METHOD OF SECURINGBUNG Busames iled Aug. 7, 1933 v l 24 2.? 2a

i ea 65 INVENTOR Patented Feb. 9, 1937 UNITED STATES PATENT OFFICE 3 Claims.

The present invention pertains to a method of securing'bung seat or bushing in a barrel wall and is particularly adapted for assembling bung bushings in double walled metal barrels or containers for the purpose of providing a bung opening through which the barrel or container may be filled with a beverage or through which the beverage may be removed, and means for receiving or seating a bung or stopper for sealing the barrel or container.

In metal barrels of conventional construction an inner container is surrounded by an outer, protective wall, sufiiciently strong and durable to stand considerable rough usage. A bung bushing ordinarily extends through the outer wall and into the inner container for the purpose of re-- ceiving and seating a bung to seal the inner con: tainer. When it is desired to remove the bung, the ordinary procedure is to drivethe same through the bushing into the barrel by blows with a hammer or mallet.

' The primary object of the present invention is.

formed of aluminum and the outer wall is formed of steel. In such construction it is desirable to join the bushing, which is formed of aluminum, to the inner aluminum wall by welding, and this invention provides a method of assembling the bushing in the steel wall whereby itssupport will be. suificientlystrong to support the bushing so that when blows areimparted to a bung therein the shocks of such blows are not imparted to the aluminum wall. Aluminum linings are desirable in barrels for containing such beverages as beer because they can be easily cleaned with steam, the metal does not spoil the taste of the beer, the aluminum will not rust, and necessity for pitching the barrels is eliminated.

With the above and other ends in view the invention consists in matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which- Figure 1 is a top plan view of the present bush- (ores-148.2)

ing, illustrating a fragment of a barrel wall in which it is mounted;

section taken on line Fig. 7 is a section of a bung bushinghaving a Between the screwthreaded portion 2 and the flange 3 is formed a circumferentially extending groove 4. The numeral 5 designates the inner wall or lining of a barrel, this wall or lining preferably being formed of aluminum. Thebushing I is also .formed of aluminum and the integral flange 3 thereon is received'in an opening 3 in the inner wall or lining 5. The flange 3 is welded to the wall or lining 5 as indicated at I.

An outer, protectivewall, preferably formed of steel in order to provide strength and durability, is formed in two sections 8 and 9 having semicircular grooves III and II respectively in their meeting edges... The two sections 8 and 9 are united by welding along the seam l2 while the edges of the recesses l0 and l l project into the groove 4. The diameter of the circular opening, formed by uniting the. two

sections

3 and 3 and the complemental recesses, is smaller than the diameter of the screwthreaded part 2 and the 5 may be filled with insulating material such as" cork or it may be filled with air. This space is sealed around the bushing l by a gasket or sealing ring I4 which is interposed between wall sections 8 and 9 and a washer I5. 'A ring nut i6 is received on the screwthreaded portion 2 and is tightened to compress the sealing ring H. Prior to screwing on the nut li the screwthreaded portion 2 is coated with a compound which prewardly extending rim-flange 22. The rim-flange 22 extends into an opening.23 in an inner wall or lining 24 of a double walled barrel or container, the lining preferably being formed of aluminum. The bushing 20 is also formed of aluminum and the flange 22 is welded in the opening 23 as designated at 25. An outer wall 26, preferably formed of steel, is provided with an opening 21 through which the bushing 20 extends. Surrounding the outer wall 26 is a band 28 having its meeting edges welded together along the seam 29. The meeting edges of the band are formed with complemental semi-circular grooves 30 .which combine to form a circular opening encircling the bushing 'and received in a circumferentially ex tending groove 3| in the bushing. The band 28 is then welded to the outer wall 26.

Placed over the bushing 20 is a sealing ring 32.upon which rests a washer 33, and a ring nut 34 is screwed on the threaded portion of the bushing to compress the sealing ring 32. The nut 34 is preferably secured in its tightened position to positively prevent removal thereof.

The descriptive matter relating to Figs. 3 and 4 is illustrative of the application of the present method of assembling a hung bushing in a barrel having an opening in the outer wall through which the bung bushing extends, the latter being supported in a reinforcing band so that shocks received by the bushing are carried by the band without imparting the same to the lining wall.

In Fig. 5 the numeral designates an inner wall or lining having an opening receiving a flange 4| on a bushing 42. Both the bushing and lining 40 'are preferably formed of aluminum. The lining 40 and flange 4| are welded together as designated at 43. An outer steel wall 44 has a depressed portion 45 formed with an opening 46 through which the bushing 42 extends. The portion 45 of the wall 44 rests upon the top of the flange 4| and has a sealing ring 41 resting on the I top thereof. Engaging the sealing ring 41 is a washer 48 which is engaged by-a nut 49 on the screwthreaded end 50 of the bushing. By tightening the nut 49 the sealing ring 41 and wall portion 45 are tightlvinterposed between the flange .4! and washer 48.

This disclosure illustrates the application of the present invention to a barrel having an opening in the outer wall thereof and for supporting the bushing so as to relieve the lining 40 of any shocks. In this particular instance the wall 44 is illustrated as having a rubber covering 5!.

In Fig. 6 the method of assembling the bushing is the same as disclosed in Figs. 1 and 2 with a slight modification in that the outer wall sections are depressed. adjacent the semi-circular recesses therein to provide a wedge shaped surface 60 for compressing the sealing ring I inwardly at the same time it is compressed downwardly by the washer 62 and nut 63. In this instancethe bushing 64 which receives the nut 63 is also formed ing in an aluminum lining 66. The outer wall sections are designated at 1 and'project' into a circumferentially extending groove 68. With the exception of the wedge surface this disclosure is identical with Figs; 1 and 2 which are described in greater detail.

From the foregoing it becomes apparent that the present invention provides method of mounting a hung bushing in a double walled barrel, or in other words, a barrel having an aluminum lining, so that shocks received by the bushing are not imparted to the lining. Furthermore, it becomes apparent that the present method provides for mounting a bung bushing in any double walled container, and it is equally'applicable for mounting in the side or the head of a barrel.

In Fig. 7 there is illustrated an aluminum bung bushing 10 constructed to be welded to an aluminum lining and to be attached to the steel outer wall according to the method set for th above.

The bushing 10 is internally threaded as at H to 4 receive an externally threaded tap bushing I2. The tap bushing 12 has a spindle 13 provided with a central opening 14 and an interrupted flange 15 for attachment of a tapping apparatus thereto in the manner'well known in the art.

Although specific embodiments of the present invention have been illustrated and described it is to be understood that various changes may be I, made within the scope of the appended claims ings extending into the groove.

2. The method of securing a bushing in a wall which consists in providing the bushing with a groove, forming said wall in two parts and providing the meeting edges thereof with complemental recesses, drawing the two parts together and causing the part of the wall immediately adjacent the recesses to enter the groove in the bushing, and integrally uniting the two parts of the wall.

3. The method of securing a bushing in a wall which consists in providing the bushing with a groove, forming a pair of plates with complemental openings, uniting said plates while holding the part .thereof immediately adjacent the recesses in the grooves in said bushing, providing a wall .with an opening therein, and securing said plates to said wall with the end of the bushingin said opening.
