- a suitable screw-cap is preferably provided for the introduction of fresh water into the tank when required.
- One or more bars m are preferably placed across the machine below the cylinder 70 to support it when being slid into place.
- the operation of the generator is substantially as follows:
- the cover f is taken off and the cylinder 70 removed from the machine.
- the cover Z is then removed and a quantity of carbid placed in the cylinder.
- the cylinder is slid into place again, the shape of the bearing-piece p facilitating the entrance of the pivot it into its proper place. If the spring-actuated pin q does not at once fit the hole '1', it will drop into one as soon as the bearing-piece p is rotated, as hereinafter described.
- the cover f is then replaced, the pivot 0 rising into position in the manner similar to pivot 12. After the cover fisclamped into place the water may be turned on, and a fine spray of water will then fall upon the carbid in the cylinder.
- I provide the bearingpiece 19 with a ratchet-wheel n, located outside the casting Z). With this ratchet-wheel a pawl 0 engages. a disk at the end of the spindle 19, carried in a gas-tight bearing and provided with a suitable crank-handle or hand-wheel. By this connection a rotary motion may be imparted to the cylinder at any time without reference to the automatic mechanism for operating the same.
- the gas passing intermittently through the piston cl escapes through the exit-pipe C, which is preferably provided with a check or cut-off valve, as indicated in Fig. 1. It should be mentioned that a gauze diaphragm may be placed in this pipe between the generator and the holder as a safety measure and also at any other points where experience shows it to be advisable.
- Access may be had to thelower part of the generator to remove the lime dropped through the perforations of the cylinder by removing the cover 6.
- a bridge t Connected to the side of the holder is what is termed a bridge t, formed with upper and lower inclined surfaces.
- a spindle o Sliding in a suitable air-tight guide a is a spindle o, having journaled at its inner end the wheel a, normally pressed inward in the path of the bridge t by means of the coil-spring I) pressing against a pin on the spindle and the guide u.
- the outer end of this spindle is pivoted to the lever c, which itself is pivoted at its upper end to the standard d. The lower end.
- This pawl is pivoted on w the gas-holder descends the spindle v is pushed outwardly, which outward motion is by-the connections described transmitted to the lever on the spindle of the valve g and the water-supply gradually turned on; As the holder rises the spring 17 returns the spindle to its original position, and thewatersupply is thus cut off again.
- the supply of water depends, of course, the rate of production of acetylene, and thus the production of the gas is controlled automatically, so as to maintain a practically unvarying supply in the holder.
- the gas-holder will continue to descend till the highest part of the bridge thas passed the spindle '0.
- the 7c is a spindle similarly mounted and provided with a wheel'and coil-spring, 'such as provided for the spindle o.
- the outer end of this spindle has a central, plate connected thereto, which when the spindle is moved outwardly forms a connection between the springs Z, to which may be connected the wires of an electric-bell circuit. ⁇ Vhen the bridge 25 falls low enough to push out the spindle 7c and thus complete the contact between the springs Z, the bell-circuit is closed and warning given that the gas is becoming exhausted from the generator.
- an opening or openings m In the top of the holder G is formed an opening or openings m. (See Figs. 1 and 5.) These openings are closed by the valve n, the spindle of which extends upwardly through the central hole shown in Fig. 5. A coilspring is placed on the spindle of the valve bearing against the top of the holder and a head formed on the said spindle. If the generation of gas is not stopped by the closing of the water-supply and the holder G rises too far, the head formed on the spindle of the valve n comes in contact with the top of the closed cover F, and the valve is pressed downward, thus affording an exit for the surplus gas. This gas may escape through the outlet-pipe V.
- the top of the holder are placed a series of studs 0 on which may be placed weights to regulate the pressure upon the gas now in the holder.
- a cord 1 is connected to the holder G.
- This cord passes out through a small hole in the top of the closed cover F over a pulley q, connected to the top thereof, thence down under a pulley 0', connected to the board 8, and thence up and over a pulley 15, connected to the top of the said board.
- a weight or indicator to is connected to the end of this cord, which thus serves to indicate at all times the exact position of the holder G.
- the board 8 is suitably supported from the closed cover F.
