Oscillating lawn sprinkler
First Claim
1. In an oscillating sprinkler comprising a bearing block, a watering pipe having a water inlet opening and spray nozzles and pivotally mounted on said bearing block so that it is capable of oscillating around a longitudinal axis, a water pressure actuated driving mechanism housed in a watertight box connected to a first end of said watering pipe and to be connected to a water supply source for driving said watering pipe oscillatingly about said axis according to an angle and a water flow rate adjustable by an adjustment means associated with said driving mechanism box, a choking device to selectively limit the watering range of said sprinkler, said choking device being housed in a movable manner within a second end of said watering pipe for cooperation with said water inlet opening, the improvement comprising:
- said choking device including a control means having a cross-sectional size which is smaller than the inner bore of said watering pipe, such that water from said water inlet opening is flowable between said watering pipe and said control means;
external manual-actuation means connected to said control means and having sealing means for sealing with said watering pipe;
internal flow-diverting means connected to said control means and having sealing means for sealing with said watering pipe; and
said flow-diverting means being movable to appropriate positions, in response to corresponding angular displacements of said control means by said external manual-actuation means, to divert the flow of water coming from said opening in such a way as to deliver it either to all of said spray nozzles of said watering pipe or to only parts of said spray nozzles located along length portions of said watering pipe on opposite sides of said flow-diverting means.

Abstract
An oscillating lawn sprinkler includes a watering pipe provided with spray nozzles and a choking device for selectively limiting the watering range of the sprinkler. The choking device includes a control member, an external manual-actuation device and an internal flow-diverting element. The internal flow-diverting element is capable of being oriented, through angular displacements of the control device, in corresponding positions for diverting the flow of water coming from a water inlet opening in such a manner as to deliver the water to all of the spray nozzles in the watering pipe, or to parts of the nozzles provided in opposite length portions of the watering pipe located on opposite sides of the flow-diverting element.

8. An assembly for use in an oscillating water sprinkler, said assembly comprising:
-
a longitudinal watering pipe adapted to be mounted for oscillation on a bearing block of a water sprinkler, said watering pipe having an inner bore defining an interior and a water inlet opening for the introduction of water into said interior of said water pipe, and said watering pipe having spaced longitudinally thereof a plurality of nozzles for spraying water from said interior; control means extending into an end of said watering pipe and housed in said interior, said control means having a cross-sectional size smaller than said inner bore of said watering pipe, such that water from said water inlet opening is flowable between said watering pipe and said control means; external manual-actuation means connected to said control means for rotating said control means relative to said water pipe and having sealing means for sealing with said watering pipe; and internal flow-diverting means, connected to said control means and having sealing means for sealing with said watering pipe, for, upon corresponding angular displacement of said control means by said manual-actuation means, moving relative to said inlet opening to respective positions to allow delivery of water to all of said nozzles or to only parts of said nozzles located along length portions of said watering pipe on opposite sides of said flow-diverting means. - View Dependent Claims (9, 10, 11, 12, 13, 14)
