Abstract
Abstract A self-propelled irrigation apparatus wherein a rigid waterdistributor pipe is revolved about one of its ends as a pivot which also provides a connection to the water source, the distributor pipe being conveyed over the ground to be sprayed by individual electric motor-powered mobile supports. The pipe sections between mobile supports are strengthened by trussing with cables located beneath the level of the pipe and the individual motors driving the multiple support assemblies are controlled in response to horizontal flexing of the distributor pipe due to lagging or advancing of any one of the support assemblies relative to the others. Each support assembly constitutes a rigid A-frame structure with two pivotally-mounted and independently driven ground-wheel units located on opposite sides of the distributor pipe. The drive means for the support assemblies are sychronized so as to drive the respective support assemblies at the proper speed to make one revolution of the distributor pipe in a given time interval.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
In a self-propelled irrigation device having a continuous rigid water-distributor pipe carried by a plurality of spaced mobile support assemblies, deflection sensor means for detecting bending of said pipe at the support assemblies to control the operation of the assemblies comprising; a rigid frame member fixed to the support assembly and located beneath the pipe extending parallel therewith, a sensor arm, first clamping means clamping one end of the arm to the pipe and in pivotal relation to said frame member, the other end of said sensor arm being free, second clamping means for mounting control switches to the pipe and in pivotal relation to said support structure adjacent the free end of the sensor arm, and contact members on the free end of said sensor arm for contacting selected ones of said switches upon deflection of the pipe between the clamping means.

Claim 3
Dependent Claim
167 words
A mobile support assembly for carrying a movable water-distributor pipe comprising; a rigid frame structure adapted for connection to a distributor pipe and including a frame member extending at right angles to the distributor pipe, a source of motive power on said frame structure, first and second ground-wheel units pivotally mounted for swing movement relative to the frame member on the opposite end portions of said frame member, each ground-wheel unit including a wheel frame having two spaced ground-wheels journal for rotation thereon, said wheel frame being pivotally mounted on the frame member for swing movement relative to said frame member, a stub shaft on said wheel frame extending coaxial with the pivotal connection of the wheel frame, drive transfer means independently drivingly connecting the ground-wheel of each of said ground-wheel units to said power source, said drive transfer means including a first drive connection between the motive power source and said stub axle and second and third drive connections between the stub axle and said ground-wheels.
Claim 4
Dependent Claim
167 words
