- the generator may7- be termed a high pressure generator as distinguished from the ordinary generators of this type which are generally so designed as to prevent the accumulation of any high pressure.
- the gas in the generator can be brought to any desired degree of pressure and that degree maintained at all times.

Specification of Letters Patent.
Application tiled February 20, 1912, Serial No. 678,5329. Renewed April 5, 1913. Serial No. '759,198'.
To all whom t may concern:
Be it known that I, GEORGE H. DAvis, citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Acetylene-Gras Grenerators, of which the following is a specication, reference being had therein tothe accompanying drawing.
This invention relates to an improvement in acetylene gas generators and more particularly to a portable generator of this character which is particularly adapted for use on automobiles, launches and the like.
One of the objects of the present invention is the provision of a generator of this character which will furnish the burners with gas at a uniform predetermined pres sure.
A further object of the invention is the provision of a device of this character which is provided with means for starting the generation of the gas and which is of such a construction that it will, when once started automatically, generate gas proportionately to its consumption at the burners.
A further object of the invention is the provision of a device of this character which is compact, and which is of such a form that it may be readily secured to the running board of a vehicle in the manner ordinarily adopted for presto-light or other gas storage tanks. y Other objects of the invention will be apparent from the detailed description hereinafter when r-ead in connection with the accompanying drawings forming a part hereof, wherein a convenient embodiment of the invention is illustrated, and wherein like characters of reference refer to similar parts in the several views.
In the drawingsrFigure l is a longitudinal section of the improved generator; Fig. 2 is a front elevation thereof; Fig. 3 is a sectional view on line 3 3 of Fig. l; Fig. 4 is a sectional view on line P-4 of Fig. 2; Fig. 5 is a sectional view on line 5-5 of Fig. 1 and Fig. 6 is a sectional view showing a modified form of valve whi'ch may be used.
Referring now more particularly to the drawings, A designates the casing of the generator, which in the form of the invention illustrated is in the form of an elongated metal cylinder, the forward end of which is closed by a head A and the rear end of which is open. Positioned within the casing A intermediate the ends thereof is a partition A2 which serves to divide the casing into a water chamber A3 at the front end thereof and a carbid chamber A1 at the rear end thereof. The open end of the casing A is normally closed by a cap B which may be removed when it is desired to charge the carbid chamber A4. Any suitable form of closure may be used for this purpose, but I have found that the particular form shown in the drawings is very efficient for this purpose and forms an absolutely gas tight 'joint between the cap and the casing.l In the form of' the invention illustrated in the drawings, the casing is provided with a threaded portion onto which is screwed the cap B, which cap is provided with a portion b which is adapted to directly overlie the rear edge of the wall of the casing A.
Interposcd between the rear edge of the wall of the casing A and the portion b of the cap B, is a gasket B of rubber or any suitable flexible material and a disk B2 of metal which has a smooth surface. Interposed between the surface of the metal disk B2 and the portion Z) of the cap B is a lubricant of any suitable character. With this construction, when the cap B is threaded onto the casing A, the gasket B will, as soon as it contacts with the edge of the rear end of the wall of the casing A, be held against further rotation, and the metal disk B2 will also be held against further rotation by reason of the frictional engagement between the same and the flexible gasket B. As the cap B is further screwed to position, it will readily rotate over the surface of the metal disk B2 owing to the lubricant which is interposed therebetween. As the flexible gasket B is held from rotation instantly it contacts with the rear edge of the wall of the casing, it will be seen that it will not become torn or distorted and that a perfect gas tight joint will be formed between the cap B and the interior of the carbid chamber.
Positioned within the carbid chamber Ai is a carbid receptacle C which is so supported that it may shift axially relative to the casing A -so that regardless of the position in which said casing is placed, the carbid receptacle will occupy such a position as will cause the proper retention of the carbid therein. The carbid receptacle may be supported in any convenient manner for obtaining this result. In the embodiment of the invention illustrated, I have shown the carbid receptacle in the form of an open topped boX or basket having a removable screen therein for the support of the carbid and the end walls of which are j provided with trunnions c which loosely engage sockets c formed respectively in the partition A2 in the case A and in the metal disk B2. From 4this construction it will be seen that the carbid receptacle C is held in its suspended position by means of the closure B and that when the closure B is removed, said receptacle may be readily withdrawn from the casing A.
