GABRIEL A. BOBRICII, OF LOS ANGELES, CALIFORNIA.

RECEPTACLE FOR CONTAINING LIQUID IR OR OTHER GASES.

v\ SPECIFICATION forming part of Letters Patent No. 673,073, dated April 30, 1901.

Application filed November 8, 1900. Serial No. 35,879. l 'ttlo model.)

To all whom, it may concern/.j

Be it known that I, GABRIEL A. BoBRIox, a citizen of the United States, residing at Los Angeles, in the countyof Los Angeles and State of California, have invented certain new and useful Improvements in Receptacles for Containing Liquid Air or other Gases, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

This invention is an improvement in vessels or receptacles for containing liquid air or other gases which cannot safely be confined in hermetically closed or sealed receivers; and the object is to provide a more effective insulation for such vessels whereby the evaporation of the liquid contents due to the absorption of heat from the atmosphere will be reduced to as low a point as possible.

The principle which is common to the several forms in which my improvement is or may be carried out is that of selfinsulationthat is to say, the cold air or gas resulting from the evaporation of a body of the liquid is caused to circulate through a connected series of concentric chambers surrounding the in the novel and effective manner hereinafter described.

Heretofore it has been proposed to surround the containing vessel by two or more concentric chambers or compartments and to'cause the expanded air or gas to pass through the said compartments in direct series; but this plan, while effective to a certain extent, has this objection: that the temperature of the air or gas in eachcompartment is higher than in that immediately adjacent to and inside of it, so that although one compartment serves in a measure as an insulator between its adjacent outer and inner compartments there is nevertheless aninterchange of heat between it and the inner compartment. To avoid this, instead of conducting the expanding air or gas directly over itself I direct it through every other compartmentthat is to say, I leave between two compartments through which the current of air or gas is iiowing in series an inert compartment filled with any suitable adiathermanous material. ,To whatever extent this plan be carried out it will be found to be attended by beneficial results, for since any given inner compartment can ab- Sorb heat only through its surrounding compartment, which latter is itself insulated by air or gas at a temperature but little higher than that of said inner compartment, the interchange of temperatures between the inner and outer compartments will be very slow.

In the accompanying drawings I have illustrated the manner in which the invention may be carried out, .the figures representing in central yertical section three forms or modifications of the improvement.

. In each of said figures, A represents a containing vessel, which constitutes the inner- -most of a series of concentric receptacles, (designated by the letters B and O.) The vessel A may be designed simply to hold a quantity of liquid air or gas temporarily to enable it to be transported from place to place or stored until used, or it may be capable of withstanding a high pressure and designed to serve as the receiver for a refrigerating plant or the boiler for an engine. It is not generally essential in such case that the inner compartments be capable of withstanding high pressures, as will be understood, for the main A purpose of such inner com partments is merely tocontain the liquid or to insulate the containing vessel, so as to reduce the evapora- `tion of its contents due to the absorption of heat from the atmosphere to a minimum. The inner compartment is filled through a tube c, the liquid is withd rawn or forced out through a tube D, and the pressure within it is shown by a gage E, connected with a pipe F. The tubes or pipes c and D pass through the walls of the several compartments. The tube F may be connected with the inner or an outer compartment. Theconcentriccompartments are filled with a porous adiathermanous material, such as lnineral wool. From the upper portion of the inner compartment a tube G extends downward through the space reserved for the liquid and through the walls of the said inner and its immediately adjacent compartment opening into the second insulating-compartment'O. The remaining compartments are connected in series with this said compartment in such manner that air or gas flowing through the pipe G must IOO traverse each successive compartment in alternately opposite directions, escaping finally through an outlet H. There Will thus be left one compartment B adjacent to that containing the liquid through which there is no circulation of air or gas, and any heat which reaches the liquid must therefore traverse this compartment after having been taken up from the second compartment B, filled with air or gas but little higher in temperature than the liquid itself.

I have applied to the compartment B the term inert, by which I mean to imply that it is an insulator in itself or composed of in part or whole an adiathermanous substance. This principle may be carried out more fully, as shown in Fig. 2, in which every other compartment throughout the series is connected, so that there will be a series of inert compartments alternating With those through which air or gas is owing.

In Fig. 3 a modied arrangement of this plan is shown, in which the top of the innermost compartment, Which aiords a channel for the expanding air or gas, is connected with the bottom ot the next but one compartment by a pipe K, which passes through the intermediate inert compartment.

Many other modifications of the invention will readily suggest themselves.

What I claim as my invention is- 1. A containing vessel for liquid air or other gases in combination with a series of concentric chambers or compartments completely surrounding the same, some of which compartments are connected in series With the containing vessel to form a passage for the escape of expanding air or gas, the other and intermediate compartments being inert, as and for the purposes set forth.

2. A containing vessel for liquid air or other gases comprising in combination an inner compartment for the liquid, an inert compartment completely surrounding and inclosing the same, and an outer compartment completely surrounding and inclosing the inert compartment and connected with the inner compartment to form a passage for the circulation of the air or gas which evaporates off from the liquid in said inner compartment, as set forth.

3. A containing vessel for liquid air or other gases, comprising in combination an inner compartment and a series of concentric outer compartments each completely surrounding and inclosing the inner compartment, the alternate outer compartments being connected in series with the inner compartment and with the outer air respectively, to form a passage for the escape of expanding air or gas. o

4. A containing vessel for liquid air or other gases comprising in combination an inner compartment and a series ot' concentric outer compartments completely surrounding and inclosing the same, and containing an adiathermanous material, the alternate outer compartments being connected in series with the inner compartment and the outer air respectively to form a passage for the expanding air or gas, as set forth.
