Abstract: A mounting and biasing mechanism for maintaining an essentially constant tracking force between a frictionally driven distance measuring metering wheel and a measurement surface, along which the wheel rolls in use, is described. An end-loaded leaf spring of desired stiffness provides the desired tracking force, and is preloaded and predeflected as a slender column so that the wheel follows undulations of the measurement surface with essentially no change in the force applied by the spring to the wheel.

Abstract: There is described a mounting for a frictionally driven distance measuring metering wheel which provides adjustment for the tracking engagement as well as the angle of contact between the metering wheel and the measurement surface along which the wheel rolls in use. A frame plate is part of the housing structure for the metering wheel and a mounting plate is movable along the measurement surface. The frame plate has a planar surface which contacts a pair of curved support surfaces projecting above the mounting plate. The curved support surfaces contact the frame plate along a line perpendicular to the axis of rotation of the metering wheel and closely adjacent the plane of the metering wheel. The frame plate is tiltable about these support surfaces and also slidable transversely on the surfaces to provide positioning adjustment for the metering wheel.

Abstract: A distance measuring device having a variable radius frictionally driven measuring wheel is described. The repeatability of measurements made by the measuring device is improved by providing a plurality of randomly spaced apart ridges on the periphery of the measuring wheel with the long axis of the ridges extending transverse to the circumference of the wheel. Accuracy of measurement is assured by an adjusting method wherein the wheel is disengaged from the measurement surface during adjustment and the wheel moved to prevent it from following in a track previously made in the measurement surface.

Abstract: A mounting and biasing mechanism for maintaining an essentially constant tracking force between a frictionally driven wheel and a measurement surface, along which the wheel rolls, is described. The mechanism includes a base member and a carrier member having resilient means operatively coupled between them for biasing the carrier member relative to the base member along a predetermined path of movement defined for the carrier member. The predetermined path of movement of the carrier member is defined by flexure means connected between the base and carrier members. The flexure means is arranged to define three spaced laterally deflectable columns, aligned normal to the path of movement between the base and carrier members, to provide three essentially frictionless, highly compliant points of connection between the base and carrier members.
