PROVISIONAL SPECIFICATION left by the said Frederick Ayck-
bourn at the Office of the Commissioners of Patents, with his
Petition, on the 22nd June 1853.
I, FREDERICK AYCKBOURN, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF WATERPROOF
FABRICS" to be as follows:-
My Invention consists in rendering waterproof woven, felted, looped,
and other similar fabrics and paper, and also leather, by coating, cover-
ing, or preparing the same with a solution or preparation of india-
rubber, or with chouca, marine glue, or other suitable cement, and
then facing the surface of such coating, covering, or preparation with
gutta-percha in a thin sheet or layer, or in several thin sheets or layers,

page_text: by means of cylinders or by a table, or by a table and a cylinder
or cylinders combined, or by pressure or other equivalent and suitable
means, or by facing the surface of such coating, covering, or prepara-
tion with gutta-percha in the form of a paste, or in solution, or in a
plastic state, by means of a spreader or brush, or by a cylinder, or by
pressure or other equivalent and suitable means.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Ayckbourn in the Great Seal Patent
Oflice, on the 21st December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
FREDERICK AYCKBOURN, of 99, Guildford Street, Russell Square, in the
County of Middlesex, Patent Folding Boat Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of June, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Frederick Ayckbourn, Her
special licence that I, the said Frederick Ayckbourn, my executors,
administrators, and assigns, or such others as I, the said Frederick
Ayckbourn, 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 MANUFACTURE OF WATERPROOF
FABRICS," upon the condition (amongst others) that I, the said Frederick
Ayckbourn, by an instrument in writing under my hand and seal, 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 Frederick Ayckbourn, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):
My Invention consists in rendering waterproof woven, felted, looped,
and other similar fabrics and paper, and also leather, by coating, cover-
ing, or preparing the same with a solution or preparation of indian
rubber, or with chouca, marine gluc, or other suitable cement, and
then facing the surface of such coating, covering, or preparation with
gutta-percha in the form of a paste, or in solution, or in a plastic
state.
And having thus set forth the nature of my said Invention, I will
now proceed to describe the manner in which it is to be performed
according to the process or processes which I prefer, and by which I
consider it may be best carried into effect.
I take a piece of woven, felted, or looped cloth or other fabric, or a
piece of paper or leather, and coat or cover the same in the manner
described in the Specification of a Patent granted to me, and bearing
date the Twenty-second day of December, One thousand eight hundred
and fifty-two, or by any other ordinary well-known processes, with
india-rubber solution, or with chouca, marine glue, or other cement, in
suitable quantity or proportion, according to the nature of the fabric em-
ployed, and in one or more coats or separate applications, according to
the nature and purpose of the material to be proofed. Between each
coat or application I drive off by heat, or allow to evaporate by expo-
sure to the air, the volatile spirit contained in the solution or cement
in the ordinary manner, and I then face the surface of the coating,
covering, or preparation so firstly formed or applied (in one or more
layers) by or with the gutta-percha (in the form of a paste or solution,
or in a plastic state), and heated to the requisite temperature for freely
working the same (such paste or solution being also applied in one or
more layers) by the ordinary process or processes, or any of them, as I
have already described for the said firstly formed or applied coating,
covering, or preparation, and thus I form or apply a second coating,
covering, or preparation in one or more layers outside of and upon the
surface of the first.

page_text: Both sides of the fabric or material may be similarly treated, in
which case I complete the process or processes on one side first, and
afterwards those on the other.
I wish it to be understood that I herein lay no claim to the applica-
tion of gutta-percha in sheets to or upon surfaces prepared as herein
described, as such application is already the subject of the Letters
Patent granted me, which are herein-before referred to.
In witness whereof, I, the said Frederick Ayckbourn, have here-
unto set my hand and seal, this Twenty-first day of December,
in the year of our Lord One thousand eight hundred and fifty-
three.
FREDERICK AYCKBOURN. (L.S.)
