This mechanism is one of the very few that are still taught in engineering schools. It is the quintesential example of what Reuleaux called a kinematic chain. In this model the linkage is demountable from the pedestal so that the instructor can fix different links thereby obtaining four inversions as Reuleaux would say of the same fundamental linkage. These inversions can be realized with the help of the model pedestal H1. (See Fig. 21, Reuleaux's Kinematics of Machinery.) For example in one inversion a rotary motion of the crank link produces an oscillatory motion in the driven link (Fig. 11), while in another inversion a rotary motion of the crank produces a rotary motion of the opposite link (Fig. 24).
