Abstract
An improved 'reset' type odometer assembly having counting wheels rotatably supported on a shaft and interconnected by pinion gears therebetween for sequential counting as mileage progresses. A gear wheel between each of the counting wheels is engaged on its right side by a pinion gear which moves with each revolution of the counting wheel located to its right. In turn the gear wheel engages an outer pawl on a molded ratchet spring to cause corresponding rotation of the leftwardly positioned counting wheel. The ratchet spring also has an inner pawl which is engaged by a groove in the shaft when rotated to cause the ratchet spring and counting wheel to rotate during a reset mode of operation. During resetting, the gear wheel and pinion gears are stationary and the outer pawl moves between circumferentially spaced detents in the gear wheel. The ratchet spring itself is formed with inner and outer hoop portions and is of a relatively flexible plastic material to permit movement between the hoop portions and the two pawls.
