Weighted sprinkler head apparatus
The present invention relates to an irrigation sprinkler head having a removable weighted collar thereon. The sprinkler head has a tapered water inlet for wedging a weighted collar having a matching tapered opening therethrough.
1. A sprinkler head having a removable weighted collar comprising:
a sprinkler head body having an upper body portion having an elongated tapered water inlet having a water passageway therethrough, said upper body portion having a nozzle for directing water from said elongated tapered water inlet, and said sprinkler head body having a lower body portion; and
said weighted collar having a tapered bore therethrough, said tapered bore being sized to fit over said elongated tapered water inlet and to wedge thereto by the weight of said weighted collar, said weighted collar having a hollow interior filled with a fluid material;
whereby said weighted collar is prevented from moving relative to said elongated tapered water inlet of said sprinkler head body with vibration and movement of said sprinkler head.
2. The sprinkler head in accordance with claim 1 in which said fluid material is a granular material.
3. The sprinkler head in accordance with claim 1 in which said hollow interior weight is filled with said fluid material comprising granular magnetite.
4. The sprinkler head in accordance with claim 3 in which said elongated tapered water inlet has a means for attaching to a water supply pipe.
5. The sprinkler head in accordance with claim 4 in which said tapered bore of said weighted collar is sized to ride on said elongated tapered water inlet to thereby allow a continuing wedging thereon from the vibration of said sprinkler head.
6. The sprinkler head in accordance with claim 5 in which said elongated tapered water inlet is removably attached to said sprinkler body.
7. The sprinkler head in accordance with claim 6 in which said elongated tapered water inlet is removably attached to said sprinkler body with a threaded attachment.
