TOLERANCE ADJUSTER AND WEAR DEVICE FOR SORTATION SYSTEM

A tolerance adjuster and wear device, e.g. spring clip, is provided for automatically adjusting the tolerance or clearance between a pusher shoe surface and an adjacent surface of a linear slat of a positive displacement sorter. The spring clip includes an engagement portion to couple the clip to a pusher shoe and a wear portion to automatically bias or adjust a tolerance between the pusher shoe and a corresponding slat. The engagement portion includes a retainer, in the form of a pair of opposing elastic grips or teach that are insertable through a receiver in a surface of the shoe. The wear portion includes a wear surface and spring element, such as a spring arm or convex dome. The spring element is elastic to provide a consistent and automatic bias against the slat surface. Preferably, the spring clip is extruded from a resilient, wear-resistant self-lubricating polymer.
