IMPROVEMENTS IN THE MANUFACTURE OF CARPETS AND FLOOR COVERINGS FROM PEAT, BARK, CELLULOSE AND SIMILAR MATERIALS
Year: 1884

page_text: I, GERARD WENZESLAUS VON NAWROCKI, Proprietor of the firm of J. Brandt and
G. W. von Nawrocki, Patent Solicitor and Civil-Engineer, of 124, Leipzigerstrasse,
Berlin, Germany, do hereby declare the nature of said Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF CARPETS AND FLOOR COVERINGS FROM PEAT, BARK,
CELLULOSE AND SIMILAR MATERIALS," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Peat, (turf) peat fibre, peaty earth, cellulose, tan and similar materials mixed in
various proportions, or each of these materials separately, are disintegrated by
means of any suitable machine, and thoroughly mixed, by machinery; with binding
substance such as rosin, oil and fat, with or without the addition of oil paint, water
colours or fatty paints, until the whole is converted into a plastic elastic paste.
This pasty mass is then spread, either by hand or machine, in a uniform layer of
any suitable thickness on a specially prepared woven fabric which forms the base
or back of the carpet, after which the whole is smoothed and strongly pressed by
means of rollers and thereby converted into a smooth mass the back of which is
a tissue while the surface or right side consists of a smooth, mass of peat, peat
fibre, peaty earth, cellulose, tan etc. according to the materials used together or
separately in the mixture of the paste.
Instead of smooth rollers, engraved rollers or plates may be used for pressing,
whereby the surface of the product becomes figured or embossed with the design
engraved on the rollers.
The product, thus obtained in pieces of any desired length or breadth, is then
dried by cold and hot air and may be subsequently printed on, by means of engraved
plates or rollers made of brass or wood, with any suitable oil, fat, or water colours
so as to represent any desired coloured pattern; or the surface of the dried product
may be lined with woven fabrics.
Although peat, peat fibre, peaty earth, cellulose, tan and similar materials, used
together or separately, form the foundation or raw material in this process,

page_text: various quantities of other materials may be mixed with the same without departing
from the Invention; for instance wool-cotton-linen-jute and cork waste, cow's
hair, wool dust and similar material in a ground or disintegrated state.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The use of peat or peat fibre, either alone or mixed with peaty earth,
cellulose, tan and similar materials for the manufacture of carpets and floor
coverings, substantially as described.
2. The manufacture of carpets and floor coverings, either plain or printed, smooth
or embossed, or lined with woven fabric, from peat, peat fibre, cellulose, tan and
similar materials, by taking any of these raw materials separately or a mixture of
two or more of the same and forming them into an elastic and solid mass by means
of rosin, oil, fat or similar binding substance and uniting this mass with a base of
woven fabric, substantially as described.
