1 j character which will effectively prevent theft of the contents of the-tank or container and which may be easily and quickly applied to tank or container now in use without p alterations or special construction of the neck o. of the tank or container.

Another object of this invention is the provision of an effective securing means between the cap and the neck o-f the tank which will prevent unauthorized removalof the cap but which will permit convenient removal of said cap by employing a key orthe like so that the tank may be filled whenever desired. Y

A further object of this invention is the provision of means to establish a leak-proof connection between the cap and the neck of the tank with suitable vent means which will prevent the escape of the contents of thetank due to splashing thereof.

A still further object of this invention is the provision ofV a cap or closure for tanks or containers of the above stated character which will be simple, durable and efficient and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view, this invention consists in Certain novel features of construction, combination and arrangement of parts to-be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying dra-wings, in which Y Figure 1 is a sectional view illustrating a cap occupying a position locked to theneck of a tank and constructed in accordance with my invention.

Referring in detail to the drawings, the numeral l indicates a filling neck of a tank or container which has formed thereon retaining flanges 2 of arcuate shape in plan view as shown in Figure 3 and are transverse` ly curved as shown in Figuresjl and 2 to be.` engaged by retaining ngersof a closure cap.` The foregoing description relates to a well known type of neck for tanks or containers now in use and to which my invention may be easily and quicklyapplied without undue alterations.` l

` A. cap 3 of hollow formation has yformed thereon an annular neck or flange l to receive the neck -1 as shown in Figures 1 and 2 and the cap is preferably constructed from plates 5 and 6 with their edges secured together as shown at 7. The plate 6 is concave and provided with a marginal ange 8 while the plate 5 is convex and provided with a flange 9 bent about theliange 8 to rmly secure the plates together in cap formation.

The plate 5 is provided with a centrally located key opening 10 for receiving a key 11 employed to operate the securing means be-` tween the cap and the neck 1 and which will be hereinaftermore fully described.

7 is a plan view illustrating a clo- A journalled plate 12 is suitably secured to the inner face of the plate 5 of the cap 3 and has a centrally arranged opening positioned about the key opening 10 with a depending guide flange 13. A portion of the journal plate 12 is odset from the plate 5 of the cap 3 to form a bearing' seat 14 engaged by an annular flange 15 formed on the upper end of the supporting member 16. The supporting member 16 is of hollow formation having a cylindrical portion 17 and a hexagonal shaped portion 18. rlhe hexagonal shaped portion 18 provides angularly disposed faces 19 provided with slots 2() opening outwardly through the lower edge of the hexagonal shaped portion. The lower ends of the slots 2O are enlarged as shown in Figure 6 to form attaching lugs 21 received in angularly shaped slots 2 2 of a closure disk 23. The lugs when positioned within the slots 22 are headed or offset for the purpose of taching the closure disk to the supporting member 1,6 and it also will be noted that thc supporting member provides a rotat ableponnection between the closure disk and the cap 3.

vThe closure disk has struck out therefrom spaced guide posts 24 on which .is slidably mounted the latch memher 25 in the form of adisk 26 having oppositely disposed arms 27 formed integral therewith. .the arms 27 are bent downwardly and outwardly7 from the disk 26 to provide finger portions 28 that are transversely curved to provide upper concave bearing portions 29 adapted to engage under the flanges 2 of the neck 1,.

pin or rod 30 is secured centrally to the closuredisk and projects above and below the latter and has its lower end extended through a centrally arranged aperture 31 in the latch member 21 and has its lower end headed as shown at 32. The headed end of the rod 3,1 supports a washer 33 forming a seat for a coiled spring 34 that bears against the'latching member and which urges the latching member toward the closure disk for the purpose of bringing the fingers 28 of the arms 27 in tight engagement with the flanges 2` of the, neck 1. Having the convex faces l29 of the fingers 28 provides a construction which will permit the lingers to adjust themselves to the edges of the flanges 2 and adapted to compensate for wear between these parts during the use of the device.

A gasket 35 is secured to the closure disk 23 and seats against the edge of the neck 1 as shown in Figures 1 and 2 for the purpose of establishing a leak-proof connection between the closure disk and the neck. A vent disk 36 is slidably mounted upon the Supporting member 16 and is held in tight engagement with the closure disk by the action of a coiled spring 37 mounted on the upfper portion of the pin or rod 30. The vent disk 36 is of substantially the same size as the closure disk and is provided with an annulargroove 38 provided with a vent opening 39 for the purpose of placing the interior' of the tank or container under atmospheric' pressure when the cap is applied to the neck. It is to be understood that the vent disk 36 is slidably mounted on the supporting member 16 and moves with the closure disk 23.

A hexagonal shaped operating plate 40 has formed upon its outer edge upstanding marginal flanges 41 and is centrally cut away to form `a bearing plate 42 connected to the major portion of the operating plate by radially extending arms 43. vThe cut-out portion of the plate 40 provides a plurality of openings 44 with the outer walls of said openings of angular shape cooperating with each other in forming the inner edge of the major portion of thev operating plate of hexagonal shape. Angularly disposed flanges 45 are formed ont-he inner edge of the major portion of the operating plate and form bearing surfaces to slidably engage the angularly related faces 19 of the hexagonally shaped portion 18 of the supporting member 16 with the arms 43 extending through the slots 20 and with the rod or pin 30 extending through the bearing plate by way of the opening 46. The bearing plate 42 engages one end of the coiled spring 37 for normally supporting the operating plate in a position as shown in Figure 1.

A keeper plate 47 is secured to the inner face of the plate 6 of the cap 3 and has a comparatively large opening 48 therein through which extends the supporting member 1,6 and the walls of the opening 48 are cut away to provide angularly related faces 49 to receive the flanges 41 of the operating plate when the latter is moved downwardly as shown in Figure 2 by the key 11 so that by turning the key the operating plate will be rotated imparting rotation to the cap, supporting member 16, and latching member 25, disengaging the arms 27 thereof from the flanges 2 of the neck 1 thereby disconnecting the cap from the neck 1.

The key llpis adapted to fit between the arms 43 of the operating plate so that on turning the key the operating plate will move or rotate therewith. If desired, a suitable locking mechanism consisting of a key barrel may be mounted within the supporting member 16 and associated with the operating plate that on inserting a key in the key barrel, the locking plate may be depressed and rotated. It is to be understood that the key barrel and its mounting` within the supporting member forms no part of this present invention and therefore is not shown.

With the cap applied to the neck 1 as shown in Figure 1 it is impossible to remove said cap from the neck without the employment of the key 11 and will provide a very eli'ective closure for the neck permitting the neck of the tank to always be under atmospheric pressure .through the vent openings in the vent fdisk. TheV vent ndisk being so located that the splashing of the fluid within the tank and neck will .be prevented from Aescaping.
