AN IMPROVED MANUFACTURE OF INKING ROLLERS
Year: 1865

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "AN IMPROVED MANUFACTURE OF INKING
ROLLERS." A communication from abroad by Lewis Francis and Cyrus
Loutrel, of the City of New York, United States of America.
Sealed the 25th July 1865, and dated the 31st March 1865.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton at
the Office of the Commissioners of Patents, with his Petition, on the
31st March 1865.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare
the nature of the said Invention for "AN IMPROVED MANUFACTURE OF INKING
ROLLERS," to be as follows:-
The object of this Invention is to produce inking, rollers that will not be
effected by changes of temperature, but at all times be fit for use. To this
end the rollers instead of being made as heretofore of glue and treacle, which
require washing two or three times a day, are composed by preference of glue,
glycerine, sugar, or any other saccharine matter, soap, or alkalies or alkaline
earths, or any of the compounds of alkalies or alkaline earths and castor oil,
or any of the fixed oils or the sugar, or the soap, or the oil, or their equivalents
may be omitted from the composition.

page_text: The following proportions of the materials used may be given as an example,
glue, 25 pounds; glycerine, 50 pounds; white sugar, 18 pounds; soap, 1
pound; castor oil, 3½ pounds.
The glue is first soaked in water for about five or ten minutes, the water is
then decanted, and the glue is left to soften; after which it is placed in a steam
or glue kettle and heated, and the other ingredients are then added. The
mixture having been subjected for about forty minutes. to a. temperature of
about 200° Fahrenheit is ready for casting to the required form. It will be
found that rollers made from this composition will not require washing for
twenty or thirty days, as they do not lose their life or suction, and do not
attract and hold dust, dirt, or foreign substances.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed.
by the said Alfred Vincent Newton in the Great Seal Patent Office on
the 30th September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of March, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Alfred Vincent Newton, Her special licence that I, the said
Alfred Vincent Newton, my, executors, administrators, and assigns, or such
others as I, the said Alfred Vincent Newton, 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 MANUFACTURE OF INKING ROLLERS," being a communication from
Lewis Francis and Cyrus Loutrel, of the City of New York, United
States of America, upon the condition (amongst others) that I," the said Alfred
Vincent Newton, 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.
'

page_text: NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
:-
It is well known to all printers how difficult a matter it is to keep inking
rollers in a proper condition for use for more than three months; particularly
those made of treacle and glue, while those consisting of glue and glycerine
have totally failed for want of possessing a proper affinity for printing.inks.
Now the object of this Invention is to produce inking rollers that will. not
To
be affected by changes of temperature, but will at all times be fit for use."
this end the rollers instead of being made as heretofore of glue and treacle
which require washing two or three times a day are composed by preference of
glue, glycerine, sugar, or other saccharine matter, soap, or alkalies, or alkaline
earths, or any of the compounds of alkalies or alkaline earths, and castor oil,
or any of the fixed oils. In some cases the sugar, or the soap, or the oil, or
their equivalents, may be omitted from the composition.
The following proportions of the materials used may be given as an example,
glue, twenty-five pounds; glycerine, fifty pounds; white sugar, eighteen
pounds; soap, one pound; castor oil, three and a half pounds.
The glue is first soaked in water for about five or ten minutes. The water
is then decanted, and the glue is left to soften, after which it is placed in a
steam or glue kettle, and heated, and the other ingredients are then added.
The mixture having been subjected for about forty minutes to a temperature
ranging near two hundred degrees Fahrenheit is ready for casting to the
required form, or it may be cast into blocks or sheets, and set aside for future
use. It will be found that rollers made from this composition will not require
washing for twenty or thirty days, as they do not lose their "life" or "suction,"
and do not attract and hold dust, dirt, or foreign substances, whereas other
rollers require washing always at the end of each day's work, as otherwise the
ink will dry and harden on the face of the roller, rendering the same unfit for
use, ink will not however dry on a roller made of this composition under four
or five days.
Supposing the composition to be in blocks or sheets, and that it is required
to convert it into inking rollers, the operator must see that his heating kettle
is clean, and he must put the composition into the kettle, gradually stirring as
it is put in, when melted it should be allowed to stand for about twenty minutes
without stirring to allow any air which it may contain to escape. By so doing
air holes will be avoided in the casting. Having seen to the oiling of the
moulds, the workman must pour a gentle stream on the end of the stock from

page_text: a convenient sized kettle with a proper shaped lip. This operation must be
done neatly, or air holes will be produced. If the composition should be found
too thick to pour into some small moulds, a little water may be added. When
water is added, the rollers cast from the fluid composition will require to stand
a few days longer before being used to allow it to evaporate, but in all cases
it will be best to let the rollers stand a few days after casting before using
them, although they may, if necessity require it, be used immediately. The
shrinkage of the rollers in cooling will be proportionate to the amount of water
evaporated. When casting in the morning the rollers may be drawn in the
evening, unless they are of large size, for they never draw well from moulds
that are very cold. If convenient the moulds should stand in a warm place
in order to acquire the temperature of blood heat when drawn.
Having. now set forth the nature of the Invention of "An Improved
Manufacture of Inking Rollers," and explained the manner of carrying the
same into effect, I wish it to be understood that I do not confine myself to
the combined use of all the materials above mentioned, or their equivalents, as
the sugar, or the soap, or the oil may be omitted without materially affecting
the desired result, and the proportions may also be slightly varied.
I claim under the above in part recited Letters Patent, manufacturing
inking rollers in the manner above described.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto set
my hand and seal, the Thirtieth day of September, in the year of
our Lord One thousand eight hundred and sixty-five.
A. V. NEWTON. (L.S.)
