Abstract: A conveyor platform is formed from a series of pivotally interconnected segments. Each segment has a stop block, and each stop block has two strike faces. Each strike face abuts against an opposing strike face on adjacent stop blocks when the platform is in a planar position. The stop blocks cannot be compressed, so, when the platform is carrying a load, the stop blocks prevent the platform from sagging. The platform turns as it travels around drive chain sprockets on the return portion of the cyclical drive chain pattern. When it turns, a gap is created between opposing strike faces on adjacent stop blocks. When adjacent segments of the platform emerge from the turn, the opposing strike faces come rapidly together. A bore extends inwardly from one of the strike faces on each stop block and a resilient urethane plug is mounted in the bore. The plug projects slightly beyond the strike face when the opposing strike face on the adjacent stop block is spaced from the plug-bearing strike face.

Abstract: The present invention relates to an interlocking flight for forming a flexible platform of a conveyor which may be of the continuous, vertical type. The flight is provided with oppositely-disposed first and engaging surfaces and an elongate portion having an upper surface generally normal to the engaging surfaces for forming a portion of the top surface of the platform. The flight is also provided with a pair of flanged portions which extend from opposite ends of the elongate portion. The flanged portions have opposing inner surfaces disposed generally normal to the elongate portion upper surface and a pair of opposing pivot pins, each of which extends from an inner surface. Also disposed at opposite ends of the elongate portion are a pair of land portions configured for rotatably receiving a corresponding flanged portion from another flight and having an opening for receiving a corresponding pivot pin therefrom to effect an interlocking engagement therebetween.
