THOMAS E. BURNING, OF NEWARK, NEW JERSEY.
Specification of Letters Patent.
Patented Sept. 18, 191 '7.
Application filed March 10, 1917. Serial No. 153,839.
To all whom it may concern:
Be it known that I, THOMAS F. DURNING, a citizen of the United States, residing at Newark, in the county of Essex .and State of New Jersey, have invented certain new and useful Improvements in Oil-Can Vents, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to improvements in oil can vents, being especially adapted for use in connection with oil cans for holding lubricating and other oil, it being the present practice to provide no vent for these cans so that in pouring the liquid it has been found necessary to puncture the top and thus render the can useless for a second or subsequent filling.
It is therefore the object of this invention to provide a vent which will be securely held in place against accidental removal but which can be readily removed when the liquid is being poured, thus permitting the can to be refilled as many times as necessary and not necessitating the .loss of the can after the first filling.
In the accompanying drawings:
Figure 1 is a perspective view of an oil can.
Fig. 2 is a diagonal'cross section through the top thereof.
Fig. 3 is an enlarged detail View of the vent closure.
Referring to the drawings, the numeral 5 designates the can proper which may be of any conventional shape, here shown as a rectangular body, the top being provided with the filling or pouring outlet 6. The vent opening 7 is formed by pressing the material of the top inwardly to provide the lips 13 so that the closure 8 may be seated firmly therein against accidental displacement.
This closure 8 is provided with a flexible connection 9 by means of which the same is attached to the can to prevent its accidental loss.
The disk 10 thereof forms the outer closure to prevent the liquid from oozing out when the vent is closed while the resilient holding member 11 is composed of a single piece of metal having a plurality of tangs 1.2 from the body and carried by the disk 10, the same exerting an outward pressure so when in position as shown in Fig. 2, the gasket 14 will be held tight upon the outer surface of the top of the can and the vent opening 7 closed.
From the foregoing description it is evident that with a vent device of this kind for oil cans, the can will have renewed life inasmuch as it will not be destroyed by producing a vent opening as is the usual custom and that with the closure the vent opening will be closed tightly so that the oil will not leak out at this point.
What I claim as new is:
1. A sheet metal receptacle having a vent opening formed in the top thereof, the wall of said opening being tubular and convexed cross sectional longitudinally thereof, and a closure for the opening flexibly connected to the receptacle, said closure including a circular sealing member, and a resilient member of lesser length than the wall of the opening for engaging the wall to frictionally hold the sealing member in close contact with the outer face of the receptacle adjacent the opening.
2. A sheet metal receptacle having a vent opening formed in the top thereof, the wall of said opening being tubular and converted cross sectional longitudinally thereof, a closure for the opening flexibly connected to the receptacle, said closure including a circular sealing member, a resilient semiglobular wall engaging member carried by the sealing member of the closure and of such length as to project slightly below the narrowest point of the opening, whereby the sealing member is held in close contact with the outer face of the receptacle, and a gasket interposed between the sealing member and the semi-globular wall engaging member for engaging the outer face of the receptacle.
In testimony whereof I affix my signature.
THOMAS F. BURNING.
