Renewed July 7,/"1938 (o1. V22o-33,) flange, as illustrated in Figure 1 of the drawing 'of this character` associated with a cap perma- `nently secured to the tank neck and includinga plurality of pivoted., closure segments slidable l horizontally .across the top of the cap and secured to thei'cap in a manner to prevent removal therefrom.

' Other objects and` advantages reside in the details of construction and operation as more'fully hereinafter described and claimed, reference being 'had .tothe accompanying drawing forming part'hereof, wherein `.like numerals refer to like f parts throughout andin which: k

'showingFK the segments in closed position.

kFigure 4 is a similar view showing the segments in openposition, and

Figure 5 is a sectional view taken substantially 'E on 'a' line 5-5 of Figure 2.

Referring now to the drawing in detail, in which rfor the purpose of illustration I have disclosed a preferred embodiment of my invention,

the numeral 5 designates a tank having a filling 'k neck 6 Lextending upwardly therefrom, the upper v4I.)

edge of the neck bent inwardly and downwardly to provide a flange 1 for engagement by laterally projecting lugs 8 formed on a perforated theftvproof device, forming the subject matter of a co- 'pending application, and which embodies a perforated cylindrical member indicatedl generally atj9 yhaving a flange I0 at its upper openend y .-.resting upon the top of the tank s. A surnamek 'gasket I I is interposed between the flange and the neck to prevent rattling of the parts. The peripheral edge of the flange is stepped, as shown atk I2 upon which is seated the down-turned flanged edge I3 of a closure'cap I4, the latter be- .ing secured to the flange I Il by one or more screws YIsls `AI5 which are inserted upwardly through the to prevent unauthorized removal of the cap.

'Ihe construction of the downturned flange i3 spaces the cap `|4 from the flange to provide a working chamber-indicated at I6, for a pair oi 'and 2|, positioned on topv of the cap are also secured to the respective plates by rivets or the like 22. Spacing blocks 23 are interposed between thefplates yI1 and the segments 2B and 2I to prevent binding of the sameagainst the upper and lowerA surfaces of the cap.

As will be understood from an inspection oi Figure 5 of the drawing, the segments 20 and 2l cooperate to form a vclosure for the opening I3 ofl the cap. K

The segments '20*and 2I aregpreferably in the form of half a disc having their straight edges in abutting engagement and the lsegment ZI is formed with a rib 22 which overlies the adjacent edge of the segment 20 to cover the abutting edges of the same when in closed position.-

A wire spring member 23 is provided for yieldably'maintaining the segments in closed position, said spring member having its respective ends inserted in recesses 2l formed in the plates I1, the intermediate portion of the spring having one or more convolutions 25 formed therein through which the screw I5 is inserted to secure the spring to the cap I 4. As clearly illustrated in Figures 3 and 4 of the drawing, the ends of the spring extend from its associated recess 24 transversely of the plates I1 in a manner to yieldably urge the plates toward each other in a closed position. Theplate I1 which is secured to the closure segment 20 is provided at its inner edge with a notch 26 and the other of said plates, which is secured to the segment 2| is provided witha headed extension 21 seated in said notch and engages the sides of the notch to simultaneously open the segment 20 when pressure is .exerted upon the rib 22 for the purpose of openf ing the segment 2|.

For this purpose the outer edge of the rib 22 is provided with a curved notch 28 adapted for engagement by the nozzle of a filling hose whereby lateral pressure against the rib will spring the segment 2| and the segment 20 into an open position to permit insertion of the nozzle in the opening I8 for filling `the tank.

It is believed the operation and advantage of the device will be readily understood from the foregoing without further detail explanation.

What we claim is:-

l. A tank closure comprising a cap secured to the filler neck of a tank, said cap having an opening communicating with the neck, a pair of closure segments mounted for swinging movement into and out of position over said opening, a pair of plates pivotally connected to the under side of the cap and xedly secured to the respective segments, said segments and plates 'being larger than the opening to prevent removal therethrough, interengaging means between the plates for the simultaneous actuationV A thereof, and spring means yieldably urging the plates and'segments to a closed position,4 Y' l. v

2. A tank closure comprising a cap secured to the ller neck of a tank, said cap having an opening communicating with the neck, a pair of closure segments mounted for swinging movement into and out of position over saidopening, a pair of plates pivotally connected tothe underside of the cap and xedly secured to the respective segments, said segments and plates being larger than the opening to prevent removal therethrough, interengaging means between Athe plates for the simultaneous actuation thereof, spring means yieldably urging the plates and segments to a closed position, and vmeans carried by one of the segments for swingably actuating the same upon application of pressure upon said means in a direction corresponding to the swinging movement of said one segment. l l

3. A tank closure comprising a cap secured to the lter neck of a tank, said cap having an opening communicating with theneck, a pair of closure segments mounted for swinging movement into and out of position over said opening, a pair of plates pivotally connected to the under side of the cap and xedly secured to the lrespective segments, said segments and plates being larger than the opening to prevent removal therethrough, interengaging means between the plates for the simultaneous actuation thereof, spring .means yieldably urging the plates and segments to a closed position, and a rib carried by one of Vthe segments overlying the adjacent edge of the other segment, said rib having a notch along one edge engageable by a filling nozzle for swingably actuating said segments.

4. A tank closure comprising a cap secured to the ller neck of a tank, said cap having an opening communicating with the neck, closure means comprising a pair of disc-like segments, having their edges in abutting relation and cooperating to cover said opening, a pair of plates pivotally connected to the under side of the capand iixedlyl secured to the respective segments, said segments and plates being larger than the opening to prevent removal therethrough, a notchl in one of the plates, a headed extension on the other plate engaged in the notch and cooperating to actuate the plates and segments simultaneously, andk spring means yieldably urging the plates and segments to a closed position. Y

5. A tank closure comprising a cap secured to the filler neck of a tank, said cap having an opening communicating with the neck, closure means comprising a pair of disc-like segments having their edges in abutting relation and cooperating to cover said opening, a pair of plates pivotally connected to the under side of the cap and iixedly secured to the respectivel segments, said segments and plates being larger than the opening to prevent removal therethrough, va notch in one of the-plates, a headed extension onV the other plate engaged in the notch and cooperating to actuate the plates and segments simultaneously, spring means yieldably urging the plates and segments to a closed position, and a rib carried by one of the segments overlying the adjacent edge of the other segment, said rib having a notch along one edge engageable by a filling nozzle for svvingably actuating said segments.
