10 Claims.

This invention relates to a nose pad for an ophthalmic mounting and has for one of its objects to provide a non-metallic covering over a metallic body which covering will be securely held in desired position.

Another object of the invention is the provision of parts so shaped that they will be locked together by reason of the method by which they are assembled.

The invention also consists in the method of bending one of the parts to permit the insertion of another part in a recess formed therein and then the return bending of the part so deflected or distorted to a desired finished position which will maintain the parts in locked relation.

' The invention further consists in the method of locking the parts together by undercutting one part and providing a projection on another part to extend therein, which parts are assembled by the distorting of one of the parts to permit the entrance of the other part therein.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a front elevation of a fragmental portion of eye glasses with rims and showing nose guards as mounted in the relative position which they assume with reference to the lens and bridge connecting them.

Fig. 2 is a perspective view of one of the finished nose guards with an arm projecting therefrom.

Fig. 3 is a perspective view of the metallic portions of the guard of the structure shown in Fig. 2.

Fig. 4 is a section on line 4-4 of Fig. 2.

Fig. 5 is a plan view looking at the inner surface of the non-metallic portion of the guard alone.

Fig. 6 is a central sectional view of the guard with a recess formed in an inner surface thereof.

Fig. 7 is a view similar to Fig. 6 showing the recess undercut.

Fig. 8 is a sectional View showing the cover as flexed or bent for the insertion of the metallic portion shown in Fig. 3.

Fig. 9 is a sectional view of the metallic portion inserted and the covering bent back.

Fig. 10 is a perspective view of the guard mounted on one of the arms which secure it to the bridge or lens holder.

It is found desirable in the use of nose guards to provide a non-metallic covering for engagement with the nose and in order that such cover 2 covering to spread the edges of the recess I am en-' abled to insert the metallicv body into the recess with its flange in the undercut portion and then by bending the covering back into the desired finished plane, move the overhanging stock" on the edge wall of the recess over the flange tosecure it in position; and .the following is a detailed description of the present embodiment of this invention illustrating the preferred means and method by which these advantageous results may be accomplished.

With reference to the drawing, 10 designates one lens and 11 the other, each provided with. a lens holder 12 which may take the form of a rim as here shown. A bridge 13 suitably connects th lens holders, and nose pads 14 are secured to the bridge or lens holder in any desired manner.

The nose guards or pads each consists of a body 15 of generally oval or elliptical shape which is provided with a flange 16 flush with the front face 17 -thereof, while from the inner face 18 there extends an arm 19 which may be suitably secured to a support for the pad. The cover 20 is preferably formed from some non-metallic material such as celluloid or the like and is recessed at 21 in the first step in the operation as shown in Fig.6, after which by a further step an undercut 22 is provided in the wall 23 of the recess as illustrated in Fi 7.

In order that the cover 20 may be secured to the body member 15 I heat and bend or deflect the cover as shown in Fig. 8 to spread the walls 23 of the recess in which deflected position the body member 15 may be set into the recesswith its flange 16 in a position to extend into the undercut portion 22 of the recess, after which, by again bending the cover 20 back to substantially a single plane as illustrated in Fig. 9, the stock 24 forming the margin of the recess or opening 21 extends over the inner surface 25 of the flange and securely locks the metallic body 15 in position. In bending the cover back to form a single plane, heat is applied which so softens the marginal edge 24 as to cause a portion 26 thereof to extend over the body itself and further lock the metallic body in the cover as illustrated in Fig. 4.

Any suitable pad support may be provided, such as an arm 2'7 having an enlarged flat portion 28 with an opening to receive the arm 19 which may extend therethrough and be headed over as illustrated in Fig. to rockingly support the pad in permanently adjusted position.

The foregoing description is directed towards the method and construction illustrated, but I desire it to be understood that I reserve the privilege of resortingto all the equivalent changes to which the construction and method are susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A nose pad for an ophthalmic mounting, comprising a body having-{an outer face and an inner face, an arm secured toand extending from the inner face of said body, a flange of a thickness less than said body extending laterally from said body and about tl'ielp'er iphery thereof and a covering over the outer face of the body and extending over the inner surface of said flange tolock the covering on said body.

' 2. A -nose'p'ad for an" ophthalmic mounting, comprising abody having an outer face and an inner face, an arm secured to and extending from the inner face of said body,a flange of a thickinner face, an arm secured to and extending from theinner face of said body, and a covering over said outer face of the body and extending over the inner surface of said body in a lesser area and in a thickness greater throughout its extent than the thickness of the covering on the outer face of said body, whereby to provide sufficient strength of covering over the inner faoe'to prevent removal of the body from the covering.

4. A nose pad for an ophthalmic mounting, comprising a body having an outer face and an inner face, an arm secured to and extending from the inner face of said body, a flange of a thickness less than the thickness of the body extending laterally from said body about, the periphery thereof and flush with the outer face and forming a shoulder at the inner surface, and a covering over said outer face of the body and flange and extending over the-inner surface of said flange to said shoulder to lock the covering on said body.

5. A nose pad for an ophthalmic mounting, comprising a metallic body having an outer face and an inner face, an arm secured to and extending from the inner face 'of said body, a flange of a thickness less than the thickness; of the body extending laterally from said body about the entire periphery thereof and forming a shoulder at the inner surface, and a non-metallic covering over said outer face of the body and extending over the inner surface of said flange to said shoulder to lock the covering on said body.

6.
