Abstract

An incremental speed reduction unit mounted between a fluid meter and a totalizer for reducing the speed at which the totalizer operates comprises a drive gear rotatably supported on a shaft and drivingly rotated by the fluid meter. A ring shaped gear integrally formed on an inside surface of the drive gear has a single set of gear teeth radially extending from the surface thereof. An idler gear rotatably supported on another shaft and drivingly rotated by the ring shaped gear has two sets of interspaced gear teeth of different lengths for incrementally causing the idler gear to rotate upon engagement of the teeth of the ring shaped gear. A driven gear connected to the first shaft is drivingly rotated by the idler gear and communicates such rotation to the totalizer.
