7 Claims.

This invention relates to the'method of makinga finger ring, and particularly that type of ring commonly known as an all metal or stone ring used extensively with fraternal, school or class emblems imposed thereon, and is a-continuation in part of my Patent'No. 1,947,254, issued February 13, 1934, for Method of making a finger ring.

The principal object of theinvention is to producearing'of this general character which is formedof-two diiferent metals, usually gold and silver insuch manner as to give the desired weight, appearance, thickness and wearingqualities-while-enabling the cost of the'm-aterial to be substantiallyreducedi It has been common practiceto form'rings with-a base of cheaper metal,

such assilver, upon which a gold facing; of suf ficient thickness to provide wearing qualities, is secured by soldering or fusing. It is the purpose -of 'this invention, however, to utilize this principle-in: constructing a ring with a silver filling which may have a solid goldfinger band.

O'nefeature of the invention resides in the formation ofa surrounding wallin the formed blank 1 in whichthe filler is embedded.

Another feature resides in the covering ofthe exposed surface of the filler: with a gold or preci'ouametal'plate providing an overlay so that no partofthe filler will be exposed, but will beentirely embedded within the enclosing structure,

of precious metal.

Another feature of 'the'invention resides'in'the formation of. the several pieces and their assembly: while the structure is in a substantially fiat: or extended form. before being bent into' circular orring-like formation.

The full nature of the invention: will be understood from the accompanying drawing andthe following description and claims:

portion formed therein for receiving the. filler. isa. perspective view'of the filler blank. Fig. 3:i's aperspectiveview'of theoverlay blank; Fig. 4 isz'a composite" perspective viewshowing the finger band. and. filler: blanksafter being formed andi the overlay blank positioned to be laid thereover. Fig. 5. is a perspective View of a. centralvertical-section through the composite blank'withithe. filler-and overlay in place before forming: the; ring. Fig. 6 is a perspective view of a section through the formed ring. Fig. 7 is a perspective-view of a section showing a modified. form: wherein the filler is placed upon an unrecessed fingerband blank. Fig. 8 is a similar In the drawing, Fig; 1 is'a perspective view-of a fingerband' blank. having a recessed central view of the form shown in Fig. 7 after being struck: Fig. 9 is a similar view of the structure shown in Fig. 8 showing an overlay blank covering the, entire finger band blank.

Inthe drawing there is illustrated in Fig. 6 a section through a fingerring having a finger band II), a crown I I upon which an emblem or the like may be mounted, a filler piece I2 and an overlay I3. The finger band, crown and overlay are of precious metaLsuch as gold, whereas the filler piece I2 isofa baser metal, such as silver. The invention herein described contemplates a ring ofthis character formed either with or without the overlay I3; Wherein the overlay is employed, the filler isentirely inclosed so as not to be exposed; Thus, the ring has the appearance and wearing v qualities of a. solid gold ring. Wherein the overlay. l3gis'eliminated, a portion of the filler IZJwill be exposed but will be on the inner surface of; they ring so that itis hidden from view when the ring is Worn.

'Ihefirst step of one of the methods, as illustrated in Fig. 1,,contemplates the provision of a substantially flat blankhaving extended arm por- 25 tions. IOa which eventually form the finger band II]. Intermediate said arm portions there is a central recessed portion I4 where the metal is cut away toreceive thefiller I 2.

In forming the blanks, whereas they are herein 30 illustratedas being flat, it will be appreciated that they maybeslightly curved or extend slightly in different planes without departing from the fundamentalrequlrement of the method. Such fundamental requirement isthat the blank be sufiiciently flat in formto be conveniently stamped or struck either before or after the filler is secured thereto. This procedure permits of an emblem or. design I 5 to bestruck on the sides of the finger band' blank while in its substantial fiat form.

As illustrated. in. Fig. 2, there is a filler piece I2. shapedto conform substantially with the recess i l-but smaller in area so as to leave an appreciable margin about the edge of the filler for the purpose hereinafter described.

In Fig. 3 there is illustrated an overlay I3 formed of precious metal which is thinner than the filler I2, and of such area as to overlap the filler I2 and extend to the edges of the finger band blank shown in Fig. 1. 50

After the formation of the above blanks, the finger band and filler blanks may be stamped either separately or together in a suitable die to provide a formed recess E la in the finger band blank with shoulders I6 and a curved crown por- 55 tion I la, the recess G; to be surrounded by walls H. The filler piece 12 is thereby formed to provide central portion Mb corresponding in contour to the formed portion Ida, so as to seat and fit snugly therein surrounded by the struck-up walls l1. Thus, the filler forms an inlay completely surrounded by the precious metal with its upper or exposed surface smooth and flat to receive the fiat overlay blank l3. The assembly may be viewed in cross section as illustrated in Fig. 5. The composiite blank is then bent into shape to form the ring illustrated in Fig. 6.

The same results are secured by stamping or striking the finger band blank separately from the filler blank in the same die and then fitting and securing them together. However, the more practical method is to lay the filler blank upon the finger band blank and either temporarily or permanently secure them together and then strike or stamp them. Either method will result in the form illustrated in Fig. 5, but the former method eliminates the requirement of a male die member. A fiat die block may be used, the filler blank performing the service of a male die member. It is immaterial as to whether or notthe filler blankisformed separately from the finger band blank as illustrated in Fig. 2. The same results are accomplished wherein the metal of the filler blank comprises a soldered or otherwise secured inlay in the finger band blank. However, it is preferable to follow the above method wherein the filler blank I2 is of less width than the corresponding portion of the finger band blank. This permits of the surrounding exposed surface of the filler blank being formed up into the walls I! so as to completely embrace the filler.

In the modified forms illustrated in Figs. '7, 8 and 9, the method may be followed wherein the finger band blank -I0ll-is not recessed as at I4. The filler blank H2 may be laid upon the blank Hill which is of the same thickness throughout. These blanks may be struck separately or, more conveniently, as above described, they may be struck together, the filler blank thereby taking the place of a male die. The result is, as illus trated in Fig. 8, that the unrecessed finger band blank is formed to provide the curved recess I la with the design or emblem H5 formed thereon a to provide the concave cavity for recessing the thickened filler blank I I2. Here, again, it is immaterial as to whether or not the filler blank is temporarily or permanently secured to the surface of the finger band blank. Fig. 9 illustrates the same with the gold overlay H3 extending from end to end of the finger band blank. This maybe preferable wherein, with this modified method, it may be desirable to reduce the thickness of the finger band blank. Such reduction in thickness may, therefore, be compensated for by extending the overlay blank H3 throughout the full length thereof.

From the foregoing, it will be observed that the blank with the filler formed to shape with the design or emblem l5 and the thickened recessed crown portion while in substantially flat extended form which permits of the ready formation of the ring thereafter with the fiat crown portion for receiving a superimposed emblem or stone. This is accomplished by stamping the blank and filler either separately or while secured together in the samerdie, the filler being entirely surrounded by the preeious metal of the blank. In

addition thereto, the filler may be entirely enclosed by the addition of the overlay blank to provide precious metal over the interior surface of the ring.
