ABSTRACT:
Mechanisms are disclosed for modifying conventional single element and typebar typewriters, having character-for-character correction systems, with automatic backspacing or non-backspacing, and non-forward spacing, after obliteration, to provide an additional operational mode whereby character-for-character correction can be achieved with automatic forward spacing, after each obliteration, thereby to provide simplified word obliteration.
