US 4,376,513 A · Irrigation stream splitter

In a sprinkler head having a vertically disposed cylindrical body adapted for attachment to a source of irrigation fluid under pressure and a nozzle portion extending vertically longitudinally from the body and concentric therewith for continuous rotation to create a horizontal spray pattern over a circular area with water emitted as a stream from a nozzle opening in the nozzle portion, the attachment for splitting the stream which would otherwise strike the trunks of the trees when the sprinkler head is disposed between a plurality of trees to irrigate them to, thereby, prevent trunk rot, said attachment comprising:

(a) a first cylindrical collar adapted to be disposed concentrically about the cylindrical body, said first collar having gripping means on the inner surface thereof for gripping the cylindrical body when disposed concentrically thereabout an amount sufficient to hold said collar from moving out of position from the operational vibrations of the sprinkler head while allowing said collar to be manually rotated into a desired position;
(b) a first wedge-shaped fin member carried by said first collar on one end and disposed vertically close adjacent the nozzle portion with the narrow edge of the wedge facing the nozzle opening when the nozzle opening, a first tree, and said first fin member are in radial alignment whereby the emitted stream of fluid would strike the first tree trunk is split by said first fin member and the fluid thereof is directed to the area beside said first tree;
(c) a second cylindrical collar adapted to be concentrically disposed about said first cylindrical collar, said second cylindrical collar having gripping means on the inner surface thereof for gripping said first cylindrical collar when disposed concentrically thereabout an amount sufficient to hold said second collar from moving out of position with respect to said first collar from the operational vibrations of the sprinkler head while allowing said second collar to be manually rotated with respect to said first collar into a desired position;
and,
(d) a second wedge-shaped fin member carried by said second collar on one end and disposed vertically close adjacent the nozzle portion with the narrow edge of the wedge facing the nozzle opening when the nozzle opening, a second tree, and said second fin member are in radial alignment whereby the emitted stream of fluid which would strike the trunk of said second tree is split by said second fin member and the fluid thereof is directed to the area beside said second tree.

In a sprinkler head having a vertically disposed cylindrical body suited for attachment to a source of fluid under pressure and a nozzle portion extending vertically longitudinally from the body and concentric therewith for rotation to create a horizontal spray pattern over a circular arc with fluid emitted as a stream from a nozzle opening in the nozzle portion, an improvement for preventing a direct wetting of the trunks of trees located within the spray pattern comprising:

(a) a first cylindrical collar suited to be concentrically disposed about the cylindrical body;
(b) a first wedge-shaped fin member carrier by said first collar on one end and disposed vertically close adjacent the nozzle portion with the narrow edge of the wedge facing the nozzle opening when the nozzle opening, a first tree, and said first fin member are in radial alignment whereby the emitted stream of fluid which would strike the tree trunk is split by said first fin member and the fluid thereof is directed to the area beside the first tree;
(c) a second cylindrical collar suited to be concentrically disposed about said first collar;
and
(d) a second wedge-shaped fin member carried by said second collar on one end and disposed vertically close adjacent the nozzle portion with the narrow edge of the wedge facing the nozzle opening when the nozzle opening, a second tree, and said second fin member are in radial alignment.
