Adjustable arc, adjustable flow rate sprinkler

A sprinkler head comprising a base;

• an elongated stem supported within the base;
• a nozzle and a stream deflector supported within the stem, said nozzle and stream deflector cooperating to define an arcuate orifice;
• a water distribution plate supported on a shaft extending upwardly from said base, said water distribution plate located in axially spaced relationship to said nozzle and adapted to be impinged by a stream emitted from the nozzle;
• and
• an adjustment throttle member secured to an upstream end of said shaft such that rotation of said shaft causes said throttle member to move axially relative to a flow restriction portion, to thereby adjust flow rate through said nozzle and a throw radius of the stream emitted from said nozzle.

A sprinkler head comprising a base;

• a nozzle and a stream deflector supported within the base, said nozzle and deflector cooperating to define an adjustable arcuate orifice;
• a water distribution plate supported on a shaft extending upwardly from said base, said water distribution plate having a plurality of water distribution grooves therein located in axially spaced relationship to said nozzle and adapted to be impinged by a stream emitted from the nozzle;
• an arc adjustment ring rotatably mounted on said base, said arc adjustment ring operatively connectable with said nozzle for rotating said nozzle relative to said steam for adjustment of said arcuate discharge orifice;
• and
• a throttle member secured to an upstream end of said shaft such that rotation of said shaft causes said throttle to move relative to a flow restriction portion, to thereby adjust flow rate through said nozzle and a throw radius of the stream emitted from the nozzle.

An adjustable arc sprinkler head comprising a substantially cylindrical housing;

• a stream deflector supported in said housing;
• a nozzle located on said stream deflector and rotatable relative thereto, said nozzle having a first arcuate edge;
• wherein said stream deflector has a substantially hourglass shaped portion, tapering inwardly upstream of said first arcuate edge and tapering outwardly downstream of said first arcuate edge, thereby establishing a second arcuate edge radially inwardly spaced from said first arcuate edge and defined by a smallest diameter of said hourglass shaped portion;
• said first and second arcuate edges defining an adjustable discharge orifice having an arcuate length, a downstream end of said stream deflector having a radially extending vertical tab with a first vertical surface forming one end of said adjustable discharge orifice, and a second vertical surface on said nozzle forming a second end of said adjustable discharge orifice, said first and second ends movable relatively toward and away from each other to thereby vary said arcuate length of said discharge orifice.

A pop-up sprinkler assembly comprising a first tubular member having an inlet end adapted for connection to a source of water under pressure;

• a second tubular member slidably mounted within said first tubular member and including a sprinkler head;
• a first coil spring located within said first tubular member arranged to bias said second tubular member to a retracted position within said first tubular member, said second tubular member movable to an extended position when water under pressure is admitted to said inlet end;
• said sprinkler head including an elongated stem;
• a nozzle supported on said stem;
• a water distribution plate mounted on a shaft projecting upwardly through said nozzle, said nozzle and said water distribution plate extendable relative to said second tubular member to an operative position;
• a second coil spring located in said sprinkler head, radially outwardly of said nozzle, supported at one end by a downstream end of said stem, and arranged to bias said water distribution plate to an inoperative position relative to said second tubular member.

A pop-up sprinkler assembly comprising a first tubular member having an inlet end adapted for connection to a pressurized water source;

• a second tubular member slidably mounted within said first tubular member for movement between retracted and extended positions;
• a first coil spring located within said first tubular member arranged to bias said second tubular member toward said retracted position within said first tubular member, said second tubular member movable to said extended position when water under pressure is admitted to said inlet end;
• a sprinkler head including a tubular base at an upper end of said second tubular member;
• an elongated stem supported within the base;
• a rotatable nozzle and a stream deflector supported within the stem, said nozzle and stream deflector cooperating to define an adjustable arcuate discharge orifice;
• a rotor plate supported on a shaft extending from said stem, said rotor plate having a plurality of water distribution grooves therein located in axially spaced relationship to said nozzle and adapted to be impinged by a stream issuing from the nozzle;
• an arc adjustment ring rotatably mounted on said base, said arc adjustment ring operatively connectable with said nozzle for rotating said nozzle relative to said stem for adjustment of said arcuate orifice;
• and
• a second coil spring radially outward of said nozzle and extending between a downstream end of said stem and said arc adjustment ring to thereby bias said rotor plate toward an inoperative position within said base, and movable to an operative position axially spaced from said base when water under pressure is admitted to said inlet end;
• and
• a throttle member secured to an upstream end of said shaft such that rotation of said shaft causes said throttle to move relative to a flow restriction portion of said stem, to thereby adjust flow rate through said nozzle and a throw radius of the stream emitted from said nozzle.

A sprinkler head comprising a base having an upper end and a lower end, said lower end adapted for attachment to a sprinkler component;

• an elongated stem supported within the base and movable between retracted and extended positions;
• a nozzle and a stream deflector supported within the stem, said nozzle and deflector cooperating to define an arcuate discharge orifice adjustable through a predetermined arc;
• and
• an arc adjustment ring rotatably mounted on said base, said arc adjustment ring operatively connectable with said nozzle for rotating said nozzle relative to said stream deflector for adjustment of said arcuate discharge orifice;
• and wherein said arc adjustment ring is operatively connectable with said nozzle only when said stem is in said operative extended position.

A sprinkler head comprising a base;

• a nozzle and a stream deflector supported within the base, said nozzle and stream deflector cooperating to define an adjustable arcuate discharge orifice;
• a water distribution plate supported on a shaft extending upwardly from said base, and adapted to be impinged by a stream emitted from the nozzle;
• and
• means for effecting relative movement between said nozzle and said stream deflector for adjusting an arcuate length of said discharge orifice.
