fl 10 all wlw/m t may concern.' l

Be 1t known that l, JosnrH A. WARREN, a citizen of the United States, residing and State of New Hampshire, have invented certain new and useful Improvements 1n Tank-Closures; and l do declare the follow-i ing to be a full, clear7 and exact description of the inventioin such as will enable others skilled in the art to which it appertains to make and use the same.

T his invention relates broadly to improve ments in closures, and it has more particular reference to an improved closure especially, although not necessarily, designed 'for use in connection with automobile gasolene storage tanks.

(lne object of the invention is to provide a self-closing Yvalve t'or tanks or other containers in which volatile liquids such as gasolene are stored, the valve beinp automatically seated by spring pressure, and when opened and released, immediately returnable to its vnormal closed position to ei'ect an eX- tremely tight closure; the construction and arrangement oi' the closure being such as to permit it to yieldl and permit the escape of excessive gas from the tank7 thus sewing as 4a safety valve.

Another object oi the invention is to provide a closure which is composed of comparatively few simple and inexpensive parts which are so correlated that they insure effective results and permit easy and ready unseating of the valve when the 'tank is being; filled.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanyingr drawings finining.,r a part of this speciiication and in which like numerals arc employed to. designate like parts throughout the same: j

Figure l is an elevational view of a device constructed in accordance with my invention, the same being shown in the manner in Awhich it is associated with the filling open in in a gasolene tank.

1ig. 2 is a sectional view thereof which more clearly discloses the construction and arrangement. l I f Fig. 3 is a View similar to Fig. 2 showlng the valve in open position to permit the tank to be filled.

Figs. 4 and 5v are sections taken'on the lines-4 4A and .55 respectively of F 1g; 2.

at l Manchester, in the county of Hillsborough' By referring to the drawings,y it willibe seen that the numeral l designates a tank provided with a filling lopening 2 which under ordinary circumstances is closed by means of a screw-cap. It is my intention to do awaywith this screw-cap land substitute my novel automatically spring-closed valve device. This device .comprises a closure 3 includingr a channel portion 4f to accommodate the insertion oi a yieldable packing.'- ring Il which engages the tank in the marin ner disclosed to insure a tight closing. In

addition to this channel portion, this valve A also includes a depending part 5 which. ex tends through the opening 2 and into the interior of the tank. Suitable air vents 6 will,I of course7 be provided. Disposed in the tank adjacent the opening 2 .isa substantially rectangular plate 7 which is provided. with a central opening registering with the opening 2, the portion ofthe plate surroundingy this opening being bent inwardly to provide an endless flange 8 which serves a purpose to be hereinafter described. This plate is provided with combined anchoring and anti-slipping means being preferably in the form of spurs 9 which are formed by simply bending the corners of the plate iaterallyto bring them' into engagement. with the tank. It is to be noted that'the plate re' ferred to is of such a' width that' it may be turned endwise and the device easily in-` serted through the hole in the tank. l

As before indicated, the valve 3 is selfclosingr 'and it is here shown asbeing closed by means ofa coiled spring l0 which surrounds the vflange 8 .at one o its ends and hears against the plate 7,. it being connected. with the valve through the medium of flexible connectors in the form of chains l1'- which are connected at their inner ends to a channel member 12 1n Which the inner end of said coiled s ring is seated.y With this mal position by means of the spring and' v E i ,eeeeee sure device are so simple fluit the voet oi manufacture of lle device is comparatively small. 4 l

These and oeher advantages and features of my invention, have no doubl7 become npparent from' J@he foregoing dcecripiion.

A careful consideration of ehe i'oregoing description taken in connection with lie scconlpallyinge,` drawings, thought ce be suffieient to enable persons skilled in art to' which this invention relates, to obtain a. clear underelanding'oi ehe seine and the manner in which it operates. For this ree son, a more lengthy description is deemed unnecessary.

Since' probably lie heet results may be lobcaned with the construction and arrangement hereinv flieclcsed und described this construction. and arrangement teire'nnxs the preferred embodiment of my niven'ion. However, I wish it to he understood that minor changes in @he shepkeyf-eize, and arran'genieniJ ci' parte muy be resored 'to with The parte cmout departing 'roin che spirit' of the inven- "tion or the scope of-the subjoned claim.

claim: l .y In combination a container provided with e lling'aopening, a Substantially conical valve closing and extending through said opening, a coiled spring for closing and retaining the valve closed, a channel-shaped ring in "the,- contniner receiving the inner end of said spring, said ring carrying opposed hooks, chains connecte-d to the valve :ind said hooks, and n substantially square flat plate of a size to permit; it to be inserted tl'nough the aforesaid filling opening', said plate constituting;f an abutment for the spring' and being.r disposed within the container and arranged between the upper end of the spring and the valve, being centrally aperjtured' to permit free passage of the Huid therethrough and also permitting passage of Athe pointed end oi the vali'e therethrough,

said opening being surrounded by u laterally downturned 'flange extending into the upper end of the spring to prevent lateral displacement of the latter,4ghe corners of the plate being beni, laterally up to provide spurs which engage the adjacent' wall of the con miner for retaining the plate in position,

said spring serving the additional function of insuring an eective engagement of the spurs with the container Wall. v

in testimonyT whereof here hereunto set my hand.
