Abstract
Improvements in typewriters, with incorporation of keys for double and simultaneous pulsation, characterized by the fact that a typewriter has been provided, which is equipped with a keyboard to which keys corresponding to frequently used letters have been added, to allow the simultaneous treading of the new and conventional keys, reducing writing time.
