Application filed July 19,
i all whom it may concern:
Be it known. that l, Anvnno G. Vi iciiivnn, a citizen of the United States of America and resident. of Winner, in the county of Tripp and State of flouth Dakota, have invented certain new and useful Improvements in Caps for Fuel Tanks of Automobiles, of which the following is a specification.
This invention relates to caps for closures for tanks and particularly for tanks employed as containers for gasolene in automobiles, the said cap having novel means whereby a valve is held in coactive relation to a valve seat in an air nipple conimunieating with the interior of the tank and the air externally thereof.
An object of this invention is to produce a cap having; an apertured nipple with a valve seat therein, the said nipple beingexternally threaded at its outer end to form a connection with an air pump, whereby air may be forced to the interior of the tank for exerting pressure on the contents of the tank in effecting a feeding action, the said nipple being also provided with a cover effective to guard the air passage to prevent the entrance of foreign substances and integral lugs forming a valve cage to prevent the valve from becoming disassociated from the seat with which it is to coach lt-is a further object of this invention to produce a cap or cover of the character in cheated which can he produced inexpznsively since the material is struck up or dis torted to form the retaining elements by which the valve is confined.
It is wellknown that in certain types of automobiles depending upon gravity teed, the feeding action is retarded or wholly interrupted if the automobile is ascending a steep grade, and in such instances, it is desirable to force the fuel to a carburetor. By the use of a device embodying the invention an air pump may be connected to the nipple and air can be forced into the tank to such an extent as to develop pressure to accomplish, the result and upon the removal of the pipe con-, nection, the air within the tank will serve to force the valve to its seat and retainthe pressure within the tank. 1 1
With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and ing parts stances.

combination of parts to be hereinafter more i'iully set forth and claimed.
in describing the invention in detail, reference will be had to the-accompanying; drawings forming part of this specification, wherein like characters denote correspondin the several views. and in which' i i I Figure 1 illustrates a view in elevation of a threaded cap embodying the invention;

In these drawings 5 denotes a cap which is externally threaded as shown at 6 to fit a, threaded aperture of a tank.
A nipple 7 formed integral with or at tached to the cap has a hollow portion 8 forming a valve cage in which a valve 9 operates. The nipple has a passage 10 leading to its outer end, and the said nipple is externally threaded as shown at 11 to form a connection for a coupling ofan air pump, in order that the hose or connection may be attached to the nipple when air is to be delivered to a tank. A cover 12 is threaded on the outer end of the nipple when the pump connection is removed and thisserves to prevent the entrance of In the construction of the cap 'or cover, 4L 1 V the valve 9 is placed in tne cage and thereafter the under surface ofthe cap or the inner end of the nipple is distorted to form the lugs 13 which are caused to project under the valve and so restrict the opening as to prevent the dislodgnient of the valve from the cage.
In the construction of the lugs, I have found that the lugs or retaining points tor the valve may be formed with a four conered tool driven against the outer surface of the cap or nipple near the wall of the valve cage, an action which results in d torting the metal to a degree which will result in the production of the valve securing' means. I I i The body may be provided with a flange 14, although the construction of this part of the cap is an immaterial detail.
The valve 9 coacts with a valve seat 15 formed in the said nipple.
