Specification of Letters Patent.

?atented Feb. 20, io'oe.

Application filed may 23, 1905. Serial No. 261,872.

To all whoop it may concern:

Be it known that I, HENRY A. HOUSE, a citizen of the United States, and. a resident of Bridgeport, in the county of Fairfield and State ei fionnecticut, have invented certain no r and useful improvements in Liquid-lud icators, of which the following is a specification.

My invention relates to aptecl to showthe depth of liquid in stor-' age tanks; and it consists of an air-coinpressor located at the bottom of a storagetank and having one or both of its sides fiexible end adapted thereby to be acted upon by the weight or gravity oi the fluid in the tank to compress said side or sides of the compressor force the air therein up into anyinclicatlug-gage to show a reading or indication of depth of the fluid in the tank.

tion, rence is hall to the accompanying drawings, in Which- I Figure 1 represents a rear elevation of an indicating-gage, broken sectional view of the air-chambers located at the top and bottom of the indicatin glass, sectional view of a liquid-storage tanl; with the air-compressor inclosetl in a protective case located. at the bottom oi. the tank. Fig. is a detail upper plan view of the air-compression Fig. 3 is e. side elevation of the air? compressor end broken view oi the air-tube leading therefrom. Fig. i is a lan view of the protective covers inelosing t e air-compressor. Fig. 5 is a central sectional view of the, e'irwomprescor its covers or case. Tiigifi is shont elevation an indicating-gage and. view of a li L storage tank connected theiewith.

its construction and operation are es iollows: I i

1 represents an indieating-gagge hilly shown and described in my former application, filed May 2, 1905, Serialllo. 258,476. A brieiiu'le scription 01" this gage is all that will be neees sary to explain its connection with the ai compressor presently to be described.

'2 is the inclicatiugglass, located inthe rent oi the gage and shown in dotte l lines.

3 is a flexible bag-like li uid holding reservoir made of iubber or at er'like material,

with the into- 2, and 4 is e similar reservoir connected to the upoer end of the glass tube and adapted to hoki the air forced compressor is immersed in the fluid. liquid-indicators uiQ? others to understand my inven from the said tube when the liquid rises therein. 5 and 6 are caps inclosing said liquid and air reservoirs. 1

The air-compressor has, as shown, the two metal sides 7 and 8 to form the air-chamber 9, as shown at Fig. 5. These sides are made more or less flexible to suit the depth that the The demay, if desired, be regulated by corrugations, as shown, or in any other suitablev manner. As these flexible sides are liable to be damaged in'transportation, I inclose the compressor in the box-like structure comprising; the two covers 10 and 11, having the cri'itral openings 12 and 13 to admit the fluid, and cover these openings with the Wire-

netting

14 and 15 to prevent anything coming in contact with these sides that would be liable to injure them. 16 is a small. tube opening into the chamber 9 for the purpose presently to be described.

The compressor is ilaced at the bottom of the fluid-holding tan 17, having the -stufi'. ing-box 18, through which the tube 16 ex.- tends. The upper end of this tube is connected to the stand-pipe 19 of the indicating gage by means of the flexible tube 20. The pipe 19 opens into the chamber 21, in Which chamber the flexible recording liqui i-hol(l ing reservoir 3 is also situated.

The pressure exerted by the liquid in the tank on the. flexible sides of the compressor mill compress the same and foirce the air'from the corn ressor-chamber 9 up intothe chamgree oi" flexibility ber 21' ot the gage and compressthereservoir therein: up into the in either increase or decrease the pressure on, the compressor and give a corresponding 1nilieation of suchclepth on the ga I its before mentioned, the flexibilit of the "compressor is made I tank.- ln other Words, the compressor must .he sensitive enough 1/0 to suit the dept. of the ing on the gage when the tank is full, but

must instantly reset or expand as fast asthe to give an exact reading on liquid falls, so as highest to the lowest point the gage from. the of the liquid;

While ll show both sides ofthe com reseor flexible, 1 may, if desirable,- make 0 y'one side fie "ble but in either case it must be able not only show a r'eadto transfer to the indicating-gage not only the extreme depths of the liquid in the tank, but all the i aerrnediate depths of the liquid.

While I show a certain form of indicatinggage in connection with my improved compressor, I hold myself at liberty to use it with any other form.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, with a liquid-storage tank and an indicating-gage, of a flexible aircompressor having an air-chamber, said compressor located at the b ttom of the tank, a tube connecting said chamber with the gage so that, the pressure of the fluid on the compressor will force the air therefrom to the gage and give a reading thereon of the depth of liquid in the tank, for the purpose set forth.

2. Thecombination, with a liquid-storage tank, and an indicating-gage having an indicating glass tube, a flexible recording-liquidholding reservoir communicating with the interior of said glass tube at the bottom, and a flexible air-reservoir at the top of said glass,

said reservoirs inclosed by air-chambers, of a flexible air-compressor located at. the bottom of said tank, said compressor having an airchamber, a tube connecting said air-chamber with the air-chamber inclosirr'g the liquidholding reservoir of the indicator, for the purpose set forth,

3. The combination, with a'liquid-stofage tank, and an'indicating-gage, of a flexible air- Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 5th day of May, A. D. 1905.
