EYEGLASS CONSTRUCTION Filed OGt. 1'7, 1934 Patented July 13, 1937 PATENT OFFIE EYEGLASS CONSTRUCTION George Nerney, Attleboro, Mass., assignor to Bay State Optical Company, a corporation of Maine Application October 17, 1934, Serial No. 748,574

5 Claims.

This invention relates to an eyeglass construction and more particularly to the connection between certain parts thereof.

' One of the objects of this invention is to pro- 5 vide a simple and thoroughly practical eyeglass construction. Another object is to provide a construction of the above nature having a minimum number of parts and capable of easy assembly. Another object is to provide construction of the above nature which may be readily and inexpensively manufactured in large quantities. A further object is to provide a construction of the above nature wherein certain parts may be readily disassociatecl for the purposes of replacement or repair. A still further object is to provide a construction of the above nature which is sturdy and durable under the strain of extended use. A still further object is to provide a construction of the above nature which is pleasing T in appearance and which may be comfortably Worn by the user. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combination of elements,

0 and arrangement of parts, as will be exemplified in the structure to be hereinafter described, and the scope of the application of which will be ine dicated 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 an eyeglass -mounting, certain of the parts thereof being broken away;

Figure 2 is a rear elevation of the mounting shown in Figure 1;

Figure 3 is a sectional elevation of the mount? ing taken along line 33 of Fig. 1.

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 inventionit might here be pointed out that in eyeglass frames or the like, and more particularly frames of the type in which non-metallic rims are associated with a metallic bridge, considerable difiiculty is experienced in providing a connection between the rims and the bridge. For example, due to the character of the materials it is difficult to obtain a joinder of the parts which will not loosen after continued'usagasuch loosening being difficult and sometimes impossible to correct. Further, in these constructions it is difficult to provide parts such as rims and bridges which may be readily interchanged after assembly without serious damage to one part or the other. Further difficulty is also encountered in providing a frame of the above nature which does not have certain fragile parts particularly susceptible to break- 5 age. Another object of this invention is to provide a construction of the above nature in which the above-mentioned difficulties, in addition to many others, are successfully and efliciently overcome.

Referring now to the drawing, there is shown a pair of rims generally indicated at l!) and II (Figures 1 and 2) and a bridge generally indicated at l2, rims l0 and l I being connected to bridge l2 in a manner hereinafter more fully described.

Bims l0 and l l are provided with enlarged portions l4 and I3, respectively, portions 13 and 14 preferably being integrally formed on the rims and preferably being shaped to form a pair of nose guards I5 and i6. Thus the nose guards include projections I50; and Mia extending rear- Wardl-y from the rear plane surfaces of rims l0 ll, preferably gbeing integral therewith and having their opposed surfaees substantially convex or rounded and neferably roughened so that they may rest firmly and cs rnfortably on the nose of the wearer.

As best shown in Figure 1, the tops of the rim portions I3 and 14 break sharply 'to gradually merge into the rims, thus forming in eifect shoulf ders i8 and Hi, the top surfaces of which are al-' most at right angles to the opposing surfaces of the nose guards, immediately behind each of projections lfaaand Ilia; proyide holes 2B and 35, respectively, extending through rim portions l3 a I4 and av n the r re unn ub ta al y p ee silll P9 t e P an Q ih e es mounted in the girns. Y

The upper portion 21 of the bridge member l2 may be arpuate in form {Figures 1 and 2) preferably extending from rim to rim. I'he opposite ends of the bridge thence extend inwardly and downwardly in effect forming the arm portions 22 and 23 resting snugly against the peripheries of the rims and preferably spread from the front surfaces la. and Ila thereof, as best shown in Figure 2. Immediately adjacent shoulders l8 and IS the opposite end portions bend rearwardly and extend in directions substantially perpendicular to the general plane occupied by portion 21 and arm portions 22 and 23 of the bridge (Figures 2 and 3) to form the rear extensions 24 and 25 which rest firmly upon shoulders l8 and I9, respectively.

Next, the ends of bridge 2! again bend sub stantially at right angles to the axis of rear extensions to form the leg extensions 26 and 21, as more clearly shown in Figures 2' and 3. Leg extensions 26 and 27 rest firmly upon the rear surfaces of rim portions 83 and M and are also preferably in engagement with the rear sides of projections l5a and Mia, thus being, in effect, adjacent the junction between projections Eta, and I612 and the rims of the frame. Leg extensions 26 and 21 extend downwardly, as viewed in the drawing, to points adjacent holes 25 and 35 where they bend again to form the fastening portions 28 and 29 which extend forwardly through the holes in a direction substantially perpendicular to the plane occupied by leg portions 26 and ing the fastening portions firmly in position,

while allowing for removal therefrom should the necessity arise.

The particular shape of bridge 2! and the portions thereof in engagement with rims l6 and I I, all as described above, make for an extremely practical and firm connection between the bridge and the rims. In practice, frames of this general character are often subjected to considerable rough usage which is particularly damaging to the points of connection between the various parts. For example, the rims are often twisted, thus to strain the points of connection between the bridge and the rims. Where the rims are formed from non-metallic material and the bridge from metal, these connections are often the most vulnerable spots on the frame. However, due to the particular shape of bridge 29, the connection between the bridge and the lens is re'enforced regardless of the strains, as, for example, twisting, exerted on the frame.

If, for example, the rims are spread outwardly, portions 22 and 23 abut against the peripheries of the rims thus guarding against any damaging relative movement between the bridge and the rims anywhere in the vicinity'of holes 20 and 35. Again, if rim H is twisted forwardly about its transverse axis, as viewed in Figure 1, rear extension 25 abuts against shoulder i9 while leg portion 26 abuts against the rear face of rim Ill, both of these portions of the bridge tending to offset any forces exerted in the vicinity of the holes 26 and 35. Other strains exerted on the bridge and rim connections of my frame would be materially offset by corresponding portions of the bridge in engagement with portions of the rims. The fact that bridge 2i comprises so many individual portions running in so many different directions to remain in close contact with the irregular portions of the rims located about the nose guards I5 and 56 thus makes for a firm and durable connection between these parts of this frame.

It will thus be seen that I have provided a thoroughly practical, eflicient and durable construction in which the several objects described above, as well as many others, have been successfully achieved.

As many possible embodiments may be made of the above invention, and as many changes to the plane of said rims.

may 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.
