LIQUID-DISPENSING APPARATUS.

Applieation filcd July 25, 1925. Serial No. 46,121.

My invention relatesto improvements in liquid dispensing apparatus of the so-called visible type, commonly used for dispensing gasoline. The apparatus has a Vertically adjustable tube and belongs to that class of such aparatus in which the adjustable tube is on the delivery side of the pump in contra-distinction to those having an adjustable overflow tube.

In apparatus of this type the elevated visible measuring container is provided with a fixed overflow pipe to drain back liquid to the maximum measuring capacity of the container and the movable discharge pipe whereby any portion of the remaining liquid may be accurately drawn off for delivery by adjusting the height of the discharge pipe below the open end of the overflow pipe and thus permitting the discharge of the measured quantity of liquid.

The principal object of my invention is to provide in such an apparatus means for quickly and accurately dispensing the entire number of units of liquid which the apparatus is adapted to contain or any less quantity.

Another object of my invention is to provide a dispensing apparatus in which the visible container is set low to facilitate the reading of the quantity graduations onthe container, at the same time having the liquid delivery outlet from the container high enough to permit the rapid and complete draining of the hose into thecontainer ot the customers vehicle. The means employed for accomplishing this is a U-tube and means for preventing liquid being siphoned -from this tube on completion of the measure for such siphoning would give false measure.

In the particular embodiment of my invention selected for illustration Figure 1 is a dispensing apparatus of the visible type shown in vertical axial section certain of the pipes being shown in full line where it is thought that such showing better illustrates the structure, and

Fig. 2 an enlarged cross section on line 2-9031. Fig. 1 as though shown there in :tull.

Referring now to the drawings, A is the post portion of the casing resting upon the pedestal A and having at its top a cap A the three held together by tie rode a in the usual manner. Upon the pedestal is secured a bracket a in which a quantity stop rod is pivoted and to which a guide rod is secured, as will hereinafter be more fully described.

A glass "container B is secured between the cap A and top plate Z) by tie rods 6 in the usual manner. A hand hole cover 6 facilitates access to the visible container. The container is provided with the usual quantity graduations as indicated in Fig. 1, the container shown being of five gallon capacity.

A fill .pipe 0 is connected in the usua manner to any suitable pump (not shown) which draws the supply of gasoline or other liquid from an underground storage tank (not shown). At its topthe fill pipeC is provided with a deflector cap 0 which permits quiet filling of the container B to a height above the level of the top of the overflow pipe D, which is lixed in position to rain back excess liquid to the zero graduation on the container B. The overflow pipe D connects with the storage tank in the usual manner. j

A vent hole 0 is provided in the top of the deflector cap to prevent liquid being siphoned out Of the visible container B below the zero point upon cessation of pumpmg. i

Into the cap A is threaded. from below one leg E of the U-tube and the discharge tube Fis adapted to be vertically adjusted withinthe tube E through the stuifling box a to prevent the escape of liquid from the container B around the tube F into the tube E.

At its lower end the tube E is provided with a return bend casting E forming the base of the U and the other leg E of the U-tube is secured to the member E At the top of the tube E is secured an L e and a horizontal discharge tube a with any suitable serve valve 6 to control the flow of liquid to the customers car.

At a point beyond the serve valve 6 is connected a vent pipe 6'' which preferably extends int-o the free space at the top of the container B, and ensures complete and rapid draining of the hose H.

In line with the center of the pipe E through the bottom of the U E is an opening with a stuliing box a through which extends the ustinent rod 7 which is secured.

i to the lower end of f of the tube F in any suitable manner, as by fork and rivets as lower end to a crosshead 7 which is raised and lowered .by means ofthe rack f pinion f andcrank f A crosshead guide rod f is secured at the bottom to bracket (11, and at the top to a cross plate a and extends through a hole in the crosshead- The height to which the discharge pipe F is adjustedwfrom time to time is controlled by any suitable stop mechanism, as that shown by stop rod G pivoted at the bottom in bracket a and at the top in cross plate (L3. It is provided with a pluralityot individually adjustable stops 9 fixed to the rod G, and the rod is rotated into suitable eon- H tacting'position of anypredetermined stop g-by meansrof'the bevel g on the shaft 9 I' do not intendt'o' limit myself to the precise structure shown but claim as within the gears 9 g and knob scope of my invention'any apparatus readable on the claims.

Iclaim as my invention and desire to secure by Letters Patent of the United States: i j i 1. A liquid dispensing apparatus having in'combination an elevated measuring contamer for the liquid to be dispensed, a

leg except through said discharge pipe, the other leg of said U-tube terminating in an outlet pipe, and means connected with said outlet pipe for breaking the siphon from said U-tube.

2. A liquid dispensing apparatus having in combination an elevated measuring container for the liquid to be dispensed, a U-tube whose vertical legs are constantly in fluid communication with each other below said container with one leg connected therewith a discharge pipe v'erticall adjustable within said container and Sillt leg of the U-tube, a stuffing box in the bottom of the container through which said discharge pipe passes, the other leg of said U-tube tenninating in it serve valve and hose connection, and a vent to facilitate the complete and rapid draining of the hose and thus prevent siphoning liquid from the U-tube.

3. A liquid dispensing apparatus having in combination a transparent elevated measuring container for the liquid to be dispensed, a U-tube whose vertical legs are constantly in fluid communication with each other below said container with one leg connected with the bottom thereof, a discharge pipe open at both ends to form a liquid passage fromsaid container to said leg of the U-tuhe, an adjusting rod secured to said discharge pipe extending down through a stuffing box in the return bend portion of said U-tube, means for adjusting the vertical height of said discharge pipe by means of said adjusting rod, a stufiing box in the bottom of said container through which said discharge pipe passes, the other leg of said U-tube terminating in a serve valve and hose connection, and a vent to facilitate the complete and rapid draining of the hose and thus prevent siphoning liquid from the U-tube.

In testimony whereof I have hereunto set my hand.

LINNAEUS E. BAKER.
