Abstract
Abstract An orbital irrigation system employing a rotatable pivot head, as a supply take-off, comprises a sprinkler conduit issuing horizontally from the pivot head; the sprinkler conduit including a multiplicity of distally disposed sprinkler heads, the sprinkler conduit being carried by wheel sets disposed at intervals along the length of the sprinkler conduit, one or more of the wheel sets being provided with a gear box driven by combination means for providing mechanical rotation to the gear box and for dispensing a spray of water supplied from the sprinkler conduit, horizontal and lateral stressing including a multiplicity of masts issuing transversely at intervals from the sprinkler conduit, and a cable fastened to the conduit at a point distally from the pivot over terminal ends of the masts and to alternate bases of the masts at the conduit, and a drive carriage assembly mounted distally from the terminal end of the sprinkler conduit opposite the pivot.

Claim 1
Independent Claim
208 words
An orbital irrigation system employing a rotatable pivot head as a supply take-off, comprising: a sprinkler conduit issuing horizontally from said pivot head, said sprinkler conduit including a multiplicity of distally disposed sprinkler heads, said sprinkler conduit being carried by wheel sets disposed at intervals along the length of said sprinkler conduit, each wheel set comprising an A-frame mounted at its apex transversely to said conduit and wheels journally mounted at the lowermost terminal ends of said A-frame, horizontal and lateral stressing including a multiplicity of masts issuing transversely at intervals from said sprinkler conduit, and cable fastened to said conduit at a point distally from said pivot over terminal ends of said masts to alternate bases of said masts at said conduit; and a drive carriage assembly including a frame mounted distally from the terminal end of said sprinkler conduit opposite said pivot, wheels disposed transversely to said supply conduit mounted to said frame, and a motor and transmission mounted on said frame and mechanically connected to said wheels, at least one of said wheels being provided with a gear box driven by combination means and means for providing mechanical rotation to said gear box and for dispensing a spray of water supplied from said sprinkler conduit.
Claim 2
Dependent Claim
208 words
An orbital irrigation system employing a rotatable pivot head as a supply take-off, comprising: a sprinkler conduit issuing horizontally from said pivot head, said sprinkler conduit including a multiplicity of distally disposed sprinkler heads, said sprinkler conduit being carried by wheel sets disposed at intervals along the length of said sprinkler conduit, each wheel set comprising an A-frame mounted at its apex transversely to said conduit and wheels journally mounted at the lowermost terminal ends of said A-frame, horizontal and lateral stressing including a multiplicity of masts issuing transversely at intervals from said sprinkler conduit, and cable fastened to said conduit at a point distally from said pivot over terminal ends of said masts to alternate bases of said masts at said conduit; and a drive carriage assembly including a frame mounted distally from the terminal end of said sprinkler conduit opposite said pivot, wheels disposed transversely to said supply conduit mounted to said frame, and a motor and transmission mounted on said frame and mechanically connected to said wheels, at least one of said wheels being provided with a gear box driven by combination means and means for providing mechanical rotation to said gear box and for dispensing a spray of water supplied from said sprinkler conduit.
Claim 3
Dependent Claim
66 words
The apparatus of claim 1 wherein said combination means for dispensing and means providing mechanical rotation and for dispensing a spray of water comprises a jet supplied with water from said sprinkler conduit mounted on a post and a bladed wheel whose shaft is mechanically connected to said gear box driving said wheel set with said blades intercepting said jet of water at a predetermined point.
Claim 4
Dependent Claim
22 words
The apparatus of claim 1 wherein said masts are mounted at the same points on said sprinkler conduit as said wheel sets.
Claim 5
Dependent Claim
26 words
The apparatus of claim 3 wherein said wheel sets and said drive carriage are disposed at substantially equal intervals over the length of said sprinkler conduit.
Claim 6
Dependent Claim
61 words
The apparatus of claim 1 wherein a portion of said sprinkler conduit is cantilevered from said drive carriage, and said drive carriage is provided with a rearwardly, horizontally and transversely disposed mast provided with a cable fastened to said cantilevered terminal end over the terminal end of said mast and connected at the base of the next adjacent forewardly disposed mast.
Claim 7
Dependent Claim
28 words
The apparatus of claim 1 including under bracing comprising triangular frame members fastened at the apexes at intervals along said supply conduit, being connected by cables under tension.
