ABSTRACT:
A sprinkler unit of the type that includes an impact drive sprinkler vertically reciprocable inside a subterranean can or case is modified to incorporate a modern pop-up rotor-type sprinkler. The rotor-type sprinkler has a lower retraction spring retainer half-way up its outer riser and a shortened retraction spring. A cylindrical adaptor sleeve surrounds the riser and has its upper end screwed into the upper end cap of the rotor-type sprinkler. The impact drive sprinkler and its attached riser assembly are unscrewed from the subterranean mounting case. Thereafter, a lower male threaded end of the adaptor sleeve is screwed into a female threaded segment at the junction of the lower and upper sections of the cylindrical mounting case. A ring-shaped protective cover plate with a pair of spring retention arms is rotatably mounted to the top end of the rotor-type sprinkler to fill the gap between the sprinkler and the upper curved lip of the cylindrical mounting case.
