Five quick questions, no timer and no sign-up. Start with what you recognize; each answer opens a little more of the story.

1. In Ladd’s 1908 eggbeater design, what drives both small pinions?
2. In Pajeau’s Tinkertoy design, what must be included when working out the connection length?
3. What lets the ends of Pajeau’s rods compress as they enter a socket?
4. In Bookman’s 1964 answer-toy patent, what brings the die toward an upward-facing window?
5. What stands above the die’s flat face in that patent?
