is fed from three rolls of paper and can print, cut. pate. fold, and count 24.000 papers of 14. 20, or 24 pages each, 36,000 papers of 16 pages each. 48,000 of 10 or 12 pages each, and 72,000 of 8 pages each during every hour of its daily operation. In 1900 three oetuple presses were installed for the New York Journal. Each press weighs, when in running order, about 200,000 pounds. and has 11 pairs of printing cylinders. 40 ink-distributing cylinders• 100 com position rollers. 22 ink fountains, 5 sets of oil fountains, and 850 gear wheels.
These presses are operated by electricity, and are 35 feet long. 10 feet wide, and 15 feet high. An SO horse-power electric motor is required to start one of them front a state of rest until it attains its proper speed, after which it performs its work at a considerably less expense of power.
In these machines five-cylinder color presses are combined with a full black press, which also has extra facilities for turning out fine newspaper work from electrotype plates; con sequently half-tone plates and colored illustra tions can be printed in connection with the text.
In 1903 a press of -till greater dimensions was In this construction a large central cylinder contained the form of type on a small portion of its circumference, the rest of that circum ference being used for the movement of inking rollers. The types were held in place by grooved and rebated column rules and screw clamps. Around this large cylinder were placed at grad uated distances 4, 6, S, or 10 impression cylin ders. for each of which separate piles of paper and separate feeders had to be provided. Every revolution of the central cylinder produced from four to ten copies. but these copies were printed on one side only. and this defect limited its
value as a newspaper machine. In 1571 R. Hoe S. Co. invented a rotary pre—. which printed on both sides. front curved stereotype plates at the rate of 12,000 an hour. This machine, a favorite at the start. has been recon-truc•ted on new lines with many improvements for the different requirements of eight-page or forty eight-page newspapers. Two or more distinct machines are geared together in one constrnetion and are known as the quadruple, sextuple, and oetuple machines.
A sextuple press built for the New York Herald in 1889 is composed of about 16.000 pieces and weighs 116,000 pounds. This press constructed by R. Hoe & Co., which uses when running at full capacity, eight rolls of paper, each four newspaper pages wide. This machine re quires 125-horse power to drive it, and when run ning at its full capacity consumes in an hour about TO miles of paper, the width of the roll, or 280 miles of paper of the• width of the newspaper page. In addition to the eight rolls of paper already mentioned eight other rolls are in posi tion. so that when any of the rolls run out the roll-carrier may be turned on a turntable, and the new roll of paper quickly pasted to the end of the depleted roll. The running speed of this press is 96.0o0 papers an hour, four, six• eight, ten, twelve, fourteen or sixteen pages, or 48, 000 eighteen, twenty, twenty-two, twenty-four, twenty-six, twenty-eight, thirty, or thirty two page papers, all delivered, folded to pare size, pasted, and counted. Other rotary presses of merit are made in this country, and in France and Clermany, but they contain no distinctive principle that calls for minute description.
