Adjustable arc fixed spray sprinkler nozzle
First Claim
1. An adjustable arc fixed spray sprinkler nozzle, which comprises:
- a nozzle body having a top and sides with the nozzle body having an axis;
a plurality of water discharge slots provided in the sides of the nozzle body with the slots pointing outwardly relative to the axis of the nozzle body such that water is discharged to the sides of the nozzle body through the slots, wherein each slot is horizontal and extends around only a portion of the nozzle body; and
a plurality of rotatable skirts carried on the nozzle body extending parallel to the axis of the nozzle body with one skirt being in abutment with each water discharge slot, each skirt being progressively rotatable from a first position in which the skirt imposes minimum interference with the water discharge slot to a second position in which the skirt imposes maximum interference with the water discharge slot, whereby the arc coverage provided by the water flow through the water discharge slots is controlled by the position of the skirt for each slot.

Abstract
A fixed spray sprinkler nozzle has adjustable arc coverage. The nozzle has a nozzle body with sideward facing water discharge slots including a bottom slot and a top slot. Flow blocking skirts control the open length of each of the slots. The bottom slot is fixed on the nozzle body, but the top slot is rotatable on the nozzle body, in concert with the opening or unblocking of the bottom slot'"'"'s length, from a position overlying the bottom slot to a position directed in an opposite direction from the bottom slot. When the bottom slot is fully open, the top slot may then be progressively opened over its entire length. Thus, the arc coverage can be infinitely adjusted over the combined circumferential length of both the bottom and top slots together. The slots have a grooved bottom wall to provide smooth water flow and good pattern definition at each side of the selected arc.

3. An adjustable arc fixed spray sprinkler nozzle, which comprises:
-
a nozzle body having at least two, sideward facing water discharge slots provided in the nozzle body; and wherein at least one water discharge slot is fixed relative to the nozzle body and at least one water discharge slot is rotatable relative to the nozzle body from a first position in which the rotatable water discharge slot at least partially overlies the fixed water discharge slot to a second position in which the rotatable water discharge slot has been rotated out of its overlying position and is oriented in a different direction from the fixed water discharge slot.

4. An adjustable arc fixed spray sprinkler nozzle, which comprises:
-
a nozzle body having a top and sides; at least two water discharge slots in the sides of the nozzle body; at least two flow blocking members movably carried on the nozzle body, wherein one flow blocking member is associated with each of the slots for adjustably blocking the slot'"'"'s length to thereby control the arc coverage provided by the slot; and a single, user operable adjustment member movably carried on the nozzle body for moving both flow blocking members relative to their associated slots. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. An adjustable arc fixed spray sprinkler nozzle, which comprises:
-
a nozzle body having a top and sides; at least one water discharge slot provided somewhere in the sides of the nozzle body which slot is adjustable in length to thereby control the arc coverage provided by the slot; and a rotatable adjustment ring that forms an exterior portion of the top of the nozzle body with the adjustment ring rotating around a fixed interior portion of the top of the nozzle body, wherein the adjustment ring is sized to be gripped and turned by hand, the adjustment ring when so turned adjusting the length of the water discharge slot to change the arc coverage, and wherein the adjustment ring is located above the water discharge slot. - View Dependent Claims (14, 15, 16, 17, 18)
