Linear moving irrigating apparatus

An irrigating mover apparatus for linear movement along a field between opposite length portions thereof having a wheeled frame, and a water-carrying revolving axial shaft that mounts wheel means on the frame, the improvement which comprises:

• reciprocating hydraulic jack means operatively mounted on the frame, a bull gear operatively mounted on the shaft for advancing the mover unit along the field, a water line operatively connected to said jack means for supplying the water under pressure thereto for actuating it, means in said water line for controlling the operation of said hydraulic jack means, a stroking arm operatively connected to said jack means, and cooperating with said bull gear for rotating said gear, control valve means for applying water under positive pressure to said jack means for reciprocating it positively under water pressure forwardly and backwardly on the frame in such a manner as to actuate said bull gear on its forwawrd stroke, valve means cooperating with movement of said jack means for reversing the flow of water to and from said jack means to effect its reciprocating movement, and additional valve means controlled by torque resistance to movement of said jack means that is actuated to cut-off flow of water under pressure to said jack means when resistance to advancing movement of the mover apparatus approaches a pre-selected value.

An irrigating mover apparatus for linear movement along the field between opposite length portions thereof, having a wheeled frame and a water-carrying revolving axial shaft that mounts at least one wheel of the frame, having water spray means connected to the axial shaft for receiving water therefrom and dispersing it on the field, and also having a bull gear mounted on the axial shaft for rotating movement to advance the mover apparatus along the field, the improvement which comprises:

• a hydraulic jack operatively mounted on the frame, a stroking arm operatively connected to said jack for actuating thereby, said stroking arm having means for engaging teeth of the bull gear for rotating it to advance the mover apparatus along the field, means for supplying water under pressure to the axial shaft and to the water spray means connected thereto, means operatively associated with said jack and sensitive to torque resistance encountered by said jack in advancing the mover apparatus, said last-mentioned means being adapted to positively shut-off supply of water to said jack and to said axial shaft when a pre-selected torque resistance is encountered by said jack.

An irrigating mover apparatus for linear movement along a field between opposite length portions thereof having a wheeled frame and a water-carrying revolving axle shaft that mounts at least one wheel of the frame, the improvement which comprises:

• a bull gear secured on the shaft for rotating it to advance the apparatus along the field, a hydraulic jack operatively mounted on the frame, a stroking arm at one end operatively connected to said jack for actuation thereby, teeth-engaging means operatively carried on said stroking arm and adapted to engage teeth of said bull gear for rotating it, means for supplying water under positive pressure to actuate said jack for advancing the unit along the field, a pivotally mounted fulcrum arm secured to said jack for movement therewith, pressure cut-off means operated by said fulcrum arm and cooperating with said water supplying means for limiting the maximum torque exerted by said jack in advancing the apparatus, said fulcrum arm being connected to a lower end of said jack and pivoted on the wheeled frame, and said fulcrum arm having an extending end operatively connected to said last-mentioned means for moving said last-mentioned means to a closed position when the selected torque resistance is encountered by said jack during its movement.

A self-propelled irrigating mover apparatus for linear movement along a field between opposite length portions thereof having a wheeled frame and a water-carrying revolving axial shaft that mounts wheel means on the frame, the improvement which comprises:

• a bull gear mounted on the frame for rotating movement to advance the mover apparatus along the field, a hydraulic jack operatively mounted on the frame, a stroking arm operatively connected to said jack for actuation thereby, said stroking arm having means for operatively engaging teeth of said bull gear for rotating it to advance the mover apparatus along the field, means for supplying water under positive fluid pressure to actuate said jack, adjustment means cooperating with said teeth engaging means for selecting the number of teeth engaged thereby to control the speed of forward movement of the apparatus, valve means connected to said water supply means for alternately applying energizing water to opposite ends of said jack to positively effect reciprocating action thereof under water pressure, and additional valve means controlled by torque resistance to forward advance of the mover apparatus along the field for positively cutting off the supply of positive fluid pressure to said jack and de-energizing it.

A self-propelled irrigating mover apparatus for movement along a field between opposite length portions thereof having a wheeled frame and sprinkler means, the improvement which comprises, a hydraulic jack operatively mounted on the wheeled frame and having stroking arm means actuated thereby to advance the frame along the field, means for supplying water under positive fluid pressure to said jack, valve means connected between said water supplying means and said jack for actuating said jack under water pressure to forwardly advance the mover apparatus along the field, and additional valve means controlled by torque resistance to the forward advance of the mover apparatus along the field as applied to said stroking arm for positively cutting-off the supply of positive fluid pressure to said jack and de-energizing it.
