Abstract
Abstract An automatic intermittent break-up device repeatedly movable toward the center of the fluid stream exiting a nozzle to a first position to increase the break-up of the stream and movable away from the center of the fluid stream exiting the nozzle to a second position to decrease the break-up. The increased break-up sequence of operation provides a more desired distribution of fluid on the surface area. The intermittent break-up device includes an adjustable break-up member or screw. The member is connected to an automatic mechanism of an irrigation device to drive the member into the first position when the irrigation device delivers fluid over a particular area of the ground and drives the member into the second position when the irrigation device subsequently delivers fluid over the said particular area of the ground.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
An automatic intermittent stream break-up means for an irrigation device with an exit nozzle comprising: a break-up member connected to the irrigation device, said break-up member movable into a first position placing at least a portion of the break-up member in the path of the fluid stream that exits the nozzle thereby causing continuous breakup of the fluid stream of the irrigation device when the fluid stream sweeps a distribution area, said break-up member movable into a second position such that the break-up member causes less continuous break up of the fluid stream that exits the nozzle of the irrigation device when the fluid stream sweeps the distribution area, and an automatic mechanism connected to the break-up member for moving the break-up member from said first position to said second position.
Claim 2
Dependent Claim
131 words
An automatic intermittent stream break-up means for an irrigation device with an exit nozzle comprising: a break-up member connected to the irrigation device, said break-up member movable into a first position placing at least a portion of the break-up member in the path of the fluid stream that exits the nozzle thereby causing continuous breakup of the fluid stream of the irrigation device when the fluid stream sweeps a distribution area, said break-up member movable into a second position such that the break-up member causes less continuous break up of the fluid stream that exits the nozzle of the irrigation device when the fluid stream sweeps the distribution area, and an automatic mechanism connected to the break-up member for moving the break-up member from said first position to said second position.
Claim 3
Dependent Claim
37 words
An automatic intermittent stream break-up device for an irrigation device with an exit nozzle, as set forth in claim 1 wherein, said automatic mechanism alternately moves the break-up member from said first position to said second position.
Claim 4
Dependent Claim
39 words
An automatic intermittent stream break-up device for an irrigation device with an exit nozzle, as set forth in claim 2 wherein, said automatic mechanism alternately and repetitively moves the break-up member from said first position to said second position.
Claim 5
Dependent Claim
29 words
An automatic intermittent stream break-up device for an irrigation device with an exit nozzle, as set forth in claim 2 including, an oscillating irrigation device including an oscillating nozzle.
Claim 6
Dependent Claim
53 words
An automatic intermittent stream break-up device for an irrigation device with an exit nozzle, as set forth in claim 4 wherein, said irrigation device including a reversing mechanism, said break-up member connected to said oscillating nozzle and, said automatic mechanism connected to said reversing mechanism to change the position of said break-up member.
Claim 7
Dependent Claim
29 words
An automatic intermittent stream break-up device for an irrigation device with an exit nozzle, as set forth in claim 2 including, a rotating irrigation device with a turbine drive.
Claim 8
Dependent Claim
50 words
An automatic intermittent stream break-up device for an irrigation device with an exit nozzle, as set forth in claim 6 wherein, said break-up member connected to said turbine drive in said irrigation device, and said automatic mechanism connected to said turbine drive to change the position of said break-up member.
