a corporation oi' Ohio Application May 25, 1934, Serial No.' 727,512 9 Claims. (Cl. 220-86) This invention relates to improvements in closures for spouts,v tubes or pipes, and has for its object to provide ya closure that cannot be manipulated by an unauthorized person or by a l person who has not the implements by which the closure may be opened or closed. It is particularly the object of this invention to provide a closure for Vpipes used in connection with the sale of gasoline, and has for its object l` to provide a closure for such -a pipe that cannot be removed except by the person who is to ref-lll or supply gasoline to the tank.

It is an object of this invention to provide, in connection with a gasoline tank inlet pipe, means l for closing the end of the pipe, and a protector for the closing means which provides a 'trap for water so that `it may be absorbed by the-soil and removed from the pipe closure.

These and other advantages vwill appear from l0 the following description taken in connection with the drawings.

Referring to the drawings:

Figure 1 is a vertical section through the upper end of the tank pipe and the closure therefor 85 embedded in concrete shown in section.

Figure 2 is a view similar to Figure 1 but 'with the lid open and the spout closure removed.

Figure 3 is a top plan view of the lid for covering the upper end of the pipe and its closure.

l0 Figure 4 is a section on the line 4-4 of Figure l.

Figure 5 is ure 1. Y

Figure 6 is a section showing a part of the tank, the pipe connected thereto. and a gauge rod for determining the quantity of gasoline within the tank.

Figure 7 is a viewshowing the gauge rod with the markings thereon.

Figure 8 shows a key for removing the cap on the end of the spout or pipe. Figure 9 is a section on the line 9--9 of Figure 1.

The present cap structure is adapted to be used in connection with various `forms of pipes and spouts for closing them, but is shown in use in connection With a gasoline tank, which is indicated by the numeral I, and has thereon extending upwardly a pipe 2. These two members are embedded in the ground, which has over it a bed of concretey 3, provided with an opening'or hole or pit to receive a casing 4 having lateral iianges 5 that rest in a seat provided therefor in the upper surface of the layer oi concrete (Figure 6).

The upper end of the casing, which in the a section on the line 5 5 of Figpresent instance is cylindrical, has a seat 6 for receiving and seating a lid I pivoted at one side by means of a pivot 8 (Figure 1). On the side of the lid opposite the pivot is a latch member 9, in the form of a bar, connected at one end to a 6 stem I0 which extends through the 11d and is operated by means of a suitable key member I2. The other end oi' the latch is adapted to it in a slot II formed in the inner surface oi the casing. This slot is so formed that by moving the 10 latch in one direction it will engage the casing wall in the slot and be stopped by the material of' the casing at one end of the slot.

On the upper end of the pipe or spout a ring I3 is threaded by means of threads on onel end 15 of the ring. On the interior ofthis ring is a pair of oppositely disposed U-shaped ribs Il, which provide seats I5 for `receiving a key, such as shown in Figure 8, for rotating the ring to thread it on the upper end of the pipe or thread l0 it off the pipe. 'This ring has intermediate its ends pins or projections I6 which extend outwardly from the ring and project into a groove I9 formed in a sleeve I1, loosely fitting over the ring and the upper end of the pipe. The ring, in 5 fact, forms the upper removable end of the pipe and for all purposes may be considered a part of the pipe. Y

The lower end of the sleeve is bent inwardly to form a flange I8, which closely fits around the 30 outer surface of the pipe 2. beneath the ring I3. The upward movement of the sleeve may be limited both by the flange I8 and by the pins I6 engaging the surface of the sleeve at the lower edge of the groove I9. 'I'he sleeve and the ring 55 may be formed oi. cast iron. The pins preferably are made of some non-corrosive material, such as Monel metal. The upper end of the pipe is closed by means oi a cap 20, preferably made oi brass, and provided with peripheral flanges 2| 40 adapted to be threaded onto the other end oi the ring.

