Abstract
The invention provides a mount for attachment to a link chain conveyor, especially--but not exclusively--for use in an automatic packaging machine. The mount has two pivot points of attachment to prevent unwanted motion caused by centrifugal forces as the mount circles a sprocket wheel. One of the two pivot points is a pair of tracks having wear resistant nylon blocks mounted on them to provide lost motion. Responsive to each lost motion extension, the block rubs the tracks to clean them of debris.
