With this department, the survey of the Broome street manufactories and saw-works is terminated. The Gold street establishment is principally applied to the storing and exhibition of all the various articles coming under the head of letter-press, compositors’, warehouse, welting, and bookbinders’-tools departments—and here is kept ready, at a moment’s notice, a large assortment of hand-presses, copying-presses, ruling, cutting, and piercing machines, in great variety and equal excellence, of all prices. In this building, moreover, are manufactured the beautiful and excellent vertical steam-engines from five horse-power, 6 inch cylinders, and 10 inch stroke, up to fifteen horse-power, 11 inch cylinders, and 22 inch stroke, the largest of which are in use in the Herald, Tribune, and Sun offices, for putting in motion the large fast printing machines, by which those largely circulated journals are thrown off daily in huge editions with unparalleled rapidity. Here also are built the portable steam-engines from 3 to 4 horse-power, with vertical tubular boilers; and the hydrostatic presses, for the finishing of printed sheets, which have come into so general and wide a field of operation within the last few years. The following is a correct and beautifully finished representation of the great fast printing eight-cylinder machine in the vault of the Sun office in full operation; without which the end and object of this paper would be incomplete. This immense printing machine is 33 feet long, 14 feet 8 inches high, and 6 feet wide. It has one large central cylinder, on which the type is secured, and eight smaller cylinders arranged around it, at convenient distances. Eight persons supply the eight small cylinders with the sheets, and at each revolution of the large cylinder eight impressions are given off, the sheets being delivered in neat order by the machine itself. The limit to the speed is in the ability of the eight persons to supply the sheets. At the rate of 2,500 sheets to each, the press would give off the unparalleled number of 20,000 printed impressions per hour. The press is used exclusively for newspapers, or similar printing. [Illustration: =LARGE FAST PRINTING PRESS.=] The principles and operation of this wonderful invention are thus conclusively and laconically described in Messrs. Hoes catalogue mentioned above, which we annex, without alteration, for reasons heretofore assigned, and to which we can add nothing beyond the expression of our sincere and earnest admiration.
