IMPRQVEMENT IN EYEGLASSES.

Specification forming part of Letters Patent No. 165,199, dated July 6, 1875; application filed May a, 11-375.

To all whom it may concern: 7

Be it known that I, JOHN J. BAUSOH, of

Rochester, in the county of Monroe and State of New York, have invented a new and use ul Improvement in Eyeglasses, of which the following is a specification A Figure 1 represents one of my improved eyeglasses. Fig. 2 is a detail view of a portion of the same. Fig. 3 is a detail section taken through the line .1; .r, Fig. 1. Fig. 4 is a detail section taken through the line 3 3 Fig. 3. Fig. 5 represents a modification of the same. Fig. 6 is a detail section ofthe same take through the line 2 z, Flg. 5.

Similar letters of'ret'erence indicate corresponding parts. i

The invention will first be described in connection with drawing, and then pointed out in the claim.

A represents the frames or glass parts, which are connected by the connecting or how spring B, secured to projections formed upon the upper parts of said frames A. U are the nosepieces, the upper parts or halves of which are secured to light springs D. The springs D extend along the sides of the nose-pieces 0, next the glass frames A, and their lower ends project a little below the lower ends of the said nose-pieces G, and are secured to projections formed upon the lower parts of the said frames A. The upper ends of the springs D project above the upper ends of the nose pieces 0, are bent over, and have heads formed. upon them which pass through slots in the guards E. The guards E may be inward extensions of the ends of the connecting or how spring B, as shown in Fig. 5, or they may be separate pieces, as shown in Fig. 1.

If desired, the slot may be formed in the bent-over upper ends of the springs D, and the heads may be formed upon the ends of the guards E, as shown in Fig. 5.

By this construction, when the eyeglasses are in use, the nose-pieces O and springs D take about the position shown in Fig. 2,

biingiug mm) play the elasticity of the lower part of the said springs I), and the elasticity of the lower part of the nosepieces U, which enables the nose-pieces to adjust themselves to the nose of the wearer moreaccurately, and with a more delicate pressure, than when they are constructed in the ordinary way. By this construction, also,'the upper ends of the nose-pleces are kept in place, and the lower parts, when the eyeglass is not in use, are held firmly down on the nose-piece. springs by the elasticity of the latter, thus preventing the nose-pieces from being caught and breaking, to which they are liable when either end of the nose pieces is open. One of the frames A is provided with a handle, F, and catch-pin G, and the other frame is provided with a catch, H, to con tine the frames when folded together.

Having thus described my invention, Ielaim as new and desire to secure by Letters PM? ent- An eyeglass provided with self= adjusting nose-pieces closed at both ends, as and for the purpose described.
