LlQUD-IDSPENSlNG DEVICE.

i application tied March ia, 19a?. serial no. ivaeaa 'llhis invention relates to dispensing devices, and especially to an attachment or aufn iliary adjunct of an ordinary filling station tank from which gasolineis dispensed in gah lons and multiples of gallons. llt such filling stations, no provision is usually made for dispensing gasolinein fractions oit a gallon,

and the public is inconvenienced by this fact,V

especially because small quantities of gasoline are needed for various uses by housewives and others, and because it is dangerous, and sometimes unlawful, :tor gasoline to be kept in apartment houses and residences of cities and towns. Therefore, a inainobject of this in-Y` vention is to provide a perfectly safe, convenient and practical means of dispensing fractional parts of a gallon of gasoline from till- `ing stations primarily intended to dispense only gallons `and multiples of gallons.

Another object is to provide a device of this character which is applicable and attachable to various forms of .filling stands and tanks without alfectii'ig the utility thereof with respect to dispensing gallons and multiples of gallons.

Another object is toprovide a device of this character which is formed of comparatively `few and simple parts, so it can be manufactured at a comparatively low cost.

Uther objects and important features are pointed out or implied in the following details of description, in connection with the accompanying drawings in which:

Figure 1 is a view in side elevation showing a conventional forni of filling stand and tank having my invention applied thereto.

Fig. 2 is an enlarged central vertical sec- `tional view of the measuring device from which fractions of a gallon are dispensed.

F 3 is an enlarged detail view of one of the valve-controlling members such as shown on top of the n'ieasuring device in lili 2.

Referring to these drawings in detail in which similar reference characters correspond to similar parts in the several views, and in which the gallendispensingl tank@ and its supporting stand or base S, and dispensing hose H are shown to illustrate the application and an attachment oit the auxiliary dispensing device; the latter will now be described as follows:

il measuring receptacle is indicated at lt, as a whole, and is preferably formed as shown in Figure 2, having its bottom and top parts formed of cast iron or other metal, while its vertical wall is preferably a hollow glass cylindersuch as indicated at 5. The bottom casting includes a disk 6 wl'iich forms'the bottoni of the receptacle, and three tubular uprights or measuring tubes "l, 8 and 9 which extend to. different levels within the measuring reeeptacle. "lhe lower ends of these measuring tubes are in open communication with one another and with an internally threaded outlet or opening l() which is in threaded engagementwith a discharge pipe or drain pipe 11. 'lhe lower end of this pipe 11 is in opencom-` munication with the drain pipe D of the tank G, for a purpose which will presently appear.

The upper casting` includes a disk 12 provided with an inlet opening which is .indicated in dotted lines at 13, and an inlet pipe le connects with the dispensingfaucets 'F (of` the dispensing tank G) through the medium of a manually operable valve 15. rlhe disk 12 is provided with tubular bosses 16 which are. formed with cam-slots 1T, each of these canislots having a retaining notch 18 therein (see Figure 3), and these bosses 16 may be either formed integrally with the top 12, or secured thereto by any appropriate means. Valves 18 are provided to close the upper ends of the measuring tubes 7, 8 and 9, these valves being of any appropriate form, but preferably provided with guiding lingers orinembers 19 which insure the proper seating of the valves when closed, and permit gasoline to pass between thein and into the measuring tubes when the valves are open. For opening these valves, valve-rods 9.0 are provided, and the upper endof each rod is provided with a handle extending laterally and horizontally from the tops of the respective rods 'lfhese handles 9.1 are designed to slide in the respective cani-slots 17, and to rest in the respective notches or seats 18. lt will be seen that these seats 18 cooperate with the handles 21 androds 2O for holding the valves open, but the'cam-slots 17 ellcct the opening of the valves 'when the respective handles Q1 are turned therein toward the notches 18. For closing any one of the valves, its handle 21 is moved out oit the contiguous notch 18, and released, whereui'ion the valve gravitates to its closed position.

rlhe lower disk has an opening or outlet 9.2 with which a dispensing tube 23 is in open comn'iunication through a manually operable valve 2a, and this provides a dispensing conduit or outlet through which fractional parts of a gallon are dispensed into suitable receptacles l(notshoivn) provided the customers.

A bracket or shelf 25 is preferably secured on the dispensing stand S, and apertured lto permit the drain pipe 11 and dispensing tube 23 to extend therethrough, these cooperating vwith the inlet or supply pipe ll for securing the receptacle It in a. fixed or stationary posities f l The upper and loiver discs are provided with annular shoulders 26 against which are seated suitable gaskets 27 to form seats ,for the upper and lower ends of the hollowv glass 'cylinder 5 andv make the receptacle leak-proof or liquid-tightiandv the same time cushion the ends of lthe cylinder 5 so as to avoid breaking it When'the securing rods 28 are Y tightenedfby thenuts that are provided thereon and which coopera-te therewith to hold the parts 5, 6 and l2 together as an integral unit.

' The vope ration ivill Abe more clearly and easily understood by first khaving an explanation ofthe reasonfor varying heights of the measuring` tubes 7,8 and 9, and that is, tliatthe height offthe highest measuring tube corresponds to the ,level of one gallon of gasoline` or liquid in the receptacle Il, the next or middle tube 8 corresponds to the level of tyvoV It is filled .or partly filled to a level above the i top .of tube 8:. The valve l5 is then closed, and the middle valve lSis opened, so thel excess of 'gasoline flows through the pipes or tubesS and 11,@thence back intother drain tube 1D, and thence intoV the'usual supply tank which is not herein shown; then the valve Ql y is opened, and the. desired tvvo quarts o l' gasoline pass out through the dispensing conduit '2B into the receptacle'provided therefor. IIt

will be seen that the same operation should be pursued in case'a quart is desired, except in this case ithe valve 18 of the measuring tube iieaeso 7 is opened. Obviously, .the heights of the tubes 7, Sand 9 ,may be made for arbitrary fractions of a gallon or quantities of liquid expressed according to the selling price, for instance, five cents north, ten cents worth, twenty cents Worth, etc.

Although -I have described this form of my invention quite specifically, it is to be understood that 'I have no intention of limiting my patent protection to these exact and specitic details of construction and arrangement, but I may malge appropriate or desirable changes Within the vscopeof the inventive ideas as implied and claimed. l

lVliat I claim as my invention is:

ll. In a liquid dispensing device, the combination of a dispensing receptacle including an inlet and a dispensing out-let and an overflow outlet, a plurality rof measuriiur tubes communicating with the overflow outIet and extending to different levels in the receptacle and" having valve seats at their respective upper extren'iities, the top of said receptacle having openings vertically alined with the respective measuring tubes and a plurality of valve units eac-li including a handle and a stem and a valve closing element, these valve closing elements being normally seated on the upper extremities of the respective measuring tubes While the respective stems extend through the respective openings which arc alined with the respective measuring tubes, the respective handles being operable-to raise the 'respective valve elements from the respective measuring tubes and .thereby permit a surplus of the liquid to escape through one or another 'of the measuring tubes, means to engage With the respective handles and thereby hold the respective valves in raised position, and a valve operable to open and close said dispensing outlet and thereby dispense the liquid remaining in the rccelitacle after the surplus has escaped through one of the measuring tubes. I

Q. The structure defined by claim l, and cams on the top of said receptacle and cooperative with the respective handles for raising the respective valves from .the respective n'ieasuring tubes.

In testiniony whereof I aflix my si gnature.
