Serial No. 386,517'.

To all whom t may concern:

Be it known that I, SAMUEL T. RUSSELL, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification, reference being had therein to the accompanying drawings.

The present invent-ion relates to acetylene gas generators, and more particularly to that type of generators known as the water feed generator, in which a fixed quantity of carbid is placed and the water fed to the carbid in a sul'licient quantity to produce the desired quantity of g'as. rIhe object of the invention is to provide a generator of this character which will be or' simple and inexpensive construction, easy and sate to operate, and which will have a high per cent. oit etliciency.

To this end it a further object of my invention to provide an improved carbid receptacle in which the water is admitted to a. portion only oi the carbid at one time: and to provide an improved means -for feeding the water to the carbid receptacle, which means is regulated in accordance with the amount of gas contained in the gas holder.

`With these objects in view my invention consists in certain novel features of construetion and in certain parts and combinations hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view of a complete generator embodying my invention; Fig. 2 is a sectional view, taken vertically through the carbid receptacle` showing the gas holder and water receptacle in elevation; Fig. 3 is a front View of the device showing the several parts in elevation; Fig. 4: is a sectional detail view of the carbid receptacle; Fig. is a perspective View et cnewo'f the carbid pans; l*l ig. 6 is a sectional detail view of the .lilterg Fig. '7 is a sectional detail view ot the double stop and drain cock; and l? S is a sectional detail vView of the adjustable nozzle for the discharge spout of the water receptacle.

In these drawings, I have shown a generator embodying my invention in its preferred form, but obviously, the detail construction and arrangement of the several parts could be altered without departing from the principle of my invention. ln

the 'lorm ot generator here shown l employ a carbid receptacle l, which preferably consists ot an outer casing 2 which may be ot any suitable shape and size and is provided at a point some distance above the lower edge thereof with a bottom 23. A\rranged within the outer casing 2 and above the bottom 3 is an inner casing fl forming within the same and above the bottom 3 a generating chamber adapted to contain the carbid vessels and forming between the inner casing -land the outer casing 2 a water chamber lilounted within the generating chamber formed by the inner casing` Llare a plurality ot' carbid pans 6 which may be oft' any suitable construction and which may be arranged in any desired manner, but, in the torni here shown, have provided a generating chamber which is substantially rectangular in shape, and have provided the carbid receptacles or pans of rectangular shape in order that they may lit snugly within the generating chamber, and have provided each pan with suitable flanges 7 adapted to extend between the pans and between the pans and the side wall, thus providing at all times a sullicient space about. the sides ol the pans for the circulation of water. Each pan is provided with one or more suitable apertures 8, termed in the side wall. thereof. These apertures are 'termed at a dillcrent level in each of the pans contained within the generating chamber so that the water, as it rises within the generating chamber, will reach the apertures of each pan successively, and, through these apertures, will reach the interior ot the pans and the carbid contained therein. i prelcr to employ two apertures S in order to lessen the liability oit the same becoming stopped or partially cloggedand thus interlferring with the [low of the water.

,is here shown, the carbid pans are supported upon legs 9 which are shown as extensions ofthe pan and serve to support the pan above the bottom oitthe generating chamber. This is desirable in that it provides :tor a free circulation of water about the pans which serves to reduce the heat produced by the generation oit the gas. But this construction is not necessary as the pans may be supported in any desirable manner. A suitable closure is provided for closing the upper end of the generating chamber against the escape of gas therefrom, and this Iso closure prefeiably consists of a hood 10 having a downwardly extending iange 11 adapted to enter the. water chamber 5 surrounding the generating chamber and thus form a liquid seal. This flange may be made of a length sufficient to provide a water seal. The central portion of the hood 10 is depressed in the form of a basin, as shown at 12, the depth of the depression being such as to bring the bottom of the basin 12 into contact with the upper ends of the carbid pans when the hood 10 is at rest upon the upper edge of the outer casing 2. This basin serves two purposes, first, it retains the carbid receptacles or pans in their proper positions in the generating chamber and prevents their floating as the chamber lls with water; and second, by filling the basin 12 with water the heat produced by the generation of the gas is materially reduced. A water supply pipe 13 extends through the bottom 3 and upward into the generating chamber with its upper end slightly beneath the level of the lowest inlet aperture 8 in any of the pans. This pipe exten ds outwardly through the side walls of the casing 2 where it is provided with a downwardly extending bend 141 to form a water trap and thence extends upwardly and is provided with a suitable funnel 15 adapted to receive water from any suitable source. A suitable outlet pipe 16 extends through the bottom 3 of the generating chamber upward to a point near the top of the generating chamber, and preferably extends through an aperture in the hood into a dome or cap 17, which is secured to the bottom of the basin 12, and surrounds the aperture through which the pipe 16 extends. This cap or dome enables the pipe to be so placed as to draw off the gas without the water from the generating chamber being able to enter the same. This pipe also extends outwardly through the side wall of the casing 2 and thence into the gas holder, as hereinafter described.

