OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 664,669, dated December 25, 1900.

Application iiled April 9,1900. Serial No. 12,161. (No model.)

To all whom Lt may concern:

Be it known that I, CAEL NOEDHAUGEN, a citizen of the United States, residing at Aneta, in the county of Nelson, State of North Dakota, have invented certain new and useful Improvements in Oil-Cans, of which the following is a description, reference being had to the accompanying drawings and to the letters of reference marked thereon.

1o My invention relates to improvements in oil-cans, and more particularly to that class of such devices in which the oil is forced therefrom.

My objects are to provide a means for regulating the amount of oil fed at each operation of the parts, to permit the outlet port or ports to be closed and the parts locked in this position, and to provide a structure of can which can be readily filled and in which the plunzo ger and its attached parts can be quickly and conveniently withdrawn for cleaning, repair, dac.

To these ends and also to improve generally upon devices of the nature indicated my 2 5 invention consists in the various matters hereinafter described and claimed.

In the accompanying drawings, Figure l is a central sectional elevation of the present can, the sprin g and plunger-rod, however, be-

ing shown in side elevation; and Fig. 2 is a bottom plan view, this viewshowing the plu nger-cap in the position it occupies when the parts are locked in position to close the outlet-ports.

Referring now more particularly to the drawings, A represents the can-body, having the spout a and provided with a depressed or cone-shaped bottom at. extends longitudinally through the can-body,

4o the upper end of the same forming the spout a, while its lower end extends through the can-bottom. Near the upper end of the canbody this tube is provided in its walls with ports a2, through which the contents of the can proper can pass into the tube, to be expelled therefrom by means of a plunger operating in the tube, said tube thus forming a chamber to receive oil from the can proper, said chamber also communicating with the 5o spout. The plunger comprises a head b, a rod b', attached thereto, and a cap b2, to which A central tube A' the said rod is also connected. Said cap projects beyond the tube end and is normally held in this extended position by means of a spring C, which bears against the cap and a suitable portion of the tube. When the cap is in this normal position, the plunger-head rests below the ports r2-. e., at the side of the ports opposite the spout-ready to expel from the can-spout the oil which has been 6o drawn into the tube from the can-body when the plunger moved into the position indicated. Manifestly the amount of oil drawn into the tube and expelled therefrom by the action of the plunger is determined by the distance below the ports a2 to which the plunger-head moves when returning to normal position, and in order to regulate this I provide means for adjusting the distance between the plungerhead and the cap, the normal position of the 7o cap being rendered constant by the spring C. This adjustment is accomplished by reason of the threaded rod end, which enters a correspondingly threaded seat in the cap. The plunger-head of course fits snugly within the tube, so that by rotating the cap this is screwed one way or the other along the plunger-rod, thus, in effect, varying the length of the plunger, and consequently adjusting the normal position of the plunger-head with relation 8o to the ports, the cap being, as previously explained, normally held in a constant position and its amount of inward movement being limited by its laterally-extending flange b3 contacting with the can-bottom. By reason of the construction just explained the operator can set his Vplunger to deliver a large or small quantity of oil at each operation. The ange b3 is eccentric with relation to the cap, whereby it presents, in effect, a projection upon one 9o 'side of said cap, and a lug or catch ais suitably provided upon the can -bottom. The plunger parts are so proportioned that when the cap is forced inwardly to bring the flangek between the said lug and the end of the tube A the plunger-head lies across and covers the ports a2. When, therefore, the parts are brought into this position and the cap turned to bring the wider portion of the flange above the said lug-t'. e., between the lug and the Ioo tube end-said lug lies in the path of movement of the iiange, and thus locks the head in position, closing the ports a2 and preventing accidental discharge from the can. The can can then be safely carried in a tool-bag. When it is desired to operate the can, the cap is turned to carry the wider liange portion out of contact with the lug, and the plunger can then be readily reciprocated.

It will be noticed that the bottom portion of the tube A' is of greater diameter than is its body portion, whereby there is produced the inwardly-extending shoulder a4. This shoulder forms a seat for the inner end of the spring C, (which spring is preferably spiral and encircles the plunger-rod,) while the outer spring end is attached to the cap, as by means of an ear a5, upon said cap bent over upon the spring. Thus' the plunger and spring are only frictionally held within the tube and can be readily withdrawn for cleaning, repair, e. Further1nore,when the plunger is thus withdrawn and the can inverted, with the air-vent a6 open, said can can be filled by simply pouring the oil upon the bottom, the inclined walls of which cause it to act as a funnel. By closing the air-vent and reinserting the plunger the can is again ready for operation.

The present can is simple in its construction and its parts can be readily assembled. The discharge of oil can be regulated, the parts locked in position to close the outletports, the can can be easily and quickly filled, and the plunger and its spring readily withdrawn for cleaning or repair. The device is a cheap and efficient oiler.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In an oil-can or the like, a plunger adapted to expel the oil in its movement, said plunger comprising a plunger-head, an exterior cap under the control of the operator, and connection between said cap and head, said connection including means whereby the distance between the said cap and head can be adjusted; substantially as described.
