Abstract
Abstract A modified spout, for use in steel grain-loading hoses, is provided. The spout includes a circumferential channel attached to its outer surface. A hinged split ring, having a locking clamp, is provided within the channel. The clamp functions to lock the ring in place. The ring carries apertured lugs which can be pinned to the two chains running along the sides of the hose to suspend the spout as part of the hose. When the spout is worn through by the flow of abrasive grain, the clamp is undone, the spout is rotated within the ring to present a fresh surface to the grain flow, and the clamp is then tightened to lock the ring and spout together again.
