Mobile irrigation system

Claim 2

An improved, mobile irrigating system of the type having a plurality of wheel mounted irrigating pipes coupled in line to a central, internal combustion engine powered unit which turns the irrigating pipe wheels by turning the line of coupled pipes wherein the improvement comprises a sealed, hollow cross support structure for the central powEr unit, the hollow space of the cross support constituting a fuel tank for the engine, and indicator means mounted on selected ones of the wheels and aligned with each other to indicate the rotational orientations of the pipes about their longitudinal axes.

Claim 3

An improved, mobile irrigating system as recited in claim 1 wherein a hollow, T-shaped pipe is mounted within the hollow cross support, a hollow fitting passes into the hollow of the cross support and is sealed to the midpoint of the T-shaped pipe to establish fluid communication therebetween, the distal ends of the T-shaped pipe being positioned within the ends of the hollow cross support, and check valve means mounted within the distal ends of the T-shaped pipe, whereby fuel within the hollow cross support may be sucked through the T-shaped pipe by the engine regardless of the attitude of the cross support with respect to gravitational forces which might cause the fuel within the cross support to accumulate at one end.

Claim 4

An improved, mobile irrigating system as recited in claim 2 wherein the central power unit comprises a pair of opposed, parallel axles and the cross support is elongated and rigidly connected between the pair of axles.

Claim 5

An improved, mobile irrigating system as recited in claim 2 wherein the hollow of the cross support is sufficiently large to accommodate a season''s supply of fuel for an internal combustion engine.

Claim 6

An improved, mobile irrigating system as recited in claim 1 wherein the indicator means comprise a plurality of sector shaped panels, each panel being attached to a separate wheel and laying flat in the plane of the wheel and each panel having a figure graphically depicted thereon, the figure having a major point extending radially outwardly from the longitudinal axes of the pipe.

Claim 7

An improved, mobile irrigating system as recited in claim 5 wherein at least one pipe has at least one sprinkler head mounted thereon and an indicating panel is attached to the wheel mounted on the one pipe with the major point of the figure being aligned with the sprinkler head.
