ABSTRACT:
A pair of conveyor pan immobilizing subassemblies are disclosed for engaging the opposite sides of a conveyor pan to stabilize the pan in a first direction transverse to the conveyed direction of the pan. In one embodiment, each subassembly is comprised of a plurality of pan engagement assemblies, each pivotally mounted for depression in a vertical axis by an off-centered pan, and each spaced further from the conveyor pan in the first direction, such that the pan is serially engaged by the assemblies as a result of pan movement resulting from, for example, loading or unloading of the pan. In another embodiment, the subassembly comprises a roller rotatably mounted for rotation by a pan being moved in the conveyed direction and resiliently mounted for depression by an off-centered pan. The roller is further mounted such that the surface thereof, when in engagement with the conveyor pan, forms an acute angle with a vertical axis, thereby resulting in a wedging engagement of the conveyor pan by both of the subassemblies' rollers.
