Chancery Lane, in the County of Middlesex, for the Invention of IM-
PROVEMENTS IN PRINTING MACHINES." (A communication from abroad
by Constant Alexis Guy, of Paris, France) bearing date 15 August, 1876,
No. 3217.
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
entered by the said Edward Griffith Brewer pursuant to the Statute in
that save made and provided
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
GRIFFITH BREWER, of Chancery Lane, in the County of Middlesex, send
greeting:
WHEREAS Her most excellent Majesty Queen Victoria by Her Letters Patent
under the Great Seal of the United Kingdom of Great Britain and Ireland, the
Channel Islands, and the Isle of Man, bearing date the 15th August, 1876, and
Numbered 3217, in the Thirty-ninth year of Her reign, did for Herself, Her heirs,
and successors, give and grant unto the said Edward Griffith Brewer, his executors,
administrators, and assigns, the sole privilege of making, using, exercising, and
vending within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and the Isle of Man, the said Invention for the term of fourteen years
from the date of the said Letters Patent :
And whereas I, the said Edward Griffith Brewer, since the filing of the Specifi-
cation have ascertained that certain parts of the said Invention were known before
the date of the said Patent; also that the clearness of the said Specification in some
parts is doubtful; also that the Drawings somewhat vaguely indicate the parts
described:
NOW KNOW YE that I, for the reasons aforesaid, am desirous by and with
the leave of Her Majesty's Attorney General, to file corrected supplementary
Drawings and to make the following alterations in the Specification, vizt. :—
On page 2, line 30 of the printed Specification, after the word "Drawings" to
insert "Figures 1, 2, 3, 4, and 5." Line 43, same pago, to strike out the words
"the engraving thus prepared." Line 44, to strike out the letters from the word

stitute the word "driving" for the word "during." Line 13, to erase the letter s
from the word "wipers," and to insert after the word wipers the word "sheets."
Line 15, to erase the letter 8 from the word wipers, and to insert after the
word wipers the word "sheets;" and a similar alteration in lines 16, 18, and 19
of the same page.
To erase the first, second, third, and fourth claims, and to substitute in lieu
thereof the following claim -The employment of tampons or wiper pads, having-an.
alternate to-and-fro motion imparted to them, in combination with rollers carrying.
rags or sheets, which are caused to unroll continuously, and so to present a fresh
surface or surfaces as the impressions are produced, all substantially in the manner
and for the purposes herein-before described and illustrated in the accompanying
Drawings.
And the said Specification when altered and disclaimed reads as follows:-
This Invention is applicable to cylinder and flat printing machines.
In the accompanying Drawings, Figures 1, 2, 3, 4, and 5, two examples are shewn
illustrating the manner in which the Invention is carried into effect. Tho first
cylinder.b is driven from any suitable prime mover by means of a pinion a, and through
suitable gearing motion is communicated to a second cylinder c; the first cylinder b
is intended to draw the sheet of paper to be printed on, and the second cylinder o
carries the engraved plate. The first cylinder is provided with a clip e, so as to take
a sheet of paper at each revolution of the cylinders, and according to the speed-com-
mmunicated by the motor, so is the speed regulated at which each impression is struck
the printing and the pulling off is thus obtained.
off;
The inking is effected as follows:-An ink vessel A supplies ink to a first inking
roller e¹, which conveys it to a second roller e², which transmits it to a third and
fourth roller e and e successively, and subsequently to three other rollers es, e, and
e, which operate directly upon the engraved plate or plates on the printing roller.
The most difficult operation is the wiping; for this purpose movable tampons or
wiper pads are employed, which represent or reproduce, as nearly as possible, hand-
work, with the additional advantage of mechanical precision; they are held in
position in guides g, and the pressure is regulated by screws h. To obtain a good
wiping it is necessary to imitate the action of a skilful workman's hand, and not
that of a circular motion only.
According to one arrangement of this Invention (the wiping is double in the
circular direction) the plate to be printed from is fixed on the cylinder c, whereby
it will be drawn in a circular direction. The tampons or wiper pads freceive at
their side a horizontal alternate motions by means of an eccentric crank or other
equivalent means, as shewn at Figures 1, 2, and 4, the eccentric rod being at 8
jointed to the rod of the wiper pads, so that they have a combined double
movement and produce a curve resembling that produced by a skilful workman.
There is still another difficulty to be overcome, which is accomplished in this
machine. The wiping rags or sheets become very soon dirty, and have to be cut off
or changed in proportion to the size of the machine. According to this Invention

