Non circular gears (they don't have to be a geometrically constant shape

control elements where variable speeds are needed, e.g. quick return
mechanisms. For the life of me, however, I can't visualise a use for a
square cornered gear!
Two square gears, 90 degrees phased, should produce a cyclic speed variation. Drive a conveyor belt with that and it would work to shake the belt for smoothing out what it's transporting.
