Abstract
Self-ejecting chuck key for a gear chuck. A coil spring is arranged on the key of a gear chuck around the shank thereof and between means for holding same in position. Said spring includes a number of turns enlarged to clear the bevel gear of the key and preferably extends beyond said gear to a point between the small end of said gear and the end of the key. Said spring is made sufficiently soft that it can bear on both the body and the jaw nut of the chuck simultaneously without interfering with the effective and convenient operation of the key.
