ABSTRACT:
A precision drive for a rotary potentiometer measuring the lineal displacements of a reciprocating machine unit, for the generation of switching signals, the drive including a control disc which is coaxially coupled with the potentiometer and driven by means of a timing belt which is attached to the moving unit. The drive belt may form a closed loop around a return roller which is carried by a guard case, it may have opposite angled-off runs of which one is preloaded for tension, or it may have one extremity attached to the control disc, under a torque bias.
