The Geneva wheel, or Maltese cross, is a cam like mechanism that
provides intermittent rotary motion & is widely used in both low and
high-speed machinery. Although originally developed as a stop to
prevent over winding of watches, it is now extensively used in automatic
machinery, e.g. where a spindle, turret, or worktable must be indexed.
It is also used in motion picture projectors to provide the intermittent
advance of the film.
