Abstract: The torsion spring winding device of the present invention comprises a gear having annular teeth thereon and additionally having means for detachably securing the gear to the free end of a torsion spring. A worm gear support is rotatably mounted to the gear so as to permit the gear to rotate independently of the worm gear support. The worm gear support carries an elongated worm gear in driving engagement with the annular teeth of the gear, and additionally includes a stop means for engaging the wall upon which the torsion spring is mounted. The method of the present invention comprises attaching a rotatable gear member having a plurality of peripheral teeth thereon to the free end of a torsion spring, engaging the peripheral teeth of the gear member with a worm gear, holding the worm gear mechanism against swinging movement with respect to the spring whereby the worm gear prevents rotation of the gear member and the free end of the spring with respect to the fixed end of the spring, rotating the worm gear to drive the gear member in a rotational direction whereby the free end of the torsion spring is rotated with respect to the fixed end thereof, and detaching and removing the gear member from the spring.
