ABSTRACT:
An improved spring hinge includes a capstan for securing one end of a torsion spring in a knuckle of the hinge. To prevent axial movement of the capstan out of the hinge knuckle and permit axial alignment of a radial cavity in the capstan with an aperture in the hinge knuckle, the capstan is provided with a shoulder which engages a projection extending into the hinge knuckle. Also disclosed is a frangible pin which removably extends through the aperture into the cavity to secure the capstan against rotation relative to the hinge knuckle.
