ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 655,300, dated August 7, 1900f Application filed November 20, 1899. Serial No. 737,544. (No model.)

To all whom it may concern:

Be it known that I, ALFRnnC. EINSTEIN, a citizen of the United States,residing at the city of St. Louis, in the State'of Missouri, have invented a certain new and useful Improvement in Acetylene-Gas Generators,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class o f devices used in producing gas from carbids on the application of liquid thereto.

The object ot this invention is to produce a generator of the description named in which the quantity of liquid fed to thecarbid is controlled to a nicety, the quantity of liquid delivered being governed entirely by the pressure of the gas produced within the generator. Y

The drawing shows the generator-casing in vertical section and the liquid-feed tube mainly in elevation.

1 designates the generator-casing, provided in its upper part with a liquid-reservoir 2, having an inlet 3, closed by a cap 4.

5 designates the gas-chamber, in which the carbid A may be placed in any usual or convenient manner.

In the bottom of the reservoir 2 is a valveseat 6, that receives a valve 7 on a stem 8, that may be operated from the exterior of the generator to permit the flow of liquid from the reservoir into the liquid-feed tube 9. From the valve-seat 6 the feed-tube 9 extends down- Wardly to a point 10, from which it is bent upwardly in an uptake 11 and is provided with an outlet-nozzle 12. Beyond the 0utlet-nozzle 12 from the uptake portion 11 of the feedtube is a horizontal portion 13, into which the liquid may iiow, so as to occupy a position approximately on a plane with the orice in the outlet-nozzle 12. Extending vertically from the horizontal part 13 of the feed-tube is a pipe 14, that leads upwardly into the liquidreservoir 2 and is connected to a return-bend 15, to which is united a vertical pipe-leg 16, that extends downwardly and through the bottom of the reservoir into the gas-chamber 5.

17 designates an outlet-pipe leading from the gas-chamber and provided with a suitable valve 18. On the uptake portion of the liquidfeed tube is a guard or washer 11, located in proximity to the outlet-nozzle 12, this guard or Washer being designed to receive the flow' of liquid as itdischarges from the outlet-nozzle, so that the liquid is caused to fall in a central location onto the carbid instead of flowing down the tube to the point 10, from which it would discharge away froni the center of the body of carbid.

In the practical use of this generator the carbid A is placed within the generator, and the reservoir 2 being filled with liquid the liquid is permitted to liow into the feed-tube 9 from said reservoir. The liquid ows to the outlet-nozzle 12 and discharges therefrom to `the gas-chamber such pressure acts against the free discharge of liquid through the outlet-nozzle, and it is only through pressure exerted within the feed-tube to counteract the exterior pressure against the outlet-nozzle that the liquid is caused to flow 'through said outlet-nozzle. The pressure within the feedtube is obtained by the gas passing from the gas chamber into the vertical pipe -leg through the return-bend 15 into the vertical pipe 14 and downwardly to the horizontal part 13 of the feed-tube, as by this arrangement the pressure acts against the liquid that has flowed into said horizontal part of the feed-tube, and thereby equalizes the pressures exterior and interior of the feed-tube,

.so that the liquid may discharge uniformly.

The provision of the horizontal part 13 of the feed-tube comprises the essential feature of the invention herein described in that by the use of such part lying in a plane with the outlet-nozzle the liquid is maintained in the part named on a level with the liquid rising into the outlet-nozzle, and hence the liquid is not conveyed to the outlet-nozzle from said horizontal part by the force of gravitation, but is controlled entirely by the gas-pressure exerted within the generator, and as a result the amount of liquid delivered to the carbid is dependent upon the gas-pressure, to force it from the feed-tube, and as the pressures interior and exterior of the feed-tube must equalize there is no liability of an excess of liquid being fed to the carbid.

In the event of an excess of gas being gen- IOO erated in the gas-chamber 5 the gas passes therefrom through the pipe-leg 16 and thence to the horizontal portion 13 of the feed-tube,

which excessive pressure causes the liquid tobe forced backwardly or downwardly through the uptake 11 and to the liquidreservior. This results in the liquid being conveyed away from the outlet-nozzle, and consequently there is obviated any liability of an excess of liquid being discharged to the carbid to produce a surplusage of gas. As soon as the gas-pressure again becomes normal the liquid is permitted to return to the outlet-nozzle and the generating process is resumed.

I claim as my iuvention- 1. In a gas-generator, the combination of a carbid-container, a gas-chamber therein, a liquid -reservoir, a liquid-feed tube leading from said reservoir and having an uptake, an

part located beyond said nozzle and providedv with communication With said gas-chamber; substantially as described.

2. In a gas-generator, the combination of a carb'idcontainer, the gas-chamber therein, a liquid-reservoir, a liquid-feed tube leading from said reservoir and having an uptake, an outlet-nozzle projecting upwardly from said uptake, said feed-tube having a horizontal part located beyond said nozzle and provided With communication With said gas-chamber, and a guard located on said uptake; substantially as described.
