    N° 17,785 A.D. 1800 Date of Application, ifth Aug., 1896 Complete Specification Left, 10th May, 1897—Acceptei, 12th June, 1897 PROVISIONAL SPEOIFICATION. [L!ommunicate(J from abroad bv Jacob W. Riglander, of New York, United States of America.] Improvements In Eyeglasses. I, Henry Harris Lake, of the Firm of Haseltine, Lake & Oo., Patent Agents, . 45 Southampton Buildings, in the County of Middlesex, do hereby declare the nature of this invention to he as follows :— This invention relates to eyeglasses and has for its object to make the eyeglass 5 adaptable to various noses or sizes of nose also to enable the eyeglass to be raised or lowered by sliding movement and these objects are effected by means of movable or adjustable nose pieces as more fully set forth in the following specification. The bow or spring serves to hold the glasses on the nose as known, and the glasses can be mounted in any suitable wav as in the rims or bezels, or the glasses 10 can be mounted without rims if desired. The arms or carriers support the nose ])ieces which can be constructed in any suitable way. A satisfactory nose piece is obtained by mounting a contact piece in a base piece, and making the contact piece of material suiting the touch of the wearer, as for example cork, celluloid or other substance. The base piece when made of metal will be strong and 15 durable. The arms or carriers are provided with dovetails or channelled portions and the base pieces are fitted to be slid or adjusted in said carrier portions. Springs exerting suitable friction or pressure will cause the nose pieces to be fixed against accidental displacement when suitably adjusted. By this arrangement the nose 2C pieces can be slid or adjusted to fit any nose or size of nose or the eyeglass can be raised or lowered as desired. The nose piece may be set at an * angle but of course the degree as well as the direction of inclination can be varied or if desired the nose piece can be arranged to lie in a plane with the glasses according to the requirements of the wearer. 25 The nose piece can be left free to be slid out of the carriers or if desired the base piece can be provided with stops on the base piece so that the nose piece while adjustable cannot be pushed out or removed from the carrier and security against loss is thus afforded. Of course the invention is not confined to the exact construction described as 30 modifications thereof can he made as for example the nose piece instead of being in two parts might be made of one piece. All such modifications are within the scope of my invention. To enable the nose piece to be fixed securely against accidental displacement, the. back or face of the nose piece contracting with spring can be toothed or made notched 35 or rack-like for firm engagement by the spring. The arms can be made rigid or springy, as desired, and by using spring or elastic arms the nose pieces can be made to sit easily or comfortably. Dated this 11th day of August 1896.
