E. E. DRUMM CLOSURE CAP Nov. 5, 1929.

Filed Oct. 10 1927 Patented Nov. 5, 1929 UNITED STATES PATENT OFFICE ELMER E. DRUMM, OF MANITOWOC, WISCONSIN, ASSIGNOR TO ALUMINUM GOODS MANUFACTURING 00., OF MANITOWOC, WISCONSIN, A CORPORATION OF NEW JER- SEY CLOSURE GAP Application filed October 10,

This invention relates to closure caps. Objects of this invention are to provide a closure cap such for example as a cap adapted for use on the gasoline tanks of automobiles, which is so constructed that it is impossible to have the gasoline splashed out through the vent opening in the cap, but which still provides a continuous vent for the tank.

Further objects are to provide a novel form of tank cap which is very easy to construct, in which the several parts may be most easily assembled, and which presents a very pleasing and attractive appearance.

An embodiment of the invention is shown in the accompanying drawings in which:

Figure 1 is a sectional view through the p;

Figure 2 is a plan view of the structure 20 shown in Figure 1.

Referring to the drawings, it will be seen that the cap comprises a substantially inverted cup-shaped member having a transverse upper portion 1 and approximately cylindrical side portions 2. These side portions may terminate in a beaded lower edge 3 in order to strengthen the lower edge and also to provide a finished appearance. If desired, the outer face 2 of the portion 2 may be knurled.

The upper portion is provided with a raised annular portion 4, and this annular portion is provided with one or more vent apertures 5. In the form shown, three have been illustrated as shown in Figure 2, although obviously the number of vent apertures may be varied, as desired. One alone may be used if required. Below the top portion 1, a metal washer 6 is positioned and held tightly in place against the underside of the top 1. This washer 2 extends across the raised portion 4.- and provides therewith an annular passageway or channel 7 The washer is provided with one or more vent .1 apertures 8 which are arranged in staggered relation to the vent apertures 5, as shown in Figure 2. The washer 6 is held in place by means of the transverse member 9 which is riveted or otherwise secured to the top 2, 1? and which is provided with depressed por- 1927. Serial No. 225,225.

tions 10 which receive the inner marginal portion of the washer 6. Preferably, the member 9 is a flat strap-like spring member and is provided with downwardly'and outwardly turned arms 11 adapted to engage and interlock with the throat or neck portion of the tank, such neck portion may, if desired, be provided with inwardly projecting lugs, or otherwise constructed to cooperate with the members 11 and thus lock the tank cap in place. a I

A cork, composition, or leather washer 12 is carried within the cap and is of annular contour, as shown in Figure 1. It is adapted to tightly engage the upper or outer end of the kfilling neck of the tank and thus seal the tan r I It is to be noted also that the member 9 can be fastened to the top 1 in other ways than by rivets in an obvious manner.

It will be seen that I a very simple and serviceable type of cap has been provided which may be readily applied, Which will close the mouth of the tank, and which yet provides for a limited venting of the tank.

It is to be noted particularly that the liquid or gasoline within the tank cannot splash outwardly due to the peculiar construction de scribed above. Suppose, for instance, that gasoline should by any chance pass through one of the apertures 8 into the space 7. It will not pass outwardly through any of the apertures 5 as these apertures are out of alignment with theapertures 8. In addition to this, the gasoline will run back into the tank through the apertures 8 and thus no gasoline will be lost.

It is to be noted further that the cap is of very attractive appearance and is highly serviceable in operation.

It is obvious that the top may be formed flat and the channel may be formed in the ring-like member 6, and that other changes maybe made without departingfrom the spirit of this invention. Therefore, although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim:

1. A cap comprising an integral metal 5 member having a transverse top portion and cylindrical side walls, said top portion having an annular inverted channel-shaped raised portion provided with a plurality of apertures, a washer positioned below said channel portion and closing the underside of said channel portion, said washer being provided with a plurality of apertures out of alignment with the first mentioned apertures.

2. A closure cap for a tank comprising a body portion having integral cylindrical side walls and having an upwardly struck channel-like portion of annular contour on its upper side, said upstruck portion having apertures therethrough, a washer positioned below said upstruck portion and having apertures therethrough out of alignment with said first mentioned apertures, and a transverse retaining member holding said washer in place.

5' 3. A closure cap for a tank comprising a body portion having integral cylindrical side walls and having an upwardly struck channel-like portion of annular contour on its upper side, said upstruck portion having aperao tures therethrough, a washer positioned be low said upstruck portion and having apertures therethrough out of alignment with said first mentioned apertures, and a transverse retaining member holding said washer in 36 place, said transverse retaining member having outwardly turned ends.

4:. A closure cap for a tank comprising a body portion havingcylindrical side wallsand having an annular upstruck channel-like portion formed in its body portion and provided with a vent opening, a washer positioned beneath said channel-like portion and having an aperture out of alignment with said first mentioned aperture, a transverse retaining member secured to said body portion and retaining said washer in place and having outturned lower arms, and a gasket carried within said body portion.

5. A closure cap including a body having an annular inverted constricted channelshaped raised portion formed in its top and provided with a plurality of apertures, and a removable closure plate for the open side of the channel member having a plurality of apertures therein arranged out of alignment with the apertures in the raised portion.

In testimony that I claim the foregoing I have hereunto set my hand at Manitowoc, in the county of Manitowoc and State of Wisconsin.
