ACETYLEN E-GAS G EN ERATOR.

SPECIFICATION forming part of Letters Patent No. 610,306, dated September 6, 1898.

Application filed September 14, 1897- Serial No. 651,672. (No model.) I

To all whom, it may concern:

Be it known that I, \VILLIAM A. MCCUNE, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements inAcetylene-Gas Generators 5 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the figures of reference marked thereon, which forms a part of this specification.

My invention relatesto acetylene-gas generators, and pertains more especially to that class wherein the process of generation is carried on automatically, the main objects of my device being to furnish novel and simple means for replenishing the carbid without permitting an escape of the gas from the gasholder and a simple and new method of admitting the water to the carbid While in operation and cutting off the supply thereof.

In the drawing the figure is a vertical crosssection of my invention.

1 represents the usual water-tank, and 2 the gas-holder telescoping vertically therein. In the center of the gas-holder 2 and integral therewith is the cylinder 3, communicating with the gas-holder 2 by means of one or more holes 4t in said cylinder and pipes 5, secured therein, said holes 4 being a short distance below the Water-line when the gas-holder is at its lowest point.

6 is a lid or cover tightly secured upon the cylinderS by any known method. Suspended from the lid dwithin the cylinder 3 is the carbid holder or pail 7, having -a tight bottom and sides except where perforated by one or more series of minute holes 8 immediately below the Water-line when the gas-holder 2 is at the lowest point.

By means of the pipe 9 the gas is conducted to the usual gas-reservoir or gasometer (not shown) and prevented from-returning when desired by the shut-off cock 10. Through the funnel l1 and aperture 12 in the wall of the water-tank 1 the Water can be kept at the desired height in such tank.

In operation the pail 7 is partly filled with calcium carbid, inserted within the cylinder 3, and the cover 6 secured in place. The wa ter immediately enters the holes 8 and, coming in contact with the carbid, generation of acetylene gas results. As the gas fills the cylinder 3 it'is not sufficient in quantity to raise the gas-holder 2; but the pressure of "the gas forces the water surrounding the carbid-holder 7 downward until the gas escapes through the opening 4 and pipe 5 into the gas-holder-2. 'As the gas-holder becomes charged with gas it rises, carrying with it the cylinder 3 and pail 7, until the perforations 8 are abovethe water-line and the supply of water to the carbid shut off. As the supply of gas becomes depleted and the Water in the carbid-pail is exhausted the gas-holder descends until fresh water is supplied, and the process continues. The perforations 8 are quite small, so as to have the eifect of a spray, and it is not necessary to use more than the lower hole 8 of the series, the additional holes merely increasing the rapidity of generation, which can also be regulated by the size of one or more of the lower holes used alone.

In cleaning out the pail 7 and renewing the carbid (which can only be done when the gasholder 2 is at its lowest point) the gas is con fined in the gasometer by means of the stopcock 10, it being impossible for what gas there may be in the gas-holder 2 to escape, on account of the opening 4 being below the water-line. The greater volume of gas is in the gasometer, the gas-holder of which, having no attachments, is lighter and rises more easily than the gas-holder 2.

It is evident that as soon as the opening t is elevated above the water-line there is direct communication between the cylinder 3 and gas-holder 2.

If desired, the opening 4 in the cylinder 3 can be used without the tubeor pipe 5; but in such use, while the hole 4 is below the Wa= ter-1ine, the gas in escaping through the water on the outside of the cylinder would make a continual bubbling noise, which is averted by the use of the pipe.

What I claim as my invention, and desire I to secure by Letters Patent of the United States, is-- 1. In a gas-generator, the combination with a vertically-operating gas-holder provided with a pendent inner generating cylinder open at'both' ends, and having a series of ap ertnres through its walls normally below the:

water-level, of pipes extending npwardlyfrom said apertures to a point above the Waterlevel, a cover designed to close the upper end: 7

of the cylinder, and an apertured carbidholder suspendedwithin said cylinder, substantially as specified: r V V 2. The combination with a water-tank providediwith a supply-funnel upon its exterior and below its upper edge, of a gas-holder within the tank provided with an inner pendent generating-cylinder opening thronghthe top of the gas-holder and providedwith apertures normally in a lower plane than the bottom of the supply-f unn'el, pipes communieating at their lower ends with said apertures and extending upwardly close to the exterior 1 r V of the cylinder, a cover above the gas-holder and closing the upperend of the generatingcylinder, a carhid holder suspended within 7 the cylinderlfrom the cover and provided with a ClOSQClbOElZOHlHHd aperturesadjacent to the apertures in the cylinder and a cock-com trolled gas-pipe piercing the tank at its bottom and extending upwardly intozthe gasholder to a point above the water-level, sub

stantially as specified. V r V r In testimonywhereof I aliix my signature in presence of two Witnesses.
