ACETYLENE-GAS GENERATOR.

Application filed April 7,

To all whom it may concern:

Be it known that I, DAY'roN'HnRscHm DAN-LE1, a citizen of the United States, residing at La Fayette, in thecounty of Tippecanoe and State of Indiana, have 1nvented new and useful Improvements in Acetylcnc-Gas Generators, of which the This invention relates to acetylene gas generators and has for its object the provision of a generator so constructed and arranged as to be automatically self adjustin in thc matt-erof pressure so that uniform flow at a certain predetermined pressure may be had. 0

Another pbject is the provision of a genorator provided with means whereby the generationjnav be accelerated, retarded or I cutoii at will with the utmost ase.

eral improvement in the-art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure l is a side elevation of the device partly broken away and in section,

Figure 2 is a top plan View,

Figure 3' is a central longitudinal section.

Figure 4 is a cross section on the line 4-4 of Figure 1,

Figure 5 is a cross section on the line 5-5 of Figure 3,

F igure 6 is a plan view of the magazine (U\'f l'.

Referring more part cularly to the drawings the numeral 10 designates an upright elongated tank of suitable size and'shape, the size depending of course on the character of the work in which the generator is to be used. \Vithin this tank and projec'tin'g considerabliy 19 4. Serial m. 704,834.

above the top thereof 15 a. shell 11 forme near its upper end with an inwardly extending ledge 12 for a purpose to be'described. The top of the tank 10 is connectedwith the shell ll-by a wall 13 in which is located a. vent valve 14 for a purpose to be described. The lower end of the shell 11 extends considerably down into the tank 10 and is flared outwardly as indicated at 15. The t nk 10 is designed to contain water to theilevel indicated by the line 16 and at this le valve 17 so that afterithe tank is filled with water it me be permitted to drain out to the proper evel as indicated, after which the valve 17 would of course be closed. At the very bottom of the tank is a drain valve 18 so that the water maybe drawn out when desired. The s ace 19 between the tank 10 and shell 11 is for the accumulation of the gas as it is generated.

Mounted at one side of the u per por tion of the shell is a filtering evice inel is provided a drain eluding an elongated casing 20 into the lovyer end of which leads 8. pi e 21 communicating with the interior 0? the shell, and'leading from the to of this casing is an outlet pipe 22 provi ed with a control valve 23. The filtering medium may conveniently be hair indicated at 2%, though it is obvious that some other material may be used if preferred. Interposed in the pipe '22 is a T 25 to which is connected a pip'"26 connected with the tank 10 at the wall 13 thereof and communicatng with the compartment 19. In'this pipe 26 is a control valve 27.

The numeral 28 represents an'elongated magazine which has a cage bottom 29 and which contains carbide cakes indicated at 30. This magazine is arranged within the shell 11 and is formed with an outstanding flange 31 which "rests upon the ledge 12.- The length of this magazine is such that the lowermost cake therein will be about ill) ioc

lates in the bottom of the tank,'I

and the cover 33 also removed so that the carbide holder or magazine 28 may be removed. The tank is filled with water to the level 16 and the magazine is filled with the carbide cakes 30. The magazine cover, plate and studs are then replaced. The valve 27 should be, closed and the valve 14 opened. The lowermost cake is wetted only slightly for the reason that the pressure of gas gen- 'erated almost instantly u on contact of the water with the cake wil force the water down entirely or at least partly out of the lower end 15 of the shell so that the generation will stop. The valve 14 is then closed and while the generation continues slightly there is only a small pressure- In order to start the generation to its proper extent so as to increase the pressure, the valve 27 should be opened. The pressure is then equalized inside and outside of the shell 11. The water rises in the shell until it reaches the level 16 and the lowermost cake is again subjected to the action of the water. The water level will remain at this oint until the valve 27 is closed. Upon cosing this valve, the generation will continue for an instant but is discontinued very shortly owing to the fact that the increased pressure within theshell again drives the water downwardly. T o obtain a flow of gas, the valve 23 is opened and the torch or other device using the gas is light-ed in order to ascertain whether or not the proper pressure is being furnished thereto. It the pressure is too high, it may be relieved by opening the valve 14 for an instant and if the pressure is too low, the valve 27 should be opened. As soon as the flame of the burning gas is of the proper length or v character, the valve 27 should be closed and means ing the crank 41 and draining of the whole device is effected through the valve 18.

While I have shown and described the preferred embodiment of my invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

I claim: I

In a device of the character described, an upright tank adapted to contain water formed with a neck portion of reduced diameter extending upwardly beyond the top to a considerable extent, said neck portion having a depending extension located within the tank, a magazine suspended within said neck and depending extensions in spaced relation to the walls thereof and adaptcd'to contain carbide in caked form, a closure member for said magazine, a cap for closing said neck and acting to retain the magazine closure in position, an elongated upstanding cylinder mounted beside the neck at the upper portion thereof and containing filter-- ing material, a pipe leading from the upper portion of said tank and provided with a control valve. an outlet valve connected with the top of said cylinder and with said pipe and an intake for said cylinder connected with the bottom thereof and connected with the lower portion of the neck to communicate with the space between the neck and the magazine.

In testimony whereof I-afiix my signature.

DAYTON HERSCHEL DANLEY.
