Patented June 25, 1907.

Ap li ati n filed February 27.1905. Serial No. 247,519.

The sections referred. to are preferably U To all whorlt 1125 may concern:

Be it known that I, PAUL MoEws, residing at Detroit, in the county of Wayne and State of Michigan, a citizen of the United States, have invented certain new and useful Improvements in Mountings for Eyeglasses or Spectacles, of which the following is a specification, reference being had therein to the accompanying drawings The invention relates to a novel type of mounting applicable for either spectacles or eyeglasses, and capable of use in connection with standard types of lens fittings whereby it may be conveniently and easily applied to glasses in gen'eral use.

Among the several objects of the invention is the production of a universal and inconspicuous mounting, light in weight and so engage the nose of the wearer at the proper point.

Another object is to so construct the mounting that it may be manufacturedat minimum cost without waste of material and a further object is to so fashion the mounting that axial deviation of the glasses will be practically prevented, thus adapting the mounting for cylinder or prismatic lenses.

WVith these various objects in View, the invention consists in the novel construction of the mounting as hereinafter set forth, and in the peculiar arrangement and combina tion of its parts.

In the drawings illustrating my invention, Figure 1 represents a section of wire from which the mounting blank is preferably made. Fig. 2 designates a shaped blank. 3 is an illustration of the blank with the metal flattened. Fig. 4 is an enlarged View taken on line 11 of Fig. 3. Fig. 5 is a perspective view of the completed mounting. Fig. 6 is a View in rear elevation thereof. Fig. 7 is a sectional perspective View of a modified form of mounting, and, Figs. 8 and 9 are respectively detached sectional and perspective views, showing the application of the modification to the lens.

Referring to Fig. 5 of the drawlngs, A rep resents the finished mounting, comprising complementary attaching sections B, B, a curved bridge or nose piece 0 connecting the sections and extending forwardly therefrom at an acute angle; D and Dthe guards and E,

or channeled-shaped in configuration, the channels opening in the direction of the guards, as illustrated. The vertically disposed uniting portions (1 of the channel sections may be fitted within suitable boxes for the lens, in which instance they are apertured as at b to receive the binding screw, or they may be provided with studs 0, as indicated in Fig.7, to be used for spectacles or eye-glasses where the boxes of the fitting are omitted, as indicated in Fig. 8.

By shaping and positioning the attaching sections in the manner set forth, I am enabled to lower the bridge into the position occupied by the usual saddle bridge of spectacles, making the bridge as inconspicuous as possible, and, at the same time, increase its length to prdvide the necessary resiliency. The lower transverse portionsdof the attaching sections, in extending into proximity to the guards D, D, bring the complementary members a and b of the depending loops E and E into edge contact, thereby forming a wide fiat bearing acting in conjunction with the guards as additional or auxiliary bearing surfaces to hold the mounting securely upon the nose of the wearer.

-The mounting is made preferably from a flat strip of metal preferably formed from wire, as will be more fully hereinafter described, and the several turns and bends formed therein to produce the attaching sections, guards, etc., are made edgewise of the metal, so that in the finished mounting each attaching section with its guard and connection lies substantially in a common plane, these planes being parallelly arranged and perpendicular to the plane of the lenses. This construction as will be obvious from an inspection of Fig. 5 of the drawings permits of the ready engagement of the attaching section within the ordinary box (not shown) of a lens fitting, and also brings the flat face of the metal forming the guards and connections in contact with the nose of the wearer, whereby a maximum gripping surface for the mounting is obtained. It will also be noticed that by forming the mounting so that the sections thereof are in parallel planes, with the exception of the bridge .or nose piece, only the edge of the metal is exposed to view, and as the nose bridge is in angular relation to the lenses only a relatively small portion is exposed so that the mounting as an entlrety is inconspicuous.

I am aware that mountings have been made heretofore from flat metal strips, but these have been necessarily stamped out of sheets necessitating more or less waste of metal, or else made from flat strips bent in planes transverse of the face producing cumbersome and unattractive 'inountings. have obviated these defects by making the various turns or bends necessary in the plane of the face of the metal as previously set forth to give the attractive and inconspicuous appearance desired, and to obviate the straining and stretching of the metal necessarily resulting in bending flat strips in this manner and the consequent production of brittle mountings, I form. the latter from wire in a manner presently to be described.

The reference letter F (Fig. 1) represents a section of wire of metal that will not rust, usually 10 to 14 carat gold, or German silver. By suitable means, the wire strip is first bent with a minimum amount of strain, into the desired form of blank, as indicated in Fig. 2, the central portion in this instance being straight while the end portions are fashioned to form the channel shaped attaching sections, the guard sections and the connecting loops, previously described. The blank thus formed is then heated to an extent as to anneal the metal, so that such slight strains as have been necessarily imposed upon the blank during the operation of bending Will be taken out of the bent places, leaving the wire uniform throughout. If studs are to be used as a part of the mounting in place of the boxes, they are attached to the annealed blank, the construction of stud preferably employed be ing that shown in Fig. 7, the inner end of the stud being split and the members 0 and c bent in opposite directions at right angles to the stud proper, so that when applied to the mounting, a maximum amount of bearing surface will be obtained. These stud sections are secured to the mounting preferably by a solder of the same tenacity as the mounting metal, so that in the operation of flatten ing, the stud sections willbe united with the mounting, making them practically integral therewith.

By suitable dies, the shaped blank, with or without the studs, is flattened, thus producing the flat metal construction desired, and at the sametime restoring the temper to the metal, so that the mounting will have the required resiliency. The flattened blank is then curved or bowed centrally in a plane transverse to the plane of its face, which may be readily done without straining, and

normal conditions.

the desired shape of mounting produced. The guards and auxiliary bearings may then, if desired, be bent slightly out of the com mon planes in which they lie, to conform generally to the configuration of the nose of the wearer. Preferably, the finished mounting is heated slightly, to set the temper, so that the mounting while having the necessary resiliency, will retain its shape under The operation of setting, while not absolutely essential, is desirable as it produces a more serviceable fitting.

What I claim as my invention is:

1. A single piece flat metal fitting for eyeglasses or spectacles, comprising channel shaped attaching sections parallelly arranged in planes perpendicular to the plane of the lenses, a bridge member joining the upper inner ends of the channel section and project ing forwardly at an acute angle therefrom, upwardly extending guards offset from the attaching sections and bridge, and closed depending loops connecting the lower ends of said attaching sections and guards.

2. In eyeglasses or spectacles, a mounting comprising a bridge member, upwardly extending guards, and intermediate loopshaped attaching sections projecting for wardly from the bridge, the members of each loop extending rearwardly in relation to the lenses, and being connected respectively at their ends to one of the bridge ends, and an adjoining guard.

3. In eyeglasses or spectacles, a singlepiece fitting consisting of a bridge, loopshaped attaching sections having their complementary members extending rearwardly of, and in a plane substantially perpendicular to, the lenses, the upper members of the loops being connected to the bridge ends, forming a continuation of the bridge, and complementary guards secured to the ends of the lower members.

4. In a mounting for eye-glasses or spectacles, the combination with a bridge member, of forwardly projecting loop-shaped attaching sections at the bridge ends, studs upon said sections extending longitudinally of the bridge, and guard members extending upwardly and offset rearwardly from the attaching sections.

In testimony whereof I afiix my signature in presence of two witnesses.

PAUL MOEWS.
