Abstract
An article removal platform assembly with laterally movable finger plate is provided particularly suitable for abutting a conveyor belt as it passes over a sprocket wheel to remove glass articles and broken glass fragments from the belt. The generally rectangular finger plates are mounted in a lateral sliding configuration to a planar platform by at least three fasteners extending through mounting apertures through the finger plates 50, spaced to prevent lateral or longitudinal tilt. The mount has elongated fastening members adjustably aligned to let fingers mate in a conveyor belt and freely slide laterally a limited amount in either direction. Thus, the finger plates can slide side-to-side to follow belt wander when the fasteners engage ridges of the apertures through the finger plates. Also provided are snap-in caps for the apertures for maintaining a planar discharge surface having a constant coefficient of sliding friction that does not accumulate residue. The conveyor belt outer surface is formed by ribs defining channels for receiving the finger plate fingers disposed adjacent to the sprocket wheel to form therewith a co-planar discharge route. The fingers are stubby plates …