The pipes 13 and 16 are preferably provided with suitable stop and drain cocks which are adapted to be actuated by a single operating mechanism. As here shown, a single valve casing 18 is employed for both the stop and drain cocks and is provided with two three-way valve openings, as shown, two of the openings of each series being adapted to receive the ends of the pipes 16 and 13 respectively, while the third opening of each series, as shown at 19, serves as a drain for said generating chamber. A single valve plug 2O is provided with two series of openings for controlling both the pipes 13 and 16, these openings being so arranged that, when the valve plug` is in its open position, the opening through the pipes 16 and 13 will be continuous, but when in its closed position, the inner ends of these pipes, that is the ends connected with the generating chamber, will be connected with the atmospherethroughthe drain openings 19. The valve plug 2O is preferably Yprovided with a suitable Valve stein 21 having its upper portion 2.v turned at right angles thereto and so positioned relatively to the plug 20 that, when the plug is turned to its open position, to provide a continuous passage through the pipes 16 and 13, the horizontal portion 22 of the rod 21 will lie above the hood 10 of the carbid receptacle 1, which is preferably pro-` vided with suitable ears or clips 23 on the opposite sides thereof, beneath which the horizontal portion 22 of the rod extends and which serves to prevent the displacement thereof. A suitable bracket 2l is preferably mounted on the adjacent wall of the water receptacle and engages the rod 21 and serves to support the same in a vertical position. Thus, it will be seen that so long as the pipes 13 and 1G are in open communication with the water supply and gas holder, respectively, that the closure for the carbid receptacle and generating chamber will be locked in position and that the Vsaine cannot be removed until the valve controlling the pipes 13 and 16 has been operated to cut off the generating chamber from the water supply and gas holder and connect the same with the drain cock, whereby any surplus gas or water remaining in the generator is wit-hdrawn.

By providing the inlet pipe 13 with a drain cock, l am enabled to utilize that pipe as a combined inlet and outlet pipe, and, inasmuch as the upper end of this pipe lies in a lower level than any of the inlet apertures in the carbid pans, it will be apparent that the water in the generating chamber can be drawn off to a point below these inlet apertures without completely emptying the chamber. Thus, when the refilled carbid pans have been replaced in the generating chamber, the water therein will rise to a point just below the inlet apertures and the amount of water which it will be necessary to feed into the chamber before it reaches the carbid and the device becomes operative will be materially reduced.

The pipe 16 leads from the generating chamber to a suitable expansible gas holder, which is here shown as consisting of an outer casing 25, which is preferably cylindrical in shape, and forms a water chamber within which is mounted an inverted gas bell 27 adapted to rise and fall within said water chamber. The outer receptacle 25 is provided with suitable guide rods 71 extending above the same and adapted to engage guide lugs or apertured brackets 7 2 carried by the gas bell near the upper end thereof. These brackets may be of any suit-able construction, and, as here shown, one of the same is provided with an outwardly extending portion, forming a bracket 62, and is adapted to re- Cao ceive the rod 61. The rods 71 form a guide for supporting' the gas bell iu its proper position when the same has been moved upwardly by the gas. These rods may be supported from the outer receptacle Q5 in any suitable manner, but 1 prefer to secure each rod in an apertured bracket 7 3 which is secured to the side of the receptacle Q5 in any suitable manner and is provided with a set screw 74; extending into the aperture and adapted to engage the rod 71 to hold the same in its adjusted position. By the use of the apertured bracket and set screw the guide rods 71 can be moved downwardly until their upper ends are approximately even with the upper end of the receptacle 25, thus greatly facilitating the removal of the gas bell 9,7 from the water receptacle 25. The water receptacle Q5 is preferably provided near its upper end with an inlet apeim ture 75 surrounded by a filling lip 7G, thus providng means for renewing the supply of water within said receptacle.

The outlet pipe 33 extends from a point within the gas holder and is connected by a joint 34 with the service pipe 35 which extends through a suitable filter 3G and thence to the burners or other source of consumption. This filter may be of any suitable construct-ion, but preferably consists of a sheet metal receptacle adapted to be filled with raw cotton or similar filtering' material for removing impurities from the gas and is provided with a suitable bracket 37 for securing the same to the side wall of the casing or other suitable supporting' surface. 1t is also provided with a suitable hand-hole in the upper end thereof which is provided with a suitable closure 3S. The pipe 35 is provided with a suitable cut-off valve 39 which is preferably located in the horizontal portion thereof and is provided with an upwardly extending valve stem 40, which preferably extends to a point near the upper end of the filter 36, where it is provided with a horizontal handle portion al1 which is so posi tioned relatively to the valve that, when the valve is open, the horizontal portion ell will extend above the closure 3S of the hand-hole and prevent the removal of the same until the valve has been operated to cut ofi'l the supply of gas from the service pipe.

