Title: Sound deadened chain

Abstract: The chain is formed of a series of links of general C-shape with the link diameter greater than the width of the gap at the ends of each to prevent disengagement therethrough, and a sound absorbing continuous length of sash cord of a diameter substantially equal to the gap width is combined with the chain length by insertion through the link gaps of such cord successively in alternating fashion along the length of the chain.
