ABSTRACT:
A powder dispensing assembly including an elongated chute having opposite ends pivotally supported for rotation about a pivot axis within an elongated housing and having a funnel-shaped cross section with a wide upper portion and a narrow lower portion. A dispensing platform is integral with the rear wall of the chute and extends forwardly beneath the front wall and slopes upwardly to a lip over which particles of powder move to define a falling curtain of powder particles. A supply platform is supported just above the pivot axis and receives powder from an elongated slot and supplies powder to the dispensing platform as the powder falls downwardly through the chute. The supply platform is wider than the angle of repose of the powder supplied thereto so that when the supply platform is not moving powder is not being supplied to the lower dispensing platform. An electromagnet cooperates with a spring plate which is, in turn, connected by a rod through the housing to the rear wall of the chute. The electromagnet operates on 60 cycle AC and, when energized, sets up a magnetic field to bend the spring plate to rotate the chute in a counterclockwise direction about its pivot axis and between cycles the spring plate springs back and returns the chute by rotating it in the clockwise direction. The upper supply platform, therefore, rocks about the pivot axis to supply powder to the lower dispensing platform.
