f'pletely of the stone.

The invention contemplatestlie drawing down into xed position of the stone against a resilient member so that when the securing means maybe drawn up snugly, the stone will in turn be drawn down to a nal position against that resilient means and be continued to be backed up thereby.

The primary advantage of the invention resides in the fact that breakage of the stone is reduced to a very low minimum, and moreover a tightness of the mounting of the stone is preserved over practically the life of the ring. Also, by use of the invention in the factory stones are readily mounted with a degree of speed, due to the fact that the stone is not mounted against a solid, non-resilient base as has heretofore been the case.

The invention may be applied to various stone mountings including the recessed mounting, or these mounting-s wherein there is a bezel entirely around the periphery of the stone, the bezel being rolled or peened over after the stone has been completely fixed in position.

Not only is the breakage of the stones reduced by use of the invention, but the Workman is able to mount the stone with perhaps less skill and with more certainty of securing a rigid, tight mounting.

These and many other objects and advantages of the invention will become apparent to those versed in the art from the following description, which is made in reference to the accompanying drawing, in which Fig. 1 is a view on an enlarged scale of a ring mounting in top plan;

Fig. 2 is a similar top plan View but with the stone and crest removed; Y

Fig. 3 is a view in section on the line 3-3 in Fig. l; and

Fig, 4 is a detail in section transversely of the mounting.

While the invention may be applied to a great range of styles of mountings, it is herein shown as applied to a recess mounting. The shank IB is prepared in the usual manner With a central fiat area I I. A base I2 is formed to have a central opening I3 therethrough herein shown as being rectangular. This base I2 is aflixed to the 1 claim. (elysa- 15) shank in the. usual and well known manner. Around the base opening I3, there is provided a ledge I4 entirely therearound. as the margin of the opening I3. There is placed within the ledge vI4 a spring member I6 in a generally H-shape to rest on the iiat area II. This member I6 has aV transverse width slightly less than the transverse Width ofv the opening I3, and is' provided with the pairs of legs Ii, i8, and I9, 2D on the opposite ends thereof. The overall length of the member I6 is less than that of theopening I3, and, moreover, this member I6 is arched in that it is concave from the underside and convex from the upper side as indicated in Figs. 3 and 4. The member it is made out of any suitable material which will be spring-like in nature, such as bronze or a beryllium copper composition.

Then a stone I5 is placed over the spring member i6 and a metal crest 2l having two downturned posts 22 and 23 is brought over the stone I5, and these posts 22 and 23 are inserted downwardly through the stone I5, the stone I5 being provided with apertures 30 and 3| therefor, so that the posts 22 and 23 will pass between the arms I1, I8 and I9, 20 respectively, as indicated in Fig. 3. These posts may be solid or tubular as herein shown.

These posts 22, 23 have suilicient length to extend through and below the under side 32 of the shank I B, so that the extending ends of these posts 22, 23 may be ared, spun, peened, or riveted over against the under side 32 se as to draw down the crest 2l against the stone I5 and in turn to press it against the spring I6 to` compress the spring It somewhat but still have the spring I6 yieldingly space the under side of the stone I5 above the ledge I4. The thickness vertically of the spring Itis made to be such that when it is drawn down to that compression just indicated, it will preserve sucient curvature to space the stone above the ledge.

The stone is preferably beveled on each end as at 33 and 34 so that the upturned base ends 35 and 35 may be worked over these ends 33 and 34 of the stone I5 to complete the mounting to prevent play endwise of the base. The stone I5 iits between the side walls 37 and 38 of the base.

Thus the stone I5 and its overlying crest 2l are very securely mounted on the shank IIB in a secure manner, and yet in a manner whereby the central area of the stone I5 is resiliently supported to be yieldingly held against possible fracture during the mounting operations as well as against breakage from accidental knocks when the ring is in use. In actual practice, the clear- Without departing from the spirit of the invern., tion, and I therefore do not desire mbe, limited,
