    摘要： The adjacent extremities of two lengths of irrigation pipe are axially aligned in a spaced relationship within a longitudinally split, bolt closed coupler sleeve. The coupler sleeve has a diameter greater than that of the pipes and contains a one-piece sealing boot therein which sealably embraces the ends of the irrigation pipe. An open gimbal ring medially surrounds the coupler sleeve in a diametrically spaced relationship with respect thereto. Bracket members are mounted on the opposite sides of each pipe extremity in a longitudinally spaced relationship with respect to the coupler sleeve and a pair of arms extend from each bracket member to opposite pivotal connections with the gimbal ring, the axes of the pivotal connections of one pair being circumferentially spaced on said gimbal ring at 90.degree. from the pivotal connections of the other pair to enable the pipe lengths to freely, relatively and arcuately swing in any desired direction. A signal device is trained between the extremities of the pipe lengths to give a signal relative to the arc of swing between the extremities.
