After setting the frame upon its legs, and putting on the ribs and bed, lay the platen on the bed, placing under it two bearers about type high. Then put the springs in their places, and the nuts over them, and pass the suspending-rods through them, observing to place the rods so that the number of indentations on them correspond with those on the platen. Give the nuts two or three turns, then run in the bed so as to bring the platen under the rods, and screw them fast to the platen; after which, put in the bar-handle, standard, and lever, (or wedge and knees, if a Smith press.) Turn the nuts on the suspending-rods, so as to compress the springs just enough to give the platen a quick retrograde motion, observing at the same time to get the surface of the platen parallel with the surface of the bed. After having put the press together and levelled it by means of a spirit-level, be particular not to raise the end of the ribs by the gallows, but let it go under rather loose, which will have a tendency to make the bed slide with more ease on the ribs. SETTING UP THE ROLLER-STAND. The roller-stand containing the distributing cylinder should be regulated to the height of the press, bringing the shelf or bridge even with the corner irons, and at sufficient distance from the bed to allow it to run clear; the stand should then be firmly braced, as the constant turning of the rounce is very apt to loosen it; meanwhile being cautious to observe that the rounce, in its revolutions, does not come in contact with the frame of the tympan when up. The position of the distributing cylinder should be sufficiently high to allow the two composition rollers, at least one inch apart, to rest on its top without danger of touching the shelf or bridge in front. It is advantageous to nail two narrow strips of sole leather on the face of the shelf, about eight or ten inches from each end, which, acting as bearers, cause the rollers to pass very smoothly over them. [Illustration: ROLLER STAND.] The roller-handle while in use should lie in a horizontal position, the back end being supported by a bar of wood or iron running parallel with the distributing cylinder. There should be a notch, or hook, about two inches from the end of the handle, to catch on the wooden supporter, to prevent the rollers from jumping forward while distributing or changing. It is also necessary to have a back-board for the end of the roller to strike against in coming off the form, to prevent the rollers from falling backward. The ink-block is placed about five or six inches to the right of the roller-handle, and about on a level with it. It is furnished with the ink-slice, and a brayer, or a small roller about four or five inches long, and of the same circumference with the larger rollers, being cast in the same mould.
