EYEGLASS CONSTRUCTION Filed Aug. 12, 1941 BY a ATTORNEY Patented Mar. 28, 1944 UNITED STATES PATENT OFFICE f EYEGLASS CONSTRUCTION George E. Nerney, Attleboro, Mass, assignor to Bay State Optical Company, Attleboro, Mass, a corporation of Maine Application August 12, 1941, Serial No. 406,459

7 Claims.

This invention relates to eyeglass frame construction.

One of the objects of this invention is to provide an eyeglass frame which is simple, thoroughly practical, and durable in use. Another object of the above invention is to provide a construction of the above character, the manufacture of which will be economical both from the standpoint of labor and materials used. Another object is to provide a construction of the above character which will be neat and attractive in appearance. Another object is to provide a construction of the above character the strength of which is greatly increased due to the durability and lasting quality of the more vulnerable portions thereof. A further object is to provide a construction of the above character which is particularly adapted to absorb the shocks and strains resulting from extended use. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing in which is shown one of the various possible embodiments of this invention,

Figure 1 is a front elevation of the eyeglass frame;

Figure 2 is a top plan view of the construction shown in Figure 1;

Figure 3 is a horizontal section, on an enlarged scale, taken on the line 3-3 of Figure 1; and,

Figure 4 is an exploded perspective view, on an enlarged scale, of portions of the frame shown in Figures 1 and 2.

Similar reference characters refer to similar parts throughout the several views of the draw- As conducive to a clearer understanding of certain features of this invention, it might here be pointed out that in the construction of a metal rim frame the bridge and its points of connection to the rims are known to be one of the weakest portions of this type of frame. This is caused by the fact that it is very difficult to produce a bridge which will be sturdy and securely attached to the rims and yet be light in weight. Also, when a frame is in use, and the lenses are twisted or are forced out of the positions in which they normally lie, the strains must be absorbed by the bridge. To withstand these strains, bridges are very often made of heavy construction. This type of bridge is liable to cause increased lens breakage, however, as it lacks resiliency and thus does not absorb shocks resulting from striking the ends of a frame. The force of these shocks, if they are not absorbed by the bridge and evenly distributed throughout the frame, very often results in lens breakage.

It is another object of this invention to provide a construction in which the above-mentioned. difiiculties, as well as many others, areovercomea It might here be noted that reference here-- inafter to an outward direction signifies a di-- rection to the right or the left of the center-ofthe bridge of an eyeglass frame in the direction of the temple, while the term inward denotes;

a direction toward the center of the bridge from one of the temples.

whereas the term forward denotes the opposite direction thereto.

Referring now to Figure 1,there is shovvnaframe having a pair of metal rims I0 and II completely encircling and holding inposition a pair of lenses l2 and I3. made of any suitable construction and are split at points I4 and I5 (Figure 1) through endpieces I6 and I1 in order that the lensesmay 'be dis-- posed therein. Screws l8 and I9 (Figure 2) hold the split rims in assembled're'lationship, and a pair of temples 20 and 2! are pivotally connected to endpieces l6 and I! in any suitable manner,

such as by screws 22 and 23.

The bridge,'generally indicated at 24, includes. a metallic bridge member, generally indicated at 25, and a non-metallic bridge member, generally indicated at 26. The metallic member 25 is' preferably made of a resilient metal and is of flat.

ribbon-like construction (Figures 1 and 4). -Substantial portions of the outer ends of this mem ber are connected to the upper edges of rims Hi" and l l in any suitable manner, such as by'solder." As is best shown in Figure 1, rims l0 and H ex positioned immediately below metallic bridge A rearward direction -refers to a direction toward the face of a wearer,

An upward direction refers to a direction upwardly from the face of a wearer while a downward direction is opposite there-.

Rims Ill and may bemember 25, includes a center portion 2! and a pair of depending portions 28 and 29. The center portion 21 extends between the rims and has sections 21a and 21b (Figure 1) which extend outwardly into the pockets between the metallic bridge member and the rims described hereinabove. Depending portions 28 and 29, which are integrally formed with portion 21, taper downwardly and outwardly to meet rims l and II (Figure 1). Extending rearwardly from depending portions 28 and 29 is a pair of nose pads 30 and 3| (Figures 2, 3, and 4) which preferably have their inner surfaces in curved planes which extend through the inner edges of depending portions 28 and 29. The outer edges of the nonmetallic bridge member are preferably grooved (Figures 1 and 3) to receive the portions of rims I0 and I I they contact.

To connect non-metallic bridge member 26 to the frame, a pair of U-shaped straps 32 and 33 is provided. These straps extend over the metallic bridge member, bridging the sides of the pockets formed between the member and the rims, and have their free ends secured to the front and rear edges of rims l0 and H in any suitable manner, such as by soldering. To mount the non-metallic bridge member the rims are spread, and the outwardly extending sections 21a and 21b are introduced into the pockets between the rims and the metallic bridge member. When the rims return to their normal position, the pockets, straps, grooves on the outer edges of the non-metallic bridge member, and shape of the non-metallic bridge member all coact to retain the non-metallic bridge member in assembled relationship with the frame. To more securely connect the non-metallic bridge member to the frame, screws 38 and 39 (Figures 1 and 4) may be used. These screws extend through holes in one of the legs of each strap through the outwardly extending sections 2142 and 21b of the non-metallic bridge member, and then are threaded into the other leg of each strap. Thus, it may be seen that the straps both serve to reenforce the connection of the rims to the metallic bridge member and also are of material importance in mounting the nonmetallic bridge member on the frame.

Thus, a frame has been disclosed in which the resilient metallic bridge member permits a maximum of movement of the various parts of the frame with respect to each other. Furthermore, the non-metallic bridge member forms an efficient buffer between the rims and thus is particularly well adapted to absorb the shocks which result when an end of the frame is struck against an object. It will thus be seen that I have provided a thoroughly efficient and practical construction in which the several objects hereinabove referred to, as well as many others, are successfully accomplished.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
