This chapter is intended to be used as an idea generator. Following the adage that a picture is worth 1000 words, this chapter was assembled with millions of words in figures and virtually none using the alphabet. I have taken the liberty of varying dimensions to better show the principle of operation. You should not scale the figures, but follow the regular synthesis procedure to determine the proper dimensions for the application in mind.
In this chapter a new notation is used for the kinematic representation of joints or pairs in a linkage.
[ ] Readers will note a difference in the style and character of the figures in this chapter. When this manuscript was received, the illustrations, all conceived and executed by Professor Torfason, were seen to be original and unique. We asked for and received from the publishers special permission to reproduce them exactly as they were drawn EDS.
