An elongated horizontal conduit is provided having one open end and an upwardly opening and upwardly projecting receiver at its other end. The receiver is elongated longitudinally of the conduit and includes a pair of opposite side walls interconnected at their opposite ends by integral end wall portions. The side walls closely oppose each other and control structure is provided whereby the mid-portions of the upper marginal edges of the side walls may be bowed outwardly. The control structure is operable from adjacent the open end of the conduit and the latter functions not only to drain off liquids received by the receiver, but also as a handle for properly positioning the receiver relative to a point of discharge of liquid to be received by the receiver.
