INVENTOR RAYMOND Gv LUTRARIO ATTORNEYS ADJUSTABLE FINGER RING OF TWO UNI'IARY PIECES BACKGROUND OF THE INVENTION Finger rings which are adjustable for size of the finger have been heretofore known but are usually of such a character that the adjustment of the shank for size is very obvious from looking at the ring, such as in the U.S. Pat. No. 291,150, or if attempts have been made to hide the adjustment, then complicated tooling is necessary because of the more intricate construction and certain special wire must be used to provide increase thicknesses in parts of the shank and other complicated arrangements such as in US. Pat. No. l,169,735.

SUMMARY OF THE INVENTION This invention has a cast setting of any of many different shapes, sizes or thicknesses and a separate simple wire attached thereto such as by means of a reees back in which the two overlapping end portions of the shank may fit, with one portion secured to the setting fixedly while the other portion is slidable over the first portion to provide for adjustment of different sizes. Both of the overlapping ends of the shank are concealed beneath the setting so that the adjustment of the ring is hidden.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the finished ring;

FIG. 2 is a side elevation;

FIG. 3 is a section on line 33 of FIG. 2;

FIG. 4 is a section on line 4-4 of FIG. 3; and

FIG. 5 is a perspective exploded view showing separately the shank with its overlapping portions and the underside of the ornamental setting showing the recesses provided therein.

DESCRIPTION OF THE INVENTION An ornamental setting designated generally and shown in section in FIGS. 3 and 4 is a casting and may be of any shape or thickness desired. By way of example, there is illustrated a larger stone set in the mid portion of the ornamental setting designated generally 11 with a circlet of smaller stones l2 surrounding the large central stone to provide the ornamental portion of the top thereof although various shapes and sizes may be had. The inner surface 13 of the setting is generally arched and smooth and from this surface there extends two recesses. The first recess 14 is the deeper and narrower of these recesses and it is stepped as at 15 to provide a wider and shallower second recess. These recesses both open into the inner surface of the setting and there is a closure 16 at one end of this recess, while the opposite end of the recess is open as at 17. (See FIG. 4.)

The shank generally designated 20 has its band portion 21 in generally the form of a circle with overlapping

end portions

22 and 23. These

end portions

22 and 23 are of different widths. The inner portion 22 has been struck so as to thin this portion and also widen it.

The width of this end portion 22 is substantially the width 'of the recess 15 as shown in FIG. 3 and the thickness of the end portion 22 is substantially the flfiii'lfilll: 25522 lift filil rlfia otir't rifi? stantially the inner portion of the setting and will be flush with the surface 13 of the setting. The recess 14 will be a little larger than the width and thickness of the end portion 23 of the shank which overlaps the portion 22 and will be sufiiciently larger so that the end portion 23 may slide easily within the recess portion 14, the illustration in FIG. 3 showing this in somewhat exaggerated relation.

The thinned and flattened end portion 22 will be soldered in its recess 15 in order to hold it securely in position although other forms of fastening may be used. However, the end portion 23 may be expanded or contracted in order to provide the size desired for the ring. There will be sufficient stiffness to the shank 20 so that after the size has been acquired mechanically or on some sort of a ring arbor, it will maintain this size until further adjustment is had.

By reason of this construction a simple piece of wire may be struck to widen its end portion and the ring may then be assembled with some sort of a casting, which may vary in a wide degree, by merely fastening this widened shank portion into the setting and the ring is complete. No complicated tooling or intricate design is necessary. Two simple parts, a casting and a wire, are all that is needed.

Iclaim:

I. A ring formed of two assembled pieces of metal, one said piece being integrally formed of one piece of material and comprising an ornamental setting having a radially inwardly opening channel recess in its inner surface with said recess opening out through one end of the setting in a direction circumferentially of said ring and partly closed in said direction at the other end of the setting, said second piece consisting of a shank member integrally formed of one piece of material, said shank member being of generally circular shape and having overlapping radially inner and outer end portions located in said recess with the inner of said portions closing the inwardly opening recess and the remaining portion of the said other end thereof and the outer of said portions extending through the opening out of the recess through said one end of the setting, means securing the inner of said portions in said recess while the outer of said portions is slidable through the open end of the recess for size adjustment of the ring.

2. In a ring as in claim I wherein the inner end portion is reduced in thickness and wider than the outer end portion to close said recess in a manner to provide a smooth surface along the interior of the setting.

3. In a ring as in claim I wherein the inner end portion is reduced in thickness and wider than the outer end portion and said setting recess includes a second recess which extends from the floor of the first said recess radially outwardly and of the depth of the thickness of said outer end portion and the first said recess receives said inner end portion to be flush with the inner surface of the setting.

Claims

1. A ring formed of two assembled pieces of metal, one said piece being integrally formed of one piece of material and comprising an ornamental setting having a radially inwardly opening channel recess in its inner surface with said recess opening out through one end of the setting in a direction circumferentially of said ring and partly closed in said direction at the other end of the setting, said second piece consisting of a shank member integrally formed of one piece of material, said shank member being of generally circular shape and having overlapping radially inner and outer end portions located in said recess with the inner of said portions closing the inwardly opening recess and the remaining portion of the said other end thereof and the outer of said portions extending through the opening out of the recess through said one end of the setting, means securing the inner of said portions in said recess while the outer of said portions is slidable through the open end of the recess for size adjustment of the ring.

2. In a ring as in claim 1 wherein the inner end portion is reduced in thickness and wider than the outer end portion to close said recess in a manner to provide a smooth surface along the interior of the setting.

3. In a ring as in claim 1 wherein the inner end portion is reduced in thickness and wider than the outer end portion and said setting recess includes a second recess which extends from the floor of the first said recess radially outwardly and of the depth of the thickness of said outer end portion and the first said recess receives said inner end portion to be flush with the inner surface of the setting.
