ABSTRACT:
A mail transporting mechanism for transporting pieces of mail through a mail handling system. The mechanism comprises a frame supporting a number of rotative rollers. A friction belt is stretched over the rollers, and conveys a letter through the mechanism as the rollers turn. The rollers are mounted on a movable yoke assembly, which is spring biased to provide positive contact between the belt and the mail. The roller assemblies are pivotable from an engaging position to a non-engaging position, by means of a slidable bar carried on the frame. When the bar is made to slide, a bracket fixed to each of the roller assemblies is made to pivotably cam causing the roller assembly to disengage. The bracket has means for easily setting the engaged position of the assembly to a given level of contact with the mail.
