ABSTRACT:
In this arrangement the rolls of an odometer are serially built up on a support shaft and are sequentially interconnected by pinion gears which drivingly mesh with gear teeth internally of the rolls. These pinion gears are operatively mounted on partition plates which are interposed between each of the externally numbered rolls. The rolls are incrementally rotated by cooperating transfer and gear teeth on the rolls and the pinion gears so that distances traveled are accurately measured in predetermined increments. The rolls are initially stacked with number alignment and to maintain number alignment, the partition plates between each rolls are mechanically interlocked by pin and pocket construction that extend transversely from the extremity of a tangentially extending tang thereon. Adjacent pin and pocket of adjacent tangs are telescoped together to interlock all of the partition plates together so the odometer rolls are operatively interconnected and effectively unitized with numbers aligned for incremental drive from the input and are not subject to independent rotation from finger touch or higher loads when being installed or removed from the support therefor.