three or more wipers are employed, consisting of endless bands or sheets i, j, and k,
passed underneath the tampons or wiper pads f, and over cylinders i, j, and,
driven by pulleys receiving motion from a strap 1, as shown. The notion of these
wipers inay be obtained as follows:-On the printing roller shaft there is an
eccentric, Figure 1, which works a sector c³ carrying a pawl c³, which takes into
a ratchet wheel c³ on a shaft carrying a pulley, round which a strap c is passed,
which at its upper part passes and a pulley mounted on the same axis as the
pulleys c', the rollers carrying the endless wiper sheets i, j, and h; according there-
fore to the stroke given to the eccentric, and through the intervention of the
different arrangements above described, an alternate advancing movement is given
to the wiper sheets calculated according to the work to be done; supposing, for
example, the wiper sheets are 100 metres in length, and the advance is 10
millimetres for each impression, ten thousand impressions can be taken or pulled off
without changing the wiper sheets.
The wiper sheets may be made to advance at each proof, or only after two, three,
or more, but all this has to be regulated according to circumstances, as is well
known.
The wiping arrangement is applicable to flat-surfac
printing, although preference is given to the cylinders.

Figure 2 is a view of a machine constructed upon the same principle as the fore-
going, with the exception that in this instance the plate instead of being fixed upon
a continually rotating cylinder, is flat, and placed upon a reciprocating table; the
wiping and inking arrangements remain the same. A pulley A fixed upon a driving
shaft gives motion by a band C to the different parts of the machine; D is the ink
trough; and E, E, the connections to drive the rack G and printing table; J and
K are the distributing and inking roller arrangements. By means of the band I
the wipers are actuated. It will thus be seen that the machine at Figure 2 is in
principle the same as that herein-before described with reference to Figure 1.
Having now described the nature of the said Invention, and in what manner the
same is to be performed, I declare that without limiting myself to the precise forin,
size, or method of action, which may be varied without departing from the Invention,
I claim, the employment of tampons or wiper pads having an alternate to-and-fro
motion imparted to them in combination with rollers carrying rags or sheets, which
are caused to unrol continuously, and so to present a fresh surface or surfaces as the
impressions are produced, all substantially in the manner and for the purposes
herein-before described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Edward Griffith Brewer, have hereunto set my
hand and seal, this Twenty-second day of November, in the year of our
Lord One thousand eight hundred and seventy-seven.

PROVISIONAL SPECIFICATION left by the said Edward Griffith Brewer at
the Office of the Commissioners of Patents on the 15th August 1876.
EDWARD GRIFFITH BREWER, of Chancery Laue, in the County of Middlesex.
"IMPROVEMENTS IN PRINTING MACHINES." A communication from abroad by
Constant Alexis Guy, of Paris, France.
This Invention is applicable to cylinder and flat printing machines.
As an example how the Invention is carried into effect the first cylinder is
driven from any suitable prime mover, which through suitable gearing communi-
cates motion to a second cylinder; the first cylinder is intended to draw the sheet
of paper to be printed on, and the second cylinder carries the engraved plate. The
first cylinder is provided with a clip so as to take up a sheet of paper at cach
revolution of the cylinders, and according to the speed communicated by the motor
so is the speed regulated, at which each impression is struck off, this is for the .
printing and the pulling off.
.
The inking is effected as follows:-An ink vessel supplies ink to a first inking
roller, which conveys it to a second roller, which transmits it to a third and fourth
roller successively, and subsequently to three other rollers, which latter operate
directly upon the engraved plate on the printing roller; the engraving thus
prepared, the most difficult operation is the wiping, for this purpose movable
tampons are employed, which represent or reproduce as nearly as possible hand-
work, with the additional advantage of mechanical precision; they are held in
position, and the pressure is regulated by screws; to obtain a good wiping it is
necessary to imitate the action of a skilful workman obtained by the hand, and not
that of a circular motion only.
According to this Invention the wiping is double in the circular direction, the
plate to be printed from is fixed on the cylinder, whereby it will be drawn in a
circular direction; the tampons receive at their side a horizontal alternate motion,

page_text: so that they have a combined double movement, and produce a curve resembling
that produced by a skilful workman.
There is still another difficulty to be overcome in printing, which is accomplished
in this machine, the wiping rags become very soon dirty, and have to be cut off or
changed in proportion to the size of the machine; according to this Invention
three or more wipers are employed, consisting of endless rags wound on cylinders,
and driven by pulleys receiving motion from a strap. The motion of these.wipers
is obtained as follows:-On the printing roller shaft there is an eccentric, which
works a sector carrying a pawl, which takes into a ratchet wheel on a shaft
carrying a pulley, round which a strap is passed, which at its upper part passes
over a pulley mounted on the same axis as the pulley driving the rollers carrying
the endless wipers; according therefore to the stroke given to the eccentric, and
through the intervention of the different arrangements above described an alternate
advancing movement is given to the wipers, calculated according to the work to be
done; supposing, for example, the wipers are 100 yards, and I advance 10 yards for
each pull off, ten thousand impressions can be taken or pulled off without changing
the wipers.
The wipers may be made to advance at each proof, or only after two, three, or
more, but all this has to be regulated according to circumstances, as is well
known.
The wiping arrangement is applicable to flat surface printing, as well as roller
printing, although preference is given to the cylinders.

