Brown's patent says that "heretofore the coloring-matter has been applied to the paper by hand, or a device has been used for applying it to any side of an endless sheet of paper by means of a roller revolving in a reservoir of coloring-matter, which is taken from the roller and applied to one side of the paper by a circular brush." His improvement rapidly applies "the coloring-matter to both sides of a sheet or paper, or to one side of each of two sheets placed together for that purpose." (Patent Number 85,426)
