Abstract
An oscillating sprinkler wherein a body structure carries a discharge nozzle and an oscillating mechanism which effects turning of the body structure in small increments. A control mechanism reverses the direction of movement of the body structure causing the body structure to move back and forth through a preselected arc. The body structure fixedly supports a metal pin on which the oscillating mechanism is journelled. The oscillating mechanism fixedly supports a metal pin in axial alignment with the metal pin on the body structure and the oscillating mechanism pivots on the end of the pin journelled into it with one end of the pin carried by the oscillating mechanism acting as a bearing surface. The pin carrried by the oscillating mechanism is journelled in a support plate that fastens to the body structure. One end of a spring member is attached to the portion of the oscillating mechanism pin that extends through the support plate. The other end of the spring member is moveably attached to the support plate allowing the spring force applied to the oscillating mechanism pin to be easily adjusted, as required, according to the prevailing water pressure. The spring member is shielded from the elements in a protective housing.