the said Edward Griffith Brewer in the Great Seal Patent Office on the 15th
February 1877.
EDWARD GRIFFITH BREWER, of Chancery Lane, in the County of Middlesex.
"IMPROVEMENTS IN PRINTING MACHINES.” A communication from abroad by
Constant Alexis Guy, of Paris, France.
This Invention is applicable to cylinder and flat printing machines.
In the accompanying Drawings two examples are shown.illustrating the manner
in which the Invention is carried into effect; the first cylinder bis driven from
any suitable prime nover by means of a pinion a, and through suitable gearing
motion is communicated to a second cylinder c, the first cylinder 6 is intended to
draw the sheet of paper to be printed on, and the second cylinder c carries the
engraved plate. The first cylinder is provided with a clip e so as to take a sheet of
paper at each revolution of the cylinders, and according to the speed communicated
by the motor so is the speed regulated at which each impression is struck off, the
printing and the pulling off is thus obtained.
The inking is effected as follows:-An ink vessel A supplies ink to a first inking
roller e³, which conveys it to a second roller e, which transmits it to a third and
fourth roller e³ and e' successively, and subsequently to three other rollers e, e", and e²,
which operate directly upon the engraved plate or plates on the printing roller;
the engraving thus prepared, the most difficult operation is the wiping for this
purpose, movable tampons or wipers fare employed, which represent or reproduco
as nearly as possible handwork, with the additional advantage of mechanical
precision; they are held in position in guides g, and the pressure is regulated by
screws h; to obtain a good wiping it is necessary to imitate the action of a skilful
workman's land, and not that of a circular motion only.
According to this Invention the wiping is double in the circular direction, tho
plate to be printed from is fixed on the cylinder, whereby it will be drawn in a
circular direction, the tampons or wipers f receive at their side a horizontal

page_text: alternate motion, so that they have a combined double movement, and produce a
curve resembling that produced by a skilful workman.
There is still another difficulty to be overcome in printing which is accomplished
in this machine, the wiping rags become very soon dirty, and have to be cut off or
changed in proportion to the size of the machine; according to this Invention three
or more wipers are employed, consisting of endless bands i, j, and k, passed
underneath the tampons or wipers f, and over cylinders i, j, and k¹, driven by
pulleys receiving motion from a strap l, as shown. The motion of these wipers is
obtained as follows:-On the printing roller shaft there is an eccentric c³, which
works a sector c' carrying a pawl c, which takes into a ratchet wheel c³ on a shaft
carrying a pulley, round which a strap co is passed, which at its upper part passes
over a pulley mounted on the same axis as the pulleys c' during the rollers
carrying the endless wipers i, j, and k; according therefore to the stroke given to the
eccentric, and through the intervention of the different arrangements above
described an alternate advancing movement is given to the wipers, calculated
according to the work to be done; supposing, for example, the wipers are 100
metres in length, and the advance is 10 millimetres for each impression, ten
thousand impressions can be taken or pulled off without changing the wipers.
The wipers may be made to advance at each proof, or only after two, three,
or more, but all this has to be regulated according to circumstances, as is well
known.
The wiping arrangement is applicable to flat surface printing as well as roller.
printing, although preference is given to the cylinders.
Figure 2 is a view of a machine constructed. upon the same principle as the
foregoing, with the exception that in this instance the plate instead of being fixed
upon a continually rotating cylinder is flat, and placed upon a reciprocating table;
the wiping and inking arrangements remain the same. A pulley A fixed upon a
driving shaft gives motion by a band C to the different parts of the machine; Dis
the ink trough; and E, E, the connections to drive the rack G and printing table;
J and K are the distributing and inking roller arrangements. By means of the
band I the wipers are actuated. It will thus be seen that the machine at Figure 2
is in principle the same as that herein-before described with reference to Figure 1.
Having now described the nature of the said Invention, and in what manner the
the same is to be performed, I declare that without limiting myself to the precise
form, size, or method of action, which may be varied without departing from the
Invention, I claim,-
First. The employment of a catch upon the feeding cylinder to engage and draw
the sheet of paper between the rollers, substantially as herein-before described and
shown.
Second. Attaching engraved plates to the periphery of a plain cylinder, sub.
stantially as herein-before described and shown.
Third. The employment of, an ink vessel provided with inking rollers, and also
the tampons or wipers, with the means used to obtain a motion of the wipers,
similar to that of the human hand, substantially as herein-before described.
Fourth. The general arrangement and construction of the herein-before described
printing machine, with the various movements and actions, or any mere modifi-
cations of the same, substantially as herein-before described and shown.
In witness whereof, I, the said Edward Griffith Brewer, have hereunto set my
hand and seal, this Fifteenth day of February, in the year of our Lord
One thousand eight hundred and soventy-seven.
