the tube a is provided with air-inlets a. The nozzle has a central passage a for oil, and this passage is in communication with the corre sponding oil-pipe A The nozzle also has an annular channel a surrounding the oil-channel, and with said annular channel communicates the corresponding air-pressure pipe A The annular channel converges at the point of the nozzle, so that the compressed air and the oil under pressure enter the tube a in atomizing or vaporizing relation, and the external atmosphere is entrained at the point of the nozzle. The chambers a are equipped with drain-pipes a which communicate with a common drain-pipe a. Each of the oiladmission tubes A is equipped with a manually-operated valve a The connection of the oil-supply pipe A with the branch supply-pipes A is through a stand-pipe a, as shown in Figs. 2 and 4. It will be understood that the stand-pipe A and the stand-pipe A have dead ends at their lower ends.

The valve B is similar in construction to the valves B B (Shown in detail in Fig. 6.) Each of the valves B B B comprises a disk I), working on a seat 6 within a casing 6 and a stem b equipped with an arm I). In the case of the valve B the arm 11 is connected directly with one of the rods B, actuated by the rockshaft B. In the case of the valves B B the arms 5 are connected, as shown in Fig. 5, by a link if to the corresponding connecting-rod B. Thus one connecting-rod serves to actuate both of the valves B B The construction of the valve B will be understood from Fig. 3. The casing 1) constitutes an intake for the pipe A and has an upturned orifice b guarded by a screen. The valve-seat is designated Z2 and comprises a disk adjacent to whose inner surface is located a disk valve b, held firmly upon its seat by a spring b The stem 1) of the valve eXtends through the disk 6 and through the outer end of the chamber 1) and is equipped with an arm I)", connected with the corresponding link B, operated by the rockshaft B The construction of the tanks C and D and their connections need not be described in detail further than to say that the pipes are usually equipped 'with manually-operated valves (not shown) to enable the oil and water to be drawn in and discharged at will.

During the operation of the plant the pipes C and D are of course closed.

The construction of the compressed-air tank E is not essential. The construction of the reducing-valve E need not be described in detail, as any suitable reducing-valve may be employed to allow air to pass from the tank E into the pipe A and assume a working pressure within said pipe of any desired amount.

The construction of the gas-h0lder F may be varied. Any suitable gas-holder having a movable bell or gasometer may be employed. Also the device F for actuating the rock-shaft B may be of any suitable construction. Preferably it is of the construction shown and claimed in my pending application, Serial No. 252,761, filed March 29, 1905, and it is sufficient to say that when the gasometer reaches the upper end of its movement the device F operates to turn the rockshaft B in a direction to close the valves B, B, B and B and when the gasometer reaches the lower end of its traverse the de vice F operates to turn the rock-shaft B in the opposite direction and open said valves.

The operation may be briefly summarized. The tank E is kept filled with air under a high pressure, being supplied from any suitable source. (Not shown.) Air from the tank E passes the reducingvalve E into the pipe A and maintains within said pipe a suitable working pressure. Assuming the valves B B to be open, the air-pressure from the pipe A is admitted through the pipe D to the hydraulic tank D, displacing the water in said tank and forcing it gradually into the tank C, where the water displaces the oil, forcing it through the pipe A to the injectors, it being assumed that the manually-op erated valves a are open and the automatically-actuated valve B is open. Pressure from the pipe A is also admitted into the stand-pipe A from which currents of compressed air pass through the annular passages of the injectors, meeting the streams of oil passing therethrough from the tank 0 and atomizing the oil. The injectors operate to ICO draw in air through the conduits A which are supplied from the stand-pipe A it being understood that the valve B is open during the process of manufacturing the gas. The oil and air passages through the injectors and the air-inlet passages of, through which atmospheric air is admitted, bear such rela meet the needs at the time of installation,

using only one of the injectors, thus providing for increased capacity as necessity may require.

In the practical operation of a plant of the construction illustrated it has been found that the apparatus will work automatically with the greatest certainty and regularity and that little attention on the part of an attendant is required.

The injector herein shown is illustrated and described in detail and fully claimed in my application, Serial N 0. 318,826, of even date herewith.

It is to be understood that the foregoing detailed description has been given for clearness of understanding only and that no undue limitation of the invention is intended thereby.
