发明名称 Split ring assembly to lock a cam pipe coupling
摘要 A split ring assembly for maintaining a releasable pipe coupling, of the type having a female portion having two pivoted opposite cam lever arms and a circumferentially grooved male portion, in an engaged position comprising: two generally semicircular ring portions hinged together on one side and provided with a latch mechanism on a diametrically opposite side; wherein each ring portion is notched to receive a swinging end portion of one of the cam lever arms; and wherein each ring portion is sized to closely surround the female portion of the pipe coupling. Then when the ring assembly surrounds said female portion and the pivoted arms, closing the latch mechanism visibly ensures that the coupling portions remain locked together. The split ring assembly is a rugged visibly convincing assurance that a coupling will not inopportunely open. It can be manipulated by an operator wearing heavy gloves in subzero weather or during a snow storm.
