Patent number: 4265403Abstract: A lawn sprinkler system has a plurality of sprinkler heads connected to a common water supply line. The sprinkling or irrigation, the rate of rotation and the contour of the area sprinkled all are controlled at each sprinkler head. A timer valve associated with a manually adjustable control setting regulates the sprinkling cycle at each head in response to rotation of the head, following which water is bypassed to the next sprinkler head in succession. Further, each sprinkler head contains a rotatable nozzle assembly which is adjustable to provide a spray pattern which will conform to different contours or areas to be sprinkled by each head independently of the other heads in the line in such a way as to afford the greatest possible water efficiency.Type: GrantFiled: May 9, 1979Date of Patent: May 5, 1981Assignee: Advanced Products Development CorporationInventor: Ralph A.

Patent number: 4019686Abstract: A sprinkler for watering an area having a specific shape using water subject to an intermittent and regular variation in pressure introduced against a patterned plate positioned in the base of the sprinkler. The plate is situated adjacent to a slotted opening in the lower solid side of a hollow head moveable under water pressure within a cavity formed between the base and a cap of the sprinkler. A nozzle is attached to the upper end of the head to distribute the water passing the restricting window and segment of pattern disposed in its path in the base. Springs are associated with the head to provide a torque to the sprinkler head as the head rises in the cavity under pressure of the water on the lower side of the head. A gear and ratchet is provided on the head to prevent the head from returning to the first position upon reduction of the water pressure and resultant reaction of the springs to return the head to its position of rest within the cavity.Type: GrantFiled: May 27, 1975Date of Patent: April 26, 1977Inventor: Florencio Neto Palma
