Abstract
Abstract A typewriter ribbon re-inker is disclosed which is capable of being readily attachable to a standard typewriter ribbon spool and has the capability of applying different color inks to the ribbon without blurring or intermingling. The sub-base, which is attached to the spool, defines two separate and independent ink vessels in which is placed an ink abosrbing material. The ink absorbing material passes through an extension channel communicating with each ink vessel and contacts a roller to supply ink to the roller. The roller, in turn, contacts the typewriter ribbon to transfer the ink to the ribbon.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
170 words
A typewriter ribbon re-inker for re-inking a ribbon on a typewriter having at least one ribbon spool wherein said spool has at least one exposed planar surface, said re-inker comprising: a. a sub-base portion defining two separate and independent ink vessels therein; b. means defining two extension channels formed with said sub-base portion such that one extension channel communicates with each ink vessel defined by the sub-base; c. ink absorbing means disposed in each of said ink vessels and said extension channels; d. at least one roller rotatably attached to a distal end of said extension channel defining means such that it contacts said ink absorbing means and the typewriter ribbon so as to transfer ink from said ink absorbing means to said typewriter ribbon; e. means to attach said sub-base portion to the exposed planar surface of said typewriter ribbon spool such that said spool may rotate relative to said re-inker; and f. means engaging the typewriter ribbon to prevent rotation of the re-inker as said ribbon spool rotates.
Claim 2
Dependent Claim
170 words
A typewriter ribbon re-inker for re-inking a ribbon on a typewriter having at least one ribbon spool wherein said spool has at least one exposed planar surface, said re-inker comprising: a. a sub-base portion defining two separate and independent ink vessels therein; b. means defining two extension channels formed with said sub-base portion such that one extension channel communicates with each ink vessel defined by the sub-base; c. ink absorbing means disposed in each of said ink vessels and said extension channels; d. at least one roller rotatably attached to a distal end of said extension channel defining means such that it contacts said ink absorbing means and the typewriter ribbon so as to transfer ink from said ink absorbing means to said typewriter ribbon; e. means to attach said sub-base portion to the exposed planar surface of said typewriter ribbon spool such that said spool may rotate relative to said re-inker; and f. means engaging the typewriter ribbon to prevent rotation of the re-inker as said ribbon spool rotates.
Claim 3
Dependent Claim
