Few quite satisfactory methods of re-inking typewriter ribbons are known. By a simple method, the ribbon is stretched and drawn over a bottle, the ink being brushed on as the ribbon passes. Use only a little ink and apply it to but one side of the ribbon. Another method would be to pass the ribbon between two pads, oue or both of which could be inked. Or if many ribbons were to be dealt with, a frame carrying two felt-covered rollers could be constructed. One roller could he turned by a crank, the necessary motion being conveyed to the other roller by friction. An arrangement could easily he made hy means of which the rollers could be supplied with ink, and the ribbons could then he inked easily by merely passing them between the rollers.
