Specification of Letters Patent.

Patented une a, rare.

To allwii-om it may concern:

' for controlled by Be it known that l, GARLMARTINI, a subject of the German Emperor, and resident of Berlin, Germany, have invented certain new and useful improvements in Testing and Controlling Devices for Producersof' Inert Gases, of which the following is a specification.

My invention relates'to the production of inert gases suitable for the protection of inflammable liquids (say, gasolene) contained in tanks or receptacles from which air is excluded. I have produced such an inert gas by the combustion of a mixture of air and inflammable gas or vapor in a closed chamber to which no additional air is admitted. In the practical operation of the apparatus it is of advantage to provide means for testing whether or not the mixture fed to the producer has the proper constitution. lhis ll accomplish, according to one feature of the present invention, by introducing a portion of such mixture into an internal combustion engine, as the working medium therefor. Should the gaseous mixture become unsuitable, the engine will stop, thus calling attention to the fact that the apparatus is not working properly.

According to another feature of my invention, the heat of the producer of inert gases is utilized to control the operation and particularly the ignition of the tell-tale engine.

its objectto insure the sup 1y of a properly proportioned combusti le mixture of as orvapor and air to the producer, and or this purpose the pumps or other devices an engine the operation of which depends upon that of the producer of inert gases.

Reference is to be had to the accompanying drawings, in which- Figur 1 shows the producer conjunc' tion with the engine, and Fig. 2 illustrates the same parts'in connection with the devices for feeding air and fuel.

To the supply chamber-4; formed in the casing 2 I admit air and-' gas or vapor,

I either-mixed and through afsingle pipe 1 as "in Fig 1',,.or through separate pipes 1 and 1 asm Fig. 2.- A, partition 3 separates the A further feature of my invention has for feeding the elements of the mixture are.

chamber 4 from the combustion chamber 5 of the producer. The combustible mixture passes through the burner nozale 6 and after be ng thoroughly consumed (without the ad- IIllSSlOIl of any additional air), passes to the place of use through the pipe '2 which 15 preferably in alinement with the burner 6 so that the path of the combustion gases will be straight or nearl so.

The combustion cham er 5 (with its inlet and outlet) and the burner 6 constitute a producer of inert gas, which is closed entirely with the exception of such inlet and outlet, that is to say, no air can reach the producer in addition to the amount ted througlrthe pipe 1 or one of the pipes 1 and 1 and the producer chamber 5 is closed to the surrounding air.

lt is very important that the mixture admitted to the combustion chamber 5 should ha re the proper constitution, since otherwise it might not burn at all, or it might be consumed insufficiently, and in either event the gas leaving through the pipe 7 instead of I suitable for t e protection of inflammable liquids. In order to test the constitution of the mixture, I have provided a tell-tale device, which in the particular construction shown consists'of an internal combustion engine 9 which receives its motive agent through a pipe 8 branched oil from the chamber 4 and connected with the valve chamber 10 from which the working medium passes to the cylinder in the usual way. The engine therefore receives as its working medium, a portion of the same gaseous mixture whl is fed to the combustion chamberb. If the mixture within the chamber 4: is weakly explosive or not explosive at all, the engine 9 will stop and thus indicate that the pro ducer is not working properly.

The flame at the nozzle 6 may become extinguished accidentally, and in this case the mixture (containing a relatively large proportion of 0 gen) would ass unconsumed to the pipe In order t at the motor 9 may stop in this case also, the igniter tube 11 of the motor may berprojected into the combustion chamber 5 as shown, so that ignition will not take place if the flame be comes extinguished accidentally or because the mixture is not sutdciently combustible. These expedients for making the operation of the motor dependent upon the proper working of the producer of inert gases, may be employed separately or jointly.

As represented in Fig. 2, the tell-tale device or engine may be utilized to operate the devices, such as the pumps 12 and 13, which feed the gas or vapor and the air respectively through the pipes 1 and 1. For this purpose the fly-Wheel 14 of the engine may drive a countershaft 15 by means of a belt 16 and a pulley 17 and the driving pulleys 18 and 19 of the pumps 12 and 13 are connected by belts 20 and 21 with pulleys 22 and 23 respectively on said countershaft. Thus air and gas or vapor will always be supplied in the same proportion, and if the mix ture is not properly explosive, the motor 9 will stop, thus interrupting the feeding of the mixture and preventing the improper mixture from being forced through the pipe Of course, the igniter tube arrangement described with reference to Fig. 1 may be used in this case also, that is, the operation of the pumps 12 and 13 may be made dependent upon the proper ignition of the engme.

Certain features or combinations claimed in the present application are also shown, but not claimed, in my application No, 516974 filed concurrently herewith.

I claim as my invention:

1. The combination of a supply chamber, means for leading'air and fuel thereto, a combustion chamber, a burner connected with the supply chamber and located within the combustion chamber, an internal combustion engine connected with said supply chamber to receive fuel and air therefrom, and an ignition tube for said engine, extending into said combustion chamber.

2. The combination of a supply chamber having two outlets, a burner connected with one of said outlets, a combustion chamber in which said burner is located, an internal combustion engine connected with the other outlet, an ignition tube for the engine, ex tending into the combustion chamber, and means, driven by said engine, for conveying v fuel and air to said supply chamber.

3. The combination of a supply cha mber havin two outlets, a burner connected with one 0 said outlets, a combustion chamber in which said burner is located, said chamber being'inclosed and havingan outlet through having two outlets, a burner connected with one of said outlets, a combustion chamber in which said burner is located, said chamber being inclosed and having an outlet through Which the inert gas produced in said chamber may be conveyed to the place of use, an internal combustion engine connected with the other outlet to receive air and fuel therefrom, and separate feeding devices, driven by said ngine, for conveying fuel and air respectively to said supply chamber in constant proportions.

5. The combination of a supply chamber having two outlets, a burner connected with one of said outlets, a combustion chamber in which said burner is located, said chamber being inclosed and having an outlet through which the inert gas produced in said chamber may be conveyed to the place of use, an internal combustion engine connected with the other outlet to receive air and fuel therefrom, and two rotary pumps, driven by said engine, for conveying fuel and air respectively to said supply chamber.

6. The combination of an inclosed producer chamber having an inlet for the combustible mixture, aburner located within the chamber and connected with the said inlet, an outlet for conveying the combustion products to the place of use, and imperforate walls extending continuously from the inlet to the outlet so that the surrounding air may have no direct access to the interior of the chamber, thus insuring the production of an inert gas during the normal operation of the producer, movable means for feeding the combustible mixture to the said burner, an

internal combustion engine, a connection for leading to said engine, as its'working medium, a portion of the same mixture which is fed to the producer, and an operative connection between the engine and the said movable means, todrive the latter.

In testimony whereof I'hereunto aflix my signature in the presence of witnesses.
