1 Claim.

This invention relates to improvements in interchangeable settings for finger rings, brooches, and other articles of jewelry, and the objects of the invention are as follows:

First, to provide a finger ring which shall comprise a ring band having a setting secured thereto, whereby bands of different size or of different ornamental character can be easily and quickly combined with settings of different ornamental character to facilitate and make possible to interchange a certain setting with various bands so that the quantity of settings which a jeweler has to keep in stock can be decreased, thereby having a larger number of bands so as to be able to fit fingers of different sizes more easily.

Second, to afford facilities for the proper securing of the setting to the ring band, brooch or the like so that the setting cannot be lost while the article of jewelry is worn.

Further objects of the present invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawing whether within or without the scope of the appended claim and irrespective of other specific statements as to the scope of the invention contained herein.

In the drawing:

Figure 1 is an enlarged side elevation of a ring constructed according to the invention, showing the ring band and the setting partially in crosssection on the line II of Fig. 3; Fig. 2 is a vertical section of the ring band and setting on the line 22 of Fig. 1; Fig. 3 is a top plan view of the ring band as it appears after the removal of the setting; Fig. 4 is a bottom plan view of the setting as it appears after the removal of the band; Fig. 5 is a cross-section of a ring constructed according to a modification of the present invention; and Fig. 6 is a side elevation of the modification shown in Fig. 5.

Similar numerals refer to similar parts throughout the several views.

The purpose of the present invention, as previously stated, is to connect a setting to a band in such a manner that it can easily be interchanged. This can be done in various ways, as for instance by a simple snap connection, by a screw connection, and the like. I prefer, however, to carry out this feature of my invention in the manners shown in the drawing and hereinafter described.

Referring first to Figs. 1 to 4 inclusive, the ring band I has a head 2 with a flat surface 3, in the center of which is an internally threaded aperture 4; and the setting 5, which may hold a stone 6 or any other ornament, has at its bottom 1 a threaded pin 8 and notches 9 arranged circumferentially around the pin 8. The head 2 of the band I is provided with a groove It, in which a resilient arm I I, carrying a latch I2, is provided and secured to the head 2 by a screw I4. The part I5 of the groove I0 is downwardly inclined to allow a vertical movement of the arm II, as may be seen in Fig. 1.

To attach a setting to the band, one screws the bolt 8, which is secured to the setting by riveting or in any other suitable manner, into the aperture 4 of the band until the setting is tightly .screwed to the band. Thereby the latch I2 engages one of the notches 9, and since the side I6 of the latch I2 projects perpendicularly from the arm II, it secures the screw connection between setting and band so that the setting cannot become loose and cannot unscrew itself from the band.

To detach the setting from a band, one presses the arm II downwardlyas deep as possible into the part I5 of the groove I0, whereby the latch I2 disengages the notches 9, and then the setting can be unscrewed from the band.

According to the modification of the invention shown in Figs. 5 and 6, the ring band I is also provided with a head 2, having a flat surface 3, with an inwardly threaded aperture 4 in its center, and a threaded pin 8 is secured to the bottom of the setting 5. In this case, however, the bottom of the setting 5 is not provided with notches, and instead of a resilient arm and a latch, a set screw I8 and a lock nut I9 are used.

The set screw I8 can be screwed into a threaded hole at one side of the head 2 so that it presses radially upon the pin 8, thus preventing the pin 8 from unscrewing. As a second securing means, a lock nut I9 may be screwed on the lower part of the pin 8, and the lower part of the aperture 4 is countersunk or provided with a recess which allows the tightening of the lock nut I9 by means of a short elbowed box spanner not shown.

The ring band and the setting can also be made without lock nut I9, without set screw I8, and without a resilient arm carrying a latch I2, so that the setting is simply secured to the band by screwing the bolt 8 into the band.

Further modifications will be apparent to those skilled in the art and it is desired, therefore, that my invention be limited only by the prior art as determined by the scope of the appended claim.

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

In a finger ring, the combination of a ring band having a fiat head with an internally threaded aperture in its center, with a setting having a fiat bottom to which a threaded pin is secured and which has notches around said pin, and a latch carried by a resilient arm which is secured to said ring band, said latch being adapt- 5 ed to engage said notches at the bottom of the setting, substantially as described.
