ABSTRACT:
An oscillating sprinkler is specially designed to facilitate assembly, as well as disassembly for purposes of repair of replacement of parts, without sacrifice of water-tight integrity and with improved operating characteristics. The housing for the impulse wheel and for supporting one end of the sprinkler tube is formed of two parts snapped together to effect the necessary seal, the sprinkler tube is mounted therein by a snap action insertion, thereby to define an operating subassembly, and that subassembly is reliably assembled with a mounting subassembly by sliding insertion and snap action retention. The sprinkler tube is sealingly journaled in such a manner as to produce very low friction, thus reducing the load on the impeller wheel and enabling the sprinkler to have a very low pressure drop therethrough, thereby increasing the sprinkling range of the device. The linkage between the impeller wheel and the sprinkler tube is manually accessible and is provided with a snap connection so that the linkage can readily be manually disconnected and connected. The construction lends itself to producing a low-profile, low cost unit.
