Two trammels of Archimedes
youtu.be/-GzBOU3v4_g
are placed with a defined offset.
Their input blue gear shafts rotate in the same direction and at the same speed thanks to belt drives. The brown pulley is used to receive rotation from an external motor (not shown).
The output orange sliders of the two ellipse mechanisms are connected together by yellow and pink plates. These plates have reciprocating linear motions in the directions that are perpendicular to each other. Furthermore, the plates are always kept horizontal.
Perhaps this design belongs to machines that do nothing but it does bring about fun movements.
