Abstract: A device for use with a toy track layout to count the number of laps traversed by a toy vehicle, comprising a track section with a slot and a pivotally mounted lever which extends through the slot so it can be pivoted down by a vehicle moving along the track. The lever operates an escapement that allows a number wheel to advance to display a new lap count. A single-coil spring is used to move the number wheel and to urge the lever to a position where it projects from the track.
