Stream propelled rotary pop-up sprinkler with adjustable sprinkling pattern

A pop-up, rotating stream sprinkler device comprising:

• an outer housing having a substantially closed lower end and an open upper end, including an inlet in said closed lower end adapted for connection to a source of liquid under pressure;
• a first inner housing telescopically and concentrically mounted within said outer housing, having an outlet end provided with a first arcuate slot adapted to discharge a stream of liquid under pressure;
• a distributor mounted on one end of a shaft for rotation relative thereto, said distributor located downstream of said outlet;
• and
• a nozzle disk rotatably secured to said first inner housing and provided with at least one discharge orifice, wherein said nozzle is rotatable to align any part of said at least one discharge orifice with said first arcuate slot.

A pop-up, rotating stream sprinkler device comprising:

• an outer housing having a first longitudinal axis, and an inlet end adapted for connection to a source of liquid under pressure;
• a first inner housing telescopically mounted within said outer housing for movement between retracted and extended positions, and having a second longitudinal axis coincident with the first longitudinal axis, and an outlet end provided with a first arcuate slot adapted to discharge a stream of liquid under pressure;
• a non-rotatable shaft, one end of said shaft supporting a distributor for rotation thereon downstream of said outlet, and the other end of said shaft mounted in said first inner housing, said distributor being operatively associated with a brake assembly for retarding the rotation of said distributor;
• and
• a nozzle disk rotatably secured to said first inner housing and provided with at least one discharge orifice, and wherein said nozzle is rotatable to align any part of said at least one discharge orifice with said first arcuate slot.

A rotating stream sprinkler comprising:

• a sprinkler body having a discharge nozzle for discharging a stream to atmosphere;
• a distributor assembly having a substantially hollow body portion defining an interior brake chamber, said distributor assembly provided with exterior stream distributing surfaces located downstream of said nozzle, said distributor assembly mounted for rotation on one end of a non-rotating shaft, said one end of said shaft terminating within a closed end of said distributor the other end of said shaft extending out of the distributor assembly in an upstream direction and into said sprinkler body;
• a stator member fixedly secured to said one end of said shaft within said substantially hollow body portion;
• and
• a viscous fluid within said brake chamber for effecting braking action on said distributor assembly upon relative motion between said hollow body portion and said stator member.

A rotating stream sprinkler comprising:

• a sprinkler body having a discharge nozzle adapted to discharge a stream to atmosphere;
• a distributor rotatably mounted on one end of a non-rotating shaft, said one end of said shaft terminating within a closed end of said distributor, the other end of said non-rotating shaft being secured within said sprinkler body such that said discharge nozzle at least partially surrounds said shaft;
• said distributor having a substantially hollow body portion and said one end of said non-rotating shaft having a stationary stator secured thereto within said hollow body portion;
• said hollow body portion having a viscous fluid therein for creating a braking action on said distributor upon relative rotation between said hollow body portion and said stator.

A pop-up, rotating stream sprinkler device comprising:

• an outer housing having a first longitudinal axis, and an inlet end adapted for connection to a source of liquid under pressure;
• a first inner housing telescopically mounted within said outer housing for movement between retracted and extended positions, and having a second longitudinal axis coincident with the first longitudinal axis, and an outlet end adapted to discharge a stream of liquid under pressure to atmosphere;
• a non-rotatable shaft, one end of said shaft supporting a rotary distributor for rotation thereon downstream of said outlet end, and the other end of said shaft mounted in said first inner housing, and wherein said distributor is operatively associated with a brake assembly for retarding rotation of said distributor;
• wherein said rotary distributor is mounted for rotation about said shaft, and is further provided with a plurality of upwardly and outwardly extending grooves arranged relative to said shaft so that liquid under pressure impinging on said surfaces will cause said distributor to rotate about said shaft.
