8 Claims.

This invention relates toa force feed oil can of the type in ,which an oil forcing plunger Vin thebase part of a noiZleQstructure is operated by manipulation of a lever on the can for the ejection of oil. `In' oil can` Structure, as for example such as disclosed in my Patent No. 1,542,896ydated June 23,1925, complete pumping structure is utilized including an oil Afeed pipe'` extending from the cylinder in the spout structure to the bottom of the can and with an inlet check valve therein and with the cylinder provided with an outlet valve, and, with such complete pump structure,

upon operation thereof by the manipulation of a pump lever on the can, oil may be pumped through the spout during any position ofthecan.

An important object vof yr'nyY present' invention is to simplify the construction and'reduce the cost of manufacture ofthe `can ,by eliminating parts, such as the inlet pipe and valve, and pro' viding a cylinder in the 'spout Structure which `can be readily lled 'by Atilting of the 'can and vfrein which, by `Inanipulati0h of a lever on the can, oil may be ejected through 'the spout in any lIO'QStin 0f the een.

A further 'object ofthe invention is to provide a cylinder Space in the" base ofthe spout structure with a plunger "therefor controlled byan actuating rod 'axiallyshiftable by the manipulation `of a lever 4on 'the can and with the arrangement such that, upon manual depression "of the lever, .theffmovenient vof 'the rod may be rapidly accelerated for quick movement of the "plunger for spurt ejection of oil' from the cylinder and out of the spout.

A.y further important 'object sto provide improved packing arrangement yfor 'the plunger ,actuating rod with the arrangement such that, after' each return ofthe can operating" lever, vthe lever will engage with packing structure to Af-Orc@ packiginaterial 'intimately `'agltinst the rod to thus`prevent leakage of oil frorn the can 'container tothe exterior'A along 'tl'ie'rod A'canv structure embodyingthe various features' Vof my invention are "disclosed on the 'a'c- 'coinpanying drawing in which `Figure 1 is "a 'side elevation ofthe can structure;

',Figu're Zisan enlarged plan view thereof; Figure 3 is an enlarged vsection on plane Figure 4 is an enlarged section on plane 4IV-IV,

n "Figure?2,4 with'the act'liatingzlever lil, normal poe extension but showing the operating lever depressed for shift of the plunger and ejection of oil through the spout structure.

The can shown comprises a c'over Il)r having flange' segments II for interlocking with flange segments I2 on the can body or container |23V to hold the edge of the container against a 'gasket I4 Aon the cover so as to form a tight seal when `the cover is applied. The cover is of sheet metal and has the extension I5 thereon forming the base part of the spout structure, the spout Vtip I6 being secured `in the neck part `I'IofY the extension I5. The extension I5 provides the cylinder space I8 for the cup shaped plunger |59. The bottom wall of the plunger has the inlet pase sag'eway 20, the metal of the bottom around the opening being upset t0 provide the `depending flange 2| and the upstanding inclined valve seat flange 22. A check valve 23, shown in lthe form, of a ball, normally engages the seat 22 tolclose the passageway 20, the ball being operable within a cage 24 which at its lower end is heldin` place by the seat uflange 22.

rAt one side of the cover extension I-5, a` guide: bushing 25 is mounted on the cover and secured thereto as by riveting asindicat'edat 2E. Slidably axially in this bushing is the plunger ac- 'tuating rod '21 which, at its lower end, extends through the opening 28 in the U-shaped bracket, 29, the rod being intimately engaged by the outer 'leg`30 of the bracket to hold the bracketin horizontal position, and notches 31|" inthe rod r'eceiving a split washer 32 on which the bracket seats. The inner leg 33 ofthe bracket hasears l `34 and 35 extending therefrom and having their upper ends rounded toengage the plunger ,along the opposite sides of the depending `flange'Zt of the plunger so that, when the rod 2'I is raised, the plunger will be shifted up inthe cylinder space I8, a spring 36 resisting upward movement of the plunger.

Extending across the can top I0 is .the operate.

ing lever 31 whichrhas'the substantially elliptical opening 38 therethrough l.for receiving the cover I5. A stiffening and strengthening llange 3S extends downwardly from the operating lever at its edges, and, `adjacentto the lever opening"38, the flange is extended downwardly to provide abutment ears 40 and 4I at diametrally opposite sides of the extension I 5 and Ain engagement therewith, `the lower edges of the ears engaginglthe cover III.

