7 2,362,726 n a MOUNTING MEANS FORYSPEQTACLES David Slotsky, Cleveland,0hio Application May 31, 1941, Serial No. 395,903 8 Claims (01. 88-47) My invention relates to the fastening of a mounting of a spectacle to the lens of the spectacle. My mounting is for use in fastening the nose or bridge piece to the lens, for use in fastening the temple or ear piece to the lens, and for fastening any other type of mounting to the lens, in all cases where the mounting is to be secured, fastened or engaged in conjunction with a fastening hole providd in the edge of the lens.

An object of my invention is to provide a secure and adequate mounting for a lens which will not become loose. To those acquainted with the art, it is also well known that when the mounting becomes even slightly loose, the play between the lens and the mounting tends to induce a fracture of the lens. i

The nature of my mounting is such that it cannot become loose after it is once permanently connected.

Another object of my invention is to provide a simple and eflicient means for the fastening of my mounting to the lens. My mounting is easily insttalled and requires little skill in assembling the par s. r

Another object of my invention is the provision of a mounting for a lens which accommodates lenses of different thicknesses.

Another object of my invention is the provision of completely filling the fastening hole on the edge of the, lens so that there is no opportunity for the mounting to become loose and develop play with respect to the lens.

Another object of my invention is the provision of an arm connected to a strap member for embracing the side edge of the lens in which the arm is substantially invisible.

Another object of my invention is the provision of compressing a softpliablesleeve into the fastening hole of the lens in order to completely fill the fastening hole and thereby prevent any play in loose movement between the mounting and the ens.

Other objects and a fuller understanding of my invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawing, in which:

Figure 1 represents a lens of a spectacle to which my mountings have been applied, both to the nose piece and the ear piece;

Figure 2 is a view of a lens of a spectacle to which my mounting has been applied to the nose piece only;

Figure 3 is aview of a lens of a spectacle to which my mounting having an invisible arm for embracing the side edges of the lens has been applied to both the nose piece and the ear piece;

Figured is an enlarged andfragmentary view of a lens illustrating the first step of mounting a soft metal sleeve in the fastening hole of the lens; Figure 5 illustrates a view similar to Figure 4 but with the soft metal sleeve cut back to a length substantially equal to the thickness of the lens; Figure 6 represents'a side elevational view of a fragmentary portion of a strap having a round shoulder and a screw secured therein;

vFigure 7 is a View illustrating the arrangement of the parts when the mounting of Figure 6 is inserted in the fastening hole of the lens of Figure 5; i

Figure 8 is across-sectional view of my finished mounting; I

Figure 9 is a view similar to Figure 8 but shows the screws being mounted in the reverse direction to that shown in Figure 8;

Figure 10 is a perspective view of my mounting having laterally extending arms from the strap portion which when mounted upon the lens appear substantially invisible; and

Figure 11 shows a front view of the mounting in Figure 10 secured to the edge of a lens.

With reference to the drawing, my mounting is indicated generally by the reference character I i tening hole I 8 in the marginal end thereof. Thus,

my mounting is adaptable for all cases where the mounting is to be secured, fastened, or engaged to the lens, in conjunction withthe hole provided therein. i Y I My mounting comprises a strap member !3 having a round shoulder portion [4 secured thereto which is adapted to fit closely in the fastening hole I8 for a 'distance less than the width of the lens.

As illustrated, the round shoulder portion I4 is providedwith a female threaded opening to receive a screw l5 having a threaded portion l6 and a head 11. The strap member I3- is countersunk so that the head I I of the screw fits almost flush with the outside surface of the strap member I3. The threaded portion l6 of the screw extends be yond the shoulder, portion [4 and is arranged to project through the fastening hole l8 of the lens. The combination of the shoulder portion M and the threaded portion [6 of the screw l5 may be referred to as a post construction.

