H. HILL BUNGHOLE CLOSURE Sent.

HARRISON HILL, OF BURR OAK, KANSAS.
BUNGI-IOLE GLOSURE.
Application filed September 10, 1923. Serial 110.661,802.
T0 all lwhom it may concern.'
Be it known that I, HARRISON HILL, a citizen of the United States, residing at Burr Oak, in the county of Jewell and State of Kansas, have invented certain new and useful Improvements in Bunghole Closures, of which the following is a specification.
My invention relates to improvements in bung-hole closures for tanks and other containers, in which gasoline, oil or other liquids may be stored.
The object of the invention is to provide a novel bung-hole closure with an air vent which may be sealed, so that liquid cannot be drawn from the container through the' regular discharge valve, due to the air-lock existing in said'cont-ainer.
In order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:
Fig. 1 is a side elevation of a storage tank equipped with the closure.
Fig. 2 is an enlarged broken plan view of the container with the closure in position thereon.
Fig. 3 is a detail inverted plan view of the closure. l
Fig. 4 is a broken cross section on line IV--IV of Fig. 2, with the air vent of the closure in open position.
Fig. 5 is a broken cross section on the plane of line IV-IV of Fig. 2, with the air vent of the closure sealed. v
Referring now in detail to the various parts, A. designates a container provided at its upper portion with a bung-hole B and at one end with a valve C through which liquid may be drawn from the container when the air vent in the closure is opened.
2 designates the bung-hole closure which comprises a plug 4, a cap 6, a bolt 8, and a keeper 10. The plug 4 is exterior-ly threaded to engage the internal threads of the bung-hole B and has a hexagonal or other angular flange 12 for engagement by a wrench or other suitable tool whereby the plug 4 may be screwed in or out of the bunghole B. The plug 4 has an eccentric vent 14 through which the bolt 8 freely extends as shown by Figs. 4 and 5. l
The cap 6 is interiorly threaded to engage the threads of the bolt 8 and has a downturned marginal flange 16 and a centrallydisposed angular portion 18, whereby it may be engaged by a wrench or other tool to (screw the cap 6 up or down on the bolt 8.
The bolt 8 after being passed through the plug 4 and the cap 6 is crowned at its upper end 2() to coact with the keeper 10, fixed to the lower end of the bolt 8, in preventing removal of the plug 4 and the cap 6.
The keeper 10 is of such length as to permit it to pass through the bung-hole B and has an extension 22 at one end and aset screw 24 at its opposite end provided with a lock nut 26 for securing it at any point of its adjustment.
In practice the keeper 10 is adjusted relativelyV to the plug 4 as shownby Fig. 4, so
that it may pass through the bungehole rB F and permit the plug 4to be screwed into said bung-liole until the flange 12 engages the adjacent wall of the container A. The cap 6 with the bolt 8 is then rotated a half revolution to positionthe set screw 24 to one side of the plug '4, Fig. 5. rIhe cap 6 and the bolt 8 are then raised until the set screw 24 contacts the inner surface of the container A, after which the cap 6 is screwed down upon the bolt 8 and into engagement with the top of the plug 4, thereby sealing the vent 14 so that liquid'cannot be drawn olf through'the valve C. When the,cap 6 is being screwed down upon the bolt 8, as
stated, the latter is prevented from turning.
by the keeper 10, which abuts one side of a stop 28 on the underside of the plug 4. The keeper 10 and the stop 28 also prevent the' bolt 8 from turning while the cap 6 is being unscrewed. The cap 6 is then secured by suitable means such as a padlock E, the hasp F of which is passed through a transverse hole 30 in the bolt 8. The downturnedy flange 16 of the cap 6 preventsaccess to the rectangular portion 12 of the plug 4, so that the same cannot be removed from the bunghole B without first removing the padlock .E In some instances suflicientl leeway is left between the hasp F of the padlock E and the top of the angular portion 18 of the cap 6 to permit the latter to be unscrewed n a partial turn to uncover the vent 14so that liquid may be drawn off through the valve C without removing the padlock E.
From the foregoing description it will be understood that I have provided a device embodying the features above pointed out, and while I haveshown and described the preferred construction, combination and arrangement of parts, I reserve the right to make such changes as properly fall within the spirit and scope of the appended claims..r
Having thus described my invention, what l claim and desire to secure by Letters Patent, is;
l. In a device of the character described, a plug adapted to be screwed into the bunghole of a. container and provided wit-h an eccentrically located vent, a bolt extending through said vent, a keeper fixed to the lower end of said bolt and adapted to pass through the bung-hole when the bolt is turned in one direction and project to one side of the circumference of the bung-hole when the bolt is turned in an opposite direction, a member carried by the keeper andy adapted to engage the inner surface of the container when the bolt is turned in the lastH mentioned direction, and an element threaded on the bolt to seal the vent and hold said member in engagement with the inner surface of the container.
2. In a device of the character described, a plug adapted to be screwed into t-he bunghole of a container and provided with an eccentrically located vent, a bolt extending through said vent, a keeper fixed to the lower end of said bolt and adapted to pass through the bung-hole when the bolt is turned in one direction and, project to one side of the circumference of the bung-hole when the bolt is turned in an opposite direction, a member carried by the keeper and adapted to engage the inner surface of the container when the bolt is turned in the lastmentioned direction, and a cap threaded on the boltto hold said member in engagement with the inner surface of the container and provided with a marginal downturned flange to cover the upper margin of the plug.
3. In a device of the character described, a plug adapted to be screwed into the bunghole of a container and provided with an eccentrically located vent, a bolt extending through said vent, a keeper fixed to the lower end of said bolt and adapted to pass through the bung-hole when the bolt is turned in one direction and project to one side of the circumference of the bung-hole when the bolt is turned in an opposite direction, a. member carried by the keeper and adapted to engage the inner surface of the container when the bolt is turned in the lastmentioned direction, a cap threaded en the bolt to hold said member in engagemenr with the inner surface of the container and provided with a marginal. downturned flange to cover the upper margin of the plug, and means on the lower portion of the plug to prevent the keeper and the bolt from turning while the cap is being screwed upon or unscrewed from the bolt.
e. ln a device of the character described7 a plug adapted to be screwed into the bung hole of a container and provided with an eccentrically located vent, a bolt extending through said vent, a keeper fixed to the lower end of said bolt and adapted. to pass through the bung-hole when `the bolt is turned in one direction and project to one side of the circumference of the bung-hole when the bolt is turned in an oppositel direction, a member carried by the keeper and adapted to engage the inner surface of the container when the bolt is turned in the lastmentioned direction, a cap threaded on the bolt to hold said member in engagement, with the inner surface of the container. and means removably engaging the bolt above said cap to prevent the same from being unscrewed.
in testimony whereof I affix my signature, in the presence of two witnesses.
HARRISON HILL.
