            14.17 CAM TO CONVERT LINEAR
            TO ROTARY MOTION

            Let us now analyze a novel inverse indexing cam design utilizing a continuous trilevel
            cam track. In this design (Fig. 14.20) a stationary cam pin rides in the cam track to convert
            horizontal  linear  motion  into  rotary  motion.  The  trilevel  track  guarantees  the  proper
