Gravity would then return the typebar to its initial position.

Either mechanism caused a different portion of the typebar to come in contact with the ribbon/platen.

Another describes a typewriter with a low-velocity typebar that eliminates noise.

Soule, for example, suggested a circular typebar orientation.

The Kleinschmidt 100-words-per-minute typebar page printer became the standard for US forces in 1949.

Which features the "qwerty" keyboard, the typebar, ribbon, cylinder and carriage return lever.

The Lettera 22 is an oblique frontstroke typebar typewriter.

When a key was pressed, the corresponding typebar would swing upwards, causing the print head to strike at the center of the ring.

Seeing this, Mary returns the "M" typebar to Max's typewriter and sits down next to him with her son.

The machine's analysers recognized each of the thousand-odd phonetic symbols; there was a typebar for each sound.

Max ends his communication with Mary, by breaking the "M" typebar from his typewriter and sending it to her.

Depressing a key caused a typebar to rise from underneath the paper, pressing the paper upwards against the ribbon and thus printing an inked character.

The result is that each typebar could type two different characters, cutting the number of keys and typebars in half (and simplifying the internal mechanisms considerably).

Unlike the later IBM Selectric typewriter, this typewriter model used a conventional moving carriage and typebar mechanism.

Where the keystroke had previously moved a typebar directly, now it engaged mechanical linkages that directed mechanical power from the motor into the typebar.

The Flexowriter printed with a conventional typebar mechanism while the Selectric used IBM's well-known "golf ball" printing mechanism.

When a key was struck briskly and firmly, the typebar hit a ribbon (usually made of inked fabric), making a printed mark on the paper wrapped around a cylindrical platen.

They used the conventional moving carriage and typebar mechanism, as opposed to the fixed carriage and type ball used in the IBM Selectric, introduced in 1961.

Crandall soon worked out an oscillating typebar which he obtained a patent for; this prints capital and lowercase characters by shifting the platen, and was later used in Remington typewriters.

So-called "noiseless" typewriters have a complex lever mechanism that decelerates the typebar mechanically and then presses it against the ribbon and paper in an attempt to render the process less noisy.

An early innovation in mechanical typewriters was the introduction of a second character on each typebar, thereby doubling the number of characters that could be typed, using the same number of keys.

As the user writes or types on the original, the pressure from the typebar or pen deposits the ink on the blank sheet, thus creating a "carbon copy" of the original document.

There were minor variations from one manufacturer to another, but most typewriters followed the concept that each key was attached to a typebar that had the corresponding letter molded, in reverse, into its striking head.

The second character was positioned above the first on the face of each typebar, and the shift key caused the entire type apparatus to move, physically shifting the positioning of the typebars relative to the ink ribbon.

There was no particular technological requirement for the QWERTY layout since at the time there were ways to make a typewriter without the "up-stroke" typebar mechanism that had required it to be devised.
