Application December 9, 1982. Serial No. 646,527

6 Claims. (01. 2202l) The present invention relates to a closure for tanks, containers and the like, and has for one of its objects the provision of a closure of the character indicated, preferably consisting of but three main parts to constitute an article of manufacture of rigid, sturdy construction.

Another aim of the invention is to provide a device such as specified, having a base preferably provided with means for attachment to the neck of a tank or the like, which base also functions to hingedly and swivelly support the cap or lid of the closure.

Still a further purpose of the invention is to construct a closure cap which is not only hingedly and swivelly supported on the base, but in addition is capable of being securely locked thereto.

Yet another object is to provide a structurally integral base for a closure cap, swivelly and hingedly supported thereon and, in addition, to provide means for positioning a rubber gasket in the base for making a seal with the cap, as well as supplying means for securing the base to the neck of a tank, automobile radiator and the like.

A further desideratum of the invention is the construction of a closure of the type specified, in which the hinge between the base and closure cap is materially relieved of all strain and pressure therebetween in locked condition.

The above and other objects and purposes will be apparent from the more detailed description hereinafter appearing, when taken together with the drawings forming a part hereof and to which reference is now specifically made, and in which Fig. l is a side elevational view of the neck of a tank, such as the radiator of an automobile, showing my improved closure operatively positioned thereon with its cap in closed or locked condition, as well as the cap in open position, as indicated by the dotted lines;'

Fig. 2 is a sectional view taken on line 22 of Fig. 1, showing the manner in which the locking lugs of the cap and base cooperate to lock the former to the latter;

Fig. 3 is a plan view of my improved closure showing the cap or lid in open or unlocked position with respect to the base;

Fig. 4 is a sectional view taken on line 44 of Fig. 2, illustrating the manner in which the cap cooperates with a gasket positioned on the base to form a seal for preventing the escape of the contents of the tank or radiator to which the closure is secured;

Fig. 5 is a sectional view taken on line 5--5 of Fig. 2, and, in addition to the showing of Fig. 4, illustrates the cooperation of the cap and base to lock these parts toeach other;

Fig. 6 is a view on line 66 of Fig. 4, showing how a ring is secured to the closure and how it serves to lock the latter to the spout of a radiator, tank or the like;

Fig. '7 is a sectional View of my device with the cover removed, showing a modified manner of securing my closure to a spout;

Fig. 8 is a top plan view of the structure of Referring first to Fig. 1 there is illustrated the neck or spout S of a radiator of an automobile showing my improved closure, generally designated as C positioned thereon. While for purposes of illustration my closure is shown as mounted on the neck or spout of an automobile radiator, it is desired to emphasize thatit is equally adapted for use as a'closure for a gasoline tank or in fact any opening or aperture of a container or receptacle. The character B represents the base of my improved closure C on which is hingedly and swivelly mounted a closure cap or lid L shown in Fig. 1 in both open and locked position on the base.

Said base B is preferably formed of a collar, of circular outline, having a pair ofadjacent shoulders or seats 9 and 10 for a purpose to be later described. arranged in stepped relationship, that is, seat 9 is below the general level of the collar and seat 10 somewhat lower than 9. Projecting towards the interior of the base, away from the seat 10,

It will be noted that the seats are within a central opening, are a pair of ears 11--11'. Each of these has a threaded aperture 12l2', respectively, for the reception of screws 13. The latter extend through threaded holes 14-15 in a spout locking ring 16, best seen in Fig. 6, the ring having integrally cast therewith a pair of lockinglugs 17'l8 which extend diametrically from the circumference of the ring and serve to hold a washer 17 In assembling this portion of the device, the screws 13 are inserted within the threaded apertures of the ears, the washer 13 put in place, and the screws then fed through the holes in the spout locking ring until the latter rests firmly against the bottom surface of the ears. In attaching the base of the closure on a spout S of a radiator, the lugs 1'718 are inserted through oppositely arranged slots 19 cut in a flange 20 extending inwardly from the spout edge. It will now be seen that by giving the base B of the closure a half turn, the lugs will be secure the base thereto, and that the washer 1'1 will form a seal between the closure base and the spout. swivelly mounted within the base on the seat 9 thereof, is a hinge ring or plate 21 provided with an elongated segmental cutout portion 22 at its edge, as well as with two similar spaced but smaller slots 22 and 22 Protruding inwardly from the base to extend over the seat 10 and ring 21 are a plurality of spaced tongues or projections 23, 23 and 23 It will now be seen that in order to mount the hinge ring 21 on the seat 9 it is but necessary to bring the slots 22, 22 and 22 into registration with the tongues or projections 23, 23 and 23 and by then rotating the hinge ring to break the registration, said ring will be maintained in position on the seat, In order to removably hold the ring in place, a small stop screw or the like 24 is screwed into the seat, the head of the screw also overhanging the ring. The arrangement of the parts just described is such that the extent of movement of the ring is regulated by the stop screw 24 which contacts the edges of the ring defining the slot 22, the two extreme positions being shown in Figs. 2 and 3. It will be observed that in neither of these positions are the tongues 23, 23 and 23 in registration with the slots of the ring, thereby precluding removal thereof, Without unscrewing the stop member 24.

