Claim 4

A system as defined in claim 1 in which said means for oscillating includes: a cable coupled to each of the arms of a group; means for applying a tension load at one end of said cable; and means for cyclically pulling at the other end of said cable.

Claim 5

A system as defined in claim 3 in which each of said arms is carried on a pivoting shaft and in which said cable is coupled to each arm at said shaft.

Claim 6

A system as defined in claim 3 in which said cable is coupled to each arm at a point spaced from the pivot point of the arm.

Claim 7

A system as defined in claim 3 in which said means for cyclically pulling comprises the carriage drive motor.

Claim 8

A system as defined in claim 6 including a member driven in rotation by said carriage drive motor and means for coupling said cable to said member.

Claim 9

In a self-propelled sprinkling irrigation system having a high capacity irrigation pipeline supported on a plurality of spaced motor driven carriages with an electrical switch at a carriage for energizing the carriage drive motor as a function of carriage position, a low capacity spraying system for insectides, herbicides, fertilizer and the like, comprising in combination: a low capacity pipeline supported at said high capacity pipeline; means for supplying a fluid under pressure to said low capacity line; a plurality of arms spaced along and pivotally supported at said high capacity line, with a spraying nozzle on each of said arms and with a group of arms associated with a carriage and drive motor; a solenoid actuated control valve for each of said arms; conduit means connecting each of said valves between said low capacity line and the corresponding nozzle; and means for oscillating a group of said arms and actuating the valve solenoids thereof to spray fluid when the associated drive motor is energized by the switch to move the carriage.

Claim 10

In a self-propelled sprinkling irrigation system having a high capacity irrigation pipeline supported on a plurality of spaced motor driven carriages with an electrical switch at a carriage for energizing the carriage drive motor as a function of carriage position, a low capacity spraying system for insectides, herbicides, fertilizer and the like, comprising in combination: a low capacity pipeline supported at said high capacity pipeline; means for supplying a fluid under pressure to said low capacity line; a plurality of arms spaced along and pivotally supported at said high capacity line, with a spraying nozzle on each of said arms and with a group of arms associated with a carriage and drive motor; a solenoid actuated control valve for each of said arms; conduit means connecting each of said valves between said low capacity line and the corresponding nozzle; and means for oscillating a group of said arms and actuating the valve solenoids thereof to spray fluid when the associated drive motor is energized by the switch to move the carriage.

Claim 11

A system as defined in claim 8 in which said means for oscillating includes: a cable coupled to each of the arms of a group; means for applying a tension load at one end of said cable; and means for coupling the other end of said cable to the carriage drive motor for cyclically pulling said cable as said motor rotates.

Claim 12

In a self-propelled sprinkling irrigation system having a high capacity irrigation pipeline supported on a plurality of spaced motor driven carriages and control means for energizing the drive motors, a low capacity spraying system for insectides, herbicides, fertilizer and the like, comprising in combination: a low capacity pipeline supported at said high capaciTy pipeline; means for supplying a fluid under pressure to said low capacity line; a plurality of spray stations carried on said high capacity line at spaced intervals, each of said stations including a pivotally mounted arm with a nozzle, a control valve and a conduit means connecting each of said valves between said low capacity line and the corresponding nozzle; and means for oscillating a group of said arms and actuating the control valves thereof as a drive motor is energized to spray fluid as a carriage moves.

Claim 13

In a self-propelled sprinkling irrigation system having a high capacity irrigation pipeline supported on a plurality of spaced motor driven carriages and control means for energizing the drive motors, a low capacity spraying system for insectides, herbicides, fertilizer and the like, comprising in combination: a low capacity pipeline supported at said high capaciTy pipeline; means for supplying a fluid under pressure to said low capacity line; a plurality of spray stations carried on said high capacity line at spaced intervals, each of said stations including a pivotally mounted arm with a nozzle, a control valve and a conduit means connecting each of said valves between said low capacity line and the corresponding nozzle; and means for oscillating a group of said arms and actuating the control valves thereof as a drive motor is energized to spray fluid as a carriage moves.

Claim 14

A system as defined in claim 10 in which a group of arms on a portion of the high capacity line are oscillated by the drive motor of the carriage which moves said portion of the high capacity line.

Claim 15

A system as defined in claim 11 in which said means for oscillating includes: a cable coupled to each of the arms of a group; means for applying a tension load at one end of said cable; and means for coupling the carriage drive motor to the other end of said cable for cyclically pulling said cable.
