Abstract
A coupling nut (300) mounted to a first shell (100) for connection to a threaded second shell (200) comprises: an operating sleeve (600) rotatably circumposing inner front and rear coupling sleeves (400, 500) having their adjacent ends threadedly interconnected; a roll bar (700) operatively driven by operating sleeve (600) for engaging spaced end faces on respective coupling sleeves to cause relative rotation therebetween; and a coil spring (800) for constantly biasing the coupling sleeves (400, 500) into a first position, right-handed thread (220, 420) operating between second shell (200) and front coupling sleeve (400) and left-handed thread (430, 530) operating between the coupling sleeves (400, 500), coupling rotation beyond mating engagement between the assembly by the right-handed threads causing coil spring (800) to compress and transmit uncoupling rotation to the left-handed threads whereupon the coupling sleeves separate and further coupling rotation of the right-handed thread, uncoupling rotation of the front coupling sleeve having the right-handed thread simultaneously causing the coil spring to urge the separated rear coupling sleeve with left-right-handed thread into t…
