PUMPING DEVICE.

Epeciflcation of Letters Patent.

Patented Nov, 5, 19120 Application filed April 12, 1912. Serial No. 690,344.

To all whom it may concern? .Be it known that 1, CHARLES L. Hanannnns, a citizen of the United States, residing at Madison, in the county of Morgan an N State of Georgia, have invented certain new and useful Improvements in Pumping Devices, of which the following'is a specification, reference being had to the accompanying drawings. 7

. This invention comprehends certain new and useful improvements in self measuring pumps and attachments therefor, and the invention has for its primary object a simple and efiicient construction of device of this character which may be conveniently used in dispensing gasolene or other liquids from the steel drummer barrels in which such liquids are shipped. I

A further object of the invention is an improvedpump attachment by the use0f which the pump may be quickly and securelyattached to the top of a drum or other storage receptacle or reservoir, and the liquid directly dispensed therefrom and measured as it is discharged from the pump.

A still further object of the invention is a device of this type embodying an improved construction of automatically adjustable foot valve support, whereby the inlet tube of the pump will automatically adjust itself for drums of varyin heights.

The invention also has for its object, in a device of this character, improved means for excluding dust and air from the inlet opening of the drum when the pump barrel or stock is mounted therein. And the inven tion also aims to generally-improve devices of this class and to render them more useful and commercially desirable.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure l is an elevation of my improved measuring pump and attachments therefor; Fig. 2 is a similar view, partly in section,

taken at right angles to Fig. i; Fig. 3 is a top plan view,- parts bein broken awa Fig. i is a sectional view 1; rough the in ct pipe of the pump; and Figs. 5, 6 and 7 illustrate modifications hereinafter specifically referred to. I

Corresponding and like parts are referred to in the following description and indicated in the accompanying drawings by like reference characters. a

In connection with my improved measur-= ing pump and its supporting attachments, I preferably employ a truck 1 Whichis mounted on traveling wheels 2, whereby the drum or other fluid may 1 is formed with three points of bearing, each of which is recessed to fit over the rim flange and carries an inwardly disposed adjustmg screw 6 and an outwardly disposed ten- I sioning screw 7 whereby the base bar 5 may be securely connected to the top of the drum. The base bar 5 is provided with upwardly projecting stud bolts 8 near one end, said stud bolts being laterally spaced from each other, as clearly illustrated in the drawings, and being designed for insertion through openings formed in the base flange 9 of-a pump barrel 10, nuts being screwed on the upper ends of the bolts 8 so as to securely'hold the pump barrel in position.

The pump itself may be of any desired construction, except as hereinafter noted, and embodies the ordinary plunger rod 11, to the lower end of which the pistonl2 is secured, the leather of the piston being pressed outwardly against the wall of the .pump barrel or body by means of a coil spring 13, as shown, the pump rod being operated by means ofa rack 14: which meshes with aspur I inion 15 that may be turned by place to place asre acrank han 1e mounted at any desired point and operatively connected to the spur pinion by sprocket chain connections. As the means for operating the pump does not, in itself, form any part of the present invention, it is not illustrated, nor is it specifically described. It will be understood, however, that the pump embodies the ordinary measuring features, includin a register which is so constructed that it will measure the total number of gallons discharged and also measure by tens of gallons in succession, WlllCll 1s a feature incidental to measuring pumps for gasolene and similar fluids.

sleeve 18 is mounted for a vertically sliding movement, said'sleeve being adapted to abut against the bottom of the drum 3 and being formed with a corrugated or other lower edge, whereby free access may be hadfor the liquid to flow from the drum up-- wardly into the sleeve and thence into the pipe 17; The sleeve 18 is formed near its lower end with an upwardy facing valve seat 20 on which a foot valve 21 is adapted torest, the sleeve being provided at. its upper end with a corresponding'seat for another foot valve 22. Intermediate of its ends, the sleeve is formed with an annular flange 23, against which one-end of an expansion spring 24 bears, the other and upper end of the spring 24 reacting against a relatively stationary flange '25 which is formed on the interior of'the pipe 17. By this means, as will be understood, the