- the points of my invention which I consider particularly important are the use of a rotatable cylinder in the generator to contain the carbid operated upon by the Water-spray, so that the lime formed by the decomposition of the calcium carbid is shaken from the lumps of carbid by the rotation of the cylinder and dropped through the perforations to the bottom of the generator, thus leaving new surfaces of carbid to be acted upon by the water-spray; the use of automatic means for causing the revolution of the perforated cylinder, the use of a condenser located within the water-tank of the storage apparatus which serves to deprive the gas of its surplus moisture and also reduces the weight of water required; providing the gas-holder with a closed cover provided with a pipe, so that all gas escaping either by leakage or in the operation of the relief-valve at the top of the holder may be conveyed to a place where its odor will cause no annoyance; providing the water-regulatin g apparatus with means for turning the water off when the supply of calcium carbid

ber 14, 1896, under No. 53,766, and in Great Britain on October 12, 1897, under No. 22,628, and applied for Letters Patent in Germany on -November 16, 1896, under No. K. B. 23,923,)
of which the following is a full, clear, and exact description.
The object of my invention is to devise an automatic apparatus for the production and storage of acetylene gas which will be efficient, economical, and safe; and itconsists, essentially, of a generator in which the decomposition of the calcium carbid is effected in a rotatable perforated oropen-work cylinder, by the rotation of which the lime is shaken from the surface of the carbid, of a condenser located in the water-tank of the gas-holder, of automatic apparatus for regulating the water-supply and for closing it 01f when the gas-supply to the holder ceases, and in such other improvements as are hereinafter more particularly described and then definitely claimed.
Figure 1 is a sectional view of the whole apparatus. Fig. 2 is a sectional detail of the generator. Fig. 3 is an enlarged detail in elevation of a portion of the carbid-cylinder-rotating mechanism. Fig. A is a plan view of half the diaphragm in the condenser. Fig. 5 is a plan view of the valve-opening in the top of the gas-holder.
In the drawings like letters of reference indicate corresponding parts in the different figures.
In Fig. 1, A is the generator, hereinafter more particularly described, and O the gasexit pipe leading from the top of the generator.
D is the gas-storage apparatus, consisting of the tank E, the closed cover F, and the holder G, the lower end of which is open and is immersed in the water in the tank E in the usual manner.
A is a funnel connected by a pipe 13, provided with a suitable stop-cock, with the interior of the tank E. By means of this fun- .nel water may be introduced into the tank as becomes necessary, the funnel being preferably so proportioned that its upper surface represents the usual level of the water within the tank.
The holder G is provided with a suitable number of guide-wheels H, running on guides I on the inside of the closed cover F.
Located in the tank E is the condenser J, which serves the double purpose of condensing moisture contained in the gas and of reducing the quantity of water contained in the tank E. The gas-eXit pipe 0 from the generator enters the bottom of the condenser belowthe center of the diaphragm K, which is provided with a series of openings around its outer edge. Thus the gas entering the condenser from the pipe 0 strikes the center of the diaphragm and is deflected byit, so as to be compelled to pass upward in contact'with the sides of the condenser. These being cooled by the water in the tank E condense the major part of the moisture contained in the gas. The moisture thus condensed runs down to the pipe 0 and into the Water sealL, which is provided with the overflow-pipe M. Thus the condensed moisture running into the seal is allowed to overflow without permitting the escape of gas. Situated at the top of the condenser is a valve N, which closes an opening formed in the top of the condenser or of atube 0, connected thereto. The stem of this valve is steadied by a skeleton guide P, which is shaped so as to permit of the free passage of gas. This valve permits of the escape of the gas in the condenser in a series of puffs, but will close to prevent any backflow taking place.
Q is the gas-exit pipe from the holder. This pipe passes down through the water in the tank, its upper end being located above the level of the same. After passing through the bottom of the tank the pipe is turned horizontally and then upward again. At the elbow is located the plug R, which may be withdrawn when desired to clear the pipe of any condensed water. Above the plug is located the safety-chamber S. This chamber has a quantity of loose asbestos or crushed pumice therein, held between two gauze dia phragms T. The purpose of this chamber is to prevent the flame running down the pipe to the holder from any of the burners in the event of a mixture of air and gas being present at any time in the pipe or holder. The gauze diaphragms would probably be sufficient, but the asbestos is an additional precaution. Above the safety-chamber S the pipe is bent downward again and the cap U placed on its end, by the removal of which collected moisture may be withdrawn from the pipe. Above this cap the connection with the pipe leading to the burners is formed.
Connected to the top of the closed cover F is an outlet-pipe V, which serves to permit of the egress and ingress of the air as the holder G rises and falls. To avoid accidents occurring through an explosive mixture of air and gas formed within the closed cover, a gauze diaphragm a is placed. in this pipe.
