page_text: LETTERS PATENT to August Bruckner of St. James's Road Victoria Park
in the County of Middlesex for an Invention of A NEW OR IMPROVED
MATERIAL TO BE USED AS A CARPET LINING
PROVISIONAL SPECIFICATION left by the said August Bruckner at the
Office of the Commissioners of Patents on the 25th January 1883.
· AUGUST BRUCKNER of St James's Road, Victoria Park, in the County of
Middlesex
" A NEW OR IMPROVED MATERIAL TO BE USED AS A CARPET
LINING
"
The invention has for its object the production of a new or improved material to
be used as a carpet lining whereby the carpet placed over the same is better
protected from unevenness of the flooring and from dust whilst the elasticity of the
carpet under the foot is greatly improved.
For this purpose I take strong paper or a cheap woven or other fabric and spread
glue or other suitable cement over it and while the cement is still adhesive, I
distribute cork waste or granulated cork over the same said cork waste or granu-
lated cork, not being in the form of a dust or powder as such would not answer the
purpose, but being in the form of small pieces or chips sufficiently large to impart
a distinctly elastic character to the carpet lining and to permit of the dust and dirt
which passes through the carpet lodging between such pieces or chips and thereby
prevented from again coming into contact with the carpet.
If desired instead of using small chips or pieces of cork or granulated cork, as
above described, I cement thin strips or shavings of cork on to the surface of the
paper or other fabric.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said August Bruckner in the Great Seal Patent Office on the 25th
July 1883.

carpet under the foot is greatly improved.
For this purpose I take strong paper or a cheap woven or other fabric and spread
glue or other suitable cement over it and while the cement is still adhesive I
distribute cork waste or granulated cork over the same, said cork waste or granu-
lated cork not being in the form of a dust or powder as such would not answer the
purpose but being in the form of small pieces or chips sufficiently large to impart a
distinctly elastic character to the carpet lining and to permit of the dust and dirt
which pass through the carpet lodging between such pieces or chips and thereby
prevented from again coming into contact with the carpet.
If desired instead of using small chips or pieces of cork or granulated cork as
above described I cement thin strips or shavings of cork on to the surface of the
paper or other fabric.
I would here remark that the cork waste, granulated cork or strips or shavings
of cork must be applied as uniformly as possible over the surface of the backing
and the different pieces or particles thereof must be so close together as to form a
tolerably smooth and even surface, as in the event of any considerable space being
left between the particles of cork or the surface of the carpet lining being from any
cause made lumpy it will be injurious to the carpet and will therefore not answer
the purposes of my Invention.
If desired the cork may be cemented on to a compound backing formed of a sheet
of paper cemented on to a sheet of woven or other material.
After the application of the cork to the backing, the material is passed between
rollers or is otherwise pressed until the glue has become set or nearly so in order to
ensure the proper adhesion of the cork to the backing material.
If desired the back of the material can be painted in order to protect the same.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect I would have it understood that I do not claim the
cementing of cork dust or powder on to paper or other fabric as such would not
answer the purpose of my Invention being insufficiently elastic and moreover such
process has been used in the manufacture of imitation or artificial leather nor do I
claim the cementing of cork waste, granulated cork or strips or shavings of cork to
backing material when such material is applied unequally over the surface of the
backing as such process has been employed in the manufacture of packing material
for bottles and is useless for the purposes of my Invention but what I do claim is
the manufacture substantially as herein described of a new or improved material to
be used as a carpet lining.
In witness whereof I the said August Bruckner have hereunto set my hand
and seal this Twenty Third day of July in the year of our Lord One thousand
eight hundred and eighty three.
