Abstract
A quick disconnect coupler in which a plurality of jaw clamping units are supported around the periphery of a pipe section for clamping the flange of a second pipe section in engagement with the first pipe section. Each hydraulic unit includes a support member secured to the outer periphery of the pipe and a frame member slidably supported on the support member for sliding movement parallel to the axis of the pipe. An overcenter toggle linkage connects a jaw member to the frame member. A rotatable cam pivotally secured to the frame member engages a stop on the support member. One end of a hydraulic actuator is connected to the cam for rotating the cam while the other end is connected to the toggle linkage for moving the jaw. The actuator causes the toggle linkage to move the jaw into clamping engagement with the flange of the second pipe, while the other end of the hydraulic actuator rotates the cam whem the toggle linkage reaches the overcenter locked position. The cam slides the frame member in an axial direction to adjust for variations in the thickness of the flange being clamped by the jaw.