On one side of the cap is a perforated lug 22, while on the sleeve there is a perforated lug 23. The perforations or holes in these lugs are indi- 5 cated by the numeral 24. These holes, by properly positioning the cap and the sleeve, may be in alignment and when so aligned a lock member 25 is adapted to pass through the holes 24 to hold the cap and the sleeve against rotation 50 one with respect to the other.

On the central part of the cap is a boss 2B, which has extending through it and the cap a hole 21. For closing this hole there is provided a winged inner threaded plug 28, preferably 55 Y lid'l and lthe top of the casing 4. The bottom of this space has therein sand 1To Vthe lower end of this made of brass or semeV other suitable material. To the lower end of this plug one end of a4 short chain 29 is attached by means of a cotter pin 30. Y chainis attached oneV end of a gauge rod 3|,Vwhich has on its other or lower end a pin 32 to-prevent the gauge rod from being removed from the tank so long as the cap is in position on the spout. Y, l On the upper surface of the cap is a pair of oppositely disposed U-shaped projections 33 which provide seats 34 for receiving a key member, such as shown in Figure-8. This key pipe Yor placing the ring upon the pipe. The upperend of the pipe and the Yclosure instrumentalities therefor do not entirely fill the cylindrical casing l but leave an annular-space 35 (Figure 6)V which servesto trap or catch any water that might pass between the 35YY so that thewater trapped therein may easily escape. By this means the upper end of the spout or pipe is protected from water. i

The graduations 31 on the rod 3| (Figure 7) are for the Vpurpose of indicating the amount of Y liquid, such as gasoline, within the tank. The cap is provided with a'gasket 38 adapted to engage the upper surface of the ring to form -a close airtight and gas-proof connection so'that thergasoline within the tank may not vapor'ze and escape.

Y' The cap Vopposite the lug 22 is provided with a K ately above the groove lug 39 adapted to engage a iiange 40 on the upper end of Vthe sleeve I1. YThis flange forms with the adjacent parts of the sleeve a groove `4| immedi- IS, in which ,the pins i8' Work. The key 42 for moving both the ring and the cap is the same, and is shown in Figure 8.

" The key 42 for operating these members is in the possession of the'man in charge of the delivery trucktank. No other person is supposed to have onejof these keys. By this means the boot-legging of gasoline is prevented. No gasoline I can be supplied to the'tank' I except by the personv in charge of the key. VIf the cap be threaded off of theV upper end ofthe pipe or spout it cannot be entirely removed therefrom because of the engagement ofthe pins with the sleeve and because of the lugs 22 and 23 being locked togethenand because of Vtheengagement of the lug 39 with the flange 4E; When the lock, which is intended'to hold the'perforated lugs 22 and 2l together, is

removed the capmay be rotated by aninstrument such'as that shown in Figure V8. This rotation will ultimately remove the'cap from the upper end ofthe tube or spout, and thecap'can then e be removed from the sleeve l1 by raisingl the lug side thereofV so that the'part 3l cyanlpa'ss by the V `the hole inthe cap provided for the plug 28 bej I cause, in the first place, this hole is'small; Vjust large enough for the chain 29 and thegaugerod l 8l topass-through. it,'and secondfbecause these membersV can-notbe removed from the cap,'and

either the chain, the gauge rod or theplug is always in the hole provided for the plug so it Vwould jrbe'impossible to supply any gasoline'to the tank Y"les" through-this hole except in a'very small'quantity,

which would be wasteful.

While'the upper end of the pipe and the closure instrumentalities therefor are shown beneath the upper surface of the groundor concreteY flooring thereon. the pipe'may project abovethe ground member is for the purpose'of rotating the cap withrela V tion to the tube andring, and is also usedfor re- Vmoving theV ring from the Vor other porous soil onto said pipe.

and the same closure instrumentalities be applied thereto. As shown in the drawings, no obstruction is presented to top of the spout or any part of ture. i Y
