FINGERRING.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application riled March 27, 1919. Serial No. 285,412.

To all whom it may concern:

Be it known that I, ABRAHAM SCHWARTZ- MAN, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Finger-Rings, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates generally to jewelry and, more particularly, to a certain new and useful improvement in finger-rings, my invention pertaining especially to fingerrings of the type including collets or gemsettings.

The principal object of my present invention is to provide a composite ring of the type stated comprising in its construction two units, a main unit consisting integrally of the shank proper of the ring and ap proximately one-half of the collet or gem setting, and a second or complementary unit consisting integrally of a shank-portion and the remaining approximately onehalf of the collet or gen'i-setting, the shank of the main unit being suitably formed to receive the shanlcportion of the second unit and the two units being welded, brazed, soldered, or otherwise permanently united in a manner to expose in the finished ring a minimum of seam, and to provide for the making of my new finger-ring a simple, etlicient, (-ECOHOKDP cal, and expeditious method.

With the above and other objects in view, my invention resides in the novel form, construction, arrangement, and combmation of the several parts of the ring, all as will hereinafter be described and afterward pointed out in the claims.

In the accompanying drawing,

Figure 1 shows a suitable section or piece of material from which, as one of the steps in making the ring, the main unit blank is struck;

Figs. 2 and 3 show 111 elevation and section, respectively, the main unit blank as struck from such section of material;

Figs. l and 5 show in elevation and section, respectively, the main unit blank as die or otherwise pressed to substantially finished form and shape, the collet or gem-setting wall thereof being as yet solid and undivided;

Fig. 6 is a fragmental elevatlon of the tinished main unit, showing its collet or gemsetting wall milled or otherwise divided into the usual gem-engaging prongs;

Fig. shows a suitable section or piece of material from which, as also one of the steps in making the ring, the second unit blank is struck;

Fig. 8 an elevation of the second unit blank as struck from such section or piece of iaterial;

Figs. 9 and 10 show in elevation and section, respectively, the second unit blank as die or otherwise pressed to substantially finished form and shape, the collet or gemsetting wall thereof being also as yet solid and undivided;

Fig. 11 is an elevation of the finished second unit, similarly showing its collet or gem-setting wall milled or otherwise divided into the usual gem-engaging prongs;

Figs. 12 and 13 are plan and elevational views, respectively, of the finished or complete ring, ready to receive a setting;

Fig. la is a sectional view of the finished or complete ring taken approximately on the line l41&', Fig. 13; and

Fig. 15 is a sectional view of the finished or complete ring taken approximately on the line 1515, Fig. 13.

Referring to the said drawing, in which like reference characters refer to like parts throughout the several views, my new ring consists of a main unit A and a second, complementary or cooperating unit B, the two units A and B being welded, brazed, soldered, or otherwise substantially integrally united in the finished, complete ring.

Included in the main unit A is the shank and approximately one-half of the collet or ge1n-setting of the ring; and in providing the main unit A, I first take a suitable sec tion 1 of sheet material, such as gold, and cut or strike therefrom a blank, such as shown in Figs. 2 and 3, such blank comprising a ring 2 and an offset 3 having, as it might conveniently be described, somewhat the shape in side elevation of a key-stone integ-al at its base with the ring 2. Such blank is then, by means of suitable dies or the like and hydraulic or other presses, pressed into the approximately finished unit form shown in Figs. l and 5, to provide and include the shank 4; of the ring and a collet or gem-setting section or wall 5, the shank 4 being, as so formed and shown, neatly rounded or converted on its outer face or circumference and of greater thickness at the base of the wall 5 than at a point diametrically opposite thereto, and the wall 5 being suitably longitudinally concaved or recessed, as seen in Fig. f, and obliquely outwardly or laterally presented relatively to the shank a, as seen in Fig. 5, and providing and constituting approximately one-half of the collet or gem-setting of the ring. As also as formed, the shank 4L is cut away or recessed, as at 6-6, upon one side and at the base of the collet-wall 5, to provide facets or faces 7-7 which stand approximately in the plane of the median line of the ring proper or shank 4c, and which facets are bounded at their outer ends, circumferentially of the ring, by shoulders 8, at their inner ends, also circumferentially of the ring, by the inner perimeter of the concaved or semi-conical wall 5, and at their upper ends by depressions or the like 9 formed in the side edges of the wall 5, as seen especially in Fig. 5. Also in the unit so formed and shaped, a dowel-pin 10 is provided approximately centrally of and upon each facet 7 to project over or across the said median line of the ring proper or shank l, for purposes hereinafter appearin The wall 5 of the unit is then suitably, by milling or otherwise and by substantially ll-shaped kerfs, divided throughout its major portion to provide suitable conveniently bendable gem-engaging prongs 11.

