MYER GOLDSIEIN, OF JCHANNESBURG, TRANSVAAL.

ACETYLEN E-GAS GENERATOR'.

T @ZZ whom t may concern/.1

Be it known that I, MYER GoLDsTErN, a

citizen of the United States, residing at .Io-

vwith an external bead or rim a.

hannesburg, Transvaal, have invented cer-` tain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

'lhis invention relates to acetylene-gas genera-tors and lamps.

It is designed With the object of producing a generator which may be made in. different sizes either for large or small lighting installations or as a street, table, or hand lamp for domestic, mining, or other purposes.

A generator or lamp constructed in accordance with my invention is of extremely simple, compact, and efiicient construction and is adapted to receive, if desired, a large charge of calcium carbid. Further, it is very readily taken apart to clean it or toremove the spent calcium-carbid charge and renew it when necessary. The volume or quantity of gas generated is automatically regulated by the demand or quantity consumed. The internal pressure set up when the quantity of gas generated exceeds the demand operates a valve which shuts off the water-supply.

The construction and arrangement of a generator and lamp embodying my invention is illustrated in the accompanying drawing, forming part of this specification, and I will now proceedto describe the same in detail by aid thereof.

The drawing represents a sectional elevation ofa generator and lamp designed more particularly for miners use. It is adapted to be carried in the hand or to be suspended in the undergroundworkings of a mine.

In the drawing, A represents an outer cylindrical or other suitably-shaped vessel which constitutes the water-holder of the generator. The outer cylinder A is closed at the bottom a and at the` upper end is formed To the outside and at the top of the cylinder A are soldered, riveted, or otherwise suitably fixed brackets a2, to which is attached the handle B. Inthe case of a portable lamp the handle B serves as a convenient means for suspending the lamp; but it will be evident that the handle may be fixed to the side of the cylinder A or in any other convenient position. In the case of a stationary generator the handle B would be dispensed with', and in the case Specification of Letters Patent.

of a table orother similar lamp they cylinder A may form part of or be arranged inside an ornamental stand or base. Inside 'the cylinder A is arrangedi another and: preferablr concentric cylinder C, which. constitutes; the holder for the calcium carbid. The cylinder C is closed at the bottom cv and at the upper ehnd` is constructed with the external bead or rim c.

Arranged inside the calcium-carbid holder C is the vertically-disposed pipel D. The pipe Dis rigidly fixed by means of the conical piece ofinetal d or otherwise to the bottom c of the cylinder C. The pipe- D is closed at the bottom and at its upper end projects for some distanceabove the levely of the top of the cylinder C. At its upper extremity it is formed with an external screwthread d. The pipe D, which serves for taking off the gas from the interior of thecylinder C, is constructed with one or more holes d2, forming inlets intothe pipe D.I

The calcium-carbid holder C is closed by means of a cover E, consisting of the topand bottom concavo-convex plates e e. rIlhe cover E is constructed' round the rim e2 with a recess e3, formed between the flangeor The bottom plate e is sol-I the rim e2 of the cover E, is placed'a packingi ring of rubber or other suitable resilient material which serves for making a gas-tight joint with the bead, rim, or upper edge c of the calcium-carbid holder C.

The vertical pipe D projects through the cover E, and the latter isconstructed toi-form a recess d3 round the pipe D, whichv recess communicates with the interior of the cylinder C and through the hole or holes d2 with the interior of said pipe ID. The recess d3 serves as the passage along which the gas iiows out of the cylinder C through the hole or holes d2 of the pipe D.. r

Round the upper end of the vertical pipe D and above the top of the-cover E is placed a metal washerf, and over the metal washerf a washerf, of leather or other suitable material, which makes a gas-tight joint between the cp)ver E andthe upper end of the vertical i e p l:Cver the externally-screwedfupper extrem- IOO IOC

elbow-piece H, into which is screwed a pipe J, which serves as the outlet for the gas. On the outer extremity of the pipe J is screwed a tap K, to which is xed the. burner L. The

gas entering the vertical pipe D through the hole or holes d2 is free to pass through the socket F, nipple G, and elbow-piece H to the pipe J and from the latter through the tap K to the burner L.

