JEWELRY SETTING.

Application filed January 7, 1922. Serial No. 527,664.

To all 'za/1.0m t ymay concern.'

Be it known that l, 2nein GRnnNrInLn, a citizen o1" the Unit-ed titates, and a resident of the city oit New York, borough of Manhattan, in the county and State oi' New York, have invented a new and improved .lewelry Setting, ot which the following is a` lull, clear, and enact description.

This invention relates to a setting lior ewels, and has tor an object the provision of means whereby a jewel ina-y be fastened in place on the setting and released therefrom in a very simple manner.

Another object resides in the provision of means whereby the support tor the jewel is readily adjustable and yet is as secure and irm as the usual type ot setting.

A further object resides in the particular' construction and arrangement o'l' parts which are hereinafter described and claimed and shown in the accompanying drawings. i

The invention is illustrated in the drawings, oli' which- Figure 1 is a side elevation with the upper end of the ring shown in section.

Fig. 2 is a vertical transverse section taken on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 1.

Fig. 4l is a horizontal section taken on the line 1 -l of Fig. 1.

rlhe -form oli' the invention shown .in the drawings is a preferred it'orm, although it is understood that modifications -in the construction and arrangement of the parts and in the character of the materials used maybe adopted without departing Jfrom the spirit oit' the invention.

The form of the invention shown in the drawings comprises a ring having a body portion l the upper surface oil' which is formed with a groove 2 to receive the lower end 3 of a rotatable sleeve 4t. As shown in Fig. 2, the upper end of the ring instead of being formed with a groove 2 may be provided with a flat flange portion 5 on which the lower edge of the sleeve fl rests. This sleeve is at its upper end provided with ears such as 3 which are crimped over the edges of a flat, preferably circular, plate 7. This plate 7 is provided with a plurality of radially extending grooves or slots 8 in its edge. These grooves or slots 8 are adapted to receive portions of prongs 9. These prongs, o'l which there may be several, are at their ylower ends pivoted as at 10 to a flange pory be threaded in a bore 13 formed in the upper surface of the body portion l of the ring.

The upper ends le oic the prongs are formed.v

in any suitable manner to engage the sur iace'oi the ewel 15. It will be observed that as the sleeve el is rotating in one direction the plug 12 will be screwed into the bore 13 and this will tend to draw the prongs down Jinto the sleeve et and tighten them.l on the jewel. A reverse operation will cause the prongs to extend further out of the sleeve through the slots 8 and will tend to release the jewel. As shown in Fig. 2 l may provide a pin 16 which can extend through the side of the sleeve and into a suitable bore of the body portion to lock the sleeve in a desired position.

As shown in Figs. 2 and d particularly, the specilic manner of fastening the prongs to the flange plate l1 is by turning over several earportions such as 17 formed on this plate and running an element, such as a wire 18, through these turned-over ear portions. the lower ends ot the prongs being strung on this wire as shown by the numeral 19 in Fig. Ll.

The main idea, however', resides in the t'act that the jewel is gripped by a plurality of prongs and that means tare provided whereby the prongs can be at will released from the jewel. 'l he particular specific means whereby this general idea is achieved may form a plurality of diderent devices or constructions.

l/Vhat I claim is:

l. A jewel setting which comprises a body portion having a threaded aperture therein, a threaded plug to be disposed in said aperture, a plurality of jewel engaging prongs pivoted to said plug, a sleeve mounted for rotation on the body portion, a plate closing the upper end of the sleeve and having slots therein through which the prongs entend to grip the jewel, said sleeve by being rotated tending to screw the plug into and out of the body portion whereby the prongs will grip or release the jewel.

2.' A jewel setting which comprises a body portion having a threaded aperture therein, a threadedplug to be disposed in said aperture, a plurality of jewel engaging prongs pivoted to said plug, a sleeve mounted for rotation on the body portion, a plate closing the upper end of the sleeve and having slots therein through which the prongs extend to grip the jewel, said sleeve by being rotated tending to screw the plug into and outrof the body portion whereby the prongs will grip or release the jewel, and means engaging the body portion and the sleeve to lock the two together.

3. A jewel setting which comprises a. body portion having a threaded aperture theref in, a threaded plug to be disposed in said portion having a threaded bore therein, a threaded plug to extend into said bore, a plurality of spaced, turned-over ear portions on the upper edge of said plug, a wire extending through said turned-over portions, and a plurality of jewel-engaging prongs ino'unted on said wire.

5. A jewel setting which comprises a body portion having a threaded bore therein, a threaded plug to extend into said bore, a plurality ol spaced, turned-over ear portions on the upper edge of said plug, a wire extending'through said turned-over portions, a plurality ot jewel-engaging prongs n10unted on said wire, and a cup-shaped sleeve mounted on thc body portion with its open end resting thereon and having slots in its closed end through which the prongs extend `to engage a. jewel, said sleeve by being rotated in one direction or another causing the threading oil the plug into or out of the bore whereby the prongs will engage or release the jewel.
