' cation.

This invention relates to eyeglasses. The olbject of the invention is to provide means adapted to be interposed between the mounting brackets and the lenses so as to prevent breakage and permit the mounting to be screwed tight on to the lens. One object of the inventlon is to provide a lining or spacing member to cooperate with the mounting for the purpose set forth. Another object is to provide the lining or spacing member as an article of manufacture.

The invention will be more fully understood from the following specification read the accompanying drawing in which`v Figure 1 is a perspective view of a lining for eyeglasses embodying the invention;

1g. 2 is a sectional view on a large scale of a portion of an eyeglass lens and the mounting; and

Fig. 3 is a view of Referring to Figs. 2 and 3, the reference numeral 5 denotes the lens of an eyeglass and 6 the mounting. The latter is provided with a bracket portion 7 and two ears 8 and 9 between which parts a recess is formed to receive the lens 5 in the usual manner. The lens is secured to the bracket by a screw 10.

It is well known that the thickness of the lens is often less than the distance between the ears S and 9. Consequently the screw 10 must be screwed in very tight so as to bring the ears close to the lens aud very often the lens breaks because of the pressure required. It is also well known that the screw often becomes loosened because it has not been screwed in tight enough for fear of breakage.

The object of the invention is to provi-de means to overcome these diliculties. As seen in Fig. 1 the lining member for the mounting consists of an element in the form of a clip comprising a back 12 and two apert'ured ears 18 and 14. The lining member may be a portion of an eyeglass. Y

made of cardboard, paper, fiber, rubber, celluloid, or other similar or suitable material. The ears 13 and 14 are provided with a ) ertures 15 and 16 slightly smaller, prefera ly, than the holes 17 and 1,8 in the ears 8 and 9.

Vhen the lens is mounted the lining is laid within the mounting as shown in Fig. 2, the ears 13 and 14 corresponding to and fitting with the ears 8 and 9 and the several holes and apertures coinciding. The back l2 is laid against the bracket 7.

Thereafter the lens is placed in position and screw 10 screwed in. It will be seen that the lining takes up and fills the space between the lens and the mounting due to differences in size, and if the lens its .the

mounting accurately, the use of theA lining will cause the ears 8 and 9 to spring slightly apart. The screw may be. screwed in very tightly because the lining will give und'er the pressure and prevent the lens from breaking. And because the holes in the lining are slightly smaller than the holes in the ears of the mountings, the edges thereof will be caught by the screw as indicated at 20 and as the screw thus will be more firmly seated because of the softer material of the lining, the screw will not work loose as easily as 1t so often does.

` I have found the lining member to be very practicable, easy to use, it is practically invisible and materially assists in preventing breakage and loose screws in eyeglass mounting. i

I claiml. The combination with the lens and the mountingof an eyeglass, said mounting consisting of an edge bracket and opposed apertured ears,-of a lining member adapted to iit between said mounting and the lens and consisting of an edge memberand opposed integral ear members adapted to coincide with the ea rs aforesaid and having apertures slightly smaller than the aperture of the said opposed apertured ears.

` 2. The combination with the lens andthe mounting of an eyeglass, said mounting consisting of an edge bracket and opposedapertured ears, of a lining member adapted to fit between the said mounting and the lens and consisting of an edge member and opposed integral ear members adapted t0 coincide with the ears aforesaid and having apertures coinciding with the apertures in said eers.

3. As a new article of manufacture a lning member for eyeglass mountings consisting of an edge member adapted to lit the edge of the lens and, opposed apertured eer memo@ members bent at an angle to said edge member.

Signed at New York, in the county of 10 New York and State of New York, this fth day of April, A. D. 1918.
