IMPROVEMENTS IN FLOORCLOTH AND IN MACHINERY FOR THE MANUFACTURE OF FLOORCLOTH
Year: 1865

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
Invention of "IMPROVEMENTS IN FLOORCLOTH AND IN MACHINERY FOR THE
MANUFACTURE OF FLOORCLOTH."
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 18th March 1865.
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 FLOORCLOTH AND IN MACHINERY FOR
THE MANUFACTURE OF FLOORCLOTH." to be as follows:-
Our improvements in floor cloth are made upon those for which Letters
Patent were granted to us, No. 2340. and dated the Twenty-third day of
September, in the year of our Lord One thousand eight hundred and sixty-four,
and the object of which was the manufacture of an improved floorcloth at
reduced cost, resembling that known by the name of "kamptulicon."
The composition described in the Specification of the said Letters Patent is
formed by taking the boiled linseed oil of commerce, or any other suitable
drying oil, and in boiling it with resins until it has attained the consistency of
cement.
Our present, improvements (by which the composition is rendered more
elastic) consists in taking the boiled linseed oil of commerce, or any other suitable
drying oil, and boiling it alone until it has attained the consistency of cement,
[Price 8d.]

page_text: when it is mixed with ground cork, sawdust, or other like materials, and when
properly combined it is applied to the surface of the fabric as described in the
Specification herein-before referred to.
Our improvements in floorcloth also consist in taking a composition similar
to that above described, or that described in the Specification of our said
Patent, or a composition formed partly as described and partly of suitable
seeds of drying oil, ground fine, and applying it to the back of a woven fabric
by a rolling mill, coating the face side of such fabric with waterproofing material
by a spreading or rolling machine, then pumicestoning, and priming, and
ornamenting it, if required.
Our improvements in machinery for the manufacture of floorcloth according
to our improvements, or any other floorcloth formed by a mixture of adhesive
material with cork and like material, or formed of adhesive material and
pigments, relates to the mills used for rolling the material upon the surface of
the fabric, which have been hitherto formed of a single pair of rollers. The
pressure required in such mills is so great that the rollers spring or give way
to the material to be rolled upon the fabric, which is consequently thicker at the
middle than at the edges of the fabric, and this fault increases with the width
of the fabric to be operated upon, as a corresponding increase in the diameter
of the rolls to give increased strength is found to be a disadvantage.
Our improvements consist in making the rollers which come in contact with
the fabric of the most convenient diameter, and in adding one or more rollers
to work against each roller in contact with the fabric, so as to sustain and
resist the pressure coming thereon. The two rollers in contact with the
fabric may be rotated by shafts so coupled as to admit of movement to a
small extent in the rollers to and from each other, and these shafts may be
driven by gearing in the same manner as mills for rolling iron. The sup-
porting rollers may be geared with the rollers in contact with the fabric.
The rollers are made hollow and heated by steam or other suitable means, and
are provided with suitable doctors or scrapers to remove any adhering matter.
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 18th September 1865.

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 ex-
ecutors, 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 FLOOR CLOTH AND
IN MACHINERY FOR THE MANUFACTURE OF FLOORCLOTH," 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 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 and accompanying Drawings,
that is to say :-
Our improvements in floorcloth are made upon those for which Letters
Patent were granted to us, Number 2340, and dated the Twenty-third day of
September, in the year of our Lord One thousand eight hundred and sixty-
four, and the object of which was the manufacture of an improved floorcloth
at reduced cost, resembling that known by the name of "kamptulicon."
The composition described in the Specification of the said Letters Patent is
formed by taking the boiled linseed oil of commerce, or any other suitable
drying oil, and in boiling it with resins until it has attained the consistency of
cement.
Our present improvements (by which the composition is rendered more
elastic) consists in taking the boiled linseed oil of commerce, or any other
suitable drying oil, and boiling it alone until it has attained the consistency of
cement, when it is mixed with ground cork, sawdust, or other like materials,

