OIL CAN.

Application filed May 13, 1925. Serial No. 29,855.

To all whom it may] concern.

Be it known that I, JOHN J. Rrr'rnn, a citizen of the United States, residing at Ur bana, in the county of Champaign and State of Ohio, have invented certain new and useful Improvements in Oil Cans, of which the following is a specification.

My invention relates to improvements in oil cans, it particularly relating to an oil can of the kind which has an automatically closing valve to prevent leakage of the oil from the can.

An object of my invention is to provide a valve of the character referred to which may be readily installed in a conventional form of oil can without the necessity of any changes in the construction of the can.

A, further object of the invention is to provide a valve of this character which will be simple in construction and effective in its operation.

In the accompanying drawings:

Fig. 1 is a view partly in side elevation and partly in vertical section of an oil can showing my improved valve applied thereto.

Fig. 2 is a view of one side of the valve and its seat.

Fig. 3 is a view of the opposite side of the valve seat.

Referring to the drawings, 1 represents the body of an oil can of conventional form providedv'ith the usual exteriorly threaded neck 1' the upper end of which has an inturned ani'iular flange 1 to form a seat. A. domc shapcd cap 2 has an interiorly threaded portion 3 which screws in the usual way upon the neck of the can; the lower end of a spout 1: being suitably secured to the walls of a central opening in the dome-shaped portion of the. cap. A gasket 8 of leather or other suitable material is placed in the cap and cooperates with the seat 1 to provide for a tight joint; this gasket being usually -la1.uped between the seat and a shoulder 2 formed between the dome-shaped portion '2 and the threaded part 3 of the cap.

There is provided a disk 5 of sheet metal having an opening 6, preferably centrallyarranged. and also having secured thereto a strip 7 of spring metal. This strip 7 issecured to a disk near the outer edgethereof by rivets 7 or other suitable fastening fdevices and the inner free end overlies the opening 6.. The disk and its valve are inserted bet-ween the shoulder 2 and the gasket 8 with the spring strip 7 on the outer side of the disk.

In operation the natural resiliency of the strip 7 causes it to normally closely hug the face of the disk and close the opening 6. hen the bottom of the can is flexed in the usual way to eject oil the pressure in the body of the can caused by the flexing forces the valve 7 from its seat upon the disk and permits oil to flow from the body of the can to the spout l. When the cap and its spout are removed for filling purposes, the gasket retains the disk 5 in the cap so that no inconvenience is caused by the removing and replacement of the cap; the frictional engagement of the gasket with the threads of the cap serving to hold the gasket in place.

By the use of such a device, the leakage of the oil from the can is prevented, which adapts a can of this kind particularly to automobile use, as the can may be readily carried in the tool box without the danger of leakage. Further, by the arrangement described, the valve and its disk may be readily inserted in the conventional form of oil can shown without any change whatever in the construction of the can and may therefore not only be supplied in connection With new cans but also used to equip old cans if desired with an effective anti-leak device.

Having thus described my invention, I claim:

1. In an oil can, a body portion having a threaded neck provided with an internal annular flange at its outer end, a cap having a spout and provided with a circumferential flange, said flange having a plain upper cylindrical portion and a lower threaded portion to engage the neck, and an insertable member having a check valve located in the said upper cylindrical portion of said flange.

2. In an oil can, a body portion having a threaded neck provided with an internal annular flange at its outer end, a cap having a spout and provided with a circumferential flange having screw threads to engage said neck, an inserta-ble disk having a check valve located in the upper portion of said circumferential flange, and a gasket also located in said circumferential flange serving to hold said check valve member in position when said cap is removed.

In testimony whereof, I have hereunto set my hand this 8th day of May 1925.

JOHN J. BITTER.
