page_text: Fig. 6 & 7, horizontal and vertical diagram of parts which throw the
printing cylinder into gear and disengage it..
In Fig. 1 the arms of the fly wheel are partly omitted. Figs. 4 to 7
are drawn on double scale.
The different parts of the press are:-a, foundation plate; b, side face
for plumber block and framework; c, feed table; d, take-off table;
e, axle of driving wheel and fly wheel; f, ink block with adjustable ink
roller; 9, 9', g, ink, rollers for the lower inking apparatus; g, roller
which takes the ink from f; g', roller which distributes the ink;
9, roller which distributes and transfers from the lower inking appa-
ratus on the cylindric ink table of the great cylinder; h, eccentric for
the vertical motion of the lower inking mechanism and for the motion
of the rollers in the ink bench and the buffer; i, spear, lever, and ratchet
wheel for the motion of the ink roller in the ink trough; k, hanging
frame of the lower inking apparatus; 7, lever for the collards of the
lower inking apparatus; m, lever for the horizontal motion of the ink
roller gn, sliding pillow for the superior wetting and inking rollers;
o, damping rollers with loose pulley; p, inking rollers; 9, printing
cylinder for conducting and delivering the paper before, during, and
after printing, worked by grippers inside of the circumference of the
cylinder; ", cylinder carrying the printing surface. The printing
surface plate, or stone, or stereo must coincide with the surface of the
cylinder.
In cases in which plates are used the cylinder has at intervals.cor-
responding with the length of the plate to be employed longitudinal
slots for purpose of receiving off the rulers after mentioned. Now the
plate is attached to the cylinder in the following manner :-'
-The plates
in the first instance have their ends bent at an angle of nearly 135°. In
the portion of the plates which is turned down holes are made at regular
distances, and the plate thus prepared is ready for insertion in the
cylinder. The attachment to the cylinder is effected by means of two
rulers, one at each end of the plate, the ruler carrying points cor-
responding to the holes in the plates. Each ruler is fitted with screws,
and these being fixed the printing surface is ready for use.
The rapid exchange of plates this system allows is not applicable to

The frontal side of the cylinder forms a broken bevelled surface,
producing the horizontal motion of the inking roller g"; besides, there
is in this frontal part a mortise b, b, which serves as a self-acting slot
hole for gearing and ungearing the cylinder q. 8, double crank and
wheel on the prolonged axe of the cylinder; t, lever having its fulcrum
in the eccentric sheave h, and serving to give the cylinder q a noiseless
passage from rest to motion; u, lever for the motion of the grippers and
stopping apparatus for the cylinder q; v, loose disk guiding the pulleys
of the grippers; w0, stopping lever; x, moveable guiding pulley for
ungearing the cylinder q; y, lever apparatus for sliding the pulley:x;
.2, sliding clutch of a coupling box fixed on the axe of the cylinder q.
The special.feature of novelty of the described printing machine is the
engaging apparatus of the printing cylinder, the mode of gearing and
disengaging the working parts of printing, effected as well by the clutch
in Figs. 6 & 7 as by the buffer in Fig. 4.
The most rapid motion of the machine will not give occasion to any
shock.
I claim therefore not only the novelty of the whole machine as well
for letterpress as for lithographic purposes, but I claim especially as a
novelty the described mode of attaching plates to the cylinder so as to
admit of their rapid removal, and the stopping and starting gear con-
nected with the pressing cylinder, which enables the machine to be
stopped and started without a jar or shock for all printing presses,
whether the same effect their printing byʻplain or circular surfaces..

Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Julius Friedlaender, Her special licence that I, the said
Julius Friedlaender, my executors, administrators, and assigns, or such
others as I, the said Julius Friedlaender, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "AN IMPROVED PRINTING PRESS," a com-
munication to me from abroad by Peter Korfitz Moeller, at Leipsic,
Prussia, upon the condition (amongst others) that I, the said Julius
Friedlaender, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Julius Friedlaender, do hereby declare
the nature of said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:-
The construction of the printing press is shown by the accompanying
Drawings.

In Figure 1 the arms of the fly wheel are partly omitted. The
- Figures 4 to 7 inclusive are drawn in double scale.
The different parts of the press are:--a, foundation plate; b, side face
for plumber block and framework; c, feed table; d, take-off table;

ink roller; g, g³, g", ink rollers for the lower inking apparatus ; 9,
roller which takes the ink from f; g', roller which distributes the ink;
g", roller which distributes and transfers from the inferior inking appa-
ratus on the cylindric ink table of the great cylinder; h, eccentric for
the vertical motion of the lower inking mechanism and for the motion
of the roller in the ink bench and the buffer; i, spear lever and ratchet
wheel for the motion of the ink roller in the ink trough; k, hanging.
frame of the lower inking apparatus; 1, lever for the collards of the
lower inking apparatus; m, lever for the horizontal motion of the ink
roller g; n, sliding pillow for the superior damping and inking rollers;
o, damping rollers with loose pulley; p, inking rollers; q, printing
cylinder for conducting and delivering the paper before, during, and.
after printing, worked by grippers inside of the circumference of the
cylinder; r, cylinder carrying the printing surface. This printing
surface plate, or stone, or stereo must coincide with the surface of the
cylinder.
.
In cases in which plates are used the cylinder has at intervals cor-
responding with the length of the plate to be employed longitudinal
slots for purpose of receiving off the rulers after mentioned. Now the
plates are attached to the cylinder in the following manner:-The plates
in the first instance have their ends bent at an angle of nearly 135°. In
the portion of the plate which is turned down holes are made at regular
distances, and the plate thus prepared is ready for insertion into the
cylinder. The attachment to the cylinder is effected by means of two
rulers, one at each end of the plate, the rulers carrying points cor-
responding to the holes in the plates. Each ruler is fitted with screws,
and on these being fixed the printing surface is ready for use.
The rapid change of plates this system allows is not applicable to
stone or stereo plates, which must be fixed in the usual way.
The frontal side a, a, of this cylinder forms a broken bevelled surface,
producing the horizontal motion of the inking roller g"; besides, there
is in this frontal part a mortise, which serves as a self-acting slot hole
for gearing and ungearing the cylinder q. 8, double crank and wheel on
the prolonged arc of the cylinder; t, lever having its fulcrum in the
eccentric sheave h, and serving to give the cylinder q a noiseless passage
from motion to rest; ", lever for the motion of the grippers and stopping

grippers; w, stopping lever; x, moveable guiding pulley for ungearing
the cylinder q; y, lever apparatus for sliding the pulley x; %, sliding.
clutch of a coupling box fixed on the axe of the cylinder q.
The special feature of novelty in the described printing machine is the
engaging apparatus of the printing cylinder, the mode of gearing and
disengaging the working parts of printing effected as well by the clutch
in Figures 6, 7, as by the buffer in Figure 4.
The most rapid motion of the machine will not give occasion to any
chock.
I claim not only the novelty of the whole machine as well for letter-
press.as for lithographic purposes, but I claim especially as a novelty,-
1. The engaging apparatus of the printing cylinder, i. c., the mode of
gearing and disengaging the working parts, effected by a clutch and a
buffer.
2. The mode of attaching plates so as to admit of their rapid
removal.

In witness whereof, I, the said Julius Friedlaender, have hereunto
set my hand and seal, this Twenty-second day of December, in
the year of our Lord One thousand eight hundred and seventy- 2
three.
