Year: 1857

page_text: LETTERS PATENT to Anthony Lorimier, of Bedford Square, East Com-
mercial Road, in the County of Middlesex, for the Invention of "AN
IMPROVEMENT IN PREPARING THE SURFACES OF PRINTERS INKING ROLLERS AND
OTHER ARTICLES WHEN VULCANIZED INDIA-RUBBER IS USED."
Sealed the 23rd June 1857, and dated the 1st January 1857.
PROVISIONAL SPECIFICATION left by the said Anthony Lorimier at the
Office of the Commissioners of Patents, with his Petition, on the
1st January 1857.
I, ANTHONY LORIMIER, of Bedford Square, East Commercial Road, in the
County of Middlesex, do hereby declare the nature of the Invention for
"AN IMPROVEMENT IN PREPARING THE SURFACES OF PRINTERS INKING ROLLERS AND
OTHER ARTICLES WHEN VULCANIZED INDIA-RUBBER IS USED," to be as follows:-
This Invention has for its object an improvement in preparing the surfaces
of printers' inking rollers and other articles when vulcanized india-rubber is
used, and consists of subjecting the surfaces to heat, so as partially to melt
the same, and thereby to improve such surfaces. The most convenient mode
is by causing heated iron or other metal to pass over such surfaces.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANTHONY
LORIMIER, of Bedford Square, East Commercial Road, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, hearing date the First day of January, in the year of our Lord
One thousand eight. hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself. Her heirs and successors, give and grant unto me, the said
Anthony Lorinier. Her special licence that. I. the said Anthony Lorimier, my
executors, administrators, and assigns, or such others as 1. The said Anthony
Lorimier, 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 luvention for AN IMPROVEMENT IN
PREPARING THE SURFACES OF PRINTERS INKING ROLLERS AND OTHER ARTICLES WHEN
VULCANIZED INDIA-RUBBER IS USED," upon the condition (amongst others) that I,
the said Anthony Lorimier, my executors or administrators. by an instrument
in writing under my. or their, or one of their hands and seals, should par-
ticularly 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 Anthony Lorimier. do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say :-
This Invention has for its object an improvement in preparing the surfaces
of printers inking rollers and other articles when vulcanized india-rubber is
used, and consists of subjecting the surfaces to heat, so as partially to melt
the same, and thereby to improve such surfaces. The most convenient mode
is by causing heated iron or other metal to pass over such surfaces.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe more fully the method in
which I prefer to conduct the process.
For manufacturing a printer's roller for distributing ink on a table, I select

page_text: a stout and flexible vulcanized india-rubber tube. as soft as may be obtained
and of suitable size and length, and I draw it on to the stock of the roller:
then I take a metal rim of such a size as to allow of the roller just to pass
through it; heat this ring to a blood-red heat, and pass the roller steadily
through it several times, so as to move all irregularities in the surface, and
also partly to melt it; lastly, I coat the surface of the roller with dissolved
vulcanized india-rubber, which I prepare by crushing scraps of that material
between rollers, and afterwards heating it in contact with the vapour of a solvent,
as is described in the Specification of a former Patent granted to me, and
dated October the 20th, 1856. When the roller is dry it is ready for use.
In order to prepare a roller to be used to apply ink to the surface of type,
I prefer to mould it from scraps of vulcanized india-rubber, according to the
process described in the Specification above referred to. I take scraps of
vulcanized india-rubber, and I pass them, together with a little india-rubber
solvent, between crushing rollers, until they are reduced to a granulated state;
with this I mix an equal quantity of dissolved vulcanized india-rubber, pre-
pared in the way already described, and in a semi-fluid state 1 pass the mixture
again between the crushing rollers, and then fill it into a metal mould con-
taining the stock or core previously coated with the dissolved india-rubber.
When the mould is well filled I screw up the two ends of the mould, so as to
subject the material to considerable pressure, and I then submit it for about
three hours to the temperature of boiling water, either by immersing it in
boiling water or otherwise. After the moulded roller comes from the mould
its surface is finished by passing through a heated ring and coating it with
dissolved vulcanized india-rubber, in the way already described in reference to
rollers made from tubes. I also prepare printers balls or dabbers in methods
similar to those which I have just described for preparing rollers.
In witness whereof, 1. the said Anthony Lorimier, have hereunto set my
hand and seal, this Thirtieth day of June, in the year of our Lord
One thousand eight hundred and fifty-seven.
Witness.
