Abstract
Abstract The invention comprises an assemblage of a wind-sensitive device coupled to responsive power-operated means which in turn are connected to a given deice which requires movement or adjustment dictated by wind direction or wind velocity, or both. In the example given, the invention, as shown in the specification, is shown by way of illustration, as connected to and controlling the nozzle fit of a rotary irrigation sprinkler, with respect to the horizontal, and with respect to the windvelocity and direction, in order automatically to achieve an optimum spray pattern.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
96 words
A wind actuated control device for controlling the angle of pitch of a rotatable irrigation spray nozzle, said nozzle being rotatably tiltably supported and supplied with rotating means and a source of water under pressure, said control device including a supporting frame, wind-sensitive means located thereon mechanically movable in response to wind characteristics consisting of wind velocity and direction from any compass point; and means connecting said wind-sensitive means to said supported tiltable spray nozzle for depressing or elevating the delivery angle of said nozzle during rotation, in accordance with the values of said wind characteristics.
Claim 2
Dependent Claim
96 words
A wind actuated control device for controlling the angle of pitch of a rotatable irrigation spray nozzle, said nozzle being rotatably tiltably supported and supplied with rotating means and a source of water under pressure, said control device including a supporting frame, wind-sensitive means located thereon mechanically movable in response to wind characteristics consisting of wind velocity and direction from any compass point; and means connecting said wind-sensitive means to said supported tiltable spray nozzle for depressing or elevating the delivery angle of said nozzle during rotation, in accordance with the values of said wind characteristics.
Claim 3
Dependent Claim
24 words
The invention according to claim 1, wherein the wind-sensitive means include a pair of rotatable wind vanes set at right angles to one another.
Claim 4
Dependent Claim
27 words
The invention according to claim 2, wherein the said pair of wind vanes are spring-urged to a neutral position in the absence of wind affecting their rotation.
Claim 5
Dependent Claim
67 words
The invention according to claim 1, wherein said means connecting said wind-sensitive means to said support of said spray nozzle include a hydraulic system having a source of fluid under pressure, said system including valve means having fluid connections to cylinders connected to said spray nozzle support, with piston means in said cylinders for altering the tilt of said spray support in response to said wind characteristics.
Claim 6
Dependent Claim
147 words
The invention according to claim 1, wherein the wind-sensitive means includes a pair of wind vanes rotatively mounted at right angles on a support by staffs spring-urged to a neutral position in the absence of wind affecting either of them, the staffs being each in turn connected to an hydraulic system including a servo-valve, each servo-valve being furnished with fluid under pressure, and being adjusted to supply a fluid flow in response to the movement of its connected vane staff; a pair of hydraulic cylinders containing pistons connected at right angles to the tiltable support of said rotary spray nozzle; a pair of fluid lines leading from each valve to the opposite ends of said hydraulic cylinders; and mechanical means connected between the wind vane staffs and the tiltable support of said nozzle checking the fluid line flow to said cylinders in response to said wind characteristics.
Claim 7
Independent Claim
137 words
The method of regulating the pitch of a rotary-powered irrigation spray nozzle with respect to wind velocity and intensity, wherein the method steps consist of: mounting said nozzle for rotary motion in such manner that its angle with respect to its horizontal mounting may be varied at any point during its cycle of rotation; providing wind responsive means for detection of wind characteristics; mounting said wind-responsive means in a manner to detect said characteristics consisting of wind direction and velocity from any compass point; and connecting said wind responsive means with said nozzle mounting and said nozzle automatically to counteract by depressing said nozzle to a selected degree and to elevate said nozzle to a selected degree with respect to upwind and down-wind movements and force of said wind direction, thereby to provide an optimum irrigation pattern.
Claim 8
Independent Claim
137 words
The method of regulating the pitch of a rotary-powered irrigation spray nozzle with respect to wind velocity and intensity, wherein the method steps consist of: mounting said nozzle for rotary motion in such manner that its angle with respect to its horizontal mounting may be varied at any point during its cycle of rotation; providing wind responsive means for detection of wind characteristics; mounting said wind-responsive means in a manner to detect said characteristics consisting of wind direction and velocity from any compass point; and connecting said wind responsive means with said nozzle mounting and said nozzle automatically to counteract by depressing said nozzle to a selected degree and to elevate said nozzle to a selected degree with respect to upwind and down-wind movements and force of said wind direction, thereby to provide an optimum irrigation pattern.
