Not sure if it's the right term or not, but a change in spindle speed by changing the gearing between the motor and spindle, rather than changing the motor speed. A lot of older lathes do this by using the spindle pulley to turn a counter shaft which then turns the spindle. Lowers speed but increases torque.
What's the lowest spindle speed on your lathe?
