Abstract

An ornamental fountain nozzle for generating a plurality of nonaerated water streams includes a body defining a chamber therein. A plug is disposed across an upper water outlet opening of the body and has a portion of its length outside the body. A plurality of grooves are formed at intervals in the circumference of the plug and have their lengths substantially aligned with the length of the plug. The grooves have a substantial portion of their length disposed within the body. The grooves have lower ends which communicate with the chamber and upper ends which communicate with the exterior of the nozzle only through the peripheral walls of the plug above the upper end of the body. Each groove has a base element therealong located farthest inwardly of the groove from the plug peripheral walls. The base element of each groove is sloped outwardly relative to the length of the body proceeding upwardly along the groove. The grooves also have side wall surfaces between the groove base element and the adjacent peripheral walls of the plug, and these side walls converge toward each other proceeding upwardly along the length of the groove. Between the grooves, the plug peripheral walls are engaged in surface-to-surface contact with the interior of the body adjacent the top of the body so that the only outlet of water from the chamber between the plug and the body is via the grooves.
