When' thefbell'1is nearlyfull'of gasit is mostly `above the-surface of'the waterl' and thevehamberh 'isfthen just belowrthe surface.

Inathis"positiona'tlie pressure off-the water; y upon theairfwithin chamber isbutfay small* amountiso'itfscompressed but little. i There- E u' fore, it has its greatest volume and buoyant effort within the range of its operating movement. As gas is withdrawn' from the interior of bell 1 it gradually sinks. As it sinks a greater portion of Vits side wall isv immersed and it becomes lighter' Also, as the chamber 5 sinks the water pressure upon it becomes greater and the air within it is compressed into a smaller space. Thus, the chamber displaces less water than before and is accordingly buoyed up Vwith less force. Therefore, as the bell l sinks its side wall 1 becomes lighter and itsV compensating chamber becomes heavier, and by properly proportioning the volume of air in chamber 5 to the volume of metal in the side wall 1,V

the variation in theweight of the side wall 1 may be compensated by the opposite varia.

tion in the chamber 5.

In addition tothe air in chamber 5, there is always a certain volume of water'as designated by the numeral 9. Thisvolumeis controlled by the pressurer of the water upon the air within chamber 5. When the chamber is near the surface of the water the pressure of the water upon the air `within the chamber is butlittle. Consequently, the air is compressed Vbut a small amount and there is but a small volume of water inthe cham-v ber. When the chamber is'moredeeply submerged, the pressure of the water upon the air within thechamber is greater. Therefore, the air is compressed to a greater extent and there is a larger volume vof water within the chamber.l l

As the bell 1 is filled with gas the variable forcesl act in the opposite direction. For instance, as the side wall l emerges from the water it becomes heavier, and as the chamber 5 rises toward the surface of the water 4.- the air within it expands, due to the re'- duced pressure Vof the Ywater upon it, so it displaces more water and, consequently, becomes lighter.

In some cases thelbuoyant effect of the` chamber 5 may reduce the weight of the tank 1 so it [does not'exert suliicient pressure upon the gaswithin it. If so, a weight may be added tothe bell 1 as shown at 10.

If the position of the weight tends to make Guides of various kinds areffrequently.

Also gas supply and discharge may be through a plurality of conduits such as 2l and 2', and a vent pipe Y may be usedto conduct excess quantities of gas away from the tank in a manner well known in the art. These and other `changes may be madewithout altering the scope of this invention or its method of operation.

I claim:

l. In a storage gasometer, the combination of a tank adapted for holding a liquid; a bell to contain a'gas in communication only with said liquid through an openingprovided in the wall of said ,chamber below said gas i through which said liquid compresses said..

gas and varies its buoyanteffect on said bell according to its degree of immersion.V

2. In a storage gasometer, the combination of a tank adapted for holding Va liquid;

a bell adapted for partial immersion in said( liquid and also for containing a gas upon which said bell exerts a pressure; said gasometer being provided'V with suitable means including gas inlet and outlet conduits for varying the Vquantity of gas within said bell and thereby its degree of immersion; and an annular chamber connected to said bell and Y adapted to contain a gas in communication only with said liquid through anV opening provided in the wall of said chamberbelow the portion occupied by said gas aiid'through which: said liquid compresses said 1 gas and variesV its buoyant ettect'on said bell accord- .Y

ing to its'degree ofiinmersion.

.3. In a storage gasometer.Y having va tank,

a liquid in said tank and a bell partially immersed in said liquid; a compensator attached to said bell fand comprising a` submerged chamber adapted to contain a gas and having an opening therein below said gas and in communication only with said liquid byrwhich said gas is compressed so its buoyancy is reduced as the depth'of immersion of said compensator is increased. Y l

4. In a storage gasometer, the combination of a tank adapted forholding a liquid; a' bell adapted for partial immersion in said liquid and-also for containing a gas upon which said bell exerts a pressure; -a weight' on top of said bell; said gasometer being provided iio with suitable means including'separate gas`V inlet and outlet conduits for, varying thev quantity of gas within saidbell 'and thereby i through an opening in the wall of said chamits .degree ofv immersion; and a chamber lo cated within said 4bell and having a wall',

In a storage gasometer having a tank; .a liquid in saidtank; a bell partially iminersed in said liquid; and a compensator atn tached to said bell comprising an annular chamber submerged in said liquid, adapted to containa gas, and having an opening therein below said gas in communication only with said liquid by Which the degree of compression of said gas is Varied by the depth of immersion to vary the buoyancy of said compensator.
