LQUIDv-DISPENSING APPARATUS.

Application ledllay 26,

My invention relates to liquid dispensing apparatus and particularly to means for com'- pletely draining the liquid in the elevated reservoir back to the storage tank. In such apparat-us the elevated reservoir is made of glass, hence this particular type is generally called visible dispensing apparatus, and they are used principally for dispensing gasoline. j To decrease fire hazard some means for completely draining the contents of the elevated reservoir back to the storage tank is usually required, and one means vis through tliedischarge hose and nozzle into the overflow pipe and thence to the storage tank.

The main idea. is set 'forth in the patent to Edward N. Kern, No. 1,210,812, issued Jvanuary 2nd, 1917. The principal object of this invention is to provide means for securing the hose nozzle to the projection Jfrom the ove1loWpipe,when the former is inserted in the latter for draining the elevated reservoir, so that the nozzle cannot become accidentally displaced or be removed by unauthorized persons.

Another object is to make such a joint between the hose nozzle and its socket in the overflow pipe as to prevent Water drainage into "the storage tank therethrough, gas escaping therefrom or the insertion of foreign material of any kind by malicious or mischievous persons.

Another object is to provide means for keeping the opening to the overflow pipe closed when the hose nozzle is removed therefrom.

In the particular embodiment of my in-v vention selected for illustration Figure 1 is an elevation of a visible dis-` pensing apparatus of the so called wet hose type, shown from the'discharge and drain back side, with the hose nozzle in drain-back position,

Fig. 2, is an enlarged section thru a portion of the lower part of the edestal, exposing the lower part of the rain-back tube and the lateral pro'ection therefrom, the top ofthe projection s own with the cap locked thereon as it would be when the apparatus y is in use, these parts being shown in axial section, and

3, an enlarged detail, shows the lower' part of the hose with valved nozzle attached. Referrin now to the drawings, A is vthe pedestal o a visible dispensing apparatus, with base a and cap a1 which forms the bottom fitting 02.

which is surmounted by the top head a2, the V reservoir C being held securely in placeby tie rods a3. i

The reservoir C is filled with gasoline from an underground storage tank, not, shown, by means of a pump P,'through a supply-pipe, designated as p below the pump and pl above it.

An overflow pipe O terminates within the reservoir at such a height as when .the reservoir is filled ready to serve customers, the guantity equals the maximum amount to be ispensed at one time, generally five or ten gallons; and it is adapted to convey excess liquid back to the storage tank.

From a T, 0 in the overflow pipe extends to the side thru the pedestal A an angular projection o1, terminating at the top in a tting o2, with an annular boss 03 upon which seats a packing washer' 04, when the cap o5 is closed and secured by the lock 06 as it is when the apparatus is in service.

Pins 07. extending thru the sides of the fitting 02, protrude .inwardly a short distance so that they will-enter the bayonet slots al on the sides of the nozzle D, when the cap o is raised and the nozzle is inserted in the When the nozzle is so-inserted, it is pressed down and rotated to the. left, the pins o7 entering the oblique portion d1 of the bayonet `slots d causing the packing washery d2 to seal the joint between the boss o3 and the nozzle flange de, making a joint that will be gas tight. When in this position the nozzle Vis locked against displacement by thepadlock d3 -which secures the guard d* to a. bracket a4, onthe pedestal.

It will be noted that the nozzle D has a valve d shown closed in Fig. 3, and open in Fig. 1, because the valve lever l5 is depressed by the bracket a". The cap o5 is so formed as to be self closing when the nozzle is removed. When in service the fitting o2 is always closed whether locked or not, and when locked up for the night the hose valveis alwa s open to ensure complete draining of the g ass reservoir C thru the hose H.

I do not wish to be limited to the precise (mechanism herein shown and described, but

:conceive as within the scope of my invenitif'n, all forms readable on the claims.

charge nozzle on the other end of said hose, dfliose adapted to completely drain said i Ui oitaiier, a drain-back pipe adapted to drain back to storage liquid in the container in excess of the maximum quantity to be served at one discharge, a pipe connected to Said drain-back pipe below said container and `adapted to receive said discharge nozzle7 said pipe open at its outer end, a'self closing cap normally keeping said open end closed, pins extending internally from the inner wall of said pipe connection and near its open end, a valve in said discharge nozzle, a flange and a. packing washer on said nozzle, bayonet slots onsaid nozzle adapted to coact with said pins in said pipe connection, and means for maintaining said nozzle valve in open position when said nozzle is inserted in said pipe connection.

2. A liquid dispensing apparatus, comprising an elevated reservoir from which liquid, is dispensed, a hose attached to said elevated reservoir to drain it, a nozzle for said hose, a drain-back pipe adapted to return to storage liquid in said reservoir in excess of the maximum quantity to he served at one dispensing discharge, an open conduit connection below said reservoir extending laterally from said drain-back pipe and having an open end adapted to receive the discharge end of said nozzle and a weighted cap keeping the open end of such connection closed except when lield open. y

In testimony whereof I have hereunto set my hand.
