ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Application filed September 14, 1907. Serial No. 392,949.

.' b all whom it may concern:

Be it known that we, CHARLES E. WRY and CLAlR ,R. Jones, citizens of the United States, residing at Forest City, in the county of Winnebago and State of Iowa, have invented a new and useful Acetylene-Gas Generator, of which the following is a specisize as desired.

fication.

' The objects of our invention are, first, to provide a simple, inexpensive and eflioient self-feeding acetylene gas generator in which the carbid is stationary and the water elevated by air pressure to periodically wet the carbid': second, to provide means for safely refilling the carbid tank while the machine is in operation: third, to automatically elevate water into the carbid chamber as required for wetting the carbid and generating gas by means of air and pressure: fourth, to provide means forretain'ing the carbid chamber perpendicular relative to a water chamber as required to maintain water circula tion and preventing leakage: Our invention consists in the economic arrangement and combination of two Water tanks, a detachable carbid holder and a gas receiver as hereinafter set forth, pointed out in pur claims and illustrated in the accompanying drawing in which the letter A designates a main water tank that may vary in It has a closed top, 10, provided with a central open neck 12, to which is fitted a removable cap 13 to which ca is connected an air pump, 14, that is preferably fixed to side of the tank as shown. A flexible tube, 15, extends from the pump,14, to the cap 13. A second water tank B is connected. with the lower tank A by a tube 16 as required to allow continuous communication between the two tanks.

With the closed top of the tank B is com nec'ted a removable air-tight carbid holder C by a coupling 17 that is provided with a cutolf v'alve18. Above the coupling 17 is a cut off valve, 19. The valves 18 and 19 are only for the purpose of shutting off the water pressure when it is desired to refill the carbid chamber or in case of disconnecting the machine at-some other point. At all other times these valves remain open, leaving the water free to enter the carbid chamber whenever the gas pressure in the tank D is lower than the air pressure in the tankA; and also to allow water to drain out of the earbid chamber when-gas pressure in the tank D becomes stron enough to automatically force the water back into the tank B.

To support the holder C in a perpendicular position a skeleton frame, composed of circular bands 20 and 21 and'a plurality of uprights 22 fixed to the bands, is detachably band 23 fixed on the tank as shown, or in any suitable way, in such a manner that the upin concentric position therewith as shown in the drawing. The lower end of said holder is concave-convex and has a flat bottomed central extension 24 provided with a central screw-threaded opening into which the tube at the up )er end of the valve 19 is dot-a i. A screen 25 placed in the extension 24 serves as a drainer.

The top of the holder C has a neck 26 to which is detachably fixed a cap 27 and on the ca is a cut off valve 28. Another cut off valve 29 is detaehably connected with the valve 28 bya union 30. tor pipe 31 extendslfrom the valve 29 to a gas receiver D. By means of the union 30 it is obvious the pipe can be readily detached from the holder C as required re liminary for disconnecting the said he der from the water tank B. A gas distributing pipe 32 is'fixed to the receiver D and provided with a cut off valve 33. A pressure gage 34 on to of the gas receiver indicates the pressure 0 the gas confined therein.

In the practical operation of our invention when all the parts are pro or] y connected, water in the tanks A and and carbid in the holder G, air pumped into the tank A will force water up from the tank B through the open valves 18 and 19 as required to wet oarbid in the holder C for generating gas that -will pass up through the oarbid and through the 0 en valves 28 and 29 into and through the pipe 31 into the receiver D from whence it can 'he distributed to any number of burners that may be connected with said distributing ipe. The quantity of water in the tanks X and B and the quantity of air pum ed into the tank A regulates the u war pressure of the water in the tank and also the pressure of the gas in the holder C and the receiver D. And the air confined in the tank A will press water into and up throu h the' tank B as re uired to wet the carbitI in the holder C. e amount of air pumped on top of the water in the tank A or band 21 will engage the carbid holder C fitted to the topof the tank B to rest upon a I A gas eonducfunction and combination of all'its parts the forces the Water into the carbid chamber and retains it there until sufiicient gas is generated to force the water back out of the carbid chamber and compresses the air in the to of the tank A, as required to automatica ly drain the water from the carbid chamber and thus discontinue the eneration of gas. A stop cook 35 is provi ed at the bottom of the tank A for emptying the water from the tanks. A very simple and complete means of regulating the generation of gas and the quantity required is thus pro* vided by filling water into the tank A and pumping air on its top. w

aving thus set forth the purpose of our invention, the construction, arrangement,

be obvious.

What we claim as new and desire to secure by Letters-Patent, is

1. In an acetylene gas generator, two Water tanks beside each other and communieating at their lower ends, ,an air pump con- 1 practical operation and utility thereof will 1 2. An acetylene gas generator comprising 7 two Water tanks communicating with eachother at their lower ends, an air pump connected with one of said tanks and a carbid holder on top of the other tank, a tube connecting the carbid holder with the tank under it, cut off valves in said tube, a gas receiver, a pipe connecting said receiver with said holder, cut off valves in said pipeand means for distributing gas from the receiver,

.arranged and combined to operate as set forth,

CHARLES E. WRY. CLAIR R. JONES.
