Crank 1, rotating about axis y, is connected by a turning pair to slider 3. Axis z of the crankpin intersects axis y at point 0. Link 2 has a slotted member whose axis is curvilinear and coincides with an arc of a great circle of the sphere. Link 2 reciprocates in fixed guides whose axis coincides with an arc of the great circle of the sphere, perpendicular to axis x. Link 1 rotates and link 2 oscillates about mutually perpendicular axes y and x.
