Abstract
A rotary drive sprinkler having a multiplicity of nozzles which can be changed at any time. The nozzle assembly can have a cylindrical housing having a plurality of nozzles to rotate against a cylindrical housing having at least one stream outlet opening. A nozzle assembly can have a cylindrical cavity at its outer portion receiving a flexible nozzle strip for directing flow from a nozzle housing. A nozzle sleeve, or ring, having a plurality of exit nozzles around the outside of the nozzle assembly can be rotated about an inner housing.
Claims10
A rotary drive sprinkler including a rotatable nozzle housing which comprises:
- an arc control contact member mounted for rotational movement;
- and
- an arc setting adjustor on a top surface of the nozzle housing and which is connected to move in a rotationally opposite direction to the rotational movement of the arc control contact member.
A sprinkler having a reversible drive assembly, comprising:
- a nozzle housing assembly mounted for oscillating rotation and including a setting adjustor for setting or changing a desired arc of oscillation;
- and
- a plurality of settable arc control contacts for driving the nozzle housing assembly through a rotational arc of oscillation as set by the setting adjustor on the nozzle housing assembly, wherein a desired change in the arc of oscillation can be set by rotationally moving the setting adjustor in the same direction as the desired increase or decrease in the arc of oscillation.
A sprinkler comprising:
- a rotationally mounted nozzle housing assembly for distributing water outwardly around the sprinkler;
- a reversing drive assembly for driving the nozzle housing assembly and including a plurality of arc control contact elements which can be variably set at angular positions relative to each other for controlling an arc of oscillation through which the nozzle housing assembly is driven;
- a setting shaft disposed in the nozzle housing assembly for setting the relative angular positions of the arc control contact elements in a reversed angular direction to the rotational direction of the setting shaft to provide user logic during setting in which the setting shaft is turned in the same direction as a desired increase or decrease in the arc of oscillation.
A sprinkler including a rotatably driven nozzle housing assembly, the nozzle housing assembly comprising:
- an arc setting adjustor for setting a selectable arc of oscillation;
- an arc control contact for controlling the arc of oscillation based on a setting of the arc setting adjustor;
- and
- a gear assembly for connecting the arc setting adjustor to the arc control contact such that the arc of oscillation is changed by rotating the arc setting adjustor in the same direction as the desired increase or decrease in arc of oscillation to produce a reverse rotational movement of the arc control contact.
A sprinkler comprising:
- a sprinkler head mounted for rotation through a settable arc of oscillation;
- a reversible drive assembly for alternatingly driving the sprinkler head in opposite directions;
- arc control contact elements for controlling the arc of oscillation of the sprinkler head;
- and
- a movable element on the sprinkler head for reading an arc of oscillation being set such that the arc of oscillation is changed by rotating the movable element in the same direction as the desired increase or decrease in arc of oscillation to produce a reverse rotational movement of the arc control contact elements.
