The ink is contained in a fountain placed beneath the main cylinder, and is conveyed by means of distributing rollers to the distributing surface on the main cylinder. This surface being lower or less in diameter than the form of types, passes by the impression cylinders without touching them. For each impression there are two inking rollers, which receive their supply of ink from the distributing surface of the main cylinder, and raise and ink the form as it passes under them, after which they again fall to the distributing surface. Each page of the paper is locked up on a detached segment of the large cylinder, called by the compositors a "turtle," and this constitutes its bed and chase. The column-rules run parallel with the shaft of the cylinder, and are consequently straight, while the head, advertising, and dash-rules are in the form of segments of a circle. The column-rules are in the form of a wedge, with the thin part directed toward the axis of the cylinder, so as to bind the type securely, and at the same time to keep the ink from collecting between the types and the rules. They are held down to the bed by tongues projecting at intervals along their length, which slide into rebated grooves, cut crosswise in the face of the bed. The spaces in the grooves between the column-rules are accurately fitted with sliding blocks of metal even with the surface of the bed, the ends of the blocks being cut away underneath to receive a projection on the sides of the tongues of the column-rules. The form of type is locked up in the bed by means of screws at the foot and sides, by which the type is held as securely as in the ordinary manner upon a flat bed, if not even more so. The speed of the machine is limited only by the ability of the feeders to supply the sheets. Twenty-five hundred is about as many as a man can supply in an hour, and multiplying this by ten--one man being at each cylinder--we have 25,000 sheets an hour as the capacity of the press. CHAPTER XIX. SAMUEL COLT. Samuel Colt was born at Hartford, Connecticut, on the 19th of July, 1814. He was descended from one of the original settlers of that city, and his father, who possessed some means, was a man of great energy, intelligence, and enterprise. The senior Colt began life as a merchant, and afterward became a manufacturer of woolen, cotton, and silk goods. The mother of our hero was the daughter of Major John Caldwell, a prominent banker of Hartford, and is said to have been a woman of superior character and fine mental attainments.
