JAMES VINANTS TALLMADGE, OF ALBANY, ASSIGNOR TO THE ELECTRIC GAS MACHINE COMPANY, OF CASTLETON, NEV YORK. i

APPARATUS FOR THE MANUFACTURE OF HYDROGEN GAS.

SPECIFICATION forming part of Letters Patent No. 452,246, dated May 12, 1891.

Application iiled August 30, 1890. Serial No. 363,480. (Model.)

T0 all whom, it may concern:

13e it known that I, JAMES WINANTs TALL- MADGE, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Apparatus for the Manufacture of Hydrogen Gas, of which the following is a specification.

This invention rela-tes to an apparatus for the production of carbureted hydrogen gas in which the hydrocarbon liquid is iioated on the acid solution, said apparatus being especially adapted for the illumination of buildings from isolated plants.

The objects of the invention are to provide a portable gas apparatus of thisvcharacter of comparatively large capacity, which can be readily passed through a door or window to be placed in the cellar or other convenient location within the building to be illuminated; to provide convenient means for recharging the apparatus with the metal to be consumed in the production of the hydrogen gas without permitting the escape of the gas; to provide a safety-valve which will prevent the hydrocarbon liquid from being forced out of the generating-compartment when the lights are shut off, and to provide convenient means for charging the hydrocarbon liquid into the apparatus wit-hout the escape of gas therefrom.

Figure 1 of the accompanying drawings represents a vertical section of a building and a longitudinal vertical section of this improved gas apparatus disposed in the cellar thereof, the pipes leading from said apparatus to the gas-ixtures being shown on an enlarged scale. Fig. 2 represents a transverse section on line 2 2 of Fig. 1 of this improved gas apparatus. Fig. 3 represents a longitudinal section of the tank, the metal tray and its supporting mechanism being shown in working position in full lines and in open position in dotted lines. Fig. fl represents a vertical section, on an enlarged scale, of the safety-valve. Fig. 5 represent-s a vert-ical section, on an enlarged scale,

of the iillingdevice for the hydrocarbon liquid.

Similar numerals of reference indicate corresponding parts in the different figures.

The tank 10, constituting a part of this :im-

proved gas apparatus, may be disposed in the cellar or basementof a building to be illuminated, or at any other convenient point adjacent thereto. This tank is elongated horizontally to enable it to hold a large quantity of acid liquor, and is preferably of such width and height as to enable it to be passed through an ordinary Window or door. It is preferably made of wood and provided with an interior lining 11 of lead or other suitable material, or the tank may be made of vitriiied pottery orother suitable material. Standards or lugs 12 are disposed on opposite sides of the tank and project slightly above its top. The upper part of the tank is divided into a generating-coinpartment 13 and a reservoircompartment 14E. The generating-compartment 13 extends downward from the top of the tank and terminates above the bottom thereof, being open at its lower end into the tank. This generati11g-compartment is also lprovided With a suitable lining 15, and it is preferably attached to the cover 1G of the tank, said cover constituting the top of said compartment. Instead of being so attached, the generatingcompartment may be formed by a transverse partit-ion 17, extending down- Ward from the top of the tank toward the bottom thereof, as illustrated in Fig. 3.

A perforated tray 2O or its equivalent for containing metal scraps to be consumed by the acid for producing hydrogen gas is supported Within the generating-compartment 13 upon movable supports, by which it may be withdrawn through the open bottom of the generating-coinpartment and through the reservoir-compartinent without the escape of gas from the generating-compartment when the metal needs to be replenished; The movable supports, as shown, comprise curved arms 21, attached to dependent arms 22. These arms 22 are connected with levers 23, pivoted at 24 to the lugs or standards 12, attached to the center of the tank at opposite sides thereof. These arms are preferably connected by the cover-plate 25, which serves to cover aportion of the reservoir-compartment, the remaining portion of said compartment being closed by a fixed cover 26. The cover 25 has a weight 27 on its under side to counterbalance the metal in the tray. The tray 2O is pivoted at 28 to the upper ends of the curved arms 21,

whereby it maintains a horizontal position during the movement of its supports.

A iilling device for supplyingasuitable hydrocarbon is disposed in the top of the gascompartment,and comprisesatube3l,extend ing above the top of said compartment, anda pipe-trap depending below said top and consisting of a U -shaped pipe 32, having one end elongated to extend through the cover. The io tube 31 preferably extends through the wall to the outside of thebuilding` and is closed by a cap 83.

