[Illustration: THE BULLOCK SELF-FEEDING PERFECTING PRESS, WITH FOLDER, WILL FLY THE SHEET FLAT, FOLD IT THREE OR FOUR TIMES AT WILL, OR CUT, FOLD, AND PASTE IT AS FAST AS PRINTED] Mr. Bullock, born in Greene County, New York, was a mechanical genius, and was the author of many inventions in various departments of machinery.[18] About the year 1860, he began to work out the idea of a rotary self-feeding, or web perfecting press. After making a large working model, which is still in existence, he adopted a simpler plan, and in 1861 constructed a machine for the _Cincinnati Times_, which was successfully operated, but it was far from perfect. Three of these machines were used for a considerable time in the office of the _Philadelphia Inquirer_. He continued his efforts, and in 1865 he produced a press which met his original anticipation, and a company was formed to manufacture it. In 1867, while setting up a machine for the _Public Ledger_ in Philadelphia, he suffered a serious injury which terminated his life. More than fifty of the presses are now in use in the United States. The New York _Herald_ press, printing and cutting two copies at each delivery, is said to produce, with but three men to attend to it, 30,000 copies per hour. The New York _Sun_ states: “When our seven Bullock Presses are working, we can turn off, without extravagant assertion, 210,000 copies an hour.” This assertion must be taken with some grains of allowance. The press is twelve feet long by five and a half feet wide. THE WALTER PERFECTING PRESS. The Bullock press was not long allowed to be the only press for rapid printing from cylindrical stereotype plates fed by a so-called endless roll of paper. The principle was applied to a machine constructed in the London _Times_ office, called, after the name of its celebrated proprietor, the Walter press. This appears to be an effective press, but it seems more complicated than either the Bullock or Hoe machine, and from its mode of delivering the sheets, it is excessively noisy. The New York _Times_ was printed on it at the Centennial Exhibition in Philadelphia. THE HOE PERFECTING PRESS. The enterprise of R. Hoe & Co., of New York, soon gave birth to a web perfecting press combined with a folding machine that answers every requirement. [Illustration: THE HOE WEB PERFECTING PRESS.]
