First. The set-off of the first side. Devices were used to overcome this and the ink-makers were induced to pay special attention to the manufacture of rapid-drying or non-setting-off inks. Second. The difficulties in obtaining paper in the roll of uniform perfection and strength. The paper-makers were led to make a study of producing large rolls of paper meeting these requirements, and became much more experienced in its manufacture. The “Walter” press in the “Times” office had necessitated a very strong and expensive paper, which could not be afforded by the cheap daily press. Third. The difficulty of the rapid severing of the sheets after printing. Fourth. A reliable and accurate delivery of the printed papers. These last two operations were not accomplished satisfactorily until the appearance of the Hoe machine. In this press the sheets were not entirely severed by the cutters, but simply perforated after the printing. They were then drawn by accelerating tapes, which completely separated them, onto a gathering cylinder so constructed that six perfect papers, or any other desired number, could be gathered one over the other. These, by means of a switch, were at the proper moment turned off onto one sheet flier, which deposited them on the receiving board. This gathering and delivery cylinder, patented by Stephen D. Tucker, a member of the firm of R. Hoe & Co., solved the problem of rapid flat delivery. The first of these machines was placed in the office of “Lloyd’s Weekly Newspaper,” in London, and the first one used in the United States in the “Tribune” office in New York. There was no limit to their capacity for printing excepting the ability of the paper to stand the strain of passing through the press, which produced, when put to its speed, 18,000 perfect papers an hour, delivered accurately on one feed-board. The average speed, however, in printing offices was 12,000, although in some offices they were run at about 14,000 per hour. The “Walter” press, made by the London “Times,” was used by it, and also by the London “Daily News” and by the New York “Times.” Further than that it made no progress and has now gone entirely out of use, the presses of this kind in the London “Times” office having been replaced by machines made by R. Hoe & Co. Meantime their machines were adopted by most of the large newspapers in the United States and Great Britain. These new methods, of course, entirely superseded the “Hoe Type Revolving Machine,” which had reigned supreme in the newspaper world for over twenty years, and of which one hundred and seventy-five had been made, almost all of which have now disappeared.
