PROVISIONAL SPECIFICATION left by the said Stephen Moulton
at the Office of the Commissioners of Patents, with his Petition,
on the 9th May 1868.
I, STEPHEN MOULTON, of Bradford, in the County of Wilts, India
rubber Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE TREATMENT OF VULCANIZED OR CURED INDIA-RUBBER
FOR OBTAINING A SUBSTANCE OF A MOSSY NATURE SUITABLE FOR PRINTERS
INKING ROLLERS, CUSHIONS, AND OTHER ARTICLES," to be as follows:-
The object of my Invention is to obtain a substance of a mossy
nature suitable for forming the body of printers' inking rollers, cushions,
and other articles.

page_text: I treat vulcanized or cured india-rubber as follows:-I grind or
reduce it to powder; I then put it into moulds of any desired form,
and subject it to a second curing or vulcanizing heat as com-
monly used by rubber manufacturers. This second heating forms the
rubber into a homogeneous mossy substance suitable for the purposes
aforesaid.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Stephen Moulton in the Great Seal Patent Office
on the 26th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHEN
MOULTON, of Bradford, in the County of Wilts, India-rubber Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of May, in the year
of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Stephen Moulton, Her special
licence that I, the said Stephen Moulton, my executors, adminis-
trators, and assigns, or such others as I, the said Stephen Moulton,
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
"IMPROVEMENTS IN THE TREATMENT OF VULCANIZED OR CURED INDIA-RUBBER
FOR OBTAINING A SUBSTANCE OF A MOSSY NATURE SUITABLE FOR PRINTERS'
INKING ROLLERS, CUSHIONS, AND OTHER ARTICLES," upon the condition
(amongst others) that I, the said Stephen Moulton, 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

page_text: NOW KNOW YE, that I, the said Stephen Moulton, do hereby declare
the nature of my 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 improvements in the treatment of
vulcanized or cured india-rubber for the purpose of obtaining a
substance of a mossy nature suitable for forming the body of printers'
inking rollers, cushions, and other articles.
The mode or manner in which the same is effected is as follows:-
I take the well-known article vulcanized or cured india-rubber, with
or without its containing any foreign admixture except sulphur, and
grind or reduce it to powder or dust; I then subject it to a second
vulcanizing heat, the powder or dust being placed (previous to this
second vulcanizing) in a suitable mould according to the particular
form or shape of the article required. If the article to be moulded be,
say, a printer's inking roller, I put the powder or dust into a suitable
hollow cylinder with the iron spindle for the centre of the roller
therein; when the powder or dust has become converted by the
vulcanizing heat into a homogeneous mossy substance I cover it with
a skin of rubber and sulphur with or without other compounds, and
then again subject the whole to a vulcanizing heat in order to vulcanize.
or cure the rubber skin. The roller is then ready for use. For some
purposes the moss rubber may be covered on one or both sides with
sheet rubber, cotton cloth, or other suitable fabric, or it may be
left uncovered according to the article to which it is to be applied.
And having now described the nature of my said Invention, and
in what manner the same is to be performed, I declare that I
claim, treating vulcanized or cured india-rubber substantially in the
manner herein-before described in order to obtain a substance of a
mossy nature suitable for the purposes aforesaid.
In witness whereof, I, the said Stephen Moulton, have hereunto
set my hand and seal, this Twenty-second day of October, One
thousand eight hundred and sixty-eight.
STEPN. MOULTON. (L.S.)
