This article gives, for the first time, a complete description of the machine developed around 1850 by Jean-Baptiste Schwilgué (1776-1856) for the mechanical computation of arithmetic sequences, of particular use in setting gear-cutting machines. The second part in a two-part series, this article presents the details behind the machine's basic operations.
