A. F. Bauer, another German, secretly made
a press which applied the pressure by a
cylinder instead of flat surface, and on
Nov. 28Gh, 1914, 1.-THE London Times" in
formed the public that they were now read
ing paper printed by steam power-the
first ever printed in that way. In this press
the type was made to move horizontally
under printing cylinder. The ink was
placed in a cylinder in front ofth printing
one, and received, distributed and applied
by rollers. This press was further improv-
ed by placing printing cylinder on each
side of the mixing rollers, thus getting ca
pacity to print two copies instead of one.
This press could then print 1900 copies
per hour Mr.. Konig's linking apparatus,
however, was far from being perfect, TAX
ing sometimes two hours to start it correct
ly.
In 1915 MIR. Cowper patented a process
for curving stereotype plates and fastening
them on cylinder. He also patented an
linking table. Several distributing rollers
were disposed under the type cylinder, in
such manner as to come successfully in
contact with the type and with part of
the cylinder used as distributing table.
The ink was taken from the fountain to
the table by another set of rollers. A few
of these machines were built for and used
by the Bank of England.
The next improvement was made by
Cowper & Applegarth, and consisted in
applying the distributing table to flat
bed press. These machines were very sue
cessful and are now used, with slight al
teration, all over the world.
While Englishmen were perfecting CYL
inder presses Isaac Adams, of Boston, Mass,
took up Konigs idea of working hand
press by steam, and succeeded in inventing
what is known as "The Adams Press" The
platen is stationary; the bed, situated di-
rectly under the platen, has an up and
down motion of a few inches; in front of
the bed is large mixing roller revolving
constantly while the press is working, the
tympan has horizontal motion and car
ries an linking roller which at each stroke
comes in contact with the large roller and
then rolls back over and inks the type.
The tympan is also provided with iron fin
gers which grab the edge of the paper and
carry it between the the bed and platen.
The printed sheet is carried by tapes be-
tween which the edge is blown by an air
pump. The sheet is then taken from the
tapes and laid down by fiy-a fork of light
wood and carried on rocking shaft.
To this press there is a pedal, which upon
pressure from the foot OF the feeder, discon-
meets the rod which joins the bed with
the main shaft, thus avoiding back prin-
ting. This machine is worked at three diff
terent velocities and averages 900 copies
per hour.
In 1S47 Richard M. Hoe, of New York,
made the first successful type-revolving
press, and in doing so availed himself of
all improvements from the time of Nichol-
son, viz the gelatine rollers the distribut-
ing table; the fly; and all the different
processes of working metal and building
machines in general. The large "Hoe
Press consists of horizontal cylinder,
of great size and weight, upon which the
type is held, and of from four to ten print
ing cylinders, which are arranged around
the first and tangential to it. The type
cylinder and the printing cylinders re-
connected by gearing in such manner
that their velocity at the circumference is
exactly the same. Each printing cylinder
is cut longitudinally and iron fingers pro-
ject through the slit taking hold of the
paper and letting go of it at the proper
moment. Uuder the type cylinder are the
linking fountain and distributing rollers,
and between the printing cylinders are the
mixing rollers. The printing cylinders are
fed by hand; the paper is caught by iron
fingers and made to roll around the print
ing cylinders and by revolving in contact
with the type cylinder receives the i'm
preston of the type. 1t is then caught by
tapes and laid down by the flies. The
largest Hoe presses, used in New York,
London and elsewhere by the leading
dailies, are capable of printing from $4,000
to $4,000 impressions per hour.
IL 1853, DR.. S. w. Francis, Of New York,
inV.nted press for the use of the blind.
1t consists of keyboard, each key acting
on hammer on which letter is engraved.
The letters arc printed in two movable
sheets of paper-thus producing two cop
les at once.
Machines have been invented for setting
and distributing type, and, although they
have considerable merit, yet they have
been generally pronounced impracticable.
