ABSTRACT:
A flip-over mechanism for a cyclometer register includes an eccentrically balanced fly-wheel freely rotatable on a drum shaft between a driver drum and a first driven drum, each drum being marked with decimal digits 0-9. The driver drum is driven in smooth rotation by a measuring device whose measurements are to be accumulated. At a certain point in its rotation, the driver drum engages and begins rotating the fly-wheel. As the driver drum is rotated into a position at which it performs a 9-to-0 transition, the fly-wheel becomes overbalanced and rotates forward on its stored potential energy until a striker thereon engages a tooth of a first carry pinion located between the fly-wheel and the first driven drum. This applies a momentary forward tap to the first carry pinion. The tap on the carry pinion provides a substantially instantaneous carry operation to be performed in all of the driven drums which are in position to require a carry. The mass of a replaceable weight on the fly-wheel is selected to apply the correct imbalance for producing a smooth operation.
