OIL-CAN ATTACHMENT,

Specification of Letters Patent.

ratenteaoet. 14,1913.

Application filed March 21, 1912. Serial No. 685,255.

To all whom t may concern Be it known that T, LOUIS H. BURCI-m'ri, a citizen of the United States, residing at Cashion, in the county of Kingfisher' and State of Oklahoma, have invented certain new and useful Improvements in Oil-Can Attachments; and T do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved attachment for oil cans.

One object of the invention is to provide an oil regulating feed attachment which may be applied to any can already manufactured without any change being made in the structure of the can.

Another object is to provide such an attachment which may be used equally well with an oil can which has lost the spring in its bottom.

Another object is to provide a feeding attachment for oil cans adapted to extend through and project at one end beyond the free end of the can spout to provide for the use of said feeder end as a cleaner for the oil holes of machinery, and when the oil is forced out of the can it will run down said projecting feeding end and the operator can readily see when the oil is flowing properly.

Another object is to provide an oil feeder having adjustable regulating means to permit more or less oil to flow as may be de- Sii-ed and which is especially useful in warm weather when the oil is thin and flows freely.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings: Figure 1 represents a vertical sectional view of a can equipped with this improved attachment, parts of the attachment being broken out; Fig. 2 is a similar view showing the can in inverted position, such as is assumed when in use; Fig. 3 is a side elevation of another form of the invention; Fig. A is a vertical section thereof.

In the embodiment illustrated in Figs. 1 and 2, a can l is shown provided with a bottom 2 of resilient metal which may be forced inward for actuating the feed device hereinafter described, said bottom readily expanding and assuming its normal position after actuation in the manner ordinary in cans of this character. This spring bottom while desirable is not necessary for use in connection with this attachment as said attachment may be equally well em ployed in connection with cans the bottoms of which have lost their spring.

A spout 3 of ordinary construction is threaded in the usual manner at its lower end in an interiorly threadedneck of the can 1.

This improved valve or feeding attachment comprises a stem 5 preferably conipcsed of two members 6 and 7 adjustably connected and extensible to vary the length of the stem 5 as sho-wn. These members comprise atubular lower member 6 threaded interiorly and exteriorly and in which is mounted an upper smaller member 7 which is threaded for the greater portion of its length and adapted tc be screwed into the member 6, the free outer end of said member 7 being preferably reduced and provided with smooth faces on which may be stamped any desired inscription. Mounted on the threaded portion of the member 7 is an inverted cone shaped valve 8 having a threaded bore extending therethrough to provide for its adjustment on the member 7 and which is adap-ted to lit in the outer end of the can spout and provide a suitable closure therefor, and which may be adjusted at any desired point on said member 7 to regulate the quantity of oil permitted to iiow from said spout in a manner to be described.

A nut 9 is mounted on the lower member 6 of the stem 5 and is adjustable thereon to vary the tension of a coil spring 10 which is mounted on said member 6 between said nut 9 and the inner end of the can spout. Nhen it is desired to increase the tension of the spring 10, the nut 9 is screwed up on the member 6 whereby the valve member 8 will also be held normally in closed position fitting tightly within the mouth of the spout prior to the depression of the can bottom by the operato-r. A cushion 11 is secured to the lower end of the member 6 and is adapted to bear on the bottom of the can, forming a receiving socket or seat for said stem member 6. This cushion 11 is preferably composed of felt or any other similar material and is designed to prevent wear on the can bottom such as would occur during the operation of the valve, or feeding attaehment.

The stem member 7 is preferably provided with a plurality of longitudinally spaced oil cups 12 which'are adapted to hold t-he oil and when the 'stem is lmoved forwardly forces the oil out through the can spout which is especially desirable in cold weather when the oil is thick.y

In the operation of the device when a small quantity of oil is. desired toy be fed from the can spout the cone shaped valve member 8 is moved inwardly on the member 7 and when more oil.` is required it is moved outwardly. This valve 8 is so positioned on the ste-m 5 thatJK it always remains within the spout of; the can .and thereby holds the feeder always in the center of the can bottom. Nhen the oil is. pumped up' by pressure exerted on thebottorn of the can the cups 12 catchA theoil and force it out.

through the spout.

By arranging the spr-ing on the stem 5 i between the nut 9 and the inner end of the spout of the can, said spring when so positioned operates in the same manner as a re* silient can bottom and thus adapts the device to be used equally well with a can which has lost the spring in its bottom.

In Figs. 3 and 4; the regulation feed attachment is` shown especially designed for use in cans having crooked or curved spouts, such as are employed by railway engines and thev like. This device is constructed similarly to that shown in Figs. 1 and 2, except that the curved spout 8 is provided with a tubular arm 13 extending at an acute angle preferably from a point near its inner end and communicating with the interior of the can spout to provide for the insertion of a curved stem or plunger 14. This plunger' projects at opposite ends beyond the outer end of the spout 8 and the free end of the arm 13 respectively. The end of the "plunger which projects beyond the spout end is threaded and provided with an inverted cone-shaped valve 8 similar to valve 8 and is designed to normally provide a tight closure for the mount of the can spout. A coiled spring 15 is mounted on the other end of the plunger 14 between the free end j of the arm 13 and the nut 16 on said plunger end, which latter is threaded to receive the nut which is designed to adjust the tension of said spring. A push button 16 is secured to the end of the plunger which projects through the arm 13 and is adapted to be vpressed by the thumb of the operator for forcing the plunger forward against the tension of the spring 15 to offset the valve 8" and permita predetermined quantity of oil to iiowk out through the spout, the quantity being controlled by the adjustment of the.

valve 8 on the outer end of the plunger.

I claim as my invention: An oil feeding attachment for cans comprising a sectional stem the sections of which arey connected for longitudinal adjustment, one of said sections having screw threads near its outer end, said end' beyond said threads being reduced and provided with smooth faces, an inverted cone shaped valve adjust-ably mounted on the threaded portion of said stem section, a nuty mounted on the free end of the other section and adjustable thereon7 and a coiled spring mounted on said last mentioned section and adapted to bear at one end on said nut by means.

of which the tension thereof is varied,fand a cushioning element secured tov the terminal of said stem section.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
