MOUNTING FOR SPECTACLES AND EYEGLASSES.

To (ZZZ 10710-722. it we (13 concern Be it known that I, CHARLES J. 'llnorrn'im, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Mounting for Spectacles and Eyeglasses, of which the following is a specification.

My invention relates to improvements in spectacle and eye-glass mountings which in their final form will comprise an integral piece of metal; and the objects of my improvement are, first, to simplify the construction of the mounting; and, second, to provide a single, simple member having facilities by means of which adjustments can be easily made to secure the fitting of the guards and glasses to all shapes and varieties of noses. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view or elevation of the metal before it is bent into a mounting; Fig. 2 is a top plan of the metal as it is in Fig. 1. Figs. 3, t, and 5 are top plans showing progressive steps in the formation of the mounting; Fig. 6 is a side view of the completed mounting; and F ig. 7 is a view of a modification in which a blank of the mounting is stamped from a sheet of metal.

Similar letters refer to similar parts throughout the several views.

The letter a designates a strip of metal which may be provided from sheet metal or wire. I prefer to use a slightly flattened wire of oval crosssection. To each end of the strip, a, are attached, by solder or other approved method, nose guards, b, 7), which extend at substantially right angles with the strip, a. At two points at suitable distances from the ends of the strip, a, are at tached lens securing means, each comprising the lens strap, 0, and the lens ears, (Z, (Z, which extend away from the strip, a, in a direction at right angles with the plane of the nose guards. It is obvious that this blank could be stamped initially from a sheet of metal if desired, as shown in Fig. 7; but I find that the bending operations, hereafter to be described, impart to the metal all the necessary temper which may have been withdrawn by the soldering oper' ations.

To form the mounting from the strip,

'' provided as above described, the metal is Specification of Letters Patent.

first bent into the bridge, (2, with the reverse bends, 7'', f, as shown in Fig. 3. This brings the lens straps in substantially proper position with relation to the bridge. The outer [)Olt'lOilS of the strip a, are now bent inwardly and rcarwardly to form the bends, y, as shown in Fig. 4:. As seen in Figs. 4, 5, and 6 the ends of the strip, a, pass under or over the bridge. The outer ends of the strip, are now bent. as shown in l ig. 5, to form the inwardly turned reverse bcnds, l1, 7:, having the guards, b, b, projecting forwardly from their ends.

I t is obvious that with integral mountings the length of metal must remain constant in the same mounting, and the problem is to supply the simplest facilities which may be manipulated to adjust without distorting it, or interfering with its functions.

With my mountii'ig it is evident that the pupillary distance, the forward and back position of the bridge, and the vertical angle of the bridge can all be adjusted by manipulating the bends, j", 7. These manipulations secure the positioning of the lenses and bridge in proper relation to the eyes and nose of the wearer, but do not provide for the attachment of the mounting to the nose. The facilities for adjusting the attachment to the nose are afforded through the manipulation of the bonds, 9, g, and it, h. The length of the nose guard arms, the height of the guards relative to the lenses, and the proximity of the guards to each other are secured principally through the manipulation of the bends, g, g, although these adjustments may be effected somewhat by manipulating the bonds it, it. The ad justment of the longitudinal positions of the guards themselves through all vertical angles is usually secured through the bends, Ii, 11, although this adjustment also can be eti'ected somewhat through the bends, g, g.

It is obvious that a considerable length of metal may be worked into each of the bends, g and h, to shorten the guard arm, when necessary, without making the mounting more cumbersome or alfecting its functions in any manner. It is further obvious that all of the twisting of the metal, resulting from bending the metal in two or more planes, falls in the several bends heretofore mentioned where they are neatly accon'lmodated.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A mounting for spectacles or eyeglasses comprising a strip, nose guards upon either end of said strip, and means for attaching lenses comprising one end of a lens strap and an ear extending laterally upon both sides of said strip from points intermediate its ends.

2. A mounting for spectacles or eyeglasses comprising a straight strip of metal, the central portion whereof is bent into a bridge with forwardly opening loops on each side, the strip being then looped back- Wardly and the extreme ends looped forwardly, lens attaching means projecting from the ends of the bridge loops, and nose guards carried upon the extreme ends of the strip.

3. A mounting for spectacles or eyeglasses comprising a bridge piece the ends of which are curved forwardly, then inwardly, and then backwardly to form loops, lens attaching means extending outwardly from the forwardly extending portion of said loops, and the inner ends of said loops being bent inwardly and forwardly and provided with nose guards.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

CHARLES J. TROPPMAN.