The second unit Bis formed in a manner substantially similar to the formation of main unit A, that is to say, I first take a suitable material-section, such as the section 12 of Fig. 7, cut or strike therefrom ablank, such as shown in Fig. 8, and then press such blank into the shape and form shown in Figs. 9 and 10 to provide or include an arcuated base or shank-portion 13 and a collet or gem-setting wall 1a projecting laterally from the base 13. The second unit B is adapted to cooperate with and complement the main unit A in the production of the finished or complete ring and for such purpose has a width circumferentially at its base or shank portion 13 to fit neatly and exactly between the shoulders 8 and upon the facets 7 or the shank 4 of unit A. For such purpose also and to neatly match the facets 7, the portion 13 of unit B is'formed upon one or its inner side with flat faces or facets 15 in exact duplication of the facets 7, except that, instead of the dowel-pins 10, each of the facets 15 is provided with a recess or seat 16 to accommodate and receive the dowel-pins 10 in the unification of the units A and B in the finished or complete ring, as seen in Fig. 14. The collet portion 1a of unit B is likewise, as shown in Fi 11, throughout its major portion, divided into a plurality of conveniently bendable gem-engaging prongs 17. Each unit A and iseaew B is, if necessary, finished by bufling or the like to remove any die-marks, fins, or other such imperfections.

The units A and B being so formed and finished and being of the relative size and shape shown and described, I then seat or position the unit B at its portion 13 upon the facets 7 and between the shoulders 8 of the main unit A, the dowel-pins 10 being received by and fitting in the recesses or sockets 16, and then by preferably soldering merely at the matching facets 7 and 15 of the units, unite the units substantially integrally together to form the complete or finished ring illustrated in Figs. 12 to 15, both inclusive.

The production of a finger-ring according to my invention is exceedingly simple and economical both from a material and time-standpoint, and by my invention I am enabled to produce the rings substantially in any quantity with uniformity, without waste of material, and at a saving of both time and labor. And a finished ring of my invention, although made and produced at and with a saving in time, labor, and material, presents the appearance and is substantially the equivalent of the standard individually molded rings of this type on the market today. In the finished ring of my invention formed of the units A and B, the unit B, as seen especially in Figs. 12 to 15, both inclusive evenly complements the unit A and forms substantially, both at its shank-portion 13 and collet-forming wall let, an integral continuation of the shank a and collet-forming wall 5 of the main unit A, the complete or finished ring being smooth, unbroken, and uninterrupted upon its outer surface and the only seams or joints visible upon the ring at any time being the short cross lines upon one side of the shank at the shoulders 8 and the short curvilinear lines of the meeting facets on the inner and outer faces of the shank immediately adjacent the collet or gem-setting of the ring, and even with respect to such exposed seams it will be evident that the same will be practically concealed from view when the ring is worn, since the mounting or stone of the ring will practically cover the outer seam lines and the inner seam lines will be completely covered by the finger.

By preference, in order to facilitate the fitting or mating of the units A and B, I employ the dowel-pins and the sockets therefor, as described, but I do not wish to be understood as limiting myself to their employment; and while I have shown and described a ring of my invention having a gem-setting of the prong type, it will be understood also that the setting may equally well be of the bezel or other types, and that other changes in the form, construction, ar-

rangeinent, and combination of the several parts of my new finger ring may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. As a new article of manufacture, a composite ring of the type described formed of a main unit and a second or complementing unit, the main unit consisting of the ring-shaped shank proper of the ring and a collet-section projecting laterally from the shank, the shank being recessed upon one side and at the base of the colletsection, the second unit consisting of an arcuated base and a duplicating collet-section projecting laterally from the base, the base of the second unit fitting in the recess of, and being permanently united to, and completing, the shank of the ring and the colletsections oi? the two units completing the entire collet of the ring.

2. As a new article of manufacture, a composite ring of the type described formed of amain unit and a second or complement ing unit, the main unit consisting of the ring-shaped shank proper of the ring and a longitudinally concaved divided wall projecting laterally from the shank and providing a half section of the collet, the shank having a shouldered recess upon one side and at the base of said collet-wall, the

second unit consisting of an arcuated base and a longitudinally concaved divided wall projecting laterally from the base and providing a duplicating half-section of the collet, the base of the second unit fitting in, and between the shoulders of, the recess of, and being permanently united to, and completing, the shank of the ring and the halfcollet-sections of the two units completing the entire collet of the ring.

3. As a new article of manufacture, a composite ring of the type described formed of two complementing blanked and pressed units, one unit consisting integrally of the solid ring-shaped shank proper of the ring and a longitudinally concaved divided wall projecting laterally from, and to one side of the median line of, the shank and providing a half-section of the collet, the shank having a shouldered recess at the base of said collet-wall, and the other unit'consisting integrally of an arcuated base and a longitudinally concaved divided wall projecting laterally from the base and providing a duplicating half-section of the collet, the base of the second unit fitting in, and between the shoulders of, the recess of, and being premanently united to, and complet ing the shank of the ring and the halfcollet-sections of the two units completing the entire collet of the ring.

In testimony whereof, I have name to this specification.

ABRAHAM SCHWARTZMAN.
