I have a 1878 Sholes model for US patent #207557 (August 1878) that was made to demonstrate an improvement in the typebars.
This specific model is a two-row keyboard machine with 12 keytops only

On a visit to the Smithsonian Institution recently, Ron Wild took this photograph of the first typewriter for which Christopher Latham Sholes received a patent. This is the "kickup" model, which James Densmore actually put into limited manufacture in Chicago during the summer of 1868.
The patent for this machine was granted on June 23, 1868, while the patent for Sholes' better known upstrike design was granted July 14, 1868. In actuality, the model of the second patent was developed first, as Richard Current points out in The Typewriter and the Men Who Made It.
Densmore and Sholes believed the kickup model was an improvement on the earlier machine, which used a linkage of wires to connect keys to typebars. The kickup model, with its piano-like keyboard, used simple metal fingers to push each typebar up, making use of the simple upward movement of the key levers.
The patent model shown here has only eleven keys, since it was built only to demonstrate the action of the machine. We can assume that the manufactured models had more keys, perhaps as many as the 44 on later machines. According to Current, Densmore expended $1000 and a lot of nervous sweat in having only 15 of these machines made in Chicago, where they were tested at the telegrapher's school operated by E. Payson Porter. Porter's students quickly pounded the machines into disrepair, providing the weakness of the design, which was then abandoned.
As far as we know, none of the 15 kickup models have survived.

In actual dimensions it is 2 feet long, 1-1/4feet wide, and exactly 1 foot high.
Nevertheless-and bear this fact in mind-every basic principle of the present-day typewriter is found in this machine.

The Zipf's curve on (English) language bi-grams (the letter pairs) in words might lead the team Sholes and Densmore to a success not to be abandoned.

The Zipf's curve that bi-grams have could lead to the less liable to interfere each adjacent typebar with on a type-basket.

I once wrote as:
I want to name your revision in "OWERTY Revisited(1997)" as "Rehr's revision".
Darryl Rehr's revision"The total frequency of adjacent typebar pair's bi- grams on a whole type-basket are aimed to be minimum or small.（1997）"
I slightly changed the mentioning of expression.
You, Darryl Rehr wrote as,like "(almost just) Only ADJACENT TYPEBARs are the matter", in 1997.
Rehr's revision:"Sholes needed to do was separate the letter pairs by at least one type bar.（1997）"
The total frequency of adjacent typebar pair's bi-grams on a whole type-basket are aimed to be minimum or small.(in2007or 2008or2009or so.)
I explained this in Japanese on:

I expressed recently as:
"The total frequency of adjacent typebar pair's bi-grams on a whole type-basket are aimed to be minimum or small.(in2007or 2008or2009or so.)"
This expression needs some assumption:
By this expression, I could count the total frequency of bi-grams of each whole typebaskets, historicaly.

Contrary to two common misconceptions - the QWERTY letter arrangement was not derived to slow down typists nor to avoid jamming.[1]
[1] Yasuoka, Koichi, The Truth of QWERTY
QWERTY - Wikipedia, the free encyclopedia
"nor to avoid jamming"?
Swing down or forward? No. Typewriters in the 1880s with QWERTY keyboard had typebars to swing up to hit the back of paper. They are called upstrike typewriters and their typebars never jam. Furthermore, in English, the most frequently-used letter sequence is "th". On QWERTY keyboard, you see T and H are adjacently placed. The second is "er" + "re", also placed in neighborhood of one another.
The Truth of QWERTY
He should point out at first, is "The design solution was to relocate the keys"
letters often typed immediately after one another, such as "i" and "e," would be placed on opposite sides of the machine.
It could be, as alphabet frequency
E is ▄ﾟ¯, T is ▄▄ﾟ¯, I is ▄ﾟ▄ﾟ¯, O is ▄ﾟ¯▄ﾟ¯
but how come sequence on type-basket wasn't discussed about?
If the typist worked too quickly, the metal typebars would collide and jam the mechanism.

Why do we all use Qwerty keyboards?
By Nick Baker Producer, BBC Radio 4
'Creative obstruction'
But did Sholes really doctor the configuration of letters to slow the typist? Would an inventor really hobble his own brainchild?
If so, argues Fry, then the Qwerty keyboard and its inventor could be accused of "conspiracy to pervert the course of language and to limit the speed of creativity and language input, endangering billions with repetitive strain injury".
Qwerty can be seen, he argues, as "a deliberate spanner in the works of language, metaphorically and technologically".
Qwerty is "not ergonomic", agrees Professor Koichi Yasuoka of Kyoto University, a world expert on the development of the keyboard.
But he sees evidence of the practicality of Qwerty in a world of mechanical typewriters. "T and H is the most frequently used letter pair in English," he explains. "In fact in Sholes's typewriter, the typebar of T and H are located on opposite sides."
The separation of these letters was made in the interests of speed, he believes. Users could type T-H without crashing keys, whereas the proximity of E and R, he argues, is inefficient. In other words there is no evidence of deliberate slowing down.
"Ergonomics were not a characteristic of mid-19th Century design," he concludes.

| mail1Q | Q2 | raycy | How are they, adjacent type bars? Are they apt to clash and jam? | |
| mail1A | A2 | Rehr | "Adjacent type bars" means two type bars that are next to each other inside the machine. They DO clash and jam. | |
| mail1Q | Q3 | raycy | AssociateKoichi Yasuoka, The Truth of QWERTYHow do you think? | |
| mail1A | A3 | Rehr | Professor Yasuoka is wrong. | |
| mail2Q | 2010年 11月 12日 01:02:39 +0900 | Q4 | raycy | You might say Professor Yasuoka's experience or opinion:"The up-strike machine's typebars never jam." is wrong. And You might say up-strike typewriters also apt to got jam in adjacent typebars move in rapid sequence? Are they right? Are those on your experience? |
| mail2A | Thu, 11 Nov 2010 08:19:15 -0800 | A4 | Rehr | On later models of upstrike typewriters, type bars jam less often than on the Sholes and Glidden. But on the Sholes and Glidden, they jammed frequently. |

Darryl Rehr"It appears that all Sholes needed to do was separate the letter pairs by at least one type bar. As long as they were not adjacent, they didn't clash.
So, it appears all we need to do is revise our theory slightly, and it need no longer be disscarded." QWERTY REVISITED on ETCetra No.38 / March, 1997/3
I want to name "Rehr's revision", that is "Sholes needed to do was separate the letter pairs by at least one type bar."
I said:
The total frequency of adjacent typebar pair's bi-grams on a whole type-basket are aimed to be minimum or small.(in2007or 2008or2009or so.)
I explained this in Japanese on:
