A reciprocating action drive having a magnetically sprung overrunning clutch with sprags that contain permanent magnets, is disclosed. The overrunning clutch has inner and outer shafts disposed to rotate about a common axis, and pivoting sprags that incorporate a permanent magnet, located between them. The sprags are shaped and sized, and located and sprung by magnetic attraction, such that the shafts rotate freely past each other in one direction, but lock together when attempted to be rotated in an opposite, lockup direction. A drive shaft is connected to either the inner or outer shaft of the overrunning clutch, and a lever arm is connected to the other shaft. When the lever arm is moved in a first rotational direction, the drive shaft is driven in that same direction. However, when the lever arm is moved in the opposite direction, the drive shaft is not driven as the overrunning clutch freewheels.
