GASOLINE-DISPENSING rui vrr.

Application filed July 23, 1926. Sal-151' at. 124504.

Anobject of this invention is the provision of a gasoline dispensing apparatus of a construction whereby a determined quantity of gasoline or like fluid is pumped into a transparent tank or container, and wherein any predetermined quantity ofvsuch gasoline, or all of the gasoline may be withdrawn there from in an accurate and positive'manner so that the purchaser will obtain the exact I amount of the fluid ordered.

A further object is the provision of a gasoline dispensing apparatus or pump in which a transparent tank or container is employed,

" ing rod against whose handle portion swingable stop members, corresponding in number, and spaced equidistantly with respect to the indicators in thetank are singly movable so that the gasoline can be accurately dispensed in desired quantities and a back-flow of unused gasoline into the tank will be prevented.

A further object is the constructionof an apparatus for this purpose in which the parts constituting the same may be easily associated to produce a firm up-right structure; in which the gasoline may be dispensed in desired quantities in an easy and accurate manner, and in which the construction is comparatively simple and may be cheaply manufac tured. i

To the attainment of the above broadly stated objects the improvement further resides in certain other novel features of construction, combination and operative associa Figure 4 1s a sectional vlew on the line 44 of ,Figu're'3. a

Figure 8 is a sectional view on the line 8-8 of Figure7. a

Figure 9 is a detail perspectiveview of the upper ring member and the brace rods associated therewith;

It is essential that the hollow body or standard on which the transparent gasoline tank or container is supported, be erected in a firm and vertical upright position. Therefore, upon the concrete bed that covers the supply tank I bolt the substantially bell-shaped base 1 of the standard. This base, adjacent to its upper inwardly flanged top'2, is formed with an outer annular beadthat provides an upper shoulder 8 and on this shoulder there rests the outer hollow casing or standard 4 of the improvement.

Passing through the flanged mp2 of the base 1, at equidistantly spaced intervals, there are rods 5. Theends of these rods are beveled, and the lower ends of the said rods are engaged by nuts 66 which contact with both the upper and lower faces of the fia gea. The opposite ends of the rods pass through openings in a flanged ring 7 and these ends of the rods are engaged by nuts 88 which contact with both the faces of the ring 7.'

The casing or standard 4' has its upper end received in the annular depression provided by the flanged ring 7,. Resting onthe top of the "ring 7 and likewise contacting with the outer periphery thereof and surrounding theupper portion of the casing 4, there is the lower flanged end of anoutwardly bulged collar 9. The inwardly extending mouth of the collar 9 is formedw'ith an upstanding flange 10 and surrounding thisflange and resting on the top of the collar thereis the outer peripheral flange 11 on the metal base or support for the transparent tank or container. The periphery of thebase 12 is substantially U-shapedin cross section'and is therefore hollow Theinner annular flange thus provided is formed .with a shoulder' depression 13. The ring 7, between the open ings' that receive the rods 51tlierethrough, is

formed with other and smalleropenings'; and

through these openings there are passed threaded rods 14, there'being screwed on the said rods nuts that contact with the opposite faces of the ring 7, while the second ends of the rods 14 are screwed in the base 12.

Resting on the shoulder 13 of the metal base 12 there is the lower end of the transparent tank or container 16. The upper end of this container 16 is received in an annular groove formed on the lower face of a disc 17. Screwed through the top of-the U-shaped periphery of the base 12 there are rods which are likewise screwed through the disc 17 and these rods have screwed thereon nuts 18 which "5 contact with the outer face of the disc 17 to hold the same in tight engagement withthe tubular transparent tank or container 16. The disc 17 provides the top for the tank 16, the center of the said disc being covered by a plate19 that has a vent opening 20 therethrough.

Arranged to surround the disc 17, and held properly spaced therefrom by the rods 21 that have screwed thereon the nuts 18, there is the hollow flanged cap 22 of the improvement. The cap has inner ribs 23 that rest on the disc 17, and the rods 21 may have their outer ends headed or have screwed thereon nuts 24 that contact with the cap. The cap is centrally formed with a vent opening, and this cap may be also provided with a signal,

7 such as a globe 25, (Figure 1) that may encase an electric lamp bulb, the signal 25 being 32, the latter transparent.

The opposite sides of the transparent tank or container 16 may be protected by seg- ,mental grates 26, and in the tank, centrally between the confronting ends of these grates, and secured to the top and bottom of the said tank, there are vertical rods 27. Adjustably fixed on each of these rods there is an indicator finger 28. Each finger has a socket body 29 that is slidable on the rod 27, a bind ing element 30 holding the indicator fingers properly positioned with respect to each.

s In the showing of the drawings the tank is designed to contain ten gallons of fluid, and this fluid is pumped into the tank by a hand operated pum 3 31 connected to an inflow pipe being made up of any desired number of sections and the confronting ends of two of these sections are screwed in a boss in the metal base 12 of the tank 16. The up per. end of the pipe 32 is disposed a distance above the uppermost indicators 28 so that one gallon of fluid will fill the space between the top of the pipe and the said indicators. The top of the pipe 34 is surrounded by a shield 33. The overflow pipe has its top level with that. of the pump pipe 32. This pipe 34 is also constructed of any desired number of sections, the confronting ends of two of such sections being screwed in a second boss in the tank base 12.