The water is fed to the funnel 15 of the water supply pipe in any suitable manner, but I prefer to employ the means herein shown which consists of a suitable receptacleI 53, pivotally mounted near the carbid receptacle, and preferably consists of a cylindrical tank having at its opposite ends suitable trunnions 511 adapted to engage bearings which are supported in any suitable manner adjacent to the carbid receptacle, and are here shown as formed in the upper end of a suitable supporting frame 5G. This tank has a suitable inlet which is provided with a closure 5i' and has on one side thereof a discharge spout 53 extending from the lower portion of the cylindrical tank and adapted to discharge into the funnel 15 of the supply pipe. The receptacle 53 is provided on the side opposite that in which the discharge pipe 5S is mounted with a suitable weight 5f) which may be of any suitable character and which serves to so ncrease the weight on that side of the cylinder as to cause the receptacle to rotate about its pivotal support until a suitable stop G0, mounted on the end of the receptacle, comes into engagement with the supporting` frame 56, and, with the stop G0 in engagement with the frame, the discharge spout 5S has been elevated to such a position that the water cannot flow therefrom. Suitable means are provided for turning' the water receptacle about its pivotal center against the action of the weight 59 and thus permitting the water to flow to the carbid. rlhis means is preferably actuated by the expansible gas holder, and, in the form here shown, consists of a rod (31 secured at its upper end to a bracket G2 which carried by the gas bell 2T. This rod extends downwardly and through an apertured lug G3 carried by that side of the receptacle to which the discharge spout is connected and is provided with a stop (Sel adapted to engage the lug ($3 and rotate the receptacle as the rod moves downward with the gas bell 27. Thus, it will be seen that as the gas bell rises, the weight 59 will rotate the receptacle and move the discharge spout into inoperative position, and that as the gas is consumed and the bell 27 drops, the stop G-l on the rod G1 will engage the lug G3 and rotate the receptacle in the opposite direction, thus, moving the discharge spout into operative position and permitting the. water to feed to the carbid. I preferably provide the discharge spout 5S with an adjustable nozzle G5, by means of which the amount of water discharged therefrom may be regulated. As herein shown, the nozzle (l5 is provided with a valve seat (E6 and a valve (37 which is provided with a screw-tln'eaded shank (3S mounted in the end of the nozzle G5 and provided with a milled head (39 for operating the same, thus, enabling the size of the discharge opening to he varied. I also prefer to provide the receptacle with a suitable overliow aperture which is preferably located in one end of the cylindrical tank, as shown at TO, and is so located that. when the discharge spout is in its inoperative position. the water will escape through the aperture .70 before it will rise high enough to pass out of the discharge spout.

The operation of my improved generator will be readily apparent from the foregoing descriptions of the several parts thereof. 1n brief, it is as follows ln preparing the machine for use, each of the carbid pans 6 are iilled with calcium carbid and are then placed in position within the generating chamber and water is introduced into the same until it reaches a point just beneath the level of the lowermost inlet aperture in any of the pans. The. pivotal water tank 53 is filled with water, and, assuming that the gas holder is practically empty and the bell 2T near its low rinost position, the stop 6e on the rod 61 will tilt this tank forward into a position which will permit of the water nowing through the discharge spout 5S into the funnel 15 of the water supply pipe 13. As the water enters the generating chamber through this pipe it gradually rises within the chamber until it enters the lowermost apertures of the carbid pans, thus generating gas which escapes from the carbid pans into the generating chamber, thence through the outlet pipe 16 to the gas holder where it is forced to pass through the water in the water receptacle of said gas holder and thus washed and cleansed from impurities. The gas accumulating in the gas bell above the water in the holder causes the gas bell 27 to move upwardy, and, as the gas bell moves upwardly, it carries with it the rod 61 and stop 64e, thus releasing the pivoted tank 53 and permitting the weight 59 to rotate the same about its pivotal center and move the discharge spout 58 into its inoperative position, thus stopping the flow of water to the generating chainber and likewise interrupting the generation of gas. The gas which has entered the gas holder passes out through the outlet pipe 33 to the service pipe and through the filter 3G to the burners. As the gas within the gas holder is consumed, the gas bell Q7 moves downwardly and again brings the stop 6d, on the rod 61, into engagement with the lug 63 of the water tank and again moves the discharge spout 58 into operative position and starts the generation of gas. All moisture and products of condensation accumulating within the inlet and outlet pipes within the gas holder drain downward through the extensions from the lower ends of those pipes into the water receptacle, the water in said receptacle forming a seal and preventing the escape of gas from said pipes. Thus, it will be apparent that 1 have provided an acetylene gas generator of the character described which is simple in construction and easy of operation and which will have a very high per cent of eiiiciency. 1t will be further apparent that this result is accomplished by providing the several parts of such a construction and arrangement that they will cooperate one with the other to provide an automatic feed of the water to the carbid, which feed is under perfect control and is regulated to feed the water to the carbid only in such quantities as is necessary to generate the required amount of gas, thus insuring the' complete consumption of the carbid.

1 wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for olovious modiiications will occur to a person skilled in the art.
