Fig. 7 is a horizontal section taken on the line 'I-1 of Fig. 5 as indicated by the arrows; and

Fig. 8 is a vertical section taken on the line il-G of Fig. 5 as indicated by the arrows.

Referring rst to the embodiment of the invention shown in .Figures 1, 2, 3, and 4, there is provided, a container il, having a reduced mouth at its upper end provided with external screw threads 9a and an inturned ange 9b at its top. There is also provided a cap Ill, having a circular skirt portion Illa, provided with internal screw threads for releasably engaging the external screw threads 9a at the mouth of the container s. The cap I0 has a lateral projecting portion Illb of fiat construction, the sides of which taper toward the end of the projecting portion as 'best shown in Fig. 2. It should also be noted that the edges Illc, of the cap I0 above the skirt lila project outwardly beyond the skirt for a purpose presently to appear. The cap Il] also has an upwardly extending portion Illd, provided with external screw threads at its outer end, whereby a spout II may be attached to the upwardly eX- tending portion Illd, as by a suitable fitting, t2. In the form shown, the upwardly extending portion IIld is tilted at an acute angle relative to the body portion of the cap I0, but it will be understood that the portion Id may be extended at any angle from the body portion of the cap so that a vertically extended spout, for example as shown in Fig. 5, may be applied thereto, or a spout 2 Claims. (Cl. 222-385) l disposed at any angle fill* may be applied thereto. A passage is formed'through the body of the cap Ill and through the upwardly extending portion IUd, whereby communication is afforded through z the cap with the spout I I.

A conduit I3 is"A screw ythreaded into the lower part of the cap, the passage through the body ci" the cap being enlarged and tapped to receive the upper end of the conduit I3. This conduit I3 is preferably provided with a double bend as shown in Fig. 1, and runs down toa point near the bottom of the container 9, somewhat forwardly of the vertical longitudinal center line of the container.

The conduit I3 supports a pump structure within the lower part of. the container Sl. This structure includes a pump body It, forming a pump cylinder I4a within which a pump plunger I5 works. An inlet I4b into the lower end of the cylinder Mais provided and this inlet is controlled by a ball valve I6, spring pressed into engagement with its seat by a spring I 1 reacting between the ball I6 and the lower end of the pump plunger I5. The pump body I4 vis also provided with a lateral outlet I4c at the lower end of the pump cylinder I 4a, and this outlet is controlled by a ball valve I8, disposed within a horizontal bore idd in the pump body and pressed into engagement with its seat by a spring I9, reacting between the ball valve I8 and a screw 2l] closing the end of the bore I4d. The lower end` of the conduit I3 screws into a lateral extension of valve body Hl above the bore Idd and vthis lextension is provided with a vertical bore I 4e whichaiords vcommunication lbetween the bore Ifd andthe conduit I3.

The conduit I3 is provided with a cross bore slightly above the level of the pump cylinder lila, and fitting within this cross bore is a small tube 2 I, which is sealed at its ends to the sides of the conduit I3 so that oil or other fluid within the container 9 cannot seep into the conduit i3 through thebore within which the tube 2| is located.V A pivot pin 22 fits through the small tube 2I and acts as agpivot for a double arm lever i 23. lConnected at one end, by a pivot 24 to the double arm lever 23 Vis a short pitman 25, having a ball at its lower end fitting within e. ball socket I5crl at the upper end ofthe plunger l5. Thus, the lower end of the pitman 25 is capable of universal movement relative to the plunger i5.

Connected by anotherpivot 25 to the opposite end of the double arm lever` 23 isa rod 21, which projects upwardly through a small opening ite in the cap I0 and this rod is provided with an enlarged head atits vupper end. A wiper gasket 28 surrounds the rod 21 immediately below the opening Ille and this gasket tends to wipe the upper portion of the rod clear of oil as the rod is raised. A coil spring 29 ts around the rod 27 and reacts between the gasket 28 and the pivot pin 26. In the form of the device as shown, the three pivot pins 22, 24, and 26 are shown as being cotter keys but any type of pivot could be substituted therefor.

The cap Ill'carries agasket 'which normally rests onfthe flange 9b ofthe container '9 so-that the cap will form a tight seal with the mouth of the container.

Overlying the major portion of the cap and the extension |b thereof is a sheet 3|, this sheet being apertured to receive the upwardly extending portion |0d of the cap and .the edges of the sheet being crimped downwardly and portions thereof inwardly to embrace the extended rim lilc of the cap and the extension Ib thereof. The edges lof thesheet l0 .are lbent inwardly-on themselves, outwardly strom :the extension 0b 4to form a handle 31a, ithis .handle outwardly :from the extension |0b being. .first idownturned and then reversely curved as shown in Fig. 1. The metal of the sheet3|.:iscutltorform Aa .tab 3|b and this tab is lswung Aupwardly `and a-:channel shaped slot 3| c is formed .thereimwhereby the tab will form a fulcrum .ffor .-a-channel -shaped trigger lever 32. .This .trigger lever is :formed with a reverse curve-:fas ybest .seen in Fig. l. The iianges at the .sides of the lever-.are ireduced in width slightly at the flower eend fof `the lever. At this point the lever is provided with a Vslot 32a which receives the vupper part-"of the rodv `21 below the enlargedhead thereof. The upperpart of the trigger lever y32 A`is Asilattened fand ,rounded so as to form a convenient thumb vcontacting portion when .the ywholefoilccanis-supported yfrom the handle -3|a by-.one hand @of fthe operator.