Screwed through the bottom of the base 12 and received in the collar 9 there is a coupling 35. The upper end of this coupling is engaged by a screw member ornut that holds a packing 36 in the said coupling. The lower end of the coupling is widened and has screwed therein a tubular member that provides a gasoline discharge chamber 37. The coupling has an angle branch in which is screwed a pipe provided with a hand operated valve 38 disposed exteriorly of the collar 9, the valve casing having attached thereto the usual flexible dispensing hose 39.

The lower and open endof the discharge tube or chamber 37 is closed by a cap nut 40, and this cap nut has an angle passage in which is screwed a drain cock 41. Also the cap nut has screwed thereon a packing box 42 through which passes the operating rod 43.

The operating rod is connected by a pin to the lower end of the discharge tube 44, the latter having its upper end received in the tank 16 and the said tube, of course, passes through the packing 36.

One of the rods which I have designated by the numeral. 21 is hollow, and passing through this hollow rod there is an air vent pipe 45 which communicates with the widened or enlarged bore of the coupling 35 and with the top of the tank 16.

The operating rod 43 has fixed thereon a handle 46 that passes through a vertically disposed elongated opening in one side of the standard or casing 4. In this connection it should be stated that the operating handle for the pump 31 passes through an opening in the opposite side of the member 4. One of the rods 5 is disposed opposite the first mentioned opening, which latter for distinction is indicated by the numeral 47. On this rod there is fixed upper and lower brackets 48 and 49, respectively. The lower bracket 49 has a guide opening therethrough for the operating rod 43, the upper bracket 48 being shorter, and both of these brackets are connectedtogether by a brace rod 50 as well as by a second and inner rod 51. This last men' tioned rod 51 is provided with equidistantly spacedlugs, nuts or other enlargements 52. Resting on each of the enlargements 52, and swingable on the rod 51, there are the body portions 53 of stop members. These, stop members are equal in number, are spaced away from each other the same distance as the indicators 28 and have inscribed thereon numeralscorresponding to the numerals on the indicators. The body 53 of each stop member has its upper portion contacted by a helical spring 54, each of the said springs exerting a tension between one of the stops 52 and the body of the said stop members 53. The body of the stop members 53 have on one of. their edges outwardly'directed upper and lower fingers 55 and 56, respectively, the latter fingers serving as handles.

We will suppose that the tank is filled with gasoline and that the entire contents are to be Withdrawn therefrom. The operator exerts a downward pressure upon the rod 43 after he has swung the lowermost stop member 53 to bring its finger 56 in the path of contact with the hub of the operating handle 46. This brings the mouth of the dispensing tube againstthe packing nut on the base 12 of the tank, and consequently permits all of the gasoline from the tank to flow by gravity through the tube 44, the discharge chamber 37, through the valve 38, and the dispensing pipe or hose 39. Should only one gallon of gasoline be required the uppermost stop 53 bearing the character 1 is swung to bringits finger 56 against the rod 43, and when the hub of the handle on the said rod 43 engages this stop the discharge tube M will be drawn downwardly through the tank 16 a sufiicient distance to permit exactly one gallon of gasoline being dispensed as above described. In a like manner the swinging of any of the stops into contact with the handle of the operating rod 43 will cause the desired quantity of gasoline to be dispensed in a quick and accurate manner. Any air which may be created in the dispensing chamber will find an outlet through the vent pipe 45, and when the tank is not desired for use a suitable plate covers the opening 47 and the'handle for the pump 31 is removed. Any sediment in the discharge chamber will find an outlet through the cook 41.

I have herein set forth a simple and satisfactory embodiment of my invention as it now appears to me, but obviously the nature of the improvement is such as to necessarily render the same susceptible to changes and modifications. Therefore, it is to be understood that I do not hold myself restricted to the precise details of construction herein set forth and am entitled to make all such changes therefrom as fairly fall within the scope of what I claim, providing, of course, that such changes do not exceed the scope of the invention or sacrificeiany ofthe spirit thereof.

-Having described the invention, I claim 1. In combination with a gasoline dispensing tank having a pipe adapted to be projects ed upwardly thereinto .to various levels to determine the ELIIIOUIIt'OIE liquid to be drained from said tank, means for limiting the downward movement of said pipe comprising a rod attached thereto and having a handle thereon, a support adjacent said rod, collars on said support, stop members rotatably mounted on said support and resting on said collars, helical springs exerting tension between the under side of said collars and the top of the next succeeding stop member, and fingers on said stop member adapted to contact with said handle to limit the downward movement of said pipe.

2. In combination with the tank of agasoline dispensing apparatus, a tubeadapted to be projected vertically into said tank, a rod extending downwardly from said tube, a support parallel to said rod and having stop members 'rotatably mounted thereon, said stop members being limited in their down- Ward movement on said support by collars fixed to the support, helical springs exerting tension between the lower side of said collars and the top of the next succeeding sto said stop members having a finger adapte to be brought adjacent the path ottravel of said rod to indicate the correct positioning of the tube to permit the desired amount of liquid to be drawn from the tank.

In testimony whereof I atfix my signature.
