IMPROVEMENTS APPLICABLE TO PRINTING MANUTUNDY
Year: 1872

page_text: LETTERS PATENT to James Cope, of New North Street, Finsbury, in
the County of Middlesex, Printing Machine Manufacturer, and
Edmund Charles Barrett, of Montague Road, in the same County,
Printer, for the Invention of "IMPROVEMENTS APPLICABLE TO PRINTING
MANUTUNDY "
Sealed the 10th October 1872, and dated the 31st May 1872.
PROVISIONAL SPECIFICATION left by the said James Cope and
Edmund Charles Barrett at the Office of the Commissioners of
Patents, with their Petition, on the 31st May 1872.
We, JAMES COPE, of New North Street, Finsbury, in the County of
Middlesex, Printing Machine Manufacturer, and EDMUND CHARLES
BARRETT, of Montague Road, in the same County, Printer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS APPLICABLE
TO PRINTING MACHINERY," to be as follows:-
Our Invention of improvements applicable to printing machinery
relates to the inking apparatus used in printing machines, and has for its
object to obviate the necessity of cutting or reducing the surface of the

page_text: vibrating roller, as is now commonly practised, to prevent this roller at
certain parts from taking up ink from the ductor roller.
The Invention consists in adapting to the under side of the ductor
roller spring bands made of thin steel or other suitable substance, which
are suspended from clips in an adjustable frame adapted to the front of
the roller. These spring bands are capable of being adjusted laterally
along the frame, their position being regulated by the size and nature of
the form of type to be operated upon. The spring bands may be of any
convenient length, so as to extend beyond the back of the ductor roller,
and their width should correspond to the spaces between the pages of
type in the form. In their normal position the spring bands will project
under the ductor roller, and about one quarter of an inch therefrom;
but when the vibrating is raised up in contact with the ductor roller
for the purpose of taking a supply of ink therefrom, the vibrating roller
will press the spring band between it and the ductor roller, and a portion
of the surface of the latter will thus be covered up and prevented from
transferring any ink to that part of the vibrating roller which is imme-
diately underneath. From this it will be seen that only that portion of
the distributing table and inking rollers which correspond with the
positions of the type will be supplied with ink. The necessity for
cutting away a portion of the vibrating roller to effect the same object is
therefore obviated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Cope and Edmund Charles Barrett in the
Great Seal Patent Office on the 30th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
COPE, of New North Street, Finsbury, in the County of Middlesex,
Printing Machine Manufacturer, and EDMUND CHARLES BARRETT, of
Montague Road, in the same County, Printer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her:
Letters Patent, bearing date the Thirty-first day of May, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said James Cope and Edmund Charles

page_text: Barrett, Her special licence that we, the said James Cope and Edmund
Charles Barrett, our executors, administrators, and assigns, or such
others as we, the said James Cope and Edmund Charles Barrett, our
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 "IMPROVEMENTS
APPLICABLE TO PRINTING MACHINERY," upon the condition (amongst others)
that we, the said James Cope and Edmund Charles Barrett, our exe-
cutors or administrators, by an instrument in writing under our, 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 Edmund Charles Barrett, on behalf
of myself and of the said James Cope, do hereby declare the nature of
our said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereunto annexed, and
to the letters and figures marked thereon (that is to say):
:-

Our Invention of "Improvements applicable to Printing Machinery
relates to the inking apparatus used in printing machines, and has for its
object to obviate the necessity of cutting or reducing the surface of the
vibrating roller, as is now commonly practised, to prevent this roller at
certain parts from taking up ink from the ductor roller.
In the accompanying Drawing we have shewn various views of the
arrangement of parts whereby the object of our Invention may be
effected.
Fig. 1 is a front view of our improved apparatus adapted to the ink
fountain and ductor roller of a printing machine; Fig. 2 is a transverse
vertical section of the same.
The Invention consists in adapting to the under side of the ductor
roller a spring bands b, b. These bands 6, 6, are made of thin steel or
other suitable substance, and they are suspended from the bars d², d¹, of
the frame, and are held by clips formed by the bars c, c, and the bars d'

page_text: b
of the moveable frame d. The bars c and d are nipped together by the
screw clips c, c¹, which are made moveable along the bars c and d³, so as
to allow of the steel bands being placed in any position. The spring
bands 6 are thus capable of being adjusted laterally by sliding or moving
them along the frame d, their position being regulated by the size and
nature of the form of type to be operated upon. The spring bands 6 may
be of any convenient length, so as to extend beyond the back of the
ductor roller a, and their width should correspond to the spaces between
the pages of type in the form. In their normal position the spring
bands will project under the ductor roller a, and about one quarter of an
inch therefrom; but when the vibrating roller e is raised up in contact
with the ductor roller a for the purpose of taking a supply of ink there-
from, the vibrating roller e will press the spring bands 6 between it and
the ductor roller a, and a portion of the surface of the latter will thus be
covered up and prevented from transferring any ink to that part of the
vibrating roller e which is immediately underneath. It will be seen
that the frames d are mounted on centres at d*, and are supported in the
side standards f, f. The frames d are therefore capable of vibrating or
turning on these centres, so that when the bands b, b, are nipped between
the rollers a and e they will be drawn forward and the frame d will be
vibrated on its centres until the roller e drops and releases the steel
bands b, b; the weight of the frame d will then bring it back into its
normal position, as shewn in the Drawings. It will now be understood
that only that portion of the distributing table and inking rollers which
correspond with the positions of the type will be supplied with ink. The
necessity for cutting away a portion of the vibrating roller e to effect the
same object is therefore obviated.
It will sometimes be required to lessen the quantity of ink to be
supplied to some parts of the distributing table or inking rollers, but not
to entirely cut it off, as will be the case when bands such as those
shewn at b, b, are used to cover up entirely some of the parts.
When a reduced and modified quantity is required, this is effected by
employing perforated bands, as at Fig. 4. The ink will only be supplied
to the vibrating roller at those parts where the metal band is perforated.
Having now described our Invention, and having explained the
manner of carrying the same into effect, we claim as the Invention
secured to us by Letters Patent as aforesaid, adapting to the vibrating

page_text: and ductor rollers of the inking apparatus of printing machines bands or
strips of steel or other suitable substance, as herein set forth, for the
purpose of preventing the vibrating roller e from taking ink from the
ductor roller at those parts where it is not required.
In witness whereof, I, the said Edmund Charles Barrett, have
hereunto set my hand and seal, the Twenty-eighth day of
November, in the year of our Lord One thousand eight hundred
and seventy-two.
E. C. BARRETT. (L.S.)