Mounted in the fastening hole I8 and positioned around the threaded portion 16 of the screw it is a soft pliable sleeve 2| capable of flowing under compression. In practice I find that a sleeve made of lead proves very satisfactory. For good results, the pliable sleeve 2i should be of such character as to flow or readily change its form under compression as distinguished from a metal sleeve which is hard or brittle. In production the soft metal sleeves 2.1 are made as long as the width of the thickest lens. As shown in Figure 4, the softmetal' sleeve,

2| is mounted in the fastening hole I8. of the.

lens and then the portion which extends beyond the upper surface of the lens is cut back flush with the lens as shown in Figure 5. The next step is to take the mountingin Figure 6 and in-' sert it into the fastening hole It of the lens as shown in Figure 5 which when finally inserted the partsitake the position as shown in Figure '7. The lower end. of the; soft metal sleeve 21 in Figure '7 abuts against the shoulder portion l4 and the other end. of the'soft metal sleeve 2'l" extends above the surface of'the' lens. The final step in securing my mounting to the lens is to threadably' turn a nut 22 upon the upper end of the threaded portion IE. As the nut 22' is turned down, it abuts against the upper end of the soft metal sleeve and compresses same there'- under against the lens and against the shoulder portion in the fastening hole around the threaded portion It to make a good firm connection between the post construction and the lens. The soft metal sleeve'as' it is compressed flows into all parts of the fastening hole t8" and completely fills the same to make a good firm connection without any play. The upper end' of the soft metal sleeve as the nut 22 is beingturned down flares outwardly underthe nut 22 andflows over the outsidesurface of the lens around the marginal edge of the fasteninghole- ['8 see Figure 8. Also, some of the soft metal of the sleeve flows down between the round shoulder portion H and the inside edge of thefastening hole [8 to fill all I possible clearances between the shoulder portion I4" and the inside'surface of the fastening hole IS. The soft metal of the sleeve 2lalso flows completely around the threads of the threaded portion I6. The ultimate result'is that a good firm connection i's-mad'e between the: post construction and the lens so that there is no opportunity for any play-to initially start between the post construction and; the fastening hole ['8 of the lens. In addition, ther v is no. tendency for the nut 22- tobecome loose; asitis: firmly em.- bedded in the soft metal sleeve andthus; the tendency to become loose. is: not. present.

In Figure 9 I illustrate how the screw [5 and the nut. 22 may be. mounted in the reverseorder from that. shown in- Figure. 8. In: Figure 9 the soft metal sleeve 21 is firmly compressed into the fastening hole of the lens by the head I! of the screw and the nut 22v is: threadablyengaged to the threaded portion Id of thescrew and abuts againstthe outside. surface. ofv the strap member I3. In Figures 8 and 9, after the nut 22 is tightly turned down upon thepthreaded -por-' tion I 6, the exposed end of the threaded portion I6 is cut back and made smooth and flush with the top surface of the nut 22.

In Figures 3, 10 and 11 I show an added pro"- vision mounted on my strap member l3 which comprises a laterally extending arm 23 for embracing the side edges of the lens to keep the mounting from turning with respect to the lens. The laterally extending arm 23 extends away from the strap member l3 on both sides thereof and forms two narrow lateral portions 24. The outside edge of the narrow lateral portion 24 is indicated by the reference character 25 and in my invention the outside edge 25 is substantially in alignment with the outside edge 26 of the lens, see Figures 3 and 11. On the end of each narrow lateral portion 24 is provided a. tab 21 which extends upwardly and engages the outside edge of the lens 26 at spaced distances from the strap member H. The narrow lateral portions 24 are relatively thin and lie on the rear side of the lens nearthe edge thereof. Under actual observation; the. narrow lateral portions 24 appear substantially invisible. The invisible nature of the narrow lateral portions 24 appears to result from the fact that'they lie in rear of the lens and near the outside edge thereof which positions them in a region coming under the reflection of the side edge portions of the lens so that an observer cannot see the-marginal lateral portions 24' so well as they-could be seenif they were located a substantial distance away from theoutside edge of the lens; The tabs 21 are relatively small and harmonize with the invisible character of the marginal lateral portions 24: of the arm 23'. That is to say, the construction of my armarrangement 23takes advantage of the reflection resulting from. the side edge surfaces of the lens in the region of the mounting. Although I have described my invention with a certain degree of particularity, it is understood that the present'disclosur has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed. 3
