Abstract
A line dispensing and retracting device comprising PA1 (a) a reel having a hub about which the line is wound as the reel rotates, PA1 (b) structure mounting the reel for rotation relative thereto, and about an axis, PA1 (c) a generally radially movable element carried by the reel to move between an inwardly retracted position in which the reel is free to rotate, and an outwardly extended position in which the movable element prevents further dispensing of the line, PA1 (d) and the line wound on the reel in operative relation with the movable element to control said element's movement in response to reel rotation, PA1 (e) the line including an inner winding located to urge said element outwardly relative to the reel in response to reel rotation in a line dispensing direction, and also to prevent outward movement of said element until a portion of said inner winding proximate said element moves relatively away from the reel.