0n reference to Fig. 2 the construction of the generator A will be readily understood. The body of the generator is preferably made of galvanized sheet-iron in the form indicated. The ends of the generator are preferably formed of castings b and c, the casting e being preferably flanged to receive the circular covers e and f, an air-tight joint being insured by the use of the rubber packing g between the covers and the casting. The covers are held in place by means of the eccentrics it, formed on spindles 'L, which are held by the hooks j, formed on or connected to the casting 0. By revolving these spindles the covers e and f may be clamped tightly against the casting c. v
k is a cylinder constructed of wire-netting, perforated sheet metal, or a grating of bars. Z is a flanged cover fitting within the end of the cylinder k and bearing against the lugs 7n, formed thereon. These lugs also form a connecting-point for the longitudinal brace-rods connecting the ends of the cylinder. A pivot 02 is connected to the end of the cylinder and a pivot o to the cover. The pivot 0 has its bearing in a projection on the inside of the cover f, which is preferably formed with a cone-shaped opening to guide the pivot into its proper place when the cylinder is put in position. The pivot 02 has its bearing in a bearing-piece p, which is similarly shaped to the projection on the inside of the cover f. This bearing-piece p is suitablyjournaled in the casting b and is provided with a springoperated pin q, adapted to engage with any one of a series of holes 0, formed in the end of the cylinder 7r. Journaled on the bearingpiece 17 is a lever s, 011 which is pivoted a pawl 15'', adapted to engage with the ratchet-teeth a, formed on the bearing-piece 19. (See Fig. b is a pawl pivoted on the casting?) and vi is a finger connected to the upper end of the cylinder e and so placed that if the piston d" rises above its normal limit the finger will come in contact with the valve f through the central opening in the piston and force it open, thus permitting of an escape of gas.
0 is the exit-pipe from the generator, which is connected, as previously described, to the gas-holder.
j is the water-tank, which is connected with the spray-pipe 70', located within the generator and above the cylinder 70. The connection between the tank and the spray-pipe is provided with a valve g, to the spindle of which is connected a lever f ,operated as hereinafter described. (See Fig. 1.)
Z is a pipe connecting the generator with the space above the water-level in the tank, so that the pressure above the wateris maintained at the same point as the pressure in the generator into which it is introduced. A suitable screw-cap is preferably provided for the introduction of fresh water into the tank when required.
One or more bars m are preferably placed across the machine below the cylinder 70 to support it when being slid into place.
The operation of the generator is substantially as follows: The cover f is taken off and the cylinder 70 removed from the machine. The cover Z is then removed and a quantity of carbid placed in the cylinder. After replacing the cover the cylinder is slid into place again, the shape of the bearing-piece p facilitating the entrance of the pivot it into its proper place. If the spring-actuated pin q does not at once fit the hole '1', it will drop into one as soon as the bearing-piece p is rotated, as hereinafter described. The cover f is then replaced, the pivot 0 rising into position in the manner similar to pivot 12. After the cover fisclamped into place the water may be turned on, and a fine spray of water will then fall upon the carbid in the cylinder. As the gas is generated it gradually lifts the piston 01", the central opening in which is closed by the valve f. As the piston rises the spring on the rod g is gradually compressed till finally the valve will rise no further and the piston is lifted away from it, the gas escaping through the opening in the piston. As soon as the valve is removed the slightest distance from its seat, so as to allow of the passage of gas, the spring on the rod g will immediately draw the valve down to its lowest point, preventing the valve again closing till the escape of gas has permitted the piston to drop, when the valve again seats itself and the piston will begin to rise once more. As the motion of the piston is communicated by the connecting-rod c to the lever s and pawl t the latter will revolve the bearing-piece p a short distance every time the piston rises, the dog I)" preventing the bearing-piece from going back when the lever 8 and its connections again drop. As the bearing-piece is connected with the end of the cylinder is, as previously described, the rise and fall of the piston d imparts an intermittent rotary motion to the cylinder 75, thus effectually turning over the carbid in the cylinder. The lime formed by the decomposition of the carbid is thus shaken off and drops through the meshes of the cylinder, leaving fresh surfaces of carbid to be acted upon by the water spray.
As it may sometimes be desirable to revolv the cylinder by hand, I provide the bearingpiece 19 with a ratchet-wheel n, located outside the casting Z). With this ratchet-wheel a pawl 0 engages. a disk at the end of the spindle 19, carried in a gas-tight bearing and provided with a suitable crank-handle or hand-wheel. By this connection a rotary motion may be imparted to the cylinder at any time without reference to the automatic mechanism for operating the same. The gas passing intermittently through the piston cl escapes through the exit-pipe C, which is preferably provided with a check or cut-off valve, as indicated in Fig. 1. It should be mentioned that a gauze diaphragm may be placed in this pipe between the generator and the holder as a safety measure and also at any other points where experience shows it to be advisable.
Access may be had to thelower part of the generator to remove the lime dropped through the perforations of the cylinder by removing the cover 6.
