US Patent 8205471 Device for allowing addition and replacement of jewelry strands

A device for allowing jewelry strands to be added or replaced with two interlocking arms, two rotating members, two knobs, and a shaft. The closed end of each interlocking arm is attached to a rotating member, the shaft extends through an aperture in each rotating member, and a knob is situated on each end of the shaft. The two interlocking arms are roughly the same size. The interlocking arms are positioned one on top of the other such that they form a closed shape when the interlocking arms are in a closed position. The rotating members rotate about the shaft, thereby causing the interlocking arms to rotate relative to one another.
