Patent

CA 2249159

A ring is able to make different sizes without cutting or stretching the shank of a ring. It is necessary to have moveable joints in the shank and secure enough not to move without very heavy pressure. Ends of shank are connected separately on four sliding tubes which slide in pairs, on two sliding bars. Two screws are used to hold the sliding bars secure on desired place and also able to change the shank of the ring to a desired size. This process is done by turning the two screws clockwise or anti-clockwise.
