Five cog wheels on one axis turned with different step widths every turn.

During one turn of the crank, the driving gears make 4/10, 8/10, 5/10, 2/10, 6/10 turn on the driven gears. The driving rod can be shifted to left or right, varying how many gears it turns. The closest relative in the museum could be so far the Columbus Egg.
