<p>Geared drive for reset trip odometer in which a transfer tooth (90) on each of the rotatable odometer wheels (12,14) is immediately ahead of a tooth space (84) in a circular track (86) on the odometer wheels for tracking wide pinion teeth (80) of the associated transfer pinion gear (38-42) and laterally clear of narrow pinion teeth (82). With the wide pinion teeth normally riding on the track of the odometer wheel, there is a gear locking action if a reverse drive occurs to limit wheel droop from a reference line and anti-locking action when reset is attempted so that the odometer wheels can be forwardly driven to record trip distances.</p> |
