Model: S10 Inversion of an Ellipse Linkage of the Second Kind by Nehrlich
When the crank is included in the mechanism, this is a six-bar linkage with a higher pair sliding joint (i.e., the sliding block link is missing in the slot) (See also Model S-11,12) Many compound linkages can generate mathematical curves such as ellipses and by Reuleaux’s title, an inversion of this kinematic linkage will draw an ellipse. In this inversion however, the linkage is used to move in a vertical straight line from the sliding pin in the slot.

The famous Russian Kinematician I.I. Artobolevskii ( 1964) wrote a book on the use of linkages to draw mathematical curve. (See also reference below)
