Application :filed May 15, 1922. Serial No. 561,244.

.- citizen of the United States, resident of Owatonna, county of Steele. State of Minnesota, have invented certain new and useful Improvements in Acetylene Generators, of which the following is a specilication.

The object of my invention is to provide improved means for sealing the main carbide hopper of an acetylene .generator against the entrance of air, said sealing means being adapted to open to allow the deposit of a night charge from the auxiliary hopper into the main hopper, and also to permit the insertion of a filling funnel to deliver a considerable body of carbide to the main hopper.

The invention consists generally in va rions constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a front View, partially in secr tion, of a carbide generator embodying my invention,

Figure 2 is a detail sectional View, showing the position assumed by the sealing means when the gas bell is down and the auxiliary hopper is in position to deliver a night charge,

Figure 3 is a similar view showing the sealing means open and a filling funnel in position for delivering carbide to the main hopper, t n

Figure 4 shows the sealing means in its closed position when the filling funnel is removed.

In the drawing, 2 represents an acetylene gas generator having a water chamber 3 and a bell 4: fitting between the jacket 5 of the generator and an inner shell or sleeve 6. This bell rises and falls in the space between the sleeve 6 and thejacket 5 of the generator as the supply of gas increases or decreases. 7 is the main carbide hopper, fitting within the sleeve 6 andI having a hopper bottom S with an opening 9 .through which the carbide is discharged into the water tank beneath. The hopper has aclosed top 10 and an opening 11 therein encircled by a sleeve 12 and the top of the gas bell has a sleeve 13 depending therefrom and adapted to telescope with the sleeve 12 and when the hell is in its down position, the

sleeve 13 rests on the top of the main hopper and forms an air-tight joint therewith. An auxiliary hopper 111 has a jacket 14h provided with a flange 1110 to rest upon the top of the gas bell, thelower end of said jacket fitting within the opening' in said bell and the sleeves 12 and 13. Thishopper is adapted to contain a supply of carbide for the night charge, and has a valve 14a, a cover 15, a yoke 16 .and a screw 17 mounted in the yoke and adapted to engage a lug 17'. This auxiliary hopper is removed b`odily from the bell for filling purposes and through the opening in the top of the bell when the auxiliary hopper is removed, carbide may oe delivered to the main hopper. A port 16 is provided in the top of the main hopper encircled by a gasket 19 and a valve 2O is mounted on an arm 21 pivoted at 22 on one side of the opening 18 and is seated against the underside of the gasket 19 for closing the passage therethrough, said valve being normally held in its closed position by a coiled spring 23. This valve seals the opening to the main hopper but is pushed open by contact with the lower end of the auxiliary hopper when the bell has nearly reached the liinit of its downward movement and may also be pushed open by the lower end of the lling funnel 2e that is thrust into the opening in the bell when it is desired to fill the main hopper with carbide. When the sealing valve is opened by engagement with the lower end of the auxiliary hopper, the valve 111@ may be opened to allow the night charge to fall into the hopper beneath. As the bell begins to rise through the formation of gas, the sealing valve will close automatically and prevent the entrance of air into the main hopper while the auxiliary hopper is being removed for filling purposes or for the insertion o-f the main filling funnel at which time there would ordinarily be a direct passage between the main hopper and the outside air. This passage will be closed by the sealing valve the instant the lower end of the auxiliary hopper or the filling funnel is withdrawn from the opening into the main hopper.

I claim as my invention:

1. An acetylene generator comprising a main hopper, a gas bell encircling said hopper, the top of said hopper having a filling opening and otherwise closed, said bell havi ng a filling opening an auxiliary hopper oi' filling funnel adapted to litnto saidl fillingopening and means mounted to close the filling opening in said main. hopperegainst the passage of air thereto and ymove; to an open position when engaged by said auxiliary hopper o1' filling funnel.

2. In combination, with an acetylene generator, Ya carbide hoppenheving. a closed top and a iillng opening therein, and a gas bell encircling said hoppen and,7 havinga fillingx opening oppositethe oxningA in Sad fhopper, eta Valve arranged tolnornielly close the iilllng Vopening into Seidhopp'er mid open under` pressureV thereon through Said gas bell opening to allo-W. lionT of the carbide i into saidAY hopper.`
