Abstract
A silent chain comprising link plates each having a pair of meshing teeth adapted to mesh with a sprocket tooth, and a pair of connection pin insert holes through each of the link plates adjacent opposite ends thereof. A pair of long and short connection pins are inserted into each of the insert holes. The long connection pin has opposite ends secured within holes formed in guide plates disposed adjacent opposite sides of an array of link plates, which guide plates prevent disengagement from the sprocket teeth. The rigidity of the guide link with respect to transmission of tension along the chain is about one-half the rigidity of the meshing link plate.
