Abstract:
A rotatable plate for distribution of particulate material comprising,a circular horizontal plate having a center and an outer peripheral edge and being adapted to be rotated in a horizontal plane about its center, a plurality of spaced radial slots in the plate and extending from an inner end radially outward to an outer end which is located in spaced condition to the outer periphery of the plate, a vertical substantially rectangular fin having a lower edge slidably inserted into each of the slots and having a radial length less than the slots to permit sliding movement therebetween in a radial direction, interlocking surfaces on the plate and on the lower edge of the fin to permit the fin to be locked within the slot when the fin is moved to its maximum outer position within the slot whereby rotational motion of the plate will cause the fins to be retained in its locked position within the slot.
