U.S. Patent #2486473, "TYPEWRITER RIBBON AND SPOOL" by H. J. Hart (1946)On my Royal's ribbon spools, there is a small hook that drops down: the ribbon holds it in place when it's wrapped around the core, but when you reach the end, the hook lowers and trips the reverse mechanism, and what was now the end of the ribbon becomes the beginning. (This is a snip from the patent drawing, above.)
We're ending week two of NaNoWriMo, and maybe you're feeling a little at-the-end too? Like you've typed all you can and have run out of ideas? Time to invoke the Hook: make a change, kill a character, summon those monkey ninjas from the ninth dimension. Do something dramatic and you'll have a whole fresh story all laid out before you.
All the way to 50K, people. You can do it.
