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. ### Claim 2 (depends on 1) The sprinkling apparatus according to claim 1 wherein an angle of at least some of said pivot plate grooves varies with respect to the angle formed between the pivot plate grooves and the longitudinal axis of said pivot plate. ### Claim 3 (depends on 1) The sprinkling apparatus according to claim 1 wherein at least one of said nozzles is fixed in a substantially vertical direction. ### Claim 4 (depends on 1) The sprinkling apparatus according to claim 1, wherein said pivot plate grooves increasingly slant outward with respect to a middle portion of said pivot plate. ### Claim 5 (depends on 1) The sprinkling apparatus according to claim 1 wherein said adjusting tab comprises a pair of tabs formed one each on an opposing side of said pivot plate. ### Claim 6 (depends on 1) The sprinkling apparatus according to claim 1, wherein said tubular housing has at least one elevated rib, wherein said elevated rib supports said pivot plate. ### Claim 7 (depends on 1) The sprinkling apparatus according to claim 1, wherein some of said plurality of nozzles of said nozzle strip incrementally flare outward as said nozzles increase in distance from a center of said nozzle strip. ### Claim 8 (depends on 1) The sprinkling apparatus according to claim 1, wherein said cover grooves further comprise generally circular cover outlets, where said nozzles protrude through said cover outlets. ### Claim 9 (depends on 8) The sprinkling apparatus according to claim 8, wherein a width of said cover grooves is approximately equal to a width of corresponding said nozzles. ### Claim 10 (depends on 1) The sprinkling apparatus according to claim 1 wherein a diameter of said circular cover grooves are approximately equal to an outer diameter of said nozzles, wherein said circular cover outlets limit movement of said corresponding nozzles in a lateral direction. ### Claim 11 (depends on 4) The sprinkling apparatus according to claim 4, wherein said grooves comprise a sidewall having an angled surface so that a sidewall of said groove remains substantially parallel to a nozzle axis as said sidewall moves the nozzle axis. ### Claim 12 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. ### Claim 13 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. ### Claim 14 (depends on 13) The sprinkling apparatus according to claim 13, wherein an angle of at least some of said pivot plate grooves varies with respect to the angle formed between the pivot plate grooves and the longitudinal axis of said pivot plate. ### Claim 15 (depends on 13) The sprinkling apparatus according to claim 13, wherein at least one of said nozzles is fixed in a substantially vertical direction. ### Claim 16 (depends on 13) The sprinkling apparatus according to claim 13, wherein said pivot plate grooves increasingly slant outward with respect to a middle portion of said pivot plate. ### Claim 17 (depends on 13) The sprinkling apparatus according to claim 13 wherein said adjusting element is located on opposite sides of said pivot plate. ### Claim 18 (depends on 13) The sprinkling apparatus according to claim 13, wherein said tubular housing has at least one elevated rib, wherein said elevated rib supports said pivot plate. ### Claim 19 (depends on 13) The sprinkling apparatus according to claim 13, wherein some of said plurality of nozzles of said nozzle strip incrementally flare outward as said nozzles increase in distance from a center of said nozzle strip.
