MEASURING- AND DISPENSING PUMP.

Application filed August 6, 1924. Serial NO. 730,340.

My invention relates to an improvement in a liquid dispensing appliance, and more particularly in an oil dispensing and measuring pump. In general my object is to prvide a pump assembly which may be readily attached to barrels or containers of dif ferent sizes. and in which an extensible intake pipe is adapted to be inserted into the barrel to permit the contents of the barrel or container to be withdrawn from the bottom thereof, the said extensible pipe being particularly constructed to promote a free uninterrupted discharge; to facilitate the assembly and adjustment of its parts; to maintain air tight joints: and to assure reliable and correct measuring and dispensing operations of the pump.

In the accompanying drawings. Fig. 1 is a sectional view of a medium-sized metal barrel and a side elevation of a measuring and dispensing pump attached to the head of the barrel. the pump being provided with my improved extensible intake tube extendin to the bottom of the barrel.

ig. 2 is an enlarged view of the intake tube showing parts thereof broken away and in section to disclose the details of construction. Fig. 3 is a perspective view of the bottom end of the tube showing the 0 outer tube raised to its limit upon the inner tube and the gland member exposed to permit it to be removed or rotatably adjusted.

Fig. 4 is a perspective view of the lower end of the inner or main tube, and Figs. 5

and 6 are similar views of the washer and gland member, respectively.

. Fig. 7 is a perspective view of the lower end of the outer tube or extensible sleeve.

The invention involves the use of a measuring and dispensing pump of any suitable type'or kind. As an exemplification, I show in Fig. 1 a lift pump 2having a crank handle 3 and associate means adapted to reciprocate a lift plunger 4 within the pump cylinder according to known practises. The

liquid is discharged through a nozzle or spout 5, and an overflow or drain pan 6 is stationed beneath the spout and attached to the base member 7 of the pump. Member 7 is in the form of a screw coupling to permitthe pump to be detachably connected with a screw-threaded bung opening 8 in the head or side of a barrel 9 or other container. Generally, steel barrels or drums are used. for shipping and storing refined of said tube.

oils, and it has become a common practice to dispense the oil direct from such barrels by means of pumps attached to the barrel, the intake for the pump being through a pipe or tube aflixed to the base or bottom of the pump. The intake tube must extend to the bottom of the barrel to permit the entire contents to be emptied; and to accommodate different sizes of barrels the intake tube is usually made telescopic or extensible. Also the joints of this telescopic intake tube must be kept air-tight to obtain etiicient and correct measuring and dispensing results. v

My invention resides in the details of construction of the telescopic intake tube. Thus, a main tube or pipe 10 is attached to the lower end of the pump 2 or coupling pressible position between a metal washer 13 and a rotatable gland member 14. The

end portion of pipe 10 is reduced in diameter to provide an annular shoulder 15 adapted to seat the washer, and the reduced portion 16 is screwthreaded to permit the gland member to be detachably connected therewith and to be rotated thereon to compress and expand the packing. The upper end of the gland member is also chamfered or beveled inwardly to cause the packing to engage tightly against the screw-threaded reduced portion 16 and provide an air-tight joint at this place as well as at the inner wall of the outertelescopic tube or extensible sleeve 11. Gland member 14 is also formed with an external shoulder 17 intermediate its ends to permit the outer telescopic tube to have stop engagement therewith, said tube having notches 18in its edge and bent corners 19 adapted to engage shoulder 17 to limit the upward movement The retired position of shoulder 17 permits sleeve 11 to be raised beyond the reduced end of the gland member as shown in Fi 3, thereby exposing this part of the lan member to permit it to be gras ed y hand or gripped by a tool and rotate either to compress the packing or to remove the gland member to separate the parts. The upper end'o'f' sleeve 11 is flanged inwardly at 10 to engage and slide upon tube 10; and flanged portion 10 also serves as a stop and coo crates with washer 13 to limit the outwarc or extensible movement of sleeve 11. To remove sleeve 11 it is necessary to first remove the gland member, washer and packing, and access to sleeve 11 may be had by detaching the pump from the barrel and withdrawing the depending tube through the bung opening which isof slightly larger diameter than the smooth and straight sleeve 11.

What I claim as my invention, is 1., A telescopic intake device for a measuring and dispensing pump, comprising a pair of telescopic tubes, the inner tube having a removable and adjustable gland member and acking aflixed to its lower end and movable in its entirety through the outer tube, and the outer tube being open at its bottom and slidably sleeved over said inner tube and having a limiting stop adapted to permit said gland to project partly through said open bottom. v 2. A telescopic intake device for a measur mg and dispensing pump adaptgl to be connected to a -barrel,comprising a pair of telescopic tubes open at their corresponding ends, and a packing gland adjustably secured upon the inner tube in contact with the inner wall of the outer tube, said gland having a wrench engaging extension adapted to be projected beyond the lower end of the outer tube to permit adjustment and removal of said gland.

- 3. A telescopic intake attachment for a measuring and dispensing pump, comprising a pair of telescopic intake tubes, a gland member and packing aflixed to the lower end of the inner tube and slidably engaged with the inner surface of the outer tube, a stop said gland member is lowered through the open bottom of the outer tube.

4. A telescopic, intake attachment for a measuring and dispensing pump, comprising a pair of telescopic intake tubes, the inner tube having a reduced screw-threaded portion at its lower end, a washer and packing sleeved oversaid reduced portion, a gland member screw engaged with said reduced portion having an inwardly beveled end engaging said packing, and the outer tube open at its bottom end being sleeved over said inner tube and said packing and having inwardly extending portions at its upper and lower ends adapted to come into stop engagement with said washer and gland member, the latter having a co-operating stop spaced apart from the bottom end thereof to permit the gland member to project beyond the bot-- tom end of the outer tube.

A telescopic intake device for a measuring and dispensing pump, comprising'a pair of telescopic intake tubes, the inner tube having a gland member and compressible packing at its lower end engaging the inner sur face of the outer tube, said outer tube having a notched lower end and an inwardly extending stop flange at its upper end, and bent inwardly where notched to engage said gland member and to limit the movements of the outer tube in opposite directions upon the inner tube.

In testimony whereof I aflix my signature.

CHARLES SPAETH.
