In combination, an inking device comprising a spool-like body, said body having a hub, a lower flange extending radially outwardly from said hub, inking pad retention means on said hub, said retention means being above said lower flange, a cellular polymeric inking pad on said hub above said lower flange and retained by said retention means, a cellular polymeric ink conducting pad beneath said lower flange and having a portion thereof projecting outwardly from beneath said lower flange and exposed to contact a lower portion of said inking pad only radially outwardly of said lower flange near the ink delivery surface of said inking pad, said lower flange overlying said ink conducting pad to be positioned between said inking pad and said ink conducting pad inwardly of said projecting portion, an ink reservoir in said hub, said hub and said lower flange isolating said inking pad from said ink reservoir whereby ink from said reservoir may be conducted to said inkink pad only at said exposed portion of said ink conducting pad, said ink conducting pad communicating in ink receiving relation with the ink reservoir to receive ink from said reservoir and conduct it to the portion thereof contacting said inking pad, means mounting said inking device for rotation on its axis, said inking pad having an exposed ink delivery surface above said lower portion, a business machine ink receiving means, means to advance said ink receiving means past said inking pad and to press it thereagainst at said ink delivery surface to pick up ink 6. A combination in accordance with claim 5 in which the ink receiving means is a ribbon and in which said inking pad is a tube which surrounds said hub between said lower flange and said retention means. 7. A combination in accordance with claim 6 in which the ink conducting pad is cocked-up near its outer periphery to contact said inking pad in a narrow band of contact only near the radially outer periphery of the inking pad. 8. A combination in accordance with claim 5 in which said ink receiving means is a type slug and in which said inking pad is a tube which surrounds said hub between said lower flange and said retention means. 9. A combination in accordance with claim 8 in which the ink conducting pad is cocked-up near its outer periphery to contact said inking pad in a narrow band of contact only near the radially outer periphery of the inking pad. 10. The combination which comprises an inking device including a spool-like body, said body having a hub, a lower flange extending radially outwardly from said hub, said hub being above said lower flange, an inking means on said hub above said lower flange, ink conducting means beneath said lower flange and having a portion thereof projecting outwardly from beneath said lower flange and in ink delivery contact with a lower portion of said inking means only radially outwardly of said lower flange near the ink delivery surface of said inking means, an ink reservoir in said hub, said ink conducting means communicating in ink receiving relation with the ink reservoir to receive ink from said reservoir and conduct it to the portion thereof in ink delivery contact with said inking means, said hub and said lower flange isolating said inking means from said ink reservoir whereby ink from said reservoir may be conducted to said inking means only at said exposed portion of said ink conducting means, said inking means having an exposed ink delivery means above said lower portion, said ink delivery means being adapted to be contacted by an ink receiving means and to deliver ink thereto. 11. A combination in accordance with claim 10 in which said inking means is a tube of cellular material which surrounds said hub above said lower flange. 12. A combination in accordance with claim 11 in which the ink conducting means is a pad of cellular material and in which said ink conducting pad is cocked-up near its outer periphery to contact said inking tube only near the radially outer periphery of the inking tube. 13. The combination which comprises an inking device including a spool-like body, said body having a hub, a lower flange extending radially outwardly from said hub, inking pad retention means on said hub, said hub being above said lower flange, a cellular polymeric inking pad on said hub above said lower flange and retained by said retention means, a cellular polymeric ink conducting pad beneath said lower flange and having a portion thereof projecting outwardly from beneath said lower flange and exposed to contact a lower portion of said inking pad only radially outwardly of said lower flange near the ink delivery surface of said inking pad, said lower flange overlying said ink conducting pad to be positioned between said inking pad and said ink conducting pad inwardly of said projecting portion, and ink reservoir in said hub, said ink conducting pad communicating in ink receiving relation with the ink reservoir to receive ink from said reservoir and conduct it to the portion thereof contacting said inking pad, said pad and said lower flange isolating said inking pad from said ink reservoir whereby ink from said reservoir may be conducted to said inking pad only at said exposed portion of said ink conducting pad, said inking pad having an exposed ink delivery surface above said lower portion, said inking pad being adapted to be contacted at said ink delivery surface by an ink receiving means and to deliver ink therefrom, a separable cap member adjacent said lower flange, a first depending rib on a wall defining said reservoir, said depending rib projecting toward said cap member, a cooperating upstanding rib on said cap member adjacent said depending rib and sealing thereagainst to close said reservoir against ink leakage past said ribs, said depending rib and said upstanding rib each having at least one opening therethrough, the openings through said ribs being positioned to be aligned to form an ink escape passage from said reservoir through said ribs, said upstanding rib being movable relative to said depending rib from a closed position in which the opening in one rib is closed by a facing portion of the other rib to close the reservoir to an open position to which the openings are so aligned, means mounting said inking device for rotation on its axis, a business machine ink receiving means and means to advance said ink receiving means past said inking pad and to press it thereagainst to pick up ink therefrom. 14.

A method of replenishing ink to a printing device which comprising storing ink in a spool-like body in an ink reservoir located generally inwardly of the body hub, transmitting ink from the reservoir to an ink receiving portion of an ink conducting cellular pad, conducting ink through the ink conducting pad to a portion thereof lying exposed to the lower portion of a cellular inking pad mounted on said body, contacting the exposed portion of the ink conducting pad with only a lower portion of the inking pad and in a narrow zone adjacent the outer ink delivery surface of the inking pad, delivering ink from the reservoir to the inking pad only adjacent the outer portion of the inking pad at the contact with the ink conducting pad, and conveying ink upwardly of said inking pad by capillary action to the ink delivery portion of the inking pad. 17. A method in accordance with claim 16 in which the inking pad is a tube surrounding the hub, and in which the ink conducting pad is a washer-like pad that is cocked-up at its outer periphery to contact and deliver ink to the inking pad in a narrow band of contact therebetween near the outer periphery of the ink conducting pad. 18. A method in accordance with the claim 16 including contacting an ink receiving means with the inking pad to deliver ink to said ink receiving means, and carrying ink away from the inking pad on said ink receiving means. 19.
