Application filed August 4, 1910, Serial No. 575,428. Renewed. May 4, 1912. Serial No. 695,323.

To all whom t may concern:

Be it known that I, CHARLES RosANZ, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Gas-Generator, of which the following is a full, clear, and exact description.

This invention relates to a new and improved apparatus for generating gas from a suitable chemical by the contact therewith of a suitable iiuid or liquid.

An object of this invention is to provide a device which will be simple in construction, inexpensive to manufacture, strong, durable, and reasily regulated, y

A further object of this invent-ion is to provide a device in which vthe amount of gas generated is automatically regulated by the pressure of the gas generated. I

These and further objects, together with the construction and combinat-ion of parts, will be more fully described hereinafter and particularly set forth in At-he claims. y

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar' characters of reference indicate corresponding parts in both views, and in which Figure 1 is a vertical section; and Fig. v2 is a horizontal section on the line 2 2 of Fig. l.

Referring more particularly to the separate parts of the device, l'indicates a suitable receptacle, in the form of a tank, which is preferably provided with a main bottom 2 and a false bottom 3 spaced apart from the main bottom 2 a suiiicient distance to form a chamber 4, which may be termed the gas storing chamber. Above the false bottom 3, the tank 1 is adapted to hold the fluid, such as water, which is to act on the chemical from which the gas is generated. For the purpose of supporting the chemical in the tank 1, there is provided a holder 5, which may be of any suitable character, such as a wire basket,`but is shown in this case in the form of a tubular rod or pipe which extends down through the false bottom 3 into the chamber 4, where it is provided with outlet openings.

On the pipe 5, there is provided a support, in the form of a disk stand 6, on which is adapted to rest the chemical to be utilized in forming the gas, which in this instance is shown in the form of cylinders 7 having central openings therein, whereby they are adapted to be slid over the pipe 5 and supported by the stand6.

For the purpose of inclosing the holder 5 and the chemical 7 carriedthereby, there is provided a cap 8, which' is in the form of a dome 9 having a vertical extension 10y connected thereto, of somewhat smaller diameter. The cap 8 is provided adjacent its lower end with a plurality of inlet openings 11, through which the fluid in the tank 1 can enter the lower and upper chambers provided by the dome9 and the extension 10. The fluid, such as water, which comes in contact with the chemical 7, such as calcium carbid, generates the gas Vin the chamber formed in the extension 10, and this gas can enter the pipe 5 throughan opening in the top thereof, from whence it passes down into the chamber 4. From the chamber 4 this gas can be drawn to the point whereit is desired to utilize it,'through a suitable connection 12, controlled by a valve 13. The chamber 4 is kept partially full of water to wash the gas as it comes therein. The amount of this water is gaged by leaving a. pet-cock 14 open until the water starts to come out, when the supply can be shut off. This water can be supplied to the chamber 4 either through the pipe 5, when the cap is removed, or through the pipe 12, or in any other suitable manner. l

For the purpose of covering and protect-v ing the liquid in the tank 1, there is provided a floating cover plate 15, which has a central opening 16, whereby it can be slidingly mounted on the extension 10, and is further provided with a plurality of perforations 19, permitting the transudation of any excess liquid.I This cover plate 1 5 may be locked in position by means of lugs 17 on the tank 1l The cover plate 15 is provided with openings 18, whereby it may be passed beyond the lugs 17 and secured beneath the same by giving it a partial turn.

The operation of the device will be readily understood when taken in connection with the above description. A suitable number of cakes or blocks of thechemical 7 are supported by the holder 5, and the cap 8 placed thereover, and a suitable liquid supplied to the tank 1. As soon as the liquid enters the openings formed in the cap 8, and comes in contact with the chemical 7, a gas will be generated, which will gradually force the level of the liquid within the cap 8, down,

and this gas will pass through the pipe 5 into the chamber 4. If the valve 13 is open, and the gas is being utilized through'the connection 12, it will continue to generate in the cap 8 as fast as needed. If, however, the valve 13 should be shut oli", -then the gas will gradually accumulate in the extension chamber 10, and thereby force down the level of the liquid within the cap 8 until the top surface thereof is out of contact with the lowermo-st block of the chemical 7 so that no more gas will be generated. As soo-n as the gas is utilized by opening the valve 13, the pressure within the extension chamber 10 will be decreased and thus permit the level of the liquid within the cap 8 to rise, permitting this liquid to come in contact with the chemical, thereby generating more gas. Inasmuch as the chemical is arranged in a vertical series of blocks, any diminution of the pressure within the cap v8 will permit the liquid level to rise within the cap 8, so that a greater amount of the chemical will be in Contact with the liquid, thereby generating a greater amount of gas. It will be seen that this. arrangement automatically regulates the amount of gas generated, according to the need thereof. As the lower blocks of the chemical are used up, the upper blocks will sink down to take their place, so that the generator can run a long time with a single filling.

