The sprocket has a first pair of teeth spaced a predetermined circumferential distance from each other on a pitch circle about the sprocket and a third tooth being spaced a distance less than the above mentioned predetermined distance from the trailing tooth of the first pair of teeth. The leading drive surface of each tooth engages and drives the chain around the sprocket.
