in the County of Lancaster, Chemist, for the Invention of "A
METHOD OF UTILISING THE CARDS WHICH HAVE BEEN USED IN THE CARDING
OF TEXTILE MATERIALS, OR OF OBTAINING USEFUL SUBSTANCES AND MATERIALS
"
PROVISIONAL SPECIFICATION left by the said Joseph Lambert
de Montoison at the Office of the Commissioners of Patents, with
his Petition, on the 9th June 1875.
I, JOSEPH LAMBERT DE MONTOISON, of Manchester, in the County of
Lancaster, Chemist, do hereby declare the nature of the said Invention
for "A METHOD OF UTILISING THE CARDS WHICH HAVE BEEN USED IN THE CARDING
OF TEXTILE MATERIALS, OR OF OBTAINING USEFUL SUBSTANCES AND MATERIALS
THEREPROM," to be as follows:-
My Invention relates to the cards which have been employed in the
carding of textile materials, and have been discarded from use in

page_text: consequence of wear and deterioration, and has for its object to obtain
the materials of which such cards are composed, or some of the materials,
in such forms as to be available to be again employed for useful
purposes. I take the said cards, say for example, cards which have
been in use on the flats, rollers, or cylinders of carding engines, and I
immerse them in an acid bath until the iron or steel dents are entirely
dissolved, and I thus obtain salts of iron or iron liquor, or both salts and
liquor. The foundation of the cards is removed from the bath, and in
most cases furnishes useful materials.
In some cases the said foundation consists of cloth united with
cement, or of sheets of caoutchouc backed with cloth. In such cases
the cloth may be separated, and be used in the making of paper, or
may be found useful for other purposes; and in the latter case the
sheets or fillets of caoutchouc may be separated from the cloth, and be
available for remanufacture.
By way of example, I may state that a mixture I now consider to be
suitable may be made by adding to water about forty per cent. of
sulphuric acid, about ten per cent of hydrochloric acid, and about five
per cent. of acetic acid or sour beer, or other liquid containing acetic
acid may be substituted wholly or in part for the water, or I may add
a small proportion of yeast to the acid bath.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Lambert de Montoison in the Great Seal
Patent Office on the 9th December 1875.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH 2
LAMBERT DE MONTOISON of Manchester, in the County of Lancaster,
Chemist, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of June, in the year of
our Lord One thousand eight hundred and seventy-five, in the fortieth 3
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Joseph Lambert de Montoison, Her special
licence that I, the said Joseph Lambert de Montoison, my executors,

page_text: ·
administrators, and assigns, or such others as I, the said Joseph Lambert
de Montoison, my exccutors, 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 "A METHOD OF UTILISING THE CARDS WHICH HAVE BEEN USED IN THE CARDING
OF TEXTILE MATERIALS, OR OF OBTAINING USEFUL SUBSTANCES AND MATERIALS
THEREFROM," upon the condition (amongst others) that I, the said Joseph
Lambert de Montoison, 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 immediately after the date of the said Letters

page_text: or fillets of caoutchouc may be separated from the cloth, and be
available for remanufacture.
In other cases the said foundation consists of leather, which is
recovered after the dissolution of the dents, and may be used in the
making of boots and shoes, or for any other purposes for which it may
be found to be suitable.
By way of example, I may state that a mixture, I now consider to be
suitable, may be made by adding to water about forty per cent. of
sulphuric acid of a strength of about sixty-six to seventy degrees, about
ten per cent. of hydrochloric acid and about five per cent. of acetic acid
or sour beer, or other liquid containing acetic acid may be substituted
wholly or in part for the water, or I may add a small proportion of
yeast to the acid bath.
In some cases 'the same bath may be employed to act upon successive
charges of cards, the strength being restored after each operation by the
addition of acids. If it be desired to produce iron liquor or sulpho-
acetate of iron, I may increase the quantity of acetic acid and reduce the
quantity of sulphuric acid, and I may add the hydrochloric acid after
the solution of the iron has been effected, in order to neutralise to some
extent the sulphuric acid. I thus obtain sulpho-acetate of iron liquor
suitable to be employed in the dyeing of wool, cotton, silk, and other
materials. During the operation of dissolving the dents of the cards
hydrogen gas is evolved, and if the solution be effected in a closed
vessel, the said gas may be collected and be used for heating, lighting,
or other
purposes.
When the indicated mixture of acids is employed, sulpho-acetate of
iron useful for dyeing purposes, and for the preparation of acetate of
protoxide, and peroxide of iron, and other acetates may be obtained
from the liquor in which the cards have been treated, but I do not
confine myself to the use of such mixture..
Having now fully set forth and indicated the nature of my said
Invention, and means whereby the same may be carried into effect, I
remark in conclusion that I claim,―
First. The treatment of such cards as herein indicated with acid
liquids or liquors in order to obtain useful products or matters.

page_text: Secondly. The treatment of the said cards, with the mixtures of acids
and liquids, or matters substantially as and for the purposes herein-
before set forth and indicated.
And, lastly. The method of producing iron liquor substantially as
herein-before set forth and indicated.
In witness whereof, I, the said Joseph Lambert de Montoison,
have hereunto set my hand and seal, this Eighth day of
December, in the year of our Lord One thousand eight hundred
and seventy-five.
