Shafts A and B are independently driven by gear trains of which the final links mesh with gears 1 and 6. Freely mounted on pin d of gear 1 is segment gear 2 which meshes with driven gear 5. Gear 5 rotates freely about shaft B. Round eccentric a is keyed to shaft B and is encircled by collar b of link 4. Link 4 is connected by turning pair C to pin 3 of segment gear 2. When gears 1 and 6 rotate continuously at uniform velocity, gear 5 rotates intermittently with nonuniform velocity.
