DRAINING VALVE FOR DRUM RECEPTACLES Original Filed May 5, 1942 Patented Nov. 7, 1944 UNITED, STATES PATENT OFFICE DRAINING VALVE FOR DRUM RECEPTAOLES Alpha orHolveck, Victoria, lexr r Continuation of application Serial No. 441,837,

May 5, 11942.

This invention relates generally to'the class oi 1 receptacles, and dispensing means therefor, and pertains particularly -to receptacles designed;- to contain fluid or semi-fluid substances from which such substances are] withdrawn, either under the action of gravityor byuse'of a pressure means, through a dispensing nozzle.

In certain types of receptacles suchyforexample, as drums and cans used for lubricating oils or oils of other types and also other fluids,

the dispensing opening is usually located in one head of the receptacle, thus making it necessary that the receptacle be tipped over or mounted on its side upon a suitable rack in; order'that the contents may be withdrawn.

The present invention has for its principal character stated wherein such drawofimeans includes a rotatable portion which, when turned in one direction, opens the draw-off meansan'd when turned in another direction. closes .the same, the said rotatable portion being designed to have a dispensing hose or nozzle eoupl edtherewith. v 5 f Still another object-of the-invention is to pro- .vide a draw-off means of the character stated This application December 2, 1943,Serial N0. 512,6

.' lo-rain (or. 222-189) v transporting oils and 'otherfluid, showing-the present invention applied thereto.

Figure 2 'is' a view in elevation of the drum attached portion of the invention.

--Figure 3 isa horizontal sectional view taken on-the line 3--3 of Figure 1. v

Figure 4 is'a vertical section taken on the line 4- --4 of Figure 2. Referring now more particularly to the draw ing, the numeral'l generally'designates a metallic barrel or drum -in association with which the present invention is shown but itis to be under stood that the use of the invention is not to be confined to receptacles of this type butIthat the invention may be used upon any fluid containing receptacle where such use isfound feasible.

In applying the invention to an already constructed receptacle or drum such asis illustrated, the 'wall of the drum is cut away at one en'd'to form an opening 2 bordered by the. vertical wall portions, or edges 3and the top and bottom edges a novel draw-off means for receptacles of the -4 and 5, respectively. Into'this opening 2 there isset a closure member in the form of a plate indicated generally by'the numeral 6 which is pressed or otherwise suitably formed to provide the wall 1 which is of rectangular form, and it conforms to the outline of the opening2, and has the right angularly' extending top, bottom and side bordering walls 8, 9 and I0, respectively, which merge at their free edges with the con-5 tinuous encircling and laterally directed flange which is mounted upon the receptaclein a novel a 1 manner whereby thereceptacle may be rolled'o'r otherwise handled without, danger of damaging the draw-ofi means. V Still another object of the invention is to pro vide a novel construction which-is adapted for 1 ready application for standard types of drums and receptacles, or which may be built into the receptacle when the same is 'cons tructed.'

The invention'will be best understood from a consideration of the fcllowing detaileddescription taken in connection with the accompanying drawing, it being understood, however, that the invention isnot'to be considered as limited by the specific illustration or description butjthat' such illustration and description constitute a preferred embodimentof the invention.

In the drawing: p Figure 1 is a view in side elevation of a drum or barrel of the type commonly 'employedior 'H. The .wall Iv is spaced asubstantial distance from'the plane of the flange ll, thus providing theletter I p The plate 6 closes'the' opening 2 and thewall portion! and theborderin'g walls integral therewith enterthe'opening 2, as is shown in Figures 3 and 4, while th efiange II is positioned against the outerface of the drum-and iswelded or other wise suitably secured thereto to form a fluid tight joint therewith.

- The central portion of'the plate wall I is proa chamber or "vestibule which is designated by vided with an opening I2 and upon the inner side I of the wall I is secured a reinforcing centrally apertured'plate l3 and this plate has the central aperture thereof screw threaded and the thread is continued through the opening l2 of the wall;

a The threaded opening of the plate 13 is indicated by the numeral l4 and this has threaded therethrough the exteriorly threaded sleeve l5 which is of constant diameter from its outer end to the integral collar or flange I6 which is carried upon. its inner end' upon the inner side of the plate [3. r w

Encircling the sleeve I5 is a gasket H which is compressed between the plate l3 and the collar l6 when the sleeve is threaded to the limit of its outward movement, as shown in Figure 3, whereby to form a leak tight joint between the collar and the plate. I

Upon the inner side of the wall I there is secured the substantially U-shaped frame, which is indicated as a whole by the numeral 18, and

which has the side portions 19 connected by the transverse bar 20 which is parallel with the wall I but spaced a substantial distance therefrom by.

the side portions [9. This frame l8 straddles the collar l6, as shown, and the bar 20 has secured to that side which opposes the wall 1, the conicalstopper or plug H which is provided with the screw threads 22 around the base portion thereof.

This plug 2! is designed to enter the inner end When the sleeve is threaded outwardlyto the position in which it is shown in Figure 3,'it will be readily seen that fluid from within the drum may enter the sleeve to flow outwardly 'therethrough. In order that any foreign matter which may be in the fluid may be prevented from passing through the sleeve the frame [8, which is horizontally disposed within the drum in close proximityto the bottom 24 thereof, is covered by a straining screen 25.

