Wonderful Work We No Wrought -- He

[Special Millwaukee (Wia.) Letter.
Thickly covered with grimy dust
there recently reposed in the junkroom
of a Milwaukee machinist the remains
of the first successful typewriter ever
built. The machine which has revolutionized commercial correspondence
had lain thus amid ignoble surroundings,
quite forgotten, for over twenty
years, but, like John Brown's body, its
soul was marching on.
"I saved it because the Ivory in the
keys was worth something, and I
thought I could use it over again some
time," said the machinist to the
writer. "If you want to pay me for the
ivory you can have it." A bargain was
immediately struck at $1, and both
parties to the transaction were abundantly
pleased. Four times the size
of the machine on the market todday,
a drayman was hired to bring the relic
from the machinist's, and when a tape
found to be two feet across by two and
was somewhat dismantled.
When in working order there was a
printing carriage that moved across
the top and printing types that were
arranged as they now are in the standard
machines. The keyboard, as is
shown in an accompanying view, was
modeled after that of the piano, there
being a row of white and a row of black
keys, back of which was a third row of

Slowed down sequential movement of adjacent typebars.
If manuscript reading, then the typebasket restriction might be.
If speaking by only their own tangs at the time in ad-live, then it might not.
Tang or mouth might have the restriction of not to speak bad and not to chose like tongue twister but smooth tongue, though.
The age of people living not to collide typebars.
The era of tamed people avoiding collision of typebars with living to chose keyboard wording ways.
A hundred years of Westerners writing with typewriter of manual operation.
Their keyboard wordings were filtered to go out though the typebaskets not to collide.
Bukowski could write (faster? maybe or) quicker than typewriter could, and could write on electric and Mac on and on.
Until Bukowski's wild heart tamed calm.
And then, the typewriter kept running for a while.
And later, electric introduced.
Or later, his IIｓｉ brought him to the Mac or PC stage of poet..

Slow and calmed down operators after front-striking era.
As Stickney proposed in his patents of US676208 or US889344, the risk to collide typebars each other was increased in change from up-strike to front-strike.
But the direction and the stream to change from up- to front- did not change and continued.
Without Stickney's patents of these execution.
Why? Visible, yes. But besides..
So why they do not jam so badly in front-strike era?
Because typist became slow.
Slow against quick or harry haste or rapid.
Even if the typing speed is fast, if the interval of sequential keying is kept enough, typebars do not collide.
