A self-adjusting finger ring size reducing mechanism has spring biased arms pivotally mounted in a slot in the lower shank portion of a ring. The arms are urged into the finger opening by the springs comprised in the slot by the arms and are retained in the slot by a bridge across the top of the slot intermediate its ends which engages the free ends of the arms to limit their movement out of the slot. The mechanism can be retrofitted to existing finger rings.

The finger ring size reducing mechanism of claim 6 wherein the arms each have an opening therein adapted to be positioned opposite the slot base for retaining one leg of a spring.10. The finger ring size reducing mechanism of claim 6 wherein the biasing device is a single spring having opposed free legs engaging the undersides of the arms, said spring being adapted to be compressed between the base of the slot and the arms and normally urging the arms into the finger opening.11. The finger ring size reducing mechanism of claim 6 wherein the arms are adapted to be attached to the shank by a pivot pin having ends adapted to be fixed in recesses in the outside walls of the shank and the recesses are adapted to be filled with the same material as the ring shank and polished to effectively mask said pin ends a nd the recesses.12. A finger ring comprising: a) a setting, b) a shank having an inner wall, an exterior surface and a lower portion opposite the setting, the shank defining a finger opening having an inwardly opening slot recessed in the inner wall thereof opposite the setting, said slot having a base facing the finger opening, wherein the slot has opposed ends and an open top, c) a finger opening size reducing member positioned in the slot and retained therein, and having a pair of arms pivoted adjacent the ends of the slot with each arm having a free end, d) biasing spring means having legs positioned between the size reducing member and ring shank slot and arcuate portions connecting the legs, the arcuate portions positioned at least partially in the size reducing members, the spring means biasing the size reducing member outwardly from the slot into the finger opening opposite the setting to reduce the size of the finger opening, e) the size reducing member being movable into the slot to define the maximum finger opening size of said shank. 13. The finger ring of claim 12 wherein the biasing means comprises coil springs positioned at the free ends of the arms between the arms and the base of the slot.14. The finger ring of claim 13 including a bridge across the slot in the shank intermediate the ends of the slot adapted to engage the free ends of the arms to limit movement of the arms into the finger opening while allowing movement of the arms into the slot.15. The finger ring of claim 12 wherein the size reducing member is a pair of arms each pivotably connected at one of their ends to the shank with the other end free and the biasing means is a single leaf spring having coils at its ends beneath the free ends of the arms.16. The finger ring of claim 12 wherein the size reducing member is a single arm pivoted at one end to the slot and a leaf spring is positioned beneath the arm between the arm and the slot.17. The finger ring of claim 12 wherein the size reducing member is trapped in the slot and urged into the finger opening by a leaf spring positioned between the size reducing member and the base of the slot.18. A finger ring comprising a setting, a shank having an inner wall, an exterior surface and a lower portion opposite the setting and defining a finger opening having an inwardly opening slot recessed in the inner wall thereof, said slot extending around the lower portion of said shank opposite the setting and terminating on each side of said setting, an arm member including a pair of arms pivotally connected at one of their ends to the shank and positioned in said slot, the other of their ends being fee and unattached, the slot having a bottom wall and the arms having undersides opposed to said slot bottom wall, a single spring having opposed free legs engaging the undersides of the arms, said spring being compressed between the bottom wall of the slot and the arms and normally urging the arms into the finger opening, to reduce the size of the finger opening, the arm member being movable into the slot to define the maximum size of the finger opening of said shank. 19. The finger ring of claim 18 wherein the arms each have an opening therein opposite the slot bottom wall for retaining the fee legs of the spring.20. A finger ring size reducing mechanism adapted to be attached to a finger ring which defines a finger opening and has a setting and a shank with a lower portion opposed to the setting, the shank defining a slot in the lower portion which slot has a base which is open to the finger opening, the size reducing mechanism comprising a pair of arms, each having an underside and adapted to be pivotally connected at one of their ends to the shank and having the other end free and adapted to be positioned in the shank slot, a single spring having opposed free legs engaging the undersides of the arms, said spring being adapted to be compressed between the base of the slot and the arms and normally urging the arms into the finger opening to reduce the size of the finger opening, the arms adapted to be moved into the slot opposite the setting to define the maximum size of the finger opening. 21.