page_text: and when properly combined it is applied to the surface of the fabric as
described in the Specification herein-before referred to.
Our improvements in floorcloth also consist in taking a composition similar
to that above described, or that described in the Specification of our said
Patent, or a composition formed partly as described and partly of suitable
seeds, of drying oil, ground fine, and applying it to the back of a woven fabric
by a rolling mill, coating the face side of such fabric with any suitable and
well known waterproofing material by a spreading or rolling machine, then
pumicestoning, and printing, and ornamenting it, if required.
Our improvements in machinery for the manufacture of floorcloth according
to our Invention, or any other floorcloth formed by a mixture of adhesive
material with cork and like material, or form of adhesive material and
pigments, relates to the mills used for rolling the material upon the surface of
the fabric, which have been hitherto formed of a single pair of rollers. The
pressure required in such mills is so great that the rollers spring or give way
to the material to be rolled upon the fabric, which is consequently thicker at
the middle than at the edges of the fabric, and this fault increases with
the width of the fabric to be operated upon, as a corresponding increase in
the diameter of the rolls to give increased strength is found to be a dis-
advantage.
Our improvements consist in making the rolls which come in contact with
the fabric of the most convenient diameter, and in adding one or more rollers
to work against each roller in contact with the fabric, so as to sustain the
pressure coming thereon. All the rollers may be geered together, and those
in contact with the fabric may be made hollow and heated by steam or other
suitable means. The rollers are also provided with suitable doctors or
scrapers to remove any adhering matter.
The accompanying Sheet of Drawing illustrates the manner of carrying this
part of our improvements into effect. Fig. 1 is an end sectional view, and Fig. 2
a front view. a, side frames; b. roller pressing the material upon the fabric;
b', roller in contact with the cloth; b, upper supporting roller; and b³. lower
supporting roller. The rollers b' and b are in fixed bearings: but the bearings of
the rollers and b are in sliding frames c. Each frame (c) is connected with a
screw (c), arranged as shewn, by which screws the rollers b and b² can be either
lifted from or forced against the rollers below. The mill is driven by a
wheel (d) upon the end of the roller (6), and the other ends of all the rollers are
geered together by intermediate wheels d', geering with wheels d³ on the ends
of the rollers, as shewn in Fig. 2, and by dotted pitch lines in Fig. 1. The
rollers band 6' are hollow and heated by steam in any well-known way; e

page_text: are doctors or scrapers applied to the rollers to remove adhering matter.
These doctors have pivots, one at each end, which rest in bearings attached to
the side frames, and each doctor is pressed against the roller by set screws
The roller b
passing through brackets, also attached to the side frames.
which comes in contact with the material to be pressed upon the fabric is
acted upon by a rubber, formed by a beam extending across the roller and
carried at each end by an adjusting screw passing through a bracket secured to
a side frame. To the under side of the beam a part is secured by dovetails.
which is concave to the surface of the roller, and this surface is covered with
flannel or like material, and is supplied with oil or other lubricating matter.
This lubricating rubber prevents the roller from adhering to the material upon
the fabric. The material may be fed to and taken from the machine in the
same manner as in ordinary machines with two rollers. Machines according
to our Invention may be made with more than four rollers. Machines may
also be made as illustrated by the Diagram. Fig. 3, with two small rollers
b and b. to work in contact with the fabric, and with two supporting
rollers 2 and 3 of large diameter.
We have now particularly described the nature of our Invention, and the
mode of carrying the same into effect, and claim as our Invention,--
Firstly, the improved floorcloths formed of the compositions and in the
manner herein-before described.
Secondly, we claim for rolling adhesive materials upon fabrics, machines
having four or more rollers (b. b. b, and b) combined and arranged
substantially as herein-before described and illustrated in the accompanying
Drawings.
In witness whereof, we, the said John Howard Kidd and James Chadwick
Mather, have hereunto set our hands and seals, this Sixteenth day
of September, in the year of our Lord One thousand eight hundred
and sixty-five.