A coverM is iit-ted into the upper end of the external cylinder A. This cover coinprises the top and bottom concavo-convex plates m m', which are soldered or otherwise connected at the rim' m2. The top plate m is constructed to project over the top of the bead or rim a. of the cylinder A, and the bottom plate m is turned downward to form an inner ring ma, which fits the upper end of the cylinder The upper end of the so'cket F projects through a hole at the center of the bottom plate m, to which it may be soldered or otherwise attached.v The elbow-piece H is located between the top and bottom plates m m of the cover, and the gas outlet pipe J passes through a hole in the top plate m, to which 1t may be soldered or otherwise suitably conneet-ed, In this manner the socket F, nipple o G1 elbow-piece H, gas-outlet pipe J, tap K,

and burner are all attached to the cover M for the outer cylinder A. A handle N is attached to the top plate m of the cover M, which serves for removing said cover and with it the calcium-carbid holder Cfrom the water or external cylinder A.

At or in proximity t-o the top or upper edge ofthe cylinder C is attached the device which serves for controlling the admission of the This consists of a casing O, to which is attached a pipe o, which serves for conducting the water into said casing. The pipe o is preferably bent up for a suitable distance at the bottom. The casing O is formed with a screwthreaded hole, through which is screwed a valve or screw o', which serves for closing or adjusting the area ofthe opening forming the inlet for the water in the casing O. Into the casing O on the inside of the cylinder C is screwed a cylindrical piece o2, in which is fitted a tubular piece o3. The tubular piece o3 communicates at one end with the interior of the casing O and at the other end with a space o4, formed between it and the end of the cylindrical piece c2. ln this space o4 is placed a ball-valve o5, which has a seating provided for it in the end of the tubular piece o3 round the hole communicating with the casing O. A hole o6 is formed in the end of the cylindrical piece o2, and a number of small holes o7 are formed round the end of said cylindrical piece o2, which permit the water which passes from pipe o, casing O, tubular piece o3 into the space o4 to pass from said space into the calcium-carbid holder C.

To remove the spent charge from the calcium-carbid cylinder C, the cover M of the water-holder-A is raised, which lifts with it the cylinder C. The cylinder C is then detached from the cover M by screwing the upper end of the vertical pipe D out of the lower end of the socket F. This allows the leather and metal washers ff and the cover E of the cylinder C to be removed. The spent charge is then removed from the cylinder C and the cylinder washed out and a fresh charge inserted. The upper end of the vertical pipe D is then screwed back into the socket F, and after turning the valve or screw 0 to open the water-inlet into the casing O the water-holder A is partially filled with water. y The calcium-carbid holder is then lowered into the water-container A and the cover M fitted in position in said container A.

Sufficient water 'is placed in the waterholder A for the level to rise above the level of the inlet controlled by the valve o5. The tank or cylinder A is preferably nearly illed. When the cylinder C has been placed in position in the water-container A, the water is then free to pass by the pipe o into the casing O and along the hole in the tubular piece o3 and to enter the calcium-carbid holder C by the holes o7 in the cylindrical piece o2, whereupon the acetylene gas is evolved. The gas then passes into the recess d3 in the cover E and hole or holes d2 in the vertical pipe D to the interior of said pipe and from the latter through the socket F, nipple G, and elbowpiece H to the pipe J, and from the latter under the control of the tap K to the burner L. In the event of too large a quantity of the gas being generated it forces the ball-valve 05 onto its seat in the end of the tubular piece o3 and so closes the hole and prevents any more water entering the carbid-container until the pressure falls, and thus the quantity of gas generated is automatically regulated.

To put the lamp out of operation, the carbid-holder C is removed from the vessel A and the valve or screw o screwed down onto its seating in the end of the pipe o, which prevents the admission of any more water to the vessel C when the latter is placed back in the vessel A. It will also be evident that the valve or screw owill serve as a means for regulating or controlling the admission of the IOO IIO
