Patents of American Writing Machine says:

• In the drawings, A represents a type-writer key-lever, generally made of a strip Of wood,
• the finger-key stem d.  may be metal.
• The finger-key D is made of a bottom metallic disk,

It might be caused by carriage jump but in different.

And the far-left "A" just looks like the carriage jumped the margin when it was returned.

It might be caused by carriage jump but in a different way we now see.

The days when Sholes penciled "Is this paper thick enough?" and just ahead when he had typed out this letter to Densmore on October maybe18th, 1869,,



In those days, it seems they didn't have side moving roller carriage in longitude along the line out-printing mechanism.(Later they had as on Scientific American August 10th 1872.)





The mechanism they had a patent as cylindrical platen earlier was for moving in circumferential direction along the circular out-printing on the rotating cylindrical platen,
not for longitudal direction line printing.



If using their early cylindrical platen mechanism, then the incidents like carriage jump would rare happen.

And to roll up the cardboard might be hard to bend to set on the platen.

Sholes typed a letter to Densmore. Oct. 28 is not be accurate, and might be 18, 1869, on cardboard an eighth of an inch thick, and added a penciled note in which he triumphantly asked, " Is this paper thick enough?

So I guess the carriage jump might happen on an old model machine which made over adding with mechanism changed to like ink-ribbon winding in downward, or so.


But I should know more detail how paper had attached round on the cylindorical platen on these days of Sholes.

If 1/8-inch! Is the paper too thick enough to roll along platen?

The letter which Sholes penciled "Is this paper thick enough?" hears a cardboard of an eighth of an inch thick.

APKY(Associate Professor Koichi Yasuoka) might think in a book(cf. Koichi Yasuoka and Motoko Yasuoka: Myth of QWERTY Keyboard, NTT Publishing, Tokyo (2008)):

• the letter on Oct. 18th 1870 was typed on a similar model of machine of the patent No.118491 by Sholes,
  1. with the paper attached roll-up around on the platen, .
  2. (or the cardboard put as flat and weighed by the roller
     but this is funny cause the roller could run around only in one way..

I guess another alternative possibility:
Sholes might just only change the setting way of ink-ribbon rolled-downward, on old-type-machine, for testing..
and set the ink-ribbon under the surface of cardboard that Sholes typed at.

Some words seem left on a paper, of Clough or Jenne..

What words were left on the paper around platen? Do you read?

http://kygaku.g.hatena.ne.jp/raycy/20110519/1305742330

They've got digitized noise, and lost details of the original when google? degitezed.
If you could reach the analogue data of the drawings..
Are they some message that Clough or Jenne left? or so nothing?

Mr. Schwalbach's gift of some porcelains to Wisconsin Historical Society

it has several keys missing

I'm sure it should not be appropriate, but,,
If it were affordable for before S&G, some might be in Wisconsin Historical Society, once were of belongings of Mathias Schwalbach.

It hears that Schwalbach had done the four-bank keyboard and handed it to Sholes around the spring of 1871.

http://groups.yahoo.com/group/TYPEWRITERS/message/49446
I have a quick question about some terminology I've heard. I've heard some
machines referred to as 1, 2, 3, or 4 bank machines--what exactly does this
mean?

The saying of Schwalbach hears as follows:

http://content.wisconsinhistory.org/cdm4/document.php?CISOROOT=%2Fwmh&CISOPTR=17986&REC=0&CISOBOX=four-bank
p.398

his criticisms annoyed sholes but impelled him to go on making improvements the inventor soon adopted a new keyboard of Schwalbach's devising which consisted of four rows of metal key levers and buttons set in ascending banks.[18]

[18] Schwalbach afterwards said that " while he continued to work for Mr. Sholes for $3.00 a day during the winter of 1870 he took up the work independently in his home he worked out the four-bank key board and in the spring of 1871 he laid his completed model before messrs sholes and glidden howard in typewriter topics 3:8
