VINCENT BERTOLINI, OF CHICAGO, ILLINOIS, ASSIGNOR TO F. A. HARDY &: CO.', OF CHICAGO, ILLINOIS, A CORPORATION.

LENS-MOUNTING.

Specification of Letters Patent.

Patented May 8, 1906.

To all whom itmay concern:

Be it known that I, VINCENT BERTOLINI, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi- 5 nois, have invented certainnew and useful Improvements in Lens-Mountings, of which the following is a specification.

The subject of the present invention isa lens-mounting which with slight variations nllay be used for either eyeglasses or specta- 0 es.

The invention relates more particularly to that class of mountings in which the post comprises two horizontal arms and a transversely-disposed portion connecting them and forming the inner end of the post and in which the straps proceed outward from said arms, respectively.

One object of the invention is to provide a mounting of the class described improved with respect to the construction and relations of the post and straps.

Another object is to provide such a mounting improved with respect to the construction and relations of the post, straps, and bracing-tongues.

Another object is to provide a mounting having a post of the class described improved with respect to the means for carrying the spring and guards.

A mounting made in accordance with the invention may be used in the construction of either eyeglasses or spectacles. When used in the construction of spectacles, the post may be without a box and the bridge may be attached in any desired manner. When used in the construction of eyeglasses, it may have a box integral with the post, or it may be without a box as an integral part, and a box of any desired construction may be attached. Again, it may be without a box and with the shank of the guard, or with the spring, or with both the shank and spring integral with the post.

Such terms as vertical, horizontal, top, bottom, &c., used in this specification are to be taken as relating to the position of the glasses when in use and with the lenses in a vertical or substantially vertical plane. Furthermore, mathematical accuracy is not intended or essential, and approximations or var ations which do not alter the device functionally are within the scope of these and other terms.

I am aware that it is not broadly new to make an eyeglass-mounting comprising a post, straps, bracing-tongues, and box from a single sheet-metal blank, and therefore desire to have it understood that the present invention consists in the features of novelty that are hereinafter described with reference to the accompanying drawings, which are made a part hereof, and in which Figure 1 is a front elevation of a pair of eyeglasses having mountings embodying the invention. Fig. 2 is a perspective view of one of the mountings. Fig. 3 is a diagram of the blank from which the mounting is formed.

Fig. 4 is a perspective view of a mounting embodying the invention with the box omitted. Fig. 5 is a front elevation of a modification.

A represents the lenses; B, the straps; C, the posts; D, the boxes; E, the guards; F, the bracing-tongues, and G the spring.

The post consists of two parallel arms 1, which are disposed one above the other, with their broader sides horizontal and a transversely-disposed portion 2 connecting the arms and forming the inner end of the post. The straps join the respective arms upon opposite sides of the post through the medium of bends 3, which bring their broader faces into vertical planes, while the broader faces of the arms of the post occupy horizontal planes. The bottom side of one of the straps is straight and in the plane of the lower arm, and from this plane the strap extends upward. The other strap is similarly constructed, but extends downward, so that the two straps lie between the projected planes of the two arms and are directly opposite each other, being provided with alined perforations for receiving the lens-screw. The end 2 of the post forms, also, the bottom of the box, (where the box is integral with the post) and its sides 4 consist of parallel flanges which join the vertical front and rear edges, respectively, from.

The bracing-tongues F are integral with the arms which they join, respectively, upon opposite sides of a vertical plane cutting'the of said end and extend inward therelens centrally. I am aware that it has been proposed to form the bracing-tongues of flanges which proceed horizontally from the substantially vertical sides of extensions proceeding upward and downward from one of the straps; but this is not the equivalent of this part of my invention, which is limited to tongues proceeding upward and downward from the post and join the post only at their extremities, thus leaving them free to be bent.

The mounting is formed of a single sheetmetal blank of the form shown in Fig. 3, the parts of the blank which form the several parts of the mounting having similar reference characters. In order to form the post, the blank is bent at right angles upon the lines 5, so as to bring the portions 1 parallel. The sides of the box are formed by bending the blank at right angles upon the lines 6, so 'as to bring the portions 4 parallel. The blank is slit, as at 7, so as to provide the portions B and F, the former of which are bent or twisted at 3 in opposite directions to bring their main portions into positions with their broader faces parallel and opposite to each other, thus forming the straps, while the portions F are bent in opposite directions and away from each other at the inner ends of the slits to form the bracing-tongues.

In Fig. 4 I have shown the mounting without any box, while in Fig. 5 I have shown (at each side of the mounting) the shank e of the guard and the end of the spring joining the opposite sides of the end of the post edgewise and proceeding in opposite directions therefrom, respectively.

I believe myself to be the first to provide a lens-mounting having a post comprising parallel arms and a transversely-disposed end connecting the arms and portions proceeding edgewise in opposite directions from the opposite sides of said end and serving to connect the spring and guard to the postand straps proceeding outward from said arms. I also believe myself to be the first to provide a mounting having a post and straps constructed as described and bracing-tongues proceeding upward and downward from the post.

What I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a lensmounting having a post comprising a pair of parallel arms located one above the other, and a portion connecting them and forming the inner end of the post, a pair of straps proceeding outward from said arms, respectively, and a pair of bracing-tongues directly joining the outer extremities of the arms and proceeding upward and outward therefrom, substantially as described.
