9 Claims. (01. 88-53) This invention relates to the construction of eyeglass frames.

One of the objects thereof is to provide a device of the above nature in which the material is so I disposed as to attain a high degree of strength without heavy construction. Another object is to provide a device of the above nature in which the parts are securely held in assembled relation and yet conveniently taken apart. Other objects are to providea thoroughly practical eyeglass frame of attractive appearance, and one in which the obstruction to vision is reduced to a minimum. 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 which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the subjoined claims.

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

Figure 1 is a front elevation, certain parts being shown in a partially disassembled position;

Fig. 2 is a top plan view of the frame shown in Fig. 1, certain parts being cut away to disclose-the construction more clearly; and

Fig. 3 is a side elevation of the frame shown in Fig. 1.

Similar reference characters refer to similar parts throughout the several views of the drawins.

In this drawing there is shown at 10 a bridge, the end portions of which are downwardly extended, as at 11, and outwardly inclined to merge at their lower ends into the rims 12. As the construction is identical upon both sides of the frame, that on one only will be described. On the extension 11 is formed a guard arm 13 provided with a nose-pad 14, these parts being of any suitable detailed construction, but preferably having the guard arm of pliable material for purposes of adjustment.

One end of the rim 12 terminates in an end piece 15 to which it is secured, and which in turn is secured to or formed integral with at its other end the adjacent downward extension of the bridge. This piece 15 is preferably horizontal and slightly above the horizontal axis of the rim, thereby being somewhat inclined with respect to the adjacent portions of the latter. The remaining end of the rim is provided with an end piece 16 which rests upon end piece 15 and registers therewith while abutting against the adjacent portion of the bridge extension. With these end pieces thus positioned, the corresponding ends of the rim are in alignment, and there are provided, as indicated in dotted lines at 17, registering openings to receive a screw 18 threaded into the part 15 by which the rim is held in closed position.

By this arrangement for the end joint of the rim, 9. high degree of security is attained. m the first place, the inclination of the end pieces with respect to the radiusv of the rim imposes on the screw a stress inclined with respect to its axis if the rim tends to open, thus bringing into play the strength of the screw itself and not depending solely uponthe threads cut therein. In the second place, thesolid support of the end piece 15 at both ends, and the wedging of the end piece 16 into position between the bridgeand lens, give a partially interlocking relation which also coacts with the screw in holding the rim in 7 closed condition. a

At the outer portions of the rims 12 there are provided a pair of curved and members 19 which merge into or are formed integral with the rim at points respectively above and below its horizontal axis. These members 19 are curved not only in a vertical plane, as shown in Fig. 1, but in a horizontal plane, as shown in Fig. 2, and, at their outer point of connection one with the other 20, are spaced both to the rear as well as laterally out from the adjacent-lens. The portion 20 is slotted and has pivotally secured therein, as by means of the screw 21, the adjacent perforated endof the temple 22. This pivotal point, being positioned as shown, carries the temple itself further from the eye and shortens the necessary length of the temple, thus decreasing the leverage upon its pivot and permitting a temple of lighter construction to be used. Also, the rearward displacement of the pivotal point permits the temples to be folded readily into positions parallel with the planes of the lenses.

It is to be particularly noted that the end members 19, although sufllciently rigid to maintain the form into which they are placed, are nevertheless of such pliable nature that they may be manually adjusted when the frame is fitted. They may, for example, as shown in Fig. 2, be adjusted inwardly, as indicated in the dotted lines 23, or outwardly, if desired, so as to vary the dis- 105 tance between the temples without materially affecting the length ofthe temples or necessitating the bending of the temple bars. Furthermore, they may be adjusted upwardly or downwardly, as indicated at 24 in Fi 3, thus varying the in- 110 clination of the temple bars with respect to the plane of the lenses as desired. These adjustments, furthermore, may be readily accomplished without detracting from the symmetry and attractive appearance of the frame=as a whole.

By the above construction, not only are the above advantages achieved, but a high degree of visibility in all directions is attained. As indicated by the dotted lines in Fig. 2, throughout a substantial angle the opening formed by the members 19 permits unobstructed vision in a lateral direction without lessening the strength and rigidity of the connection between the rim and the ear-loop of the temple. Furthermore, and in a somewhat similar way, the open construction between the parts 11 and neighboring portions of the rim 12 gains a high degree of strength and stiffness and yet avoids obstruction of vision at this point. These features are particularly important in such relations as the driving of motor cars, in which even slight obstruction of vision is often dangerous.

It will thus be seen that there is provided a frame in which the several objects of this invention are achieved in an essentially practical manner without detracting from its appearance.

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 istobe 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.
