Patented Dec. 31, 1929 UNITED STATES PATENT OFFICE ARTHUR IJL LEVY, OF BROOKLYN, NEW YORK, ASSIGNOR 'IO SUPERLOID MANUFACTUR- ING COMPANY, INC., OF BROOKLYN, NEW YORK, A CORPORATTON OF NEW YORK OE'H'II-IALMIC MOUNTING Application filed April 9,

This invention relates generally to ophthal mic mountings, particularly mountings wherein lens rings or frames, as well as the nose pieces therefor, are formed of non-metallic material; this application being a continuation in part of my application Serial No. 280,604, filed May 25, 1928.

As is generally known, at the present time non-metallic mountings of the type wherein the lens rings and bridge are formed in one piece require the dealer to carry in stock a large variety of sizes of such mountings in order to properly fit different types of faces. It frequently occurs, even where the dealer is possessed of a large variety of sizes of such mountings, that it is necessary to affix an extra piece on the bridge to especially adapt a mounting for flat noses. Again, difficulty is frequently experienced in adapting thegrips to the nose of the wearer so that proper positioning of the lens rings with respect to the eyes may be had without discomfort to the wearer. It is an object of the present inventionto provide an ophthalmic mounting of the type under consideration which is constructed in such manner as to overcome the objection common to similar types of mountings heretofore used.

The objects of the invention are carried out in the details of construction hereinafter set forth in the description and particularly specified in the claims, reference being had to the accompanying drawing, wherein Fig. 1 is a rearelevation of an'ophthalmic mounting of the type under consideration constructed in accordance with the invention,

Fig. 2 is a sectional view taken substantial ly upon line 22 of Fig. 1, the scale of drawing being slightly enlarged,

Fig. 3 is a detail view in section taken upon line 33 of Fig. 2,

Fig. l is a detail perspective view of one of the connectors employed in carrying out the invention,

Figs. 5, 6, 7, 8 and 9 are combined fragmentary elevations and perspective views illustrating various modifications of the connector for the lens frame an'dnose grip and illustrating their manner of application.

Referring now to the drawing, and particu- 1929. Serial No. 353,773.

larly to Figs. 1 to 3 inclusive, the lens rings or frames are indicated at 5, while the bridge connecting them is indicated at 6; the said ringsand bridge being continuous or of one piece and made of shell, horn, zylonite or other non-metallic material or-composition. In the present instance, the frames have associated therewith the hinged temples represented at 7, but it will be understood that the invention is equally applicable to mountings of the Oxford type.

The nose pads or grips for the mounting are indicated at 8, and are formed of nonmetallic material substantially similar to that of which the rings and bridge are constructed. The advantages of nose griips formed of such material are well recogniZed in the art, and it is to the manner in whichsuch pads are connected to the rings or frames that the present invention is directed.

The nose grips o1 pads 8 each have associated therewith a metallic connector 9 to afford connection between the nose grip andthe ring with which it is associated. The connectors 9 are formed of pliable or ductile metal, capable of being flexed to a great variety of positions or angles by the use of proper instruments, yet possessing sufiicient rigidity and resiliency to firmly hold the mounting upon the nose of a wearer. The metal is also of such nature as to create the desired retaining pressure in forcing the pads into contact with the nose without becoming permanently deformed.

Each connector is provided at one end with laterally and oppositely directed wings 10 to provide a relatlvely great area in that particular end of the connector. The said end, together with its wings, is embedded in the nose grip or pad 8 in the formation of the latter, so that when the grip has become set or hardened, the connector will be securely and firmly anchored therein. The opposite end of the connector is provided with similar wings or projections 11, each ofwhich carries a prong 12 disposed at right angles to the plane of the projection 11. These prongs are preferably disposed in parallelism. The connector for the greater part of its length is preferably of uniform width, and is bent upon itself intermediate its ends in substantially U-shape as shown. In the proper application of the connectors to the lens frames, the prongs 12 are embedded in the frames so as to securely anchor the same to the frame. \Vhen properly positioned, the body portion of the connectors will be disposed outwardly or in the general direction of the lenses carried by the frames.

In the modification disclosed by Fig. 5 of the drawing, the connector is represented generally at 9 and includes a flat pliable metal body of substantially rectangular formation with divergent prongs 13 at its ends to be embedded in the non-metallic nose pad 8 and lens frame 5 respectively.

In Fig. 6, the connector 9 has its ends pronged as shown, and these prongs have inwardly directed hooks or detents 14: to act as anchorages for the ends of the connector embedded in the nose pad and lens frame.

In Fig. 7 the connector 9. has its ends 15 deflected as shown so as to engage within the material of which the nose pad and lens frame is formed and to secure the ends firmly therein.

In Fig. 8 the same general type of connector 9 is shown, the ends being pronged and the extremities of the prongs having enlargements which constitute lateral deflections 16 to perform the function of anchorages.

In Fig. 9 the connector 9 has laterally deflected wings 16 at its ends, which wings have openings 17 through which retaining elements 18 may be passed to secure the ends 16 firmly with the material of which the nose pad and lens frame is formed.

\Vhen constructed in this manner, the connectors afford a great latitude of adjustment in positioning the nose grips. The adjustment of the body portion of each connector may be made with the use of opticians pliers or other grips, and due to the ductility of the metal of which these connectors are formed, lateral and longitudinal adjustments to even the most minute degree may be easily and quickly made. The optician is thus enabled to adapt a given mounting to the face of practically any customer. Lateral, longitudinal and angular adjustments of the nose pads may be easily made, and the mounting may be properly adjusted to the face notwithstanding irregularities or deformities in the nose of the wearer.

The several views of the drawing disclose a number of ways in which the pliable connector may be constructed to perform its purpose, and while the foregoing is a description of the invention in its preferred embodiments, it is nevertheless understood that strict limitation thereto is not implied as further variations in the detailed structure and assemblage may be made without departing from the scope of the invention as defined by the claims.

Having thus described my invention, I claim:

1. In an ophthalmic mounting, lens rings formed of non-metallic material, nose grips formed of non-metallic material, a connector formed of pliable metal uniting each nose grip with its respective lcns ring, and the ends of said connectors engaged in said lens rings and grips respectively.

2. In an ophthalmic mounting, lens rings and nose grips formed of non-metallic material, a connector formed of pliable material for each nose grip and lens ring, wings projecting from one end of each connector and embedded in the body of said nose grips, and the opposite ends of said connectors secured to said rings.

3. An ophthalmic mounting comprising a pair of lens rings and a bridge member formed in one piece and of non-metallic material, nose grips formed of non-metallic material, arms of pliable metal, each arm having laterally directed wings at one end embedded in the material of the nose grips, laterally directed projections at the opposite end of each arm, prongs extending at substantially right angles to said projections and parallel with each other, said prongs being embedded in said rings, and the intermediate portions of said arms being of substantially uniform breadth and bent into substantially U-shape.

4. In an ophthalmic mounting, lens rings, nose grips formed of non-metallic material, a connector formed of pliable material for each nose grip and lens ring, wings projecting from one end of each connector and embedded in the body of said nose grips, and the opposite ends of said connectors secured to said rings.

In testimony whereof, I hereby aflix my signature.

ARTHUR M. LEVY.
