    Abstract: A system for safely and effectively winding a garage door spring features a hub assembly having a cylindrical hub with a cylindrical channel located there through. The hub assembly features a wheel gear located around the hub and a plurality of engagement prongs designed to snuggly engage a torsion spring winding cone. The hub assembly is divided into a first hub component and a second hub component. The system features a base with a semi-cylindrical notch and an arcuate lid pivotally located thereon. A plurality of support rollers are adjustably located around an inside of the notch and the lid. The hub assembly is positioned on the support rollers.

  • Patent number: 8567567
    Abstract: A winding tool for tightening a torsion spring for a sectional overhead door. The winding tool features two half hub assembles that wrap around an overhead door shaft, wherein a translational sprocket is disposed on the hub assemblies. The hub assemblies connect to the winding cone of a torsion spring via fingers that engage the hub assemblies. A winding box is removably attached to the hub assemblies. The winding box features a worm gear that engages the translational sprocket. A handle bar can be rotated with a drill to cause rotation of the worm gear. Rotation of the worm gear causes rotation of the translational sprocket and ultimate winding of the torsion spring.
