Mechanical Toys - Perky Porky

The mechanical toy I have decided to make is Perky Porky. The mechanisms involved cause it to clap its hands while turning its head from side to side. It uses triangular cams connected to the pig's legs by bell crank linkages to create the clapping motion, which turns rotary motion into oscillating motion, and two circular cams for turning the pig's head, which also turn rotary motion into oscillating motion.
