AN IMPROVED FABRIC SUITABLE FOR CARPET LININGS AND OTHER PURPOSES, AND IMPROVED MACHINERY FOR MANUFACTURING THE SAME
Year: 1870

page_text: LETTERS PATENT to William Henry Maitland, of Thurloe Square, in
the County of Middlesex, for the Invention of "AN IMPROVED FABRIC
SUITABLE FOR CARPET LININGS AND OTHER PURPOSES, AND IMPROVED MACHINERY
FOR MANUFACTURING THE SAME."
Sealed the 31st January 1871, and dated the 7th December 1870.
PROVISIONAL SPECIFICATION left by the said William Henry Maitland
at the Office of the Commissioners of Patents, with his Petition, on
the 7th December 1870.
I, WILLIAM HENRY MAITLAND, of Thurloe Square, in the County of
Middlesex, do hereby declare the nature of the said Invention for "AN
IMPROVED FABRIC SUITABLE FOR CARPET LININGS AND OTHER PURPOSES, AND
IMPROVED MACHINERY FOR MANUFACTURING THE SAME," to be as follows:-
-
My improved fabric is manufactured as follows:-I apply size to one
side of wadding in the ordinary manner, and while the size is still wet I
lay upon it paper, preferably in the state of a continuous, sheet, and I:
then submit the wadding with the paper thereon to. pressure between
rollers, or otherwise; I next reverse the wadding, apply size to the

page_text: opposite side, lay paper on that side, and again submit the fabric to
pressure. I thus obtain a fabric composed of wadding enclosed between
two sheets of paper.
The improvement in machinery for making my improved fabric
consists in the addition to ordinary wadding machinery of a roller for 5
containing and delivering the continuous sheet of paper, and of rollers
between which the fabric is submitted to pressure, the said rollers being
mounted in suitable bearings.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Henry Maitland in the Great Seal Patent
Office on the 6th June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY MAITLAND, of Thurloe Squaro, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Seventh day of December, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Henry Maitland, Her special licence
that I, the said William Henry Maitland, my executors, administrators,
and assigns, or such others as I, the said William Henry Maitland, 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 "AN IMPROVED FABRIC
SUITABLE FOR CARPET LININGS AND OTHER PURPOSES, AND IMPROVED MACHINERY
FOR MANUFACTURING THE SAME," upon the condition (amongst others) that I,
the said William Henry Maitland, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and a
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
Patent.

page_text: NOW KNOW YE, that I, the said William Henry Maitland, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the ac-
companying Drawing, that is to say:-
My improved fabric is manufactured as follows:-I apply size to one
side of wadding in the ordinary manner, and while the size is still wet I
lay upon it paper, preferably in the form of a continuous sheet, and I
then submit the wadding with the paper thereon to pressure between
rollers or otherwise; I next reverse the wadding, apply size to the
opposite side, lay paper on that side, and again submit the fabric to
pressure. I thus obtain a fabric composed of wadding enclosed between
two sheets of paper. The two sheets of paper, or either of them may,
if desired, be coated with liquid gutta percha.
The improvement in machinery for making my improved fabric
consists in the addition to ordinary wadding machinery of a roller for
containing and delivering the continuous sheet of paper, and of rollers
between which the fabric is submitted to pressure, the said rollers being
mounted in suitable bearings.
This improvement in the machinery will be understood from the
accompanying Figure, in which a represents an inclined frame forming
part of the wadding machinery; b is a roller mounted loosely in
bearings c; & represents the wadding, which coming from the ordinary
parts of the machine passes round the roller b, where the size is applied
to one side of it by hand in the usual manner. The wadding is then
carried up by a travelling web or creeper e to a roller f, where it meets
with a continuous sheet of paper g, given off from a roller h. The
wadding & and the superposed paper 9 pass together between the
roller and a pressing roller f, the pressure of which may, if
necessary, be made adjustable in any ordinary manner. The wadding
and paper pass from these rollers into the ordinary drying box. When
dry the wadding with the paper is again passed through the parts of
the machinery above described, but reversed, the size being now applied
to the opposite side of the wadding, upon which side paper is then laid
as before. A fabric is thus obtained composed of wadding enclosed
between two layers or sheets of paper, as has been already explained.
The web or creeper e passes round a roller i as well as round the roller ƒ,
and either of these rollers is driven at the proper speed in any ordinary
r

page_text: way; k, k, are rollers covered with india-rubber or other elastic or
yielding material, between which the continuous sheet of paper 7 passes
after leaving the roller ; one of these rollers kis driven at the same
speed as the rollers fand i, so that the paper is fed at the same speed as
the wadding.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,—
First. The improved fabric, composed of wadding enclosed between
two sheets or layers of paper, as herein-before described.
Second. The improved machinery, herein-before described, for manu- ]
facturing the said fabric.
In witness whereof, I, the said William Henry Maitland, have here-
unto set my hand and seal, this Fifth day of June One thousand
eight hundred and seventy-one.
