Abstract
A low drift spray apparatus for controllably continuously pivoting the nozzle during discharge of spray composition whereby the emitting spray pattern describes the frustum of a cone as the nozzle pivots includes a flexible tubular segment of the liquid supply line adjacent to the nozzle; a pivotal support adjacent the nozzle for pivotally supporting an end of the flexible tubular segment about a fixed point; a fixed support at the other end of the segment, the segment being axially compressed to cause lateral displacement of a portion thereof; and a reciprocating subassembly adapted to continuously move the laterally displaced portion in a circular path substantially about an axis consisting of a line between the ends of the segment.