A safetyvalve is disposed in connection with the generating-compartment- 13 to pre- I 5 vent the hydrocarbon liquid from being forced out of the generatiiig-compartment. This safety-valve comprises a dependent tube Al1, extending downward through the top of the gas-gcnerating compartment, and a iloat 4Q, zo having a hollow stem 1S adapted to slide vertically on said dependent tube. The hole in the stem 43 is of larger diameter than the dependent tube l1 to permit the gas to pass through said stem around said tube. The lower end of the hollow stem is closed and a small quantity of mercury ll is disposed therein, which forms a liquid seal for closing said tube. The tloat l2 is of such gravity as to tioat uponthe acid solution, but not upon the hydrocarbon liquid. 'lhe dependent tube is provided above the top of thegeneratingeompartment with an escape-pipe 45, which passes throughthe wall of the building, and is provided with a downturned outlet 4() outside said wall. This escape-pipe is preferably provided with an offset 17 to prevcntthe mercury from being blown out with the gas.

A gas-eduction pipe leads from the top of the generating-eompartment and connects 4o with the service-pipes extending to the different parts of the building to be supplied with gas, said pipe beingpreferably provided with a stop-cock 51 nearthe top of the generatingcompartment.

In the use of this apparatus the tank 10 is placed in the desired position and the proper pipe connections, as hcreinbefore referred to, are made. rllhe tank is then partially filled with a suitable acid liquor GO, such as a di- 50 lute sulphuric-acid solution, said liquor being suliieient in quantity to risc above the open lower end of the gencrating-compartment 13 and above the bottom of the metal tray 2() when normally disposed therein. A 5 5 quantity of a suitable hydrocarbon liquid 70 is then fed into the gcnerating-compartment 13 through the feed-pipe 31 and floats upon thesurfacc of the acidliquor within the generating-compartinent. After the desired quan- (io tit-y of hydrocarbon is fed through the tube 31 a small quantity of the acid liquor is fed `into the feed-pipe, and this liquor pushes out the hydrocarbon remaining in the

pipes

31 and 32 and forms a trap or water seal in the bend of said pipe and prevents evaporation Vof hydrocarbon from said pipe andthe entrance of gas thereinto. 'lhus the odor of hydrocarbon about the apliaratus is avoided. 'lhe levers 23 are then swung into positions the reverse of normal, as indicated in dotted lines in Fig. 23, whereby the metal tray 20 is withdrawn downward from the generatingcom partment 13 and upward through thereservoir-eompartment la and suspended in convenient position for the placing of the metal scraps thereon. The required quantity of scrap-iron SO or other suitable metal scrap is then placed upon the tray and said tray swung into the tank and into normal position in the generati11g-compartment 13 thereof, as shown in Fig. l. In this position the metal scrap SO is submerged or partially submerged in the acid liquor GO. The acid attacks the metal and hydrogen gas is generated, which rises through the layer of the hydrocarbon liquid floating on said solution within the gcnerati11g-compartment and becomes impregnated with hydrocarbon vapor. The carbureted hydrogen thus formed accumulates in the generating-compartment and passes out through thc eduction-pipc 50 for supplying the burners connected with the gas apparatus. lVhen the burners are shut off, gas accumulates in the generating-compartment and the pressure thereof forces down theliquid in said compartment until the acid liquor falls below the tray and thehydrocarbon submerges the metal therein. The formation of gas then ceases. It sufficient acid remainsin the metal to continue the generation of gas after the burners are sluit olf to suoli an extent as would cause the level of the acid solution to fall below the open lower end of the generating-compartment 13 and permit the hydrocarbon to escape into the reservoircompartment 14, the safety-valve 40 will permit the gas to blow off before the hydrocarbon can escape. 'lhc lloat 42 of said valve in such case descends until the mercury 4l within the hollow spindle 43 falls below the lower end of the dependent tube 4l, whereby the gas is permitted to escape downward through said hollow spindle, upward through said tube, and out through the escape-pipe 45 to the outside atmosphere. As undue pressure is removed, the level of the acid liquor within the generating-compartment rises, carrying the floatvalve upward, causing the mercury seal to close the lower end of the tube. A proper level of acid liquor is thus maintained in the generating-compartment and escape of the hydrocarbon prevented.