Secured within the lower portions of the front wall A of the casing A, and projecting within the water chamber' A3, is a pump barrel, D, the front end of which projects outwardly beyond the front bwall A of the casing and has connected thereto in any suitable manner, a cap D. Threaded on the cap D is a stutling box D2 and working within the stuffing box D2 and the cap D is a plunger rod D3, the inner end of which carries ay piston D4 which is adapted to slide within the pump cylinder D. Secured to the outer end of the piston rod D3 is a suitable operating handle D5 by means of which the piston rod may be reciprocated. rlhe operating handle D5 is provided with an interior-ly threaded collar D*i which may, when desired, be caused to engage a thread formed on the outer surface of the stulling box D2, so that the piston rod D3 will be held against movement. The pump cylinder or barrel D is provided with a plurality of openings Z therein which are positioned in advance of the piston D1 when the same is locked against movement, and which serves to establish a communication between the water chainber'A3 and the interior of the pump barrel or cylinder. Communicating with the front portion of the pump barrel D which projects beyond the front wall A of the casing is one end of a pipe or tube E, which pipe extends upwardly from its connection with the pump barrel through the front wall of the casing, the partition A2 in the casing, and to the upper portion of the carbid chamber A4. rl`he portion of the pipe E extending within the carbid chamber A4 is provided with a downwardly turned end e and positioned directly below said downwardly turned end portion is a trough e which is provided with downwardly inclined end portions and is adapted to receive water from the downwardly turned end portion of the pipe E and direct the same into the carbid chamber in a manner to be hereinafter more particularly set forth. The trough e may be supported in the carbid chamber A4 in any suitable manner. The end of the pipe E which is connected to the pump barrel or casing D is extended forward for a slight distance before the pipe is extended through the front wall A of the casing, thus forming a loop or yoke e2 in the pipe l1 which pro jects forwardly from the connection of said pipe with the pump barrel. If desired, the yoke or loop portion of the pipe E may be provided with' a suitable removable cap e3 so as to permit access to be had to the portions of the pipe E located in the water and carbid chambers, thus enabling these por` the interior of said tube is not in communi` cation with the water chamber. The portion of the tube F which projects into the carbid chamber A4 is, however, perforated so that gas generated in the carbid cham* ber may pass freely into the tube. The tube F is provided adjacent the front end thereof with a plurality of disks f of chamois or other water resisting material which serves to dry the gas as it passes therethrough.
Any suitable filtering material f is positioned within the tube F in rear of the chamois disks Threaded into or otherwise connected to the front end of the tube F is a valve casing Gr the interior of which communicates through the port g with the interior of the tube F, the passage of gas through the port G being controlled by a needle valve g which is threaded in the valve casing G and is adapted to coperate with a seat formed adjacent the front end of said port.
Secured in the front wall A of the casing A is a safety valve chamber H, the inner end of which is provided with a port it which establishes communication between the interior of the safety valve chamber H and the water chamber A3 of the generator. The safety valve chamber H is provided adjacent the fro-nt end of the port L therefor with a valve seat L against which the valve 7a2 is normally held seated by a spring h3, thus closing the communication between the safety valve chamber and the water chamber. One end of the spring h2 is preferably seated against the cap 7L* which is adjustably mounted in the valve chamber H so that by adjusting said cap the tension of the spring can be varied to cause the valve h2 to open when any desired pressure is reached in the water chamber. Connecting the needle valve chamber Gr and the safety valve chamber H is a pipe i and communicating with said pipe intermediate the needle and safety valve chamber is a gas feed pipe l which leads to the burners and in which is interposed a suitable valve i for controlling the flow of gas to the burners.
K designates a gas storage tank which is connected to the pipe I between the valve z" and the pipe z' by a pipe in which is interpo-sed a valve 7a of any suitable construcstruction. A suitable outlet pipe k2 extends from the tank K and there is interposed in such outlet pipe, a valve .7:13 of any suitable construction for controlling the flow of gas therethrough. Secured in the central portion of the front wall A of the casing A is a filling tube L, the outer end of which is normally closed by a suitable cap L of any desired construct-ion.
Having described the construction of the improved generator, I will now set forth the manner of using the same and the operation thereof. The desired amount of carbid is first placed in the carbid receptacle C and the same is secured in the carbid chamber A4 of the casing by means of the cap B in the manner heretofore described. The generator is now placed end to end with the water chamber uppermost and the water chamber is filled with water through the filling tube L. During this operation, it will be impossible for any of the water in the water chamber to pass through the tube E into the 'carbid chamber because of the yoke or bend. e2 in the tube which is positioned above the water level. The generator is then secured in a horizontal position to the running board or other part of the vehicle. l/Vith the generator in this posi` "tion, to start the same the handle D5 of the pump is rotated a sufficient amount to disengage the threaded collar D6 thereof from the stuffing box D2. rl`he handle may then be manipulated to reciprocate the piston D4 in the pump cylinder D which serves to force a portion of the water from the water chamber A3 through the pipe E and into the trough e from whence it drips onto the car- `4.5 bid in the carbid receptacle C. During this operation, the needle valve g is kept closed so that as soon as the gas is generated in the carbid chamber A4 some of the gas will pass into the downwardly extending portion e of the pipe E, through said pipe into the 5 in the water and carbid chambers.
