ABSTRACT:
A frost clip is provided for a rotary sprinkler of the type which includes a sprinkler body, a nozzle for emitting a stream and a rotatable distributor plate adapted to receive and redirect the stream. The frost clip is attachable to the sprinkler body so as to be intermittently engaged by the stream as the distributor plate rotates about its axis of rotation. The frost clip is formed with a channel facing radially towards and extending substantially parallel to an axis of rotation of the rotor plate. The channel is constructed and arranged to intermittently deflect the stream back toward the rotor plate and at least a portion of the sprinkler body as the stream rotates past the clip, to thereby inhibit ice buildup on the rotor plate and adjacent sprinkler body portions.