Although I describe a specific mode of construction of the cylinder e" and piston 61 for revolving the carbidcylinder it, yet any other device which would intermittently rotate the carbid-cylinder by the action of the gas generated would answer the purpose of my invention, or if the apparatus is placed in a position where an attendant is always on hand thehand-operated rotating device would prove sufficient.
It will now be necessary to describe the apparatus for controlling the water-supply and through it the generation of the gas.
Connected to the side of the holder is what is termed a bridge t, formed with upper and lower inclined surfaces. Sliding in a suitable air-tight guide a is a spindle o, having journaled at its inner end the wheel a, normally pressed inward in the path of the bridge t by means of the coil-spring I) pressing against a pin on the spindle and the guide u. The outer end of this spindle is pivoted to the lever c, which itself is pivoted at its upper end to the standard d. The lower end.
This pawl is pivoted on w the gas-holder descends the spindle v is pushed outwardly, which outward motion is by-the connections described transmitted to the lever on the spindle of the valve g and the water-supply gradually turned on; As the holder rises the spring 17 returns the spindle to its original position, and thewatersupply is thus cut off again. Upon the supply of water depends, of course, the rate of production of acetylene, and thus the production of the gas is controlled automatically, so as to maintain a practically unvarying supply in the holder. When the carbid becomes exhausted, the gas-holder will continue to descend till the highest part of the bridge thas passed the spindle '0. As the holder continues to descend the inclined upper surface of the bridge permits the spindle to move in again, and the water-supply is again out off, thus avoiding waste during the interval between the exhaustion of the generator and the introduction of. a fresh supply of carbid therein. As it is necessary to maintain a good supply of water when first setting the apparatus in action, I provide ahook h, pivoted on the standard 2". The notch of this hook may be engaged with a pin j, and the length of the hook is so proportioned that when spindle o are moved outwardly and the hook,
thus released, falls to the position indicated in the drawings, further downward motion being prevented by the stop indicated at its pivot-point.
7c is a spindle similarly mounted and provided with a wheel'and coil-spring, 'such as provided for the spindle o. The outer end of this spindle has a central, plate connected thereto, which when the spindle is moved outwardly forms a connection between the springs Z, to which may be connected the wires of an electric-bell circuit. \Vhen the bridge 25 falls low enough to push out the spindle 7c and thus complete the contact between the springs Z, the bell-circuit is closed and warning given that the gas is becoming exhausted from the generator.
In the top of the holder G is formed an opening or openings m. (See Figs. 1 and 5.) These openings are closed by the valve n, the spindle of which extends upwardly through the central hole shown in Fig. 5. A coilspring is placed on the spindle of the valve bearing against the top of the holder and a head formed on the said spindle. If the generation of gas is not stopped by the closing of the water-supply and the holder G rises too far, the head formed on the spindle of the valve n comes in contact with the top of the closed cover F, and the valve is pressed downward, thus affording an exit for the surplus gas. This gas may escape through the outlet-pipe V.
0n the top of the holder are placed a series of studs 0 on which may be placed weights to regulate the pressure upon the gas now in the holder.
In Fig. 1 it will be seen that a cord 1) is connected to the holder G. This cord passes out through a small hole in the top of the closed cover F over a pulley q, connected to the top thereof, thence down under a pulley 0', connected to the board 8, and thence up and over a pulley 15, connected to the top of the said board. A weight or indicator to is connected to the end of this cord, which thus serves to indicate at all times the exact position of the holder G. The board 8 is suitably supported from the closed cover F.
The points of my invention which I consider particularly important are the use of a rotatable cylinder in the generator to contain the carbid operated upon by the Water-spray, so that the lime formed by the decomposition of the calcium carbid is shaken from the lumps of carbid by the rotation of the cylinder and dropped through the perforations to the bottom of the generator, thus leaving new surfaces of carbid to be acted upon by the water-spray; the use of automatic means for causing the revolution of the perforated cylinder, the use of a condenser located within the water-tank of the storage apparatus which serves to deprive the gas of its surplus moisture and also reduces the weight of water required; providing the gas-holder with a closed cover provided with a pipe, so that all gas escaping either by leakage or in the operation of the relief-valve at the top of the holder may be conveyed to a place where its odor will cause no annoyance; providing the water-regulatin g apparatus with means for turning the water off when the supply of calcium carbid in the generator is exhausted, as well as for automatically regulating the generation of gas under ordinary circumstances, and also in the various details of construction set out in the claims forming a part of this specification.
- It will of course be understood that the construction shown may in many cases be varied considerably without departing from the spirit of my invention.
