An odometer automatically records the exact mileage,registering every 35 ft. and can be set back to zero at theend of every day, week or month as desired. To conformto the service required of it, the recorder operates on a time Internal Mechanism of the Loco-Recorder idle time is thus easily calculated. .\ii actual reproduc-tion of the record of a switch engine for four hours, isshown in the illustration.
