. ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed November 10, 1910. Serial No: 591,610.

To all whom'z't may concern:

Be it known that I, J osnrrr CQRROYER, a citizen of the United States, residing at the .city of Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

My invention relates to improvements in acetylene-generators.

The object of my invention is to provide a generator for the productlon of gas fromcalcium carbid which is simple in.construction and which supplies an even flow of purified for the production of light of intense whiteness.

To said end my invention consists in. the combination and arrangement of parts shown in the accompanying drawing, described in the following specification and claimed in the appended claims.

Referring, to the accompanying drawing, the same shows an elevation of the apparatus partly in section to illustrate certain parts hereinafter described and therein contained.

In the drawing 2 designates a tank which serves as a reservoir for the gas as created, to contain the carbid and to serve as sup ports for certain parts thereto secured.

3 shows the inner wall of the tank the.

upper end of which supports the basket 5 which has a rim engaging said end. The

lower part of the. basket consists of wire mesh (3 so as to permit the descent of the carbid dust, moistureand the escape of gas. The upper ends of the exterior and interior walls of the tank are separated by an annular piece having a projection 16 which penetrates and secures a washer 15. The tank supports a dome 4: serving as a reservoir for water. Centrally penetrating said dome is a valve stem 20 having a threaded portion 19 engaging a threaded aperture in the apex of said dome, and the lower'end of said stem is provided with a point engageable with the valve seat 22 in the plug 23 secured centrally in the lower wall of said.

the chamber formed between the lower portion of the plug 23 and the upper portion24 of the drip cylinder 27 is a leather disk 26 and a screen 25 thereunder-which cover the channel of the drip cylinder. The upper end of the valve stein 20 is provided with a knob for turning the same. The upper portion of the dome is provided with an opening surrounded by a projecting wall 31 which supports the threaded cap 82, having through a hollow stem centrally extendin said cap. The lower end of said cap 32 supports a cylindrical screen 33. The upper end of said tank is provided with ears projecting therefrom and cent-rally supporting screws 17 penetrating ears projecting from the lower portion of said dome, the

upper ends of said screws being provided with wing nuts l8 whereby said dome is secured to said tank. The washer or gasket 15 tests in seats in the ears of said. dome as shown. The lower end of said tank is provided with an opening and coupling 8 in which is secured the worm 9, the upper end of which penetrates and is supported in an opening in the chamber 10 containing cotton 11. The upper end of said bell is penetrated by and supports screw-cap 13 having tubes 12 penetrating said cap and secured therein.

To operate the apparatus water is poured D rod 28 is made of such diameter as shown to allow sufficient space for the water todescend with equal pressure and to give theproper supply for the best result. Water contacting with the carbid the evolution of the gas commences and escapes through apertures 14 in the inner wall of the tank to the chamber between the interior and exterior walls of said tank and then into the coupling 8, rising'in the worm 9 wherein the gas is cooled, and then purified in its passage through the cotton in the chamber 10 of larger diameter than the cylinder 27 per- -mits organic matter or .impurities in the descending water to remain therein, the pure water discharging through aperture 30.

. In the action of the generator the dust or residue of carbid drops from the basket to the bottom of the tank, and should the pressure of gas in the tank increase-to an undue extent the increasing pressure of the same against the disk 26 which is flexible and preferably of leather will close the apesture in the bottom ,of the valve preventing the downward passage of water and consequently decreasing the evolution of gas. In the operation of said generator stability of light may be obtained, olfensive odor is prevented by permitting escape of gas at the bottom only, danger of explosion is rcmoved and economy in the consumption of gas is attained. Although. for filtering,l' prefer to use cotton in bell 10, other suitable filtering material may be used therein. The shaking of said generator, such as may occur in the movement of a vehicle in which.

the generator may be used, will cause the movement of the rod 28 in cylinder 27, thereby freeing the cylinder from foreign matter which may be sticking therein; also said rod will cause the escape of water from the cylinder drop by drop as desired for the proper evolution of the gas for by the omission of said rod the water would run from said cylinder in a steady stream. The cap 29 is removably secured to the lower end of cylinder 27 as shown so that any sediment collecting therein may be removed without disconnecting said cylinder.

I claim:

1. In an acetylene gas generator in combination with a tank and a water dome having a bottom aperture extending therethrough mounted on said tank; a plug having a narrow central opening secured in said aperture and a wall projecting clownwardly in said tank; a drip cylinder having a closed lower end and an upwardly projecting wall secured in said downwardly projecting wall and forming a chamber be tween said plug and cylinder, and said cylinder having a side opening above its base; a rod resting loosely insaid cylinder; a screen resting loosely in said chamber and a disk resting on said screen.

2. In an acetylene gas generator in combination with a tank and a water dome having a bottom aperture extending theredisk resting on said screen.

3. In an acetylene gas generator in combination with a tank and a wate! dome having a bottom aperture extending therethrough mounted on said tank; a plug having a narrow central opening secured in said aperture, and having a wall projecting upwardly in said chamber containing avalve seat, and a wall projecting downwardly in said tank, a valve stem turnably mounted in the roof ofsaid dome and engageable with said valve seat, a drip cylinder having an open lower end and an upwardly projecting wall secured in said downwardly projecting wall and forming a chamber between said plug and cylinder, a cap secured removably onthe lower end of said cylinder and having a side opening above the base thereof; a rod resting loosely in said cylinder, a screen resting loosely in said chamber and a disk resting on said screen.

In testimony whereof I afiix my signature, in presence of two witnesses.

JOSEPH CORROYER.
