44.272 MOTOR DRIVEN RESET MECHANISM FOR CUMULATIVE DEMAND REGISTER Abstract of the Disclosure A meter includes a single sweep hand dial for indicating maximum demand in a predetermined time period as well as a multi- dial decade register for recording cumulative demand. The sweep hand dial is driven by a pusher gear. A pusher arm urges the pusher gear in a first rotational direction to record maximum demand during the period. To reset the mechanism, a button is pushed manually to axially displace a reset gear into meshing engagement with a relatively high speed gear train driven by the timer motor. As the reset gear is thus moved, pins on the reset gear are displaced from stowage slots in a plate, and as the reset gear rotates, the pins ride on the plate until the reset gear completes a full cycle of operation during which time another pin on the reset gear engages a second tab on the pusher gear to reset the pusher gear in a rotational direction counter to that in which the pusher arm had rotated the pusher gear. During reset, the pusher gear drives a memory gear train provided with a unidirectional drive to transfer the maximum period demand to the cumulative demand register. When the reset gear completes its cycle, the pins are forced back into their stowage slots to disengage the reset gear from its drive. A reset spring urges one of the pins on the reset gear against an edge of its stowage slot to insure accurate zero reset of the reset gear. One tab on the pusher gear is adjustable to facilitate synchronization between the pusher arm and the reset gear.
