Sprinkler head location indicator

Abstract

The sprinkler head location indicator is a shallow dish adapted for placement on the shaft of a pop-up sprinkler head. The dish is concave upward and has a small pilot hole formed through its center. A plurality of radially extending guidelines is formed on the bottom surface of the dish, the guidelines having hash marks at uniform intervals to form scale markings. The guidelines are severed radially to a uniform length forming flexible segments and the dish is pushed up the shaft to the ground flange of the sprinkler head. The flexible segments bend against the sprinkler head shaft, thereby retaining the dish on the shaft.

1 . A sprinkler head location indicator, comprising a shallow dish, the dish having:
 an upper face and a lower face;   a pilot hole extending through a center of the dish;   a plurality of radially-extending guidelines defined on the lower face thereof, and   a plurality of hash marks defined at intervals on the guidelines to form scale markings for severing the guidelines to uniform length.   
   
   
       2 . The sprinkler head location indicator according to  claim 1 , wherein said upper face is concave. 
   
   
       3 . The sprinkler head location indicator according to  claim 1 , wherein said lower face is convex. 
   
   
       4 . The sprinkler head location indicator according to  claim 1  wherein said guidelines extend radially from said pilot hole. 
   
   
       5 . The sprinkler head location indicator according to  claim 1 , wherein said shallow dish is fabricated from a flexible and resilient material. 
   
   
       6 . A sprinkler head location indicator, comprising a shallow dish having:
 an upper concave face and a lower convex face;   a pilot hole extending through a center of the dish;   a plurality of radially-extending guidelines defined on the lower convex face thereof, and   a plurality of hash marks defined at intervals on the guidelines to form scale markings for severing the guidelines to uniform length.   
   
   
       7 . The sprinkler head location indicator according to  claim 6  wherein said guidelines extend radially from said pilot hole. 
   
   
       8 . The sprinkler head location indicator according to  claim 6 , wherein said shallow dish is fabricated from a flexible and resilient material. 
   
   
       9 . A sprinkler head location indicator, comprising a shallow dish fabricated from flexible and resilient material, said dish having:
 an upper concave face and a lower convex face;   a pilot hole extending through a center of the dish;   a plurality of radially-extending guidelines defined on the lower convex face thereof, said guidelines, when severed, defining retaining tabs for retaining said dish on a shaft of a pop-up sprinkler head; and   a plurality of hash marks defined at intervals on the guidelines to form scale markings for severing the guidelines to uniform length.   
   
   
       10 . The sprinkler head location indicator according to  claim 9  wherein said guidelines extend radially from said pilot hole.
