45 x 65 inches. Resting upon and attached to a heavy iron foundation
are two iron side frames which are securely braced together by an
upper iron frame, called the "rib." This upper frame contains four
tracks faced with hard steel, on which run a series of friction
rollers, supporting the iron type-bed. Attached to the front of the
type-bed is an iron plate, called the ink-table, its surface level
with the surface of the type-form as it lies upon the bed.

At the front of the press is the ink-fountain and a number of steel
and composition rollers, called the "distributing rollers." The ink is
delivered a little at a time from the fountain to the revolving
distributing rollers, and from them to the ink-table which moves under
the rollers with the motion of the type-bed. By this means the ink is
distributed upon the entire surface of the ink-table in a thin, even
film. From the ink-table the ink is taken by a set of six rollers,
called the "form rollers." Resting on the form rollers and moving in
contact with them are additional rollers which help to distribute the
ink still finer before it reaches the type.

The impression cylinder is located at a distance from the front of the
press of about two-thirds of the entire length of the press. The
circumference of the cylinder is equal to the distance that the
type-bed travels in one direction. When the type-bed moves from the
front to the rear, the cylinder rotates in unison with it, and thus
the cylinder makes one revolution. While the bed returns the cylinder
does not move.

Near the rear of the press is a large wooden board extending across
the press and lying in a slightly inclined position with its lower
edge almost directly above the centre of the impression cylinder. This
is the "feed board" upon which the sheets of paper lie before they are
printed. The impression cylinder has a set of grippers, and when the
cylinder is at rest, these grippers are close to the edge of the feed
board and stand open to receive the edge of the sheet of paper.
Extending a little over the front of the feed board are two gauges
against which the front edge of the sheet of paper is placed, while
one side edge of the sheet is placed against a gauge at the side of
the feed board. Just an instant before the cylinder commences to
rotate, the grippers seize the front edge of the sheet, and the gauges
lift out of the way. The cylinder then carries the sheet around, meets
the moving inked for
