Click to enlargeClick to enlarge Description

Link 1 rotates about fixed axis A and carries two pawls 3 which turn about axes B and C. Link 2 rotates freely about axis A and has recesses b. When driving link 1 rotates counterclockwise, pawls 3 engage recesses b and link 2 is rotated in the same direction. When link 1 stops, link 2 can continue to rotate by inertia. If link 1 is rotated clockwise, pawls 3 turn out of engagement and wheel 2 remains stationary.
