PUMP FEED OIL CAN Filed April 29; 1943 uks r4 vs L/DSEEN Patented Feb. 1, 1944 means UNITED STATES PATENT OFFICE PUMP FEED OILCAN GustaveLidseen, Chicago, 111. Application April 29, 1943, Serial No. 484,993

3 Claims.

My invention relates to a pump feed oil can of the type in which, by the manipulation of a pump lever at the top of the can, oilis pumped from the can for flow under pressure through and out of the spout. In my Patent No. 1,542,896, dated June 23, 1925, I show a can of this type, and in general the object of the invention is to provide a more practical and more efi'icient operating mechanism for pump structure such as shown inmy patent.

More in detail, one important object is to provide an arrangement in which the can handle or rip is secured to and extends from the can cover and provides a fulcrum seat for the thumb-operated pump lever.

A further object is to provide improved means for connecting the pump lever with the pump plunger.

A further important object is to provide an arrangement in which the pump lever has a passageway therethrough receiving the base of the spout structure to be guided thereby and to be held in proper fulcrum engagement with the handle.

Another important object is to provide an arrangement in which a pump rod extends through and is guided by the can cover and is connected at its outer end with the pump lever and at its inner end with the pump plunger.

Still another object is to provide improved means for preventing leakage of oil from the can to the exterior thereof along the pump rod.

Other and further important objects of the invention will be apparent from the disclosures in the specification and the accompanying drawing, in which drawing:

Figure 1 is a side elevation of my improved oil can;

Figure 2 is an enlarged diametral section of the can cover and upper part of the can body, showing the pump mechanism in normal position;

Figure 3 is a view like Figure 2 showing the pump lever depressed for pump operation and discharge of oil from the spout;

Figure 4 is a plan view of the cover structure; and

Figure 5 is an under side view of the cover.

The cover structure I is of sheet metal and has a number of helical extending flange segments l I for engagement with flange segments l2 on the can body or container l3 for holding the can intimately against the sealing gasket l4 on the cover. Extending upwardly from the cover is the cylindrical housing I which may be an integral part of the cover and which at its upper ears 32 and end has the contraction or neck It to which the lower end of the spout I1 is secured.

The handle or grip structure l8 for the can has its upper end [9 extending along the top of the cover and terminating in a collar 20 which receives the housing IS. The handle structure is secured to the cover as by welding, or riveting by a valve ball 2! under pressure of a spring 28.

Extending diametrally across the top of the cover is the pump lever 29 which has the elliptical opening 30 for receiving the housing 15 above the handle collar 20. This pump lever is of sheet metal and has the surrounding stiffening and strengthening flange 3| which, adjacent to the opening 33 which are in fulcrum engagement with the upper edge of the collar 20 on the handle, the engagement of the extension IS in the opening 30 holding the lever with the ears in such fulcrum engagement with the collar. 7

Atits inner end the pump lever has the opening 34 for receiving the pump rod 35 which at its upper end has the abutment head 36 engageable by the pump lever. The rod extends down through a guide bushing 31 secured to the cover 10, as by riveting, this bushing being preferably of steel. A sealing gasket or packing 38 receives the rod above the bushing, a cap 39 on the bushing holding the packing in place against the bushing end. The head of the cap is preferably frustoconical so that when the cap is forced down on the bushing it will compress the packing intimately against the rod to seal against the escape of oil'from the can body outwardly along the rod, the cap, after setting on the bushing, being held in position as by deflection of a part thereof into the side of the bushing, as indicated at 40.

Connected to the inner end of the pump rod 35 is the Ushaped bracket 4!. The rod extends through the hole 42 in the bottom wall of the bracket so that the outer wall 43 of the bracket will engage the rod, the rod having notches 44 in its end for receiving a split washer 45 against which the bracket seats. Extending from the opposite side of the inner wall 46 of the bracket are opposed ears 41 and. 48 which extend up 30, is extended downwardly to form along the opposite sides of the discharge pipe 24, the ears at their upper ends being rounded for engagement with the bottom wall of the plunger 23. A compression spring 49 between the plunger and the head of the cylinder 22 tends to hold the plunger and the pipe 24 down for engagement of the plunger bottom with the bracket ears 4'! and 68 and with the head 36 of the pump rod against the top of the pump lever 29;, as shown on Figure 2. When the pump lever is now swung down, the pump rod is raised to lift the bracket 4! for upward movement of the plunger in the cylinder 22. During such up? ward movement, the check valve 25 at the lower end of the pipe 24 will be closed by the oil pressure and oil will be forced out of the cylinder past the valve 2'! and into and out of the spout H for application to the bearing or other structure to be oiled. Upon release of the pump lever, the spring 49 will return the plunger and the pip ,4 ewh ar llr t e alve .2 bei then closed by e set- 1s the. the. che k a e eeehihe t r e enti h ei il t the 12 .12 4 for efi li e t e nd r 2.2- h ie e i Whieh il is x l ed em h n zzle, de en o h im 9 2 555 .13 p l ed. 9. t P 9? level when pressed downwardly.

With the handle structure secured to and ex.- tending from the cover structure and the com paratively wide pump. lever receiving the cover extension IE to. be guided thereby for fulcrum en ge ent wit the hand e, a s r assembly results which will rotect the pum lever against displacement and will at all times guide the lever; for efiicient reciprocation of the pump rod for operation of the. pump mechanism for discharge of oil from the spout. The pump rod by being guided by the bushing on the head and operating'thro, gh the. bracket will insure axial operation of the plunger in the cylinder without binding, so that the oil discharge struc} ture will operate easily and efficiently at all times.

I have shown a practical and efificient embodimentof my invention but I do not desire to be limited to the exact construction or engagement shown and described as changes and modifications may be made without departing from the scope of the invention.
