Abstract: A rotational indexing nozzle arrangement has been devised wherein positive and consistent indexing action takes place under the influence of the application of fluid pressure and its relief by the action of an indexing or biased spring which becomes relaxed during the first stage (outward) movement of the indexing of the rotational nozzle head and which bites in and holds thereby causing the nozzle head to rotate during the second stage (inward) movement of the discharge head. The extent of the incremental indexing is determined by the length and angle of the biasing spring, or member. For improved operation a bearing of the ball or roller type may be disposed at the inward end of the nozzle arrangement whereby the resistance of the closing spring to rotation of the nozzle head is lessened.