'The'end J42 of the lever 31 dene'cts or inclines downwardly for fengagement by the thunibor finger of vthe can' operator. The otnerenci ofthe lever extends over the bushing 25 and has the opening 43 therethrough for receiving the upper end of the rod`21 which terminates in a head 44 above the lever so that when the lever is rotated by pressure on the finger end 42 thereof, the rod 21 and the bracket 29 thereon will be raised for upward shift of the plunger in the cylinder. When the operating lever is released, the spring 36 will shift the plunger down against the bracket 29 for return `of the rod to its normal position with its head againstlthe lever 31; fTo prevent leakage of oil from the container to the exterior thereof along the rod 21, packing material 45 is provided and held in place on the outer end of the bushing by a sheet metal cap 46 which frictionally engages the bushing, the outer end of the cap being frusto-conical so that upon downward pressure thereon the packing material will bef forced radially into intimate engagement with the rod. The packing cap forms a stop for the operating lever 31 when the lever is swung back to normal position upon downward shift of the rod 21 by the force of the spring 36 so that, after 1 each release of the'operating lever, the lever will tap the packing cap to shift the cap down against 'the packing to take up any looseness of the packing and thus keep the packing intimately in en- 5 gagement with the rod to prevent oil leakage.

As the lever 31 receives the extension I5 through its opening 38, the axis X of rotation of i the lever is substantially in the vertical plane of 'lthe minor axisof the opening. The ears 40 and `(4| of the lever have longitudinally extended fulcrum edges for engagement with the cover to the right of the axis X, the distance of these surfaces from the axis X increasing toward the rear'ends of these surfaces, as clearly shown on Figure 3. With this arrangement, when pressure is exerted -on the end 42 of the operating lever, the lever will be rotated on its axis X, the ears 46 being swung :forwardly with the lever to bring their fulcrum -tedges 41 progressively into engagement with the .fcover I resulting in raising of the lever at its axis while it is being rotated.l This rotary and bodily movement of the lever is limited by the engagement of the outer edge of the lever opening 38 with the extension I5, as shown on Figure 5, the rounded heels 48 of the fulcrum edges being then in engagement with the cover.

. The can body may be provided with a handle,

but for manipulation of the can a handle would not be necessary for the operator may grasp the can body or container in the hand and with one of his fingers operate the lever 31. Owing to the inclined end 42 of the lever, pressure thereon will have a vertical downward component, and a radial inward component toward the lever axis. As the lever is being swung down by the finger, 4the radial pressure -component will increase whereby the heels 48 of the fulcrum edges will be quickly moved toward the vertical line of the axis X forV acceleratedk movement of the plunger in rcylinder I8. Furthermore, as the lever is being icreases, and the distance between the finger engaged end of the lever from this point correspondingly decreases so that the outer end of the lever is further accelerated in its movement for r4shift of the plunger into the cylinder.

When the can is to be used, it is first tilted Vsuiiiciently for unseating of the valve ball 23 for ow of oil from the can body into the cylinder I8.and then, when n; the lever 31 is operated, the shift of the plungerl in :2,340,480 L f @if f the cylinder will exert pressure on the oil for discharge from the cylinder out througlh the spout tip I6, the accelerated movement of the outer end of the lever in the manner explained exerting accelerating pressure against the oil in the cylinder for rapid or spurt discharge from the spout.

When the cylinder I8 has been lled, the can may be operated in its normal or vertical position by manipulation of the lever 31 for forced ejection of oil from the spout, the force of gravity from the can body through the cylinder and spout, or, by operating the lever while the can is inverted or tilted, spurt pressure may be applied, the resistance of iiow through the more or less restricted spout tip causing sufficient pressure in the cylinder, when the plunger is operated, to hold the valve '.ball 23 seated against the force of gravity. f

I have Vthus produced a force feed oil can of simple and economically manufactured and assembled parts which may beV easily operated'for forced feed of oil from the can container in any position of the can and without the need of a feed pipe extending to the bottom of the container. All the operating parts are mounted on the cover structine which can therefore be readily applied to can containers of various capacity,

I have shown a practical ,and efcient embodifment of the features of my invention, but I do not desire to Ibe limited to the exact construction, arrangement and Aoperation shown and described as Achanged and modifications maybe made without departing from the scope of the invention.
