Thought: Is there a reason they would intentionally/mistakenly show old layout on the patent?
Might be cheaper/easier to reuse old drawings than to make new ones? Another manual-style keyboard shown in https://patentimages.storage.googleapis.com/f2/5a/91/45eede4d2abff7/US1873554.pdf …, perhaps the same drawing as before
Here comes one about uniform impression, but it's about making keypresses that also drive a bookkeeping tally mechanism still have the same impression on the page as ordinary keys https://patentimages.storage.googleapis.com/20/c6/bb/f8ba6ace2dcdde/US2089310.pdf …
This one still seems to be sensitive only to Shift: https://patentimages.storage.googleapis.com/03/e2/01/e35e8479813231/US1945097.pdf …. Another one about heavier load from bookkeeping mechanisms: https://patentimages.storage.googleapis.com/00/8d/7a/161aa05ab9c701/US1934338.pdf …
A little off-topic, but an interesting one about a mechanism for typing in boldface: https://patentimages.storage.googleapis.com/89/b4/6c/c2742873e6c464/US1987276.pdf …
Also off-topic, but there's a bitmap font encoded in the drawings for this one: https://patentimages.storage.googleapis.com/33/ab/bb/bec1c58efb41fc/US2043707.pdf …pic.twitter.com/WrMmlJocgu
This one is about a tabulator mechanism, but it shows an electric key layout. https://patentimages.storage.googleapis.com/5b/0d/7c/eab953d596cd86/US2157053.pdf …pic.twitter.com/HKIiagaj1Y
Thanks! Either way it seems / and ? shared the key before electrics came around?
Yeah, that seems to be the one solid conclusion that can be drawn from this morning's patent digging
Maybe I just need to build a searchable library of typewriter keyboard layouts 1900–1930, as precisely dated as possible.
Sorry, I mean WE. :·D