- sleeve 18 will automatically adjust itself so as to compensate for drums of varying heights. I I

26 designates a stuffing box and packing which is secured in the lowerendof the pipe In order to exclude dust and dirt from the interior of the drum when my improved device is applied'thereto, and is in o eration,

I preferably employ a cap 27 .0 leather or the like which is adapted to surround the pipe 17 and the opening 28 of the drum through which said pipe extends, the lower edge of said cap bearing against the top of the drum and the upper edge of the cap being secured to a collar 29 which fits snugly on the pipe 17 and which is pressed downwardly by means of an expansion spring 30 which bears at its upper end uponthe lower surface of the'pump base.

- Preferably, in order to prevent rain water or dust from collecting upon the top [of the drum 3and in order to provide a platform whereon funnels or {cans may be placed, I provide a cover 5. with a downturned marginal flange, as clearly illustrated in Figs. 1, 2 and 3, said cover being held in place by being interposed between the plate 5" which forms an integral part of the base bar 5 and the superjacent base flange 9 of the pump barrel 10.

From the foregoing description in connection with the accompanying drawings, the operation of my improved self measuring pump and attachments will be apparent.

In the practical use of the device, t e base 5 is secured to the rim flange 4 of the drum 3 and the pump body 10 is secured in place on said base with the pipe 17 inserted through the top opening 28 of the drum and with the valve carrying sleeve 18 resting at its lower end upon the bottom of the latter. Theliquid contained within the drum 5 may then be measured and dispensed as required and when the drum is empty, it is evident that the parts may be easily detached and applied to a full drum.

It is to be understood that my invention is not limited to the exact form of base 5, and various changes may be made in the construction and arrangement of this and other parts of the device without departing from the scope of the invention as defined in the appended claims. For instance, instead of using a base like that hereinbefore specified and illustrated in the correlated views of the accompanying drawings, I may use a base like that indicated at 5 in Fig.

.5 which is secured to the rim flange of the a head of the barrel by screws or similar fas- 17 to form a tight joint around the sleeve.

into the receptacle and connected at its upper end to the lower end of thebody, a sleeve mounted to slide longitudinally in the lower end of said pipe, a foot valve carried by said sleeve, a stufling box surrounding said sleeve and secured to the lower end of the pipe, and means tending to move the sleeve downwardly from the lower end of the pipe.

2. A pump of the character described including a body, an inlet ipe extending downwardly from said bo y, a vertically disposed sleeve mounted in the lower end of the body and formed intermediate of its ends with an exterior annular flange, the pipe being formed above said flange with an interior flange, an expansion spring surrounding the sleeve and bearing against said flanges, and a lift valve carried by said sleeve.

3, A pump of the character described, including a body, an inlet pipe extending downwardly from said body, a vertically disposed sleeve mounted in the lower end of the body and formed-intermediate of its ends with an exterior annular flange, the pipe being formed abovesaid flange with an interior flange, an expansion spring sursleeve, the lower end of the sleeve being corrugated, for the purpose specified.

4. A pump of the character described, including a base, a body connected to said base, an inlet tube connected to said body and adapted to extend down through the opening of a receptacle, a flexible cap surrounding said pipe and adapted to encircle the said opening of the receptacle, and an expansion spring pressing downwardly 'upon said cap, for the purpose specified.

5. A. pump of the character described, including a base in the form of a bar having downwardly facing recessed ends adapted to extend over the rim flange of a tank, set I screws carried by said ends for engagement with said flange, the base bar being provided with upwardly projecting studs, a pump body formed with a base flange having openings to receive said studs, pumping ele-- ments carried by said body, and an inlet pipe secured to the lower end of said body and adapted to extend downwardly therefrom through the base bar into a rece tacle.
