A governor assembly (16) is provided including a sheave (18) rotatably mounted on a shaft and a ratchet disc (30) mounted on the shaft. Rotation of the ratchet disc (30) is restricted. An overspeed assembly (40) includes a swing jaw (42) mounted to the sheave (18). The swing jaw (42) is movable between a normal position and a tripped position. The swing jaw (42) is biased into the tripped position. When the swing jaw (42) is in the tripped position, rotation of the sheave (18) in a first direction is restricted. A tripping lever (44) is pivotally mounted to the sheave (18) and is configured to cooperate with the swing jaw (42). Rotation of the sheave (18) in a second, opposite direction is configured to automatically move the swing jaw (42) against its bias to the normal position.
