Application filed December 0, 1980. Serial No. 152,854.

This invention appertains to spectacle frames and it has particular reference to means for reinforcing the nose-bridge and temple-bars of such frames.

One object of the invention is to provide an improved method of reinforcing an ophthalmic mounting. which shall be superior to the slow and tedious,-inconven1ent as well as inaccurate steps hitherto employed in strengthening the bridge and temple pieces of spectacle frames.

Another object is to roduce a reinforcement of the nature set orth, capable of being expeditiously and advantageously incorporated in an ophthalmic mounting during its process of manufacture.

A further object is the production of a 'means of the type specified particularly.

adapted to reinforce nose-brid es and temple-bars of spectacle frames ma e of genuine and imitation tortoise-shell or analogous substances, still leaving the mottled or streaky markings occurring in the latter undisturbed.

A still further object is to furnish a re inforcement of the species mentioned, appli cable to ophthalmic mountings, without the necessity of drilling or forcing a hole through the same by means of a heated wire.

A still further object consists in roviding a reinforcement of the kind re erred to,

- which when secured within the members of an ophthalmic mounting, not only permits of the same being bent to conform to the contours of the wearers head, but that will also serve to retain the conjoined reinforcements and members in the various shapes imparted thereto.

An additional object is to supply a reinforcement of the classalluded to, composed of a minimum of simple parts, readily placed in their assigned positions, besides amenable to low cost of manufact re.

Other objects and advantages of the invention will becomeapparent as the specification proceeds.

With the aforesaid objects in view, the invention consists of the novel combinations and arrangements of scribed in their pre erred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

arts hereinafter de-.

Briefly described, the invention under consideration includes in its organization a piece of wire of approved material, size and length, constituting the proper. This wire is lodged upon the bottom of a groove or channel of greater depth than the thickness of the reinforcement, itself, and cutv longitudinally of the roughened-out nose-bridge and temple-bars ertaining to 'the blank of an ophthal inic mounting made of real or artificial tortoise shell. A sealing strip preferably composed of a like substance to the aforesaid nose and temple parts, is secured by means of a suitable cement in the groove over the wire. The strip spoken of, fills the groove completely, retaining the before named reinorcement in place therein. The finishing operation performed on the frame in ques tion, removes surplus or projecting portions of the sealing strip, making the same flush with the exterior surfaces of the parts referred to. The latter can be bent or offset to fit the nose and side of the wearers head, the reinforcements within the bridge and temple parts mentioned, keeping them in the shapes imparted thereto.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in the one and same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, upon becoming conversant with the detailsthereof, that the same may be incorporated in several different constructions. 'The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.

In the said drawing:

Fi re I is a front view of a blank from whic the lens frames of an ophthalmic mounting is made, the manner of reinforcinthe nose bridge thereof being shown;

ig. II is a section taken on the line IIII of Fig. I, looking in the direction pointed out by the arrows;

Fig. III is a fragmentary section and edge view of an ophthalmic mounting, illustrating particularly the reinforcement of the bridgeiece and one of the temple-bars;

Fig. V is an enlarged section on the lines reinforcement Ill IV-IV of Figs. I and III, looking in the direction of the thereto appertaining arrows; and

Fig. V is also a front-view of the lens frames, corresponding to Fig. I, representing the same in completed condition.

Referring now to these several views for a detailed description of the invention thereby exemplified in one of its preferred embodiments, it will be observed that the known parts of an ophthalmic mounting wherewith this reinforcement is associated and coacts have been designated by letters of reference, instead of numerals as are used to denote the present improvement. This was done it will be understood, merely to intimate that the said parts are not treated or considered as pertaining exclusively to the latter but are claimed herein only so far as they form therewith legitimate eombinations of elements capable of yielding novel and useful results.

Of these reference letters, A identifies a roughened out blank from which the lens frames of an ophthalmic mounting is formed. A blank of this character may be composed of either genuine or imitation tortoise shell, such as any of the ordinary celluloid compositions. The blank A comprises spaced apart lobes B conjoined by a connecting piece C and having lugs D projecting outwardly beyond the lobes oppositely to said connecting plece. Out of the lobes B arecut the lens rings or rim members 13 (Fig. V), havin the usual internally bevelled lens seats B Fig. HI). From the connecting piece C is formed the nose-bridge C the lugs D when dressed down to their proper size, constituting the ears D to which hinges E for temple bars F are secured, as is common practice.

In order to introduce the reinforcement where required in the nose-bridge, the blank A is first clamped down flatwise on a suitable machine table, and then a groove or channel 11 is milled for a certain depth, in a longitudinal direction through the middle of the connecting piece C This groove extends preferably into the solid portions of the lobes B, far enough to afford a straight or level hearing or seat in the bottom thereof for a reinforcing element 13, to rest on. The latter may consist of any suitable material, but by preference a low carbon steel wire is used therefor. Notwithstanding that a reinforcing element of square section has been indicated in Fig. VT, it will of course be understood that a wire of any other approved configuration may be employed in its stead. The thickness of the reinforcing element is selected normally to be about half the depth of the groove 11, while in width it fills the latter. The aforesaid element 13 is of a length somewhat shorter than the distance between the adjacent inner faces of the rims 13', so that there will be no danger of the ends of the wire coming into contact with the edges of the glass lenses to cause injury or possible fracture of the same.

