SEUT FOR METALLIC REGEPTACLES.

Specification of Reissued Letters Patent. Reissued July 18, 1922,

Original No. 1,332,686, dated March 2, 1920, Serial No. 271,484, filed January 16, 1919. Applicationitor reissue filed February 7, 1921. Serial No. 443,308.

in Sputs for Metallic Receptacles, of which the following is a specification.

This invention relates to metallic receptacles, such as casks, barrels and the like having openings in the top or sides thereof the barrel.

for the passage of fluids, and more particularly 'to' an improved sput therefor, whereby the opening in-the receptacle may not only be reinforced, but made fluid tight, the object of the invention being to provide an improved sput which may be attached quickly in a simple and inexpensive manner without the necessity of welding it as is usual heretofore.

In the drawings accompanying and forming a part of this specification Figure 1 illustrates a cross section of the present improved sput'attached to a part of a metal barrel and the plug therefor, Fig. 2 illustrates the first operat1on of attaching the sput; and

shows a cross section of the die and punch,

Fig. 3 illustrates the second and final operation of attaching the sput, and also shows a crosssection of the die and punch; Fig. 4 is a plan view, of the top of the sput prior to its attachment. 7

Similar figures of reference indicate corresponding parts in the several figures of the drawing Various attempts have been made to reinforce and provide a fluid tight or leaf-proof sput opening for metallic receptacles, particularly metallic barrels, with more or less success, it being the usual practice, however, to weld, the sput to the barrel. The result of this mode of procedure has been frequently a lealfly joint around the opening of he present improvement not only does away with the necessity of this welding operation, while at the same time it reinforces the opening and positively prevents a leaky joint. 1 v

This improved sput 2 is'provlded with central bore 3 suitably threaded for the recep tion of aplug .4 and-its gasket 4. The sput may be of annular form or have hexagonal or other form of sides and is formed with a lateral or horizontally extending flange 5 and an upright or vertical integral locking" flange 6 between which an annular recess 7 is formed havlng a roughened or serrated portion 8 in its bottom adjacent tothe inner edge of such recess.

abrupt shoulder 9 around whichthe metal edge 10 of the barrel is bent and locked. In attaching this improved sput it is placed in a suitable die 11 with the edge 10 of the barrel openingin juxtaposition to the annular recess 7 of the sput and then by. means of a punch 12 the vertical integral locking flange '6 is first forced outward and downward substantially to the position shown in Fig. 2, the punch having the shape shown in said Fig. 2. Then by means of a second punch 13 having the shapeshown in Fig. 3

this vertical locking flange is forced further downward'over the edge 10 of the barrel opening thereby forcing such edge 10 firmly into the annular recess 7 and bending it around the shoulder 9 of such recess, and

also forcing the metal of the edge into engagement with the serrated portion 8, of the recess'which prevents any tendency of the sput to turn relative to the head or side of the barrel when a wrench is used to'remove or tighten the plug.

The vertical integral locking flange when forced down has its top or outer surface 14 substantially flush with the metal of the barrel, and as this flange is of curved or beaded form it provides a neat and pleas ing finish around the barrel opening.

Preferably the flange terminates at its base in a shoulder 15 which facilitates the formation of a bendable locking flange.

Thus, I am enabled by a couple of punchingoperations, to, as it were, cold weld the metal body edge into. the annular recess of the sput and lock the same therein by means of a locking flange forced down upon the metal of the body in such a manner that the free edge of the flange will be flush with, or slightly below the shoulder 16 of the barrel metal formed by its bend over the relatively abrupt shoulder 9 of the sput, so that the edge of the barrel opening will have substantially an ogee bend and. any possibility of the barrel pulling away from its locking recess and flange prevented, not

The recess'terminates in a comparatively this simple mode of procedure through the medium of this improved sput, moreover the sput is firmly held against rotatable movement on the application of a wrench" to the plug or closure either to release 'or ti hten the same.

t is to be understood that by the expres- "sions bottom wall or bottom face is meant that surface adjacent the bottom of the recess in the sput, irrespective of whether the osition of the receptacle as a whole be sue as to direct that surface upwardly .or downwardly.

