Patent ID: 7934715

Claim:
A mounting arrangement for mounting an ingestion assembly within a singulating apparatus, the singulating apparatus operative to singulate sheet material which is fed along a feed path, the mounting arrangement comprising: a radial bearing mount connecting the ingestion assembly to a support structure of the singulating apparatus, the radial bearing mount pivotally mounting about a pivot axis substantially orthogonal to the sheet material feed path and operative to pivot the ingestion assembly from an operating position to an idle position; and an over-center mechanism coupled to the radial bearing mount for biasing the ingestion assembly about the pivot axis such that the ingestion assembly is forcibly held in each of the operating and idle positions, the over-center mechanism including at least one telescoping strut pivotally mounting about a pivot axis to a support structure of the singulating apparatus and defining a line of action passing through the pivot axes of the radial bearing mount and the at least one telescoping strut, the line of action projecting radially from the pivot axis of the radial bearing mount, the telescoping strut operative to extend when disposed to either side of the line of action and apply a biasing moment about the pivot axis of the radial bearing mount when the strut is disposed to either side of the line of action.
