Application flied July 21,

To all lv/0m it muy con Be it knovn that l, .l N l-l. Contains, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in .Pumps, of Whichthe following is a. specification.

My invention relates to pumps of the type generally utilized for drawing relatively small quantities lof liquid from a storage tank; the principal objects of my invention being to generally improve upon and simplify the construction of existing types of similar pumps, to provide a pump that is of relatively simple structure thereby permitting it to be manufactured at relatively low cost, and further to provide simple and eliicient means for catching and retaining all drip or overflow from the pump spout or the container into which the liquid is discharged, and for returning said drip and overflow to the storage tank.V

Further objects of my invention are to provide simple and efiicient means for locking the pump While not in use, thereby preventing the unauthorized use of the pump, and yfurther to provide pump `of the character described with means for preventing foreign substances, such as sand, dust, 'and Water rfrom entering the return tube and passing into the storage tank.

-Vllith the foregoing and other objects in view7 my invention consistsin certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Fig. 1 is an elevational view of the pumpv with parts thereof ,in section.

Fig. 2 is a vertical section ,taken approximately on the line 2 2 of Fig. 1.

3 is a horizontal section taken approximately on the line of 1.

Referring Vby numerals to the accompanying drawings which illustrate a. practical embodiment of my invention, l() designates the cylindrical body of the pump, the same being preferably formed from a section of metal tubing of proper size, and arranged von he ends ofsaid cylindrical body is an upper head l1 and the tower head 1Q, the same being .connected and maintained in assembled relation by suitably located tie rods 13.

Secured in any suitable manner to the lower head l2 and depending therefrom is a preferably of .the d.W

short tubular housing lll from which projects laterally a tubular neck 15 that terminates vin a. horizontally disposed pan 16. This pan is of disc-like form and is provided with an unstanding marginal flange 17. Beinovably .arranged Within the pan 16 is a section 18 of reticulated material', such as Wire netting, the same serving as a support for the containers that receive liquid discharged from the pump spout. Hinged to pan V16 and preferably ata point adjacentlto tubular member 14 is a cover platev 19 for the pan 16, and arranged on the underside of said cover plate adjacent to its edge is a gasket or packing member 20 thatis adapted to rest directly on top of flange 17 and provide a. practically air and dust proof joint when the cover plate is closed.

rllhe cover plate19 is retained in lclosed position upon pan 16 bya suitable latching device 2l that is preferably located diametrically opposite the hinged point of saidl cover plate. The lovver end of tubular member lllis directly connectedL to the upper end of a tube 22 that extendsV downwardly `and thence laterally to the lower` end of a liquid storage tank (not shown).

l Formed integral with or fixed tothe lower portion of head l2 and positioned in the upper portion of tubular` member 14 -is a cage- 25 to Which is connected the upper .end of the pump tube 26 that v extends downtva-rd` through the verticalgfleg of tube- 22, Aand arranged in the upper portion of said cage 25 an u Wl dly open-in inlet checkvalve 28 type. Arranged for reciprocatory movement .Within the cylindrical vbody '10 lof the pump is a piston 2S) carrying on its periphery a cup packing member 30, and-said piston being provided with one or more openings 31 that are normally cloed by an upwardly opening check valve 32 preferably of the disc type. Connected in an y suitable manner to the upper end of the piston 29 is the lower end of a pump rod that is arranged kfor reciproca-tion :through a gland or stuffing box S-l on lthe top of `head 1l. Pivotally connected to the upper end of pump rod v33 is one.

end of a pump operating-lever' thatis provided on its lower yor outer end With a handle 35, and there being a ring 37 formed on the loiver end of said handle. Pivotally connected to a bracket that projects outwardly eat 27 upon i Aich normally rests slow movements.

from lower head 12, is the lower cud of a link 38, the upper end of which is connected to the intermediate portion of lever 35 by a rel-Y V atively short link 33, Pivotally mounted on the lower portion of link 38 is the inner end of a loop 39 that is adapted to receive the ring 37 on the lower end of lever 35 when the latter occupies a substantially vertical position, as illustrated in Fig. 3. When ring 37 is thus engaged through loop 39,'the operating parts ofthe puinpmay be effectively locked by the application of the hasp of a suitable padlock Ii() through theV ring 37. Screw seated in the upper head 11 is the inner end of a tubular spout 41, the outer end of which is bent downwardly so that it occupies a position a suitable distance above the center or" pan 16.

The operation of my improved pump is as follows: v

Lid or cover plate 19 is swung upward so as to uncover pan 16, and the container that is to receive the liquid discharged fromA spout 41 is placed on the reticulated member 18. Handle 36 is now manually engaged and lever 35 is manipulated so as to reciprocate piston 31 within the pump cylinder, which action draws liquid from the storage tank upwardly through tube 26, and which liquid after passing through the alternately opening check valves 28 and 31 passes through the upper portion of the pump cylinder and discharges through spout 41 into vthe receptacle positioned on pan 16 Any overflow from this receptacle and likewise any drip from the spout l1 will pass from pan 16 into tubular member 15, and from thence said drip or overflow liquid will pass back to the storage tank through pipe 22` After the receptacle has been removed yfrom the pan 16, cover plate 19 isswung downwardly on to the top of said pan thereby effectively preventing foreign matter, such as dust, water and the like from entering the return tube 22 'that leads to the storage tank. the pan 16 is such as to prevent relatively thin liquids from splashing outwardly over the edges of' the pan, and likewise ,for nreventing relatively heaiy liquids from piling up and overflowing as a result. of their Further, the capacity Vof the return tube 22 is much greater than the capacity of tube 26 that carries the liquid to the pump, and which arrangement prevents the drip pan from overflowing in the event that the flow of' liquid'from the pump is directed from the nozzle into the drip pan.Y Such construction insures the quick return of all characters of liquid to point of storage.

The depth and general form of lWhile my improved pumpV may beadvantageously employed wherever Y relatively small quantities of liquid are periodically withdrawn from a storage tank, it is'par-A ticularly adapted for use for the handling of fuel, lubricating and illuminatingv oils, and its use in connection therewith affords a relatively high degree of safety, economy,

cleanliness and efficiency'.V y

y lt will be understood that-minor changes in size, form and construction of the various parts of my improved pump may be made and substituted for those herein shown and described without departing from the spirit ,of my invention, the scope of which is set forth in the appended claims.` l claim as my invention:
