IMPROVEMENT IN VENTILATING DECANTING APPARATUS FQR OIL-CANPS.

Specifica-tion forming part of Letters Patent No. 117,984, dated August 15, 1871.

To all whom t may concern:

-Be it known that I, WILLIAM CLEVELAND, of Orange, in the county of Essex and Stat-e of New Jersey, have invented a new and Improved Self- Ventilating Can, of which the following is a specification:

My invention is designed to obviate the disturbance and spilling of liquids, which occurs when they are discharged from air-tight cans and other air-tight vessels which have only a single orice for the discharge of the liquid and for the entrance of the air necessary to cause it to iiow, occasioned by the entrance of the air and discharge of the liquid through the same aperture. This I eii'ect in a more convenient and substantial way than has hitherto been done, by a ventilating-tube for the admission of air to the upper surface of the liquid in the can, within the can itself, thus affording it the protection of the cover by striking up7 a groove in said cover and soldering a strip beneath the same so as to prevent the liquid from obtaining access to the groove. This strip may be made long enough to bend up into the discharge-tube, so that the lower side of the ventilating-tube shall be all in one piece.

Figure lis plan ofthe top of my ilnproved can, showin g the spout for the discharge of the liquid and the tube for admission of air. Fig. 2 is a vertical section on the line a' a', Fig. l. Fig. 3 is a vertical section on the line y y, Fig. l.

The vessel or can may be constructed of sheet metal or any other suitable material, and has an oriiice or spout, A, at the top, through which it is filled, and by means of which the contained liquid is poured out. A tube, B, for the admission of air to the surface of the liquid extends from a point, U, within the said spout and along it and the top of the can to a point near the op posite side, where there is an orifice, D, communicating' with the interior, or that part in which the liquid is contained.

When it is desired to empty the can this is effected by inclining it so that the liquid will run through the spout A, while at the same time the external air enters the orifice C and passes through the Ventilating-tube B to the surface of the liquid through the orifice D, avoiding any interfere-nce between the outgoing liquid and the entering air, and causing an equable and uniform discharge through the spout A.

rllhis arrangement possesses the advantages of strength, neatness, and ease of application in manufacture.

I do not claim constructing a can or other airtight vessel with separate orifices for the discharge of liquid and for the admission of air, having an outward opening in common, nor do I claim a tube for the admission of air when the same is located on the outside of such vessel and extends diagonally from the body of the can to the spout or discharge-orifice.

I claim- A can or vessel provided with a tube for the admission oi' air, formed by striking up a groove in the head or top of said vessel and eementin g thereto a strip to form the other side of said tube, which tube projects into the nozzle of the can at the side uppermost in decanting, substantially as and for the purpose set forth.

WILLIAM CLEVELAND.
