Abstract
Abstract A composite, mobile, laterally moving sprinkling pipeline so arranged and controlled that each end of the composite line alternately can be caused to travel a predetermined distance along an arcuate path with the opposite end of the composite line temporarily being substantially at the center of curvature of such arcuate path and with the entire line thus swinging forwardly in alternate angular direction, the composite pipeline being flexible and comprising connected sections with each section automatically moving to maintain alignment with an adjacent section during line travel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
In a moving irrigation system, a flexible sprinkling pipeline, traveling supports for said pipeline positioned near each end of said pipeline and at intervals therebetween, operating means for each of said traveling supports, control means for the operating means for each of the end traveling supports so arranged that each of said end traveling supports will be operated to cause one end of said pipeline alternately to move ahead a predetermined distance further than the other end of said pipeline, and means controlling the operation of the intervening traveling supports acting to cause said intervening traveling supports to bring the intervening portions of said pipeline into alignment with the end portions of said pipeline, whereby said pipeline when moving over the ground will swing forwardly in alternate angular direction.
Claim 2
Dependent Claim
86 words
The combination set forth in claim 2 with the sections of said flexible pipeline extending between said traveling supports capable of being moved into angularity with each other, with said operating means for each of said traveling supports including a motor, and with the operation of said motors in said intervening traveling supports occasioned by the movement of the section of said pipeline at one side of the traveling support into angularity with the section of said pipeline at the other side of said traveling support.
Claim 3
Dependent Claim
54 words
The combination set forth in claim 2 with said operating means for each of said traveling supports including a motor, with the control means for said end traveling supports including a switch in the circuit to the motor in each of said end traveling supports, and means for automatically and alternately operating said switches.
Claim 4
Dependent Claim
133 words
The combination set forth in claim 4 with the addition of a guide element near one end of said pipeline extending along in the direction of travel desired for said pipeline, said means for operating said switches including means sensitive to the angularity between said pipeline and said guide and so arranged that when said pipeline moves in one direction into a predetermined angularity with said guide, one of said switches will be operated and when said pipeline moves to the same angularity with said guide in the alternate direction the other of said switches will be operated, whereby the operation of said switches, resulting in alternate operation of the motors in the traveling supports at the ends of said moving pipeline, will automatically cause said pipeline to swing in alternate angular direction.
