DEFINITION

Classification: 242/371

With spring motor:

(under subclass 370) Subject matter wherein the drive mechanism includes a resilient member (spring) adapted to store energy that is selectively released to cause winding or unwinding of the elongated material to or from a coil.

(1) Note. This and the indented subclasses provide for a reeling device having a spring motor (e.g., a coiled spring or twisted rubber band) serving as the source of power, but not a spring device exclusively used to absorb movement or couple elements.
