WILLIAM BANWARTH, OF GARY, SOUTH DAKOTA.

ACETYLENE-GAS GENERATOR,

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application iled January 3, 1912. Serial No. 669,203.

To all whom it may concern.'

Be itknown that I, VILLIAM BnNwAR'rH, a citizen of the United States, residing at Gary, in the county of Deuel and State of South Dakota, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

My improved generator is especially adapted for use in garages and other stations for the purpose of charging small tanks with acetylene gas to be carried on automobiles.

The object of my invention is to provide an acetylene gas generator from which charges of gas for small tanks may be drawn.

A further object of my invention is to provide means for varying the pressure of the gas in the small tanks; and with these and other objects in view, my invent-ion consists in the parts and combination of parts as will be hereinafter more. fully setfort-h.

The drawing is a vertical central section of an acetylene gas generator embodying my invention, parts being in elevation.

1 represents a cylindrical tank or generating chamber having a screw-threaded cap 2 and a screw-threaded base 3. The cap 2 is provided with a safety valve 4 of suitable construction and a central screw-threaded opening 5 into which a screw-threaded cap 6 is adapted to be secured. The base 3 is, as stated, screw-threaded to the tank 1 and is provided with supporting legs 7.

S is a drain or blow-ott valve in the base 3.

9 is a relatively long carbid container suitably perforated to admit water 10 from the tank 1. This carbid container is divided into a series of chambers by means of the partitions 11 to prevent moisture from passing by absorption from one section of the magazine or container to another. The chambers between the partitions 11 in the container 9 are adapted to be filled with carbid 1Q, as clearly shown in the drawing. The carbid container 9 is supported at the bottom in the tank 1 on standards 13, said standards being adapted to fit snugly againstthe sides of the boss 14 in the bot-tom of the tank so as to hold the bottom of the carbid container at a point above the bottom of the tank, as clearly shown in the drawing. The engagement of the supports 13 with the boss 1st centers the carbid holder in the tank. The top of the carbid holder is closed by reason of the fact that the screw plug G fits snugly thereon.

15 is a pipe or other suitable conduit connected with a water supply and with the bottom of the tank at 16, said pipe being provided with suitable valves 17 and 1S, there being interposed between the Valves a pump 19 which has direct communication with the pipe 15.

2O is a suitable handle connected to the tank 1 and to the piston rod 21 of the pump.

22 is a water gage having communication with the tank 1.

23 is a cooler and purifier partially filled with water and provided with a drier 24 which is positioned near its top.

25 is a drain valve for the purifier and cooler.

26 is a` pipe leading from the interior of the tank 1 into the cooler and purifier, thel lower end of the pipe being rebent as shown in the drawing.

27 is a pressure gage communicating with the tank 1 and 2S is a supply pipe leading from the cooler and purifier and provided with a valve 29 and a coupling 30, by means of which portable tanks may be connected for the purpose of being charged with the gas.

The operation of my invention is as follows: The carbid holder 9 is divided int-o a series of magazines by means ofthe removable partitions 11, but before inserting these partitions, carbid is placed in the container 9 until it has reached the level of the position ofthe first partition 11, whereupon the l partition is slid into the position shown in the drawing. Then the next magazine is filled and its uppermost partition placed in position and so on until the tank is entirely filled, as shown in the drawing. The valve 29 being closed, water is pumped by means of the pump 19 through the pipe 15, past the valves 17 and 18 into the tank 1, whereupon it flows through the perforations of the container 9 into the lowermost magazine and gas is generated from the carbid in such lowermostmagazine. The solid partitions 11 prevent the passage of water, by absorption, from the carbid in one magazine to the carbid in the next magazine. As soon as all of the gas is released from the carbid in the lowermost magazine, the pump is again started and the tank filled with water to the line shown in the drawing, whereupon gas is generated from the carbid in this magazine and as soon as all of the gas has been generated from the carbid in the second magazine, an additional supply of water is pumped into the tank 1 until it comes into contact with the carbid in the third magazine and so on until the carbid in all of the magazines of the container 9 has given off its gas. A suitable tank, for in stance one adapted to be carried by an automobile, is connected to the coupler 30 and the valve 29 is opened, whereupon the generated gas will flow through the purifier and cooler 23, through the drier 24, into the pipe 28, and thence into the portable tank. As soon as the portable tank is filled, the valve 29 is closed to prevent. further escape of gas from the tank l, when the portable tank is disconnected from the coupler 30 and placed in its position upon an automobile.

When all of the carbid in the container 9 has been used up, all of the gas can be forced out of the tank l by entirely filling the tank 1 with water, which enables me to lill small tanks connected to the coupler 30 by hydraulic pressure to any gas pressure desired.

l/Vhat I claim is 1. An acetylene gas generator, comprising a vertically disposed water tank having a valved drain port in the base thereof, and an internal centering boss surrounding said drain port, a vertically disposed perforated carbid holder, divided into a series of magazines and positioned in said tank coaXially with the drain port, a plurality of supporting standards carried by the bottom of said carbid holder and having their lower ends adapted to lit snugly against the outer sides of said centering boss, whereby the carbid holder is centered in the tank substantially as described.

2. An apparatus for producing and delivering measured charges of gas, comprising a vertically disposed tank, a carbid holder vertically disposed in said tank and adapted to carry carbid and having means for dividing the carbid horizontally into a series of stages to produce independent charges, and means for positively introducing into and trapping within the tank, measured charges of water, comprising a water pump communicating with the tank, and a check valve preventing back flow from the tank to said pump.

3. In a portable self contained acetylene gas generator the combination with a generating tank, a carbid holder in said tank, a water supply pipe leading into the bottom of the tank, check valves in said water pipe and spaced from each other, a pump cylinder connected to and having communication with the water pipe between said check Valves, a pump handle pivotally mounted on said tank, a piston in said cylinder and a piston rod connected to said piston at its lower end and pivotally connected at its upper end to the pump handle intermediate its ends.

4. In an acetylene gas generator, the combination with a vertically disposed tank having a central screw threaded opening in it-s top, of a perforated carbid holder constructed to pass through said opening into said tank, a screw threaded cap constructed to close said opening and seal the top end of said holder, imperforate partitions dividing the holder into a series of magazines, a port at the bottom of the tank, a pipe line connected to said port at one end and to a water supply at the other end, check valves in said pipe line, a pump cylinder connected to said pipe line and communicating therewith intermediate said valves, a piston and piston rod in said cylinder, and a pump handle pivoted at one end to the tank and pivoted intermediate its ends to said piston rod.

The foregoing specification signed at Gary, South Dakota, this fifteenth day of December, 1911.
