Continuous rotary converted into intermittent
rotary motion. The disk-wheel, B, carrying the stops, C, D, turns on a center eccentric to the cam, A. On continuous rotary motion being given to the cam. A, intermittent rotary motion is imparted
to the wheel, B. The stops free themselves
from the offset of the cam at every halfrevolution,
the wheel, B, remaining at rest
until the cam has completed its revolution,
when the same motion is repeated.
