Abstract: This invention discloses a bow and hinge mounting assembly for pivotally securing a bow to an eyeglasses frame having a upper frame portion and a lower frame portion. In one embodiment of this invention, a single mounting screw is used to secure the upper portion of the eyeglasses frame to the lower portion of the frame and to pivotally mount the bow to the eyeglasses frame. The lower portion of the eyeglasses frame has a lower mounting plate that protrudes outward therefrom. A mounting pin rigidly secured to the lower mounting plate is arranged to pivotally engage a hole in the mounting portion of the bow. The bow is kept in place on the mounting pin by means of a upper retaining plate. This plate protrudes outward from the upper portion of the eyeglasses frame and is arranged to contact the top of the mounting pin to thereby retain the bow in place upon the mounting pin.

Abstract: This invention discloses a nose piece assembly for adjustably mounting a nose piece to an eyeglasses frame having a pair of correction lenses connected to each other by a rigid cross piece. In the preferred embodiment, the nose piece assembly comprises a nose piece for engaging the nose of the wearer, a mounting member for adjustably connecting the nose piece to the cross piece of the eyeglasses, and a guide way for maintaining the alignment between the nose piece and the eyeglasses. The outer dimensions of the nose piece are standardized while the inner size and shape are selected in accordance with the facial features of the wearer to ensure maximum visual acuity and comfort. The mounting member consists of a long slender mounting pin having a threaded end portion arranged to engage an internally threaded hole in the nose piece. The mounting member is rotatably mounted on the eyeglasses frame and raises or lowers the nose piece in response to rotational motion imparted to the mounting member.
