A transfer mechanism has a tool mounting surface movable in a inverted U-shaped path back and forth between spaced stations thereby making the mechanism useful, for example, as part of a pick and place device for picking up articles one at a time, or in groups at a time, from one first station and placing them at the other station. The U-shaped motion is achieved by a first body for movement relative thereto a second axis perpendicular to the first axis. The movement of the two bodies along their respective axes is achieved by a single oscillating crank arm engage-able with both bodies in such a manner as to obtain smooth gentle acceleration and deceleration of the two bodies with a minimum amount of driving force and capable of providing a short cycle time if desired.
