This invention relates to liquid dispensing apparatusf Y 'One objectoi' the-invention is to-provide "simple,reliable andeificient means for automatically draining the measuring container when the casing door of the apparatus is closed, as for example, when the'use' of the apparatus is discontinued for the night.

Another object is to provide a draining arrangement for liquiddispensing apparatus meetall requirements. r I I Theseand other objects are accomplished by means ofthe arrangementdisclosed on the accompanying sheet 'of' drawings in which Fig. 1 is a -vertical longitudinal sectional in "which the parts cooperatein a manner to View of liquid dispensing apparatus, embodying my invention; and

Fig. 2 isan enlarged detail sectional view of apart of the apparatus and disclosing the invention.

Fig. '3' is an enlarged "fragmentary sec- Y tional'elevation through the drain control valve. The various novel features of the invention will be apparent from the following I 7 device thus far described, it will be ap'pre description and drawings 1 and will be particularlypointed out in the appended claims.

Referring to the figures of the drawings it will be notedlthat the invention is illustrated in connection with liquid dispensing apparatus including transparent measur ing s container '10 mounted between aibaseplate.

.11 and a 'cover- 12. A casing 13' which supports the measuring container, :in turn is supported by a base 14. Mounted within the base 14 is a pump 15 for pumping liquids, such as gasoline, from anysuitable source represented by reference character 16 up through a supply pipe 17 which terminates in the U-shaped portion 18 within the container 10.

An overflow pipe '19 extending up into the container 10 determines the maximum height of the liquid within said container! A vertically adjustable discharge conduit 20 also extends into the measuringcontainer 10 and below the latter is provided withan oper-v ating handle 21 whereby the discharge conduit 20 may be, raised, lowered and rotated.

The discharge conduit may locked in vato hereinafter.

The drain pipe- 23 is connected at 3O to the'overflow pipe l9 so that liquid drained from the measuring container passes "through the'drain pipe23 and then through the overflow pipe 19 back to the source of "supply. Normally draining action is prevented'byf a valve 31 having-a stem 32. As",

shown in Fig. 1, the valve stenr 32 extendsout of the valve casing and the valve, under the pressure of the usual spring, is .releasably held "W v .ther description ofsame' willnot be givenf ia in closed position. As shown in Figure 2, the valve stem is pressed inwardly by a trigger 33 for opening the valve with the result that the measuring container is drained. Referring more specifically to the valve shown in Figure 3,1t willbe seen that the valve 31 is connected to the parts oi the drain pipe 23 and is provided with the valve stem 32 operated by one arm ot' the trigger 33, the trigger belng 'pivotallysupportedas at 51 to the'bracket 52 provided on the valve 31; The valve stem is provided with the valve disc 53 seated on the valve seat 5a and spring pressed by'spring 55 to maintain the valve disc in normally seated position, preventing draining through the pipe S'ecured to the outer end 56 ofv the trigger at the point 34- is a valve operating member 35, the upper end of which is provided with a lip 36 which as shown in Fig. 2 is engaged and raised by. a flange 37 on the low-er edge of the door 38 or the casing 13.

In other Words, when the door 38 is raised for completely enclosing the control mechanism of the pump, the lower flange 37 of the door 38 passes into engagement with the lip 36 of the operating member 35v and raises thelatter, for opening the drain valve, whereupon liquid is permittedto drain from the measuring container 10. \Vhen however, the door 38 is lowered, the valve automatically and immediately closesthrough action of the spring 55, the upper end ot the valve operating member 35 being enclosed or encased by a pocket portion 39 formed at the upper end of the door. This pocket prevents meddling with said member and also improper oper-v ation of said valve when the door is open.

thus housing the upper portion of the valve operating member .35, protective means is provided whereby the purchaser of liquid is more apt to secure the full amount of liquid purchased; i
