page_text: ducting the printed sheets to one or other end of the machine to receivers d, d¹,
which deliver them on the tables e, e¹; 4thly, the combination and arrange-
ment of the tapes for conducting the printed sheets to the four mechanical
receivers; 5thly, the mode of inking the types by the aid of the mechanism
G, G', either with two inking rollers i, j, acting alternately during each revo-
lution of the type cylinder, or with two rollers acting continuously; 6thly, the
application in said machine of a movable inker i for increasing or diminishing
the supply of ink. which is regulated by a screw it as desired; 7thly, the appli-
cation to cylinder printing machines with drawing-off gear of four receivers d;
8thly, the application to said cylinder printing machines of inking and distri-
buting rollers, j, k, l, covered in leather or other suitable material.
ACTION OF THE APPARATUS.
In order to print in this machine the sheet is fed by hand from the table l³,
when it is seized by a part n covered with india-rubber, which is brought in
contact with the feed roller a² by means of a lever m² actuated by the
excentric; the sheet is then carried along by the tapes q between the lower
feed rollers a³, a', which are furnished with similar tapes q' for conducting
the sheet to the rollers a, a. The sheet held between the tapes r, s, thence
passes between the cylinder g, carrying the type and the pressing cylinder b
covered with some soft material as usual, the sheet being printed on the one
side by passing between the said cylinders. The rotary motion continuing
the sheet is conducted by the tapes r, v, to the pressing cylinder b', which in
its motion carries round with it the sheet and causes it to take an impression
from the type cylinder g'. The sheet thus printed on both sides is then
conducted to the mechanism A by the tapes u, x, 2, whence by the aid of an
excentric operating the rollers c the sheet is dispatched either to the right or
left of the machine by the tapes g, g¹. The sheet arriving either at point
B or B is conducted by the tapes for f to the receivers d or d for deli-
very on the tables e or e¹. The mechanism C, C', supplies ink by the aid of
the roller from the adjustable inker i to the inking cylinders D, D', on
which it is evenly distributed by the rollers, which have a longitudinal to-and-
fro motion imparted by an excentric simultaneous with their rotary motion.
The inking of the types or characters is effected by the two rollers . ', which
are fitted so as to touch the inking and type cylinders either alternately or
continuously. The progress of the sheet from either of the other tables h', h³,
h, h, h, is the same as that described with reference to table h².

mechanism G, G', either with one or with two inking rollers i, j, during each
revolution of the type cylinder, or with two rollers acting alternately; sixthly,
the application in said machine of a moveable inker i for increasing or dimi-
nishing the supply of ink, which is regulated by a screw i¹ as desired; seventhly,
the application to cylinder printing machines, printing on both sides of the
sheet, of four receivers d, d¹; eightly, the application to said cylinder printing
machines of inking and distributing rollers i, j, k, l, covered in leather or other
suitable material.
ACTION OF THE APPARATUS.
In order to print in this machine the sheet is fed by hand from the table
in readiness to be seized by a metal part n covered with india-rubber, which
is brought in contact with the feed roller by means of a lever m³, actuated
by the eccentric t; the sheet is then carried along by the tapes q between
the lower feed rollers a³, a', which are furnished with similar tapes q' for
conducting the sheet to the rollers a, a. The sheet held between the tapes
r, s, thence passes between the cylinder g carrying the types or stereotype,
and the pressing cylinder b covered with some soft material as usual pressing
on g, the sheet being printed on the one side by passing between the said
cylinders. The rotary motion continuing the sheet is conducted by the tapes
r, v, to the pressing cylinder b', which in its motion carries round the sheet,
causing it to take an impression from the type cylinder g'. The sheet thus
printed on both sides is then conducted to the mechanism A by the tapes
v, a, 2, where by the aid of an eccentric operating the rollers c, the sheet is
dispatched either to the right or left of the machine by the tapes g, g. The
sheet arriving either at point B or B' is conducted by the tapes for to
the receivers or d¹ for delivery on the receiving tables e or e¹. The
mechanism C, C, conducts the roller from the adjustable inker i to the inking
cylinders. D or D', on which it is evenly distributed by the rollers k, which
have a longitudinal to-and-fro motion imparted by an eccentric simultaneous
with their rotary motion. The inking of the type or characters is effected by
the two rollers i, j, which are fitted so as to touch the inking cylinder D or D
and type either alternately or continuously by the aid of levers G, G¹. The

page_text: Having described the nature of this Invention, and the manner of performing
