ABSTRACT:
An attachment for a ordinary electric typewriter to convert it into a self-correcting typewriter. The attachment includes a frame which, when bolted to the frame of the typewriter, extends across the typewriter from one side to the other along a path just rearward of the keyboard and at a level higher than the keylevers.
The frame of the attachment carries two special keys and also carries a rod for operating the backspace keylever when either of said special keys is depressed and a second rod that selects a correcting field of a ribbon, when one of the special keys is depressed, and selects a writing field of a ribbon, when the other of the special keys is depressed.
