Meaning

typebar (plural typebars)

In some typewriters, an arm actuated by pressing the keys that carried the type to strike the ribbon to form a letter.

Examples

A "noiseless" typewriter has a complex lever mechanism that decelerates the typebar mechanically before pressing it against the ribbon and paper in an attempt to dampen the noise. Source: Internet

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

It used a traditional typebar mechanism, not the "golfball" IBM Selectric typewriter mechanism, which was not introduced until the next year. Source: Internet
