Abstract
A carriage (30) for slidable movement along a track (100) having first and second parallel spaced apart guide surfaces (102, 104) is provided. The carriage (30) includes a base member (36). Structure (72, 78, 80) is mounted on the base member (36) for contacting the first and second parallel spaced apart guide surfaces (102, 104) on the track (100). The base member (36) includes a spring (50, 56, 58), such that as the base member (36) moves along the track (100), the base member (36) is resiliently compressed to thereby urge the structure (72, 78, 80) against the guide surfaces (102, 104) on the track (100).