Upon the outer side of the wall 7 the sleeve has threaded thereon the lock nut 26 and encircling the sleeve and interposed between this nut and the outer side of the wall 1 is a gasket or washer 21. This nut 26 is employed to lock the sleeve against accidental turning when it has been threaded inwardly, as. shown in Figure 4, and the gasket 21 which is compressed between the nut and the-outer side of the'wall ,1, prevents leakage of fluid outwardly around the sleeve I5.

It will be noted, upon reference to Figure 4, that when the sleeve. is threaded inwardly so that the flow of fluid'from the receptacle is cut off, the outer end of this sleeve will be positioned, together with the nut 26 and washer 21, in the vestibule V. Consequently, the drum or receptacle may be rolled or otherwise shifted about without danger of'striking the sleeve and causing the joint between the sleeve and the plate l3 to be loosened with resultant leakage.

'I'he threading inwardly and outwardly of the sleeve is accomplished through the medium of the coupling employed for attaching a conduit, such as the hose 28, to the end of the sleeve. This coupling comprises a nipple 29 which has one, end extended into and secured to the hose 28 and which has its other end extended into one end of the coupling nut 30. The other end of this nut is interiorly threaded, as indicated and the coupling nut 30 is then threaded onto the 1 sleeve to form a tight connection therewith; By

then turning the coupling nut, hose and nipple, the sleeve l3 may be backed ofi of the plug 2| and the fluid will then pass directly through the sleeve into the hose. The sleeve can be threaded outwardly until the gasket I7 is compressed between the collar and the plate l3, whereupon a full flow of fluid from the receptacle through the sleeve will result without leakage of the fluid around the sleeve through the plate 13. Shutting off of the flow of fluid through the sleeve is accomplished by reversing the operation described, as willjbe readily apparent.

As previously stated, while the present invention has been shown applied to a large drum such as is commonly used for transporting oil understood that the invention may be applied to smaller receptacles and may be used in conjunction with receptacles having a means of forcibly ejecting the contents as well as those which have the contents'removed by force of gravity. Also, it will be readily apparent that the invention can bereadily installed in dI'lJll'lS or other receptacles which are already in use as well as being installed in such containers at the time of their construction.

It will be readily apparent that a particular advantage of the present invention resides in the fact that a drainage hose or drain faucet may be applied to the drum or receptacle so that the contents thereof can be drawn oif as desired,'

while the receptacle is filled and without running the risk of losing any'of the contents. There are receptacles which are provided with a place to install a faucet after a plug has been removed but the receptacle o'r'drum has to be shifted or placed in a certain position'beforeremoving the plug for the insertion of' the faucet, otherwise some of the contents will be lost. Withthe present invention, the faucet or hose can be attached while the outlet is maintained closed, after which the outlet can be opened and the fluid withdrawn as desired. a r

It is believed to be readily apparent that if de:

sired the plug 2| may be tubular and internally receptacle and having a threaded opening lead-.-'

ing into the receptacle, a tubular sleeve ,exteriorly threaded through the major portion of its length and engaged in said threaded opening to. be shifted axially into and out of the receptacle, a

collar upon the inner end of the sleeve adapted tov move into opposed relation with said wall forming means, a gasket-encircling the sleeve between the collar and the wall forming means, a locking nut threaded upon thesleeveat the outer side of the wall forming means, a gasket encircling the sleeve between the locking nut and the said wall forming, means, and a tapered plug supported within the receptacle coaxial with the sleeve in position to enter the inner end of the sleeve when the latter is threaded. inwardly a predetermined distance, 'to close the sleeve.

2. A drum having a circular wall, said wall at one end of the drum being cut away to form, an opening, a plate secured in the opening, said plate having a threaded opening therethrough, a. frame secured to the plate within the drum, a tapered plug carried by the frame and directed toward,

plate. I

3. A structure as set forth in claim 2, including a straining screen covering said frame through whichthe material in the drum must pass to the sleeve.

4. A drainage means for a receptaclecomprising in association with an opening formed in a wall of the receptacle, a plate for closing said opening and having a wall portion bordered by right angularly extending walls, said walls merging with a laterally directed encircling flange, the walls of the plate beingintroduced into said opening and saidflange positioning against the receptacle wall to be secured thereto, said plate wall having a central threaded opening, a sleeve threaded through said opening and having an encircling collar upon the inner end thereof, the

outer end of the sleeve being straight throughout, meansupon the inner side of said plate wall forming a support in spaced relation with the plate wall, a tapered plug supported on said support coaxial with said 'sleeve and adapted to enter the inner end of the sleeve when the sleeve is threaded inwardly through the plate wall, said sleeve flange limiting the outward movement of the sleeve, and a locking nut threaded upon the outer end of the sleeve and adapted to engage the outer side of the plate wall to maintain the sleeve in position when it has been threaded inwardly to the limit of its movement and closed by said plug, said plate walls forming a vestibule Within which the outer end of the sleeve and said locking nuts are disposed when the sleeve has been shifted to the limit of its movement inwardly.