I claim as my invention:

1. A sput for a metallic receptacle having an annular flange, andan integral vertical bendable locking flange having" therebetween the annular recess provided with a shoulder, said sput having means in position to engage the bottom wall of the free edge of the receptacle adjacent to the opening thereof thereby to prevent the rotation of the sput relatively to the receptacle,

2. A sput for a metallic receptacle having an annular flange, and an integral vertical bendable locking flange having therebetween an annular recess, said recess having a 'serrated bottom portion in position .to engage the bottom wall of the free edge of the receptacle adjacent to the opening thereof thereby to prevent the rotation of the sput relatively to the receptacle.

3. A metallic receptacle having an opening, a sput having a laterally extending flange, and an integral bendable locking flange having therebetween an annular r ecess with the edge of the opening clamped in said recess by said lockin flange, said recess also having a shoul er around which the edge of the receptacle is bent, and said sput, having means in position to'engage the bottom wall of the free edge of the receptacle adjacent to the opening thereof thereby to prevent the rotation of the sput relatively to the receptacle.

4. A metallic receptacle having an opening, a sput having a laterally extending flange, and an integral bendable locking flange having therebetween an annular recess with the edge of the opening clamped in said recess by said locking flange, said recess also having a roughened or serrated portion into engagement with which the bottom face adjacent to the free edge of the receptacle opening is forced.

5. A. metallic receptacle having an openmetal of the receptacle is bent, said sput also ing, a sput having a threaded bore, a laterally extending flange, and an integral bendable locking flange having therebetween an annular recess having an abrupt shoulder, said recess having means in position to engage the bottom wall of the free edge of the receptacle adjacent to the opening there-. of thereby to prevent the rotation of the sput relatively to the receptacle, the metal of the receptacle being clamped in said recess by bending the locking flange over the edge of such metal.

6. A metallic receptacle having an opening, a sput having a threaded opening, a laterally extending flange, and an integral bendable locking flange having therebetween an annularrecess having an abrupt shoulder, said recess having means'in position to engage the bottom wall of the free edge of the receptacle adjacent to the opening thereof thereby to prevent the rotation of the sput relatively to the receptacle, the metal of the receptacle being clamped in said recess by bending the locking flange over the edge of such metal and the surface of the locking flange being substantially flush with the surface of the adjacent metal.

7. A receptacle having an annular opening, a sput having an annular recess for the reception of the edge of such opening, and 95 an integral bendable locking flange clamping the metal edge of the receptacle into the recess of said sput, said recess terminating in' an abrupt shoulder around which the having means in position to engage the bottom wall of the free edge of the receptacle ad acent to the opening thereof for preventing the rotation of the sput relatively to the receptacle. i it 8. A metallic receptacle having an opening, and a sput therein having a threaded opening and provided with a recess about the same within which the edge portion of said receptacle rests, the engaging parts of said edge portion and said sput being shaped to interlock against relative rotation and said sput being rovided with an overlapping part whiciigrips said edge portion in said recess and holds it in interlocking, relation.

9. A metallic receptacle having an opening, and a sput therein having a threaded opening and provided with a recess about the same into which the edge portion of said receptacle is forced out of its plane, the engaging surfaces of said edge portions and said sput being shaped to lie at varying distances from the axis of the sput whereby they are held against relative rotation, and said sput being provided with a flange which is bent to grip said edge portion in said recess and hold said engaging surfaces in said relation. j j

10. A metallic receptacle having an openposition. in said 5 ing therein, and a sput fitted within said opening and provided with a recess offset with respect to the plane of the adjacent portion of the receptacle and with a bendable flange, the edge portions of said receptacle being forced into said offset recess and into 7 engagement with interlocking irregularities formed on the split, and said flange on said sput being bent to grip said edge portion within said recess and hold it in said inter- 10 looking relation.
