Description
Washburn's patent "consists of a series of light folding-frames hinged on the top of a table, and provided with operating-gear actuated by a cam-shaft, which said frames are arranged in such order and sizes relatively to each other that a printed sheet delivered on the table over all the folding-frames by the depositors of a printing press will be folded in the order of folding it by hand and thrown off the machine by another frame similar to the folding-frames, the said machine being operated in a peculiar way by the printing-press from which it receives the sheets as they are printed..."
