Patented Oct. 22, 1929 UNITED CHARLES L. HUNT AND NETTER J'. HILL, OF ST. LOUIS, MISSOURI, .FASSIGNORS TO NON- REFILLABLE CONTAINER, INC., OF ST. LOUIS, MO., A. CORPORATION 0F MISSOURI` LIQUID CONTANER Application mea July 11,

improved valve device for use in connection with liquid containers 'comprising a pipe eX- tending through the top of the container to- `ward the bottom and having its lower end open and equipped with means for supporting a valve seat, in combination with a support equippedY with a valve seat and a valve and means for removably supporting the support and thereby the valve within said pipe.

:Another object ofthe invention is to provide a device for replacing and removing said support from the pipe. l l

Other objects will appear from the following descriptiom'reference being made to the drawing in which .f l A Y Fig. 1 is a view .showing a Vcontainer equipped with thepresent invention.

'Figi 2 is an enlarged vertical sectional view of the invention.

Figs. 3 and 4 are cross sectional views on the lines 3-3 and 4 4, respectively, of Fig. 2.

Fig. 5 is a sectional view ','howing adevice for inserting and removing the valve support from the pipe through which the container is filled and emptied. Y

The container in which the invention is shown is a barrel of familiar construction comprising a shell 1, a top wall 2 and a bottom wall 3. 1

A pipe 4 extends through a hole in the top 2 -to the bottom 3. An impervious joint beiy tween the top wall 2 and theupper end ofthe pipe 4 may be obtained by a ring of solder 5 applied at the joint. The lower end of the pipe 4 has a number of notches 6 so as to permit the liquid contents of the container to be withdrawn through the pipe 4 or to permit the container to be refilled. The inside of the pipe 4 at its upper end is threaded and is closed by a removable plug 7 during shipment or when the container is in storage.

1928. Serial No. 291,718.

'This plug'm'ay'be removed and the usual4 threaded attachment of a pump (not shown)v may be screwed in place of the plug to withy l draw the liquid contents of the container.

A'sleeve 8 is secured within thelower end of the `pipe 4 above the notches 6. This sleeve is not rotative within the pipe. A cotter pin 9 extends diametricallythrough the lower ends of the pipe'4 and the sleeve 8 and, if desired, this cotter pin may function to support and hold vthe sleeve 8 from rotation in the pipe. Or, the sleeve may be otherwise held is internally` from rotation. The sleeve 8 threaded atits upper end. Y

A Vtubular valve support 10 is exteriorlyI threaded at its upper end and is insertable in the sleeve 8 until the threads on the outuntil the lower end'of said support abutsVV against the Cotter pin v9 and prevents further rotation of `said support 10 in the direction v in which it must be rotated screwed into the sleeve 8. j Some distance below its upper end the supwhen'it is ybeing the support 10 has a valve stem guide 13. A' valve stem 14 extends throughthe guide 13 and on its upper end is equipped with a Valve l port 10 is formed with'a valve seat 11 having f an opening 12; and below the valve seat 11,

15 movable to and from the seat 11 to close and toopen the opening 12. Y The valve stem 14 has a nut 16 screwed on its lower end below` the guide 13 and this nut serves to limit move- 'Y ment of the valve 15 toward open position.

The device for inserting and withdrawing the valve device is shown in Fig. 5, the same comprising a rod 17 having a plug 18 atto be screwed into engagement with threads 19 on the inside of the upper end of the support 10 Iabove the valve seat 11. These threads 19 are formed oppositely from ythe threads on the outside of the support '10 so that vthere will be no difficulty in using the device '17-18 to vinsert and to remove the support 10. Lugs 2O at the lower end of the threads 19 constitute abutments for the'plug tached to one end and designed Vand adapted 18 to prevent the same from being screwed so far into the support 10 as to become rigid. The rod 17 has one or more discs 21 functioning as guides when inserted within the pipe 4 so as to hold the rod 17 aXially within the pipe. A handle 22 is in connection with the upper end of the rod 17.

