Abstract
A spray boom assembly adapted for mounting on a vehicle, includes a pair of spray booms mounted for movement between a horizontally extended rigged-out position and an elevated rigged-in position. A single power cylinder moves the booms between the rigged-out and rigged-in positions and a lift link assembly is pivotally attached to the boom to effect elevation of the boom automatically upon rigging-in and depression of the boom automatically to its horizontally extended rigged-out position.

A flexible duct support arm of the type comprising an elongate structure for holding an elongate flexible duct (3) in a generally horizontal position and for sweeping and serpentine movement of said duct, said support arm having a proximate end (4) for mounting to a base (2) and a distal end (6), and attachment means (12) to attach said duct to said arm, characterized by:
- said support and comprising an elongate folding array of panels (10) in end-to-end relationship when in an extended position and a side-by-side relationship when in a folded position, said panels being joined together to permit pivotal movement of said panels relative to each other in a generally horizontal plane, said panels angling progressively upwardly from said proximate end to said distal end.
An apparatus comprising in combination an elongate flexible duct (3) supported by a duct support arm (1) for sweeping and serpentine movement of said duct of the type, comprising an elongate structure for holding said duct in a generally horizontal position and having a proximate end (4) for mounting to a base and a distal end (6), said support arm further comprising attachment means (12) to attach said duct to said support arm, characterized by;
- said support arm comprising an elongate folding array of panels (10) in end-to-end relationship when in an extended position and a side-by-side relationship when in a folded position, said panels being joined together to permit pivotal movement of said panels relative to each other in a generally horizontal plane, said panels angling progressively upwardly from said proximate end to said distal end.
