two small rollers, a a', advance over the rack, N, and the sheets,
instead of continuing to roll over into the accumulator, fall on the
rack and are deposited by it upon the receiving table, O.

[Illustration: FIG. 2.--MARINONI'S PRESS.]

The rack having fallen twenty times, and deposited five sheets each
time, or one hundred in all, the table moves in such a way as to prevent
the sheets subsequently deposited from getting mixed with them. When the
rack has fallen twenty times, the table returns to its initial position.

The distributing rollers, D, come in contact with the inking rollers, I,
once during each revolution of the printing cylinders, and are mounted
on racking levers provided with regulating screws that permit of easily
regulating the amount of ink taken up. The supports of the inking
rollers are movable and can be made to approach or recede from the
distributing rollers, so as to still further vary the amount of ink
taken up by them.

The distributing rollers supply the ink to a roller, E, of large
diameter, which, having a backward and forward motion, begins to
distribute the ink and to transmit it to a second roller, F, of the same
diameter. This latter then spreads it over a metallic cylinder, G, which
is of the same diameter as the printing cylinders, and against which
revolve three distributing rollers, H, that have a backward and forward
motion.

Between the cylindrical inking table, G, and the type cylinder, there
are situated inking cylinders, T, of large diameter, that constantly
