Conveyor frame with removable tracks

A conveyor frame for a chain-driven conveyor, comprising:

• an elongated frame member having an exterior side and an interior side and defining elongated upper and lower chambers, said upper chamber defining a top opening and defining a pair of parallel, upwardly-opening, rail-receiving slots lying in said upper chamber below said top opening;
• a pair of elongated support rails having a substantially rectangular cross-section, said support rails being received in said respective rail-receiving slots and projecting upwardly out of said slots, said rails being adapted to serve as a support surface for the rollers of a roller chain;
• wherein said rails can be installed on said elongated frame member and removed from said elongated frame member by lifting them up out of said rail-receiving slots and passing them through said top opening;
• a pair of inclined, elongated pockets extending adjacent to said pair of rail-receiving slots, said inclined, elongated pockets being adapted to serve as pilots for directing retaining screws, such that retaining screws extending through said inclined, elongated pockets would contact their respective rail members and push downwardly and inwardly on their respective rail members;
• said top surface defining a vertical guide slot adjacent to the exterior side of said frame adapted to receive a rectangular cross-section piece of bar stock to serve as a guide;
• and
• said interior side defining a horizontal guide slot adjacent to the top surface adapted to receive a rectangular cross-section piece of bar stock to serve as a guide.
