Year: 1862

page_text: LETTERS PATENT to John Howard Kidd, of the City of Manchester, in
the County of Lancaster, Engineer, for the Invention of "AN IMPROVED
MANUFACTURE OF COMPOSITIONS APPLICABLE FOR WATERPROOFING FABRICA,
FOR COATING AND PROTECTING VARIOUS ARTICLES, AND FOR VARIOUS OTHER
PURPOSES."
Sealed the 25th November 1862, and dated the 28th May 1862.
PROVISIONAL SPECIFICATION left by the said John Howard Kidd at
the Office of the Commissioners of Patents, with his Petition, on the
28th May 1862.
I, JOHN HOWARD KIDD, of the City of Manchester, in the County of Lan-.
caster, Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED MANUFACTURE OF COMPOSITIONS APPLICABLE FOR WATERPROOPING FABRICS,
FOR COATING AND PROTECTING VARIOUS ARTICLES, AND FOR VARIOUS OTHER PURPOSES,"
to be as follows:-
According to my Invention, cod-fish or linseed oil, or both, are boiled with
oxide of lead, zinc, or other oxide, and then such prepared oil is exposed for
some time in thin films on extensive surfaces to the action of the air, and is
thus further oxydized and converted into a substance of semi-resinous nature;
this substance is then compounded with wax, mutton suet, and resin, in

page_text: about the following proportions:-Oxydized oil, forty parts; wax, two parts;
mutton suet, six parts; resin, thirty-two parts; and colouring matter as re-
quired. This composition is united and solved by heat, and is applied in the
hot or liquid state to the surface of the fabric or article to be coated or pro-
tected, or is moulded in that state into the required articles or forms. It is
not necessary for waterproofing fabrics or surfaces that any volatile solvent,
such as naptha, should be used in combination with the composition above
described, though it may be employed, and particularly in some cases when
used as a varnish.
My Invention further consists in combining india-rubber or gutta percha
with the composition above described, with or without the addition of volatile
solvents.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Howard Kidd in the Great. Seal Patent Office on
the 28th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOWARD KIDD, of the City of Manchester, in the County of Lancaster,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Howard Kidd, Her special license that I, the said John
Howard Kidd, my executors, administrators, and assigns, or such others as
I, the said John Howard Kidd, 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 COMPOSITIONS APPLICABLE FOR WATERPROOFING FABRICS,
FOR COATING AND PROTECTING VARIOUS ARTICLES, AND FOR VARIOUS OTHER PURPOSES,'
upon the condition (amongst others) that I, the said John. Howard Kidd, 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

page_text: 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 John Howard Kidd, do hereby declare
the nature of my 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) :-
.
According to my Invention, cod-fish or linseed oil, or both, are boiled with
oxide of lead, zine, or other oxide, and such prepared oil is exposed for some
time in thin films on extensive surfaces to the action of the air, and is thus
further oxydized and converted into a substance of semi-resinous nature; this
substance is termed oxydized oil. I take oxydized oil, obtained in the manner
described, or otherwise, and compound it with wax, mutton suet, and resins,
and these three substances I term the base of my compositions. The propor-
tions of each material forming the base, and the proportions of the base with
the oxydized oil, may be modified to a considerable extent according to the
purposes to which it is to be applied and the quality of the article desired.
Coloring matters are also added to the compositions to produce the effect
intended. For coating fabrics so as to waterproof them a suitable composition
is obtained by combining about forty parts of oxydized oil, two parts of wax,
six parts of mutton suet, and thirty-two parts of resins, and colouring matter
as required; but, as before stated, these proportions may be varied consider-
ably, and will have to be modified according to the result required. For
increased elasticity more oxydized oil may be used, and to make the composition
less liable to crack, more mutton suet or wax, or both mutton suet and wax
may be added, so that the best proportions will be readily obtained by trial
mixtures. The composition is united and solved by heat, and it is applied in
the hot, liquid, or plastic state to the surface of the fabric or articles to be coated
or protected, or it is moulded in that state into the required articles. It is not
necessary for waterproofing fabrics or surfaces that any volatile solvent, such
as naptha, should be used in combination with the composition above described,
though it may be employed, and particularly in some cases when used as a
varnish.
My Invention further consists in combining india-rubber or gutta percba
with the compound herein-before termed the base of my improved composition
5 namely, wax, mutton suet, and resins; and such compositions of my base and
india-rubber or gutta percha may be made either with or without volatile
solvents; the proportions in which they may be combined will vary according
to purpose required.

page_text: I have now particularly described and ascertained the nature of my Inven-
tion, and the mode of carrying the same into effect, and claim as my Invention,
for waterproofing fabrics, for coating and protecting various articles, and for
various other purposes,-
Firstly, a composition formed by the combination of oxydized oil and a base
formed of wax, mutton suet, and resins, and such colouring matters as may be,
required, as herein-before described.
Secondly, I claim a composition formed by a combination of india-rubber
or gutta percha with wax, mutton suet, and resins, as herein-before described.
In witness whereof, I, the said John Howard Kidd, have hereunto set.
my hand and seal, this Twenty-seventh day of November, in the year of.
our Lord One thousand eight hundred and sixty-two.
JOHN HOWARD KIDD. (L.S.)
