OIL-CAN.

Specification of Letters Patent.

Patented Dec. 12, 19l6.

Application filed May 7, 1915. Serial No. 26,584.

a To all whom it may concern:

Be it known that we, OLE FAULsoN and Jason B. NELSON, citizens of the United States, residing at Rhame, in the county of Bowman and State of North Dakota, have invented new and useful Improvements in Oil-Cans, of which the following is a specification.

The invention relates to oil cans, and more particularly to the class of machine oilers.

The primary object of the invention is the provision of an oiler of this character wherein the parts thereof are readily and easily removed so that in event the said oiler fails to work the same can be conveniently repaired.

Another object of the invention is the provision of an oiler ofthis' character wherein the pump for forcing the oil through the spout can be removed so that the oil will freely flow through said spout, this being done should the pump become inoperative.

A further object of the invention is the provision of an oiler of-this character wherein the construction thereof is of novel form to assure the perfect working of the same.

A still further object of the invention is the provision of an oiler of this character which is simple in'construction, reliable and efficient in operation, and inexpensive in manufacture.

With these and other ojects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

ln the drawings :Figure 1. is a side elevation of an oiler constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 is a sectional view on the line 33 of Fig. 2. Fig. 4 is a St ctional view on the line 44lof Fig. 2.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the, drawings in detail, the oiler comprises a body 5 preferably made from metal, and is formed with an inwardly dished bottom 6 and an upwardly arched or semi-sphericalshaped top 7 while'without the body is a handle 8, the top 7 being formed with a central internally threaded being formed with passages 15 adapted to register with the passages 11 in the plug 10 so that oil from the body 5 will flow therethrough to the spout for lubricating machinery or the like.

Mounted centrally in the inner plug 10 is a feed tube 16 which extends within the body 5 for a portion of the length of the same. Formed in the dished bot-tom centrally thereof is an internally threaded nipple 17 in which is detachably engaged a screw cap or plug 18, the nipple 17 being formed with an inturned annular flange 19 at its inner end, and insertible through this nipple 17 is a piston barrel 20, one end of which is formed with an out-turned annular flange 21 to engage the flange 19 on the nipple 17, while its opposite end telescopes over the inner end of a hollow boss 22 which projects through the top 7 of the body 5 and carries at its outer end a threaded cap 23 through which works the stem 2% of a piston 25 which is reciprocatingly movable within the barrel 20, and against this piston works a coiled expansion spring 26 which is confined and held suitably seated within the said barrel 20, the spring being designed to automatically move the piston outwardly after being forced inwardly in the barrel,

.the outer end of the piston stem 24 being 28 and the flangedend 21 oft-he said barrel.

On actuating the piston 25 within the barrel the oil contained therein is under pressure for the feeding of the same to the feed tube 16 which has its inner end extended into the said barrel 20 for communication therewith.

The inner end of the barrel 20 is closed through the medium of a flexible disk 31 which'is seated upon the flange 2 1 and held fast by the plug 18 when engaged in the nipple 17 in the bottom 6 of the body of the oiler. In the use of the pump the oil will be forced under pressure from the body 5 through the spout l-l for lubricating inachinery or the like.

-The pump structure can be readily removed from the body 5 so that the oiler can be used in the ordinary well-known manner.

Detachably mounted in the top 7 of the body 5 is a cap 32 so that the said body can end of said tube 16, the valve being normally engaged in the seat when the oil can is at rest so as to close the feed tube from admitting atmospheric air to the can.

From the foregoing description, taken in connection with the accompaiu'mg draw-' ings, the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

\Vhat is claimed is 1. An oiler of the class described comprising a body having a hollow boss formed at its top and also having a dished bottom provided with a central internally threaded nipple, a barrel extended through the nippie in the bottom and engaged with the boss at the top of the body, an annular flange formed on th lower end of the barrel and received in the nipple on the bottom, aclosure plug tapped in the nipple in the bottom and engaging the flange on the barrel, a plunger working in the barrel, :1 spring seated within the barrel and acting upon the plunger, a two-part plug, one partbeing vided with a central internally detachably mounted in the top of the body centrally thereof, a collar detachably connecting the two parts of the plug, a discharge spout carried by one part of the plug and a valved feed tube leading from the barrel to the two-part plug, said two-part plug being formed with passages for establishing communication between the body and the said spout.

2. An oiler of the class described comprising a body having a hollow boss formed at its top and also having a dished bottom prothreaded nipple, a barrel extended through the nipple in the bottom and engaged with the boss at the top of the body, an annular flange formed on the lower end of the barrel and received in the nipple on the bottom, a closure plug tapped in the nipple in the bottom and engaging the flange on the barrel, a plunger working in the barrel, a spring seated within the barrel and acting upon the plunger, a two-part plug, one part being detachably mounted in the top of the body centrally thereof, a collar detachably connecting the two parts of the plug, a discharge spout carried by one part of the plug, a valved feed tube leading from the barrel to the two-part plug, said two-part plug being formed with passages for establishing communication between the body and the said spout, a downwardly tapered valve seat formed in the barrel near the lower end thereof, said barrel being formed with a plurality of apertures below said valve seat,

and a valve normally engaged in said seat.

In testimony whereof we afiix our signatures in presence of two witnesses.