While I have shown one embodiment of my invention, I do not wish to be limited to the specic details thereof, but desire to be protected invarious changes, modifications and alterations which may come within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a gas generator, the combination with a tank having a bottom, of a false bottom in said tank spaced apart from said first-mentioned bottom to form a storing chamber, a pipe extending in said chamber and having a communicating opening therein letting into said chamber and also extending above said false bottom to form a holder adapted to receive blocks of chemical having openings therein, and a cap in said tank adapted to cover said chemical and having an extensionl portion forming a chamber around the chemical on said holder, said pipe having an opening in the top thereof, whereby gas generated from said chemical may pass into said storing chamber.

2. The combination with a tank divided into upper and lower compartments by a false bottom, said upper compartment being adapted to contain a fluid, and said lower compartment being adapted to contain a washing fluid, forming a washing chamber for gas to be generated, a pipe extending from the bottom of said tank through said false bottom and above the top of said tank, said pipe having communicating openings therein between its interior and said gaswashing compartment, a collar on said pipe adapted to form the sole support for a column of carbid mounted on said pipe, a cap for said carbid and said' pipe, comprising a large dome and an extension of somewhat smaller'dimensions adapted to surround said carbid, said cap having openings therein, whereby the fluid in said tank may enter into said cap, a floating cover for said tank, means for locking said cover in said tank, and an outlet for said lower gas-washing compartment.

3.. In a gas generator the combination with a tank adaptedto contain water, a pipe extending from the bottom of said tank to a point above the top thereof and provided with a gas outlet near its bottom, the upper end of said pipe being open,means carried by said pipe to support carbid near its upper end, a cap comprising a lower, larger domelike part open at its lower end and extending a considerable distance below the carbid support on the pipe, and an upper, central contracted part extending upward from the carbid support and inclosing the upper end of the pipe whereby said contracted part projects above the tank and forms a handle part by which the cap may be readily lifted, the contracted portion of the cap forming a gas chamber of small capacity surrounding the carbid and the upper end of the pipe.

4. The combination with a tank divided into upper and lower compartments by a false bottom, the lower compartment forming a washing chamber for the gas, a gas outlet pipe extending from the bottom of said tank through the falsebottom and above the top of the tank, the upper end of said pipe being open and the lower end opening into the washing chamber, a carbid support on said pipe near its upper end, a cap comprising a lower large dome portion open at its lower end and extending a considerable distance below the carbid support, and an upper central contracted portion extending upwardly from the carbid support and completely inclosing the upper part of the outlet pipe, whereby said contracted part will form a gas chamber of small dimensions and will project above the tank and serve as a handle.

5. The combination with a tank, a removable cap extending near to the bottom of the tank, said cap being formed with a portion of large diameter wholly below the normal water level of the tank and open at its lower end and with a long comparatively narrow dome portion extending upwardly from the top of the larger portion, said dome portion beingclosed at its upper end and forming a gas space, the lower end of said dome portion being below the normal water level of the tank and having a diameter no greater than any other part of the dome, a holder for a cake of gas generating material, the support thereof being below the normal water level and adjacent the contracted portion of the cap whereby when the cake of gas generating material is in place it forms a substantial closure for the lower end of the said contracted portion of the Cap.

6. rIhe combination with a tank, a removable oap extending near to the bottom of the tank, said Cap being formed with a portion of large diameter wholly below the normal water level of the tank and open at its lower end and with a long comparatively narrow portion extending upwardly from the top of the larger portion, said narrow portion being Closed at its upper end and forming a gas space, the lower end of said narrow portion being below the normal water level of the tank, said narrowed portion having an approximately uniform diameter throughout, a gas cake holder whose support is adjacent the lower end of said narrowed portion and below the normal water level, whereby when superposed gas-cakes are placed upon said holder the lower one substantially closes the lower end of the narrowed portion of the Cap and the others substantially fill the chamber transversely thereof.

In testimony whereof I have Signed my name to this specification in the presence of two subscribing witnesses.
