12 Claims.

The present invention relates to nose guards for ophthalmic mountings, particularly nose guards comprising non-metal material, and to methods of making the same.

An object of'the invention is to provide a new and improved nose guard that shall have essentially the flexibility, softness and other characteristics of the non-metal material, but shall nevertheless be reinforced to compensate for the weakness of such non-metal material.

Another object is to provide a new and improved method of making nose guards.

Other objects will be explained hereinafter and will be particularly pointed out in the appended claims.

The invention will be explained in connection with the accompanying drawing, in which Fig. 1 is a rear elevation of an ophthalmic mounting embodying the present invention; Fig. 2 is a plan 20 of the same; Fig. 3 is an enlarged section taken upon the line 3-3 of Fig. 2, looking in the direction of the arrows; Figs. 4 and 5 are views, corresponding to Fig. 3, of modifications; Fig. 6 is a section taken upon the line 66 of Fig. 3, looking in the direction of the arrows; Figs. 7 and 8 are views of further modifications; and Figs. 9, 10 and 11 illustrate steps in the manufacture.

The ophthalmic mounting of the present invention comprises a one-piece bridge comprising a bridge proper 2 and guard supports 4, each support 4 having an opening 6 into which fits a rivet 8 carried by a nose guard or rest 10. The rivets are headed over, as shown at 12, so that the guards may be secured on the guard supports 4 with a universally rocking motion,

Each guard or nose rest 10 is composed of some non-metal material, like celluloid, unbacked by any reinforcing or supporting member, such as metal. Each guard 10 is provided with an opening 14 extending, in the direction of the thickness dimension of the guard, from the outer face 16 to the oppositely disposed inner face 18 of the guard. The thickness distance between the oppositely disposed

faces

16 and 18 is, of course, small compared with the dimensions along said faces in the direction of the length or the width of the nose rest. The rivet 8 has integral therewith a metal member 20 that is inserted in the opening from the face 18 substantially to the face 16 of the guard. The parts are rigidly secured together, thus forming an integral, onepiece, unbacked non-metal guard, except for the metal portion 20.

If desired, the metal portion 20, instead of extending horizontally across the guard, as shown in Figs. 1 to 6, may extend vertically thereof, as shown at 22 in Fig. 7, or it may have a zig-zag appearance, as illustrated at 24 in Fig. 8, or it may have any other desired shape. Various configurations for the

metal

20, 22, 24 may be employed, both for appearance and also to help to support and reinforce different parts of the nonmetal guard 10. In all cases, of course, the opening 14, into which the metal is received, extends over a distance, in a direction along the

faces

16 and 18, that is of substantial extent compared with the dimensions of the guard, so as to provide for the use of a substantial amount of metal which is of corresponding extent. The metal may be secured in its opening 14 in any desired manner. For example, the member 20 may be tapered outwardly from its inner face 21 to its outer face 23, as shown in Fig. 6', and the ends thereof may be recessed or concaved, as shown at 25 and 27, and the non-metal material forced into the recesses.

Instead of forcing the non-metal material into the recesses 25 27, it is preferred to upset the metal over against the non-metal walls of the opening 14. A preferred method is illustrated in Figs. 9, 10 and 11. A metal blank, as illustrated in Fig. 9, having

opposite faces

23 and 21, is slipped into the opening 14, with the pronged, rivet portion 8 projecting therebeyond into a die 30. A plunger 32 is then caused to descend against the .85 face 23 of the metal blank, thereby forcingsharppointed edges 34 of the die 30 into the face 21 and upsetting the metal and forcing it outwardly. The metal near the face 23 tapers slightly inward, and a similar taper is produced by this upsetting operation near the face 21, with the result that the metal blank is rendered of greater width near each of the

faces

21 and 23 than between the faces, thus producing the concaved faces 25 and 27.

Other methods may also be employed to fasten the parts together, though the described method has been found to eliminate all possibility of the parts becoming accidentally separated, either forwardly or backwardly. The pronged, projecting rivet portion 8 is later inserted into the opening 6 of the guard support 4, and headed over at 12, as before described.

In some cases, it is desirable to have the metal stop just short of the face 16 of the guard, as illustrated at 26 in Figs. 4 and 5, whereby the metal is depressed below the face 16 of the guard.

In this manner, the skin of the nose may be kept out of contact with the metal. Indeed, if desired, the depression at 26 may be filled in, as shown at 28 in Fig. 5, and this may be done in any desired way as by applying a thin layer of celluloid either in solid form or in the form of a liquid, in the latter case permitting the liquid to dry and harden.

Other modifications will occur to persons skilled in the art and all such are considered to fall within the spirit and scope of the invention as defined in the appended claims.

What is claimed is:

1. A guard comprising an unbacked non-metal nose rest having an opening of substantial extent compared with the dimensions of the nose rest and extending fro-m one face of the nose rest to near the opposite face of the nose rest, a metal support for the nose rest having a portion of corresponding extent disposed in the opening, whereby the said portion is depressed below the said opposite face, and a non-metal filling in the depression.

2. A method of making a guard comprising providing a non-metal nose rest with an opening extending from face to face of the nose rest, inserting a metal member in the opening from one face to near the opposite face of the nose rest, whereby the member is depressed below the said opposite face, applying a liquid layer of the nonmetal material in the depression, and permitting the liquid layer to harden.

3, A method of making a guard comprising providing a non-metal nose rest with an opening extending from face to face of the nose rest, inserting a tapering metal member in the opening from one face to near the opposite face of the nose rest, upsetting an intermediate portion of the metal member into the non-metal nose rest, in-

sorting the smaller end of the metal member in an opening of a nose-rest support, and upsetting the said smaller end of the metal member to secure the metal member to the nose-rest support.
