Title: Drive system for mensuration stages or the like

Abstract: The improved drive system for linearly translating the sample platform of a mensuration stage along two axes comprises two drive bars, each bar having one tapered lontitudinal edge. The X-Y position adjustment of the sample platform is controlled by two manually operable, coaxial controls which are coupled to V-grooved drive wheels. Leaf springs formed in the ends of each drive bar urge the tapered edge of each drive bar into enhanced, frictional engagement with a drive wheel. Each end of the drive bars are also formed to cause the drive bar to frictionally disengage from the drive wheel as the sample platform is driven to its limit in either direction along either axis.
