Title: Flexible correction auxiliaries for use with golf-ball typewriters

Abstract: Several typewriter auxiliaries for use with typewriters of the single-element ("golf-ball") type, to facilitate the making of corrections, either by the use of camouflage (cover-up) tapes or ribbons, or lift-off tapes. Varying degrees of automaticity are achieved in performing the correct operational sequences. In general, these auxiliaries are carried by, or supported from, the main carrier of the typewriter, which provides the travel motion of the single-element printing device in the linewise direction across the impression sheet. These auxiliaries are so designed that they are readily attachable (and removable) by the ultimate user, without the need for special tools or specialized personnel, and without any structural alteration of the typewriter.
