VERNON AMOS WEAVER, OF THREE HILLS, ALBERTA, CANADA.

OIL-CAN.

T 0 all whom it may concern:

Be it known that I, VERNON A. IVEAVER, a citizen of the Dominion of Canada, residing at Three Hills, in the Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Oil- Cans, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in oil cans used by machinists, engineers and others, in lubricating machinery; and it relates more particularly to an attachment for an oil can of this character whereby the life of the can will be materially prolonged.

In hand oilers of the character above mentioned the spring bottoms soon lose their resiliency so that it is difiicult to eject the oil from the can.

It is the object of the present invention to provide a simple, inexpensive and practical attachment of this character which may be readily applied to oil cans now in general use, and which will take the place of the resiliency of the can bottoms so that the cans can be used after such bottoms have lost their original spring or resiliency.

With this object in view the invention consists of an adjustable protecting and supporting ring-member, and a bottom-actuating spring, the latter being of peculiar construction whereby it may be easily applied to any kind of an oil can.

lVith the above and other objects in view the invention consists of a novel construction, combination and arrangements of parts hereinafter fully described in the claims, and illustrated in the accompanying drawings in which Figure 1 is a sectional view through an oil can showing the application of the invention thereto. Fig. 2 is a plan view partly in section of my improved protecting and supporting rim. Fig. 3 is a perspective view of the band from which the ring is formed. Fig. 4 is a detail perspective view showing the overlapping ends of the band or rim and the adjustable connection of said ends, and Fig. 5 is a detail sectional View through the bottom of the can, and the spring attaching and adjusting means.

Referring more particularly to the drawing, 1 denotes the body of an ordinary 1nachinists oil can, the same being cylindrical in shape and having at its top the usual discharge tube, and at its bottom an annular Specification of Letters Patent.

reinforcing bead or rib 3. The bottom 4 of the can is made of resilient metal so that when it is pressed inwardly oil will be ejected from the tube 2. For the purpose of restoring or replacing the resiliency of the bottom 1, a longitudinally curved leaf spring 5 is provided. This spring is of such length that its ends bear upon the outer face of the bo tom 4 adjacent the bead or rib 3, its central portion being apertured to receive an adjusting screw 6. The latter has at its lower end a milled head 7, and its upper screw threaded end projects through the central opening formed in the bottom 4 of the body of the can and has upper and lower clamping nuts 8, 9 which adjustably secure it to said can bottom. The lower nut 9 engages the outer or under face of the bottom l, while the upper nut 8, which is in the form of a cap nut has a leather washer interposed between it and the upper face of the bottom 4, as shown more clearly in Fig. 5. A flat faced projection 11 is provided on the upper side of the nut 8 for engagement by a socket wrench having a long stem or shank adapted to be passed through the reduced neck of the can body 1. Owing to this construction it will be seen that the screw 6 secures the spring 5 to the bottom 4, and that by adjusting said screw, by means of the nuts 8, 9, the tension of the spring 5 may be varied so that a greater or less amount of oil will be discharged from the tube 2 when the bottom 4 is pressed inwardly.

For the purpose of protecting the spring attachment above described, and also providing a supporting base on which the can may rest, I provide an improved detachable and adjustable rim 12. The latter is in the form of a metal strip or band bent into circular or ring-like form, and having its over lapping ends adjustably united. The upper edge of the ring or band 12 is preferably offset in an inward direction to provide a shouldered portion 13 which engages the outer face of the side wall of the body 1 and bears against the bottom rib 3, as shown more clearly in Fig. 1 of the drawings. To prevent the can from slipping downwardly in the rim or band 12, supporting lugs or ears 14 are provided on the lower portion of said band for engagement with the bottom 4. Said lugs 14 are preferably formed integral with the band 12 by making U-shaped slits in the same and then bending the portions or tongues formed by said slits upwardly or inwardly as clearly shown in Figs. 1 and 8. The adjustable connection between the over lapping band 12 is preferably effected by forming on one end of said band flexible tongues 15, 16 adapted to be passed through any of the longitudinally arranged series of openings or slots 17, 18 formed at proper points in the band adjacent its other end. The tongues 15, 16 after being passed through the openings or slots 17 l8 respec tively are bent upon themselves, as indicated in Fig. 1, thereby securely fastening the rim or band 12 on the bottom of the body of the can.

From the foregoing it will be seen that the invention provides an exceedingly simple and inexpensive attachment which may be readily applied to different kinds and sizes of oil cans now on the market, and that when applied to an oil can whose bottom has lost its spring or resiliency it will render the can as good as new and materially prolong its life.

- Having thus described the invention,what I claim is:

1. The combination of an oil can having an apertured bottom, a longitudinally curved leaf spring having a central opening, and ends to bear against the outer face of the bottom of the can adjacent to the edge of said bottom, a screw extending through the apertures of the spring and bottom and having a head at its lower end to bear against the spring, upper and lower nuts arranged upon the threaded portion of the screw on opposite sides of the bottom of the can, the

'upper nut within the can being adapted to be engaged by a socket Wrench, and the packing washer arranged beneath one of said nuts.

2. The combination of a can'liaving at its bottom a surrounding rib, a spring device for said bottom of the can, and a protecting and supporting rim consisting of a band bent into circular form and having an offset portion to engage the rib upon the bottom of the can, one end of said band being formed with longitudinal series of openings, flexible tongues projecting from the other end of said band and adapted to be passed through said openings and'bent to adjustably secure the rim or bandupon the can, and supporting lugs projecting upwardly from the inner portion of the rim or band and engaged with the bottom of the can. In testimony whereof I hereunto affix my signature in the presence of two witnesses.'
