block and tackle

(blŏk)
A device consisting of a fixed pulley and a movable one, in which the rope attached to the load is passed over the fixed pulley, around the movable pulley, then back around the fixed one. Each pulley can have multiple grooves or wheels for the rope to pass over additional times. The more times the rope is passed around the two pulleys, the less effort is needed to raise a load.
