That sounds like a Shimano "Selecta" setup,

See: http://sheldonbrown.com/shimano1982/pages/35.html these were available in FF and rigid crank versions. They turned out to be rather unreliable, the spline circle was too small to withstand the torque.

To remove the cups, you use an old style Shimano "Boss" freewheel puller.