tion being secured in the front wall pump barrel or cylinder D, out through the openings cl in said pump barrel or cylinder, and into the upper portion of the water chamber A3, thus equalizing the pressure One or two reciprocations of the pump will suffice to generate eno-ugli gas to obtain the desired pressure in the water and carbid chambers, a pressure gage M of any suitable construc- A of the casing A to indicate when the desired degree of pressure has been reached. As soon as the desired pressure is obtained in the water and carbid chambers, the piston is locked to hold the same against any accidental movement by engaging the threaded collar D6 of the handle D5 with the stuffing box D2. As the pressure in the water and carbid chambers is equalized, any desired degree of pressure may be utilized, so that if the generator is used on cars employing acetylene under pressure as a starting agent, the operator can, by means of the pump, bring the pressure in the generator up to the desired amount, which pressure will be automatically maintained during the subsequent operations of the generator. The generator is now ready for use and by opening the needle valve g and the valve i in the gas supply pipe I, gas will pass lfrom the carbid chamber to the burners. rIhe generator will now act automatically to supply gas to the burners at substantially a constant pressure regardless of the fact whether the burners are adjusted to burn with a high or low flame. This result is obtained by reason of the fact that as soon as the pressure in the carbid chamber is diminished by the passage of some of the gas therein to the burners, the pressure o-f the gas in the water chamber will serve to force some of the water from the water chamber through the pipe E into the carbid chamber, thus generating a fresh supply of gas and immediately equalizing the pressure in the chambers. Dur` ing this action, there is temporarily created in -the generating chamber, a pressure slightly in excess of that in the water chamber which causes a slight amount of gas to pass from the generating chamber through the pipe E and into the water chamber, thus increasing the pressure therein to a slight extent. Immediately this occurs, however, the safety valve h2 is opened, and gas is allowed to escape from the water chamber into the gas supply pipe I until the pressure again reaches normal.
Then the burners are not being used, the valve z" in the pipe I is closed and the valve 7c in the pipe K leading to the storage chamber is open. By this construction it will be seen that any gas due to after-generation or due to any excessive pressure which might be developed in the generator from any source whatever, would pass to the storage chamber. rlhe gas in this chamber can be utilized for any desired purpose, such as starting the engine o-f an automobile or the like or it may, if desired, be used in an emergency at the burners. Vhen it is desired to again connectthe generator to the burners, the valve c" in the gas supply pipe is opened and the valve 7c controlling the iiow of gas to the storage chamber K is closed.
In Fig. 6 of the drawings, I have illustrated a slightly modified form of valve casing which is coupled to the outlet end of the tube F, this form being particularly useful where the generator is adapted to be used not only for supplying gas for the lamps but also for supplying gas under pressure to an acetylene starting device. In the form of the invention the valve casing which communicates with the pipe F is provided with two branches G4 and G5, one of which is adapted for connection to the burners and the other of which is adapted for connection to the gas supply pipe of a suitable acetylene starter, the passage of gas through said passages beingl controlled by suitable needle or other valves. In this form of the invention, one of said valves is conveniently set to cause the reduction of the gas which passes through the branch controlled thereby to the desired degree of pressure for use at the burners, while the other valve is of such a construction that by proper adjustment thereof the gas which passes through the branch controlled thereby can be caused to pass therethrough either at the pressure maintained in the generator or at a lesser pressure.
From the construction above described it will be noted that the generator may7- be termed a high pressure generator as distinguished from the ordinary generators of this type which are generally so designed as to prevent the accumulation of any high pressure. IVith the present device, by means of the pump which is used to prime the generator and of the safety valve, the gas in the generator can be brought to any desired degree of pressure and that degree maintained at all times. This construction renders the genera-tor particularly useful in connection with automobiles, as it is equally as ellicient as the ordinary lonT pressure generators for supplying the burners and as itI may be used in connection with acetylene starting devices, most of which require the acetylene to be under considerable pressure.
INhile a convenient embodiment of the invention is illustrated in 'the accompanying drawings, it will be understood that many changes may be made to the form and construction therein shown without departing from the spirit and scope of the invention as defined in the appended claims.
