Abstract
A three-armed spider frame is provided including depending supports at the free ends of its arms and a center mount outwardly from which the three arms radiate. An upwardly opening hopper is journaled from the frame for rotation about a central upstanding axis and includes a plurality of lower outlets spaced outwardly from and about the hopper rotation axis. Each of the outlets includes dispensing structure for dispensing fluent material discharged from the outlets in sector-shaped horizontal patterns and structure is provided whereby the horizontal patterns may be selectively angularly displaced about the corresponding outlets. Further, variable speed motor structure is drivingly coupled to the hopper for rotating the latter relative to the frame and the interior of the hopper is divided into a plurality of upwardly opening compartments each serving a corresponding lower outlet.
