SELF-ALIGNING, NON-TIPPING BAILPLATE

The design concept presented here is for a bailbar or bailplate that will insure a constant contact zone between the bailbar and a stack of documents positioned on the feed belt of either a retard feeder or bottom-type paper feeder.

To provide the constant contact zone, the bailplate must be free to orient itself so as to seat flat on a stack of documents regardless of the stack height.

The intent here is to have the bailplate free to pivot on trunnions with sufficient force (i.e., load) on the bailplate to cause the bailplate to seat on the top of the stack surface. To insure that the bailplate will not deviate from a flat position after the last sheet has fed through, due to the higher friction forces developed between the bailplate and the moving feed belt, the bailplate is extended upstream well past the point where the feed belt and bailplate are initially in contact.

SELF-ALIGNING, NON-TIPPING BAILPLATE (Cont'd)

Referring to the figure, the bailplate 4 is pivotally supported by trunnions 5 on two arms 6, 7. Arms 6, 7 are, in turn, supported by a cross shaft 8 mounted on the document handler frame. Torsion springs 10, 11 coupled between arms 6, 7 and shaft 8 provide about 0.4 pound downward force on the bailplate 4 and...
