Patent attributes
An ink cartridge has a pair of elongated, longitudinally extending, and transversely spaced side plates and a pair of short, transversely extending, and longitudinally spaced end plates bridging the side plates and forming therewith an downwardly open compartment adapted to hold a body of ink. Respective doctor blades extend transversely toward each other from lower edges of the side plates and define a floor of the compartment and a central downwardly open mouth adapted to feed ink from the body to a roll below the compartment. Respective axially spaced flexible bodies carried on the end plates are shiftable between outer positions generally disengaged from axial end edges of the doctor blades and inner positions bearing axially against the axial end edges.
