Path dependency?
Scince around autum 2010, I've started trying to have contacts with some antique typewriter owners of having up-strike mechanism.

●SHOLES AND GLIDDEN TYPEWRITER 1874

I remember if that would be the very first time? to try to have a contact with Kikutake college, at Nagoya in Japan.. but, that was not for sure if it jams or not.That was for inquiry of key layouts and type-basket arrangements of typebars.

He APKY*1 have reported typebar arrangement of two S&Gs in

1. Milwaukee Musium or so and in
2. Kikutake college, Nagoya, Japan.

Those are not prototype but (after) (mass-?)production models, though.

Two of museums have the same arrangement of typebasket machine, which was reported by APKY. And this is what I'm guessing how is wired and connected to keys and keylevers from each typebars.

I've sent a mail to whom he looks to have up-strike machine, and he read Japanese, but his is look like Yost or so thinking later on.., might have grasshopper mechanism, then it should be litte bit different from ordinary up-strikes.. He said he cannot say much about jamming or not on S&Gs or so..
YOST NO.4 Typewriter

Then I sent mail to Darryl Rehr, who is famous in antique typewriter collectors.
Kindly enough, he sent response mails in several times.

Mr. Darryl Rehr answered to my questions. - The actuality on - QWERTY history:

にも書きましたが、

Sholes & Glidden(S&G)タイプライターは絡むという証言を、3人から得ています。

これで、プロトタイプ期直後の製品機にjamはあったとしてもよさそうです。
