the Invention of " IMPROVEMENTS IN THE PREPARATION AND TREATMENT OF
PROVISIONAL SPECIFICATION left by the said Edward Charles Vickers
at the Office of the Commissioners of Patents, with his Petition,
on the 25th March 1873.
I, EDWARD CHARLES VIOKERS, of Compton Street, Clerkenwell, in
5. the County of Middlesex, Hat Manufacturer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE PREPARATION AND
TREATMENT OF PAPER TO BE USED AS A SUBSTITUTE FOR LEATHER," to be as
follows:-
For the purposes of this Invention hand made paper is employed in
O the manufacture of which, if the same is desired to possess an uniform

page_text: colour throughout its substance, suitable colouring matters are mixed
with the pulp. If however it is not necessary for the paper to possess
such uniform colour throughout its substance, the same may be super-
ficially coloured after manufacture, as well understood, or may be used in
an uncoloured state. By preference paper manufactured without the t
addition of size or other stiffening material such as is generally used is
employed for the purposes of this Invention. One side of the paper,
that is to say, the side which is to be the front or that exposed to view,
is oiled, or painted, or enamelled, or japanned, or simply coated with tan
liquor. The back or other side of the paper is then coated with 1
glycerine. The sheets so prepared and treated being finally dried by
exposure to the atmosphere. Paper thus prepared and treated is capable
of being used for many purposes as a substitute for leather, and is
possessed of great pliability and softness.

filed by the said Edward Charles Vickers in the Great Seal Patent
Office on the 24th September 1873.

the said Edward Charles Vickers, 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

NOW KNOW YE, that I, the said Edward Charles Vickers, 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, that is to say :-
For the purposes of my said Invention, paper either formed of
vegetable or animal pulp, or of a mixture thereof, is employed in the
manufacture of which, if the same is desired to possess an uniform
colour throughout its substance, suitable colouring matters are mixed
with the pulp. If however it is not considered necessary for the paper
to possess such uniform colour throughout its substance, the same may
be superficially coloured after manufacture, as well understood, or may
be used in an uncoloured state. One side of the paper, that is to say,
the side which is to be the front or that exposed to view, is glazed, or
oiled, or painted, or enamelled, or japanned, or varnished, or simply
coated with tan liquor. The other side of the paper is then coated with
glycerine (that substance being used by preference although other oily
substances may be employed), and the sheets so prepared are then
finally dried by any suitable means. The paper so prepared may if
desired be combined with any suitable textile fabric by any of the well
known means.
Paper prepared and treated in the manner above described, is possessed
of great pliability and softness, and is capable of being advantageously
used for many purposes as a substitute for leather.
Having thus declared and ascertained the nature of my said Invention,
and the manner in which it is to be performed, I would observe in con-
clusion that what I consider novel and original and therefore claim as
constituting the Invention secured to me by the said herein-before in
part recited Letters Patent, is, the preparation and treatment of naner.

page_text: substantially as and for the purposes herein-before described and set
forth.
In witness whereof, I, the said Edward Charles Vickers, have here-
unto set my hand and seal, this Twenty-second day of September,
in the year of our Lord One thousand eight hundred and
seventy-three.
