Driver 1 rotates about fixed axis A and carries pin a which consecutively engages slots d of Geneva wheel 2. Geneva wheel 2 rotates about fixed axis B and its slots d are helical and located symmetrically at angles of 36° between the axes of adjacent slots. Driver 1 carries concentric locking member b which engages the spaces between fingers e on Geneva wheel 2 to prevent its unintentional rotation during its idle periods. Axes A and B do not intersect and are perpendicular to each other. When driver 1 rotates continuously at uniform velocity, Geneva wheel 2 rotates intermittently at nonuniform velocity with ten rotation periods tᵣ and ten idle periods tᵢ. The time of one revolution of driver 1 is T=tᵣ+tᵢ. The angle of rotation of Geneva wheel 2 to each revolution of driver 1 is ϕ_G=36°.
