  • Rotary sprinkler head having individually-adjustable deflector plates for watering irregularly-shaped areas
    Patent number: 5267689
    Abstract: A deflector cap for use in connection with a conventional pop-up or other type of rotary sprinkler head is held in a fixed angular position with respect to the sprinkler head housing by means of a downwardly extending rod that slides within a tube fixedly attached to the sprinkler head housing. An annular array of individually-adjustable, wedge-shaped, flat deflector plates is mounted to the underside of the deflector cap. Each of the deflector plates is formed to have an outer wide end and an inner narrow end. The inner end of each of the deflector plates is hingedly attached to the deflector cap at a uniform radial distance from the center of the deflector cap, thereby permitting vertical movement of the outer ends of each of the deflector plates. Vertical movement of the individual deflector plates is facilitated by a screw adjustment mechanism associated with each of the deflector plates.
