IMPROVEMENTS IN THE MANU- FACTURE OF FLOORCLOTH, ROOF AND OTHER WATERPROOF COVERING, AND IN THE MEANS OR APPARATUS EMPLOYED THEREIN
Year: 1876

page_text: LETTERS PATENT to John Sanderson Norrie, of Dundee, in the County of
Forfar, Manufacturer, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF FLOORCLOTH, ROOF AND OTHER WATERPROOF COVERING, AND IN
THE MEANS OR APPARATUS EMPLOYED THEREIN."
Scaled the 30th September 1876, and dated the 31st May 1870
PROVISIONAL SPECIFICATION left by the said John Sanderson Norric at the
Office of the Commissioners of Patents on the 31st May 1876.
JOHN SANDERSON NORRIE, of Dundee, in the County of Forfar, Manufacturer.
"IMPROVEMENTS IN THE MANUFACTURE OF FLOORCLOTH, ROOF AND OTHER WATER-
PROOF COVERING, AND IN THE MEANS OR APPARATUS EMPLOYED THEREIN."
The Invention relates to the use of asphalte or other bituminous matter in
combination with cotton or linseed oil or other suitable oleaginous substance with
textile or other fabric for the production of a fabric adapted as a covering for the
floor or for roofs and other surfaces.
The proportions of oil to bituminous matter I find to answer well are one gallon
of oil to one hundred and sixty pounds of bitumen, but I do not confine myself to
these proportions.
The combination of matters is to be applied uniformly over the whole surface of
the fabric; and this may be effected by land aided by the use of spreading irons or
other suitable means by which the material may be quickly and uniformly laid
whilst hot.
Coloring matter may be mixed with the bituminous compound if desired, in mass
or in streaks, to resemble marble, or by printing or otherwise.
One arrangement of apparatus I employ as a means of applying the bituminous
compound to the fabric consists of a trough or receiver of length sufficient for the
width of the fabric to which the compound is to be applied, and in which the
bituminous compound is kept heated to a fluid or semi-fluid state. This trough is
provided with an opening capable of being regulated in length and width to the
width of fabric on which the compound is to be laid, and the thickness of it for the
time to be applied, and it is capable of movement over such fabric to lay the
bituminous matter thereon whilst that fabric is being held on a suitable table,
the contents of the trough being allowed to flow out to the extent desired during
such movement. The surface obtained is then rolled to secure uniformity in the
application.

page_text: According to another arrangement the fabric to which the application is to be
made is passed through the bituminous mixture as that is held in a fluid or semi-
fluid state by being heated in a trough or receiver, and which trough or receiver is
provided with scrapers and rollers for the regulation of the required amount of
coating, so as to secure an even surface to it when applied.
According to another arrangement the fabric to which the application is to be
made is passed over a heated cylinder or roller, part of whose surface dips into the
bituminous compound, and in its revolution applies it to the surface of the fabric,
scrapers and rollers being used to regulate the quantity and secure uniformity of
surface.
The bituminous compound may be applied to either one or both sides of the
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Sanderson Norrie in the Great Seal Patent Office on the 29th
November 1876.

fabric, as desired.
The printing may be effected by blocks, or rollers, or otherwise.
Having thus described my Invention and means which I adopt in carrying the
same into effect, I would have it understood that what I claim is, the manufacture
of floorcloth, roof and other waterproof covering, and in the means or apparatus
employed therein, substantially as herein described.
In witness whereof, I, the said John Sanderson Norrie, have hereunto set my
hand and seal, this Twenty-second day of November, in the year of our Lord
One thousand eight hundred and seventy-six.
