SPECIFICATION forming part of Letters Patent No. 732,47 3, dated June 30, 1903.

I Application filed October 6, 1902.

To aZZ whont it may coir/007%.-

Be it known that LWILLIAM A.VESOELIUS, a citizen of the United States, residing at Hightstown, in the county of Mercer and State of New Jersey, have invented and produced new and original Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. I

The objects of this invention are to enable the nose wire or spring adapted to arch the nose and the shanks of the nose-pieces adapted to press against the opposite sides of the nose to be clamped together with increased firmness and security and without the weakening effects due to perforating the parts, as heretofore, and to secure other advantages and results, some of which may be referred to hereinafterin connection with the description of the working parts.

The invention consists in the improved eyeglassand in the arrangements and combinations of parts of the same, all substantally as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 is a front elevation of an eyeglass of my improved construction. Fig. 2 is a section of the same, taken on line x of Fig. 1. Fig. 3 is a sectional View taken at line y of Fig. 2,!on an enlarged scale, and showing the construction of the improved clamp or clip more fully. Fig. 4 is a sectional view taken at line z of Fig. 3; and Fig.5,is a view similar to Fig. 3, showinga modification in the construction of the clamping-screw.

In said drawings, a ct indicate the eye glasses or lenses; 1), the nose wire or spring c c, the nose-pieces, adapted to press against the opposite sides of the nose to hold the lenses thereto, and d d are the clips, adapted to fasten the said nose wire or spring b, the lenses a a, and the nose-pieces c c separably together. The portion h of each clip adapted to be attached to the lens may be of any Serial No. 126,018. (No model.)

'.usual construction, and the nose wire or spring I) and the nose-pieces c 0' may also be of any usual construction. The nose-Wire b is of flat wire bowed to extend over the nose, and the nose-piece shanks e e at their extremities are also of flat wire, as usual. The said shanks e and the opposite ends of the bowed spring I) are preferably of uniform width, so as to enter neatly between the jaws f f of the clip. Heretofore said fiat-wire ends have usually been perforated midway of their longitudinal edges and the fasteningscrews 2' extended through the jaws f and also through the ends of the perforated fiat wires, and the flat wires were thus very materially weakened, and in common practice they frequently broke where perforated. It has been proposed to insert the said ends in clips and clamp the same in place by means of screws, the said ends overlapping within the clips and the screws entering between to effect in various ways the desired clamping. By my method and means of construction I not only avoid perforating the ends, and thus weakening them, but my construction permits a very strong fastening of the parts without the necessity for much preliminary work in fitting the parts. With these ends in view I form the clip-jaws ff as shown in ,Figs. 3, 4, and 5, where said jaws are shown toextend perpendicular to the axial line of the shank g, connecting the said jawsff for the wires to the clip-jaws h,'between which the lens is secured. The said jaws ff are united at the front of the spectacles forward of the said axial line of the shank g, the connection is forming a bearing for the front edges of the flat wires and the free or separate ends of said jaws f f lying back of said axial line. Said jaws near the rearward extremities are perforated to receive the clamping-screw t'. I prefer to perforate the said jaws f f near the open ends thereof, so that the centers of the spaces between the lines of the centers of said perforations and the connec tions is lie in a line parallel with the axis of the shank g, the axis of the clamping-screw '5 lying back of the axis of the shank g, as shown in Fig. 3. Said screw 1' is disposed so as to enter notches (shown in Fig. 4) formed in the edges of the flat wires, so that the said fiat wires will not only be held against longitudinal withdrawal by means of the friction due to the clamping, but will be positively held against withdrawal because of the screw t lying in said notches. The screwt' is preferably of conical form at m, where it engages the edges of the said flat wires, and the edges of the wires are correspondingly formed, as indicated in Fig. 3, to be engaged by the incline surface, and thus by turning the screw to its binding relation the said conical surface of the screw impinges upon the edges of the fiat wires and forces the same against the fiat bearing 7; at the forward end of the slot formed between the jaws f, thus holding the said wires firmly against any possible pivotal movement, as well as clamping said wires together and to the clip against longitudinal withdrawal. Thus constructed it is evident that under some circumstances I can reduce the length of the shank g from what is ordinary, or I can fasten or form the jaws h it immediately against or on one of the jaws f without injury to the clip and sometimes to the benefit of the eyeglasses, especially as I am thus enabled under some conditions to secure a more proper adjustment of the focal centers of the glasses to eyes that are closer together than is usual.

I may countersink the larger perforations for the head of the screw tand form the conical surface of the screw so that it extends clear to the extremity of the head, and in that event the head of the screw will lie within the countersink flush with the outer side of the jaws f, which conduces to neatness of appearance, or I may form a flat head upon the screw and not countersink the jaw at its perforation, as shown in Fig. 5, so that the flat head will lie against the outer side of the said jaw, in which case a more durable construction is obtained.

Having thus described the invention, what I claim as new isl. The combination with the lenses, nose wire or spring and nose-pieces having shanks, of clips adapted to be fastened to the lenses, said clips each having jaws disposed transversely with relation to the longitudinal center line of the shanks adapted to receive the nose-wire and shank therebetween, said jaws each being perforated near its free end, and having a clamping-screw which extends from one jaw to the other in a direction parallel with the clip-shank and impinges on the edges of the nose-wire and nose-piece shank, substantially as set forth.

2. The combination with the lenses, nose wire or spring and nose-pieces having shanks, of clips adapted to be fastened to the lenses, said clips each having jaws adapted to receive the nose-wire and shank therebetween, said jaws being each perforated near its free end, and having a clamping-screw lying in the perforations of the jaws and said screw having a conical surfaceimpinging on the edges of the nose-wire and shank and clamping the nose wire and nose piece shank edgewise against the closed connection of the jaws and fiatwise against one another and said jaws, substantially as set forth.

3. In an eyeglass, the combination with the lenses, a notched nose-wire and nose-pieces having notched shanks, of clips adapted to hold the lenses, and having jaws arranged perpendicular to the plane of the lens, the ends of the nose-wire and nose-piece shanks being arranged between said jaws and screws arranged in the separate projecting ends of said jaws and entering the notches of the said nose-wire and shanks, substantially as set forth.

4. In an eyeglass, the combination with a lens, of a notched nose-wire, a nose-piece having a notched shank, a clip having jaws adapted to receive the lens and jaws arranged perpendicular to the first of said jaws to receive the end of the nose-wire and shank, the said jaws being connected and forming a hearing 70, said shank and wire being inserted between said jaws and engaging the bearing at one side and a screw impinging upon the opposite side of said wire and shank, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 25th day of September, 1902.

. WILLIAM A. VESCELIUS.
