Abstract: A ratcheting system is used to wind a helical torsion spring around a torsion bar in a counterbalancing mechanism for an overhead door having multiple panel sections. The ratcheting system contains: (1) a cylindrical sleeve encompassing the torsion bar, the sleeve having longitudinal channels and being secured to the torsion bar at the winding end of the torsion spring; (2) a winding cone adapted to fit over the cylindrical sleeve and having a cone-shaped section connected to the winding end of the torsion spring, a plurality of radial openings for receiving winding bars, a first threaded radial opening containing a set screw, and a second threaded radial opening containing a pull pin, the pull pin having a spring-biased beveled projection that extends inwardly from the winding cone to contact the longitudinal channels of the cylindrical sleeve.
