The accompanying cut represents our new presses !
A horizontal cylinder, Of about four aud h.lf feet
in diametsr,is mounted ON shaft with appropriate
bearings; about one-fourth OF the circumference OF
this cylinder constitutes the bed OF the PRESS the
periphery of which Is adapted to receive the form
of types-the remainder Is used as cylindrical dis
tributing table. The diameter Of this part of the
cylinder 10 less than that Of the form of types that
1t may pass by the impression cylinders without
touching them. In one Of our presses the ink is
taken from a fountain placed beneath the large
cylinder from which 1t is taken by ducter roller
and transferred by vibrating distributing roller to
the cylindrical distributing table; the fountain
roller receives slow and continuous rotary mo-
ton, to carry up the ink from the fountain. In the
other press, instead of the stationary fountain there
is small fountain placed at the circumference of
the large cylinder behind the type. and revolving
with IT., which supplied with Ink from reservoir
placed in the upper part of the rame the ink being
conveyed through pipes to and through the Jour-
mails Of the main shaft Of the large cylinder to the
small fountain.
The large cylinder put in motion the form of types

pondng horizontal impression cylinders, arranged
at proper distances around It, to give impression to
four sheets, introduced one by each cylinder. The

The four pages are put to press at the same time,

with the shafts of the cylind.-, and are conse-

OF the cylinder, 90 as to bind the types near the

rules were also parallel, matter how tight they

they can be on the old flat bed.
Each OF our presses at their ordinary speed, will
PRINT 1000 Impressions per hour, and can readily be
driven, on an emergency. to 10000 impre per
hour. They each require four boys TO feed In the
sheets, and at present, tour bows to receive them
when printed but the latter intend to dispense
with, as we are having machinery made to fly the
sheets by the ordinary operation of the presses.
Each press occupies space of IL feet long, feet
wide and 10 feet high.
A press with eight impression cylinders of this
construction, will print 5000 impressions per
hour
THE PRINTING MACHINERY OF TIE LONDON TINES.
From the London Times, Dec 20
Twenty years ago we noticed IN these columns
a printing. machine designed and constructed for
US by Mr.. Augustus Arplegath, OF hartford. 1t was
then thought Impossible to improve on the plan,
and though our sheet has long since been doubled
and Its sale more than quadrupled, we have ever

engineer for al invention of much greater power.

who are unacquainted with printing machinery

enabled TO PRINT The Times at the rate of nearly
l40lmpressions per minute.
the reader will unfold this sheet to its full SIZE
he will observe that on each side there are four
pages, containing altogether twenty-four columns.
In the ordinary steam press the type prepared for
the printing OF this immense surface is securely
wedeed IN one iron frame, whlce Is laid on table
traversing species OF railroad nine or ten feet
long. As the table moves backward and for.
wards the type laid upon it passes under four cy-
finders, covered with woollen cloth, and placed
croesways over the "railroad." These are called
"the printing cylinders" 1t Is bv their pressure
impression is produced. The sheets of paper,
previously stamped at Somsrset-house, and then
damped in this office, are conveyed to the four
printing cylinders by means of endless tapes from
four flat tables, or "laying-on boards" Any one
who has seen how a common thrashing machine
10 ted with successive handfuls from the rick will
easily understand how the successive sheets of
paper are supplied to the printing-machine, and
The cylinders are so arranged that two act upon
passage to the left. Other smaller cylinders, or
rollers" similarly disposed across the path Of the
ype, supply 1t with ink. The sheets, as they pass
round the printing cylinders, are pressed upon the
meving type, and receive Its impression. They |
are then carried y endless tapes to the hands Of
persons, two - each side OF the machine, who re-
ceivs then; and pile them on the /" taking-off
boards" The paper thus printed on one side 10

on the other side by similar operation.
