Abstract:
A sprinkler head, comprising:(a) a hollow housing adapted for connection to an irrigation system; (b) a cap threadably engaged at a top end of said housing and having a central channel; (c) a hollow riser slidably contained within said housing; (d) a nozzle adapted for connection to one end of said riser for emitting irrigation water; (e) a compression spring riding on said riser and engaging said housing for maintaining said riser in a normally retracted position; and (f) a signaling mechanism enclosed within said riser, said signaling mechanism including a plurality of telescoping sleeves adapted for upward telescoping extension; whereby when said nozzle is partially or completely dislocated, water pressure causes said signaling mechanism to extend upward to indicate said damage or dislocation.