Hingedly secured to ring 21 is a closure cap or lid Ldhaving an interior rim 25 cast integrally therewith and extending therefrom for cooperation in locked condition of the lid on the base with a rubber gasket 26 resting on the seat 10, whereby toeffectively seal the contents of the radiator R therewithin. The lid is also provided with a pair of inwardly protruding locking projections or lips 27 for cooperating with a pair of spaced cam locking ribs 28 formed on the base 13. The manner of locking the lid to the base will now be obvious. The lid is moved about its hinge towards the base, the parts being in the position shown in Fig. 3. After the lid has contacted the base, the former is rotated, which causes the ring 21 to move from the position shown in Fig. 3 to the position of Fig. 2, so that the lips 27 engage the cam locking ribs 28 to tightly draw the rim 25 into contact with the gasket 26 to firmly seal the radiator contents therewithin and simultaneously lock the lid to the base. In this position the hinge between the base and lid is materially relieved of much strain and pressure. To open the lid it is of course merely necessary to rotate it in an opposite direction from that described to thus disengage parts 27 and 28 and permitting swinging the lid about its hinge to open position. In lieu of the locking ring 16 for securing my novel closure to a spout or a tank or the like, the base B may be interiorly threaded as shown at 30 in Fig. '7 for threading engagement with a corresponding thread on the spout S. In this instance the ears 11, the screws 13 and the locking ring 16 are unnecessary.

From the above description it will be seen that there has been provided a novel closure of simple construction, few parts, yet well adapted to perform the functions specified. Also it will be obvious that various modifications may be made in the specific construction shown without departing from the spirit of the invention, and it is my intention to cover all such modifications a base, said base having its upper face provided with a seat and a locking lug at its edge, a hinge ring, cooperating means carried by the ring and base for swivelly positioning the ring on the seat, stop means for limiting the swivelling movement of the ring, a cap hingedly connected to the ring, and means carried by the cap for engagement with the lug of the base to lock the cap thereto when the ring is moved to one of its extreme positions against the stop.

2. A closure for tanks and the like comprising a base, said base provided with a pair of spaced, stepped seats positioned therewithin, a hinge ring mounted on one of said seats and a gasket within the other, means for swivelly mounting said ring, a stop carried by the base for determining the extent of movementof the ring, a cap hingedly connected to the ring, locking lugs carried by the base and cap, an interior rim Within the cap, said ring and lugs cooperating to lock the cap on the basewith the rim in contact with said gasket.

3. A closure for tanks and the like comprising a base having its upper face recessed to provide an annularly extending seat, a member arranged for movement within the seat in a plane substantially parallel thereto, means upstanding from the upper face of the base and cooperating with the member for holding it in position on its seat, said member having a cap hingedly secured thereto.

4. A closure for tanks and the like comprising a base having its upper face recessed to provide an annularly extending seat, a lug upstanding from the base and having a portion overhanging the seat, a member arranged to rest within the seat for movement in a plane substantially parallel theretoand beneath the overhanging portion of the lug, said lug arranged to hold the member in position on the seat, and the member having a cap hinged thereto.

5. A closure for tanks and the like comprising a base having its upperface recessed to provide an annularly extending seat, a lug upstanding from the base and having a portion overhanging the seat, a member arranged to rest within the seat for movement in a plane substantially parallel thereto and beneath the overhanging portion of the lug, the latter arranged to hold the member in position on the seat, said memher having a cap hinged thereto, and a second lug cooperatingwith the cap to lock the same to the base upon movement of the member on its seat.

6. A closure for-tanks and the like comprising a base having its upper face recessed to provide a pair of concentrically arranged seats, a member mounted for movement within one of the seats in a plane substantially parallel thereto, means for holding the member in position on its seat, a gasket within the other seat, a cap hinged to the member, means for locking the cap to the base, said cap having means for pressing upon the gasketwhen locked to the base.
