Patent ID: 7243779

Claim:
A reciprocating slat conveyor, comprising: framework providing a support for fixed and movable conveyor slats, said framework defining a window sized to receive three transverse drive members and allow said drive members to reciprocate in the window longitudinally of the conveyor; three transverse drive members in said window; laterally spaced apart fixed slats, extending longitudinally of the conveyor and supported on the framework both forwardly and rearwardly of the window; said fixed slats extending longitudinally over the window; said fixed slats supporting elongated bearings that extend length wise of the slats substantially throughout the full length of the slats; laterally spaced apart movable conveyor slats extending longitudinally of the conveyor between the fixed slats, said movable conveyor slats being divided into sets, one set for each transverse drive member, wherein each set of movable conveyor slats is connected to a related one of the transverse drive members, so that each set of slats will move with its transverse drive member; said movable slats having portions that rest on the bearings so that during longitudinal movement of the movable slats said slats will move on the bearings; wherein the fixed conveyor slats are box beams having spaced apart side walls, a top and a bottom spaced below the top and extending between the side walls; and wherein the movable conveyor slats comprise longitudinal box beams that are disposed between the fixed conveyor slats, said box beams having spaced apart sidewalls, a top and a bottom spaced below the top and extending between the sidewalls.