Initially the container 1 is filled with oil or other liquid through the pipe 4 before the valve support 1() is inserted, it being understood that the upper end wali 2 is provided with the usual vent (not shown). After the container 1 is `{illed the support 10 screwed on the plug 18 is passed downwardly through the pipe 4 until the threads on the outside of the upper end of the support 10 engage the threads on the inside of the upper end of Vthe sleeve 8, When said threads are brought into abutting contact the handleV 22 is operated to rotate the rod 17 and thereby the'plug 18 and the support 10 which is screwed on said plug. Suc-h rotationis in a direction necessary to screw the support 10 into the sleeve 8 and continues until the lower end of thesupport lOvabuts against the cotter pin 9. Then continued rotation of theV plug 18 in the same direction unscrews theY same from the support 10 and the plug, together with the rod '17, is withdrawn from the pipe 4. Then the plug 7 is applied and kept in connection with the device so long as the container is in shipment or in storage.

When it is desired to withdraw the liquid contents of the container the plug 7' is ref -moved and a pump is secured in connection with the upper end` of the pipe 4 in the saine way that the pump is usually attached to the opening inthe top of an oil barrel. When the pump is operated the valve 15 will, of course, be raised, permitting the liquid contents of the container to be pumped out. But, thefcontainer cannot be refilled so long as the valve support 10 remains in position in the pipe, for the valve 15 prevents inflow of liquid. When it is desired to rell the contai1ie1"t.he device 17e-'18 must be screwed into engagement with the threads 19 and continuoilsly rotated until the support 10 is unscrewed from the sleeve 8. ihen the support 10 becomes disengaged from the threads on the sleeve 8 the attaching and detaching tool may be withdrawn and with it the support 10 will be withdrawn from the pipe 4. Then, it is apparent that the container may be refilled.

The construction, arrangement and relationship .of the parts may be varied within equivalent limits without departure from the nature and principle of the invention. Y

We do not restrict ourselves in unessential respects, but` what we claim and desire to secure by Letters Patent is 1. In a container having upper and lower end walls, a pipe extending through one of said walls toward the other, a valve support, a threaded element for supporting said valve support within the inner end of said pipe, an abutment for the inner end of said valve support, a valve seat in said valve support, a valve movable to and from said seat, and means for guiding said valve.

2. .ln a liquid container having upper and lower end walls, a pipe extending from the upper end wall toward the lower end wall, internal screw threads within the lower portion of said pipe, a cylindrical Vvalve support, external screw threads on one end of said valve support screwed into said first-named screw threads, a valve supported within said valve support, and a device for operating said valve support to screw the saine in position and to unscrew the same for removal from said pipe.

3. Tn a container having opposite end walls, i

a pipe exten-ding through one of said end walls toward the other andhaving lateral openings at its inner end, a sleeve Isecured within the inner end of said pipe above said openings, a cylindrical valvev support relnov` ably supported in said sleeve, an abutment limiting extent of inward' movement of said valve support in said sleeve, and a valve supV porte'din said valve support. v Y

4. In a container having opposite end walls, a pipe extending through one of` said i end walls towardy the other and having lateral openings at its inner end, a sleeve `secured within the inner end of said pipe ,above said openings, a cylindrical valve support remove vably supported in said sleeve, an abutment limiting extent of inward movement of saidV valve support in said sleeve, a valve supported in said valve support, and means in the outer end of said valve support outwardly beyond said valve for engaging with ,apositionin and removing tool. having upper and lower 5. In a container end walls, a pipe having its upper endopening through one of said end walls and extending downwardly'toward the other and ope-ning laterally into said container near said other end of said container, ,a cylindrical valve support of less diameterthan the insideof said pipe betweenl said support and the upper end of said pipe screwed into said pipe near the end of said pipe which opens latere ally into said container as aforesaid, means?,

limiting extent of movement of said valve support toward said other end of said container and preventing said valve support from closing communication from said pipe to said container, and a valve supported within said valve support. p CHARLES L. HUNT. NETTER J. HILL.
