About 1876 Messrs. Anthony & Taylor of England (the former one of the owners of a newspaper in Hereford) took out patents for devices by which the webs of paper could be turned over after printing on one side and the opposite or reversed side presented to the printing cylinder. Mr. Hoe, who was in England at the time, appreciating the possible use and development of these patents, became possessed of them for England and the United States. E. L. Ford, engaged in the publication of a newspaper in New York, patented the uniting of the product of two or more printing mechanisms and thus producing (in restricted form) a multiple number of pages at one time. He was unable, however, to develop his plans to any practical result; but deserves the credit of being the first to patent, if not to conceive, the idea of the association of printed sheets for this purpose. [Illustration: DOUBLE SUPPLEMENT PRESS] In the various experiments of Hoe & Co. bearing upon the manipulation of webs of paper some of their devices appeared to encroach upon patents secured by Luther C. Crowell, inventor, of Boston, who had made an ingenious machine for forming paper bags. These patents were immediately secured by purchase and the experimental work proceeded with the view of adapting some of them to the requirements of the printing press. After many efforts, and the failure and destruction of several machines which had been constructed at great expense, the Hoe “Double Supplement” machine was produced, the first one being purchased by James Gordon Bennett of the New York “Herald” and put to work in his office. The result of these efforts has been, for a third time, a complete revolution of the methods of fast newspaper printing. The most remarkable features of this machine are: Its extreme simplicity, considering the varied work it performs, and its great speed, accuracy and efficiency. It turns out either four, six, eight, ten or twelve page papers at 24,000 per hour, and sixteen page papers at 12,000 per hour; the odd pages being in every case accurately inserted and pasted in, and the papers cut at top and delivered folded. This machine is constructed in two parts, the cylinders in one portion being twice the length of those in the other; the short cylinders being used for the supplements of the paper when it is desired to print more than eight pages. The plates being secured on the cylinders, the paper enters from the two rolls into the two portions of the machine, through each of which it is carried between the two pairs of type and impression cylinders, and printed on both sides, after which the two broad ribbons or “webs” pass over turning bars and other devices, by which they are laid evenly one over the other, and pasted together. The webs of paper then pass down upon a triangular “former,” which folds them along the center margin. They are then taken over a cylinder, from which they receive the final fold, a revolving blade within this cylinder
