Abstract
Abstract A method and device for applying ink to a ribbon, such as a typewriter ribbon or the like. The device is characterized by a pair of ink-absorbent pads resiliently supported in a mutually opposed relationship for transferring ink to a ribbon as the ribbon is drawn between the pads in face-to-face engagement therewith.

A device for applying liquid ink to a ribbon for a typewriter comprising: A. a case of a substantially planar configuration including a pair of opposed case halves, each case half being characterized by an endless lip projected from the periphery thereof for defining in said case a pair of pad cavities; B. a pair of ink absorbent pads each being seated in a pad cavity and characterized by a face of a substantially planar configuration; C. hinge means interconnecting said case halves for pivotal displacement about a common axis including a linear hinge member extended in spaced relation with adjacent edge portions of said case halves; D. means for continuously urging the case halves in pivotal displacement for positioning the face of each pad of said pair of pads in an opposed relationship with the face of the other pad of the pair; and E. stop means for limiting pivotal displacement of said case halves about said axis including stop means comprising a linear protuberance projected from one edge surface of the face of each pad of said pair of pads and extended in spaced parallelism with said axis for engaging the protuberance projected from the face of the other pad of the pair as the case halves are pivotally displaced.
