IMPROVEMENTS IN FLOOR CLOTH, AND IN ITS MANU- FACTURE
Year: 1864

page_text: LETTERS PATENT to John Howard Kidd and James Chadwick Mather,
both of the City of Manchester, in the County of Lancaster, for the
PROVISIONAL SPECIFICATION left by the said John Howard Kidd and
James Chadwick Mather at the Office of the Commissioners of Patents,
with their Petition, on the 23rd September 1864.
We, JOHN HOWARD KIDD and JAMES CHADWICK MATHER, both of the City
of Manchester, in the County of Lancaster, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN FLOOR CLOTH, AND IN ITS MANU-
FACTURE," to be as follows:-
The object of our Invention is the manufacture of an improved floor cloth
at reduced cost, resembling that known by the name of "kamptulican," and
our improvements consist in forming floor cloth by coating canvass or other
suitable woven fabric with a composition formed by taking about eight parts
by weight of the boiled linseed oil of commerce, or any other suitable drying
oil, and boiling it with about two parts by weight of resins till the compound
has attained the consistency of cement, mixing with the material so prepared
about eight parts by weight of fine ground cork, and then applying the com-
pound when properly combined to the face of the fabric, the back of the fabric
being coated with any suitable waterproofing material to protect it from..
damp.

page_text: The process and machinery or apparatus by which we carry out the manu-
facture of our improved floor cloth consists in boiling the oil and resins
together, then in placing the cement thus formed into a mixing machine
similar to that used for the manufacture of india-rubber, adding the ground
cork gradually while mixing; then in taking the caked material as it comes
from the "mixer," and breaking it up by means of a "bark" mill, from which
the disintegrated material is taken to a rolling mill and deposited upon an
endless cloth, to be carried along, over, and under heated surfaces, and
delivered thus heated to the heated rollers of the mill, which roll the material
upon the face of the fabric. The cloth thus prepared may be next taken to
a machine to receive a coating of waterproofing material upon its back, when
it is ready for the market as a plain cloth, or for ornamenting if required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Howard Kidd and James Chadwick Mather, in the
Great Seal Patent Office on the 21st March 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HOWARD KIDD and JAMES CHADWICK MATHER, both of the City of Manchester,
in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of September; in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said John Howard Kidd and James Chadwick Mather, Her
special license that we, the said John Howard Kidd and James Chadwick
Mather, our executors, administrators, and assigns, or such others as we, the
said John Howard Kidd and James Chadwick Mather, our executors, admi-
nistrators, 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 FLOOR CLOTH, AND IN ITS MANUFACTURE,"
upon the condition (amongst others) that we, the said John Howard Kidd and
James Chadwick Mather, by an instrument in writing under our hands and
seals (or under the hand and seal of one of us) 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

page_text: Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said John Howard Kidd and James
Chadwick Mather, do hereby declare the nature of our 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:-
The object of our Invention is the manufacture of an improved floor cloth
at reduced cost, resembling that known by the name of "kamptulicon." We
are aware that floor cloth has been manufactured already resembling "kamp-
tulicon," formed by a combination of material known as "oxidised oil" with
ground cork, such "oxidized oil" being obtained by exposing thin layers of oil
upon sheets to the atmosphere, by which the oil is entirely changed into a
material of new character.
We do not use oxidized oil in the manufacture of our improved floor cloth,
but our improvements consist in manufacturing floor cloth by coating canvass
or other suitable woven fabric with a composition formed by taking about
eight parts by weight of boiled linseed oil of commerce, or any other suitable
drying oil, and boiling it with about two parts by weight of resins till, the com-
pound has attained the consistency of cement, mixing with the material so
prepared about eight parts by weight of fine ground cork, sawdust, or like
materials, and sufficient pigments where color is required, and then applying
the compound when properly combined to the face of the fabric, the back
of which may be coated with any suitable waterproofing material to protect it
from damp.
The process and machinery or apparatus by which we carry out the manu-
facture of our improved floor cloth consists in boiling the oil and resins
together, then in placing the cement thus formed into a mixing machine
similar to that used for the manufacture of india-rubber or india-rubber
kamptúlicon, adding the ground cork or other like material. gradually while
mixing, and pigments where color is required, then in taking the caked material
as it comes from the mixer, and breaking it up by means of a bark or other
suitable mill, from which the disintegrated material is removed to a rolling mill,
and deposited upon an endless cloth, to be carried along, over, and under
heated surfaces, and delivered thus heated to the heated rollers of the mill, to
be rolled upon the face of the fabric. The cloth thus prepared may be next
taken to a machine to receive a coating of waterproofing material upon its back,
when it is ready for the market, or for ornamenting if required. The material
as it comes from the mixing machine may be rolled into sheets of the required

page_text: thickness, and these sheets of material when sufficiently heated may be rolled
upon the face of the fabric by the rolling mill.
We have now particularly described the nature of our Invention, and the
manner of carrying the same into effect, and wish it to be understood that we
claim the improved floor cloth obtained by coating a woven fabric with a
composition formed of the boiled linseed oil of commerce or any other drying
oil treated in the manner herein-before explained and mixed with ground cork,
sawdust, and other like materials, and with pigments where color is required,
and also the application of the process and machinery- herein-before described
when used for manufacturing our improved floor cloth.
In witness whereof, we, the said John Howard-Kidd and James Chadwick
Mather, have hereunto set our hands and seals, this Twentieth day
of March, in the year of our Lord One thousand eight hundred and
sixty-five.

JAMES CHADWICK MATHER. (L.s)
