HENRY BRYANT, OF ARANSAS PASS, TEXAS.

ACETYLEN E-GAS G ENERATOR.

SPECIFICATION forming part of Letters Patent No. 633,545, dated September 19, 1899.

Application iiledSeptember 10, 1898. Serial No.690,693. (No modelJ T0 all whom it may concern.-

Be it known that I, HENRY BRYANT, a citizen of the United States, residing at Aransas Pass, in the county of San Patricio and State of Tenas, have invented a new and useful Improvement in Acetylene- Gas Generating Apparatus, which is made and used substantially as hereinafter set forth and as shown in the accompanying drawings.

This invention relates to acetylene-gas generating and storing apparatus; and its object is to provide a simple, compact, and economical means for automatically generating said gas.

The invention consists in the combination of a generator of approved construction, a water-supply tank, means connecting said tank and generator, a gas-holder, an independent gas-reservoir, and means for automatically controlling the generation of Vthe gas by the action of the holder, all as hereinafter fully described, and illustrated in the accompanying drawings, in which- Figure l is an elevation, partly in section, showing my generating apparatus in its almost normal position. Fig. 2 isa sectional elevation when the gas-holder is'filled with gas. Fig. 3 is a vertical section of the generator. Fig. 4 is a detail showing arrangement of spring-lingers for lifting, and Fig. 5 shows a modification of the generator.

Referring to the accompanying drawings, A designates the generator, which may be square or of any other shape, constructed of metal or any other suitable material and resting upon legs. The generator at its top is provided with a central opening havinga suitable closure A', and ator near the bottom and to one side :is also a suitable opening and a door A2 for closing the same, said door being securely hinged to the casing, a cotterbar and screw A3, together with a suitable catch and packing means, being employed for fastening the door in position and effecting a gas-tight joint.

Midway the generator and supported u-pon ledges secured to the walls of the generator is located an open carbid-basket B, formed Aof some reticulated material 'having a mesh sufficient to allow the passage of the hydrate of lime and of a size to hold a suitable charge of carbid. Above this basket, beneath the central opening and within the generator, is located a spray-pipe B2, provided with openings for directing a spray of water upon the carbid contained within the basket. Ben eath the basket and resting upon the bottom of thegenerator is located an ash-pan B for the reception of the hydrate of lime resulting from the decomposition of the carbid and water.

The basket B at its ends is provided with hook-ears m for lifting it. M represents a a rock-shaft located within the generator, to

one side thereof, and journaled with packing in the walls of the same, one end of said shaft extending entirely through said generatorcasing to the outside. To each end of said rock-shaft and within the generator are secured spring-arms M, arranged so as to engage with the hook-ears nt. To the outer end of the shaft, which extends entirely through the casing, is secured a long lever M2, the object of which, together' with the rock-shaft and spring-arms, is to agitate the carbid-basket either by hand or automatically by means hereinafter described.

The letter H designates a gas-holder consisting of au open-topped tank having located centrally thereina closed high-pressure gas-reservoir K,which,together with the tank, forms an annular chamber or seal for the bell H". As shown, the outer wall of the tank eX- tends to some distance above the top of the gas-reservoir, whereby said reservoir may be practically surrounded by water and protected thereby, at the same time acting as a wind-break lor the rising-and-falling bell. Said bell may be constructed to receive suitable wei-ghts, as shown.

D designates a water-tank which is divided into two compartments D D2 by means of a suitable transverse partition somewhat lower than the walls of the tank. To the said transverse partition and Within the compartment D2 is secured a trip d. Secured to the tank D by any suitable means is a water-supply pipe C, leading downwardly an d connected to the spray-pipe B2. Said pipe C is provided with a check-valve C2, constructed in a wellknown manner, so as to allow the water from the tank D' to pass to the generator and pevent the passage of gas in case the pressure of the gas in the generator exceeds the hydrostatic pressure of the water in the pipe C.

ICO

l3 designates a valve located in the pipe C and is shown closed, whereby the water in the tank D' is prevented from flooding the generator when the carbid has become exhausted and the bell H passed below the normal line.

G' designates the gas-outlet pipe leading from the generator to the pipe G and the burner E. The pipe Gl connects the generator at a'point midway or below the carbidbasket, whereby the gas in passing from the generator is caused to pass downwardly through the carbid, and thereby be more or less dehydrated. The pipe G is provided with the usual check-valve g, which allows the gas to pass from the generator to the pipe G', but prevents the return of the gas when the generator is opened for recharging or cleaning.

