Letters Patent No. 94,564, dated Septmnbe'r 7 1869 antedated August 27, 1869.

IMPROVEMENT VIIN' 'OIL-CAN.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern.-

Be it known that I, CHARLES Onruuoox, of Brooklyn, in the county of Kings, and State of New York, have invented a new and useful Improvement in Oil- Cans; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of 'this specification, in which is represented a Vertical section of an oil-can, constructed according to my improvement.

This invention relates to the construction of cans for oiling machinery, whereby a stream of oil may be thrown forcibly and with such precision that joints not easily accessible may be oiled with little or no waste of oil.

It consists, first, in a chamber in the upperpart of the reservoir of the can', provided with an outlet through the nozzle above, and communicating with the reservoir by means of'a tube below, which extends upward into the said chamber to a point near, the top thereof, and terminates below into adlexible tube of suicient length and degree of ilexibility to extend to any part of the reservoir.

1t consists, secondly, in a valve situated in the cap of `the illing-nozzleV and so constructed as toopen inwardly, and by means of which air is admitted into the reservoir to fill the vacuum caused by the consumption ofthe oil and by the springing 'out of the bottom ofthe can after it has been relieved from' the Iexternal pressure by which itis pressed inward when oiling.

In order that others may be better enabled 'to understand the construction and operation of my irnproverhent, I will proceed to describe' it, with reference to the drawings.

v A is achambe'rin the upper part of the reservoir E, which terminates above into the nozzle a.

B is a tube, passing through and screwed into the lower extremity of the chamber A, extending above the centre of the chamber upward and reachingdown- .ward below the bottom of' the chamber A, asuicient -distance to attach thereto a` tube, B', of leather or other suitable flexible material', of suicient length and degree of ilexibility to reach any part of'the reservoir E. Y

F is an outer shell or jacket encasing the nozzletube a, not only for the pnrposeot" protecting the same from injury, but, by its lower extremity being attachedto the base ofthe nozzle a, aspace or chamber, O, is formed, which receives the waste oil which runs down upon the outside of the nozzle after being used, and retains -the saine for further use upon such parts of the machinery as may be lubricated by inverting the can, 'thereby eecting a saving of oil which would otherwise be wasted.

D is'the cap, which closes the illing-nozzle, into which is inserted a valve, e, constructed so as to open inward, and through which air is admitted to tillthe vacuum occasioned by the consumption of the oil, and

yby the springing out ofthe bottom of the can after external pressure has been removed. A

The operation of my invention is elected in the usual'way by compression of the bottom of the can,

whichy forces the oil up through the tube B into the chamber A, and out at the nozzle a, leaving the chamber A, after such operation, full of oil to the level of the tube B, and is there'retained for oiling such joints or journals as are easy of access, and which may be lubricated by inverting the can, `in which instance compression of the bottom isnotnecessary, 'as the chamber A is of a capacity to vcontain such a'quantity of oil as is geueralysnicient for this purpose, and hence will supplyto the journal or joint a desirable quantity, and no more, thus obviating the objection to an ordinary oil-can, in which there lis no-means of regulating the quantity of oil discharged ata time, air being supplied to the cham ber A, whenthe can is inverted, through the tubes B 'B-', by the rarefactionor expansion of the air contained in the can su'iciently to allow the oil to flow therefrom. V'

, What is here claimed, and desired to be secured by Letters Patent, is*- 1. The chamber A, arranged in combination with the tubes B B', nozzle a, and reservoir E,`ot an oilcan, substantially as herein shown and described.`

2. The combination of the Ivalve e with the reservoir E, tube B B', and chamber A,` substantially as and for the purpose specified.
