Abstract
An apparatus for extending the wear life of flight bars used in chain-driven scraper conveyor systems by using a replaceable bar end. The bar end is securely attached to the flight bar body by a tongue protruding through an aperture in the bar end and interlocking with the clamp that secures the flight bar to the drive chain, without the use of additional fasteners. The replaceable bar end may be made from a different material than the body of the flight bar. Therefore, a wear resistant material could be used for the bar end, with the bar body and clamp made from conventional, typically more ductile materials. This invention therefore allows for the flight bar end to be replaced as required saving the cost of the main flight bar body and clamp.
