To all 'wii'o'm it may concernz' I Be it known that I, Ron BLACK, a citizen of. the United States, residing at- Gemfin the'county of Logan-and Statefof Nebraska, haveinvente'd certain newand useful Im-k 'provements in Processes and'Apparatus for Dispensing Liquids, of which the following is a- Specification. a 1

The invention relates to aliquid dispens ing device and has .as an, object, the provisionof a device which may be used for placing oil in thecranl: case of automobiles; 7

the outletpipel As 'sho wninth'e illustrated the invention is the provision-of a, device which shall utilize the force 'ofcompressed air to cause the liquid to rapidly escape from the outletof the container. P

. An illustrative embodiment of tion is shown; in the accompanying draw ings, in WhlCh-',-

Fig. l is a diagrammatic side elevation of an oil tank equipped with the'delivery-fde- 'vipe for attaching the can for reception of 01 .19. the container.iil-"isggivenf'a, partial rota;

the: container as'pring pressed valve islpr o 2 Fig. 2 is a with the view'of Fig. 1 showing the attaching means; ig. 3 is a central verticalsection of a fqrm of dispensing container; 7 I 3 Fig. 4 is a perspectivev'iew of a valve 'shownin'Fig. 2; .r Fig. '5 is a detail section on an'enlarged" scale of aportion. ofthe device shown in Fig.3; 3 1 I l*ig. 6 is a central vertical section of a cap. The device is especially adapted for use; with the usual form of oil tank 10 found in automobile service stations which are usually provided with a measuring pump built there i in. The container 11 shown in Fig. 3 is, adapted to be attached to the outlet '14: of; the pump, not shown, which pump maybe operatedby-means of ;-a crank 12 acting. through'a rack and pinion device 13. When; the container 11 is attached to the outlet 14 and the pressure of the pump is exerted I upon the oil to cause the same to be forcibly discharged into the container; air in the outlet pipe 1 4, as well as'the air already in the container 11 will becomp'ressed, bythe pressure of thepump toa' fraction otlits original volume, being trapped'over theoil' flowinginto container ll when; the container isapplied infan inverted, position f as is preferred. 1:

The invention is also useful in any other locationin which it is desired to supply a quantity ofliquid quickly and accurately under perfect control. Minor changes may be made-in the physical embodiment of the invention without departing from itsspirit.

, What I claim is: r 1. In a liquid dispensing device, in corn-v hination, a container comprising a nozzle having an internal valve seat, a plug in the bottom of said,container,' "a rod extending through said plug, a'valve carried hysaid rod coacting; with said seat the opening" .said plug being larger than said valve whereby the assembly of the. valve-and plug may he removed as a unit from the container. I v

:3. in a liquid dispens ng device, in cornh" atio'n; a container having a depressed bottom and a nozzle an internal valve seat carried by said rod coacting with said seat, a spring connected to said rod and operatagainst said plug to hold the valve upon is eat..'a handle upon said rod exterior of said plug wholly housed in saiddepression wherehy said container may sit upright upon the margin of its bottom. l 3.111 a liquid dispensing device, in ,COIlflhination a container having a nozzle, an"

for saidhno zzle a plug in said hott-or n a f valve rod pass ng through said plug, a valve internal: valve seat for said nozzle, a plug in the bottom-01 said container, a valve rod passing through said plug, a valve carried by said rod coasting withsaid seat, a han ,dle upon said rodr'e' zterior of said bottom,

cani upon said plug coactingwith said handle for retraction of'said-valve when the I handle rotatechspring ineans'to normally hold the vagl veupon its seat? 4. The process of charginga liquid dis-1Q pensing'dcvice which comprises introducing liquid thereinto by upward flow :with compression of trapped air in the container.

The-process of charging a liquid' dispensing device which comprises providing a container with an inwardly opening valve, attaching said contain'er to a supply of liquid under pressure in a position to trap air in said container. introducingliquid into said container under pressure with com-p es- 5 sion of trappe'd'air therein.

6. The process of charging a pensing device which comprises providing.

liquid disi 1 a container with airinwar'dly opening valve,

attaching said containerlin an lnvertedpo s1t1ontoa-source ofsupply or" liquid underpressure causing saidliquid to open' said valve andfiow. into said container with compression ofitrapped air therein.
