ABSTRACT:
A steel closure ring assembly for a barrel or drum of the split ring type that is adapted to close the chime of a barrel and its cover. A pair of metal fittings, one on each end of the ring, tighten the ring and swage it around the barrel to make a tight, liquid-proof seal even under drop test conditions.
Each metal fitting incorporates a machine nut with a folded metal housing enclosing its exterior sides while leaving the interior or threaded sides accessible. The nut may have four or six sides with an arcuate member extending from one side in an outward direction or in a direction away from the encapsulated nut, which is adapted to closely conform to the curved metal ring and thereby extend over the chime of the barrel.
A tang extends from the sheet metal housing to the side of the fittng away from the end of the split ring and also over the chime and is attached by means of welding.
