GAS-GENERATOR,
Specification of Letters Patent,
Patented May 5, 1914.
Application filed March 27, 1913. Serial No. 757,060.
To all wkom'z't may concern:
Be it known that I, Fninnnron KnAoss, a subject of the Emperor of Austria-Hungary, residing at Landwehrstrasse 39, Mu nich, Germany, have invented certain new and useful Improvements inv Gas-Generators, of which the following is a specification.
My invention relates to gas generators of the ebb and flow type, wherein a gas evolvin solid such ascalcium-carbid, held suspen ed in a foraminous pan, is adaptedto be decomposed by a suit-able liquid, where by gas such as acetylene gas is evolved.
The principal object of the invention is to provide in a gas generator, automatically operating means whereby the pressure of gas evolved in the generating chamber is maintained substantially constant with respect to a predetermined pressure normal or standard. I
A further object of the invention is to pro- I vide a structure wherein the gas in the generating chamber itself cotiperates in the maintenance of the predetermined pressure standard.
A further object of the invention is to so arrange the device that the rate of gas evolution and the pressure thereof, will be automatically accommodated to the gas consumption.
A structure embodying my invention, includes a gas generating chamber, a pressure regulating chamber, and means whereby communication between the ,two chamhers is established or closed.
I have illustratively exemplified the preferred form of the invention in the accompanying drawing, wherein the figure is a vertical sectional view of a gas generator embodying the several features of my invention. I
Referring to the accompanying drawing by characters of reference, 1 designates ,a container or vessel of any suitable construction; designed to be tightly closed by the cover 1' through the medium of the winged nuts 3 and 4. Suspended within the vessel 1 is a hell 2, the latter being firmly secured to the cover 1 by means of the service pipe 15 provided with the controlling valve 16.
The interior of the bell constitutes the gas generating chamber 10 and the interior of the casing 1 surrounding the bell constitutes the pressure regulating chamber 11 all as more fully hereinafter described. The
to afford communication between the chamber 10 and the chamber 11, which latter in addition to serving as a pressure regulating chamber, is also designed to receive the liquid which decomposes the solid 8 for the p rpose of gas generation.
The cover 1 of the receptacle 1 is provided with a. centrally bored boss 24 to which is attached a housing 25 in which a flexible diaphragm 19 is centrally clamped. Superimposed on the housing 25 is a centrally bored block 26, the upper face of which carries a scale 23,. graduated to any standard which. may-,be'determined em pirically. Extending through the central bore of the block 26 is a screw 21 carrying near its upperend an index or pointer 22 adapted to be moved over the scale 23, said index being secured to the screw by the nut 28. The block 26 is internally threaded to correspond ,with the threads of the screw 21.
The lower end of the screw 21 is smooth and reduced in diameter, and is encircled by one end of a helical spring 20, the other end 'of' said spring contacting with the diaphagm 19 at approximately its central part. Contacting with the diaphragm 19 opposite the spring 20, is the enlarged end of a rod 18 which passes through the boss 24, and througha vertical bore 27 in the .block 9, and carries at its lower end a preferably conical valve 13 adapted to engage the seat 9? formed in the lower faceof the block 9. As clearly shown in the drawing, the lower end of the duct '12 is substantially in line with the lower end of the bore 27, so that the valve 13 serves to control both passages. I
The operation of the invention will be understood from the following description thereof: A suitable liquid is introduced into the container 1, to approximately the level of the line XX. The bell 2 is then inserted whereby the liquid will be displaced and caused to rise to approximately the height illustrated in the drawing. The cover 1 carrying-the bell 2 is then tightly clamped on the receptacle 1 by the nuts 3 and 4, it being assumed level, of liquid in the belll2 will be caused toof course, that the valve rod 18 and its appurtenant parts have been installed in position. The index 22 is then moved over phragm to a corresponding degree. Theflexure of the diaphragm also results in unseating the valve 13 to a degree corresponding with the desired predetermined pressure. The interior of the chamber 11 being open to the diaphragm 19 through the bored boss, 24, the airin chamber 11 will be free to act against the diaphragm.
As the liquid in chamber 11 passes up through the bottom of the bell .2, it contacts with the sol-id 8 and the evolution of gas commences. Assuming, now that the pressure in the chamber 11 is less than the predetermined Zpressure indicated by the index 22, the pressure inchamber 11 will be insuificient to cause the diaphragm 19 to overcome the action of the spring 20, whereby this spring .will depress rod 18 and -unseat the valve 13. When valve 13 is amseated gas will flow from chamber 10, through duct 12, into chamber 11. The diameter cf duct [12 is so small that gas, but not water, may fiow therethrouh, and consequently the emission opening '0 this duct may be under water Without any detrimental effect on the action of the apparatus. The gas flowing into 11 increases the pressure therein forcing a greater quantity Ofi-WhitGI into contact with the solid 8 and thus enhancing the rate of gas evolution. chamber 11 has been raised -to the desired degree the diaphragm 19 overcomes the tension of spring '20, seating the valve :13 and closing the lower end of duct '12, whereby communication between the upper parts of chambers to and 11 is discontinued. As long as the pressure in chamber 11 does not fall below the predetermined pressure for this chamber, the valve 13 remains seated.
If the valve 16 of the service pipe 15 be opened, so that gas flows out of thechamber 10, an increased quantity of fluid will flow from chamber 11 against and through the bottom of the bell, whereby the pressure in 11 will decrease, the diaphragm 19 will drop a corresponding extent allowing the spring 20 to unflex and automatically unseat the valve 13. Gas will then again flow into the chamber 11, until the pressure therein is raised to the predetermined degree, thus again restoring normal conditions and causing the valve 13 to be seated. Should the pressure in chamber 10 .beitoo great, the:
lower. thus automatically diminishing the rate of gas generation.
When the :pressure in the apparatus operates is that of the difference in pressures in chambers 10 and 11. The generation of gas is dependent upon this difi'erence in pressures, the standard pressure being determined independently of the consumption and generation of gas, by the screw 21 and the parts coacting therewith, and it will be noted that irrespective of the quantity of gas consumed the predetermined standard pressure will always be automatically restored.
