Claims2
A link plate for a silent chain having a back, a pair of pinholes, each pin hole being adapted to receive a connecting pin, and a pair of teeth, each tooth having a tip, an inner flank, and an outer flank, wherein each said outer flank extends from a shoulder adjacent the back of the link plate toward the tip of said tooth, and wherein said outer flank comprises first and second parts connected to each other by a step, the first part being positioned farther than the second part from said back of the link plate, the first part protruding relative to the second part and comprising a first straight linear edge portion adapted to engage a sprocket tooth, and the second part comprising a second straight linear edge portion, the second part being in a retracted position relative to the first part so that the second straight linear edge portion is prevented from coming into contact with a sprocket tooth.
