Abstract
An adjustable oscillating sprinkler with a rectangular shaped frame having a generally tubular shaped housing rotatably attached to said frame with a nozzle strip attached to the tubular housing, where the nozzle strip has a plurality of flexible nozzles, and the sprinkler also has a pivot plate in contact with the nozzle strip and the tubular housing, where an adjusting element rotates the pivot plate about a radius of its longitudinal axis thereby adjusting the coverage pattern of the sprinkler.
Claims19
A sprinkling apparatus comprising:
- a generally rectangular shaped frame;
- a generally tubular shaped housing rotatably attached to said frame;
- a water operated drive attached to said tubular shaped housing;
- said water operated drive having a fluid intake portion;
- a nozzle strip in contact with said tubular housing,
- wherein said nozzle strip has a plurality of nozzles;
- a pivot plate in contact with said nozzle strip and said tubular housing,
- wherein said pivot plate comprises an adjusting tab and a plurality of grooves,
- wherein said plurality of nozzles protrude through said grooves of said pivot plate,
- wherein said adjusting tab is approximately located in a center of said pivot plate in a lengthwise direction and pivots the pivot plate in a circumferential direction with respect to a longitudinal direction of said housing,
- wherein an axis of at least some of said plurality of nozzles is varied as
- the pivot plate is rotated;
- a cover connected to said tubular housing,
- said cover comprises cover slots and cover grooves,
- wherein said adjusting tab protrudes through said cover slots and said nozzles protrude through said cover grooves.
An oscillating sprinkler apparatus having a frame, a tubular housing attached to the frame and a pivot plate sliding on said tubular housing, wherein said pivot plate guides adjustable nozzles in said sprinkler, wherein said pivot plate comprises:
- a series of apertures,
- wherein each of said apertures is formed with an incrementally increasing angle with respect to a lengthwise centerline of said pivot plate so that as each of said adjustable nozzles is tilted by a sidewall of said aperture, said sidewall remains substantially parallel to a cylindrical portion of said nozzle,
- wherein said pivot plate has an adjusting tab located in the center of said pivot plate in a lengthwise direction.
A sprinkling apparatus comprising:
- a frame;
- a housing rotatably attached to said frame;
- a nozzle strip attached to said housing,
- a pivot plate in contact with said nozzle strip and said housing,
- wherein said pivot plate comprises a plurality of grooves,
- wherein said pivot plate has an adjusting tab located in the center of said pivot plate in a lengthwise direction,
- wherein said pivot plate pivots in a circumferential direction with respect to a longitudinal direction of said housing,
- wherein an axis of at least some of a plurality of nozzles of said nozzle strip are varied as the pivot plate is rotated.