With the object of retaining the wire element in its assigned position, a sealing strip 15 is lodged in the groove 1 over and upon the wire therein. The seal referred to, is to a certain extent, made longer than tne wire 13 which it completely covers. At such times as the lobes B are hollowed out to produce the rim rings B those portions of the strip 15 which project within the channels 11., beyond the inside margins of the said lens frames, indicated by dot-and-dash lines I) in Fig. I, are also cut away. It does not make any difference that a small interstice is left at each end of the groove in question, i. e. between the interior face of the lens seats and the terminals of the reinforcing wire. As a general rule, cement of a suitable kind is employed in the reinforcen'lent receiving channel, both to imbed the wire element 13 therein, and for causing the sealing strip 15 to adhere to the sides of the said groove 11. For the strip mentioned, the same material of which the blank A consists, can be used, or if desired, some other substance, of a different color,

may be substituted, in order to obtain a variant effect. It will be seen that by virtue of the groove 11 cut into the side of the lobe-connecting-bridge B, the wire element 13 is not surrounded entirely by this bridge, the strip 15 being a separate sealing and filling medium. At 17 is indicated a thin covering preferably composed of the same material as the mounting, being cemented over the sealing strip to the same side of the nose-bridge C The covering referred to, serves as an additional safe-guard to hold the sealing strip 15 from coming out of the groove 11, and also to prevent the latter from opening up when the bridge is subjected to bending or twisting stresses.

For the temple bars, one whereof is shown at F, Fig. HT, the same method is followed in strengthening these as in reinforcing the nose-bridge. A channel 11 is grooved in the side of the said bar F, while the same is in the flat or straight condition, depicted by dot and dash lines at 7. The odset F occurring at the free end of the aforementioned bar, can be formed therewith, either before or after the reinforcing element 13 and the sealing strip 15 are placed in their assigned positions. Obviously, if the end of the temple-bar is set-01f as at F before lodging the wire and seal in place, the last named parts must also be made to conform in advance to the shape imparted to the said bar. It stands to reason that if needed, coverings like 17, can be applied to the sides are incorporated with the nose-brid e and temple-bars, the same may be bent urther by the optometrist, fitting a particular formation of human head to which the ophthalmic mounting is to be applied. The wire element in question will always tend to retain the bridge and temple members in the shape they were last given. It is also clear, that with proper fixtures, a groove or channel like those illustrated, namely 1111, can be cut in the bridge B and bars F, more accurately and. expeditiously, than it would take a small and delicate drill or heated wire to pierce thru a like distance of material. Insertion of the reinforcing element 13, and cementing of the thereover superimposed sealing strip 15, can readily be performed by less costly and, skilled labor than what would be required for either drilling or burning. Such portions of the sealing strip which project beyond the outermost edges of the reinforcement receiving channel can quickly be dressed off.

Wh1le a certain preferred embodiment of this device has been shown and described, it will-be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made, without departing from the scope of the invention as defined by the ap ended claims.

Having descri ed my invention what I desire to secure by Letters Patent and claim,

1. The method of reinforcing an ophthalmic mounting, which consists in forming a channel in the member thereof to -be strengthened, lodging a piece of reinforcement material ofless t ickness than the depth of said channel against its bottom, and securing a sealing strip of substantially the same width as the said channel in the latter covering the reinforcement therein.

2. The method of'reinforcing an ophthalmic mounting which consists in cutting a groove in a member of the mounting to be strengthened, placing a reinforcement wire of approximately equal width'but less thickness than the depth of said groove against the bottom thereof, and cementing a sealing strip in the said groove completely filling the latter over the reinforcement therein.

3. A method of reinforcing an ophthalmic mounting which consists in machining a. groove lengthwise of a member of the mounting to be strengthened, inserting a wire of shorter length and approximately half the depth of said groove therein, cementin a strip of like material to the member wit in the said groove to seal the latter over the wire insertion, and dressin off projecting surplus stock from said strip to conform the same to the contours of the member. p

4. An ophthalmic mounting including a member having a channel formed therein, a reinforcement of less thickness than the depth of said channel lodged upon the bottom thereof, and asealing strip of substantially the same width as the said channel secured in the latter over said reinforcement.

5. A member for an ophthalmic mounting comprising a piece of material having a groove cut therein, a reinforcin wire of approximately equal width but Ease thickness than the depth of said groove placed against the bottom thereof, and a sealing strip cemented in the said groove filling the latter over said reinforcing wire.
