This invention relates toliquid disp'ens-' ing systems andhas reference more particularl to improvements in apparatus for use in dispensing gasoline. r

In dispensing gasoline, it is customary to first pump the gasoline into an elevated glass container graduated in gallons. From this elevated container the gasoline-is run by gravity. into the fuel tanks of the automobiles. I

In Patent- No. 1,466,273, granted to me n August- 28, 1923, .I have described and claimed aliquid dispensingapparatus that is adapted for use where the gasoline-is transferred. from the underground storage tank into the glass dispensing container, by means of a pum as distinguished from installation .where the gasoline.

sure. In installations of this type it is often desirable to'locate the storage tank at some distance from' the dispensing apparatus which makes it desirable that only a single 'fied, I have shown an apparatus in which pipe shall he -needed to connect the tank with the" dispenser, In the patent, above identionly a single pipe is used'to connect the storage tank with the. condenser.

It is the objectof this invention to modify the'constructlonshown and described in my above referred to patent so as to simplify the same and so @s to make it possib e to place the overflow or float tank under round, instead of within the casing of the ispens- This makes it possible to.

draw the thspensin container into the float tank at nightand'm other ways simplifies the construction. I

. The above and other objects which'will appear as the description proceeds, are attained by means ofa construction and arran mentthat I-will now proceed to dein detail, reference for this purpose 'bein had to the accompanying 1n whic my invention is illustrated an which the single figure shows a vertical sec-' tion through a liquid dispensing apparatus constructed in accordancewith my present invention.

In the drawing numeral 1 designates a rent glasscohtainer that is graduated in gallons and fractions thereof. This bowl is clamped between ;the-'base mernber 2 and top 3 by means of a central for hard. The dispe bowl assembly rest's'upon the top of the conical casing 5. A.";j8 u0t1011 or .tank 17. is a float ope fill line 6 extends from the base bracket 7 7.to a point near. the top of the dispensing container where it termlnates a short distance below the upper .end of the fill pipe. A drain pipe 10 connects the strainer 11 with the delivery p; dispensing hose 12. A valve 13 serves to ntrol the escape of theliquid through the pipe 10. A by-pass indicated as a whole by-numeral 14 connects the drain pipe 10 with the overflow pipe 9. This byp'ass iscontrolled' by a stop-cock l5'which may be opened at n ht or whenever it becomes necessary or esirable to drain the container 1. Unless some s ecial construction, such as that describe in the above identified patent is resorted to, it becomes necessary to extend the overflow pipe 9 to the storage tank 16 which frequently in-- pared to the capacit 7 of the tank 16, but

which must be slight y larger than the container 1 so that it will be possible to drain the latter atany time. The suction orfill .line 6, in the preferred construction, extends through the tank 17, in the manner shown, and passes from thence tothe inside of the storage tank 16 near the bottom of which it terminates in'a-foot valve 18. Within the rated valve having a body portion 19 which is provided with an opening which is controlled by a movable valve member 20 that is connected to the float controlled lever 21 by means of a link 22. When the tank 17 is empt the valve is closed but "when liquid enters t e tank 17in suflicient quantity toraise the float 23, the valve member 20. is moved to open position,

wardly and into the dispensing container in a manner perfectly-obvious from an in spectionof the drawing. The. overflow pipe 9 enters the tank 17 in the manner shown.

It is now evident that any; overflow that may.

occur while filling the container 1, as well as the contents ofJthe latter when the stopcock 15 is opened, will flow into the tank 1 I have shown the tank 17 provided with a vent pipe 17 that extends upwardly and opens into the top of the measuringbowl.

.This permits the air to escape from the tank to the bowl when thelatter is drained. The storage tank 16 is filled through the pipe 24 and is vented through ipe 25. In order that the pump 8 may he primed, if th1s should become necessary, I have attached to the pipe 6, ate. point directly above the pump, a priming pipe 26 controlled by a valve 27.

Let us now assume that the parts are assembled in the manner shown and that the pump is operated. Gasoline will be transferred from the storage tank to the graduated container 1. When the level of the gasoline in the container 1 reaches the top of the overflow pipe 9, it will overflow through this pipe and pass into the tank 17. As soon as this occurs the pump should be stopped. No harm, however, will be done if the pumping is continued for as soon as the float 23 opens the valve, the pump, instead of raising gasoline from the storage tank, will merely return the gasoline from the overflow tank to the container 1. This circulation may be continued as'long as desired. At night or at any other time, when it is necessary or advisable to drain the container 1', the stopcock 15 may be opened. This permits the 'gasoline to pass down and into the tank 17 where it. will remain owing to the fact that the foot valve 18 prevents it from returning to the storage tank 16. The float 23 will, however, open valve 19 and when the pump is operated the liquid in tank 17 will be the first to be returned to the container.

As soon as the valve 19 closes, liquid will beraised from the storage tank. I have shown the fill line 6 as passing throughthe tank 17, but this is not absolutely essential, although desirable for structural reasons. It is evident, however, that the pipe 6 may merely have a branch extending into the tank 17 and controlled by a valvelike the one described.

The main point of distinction between m prior invention, above referred to, and tlns one is that in this construction the overflow pipe opensdirectlyinto the tank 17 andthe latter is large enough to permit the entire contents of the container 1 to be drained into it; This makes it possible to use a foot valve in the lower end of the fill pipe which cannot be done where the .float tank is smaller than the container 1. With my present construction the tank 17 maybe placed underground which minimizes the fire risk. In the patent above referred to, there is no foot valvecorresponding to the valve 18 as this would prevent the overflow from returning to the, storage'tank. The tank 17 is shown broken away and has any capacity at least slightly greater in volume than the transparent container 1.

Having now described my invention, what I claim as new is: 1

An apparatus for dispensing liquid in measured quantities, comprising, in combination, a storage tank adapted to be placed under ground, a measuring bowl adapted to be supported. in elevated position above the storage tank, a suction pipe connecting the storage tank and the measuring bowl, a

pumpin said suction pipe, for transferring liquid from the storage tank to the measuring bowl, an overflow pipe extending downwardly from a point within the measuring bowl, an overflow tank between the measuropening and a check valve in the suction pipe between the overflow tank and the storage tank, said overflow tank having a capacity at least as great as the maximum capacity of the measuring bowl, whereby the entire contents of the'latter may be transferred to the overflow tank and a vent pipe connected at its lower end with the overflow 1 tank and having its upper end opening at a point above the maximum liquid level of the measuring bowl.

In testimony whereof I afl'ix my signature. EMORY OROUSE.
