JOSEPH W. CUSHMAN, OF NEW YORK, N. Y.

OIL-CAN.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed October 30, 1905. Serial No. 285,219.

To all whom it may concern:

Be it known that I, JOSEPH W. CUsHMAN, citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Oil- Cans, of which the following is a specification.

My invention relates to oil cans and particularly to that class in which a valve is used which is automatically closed by a spring.

The object of my invention is to provide an oil can of this character, allthe parts of which may be made from sheet metal by stamping or drawing in order to manufacture at a low cost, and to produce a can of this type from which all the oil may be ejected, and also to provide a valve of large diameter to prevent leakage. This last feature is particularly desirable in cans of very small diameters, used for oiling bicycles, sewing machines, etc., in which the parts are made as small as possible so that the can as a whole can be conveniently carriedin the pocket if desired. 1

The drawings which form part of this application are about three times as large as the smallest cans I desire to make so it will be seen that the parts must be accurately made and assembled. The cans may-be made as large or much larger than the present drawings without changing the construction or method of making.

Referring to the drawings, Figure 1 is a central sectional view of the working parts of my improved can, with the cover or cap thereon. Fig. 2 is an exterior view of theupper end of my can, illustrating its general a pearance. Fig. 3 is an enlarged view of tile spout. Fig. 4 is an enlarged view of the valve washer and valve disk, which are alike in form. Fig. 5 is sectional illustrational view of a part of a bayonet joint. Fig. 6 is an enlarged view of'the shell J and washers.

A indicates the casing of the reservoir which is drawn from thin sheet metal and B indicates the top thereof which is provided with a thread B which is rolled or pressed or otherwise formed therein. 0 indicates the cap which is attached to the top B by a bayonet joint B which is formed by pressing the metal outward in the top to form a small cylindrical projection as illustrated. This projection is engaged by the horizontal depression formed in the interior of the cap C as illustrated at C (see Fig. 5) after it has through the expanded vertical part 0 entered said horizontal portion by passing The extreme upper end of the top B is provided with flange B which forms a seating for the gasket E and makes a tight joint between said flange and the stopper D.

The stopper D is provided with a thread D which engages with the thread B in the top B, and its outer edge is turned downward at D thus forming an annular groove D thereby covering the gasket E from view and providing at the same time, a surface for the fingers when removing the stopper and this surface may be corrugated to insure against the fingers slipping in case the stopper is tight in the top.

Fitted in the stopper D is a cylinder F, having its bottom end closed when drawn. This bottom is perforated by two holes, F and F respectively and by a central perforation F through which the spout Gmay pass freely and act as a guide for said spout. The

spout G is formed of sheet metal by first stamping it out in a blank, cutting out a portion of the metal at the bottom to form the projections G and G and then forming the sheet into the form illustrated. The valve disk H (see Fig. 4) is stamped from leather or other suitable material and is provided with two crescent shaped openings H and H and the washer I is formed exactly the same but is made of brass or other suitable metal. These crescent shaped openings H and H in the valve and washer engage with the pro.- jections G! and G2 of the spout G which are projected through them and their ends turned outwardly from the center, thereby holding said valve and valve washer firmly on the end of the spout as shown.

The upper end of the cylinder F is turned over to provide a smooth flange and strengthens the construction' Fastened to the s out G by a soldered joint J is a cylindrica shell J which'is closed in at the bottom end and the shell extended to form a bearing surface so that the solder will make a firm joint. The diameter of the shell J is such that it will slide freely within the cylinder F and its top end is expanded to form a flange J against which the fingers may rest in operatin the can and also acts as a drip cup for over ow of oil.

Surrounding the joint J is a metal washer K which is used to insure the edge of a companionleather Washer making a bearing a ainstthe wall of the cylinder F to prevent oi from escaping between the cylinder F and shell J, and M is a metal washer against which the spring N presses and thereby holds the said washers closely together.

The spring N abuts against the bottom of the cylinder F as shown and thereby holds the valve H tightly to its seat.

The operation is as follows :-To fill, remove the stopper D and pour in the oil. Replace the stopper tightly in position. Insert the can and press on the flanged top J 2 with the fingers, thus compressing the spring N and opening the valve H. The oil will How out through the opening G, and due to the shell J descending and thereby contracting the space below said shell, the air pressure within the can willbe correspondingly i11- creased and the oil in consequence thereof will be forcibly ejected from the can. By releasing the pressure on the flange J the spring N will react, and the valve close.

By the arrangement of the valve on the lower end oi'the cylinder 1*, and arranging the end of the stopper D to come flush with the end of said cylinder F, I am able to utilize the. ends of both for the valve to seat against and thereby use a much larger diameter of valve, which in the small size of cans is a decided advantage.

It willbe observed by the foregoing description, that I am able to make all the parts by stamping or drawing sheet metal and at the same time produce a much. better and.

stronger article than heretofore, and that all of the objects set forth are attained in this improved construction.

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

1. An improved article of manufacture comprising an oil easing, a stopper having a portion removably engaged with said casing, a cylinder also engaged by said portion and bearing in the stopper and having its lower end flush with the lower end of said stopper, a valve seated against said ends of the stopper and cylinder, and means for operating said valve, the construction being such that there are no internal surfaces in the upper part of the oil casing proper, occupying a higher plane than the valve seating.

2. An improved article of mamifacture comprising an oil casing, a stopper having a portion removably engaged with said easing. a cylinder also engaged by said portion and bearing in the stopper and having its lower end llush with the lower end of said stopper, a valve seated against said cylinder end, and means for operating said valve, all of the parts of sheet metal and the construction being such that there are no internal surfaces in the upper part of the oil easing proper, oeeupying a higher plane than the valve seating.

An oil can comprising an oil easing, a stopper having a portion removably engaged with said casing, a cylinder also engaged by said portion and bearing in the stopper and having its lower end flush with the lower end of the stopper, a valve seated against the lower end of said cylinder, and vertically movable valve operating means extending within the cylinder. t

4. An improved article of mamifacture comprising an. oil casing, a stopper removably secured to said casing, a cylinder hearing in said stopper and having its lower end flush with the lower end of the stopper, a valve seated against the lower end of the cylinder, a sheet metal spout, and a shell having a lower contracted end in l aring engagement with the spout to insure a lirm joint therewith 5. In an oil can, a sheet metal spout, a shell, having an upper oil-holding end, the lower end of the shell being ('(mtraeted and extended in bearing engagement with the spout, a cylinder forming with said shell an annular recess, packing material in said recess, said shell being vertically mo 'able with respect to the cylinder, and means fol iolding said packing material in position.