When the oil-Canis .so heldvfandsthe upper part of the trigger lever 32 is depressed -by the -thumb of the operator, the triggerfllever 432 -will .'have a sliding action relative to lthe tab 3|b. as the rod 2l is raised .by Athe .normally lower .portion of the lever. Of (course, asthe zrod 21 ris raised against the ltension ofthe spring `29, the lever 23 will be swung .so .as to `depress the pitman 25, thereby depressing thepump plunger |15 and ejecting oil cont-ained inthe ,pump :cylinder |4ll through the `outlet rHc, :into the bore Md and bore 4e, causing the -oi1 -tovbe .forced upwardly through the conduit i3, rpassage through .the 'cap i6 and spout .As-thevtrig'gerlever 32 `is-released by the .thumb .of .the -nperator 1the Y spring 29 will return the parts `to the .position shown in Fig. 1, thereby .causingthe ;plunger |.5 A.to move upwardly, closing Athe .valve 5|8 land `opening the valve |6 `and .sucking a .fresh supply of oil into the pump .cylinder lla.

The ball and .socket joint connecting the pitman 25 with the pumpplunger |5 4allows -for proper movementof the -partswithout a .loose connection and the use of `the .small tube-2| mounted in .the conduit .I3 .permits the lever 23 to be readily supportedfromthe conduit .i3 without seepage of oilinto the-conduit .|l3.

In practice '.thefcap `AIll .will :be .die-cast in one piece and thepartsare thus very easilyassembled with a minimum of-labor.

Referring now to .'Fig'uresv, 6, .7 ,and l8 of -the drawings another embodiment of "the invention is shown which .includes-.many ofthe featuresof the device illustrated in`Eigures` 1 .to 4. .In'the device shown in Figures 5 'to 8,1 :a lcontainer 33 is provided, having a mouth with external screw threads to which there is threadedly secured a cap 34, there being a gasket 35 interposed between the top of the container 33 and the cap. Fitting loosely through a central aperture in the cap 34 is a fitting 36, having a shoulder of polygonal shape to receive a wrench above the cap and below this shoulder the tting 36 is reduced and screw threaded to pass through the aperture in the cap and Ato receive below the same a gasket 3'! and nut 38. The portion of the fitting 36 below the shoulder is cut away and 'flattened at its sides to correspond to the shape of the aperture through the cap 34, whereby parts attached to the tting 36 may be properly aligned relative to the spout which will be later described. Above its shoulder the tting 36 is provided with exterior screw threads to receive another `iitting 39 securing a spout 49 in position on the tting 36. Of course, the tting 36 is provided with a :passage therethrough communicatlng with the spout 40. The -passage in the lower part of the tting 36 isenlarged and tapped to receive the screw threaded upper end ol a conduit 4|, which projects down into the container 33 and carries at its lower end apump structure. The said pump structure includes a pump body 42 forming a pump cylinder v42a within which works a pump plunger 43. An inlet 12b is provided in the lower part of the pump cylinder 42a and this Iinlet is -controlled by a ball valve 44, pressed into vposition by a coil spring 45 reacting between'the ball 44 and the pump plunger 43. As in the case-of the pump structure previously described, theretis an `outlet 42o formed in the lower part of the pumpcylinder 42a and this outlet is controlled by a ball valve 46 disposed within ya horizontal bore 42d in the body 42, `the ball 46 being normally held into engagement vwith its seat by a coil `spring 4l, reacting between the ball -46 and a screw 48 which closes the bore 42d. The bore 42dcom municates with a vertical bore 42e in the pump body 42 and the lower end of the conduit 4| is screwed into a portion-of the body 42 immediately above the bore 42e, so that communication may be aiorded through the bore v42e with the lower end of the conduit 4|.

The body 42 is slotted at -4'21 near its upper ,end to 4receive a two-part lever 49 pivoted in apair of projecting ears '42g formed on thevalve body 42 at the two sides of the-slot 42f. The `lever 49 has at one end, the upper end of a pitman 50, pivoted thereto, the lower end-of this pitman being ball shaped to fit -within a .socket at the upper end of the plunger 43. A rod 5| is pivoted to the other end of the lever 49 and this rod projects upwardly through a wiping gasket 52 and through an aperture in the cap 34 .and is provided at its upper end with'anenlarged head. Avcoil spring 53 surrounds lthe rod 5| and reacts between the gasket 52 vand the pivot connecting the lower end of the rod to the lever-49.

Spot welded or otherwise secured -to the top of the cap -34 is a handle member'54 and the inner end of this handle member is notched to -embrace the cap 34 at two sides of the tting 36. A tab 54a is bent upwardly from the notched portion and this tab is provided with a `channel shaped slot therein, -receiving trigger lever 55 of -similar construction to trigger lever-3f2 previously described. The lower 'end'of the trigger lever 55 is apertured to receive the lupper part-of the rod 5| below the enlarged head thereof. The handle member l54 is curved as Ishown in Fig. '5, so as to form a proper support for the hand of the operator without permanent engagement with the side of the container 33.

The operation of the device shown in Figs. to 8 will be readily understood. The construction of the cap 34 and fitting 36 together with associated parts is such that the cap 34 may be merely a stamping and the parts can be assembled readily without soldering or welding operations.

While the devices of the invention are intended primarily for use as hand oilers, it will of course be understood that the structures employed may be used in dispensing any kind of iiuid, such as water, cream and all kinds of lubricants.

It will be seen that highly ecient hand oiler structures have been provided. It will of course be understood that various changes may be made in the form, details, arrangement, and proportions of the Various parte without departing from the scope of the present invention which, generally stated, consists in the matter shown and described, and set forth in the appended claims.
