WILLIAM TOWNSEND, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO GUARANTEE VISIBLE MEASURE SALES COMPANY, OF WASHINGTON, DISTRICT OF COLUMBIA, A CORPORATION.

LIQUID-GAGE.

such as gasolene, that has been poured into astorage tank or that is contained within a storage tank.

The object of the invention is primarily to provide a gage to take the place of the usual wooden measuring stick now commonly employed by dealers in gasolene to determine the amount delivered by the supply wagon to the underground tank. These wooden sticks are very unreliable, owing to the action of the gasolene which rapldly creeps up the stick and indicates a greater depth of liquid than has actually been delivered.

A further object of the invention is to provide the liquid gage with an elongated handle so that it may be lowered from theground line down into the buried tank; to provide means for guarding the indicating fingers or pointers against contact with the edges of the tank opening and so prevent their being bent or broken; to provide means for preventing unauthorized access to the pointers when they have once been adjusted; and to provide novel vent and inlet valves especially adapted for the gage.

These objects I accomplish by the construction shown inthe accompanying drawin in which:

igure 1 is a central vertical sectional view of the improved gage. Fig. 2 is a front elevation. Fig.3 is a rear elevation with the sealing Fig. 4 is a transverse section on line 414,

The glass tube A is contained within an inner tube B of metal or other suitable material which is provided with a longitudinal slot 72, through which the contents of the glass tube A may be viewed. The inner tube B is surrounded by an outer metallic tube C, having a longitudinal slot 0 in its front expansion spring f The valve stem 7 side registering with the slot 6 and having a longitudinal slot 0' in its opposite or rear side for apurpose to be presently described.

The tubes B, C are spaced apart from end to end of the slots 6, c, c and within this space slide the curved index fingers or pointers D. These indexes or pointers D are in the form of broken rings or bands encircling the inner tube'B, with their ends exposed through the slot 0, which-slot is somewhat wider than the slot 6. One end of every pointer has a character (Z indicating gallons, for instance, while the other end is formed as a pointer d. These characters 03 increase upwardly from the lowermost index or pointer, as 10, 20, 30, &c. Therear of every index D has a squared lug (Z extending into the slot 0 before referred to and provided with a threaded opening d into -which fits a binding screw d, the head of collar E, having at its upper end an internally threaded portion 6 screwed upon the exteriorly threaded lower end of the inner tube B, while below this threaded portion 6 the collar is exteriorly threaded at e for the internally threaded lower end of the outer tube 0, as clearly shown in Fig. 1.

The collar E is provided with an internal annular shoulder 6 on which rests a cushioning washer a engaging the lower end of the glass tube A.

Within this collar E is screwed the valve carrying plug E, between which and the lower sideof the shoulder e is placed a washer 6 The plug E has a central stepped bore in which the stem 7 of valve F works; the valve head f seating down wardly on the seat f formed in the upper face of the plug E. The valve is pressed down to the closed position by an encircling tends down below the lower end of the gage. so as to lift the-valve when the gage is lowered into the tank with the valve stem resting on the bottom thereof.

Specification of Letters Patent. Patehted S t 21 192 Inlet openings 7 are provided through and around the plug E and inlet openings 7' are also provided around the valve stem to permit the. fluid to enter the gage glass when the valve is raised from its seat 7.

The lower end of the valve setm f hasan enlarged removable operating toot f which works in the lower enlarged portion of the bore in the plug E.

The space between the upper and the lower ends of the glass tube A and the inner tube B is sealed with a cement G unaffected by gasolene, such, for instance, as litharge and glycerin.

Having described the lower inlet end of the gage, I will now describe its upper end, where H represents a collar somewhat similar to the collar E and having, like it, an internally threaded porton II, which screws upon the upper externally threaded end of the inner tube 13, and this collar H also has an internal annular shoulder it, between which and the upper end of the glass tube A is placed a cushioning washer 71*. This collar H i'its removably in the upper end of the outer tube C, to which it is secured y the screws l1". H is a valve car rying plug screwed into the collar H at the upper side of shoulder /i. The lower face of the plug H has a conical valve seat 11', from which a vent o )ening it leads directly through the plug 1 and collar H to the outer air. The vent valve it closes upwardly against its seat 72 by means of a spring 11 hearing against the upper face of the plug H and the lower face of an abutment /1' on the upper end of the valve stem.

A handle socket K enters the upper end of the collar H, where it is held to a limited sliding movement by a transverse pin or screw it", the outer headed end of which works in a short slot /1' in the collar H, while the inner end of the screw 71" extends under the abutment 7r so that when the handle socket moves upwardly the vent \alve will be positively lifted and held closed, but when the handle socket is pressed downwardly the screw or pin 1:" will move from under the abutment 11* and the upper end of the valve stem or the abutment will be engaged by the lower portion 1* and the valve h opened. 7

The upper end of the plug H has on its upper side a reduced extension it, which enters the lower end of the sleevelike extension Z of the handle socket K.

An elongated handle I is secured in the socket K, so that the gage may be lowered into tanks that are buried below the surface of the ground. The handle and socket may be removed from collar H by simply removing the screw 71. The rear side of the collar H is provided with a lug L, ha ving a transverse threaded opening 7, and the rear slde of the collar E is provided with a lug L provided with a vertically disposed recess Z; these lugs being in vertical ahnement with the rear slot 0 of tube 1\..

scaling cover or bar 31 of channel form is adapted at its lower end to enter the socket or recess Z and has a transverse screw 1 at its upper end to enter the opening 7 of the lug L. It will be seen, therefore, that after the pointers D have been properly adjusted for the particular tank with which the gage is to be used and the sealing bar or cover M applied all of the screws will be incloscd and protected from being tampered with.

The gage will be formed of suitable materials to withstand the action of the liquid with which it is to be used and will be made in sizes to suit the tanks. The pointers D are "thoroughly protected from contacting with any exterior objects so that when once adjusted they cannot be knocked out of position, even though the gage be carelessly handled.

By removing the screw it" the handle I may be laid alongside the gage for storage or shipment. The inlet and vent valves may be readily removed for cleaning and repair by simply unscrewing the plugs in which they are mounted.