G4 represents a purifyingchamber located within the pipe G and filled with cotton, cloth, sand, or similar material dampened with some non-volatile hydrocarbon, so as to catch and retain atoms of heavy hydrocarbon in the fresh gas, to which are attributed the tendency to form specks ot' soot in burning and clog up the burner-tip in use.

G2 designates a pipe connecting the pipe G and leading to the interior of the gas-holder or bell, and it also acts as a tie-rod for securing the heads of the tank K against internal pressure within the outer tank of the gasholder, as clearly shown. G3 designates-a pipe connecting' the pipe C with the interior of the gas-reservoir K for conducting the highpressure gas to the said reservoir hereinafter described.

F2 designates an escape-pipe which leads to the external air, a chimney, or other place of safety and is connected to the pipe G3 and provided with a weighted safety-valve F'.

F designates an internally-weighted valve and is located in a branch pipe connecting the pipes F2 and G2. The object of the safetyvalves F F is, the first, to relieve excessl ot' pressure in the holder H, and, the second, to relieve excess of pressure in the reservoir K.

I designates a turning plug located in the water-supply pipe C and gas-supply pipe G and is used for regulating the supply of water from the tank D to the generator andfor regulating the passage of gas from the generator to the burner and gas-holder. The valve I is provided with lever-arms I I2, to one end of which the chain t' is attached, the opposite end being weighted by any suitable means in a well-known way, whereby the valve is normally held open.

L designates an upright postwhich may or not be secured to the gas-holder tank. To the upper end of this upright is hinged a lever-arm L, carryingintermediate its ends idle-wheels l Z2, over which passes a chain t', which is secured at one end to the bell II and at its opposite end to one end of the lever-arm of the valve I, whereby the rise and fall of the bell automatically controls the valve I and correspondingly regulates the supply of water to the generator and the passage of the gas therefrom to the burner.

At or near the end of the leverLis secured a chain z2, passing down and connected to the lever M2. c, is also connected to the lever L and dips into the tank D2. A chain i' also connects the lever L and arm I4 of the valve I3 to limit the downward movement of said arm and at the same time assure the closure of the valve I3. I p

Operation: In the operation of my apparatus as above described the generator having been charged with carbid and the tank D with water, the bell H being in its lowermost position and the valve I turned to open both pipes C and G, the valve I3 is manually op` erated by the lever It1 to permit water to pass to the generator through the valv'e I and spray-pipe B2, whereupon acetylene gas is instantly generated and conducted to the burner E and burned, the excess gas passing to the gas-holder I-I through the pipe G2 and stored therein until said holder is raised sufficiently high to close the valve I, when the supply 'ot water to the generator and the passage of the gas from the generator direct to the burner through pipe G will be cut oi. The gas for the burner or burners, more or less, as found wanting, will then be taken from the holder until said holder descends sutliciently to again open said valve I to supply more water to the generating-chamber. Thus it will be seen that the generation of gas is continuous and automatically regulated. The valve I3 is maintained in an open position by the bell and only closed when the bell passes to its lowest position, thus preventing the Iiooding of the generator.

It is a Well-known fact that in this class of gas-generators gas will continue to be generated for some time after the water-supply to the generator has been cut ott. This is due largely to the hygroscopic character of the carbid and the excess of water admitted to the generator in the first instance and retained by the hydrate in contact with the carbid. In order to make provision for the storage of gas so generated, a reservoir K has been provided, to which such gas is conducted through the pipe G2, which gas upon the opening of the valve I passes to the burners and holder II.

As shown in the drawings, Fig. 1, the bucket O is in its lowermost position in the watertank D. Upon the rise of the bell the dome thereof coming in contact with the lever L raises said lever and with it the bucket C',

-Which latter in rising is caught by the trip d and bail c and emptied in chamber D', thus supplying said chamber with the necessary water for the generation of gas. At the same time and through the chain z2 the lever M2 is raised and by it a rocking motion imparted to the rock-shaft M, and the basket containing the carbid is agitated to free the carbid A bucket C', provided with a bail IOS IIO

of any adhering ash, which is precipitated and collected in the pan B', to be removed upon recharging the generating-chamber.

In the modification shown in Fig. 4, B'l represents a screen, and M4 an eccentric or cam for agitating the screen by means of suitable connections with the lever L. derstood that this form of device can be readily substituted for the basket shown in Fig. l without departing from the spirit of my invention.
