Adjustable and Detachable Bow for Spectacles.

Patent for a temple bow for spectacles which is secured to a lens frame and is adjustable to “accommodate the angle of vision of the wearer” (lines 89-90). The connection joints between the bow and lens frame allows adjustment without bending or twisting the bow, providing a more durable bow and frame.
