MOUNTING FOR ORNAMENTS Filed May 22. 1930 lllllllll Patented Sept. 13, 1932 vireo .T orrie leAr MOUNTING non ORNAMENTS Application filed May 22, 1930. Serial No. 454,642.

This invention relates to an improvement in the construction of ornamental articles, such as buckles and the like, and has particular reference to. articles having motheri of-pearl ornaments mounted thereon.

Mother-of-pearl plates or ornaments have been difficult to mount so as to entirely conceal the fastening means. My prior patent No. 1,547,738 shows one manner of accom- 1 plishing this result, but this construction has the disadvantage that heat is necessary to fuse the holding solder, this heat causing the delicate mother-of-pearl to crack, and also undesirably changing the color. in addition, the use of solder necessitates a deep recess, thus requiring thick ornament stock; the deep recess unduly weakens the stock and prevents utilization of a relatively thin stock.

The principal object of my invention is to 29 provide a simple and effective fastening method which does not require the application of heat. An additional object is to provide a fastening method which permits use of thin ornament stock.

A further object of my invention is to utilize a deformable rivet, the ornament being shaped to facilitate the locking action of the rivet, and to entirely conceal the rivet.

With these and other objects and advantageous features in view, the invention includes the novel method and the novel structure more fully described in the detailed description following, in conjunction with the illustrative drawing, and more particularly specified in the appended claims.

In the drawing: 7

Fig. 3 is an enlarged section on the line 33 of Figure 1; V

Fig. 4 is a section through an ornament blank;

Figure 6 and Fig. 8 is a section showing the final looking of the ornament to the backing plate.

It has been found desirable'to provide a mounting for mother-of-pearl and other fragile ornamentsthatdoes not require a great I amount of pressure, and that does not require tli the application of heat. I have therefore devised a'meth'od and a structure for mounting such ornaments, which utilizes. an undercut recess in the ornament to receive a rivet made of soft, ductile material, the recess having a convex base which spreads the rivet base outwardly'into engagement with the undercut wall of the recess; and the following is a detailed description of the preferred manner of-forming the parts and mounting theornam-ents. f

Referring to the drawing, the buckle or other ornamental article 10 has a base plate 11 on whichone or more ornaments 12 are mounted, the base plate being preferably shaped to conform to the outline ofthe ornaments, and the mounting of the ornaments, as. indicated in Figure 3, being entirely concealed from view from thefront.

Each ornament 12 is recessed as shown in Figure 4:, the recess 18 having a convex base 1 1 and an undercut peripheral wall 15. A rivet 16, shown in section in Figure 5, is blanked out of ductile material, and includes a conical upper portion 17 and a cylindrical shank 18, the base 19 of the rivet being indented, as at 20, to facilitate the final riveting operation. The edge of the conical portion 17 is preferably cylindrical, as indicated at 21.

In assembling, the rivet is inserted in the recess'lS, and the conical portion 17 is forced flat, thus causing the cylindrical edge to spread and to enter the corner between the undercut wall and the base of the recess and lock the rivet in the recess. The shanks 18 of the thus mounted rivets are then inserted into rivet openings 22 in the base plate, and are then pressed inwardly, thus distorting the rivet so as to tightly lock the plate and the ornament. The convex base of the recess prevents curling of the edge 21 by guiding the inner portion of the rivet'shank outwardly.

- This construction therefore locks the ornaments to the base plate without solder, without the application of heat, without showing the mounting at the front. In addition, the construction requires only a shallow recess which does not unduly weaken the ornament stock, and therefore permits the use of ornaments formed of very thin stock. While I have described and illustrated a specific manner of mounting the ornaments, desired changes in arrangement and in details of construction may be made without departing from the spirit and the scope of the invention as defined in the appended claims.

I claim: v

1. In combination, a base plate having an opening therethrough, a mother-of-pearl or= nament having a recess in the back thereof, said recess having a convex base and an undercut peripheral wall, and a cup-shaped holding member of ductile metal having an integral bottom wall closing one end and an open end, said open end flared into locking engagement with said recess and its shank end extending through said opening and enlarged over said base plate.

2. In combination, a base plate having an opening therethrough, a non-metallic ornament having a recess in the back thereof, said recess having a convex base and an undercut peripheral wall, and a cup-shaped holding member of ductile metalhaving an integral bottom wall closing one end and an open end, said open end flared into locking engagement with said recess and its shank end extending through said opening and enlarged over said base plate and having said bottom wall bent inwardly.

In testimony whereof, I affix my signature.
