Abstract: An adjustable water nozzle apparatus is disclosed including a generally tubular first conduit portion that is communicably interengaged with the water supply line. A generally tubular second conduit portion has a discharge outlet. A generally tubular, longitudinally flexible bellows portion communicably interconnects the first and second conduit portions. The bellows portion is longitudinally flexed to angularly adjust the second conduit portion relative to the first conduit portion. The bellows portion is sufficiently rigid to hold the second conduit portion in an angularly selected orientation relative to the first conduit portion such that water is directed through the nozzle apparatus and discharged from the outlet in a selected direction.

Abstract: A system utilizing at least three separate water pumps for supplying water under pressure to a plurality of nozzles in a fountain display which provides a wide variety of spray heights of the various nozzles. The nozzles are spaced along a main water supply pipe and the pumps are connected to the main water supply pipe at spaced apart entry points along the pipe with a one-way check valve between each pump and the mainwater supply pipe. An independently controllable and incrementally variable gate valve is also located between each pump and the main water supply pipe. Additional versatility and variety of the sprays projected from the nozzles can be obtained by use of additional check valves located along the main water supply pipe between each of the entry points of water supplied by the pumps which pass water under pressure only in one or the other direction.

Abstract: Mechanism for adjustably moving two separate series of water fountain nozzles. The mechanism includes a pair of elongated push rods being driven in opposite directions by a single electric motor having two eccentric arms. The push rods are each separately connected to a spaced series of fountain nozzle assemblies by a slip ring adjustably connected to an elongated length of pipe forming part of each nozzle assembly. By varying the location of the slip ring along the length of the nozzle assembly's pipe, infinite variations in the extent of the arc through which the nozzle's tip will sweep during oscillation of the push bars is achieved.

Abstract: An arrangement of water pumps comprising two electric motor operated pumps for each of a plurality of formations of nozzles whereby the water flow from the pairs of pumps to the various formations of nozzles may be selectively controlled by pluralities of electric switches located in a remote station. Electric circuitry associated with the switches controls the electric current flow to the various pump motors in a manner whereby the height of the water sprays emitted from the respective nozzles is selectively controlled along with providing a generally universal control over the activation of individual, various groups and formations of nozzles to produce a very wide range of different rhythmic visual effects.
