Abstract: A calibration arrangement for an eddy cup-type speedometer is disclosed in which a magnetic shunt is carried on a bearing sleeve located on a magnet shaft, with the shunt located intermediate the frame backwall and the shaft magnet. A spring biases the shunt against rotation relative to the magnet. Aligned apertures in the frame and housing backwalls located radially outwardly of the magnet shaft and radially inwardly of the shunt periphery enable receipt of a tool for engaging a rearwardly extending tang on the shunt to hold the shunt against rotation while the magnet is rotated to thereby adjust the angular relationship between the magnet and shunt for calibrating the speedometer.

Abstract: The following specification describes an arrangement for locking a counter or odometer on subtractive operation together with a clutch automatically operated on locking to disengage the gear train and avoid damage to the train and effective on normal or additive operation to engage the gear train. A simple spring biased ratchet arrangement between one of the drive wheels and an adjacent higher digit order wheel is also used to permit additive operation and prevent subtractive counter or odometer operation. An additional feature provides a signal in the event of tampering with the odometer by moving one of the higher digit order dials.
