Abstract
Abstract An elongated boom having a plurality of sprinkler heads mounted thereon with the boom being constructed of a plurality of articulately connected sections supported by electrically driven wheeled assemblies for propelling the boom in a circular path about a central standpipe. The boom is in the form of a truss construction, the articulate connections between the sections of the pipe are disposed interiorly of the flow path and the sections of the boom are retained in alignment in either direction of movement. An end gun is provided and cam operated to irrigate the normally missed corners of a square area and the lugged wheels on the supporting assemblies are timed so that the lugs track thereby providing less disturbance of the ground surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
In an irrigation system having a boom movable over a relatively large land area and including an elongated pipe receiving water for discharge through a plurality of sprinkler heads, that improvement comprising a supporting truss structure for the pipe including a plurality of longitudinally spaced brace assemblies fixed to said pipe and depending therefrom, each brace assembly including a pair of opposed brace members of V-shaped configuration having the upper ends thereof attached to the pipe and depending in diverging relation, means retaining the lower apices of opposed pairs of brace members in spaced relation, and tension members connected to the apices of the brace members and extending and attached to the pipe at remote points for rigidifying the pipe and forming a truss support therefor, said pipe being sectional with the sections being joined by abutting end flanges, said tension members being attached to the pipe by extending through and being secured to a pair of abutting flanges.
Claim 2
Dependent Claim
159 words
In an irrigation system having a boom movable over a relatively large land area and including an elongated pipe receiving water for discharge through a plurality of sprinkler heads, that improvement comprising a supporting truss structure for the pipe including a plurality of longitudinally spaced brace assemblies fixed to said pipe and depending therefrom, each brace assembly including a pair of opposed brace members of V-shaped configuration having the upper ends thereof attached to the pipe and depending in diverging relation, means retaining the lower apices of opposed pairs of brace members in spaced relation, and tension members connected to the apices of the brace members and extending and attached to the pipe at remote points for rigidifying the pipe and forming a truss support therefor, said pipe being sectional with the sections being joined by abutting end flanges, said tension members being attached to the pipe by extending through and being secured to a pair of abutting flanges.
Claim 3
Dependent Claim
59 words
The structure as defined in claim 1 together with an end gun mounted at the end of the pipe for irrigating areas beyond the area irrigated by said pipe, and cam means controlling operation of the end gun in response to movement of the pipe to a position adjacent an area incapable of being irrigated by the sprinkler heads.
Claim 4
Dependent Claim
147 words
In an irrigation system having a boom movable over a relatively large land area and inCluding an elongated pipe receiving water for discharge through a plurality of sprinkler heads, that improvement comprising a supporting truss structure for the pipe including a plurality of longitudinally spaced brace assemblies fixed to said pipe and depending therefrom, each brace assembly including a pair of opposed brace members of V-shaped configuration having the upper ends thereof attached to the pipe and depending in diverging relation, means retaining the lower apices of opposed pairs of brace members in spaced relation, and tension members connected to the apices of the brace members and extending and attached to the pipe at remote points for rigidifying the pipe and forming a truss support therefor, the upper ends of the brace members being secured to angular clips rigidly affixed to the exterior surface of the pipe.
Claim 5
Dependent Claim
147 words
In an irrigation system having a boom movable over a relatively large land area and inCluding an elongated pipe receiving water for discharge through a plurality of sprinkler heads, that improvement comprising a supporting truss structure for the pipe including a plurality of longitudinally spaced brace assemblies fixed to said pipe and depending therefrom, each brace assembly including a pair of opposed brace members of V-shaped configuration having the upper ends thereof attached to the pipe and depending in diverging relation, means retaining the lower apices of opposed pairs of brace members in spaced relation, and tension members connected to the apices of the brace members and extending and attached to the pipe at remote points for rigidifying the pipe and forming a truss support therefor, the upper ends of the brace members being secured to angular clips rigidly affixed to the exterior surface of the pipe.
Claim 6
Dependent Claim
160 words
In an irrigation system having a boom movable over a relatively large land area and including an elongated pipe receiving water for discharge through a plurality of sprinkler heads, that improvement comprising a supporting truss structure for the pipe including a plurality of longitudinally spaced brace assemblies fixed to said pipe and depending therefrom, each brace assembly including a pair of opposed brace members having the upper ends thereof attached to the pipe and depending in diverging relation, means retaining the lower ends of opposed pairs of brace members in spaced relation, and tension members connected to the lower ends of the brace members and extending and attached to the pipe at remote points for rigidifying the pipe and forming a truss support therefor, the upper ends of the brace members being secured to clips rigidly affixed to the exterior surface of the pipe, said tension members being attached to the pipe by being secured to flanges on the pipe.
Claim 7
Dependent Claim
160 words
In an irrigation system having a boom movable over a relatively large land area and including an elongated pipe receiving water for discharge through a plurality of sprinkler heads, that improvement comprising a supporting truss structure for the pipe including a plurality of longitudinally spaced brace assemblies fixed to said pipe and depending therefrom, each brace assembly including a pair of opposed brace members having the upper ends thereof attached to the pipe and depending in diverging relation, means retaining the lower ends of opposed pairs of brace members in spaced relation, and tension members connected to the lower ends of the brace members and extending and attached to the pipe at remote points for rigidifying the pipe and forming a truss support therefor, the upper ends of the brace members being secured to clips rigidly affixed to the exterior surface of the pipe, said tension members being attached to the pipe by being secured to flanges on the pipe.
Claim 8
Dependent Claim
75 words
The structure as defined in claim 4 wherein said pipe is sectional with the sections being joined by abutting end flanges, said tension members extending through and being secured to a pair of abutting end flanges, each of said opposed brace members including two depending members defining a substantially V-shaped configuration having their lower end portions connected with each other and the tension members being connected with the lower end portions of the brace members.
Claim 9
Dependent Claim
59 words
The structure as defined in claim 5 together with an end gun mounted at the end of the pipe for irrigating areas beyond the area irrigated by said pipe, and cam means controlling operation of the end gun in response to movement of the pipe to a position adjacent an area incapable of being irrigated by the sprinkler head.
Claim 10
Dependent Claim
38 words
The structure as defined in claim 6 together with electrically driven mobile support means for said pipe, and timer means for controlling movement of the support means and the percentage of sprinkling time during each cycle of operation.
