PROVISIONAL SPECIFICATION.
Improvements in and applicable to Waterproof Compositions for Use
in the Manufacture of Roofing Felts, Brattice Cloths, Panels,
Linings, Imitation Veneers, and the like.
I, THOMAS THOMSON, of Westlea, Barrhead, in the County of Renfrew, North
Britain, Manufacturer, do hereby declare the nature of this invention to be as
follows, that is to say:-
-
My said invention has for its object the making of improved waterproof com-
positions which may be advantageously used in the manufacture of roofing
felts, brattice cloths, panels, linings, imitation veneers, and the like. Part of
my improvements being also applicable to felts and the like made from any
adhesive material.
My invention consists in employing as a principal ingredient of the com-
positions ground wood in a state of fine division. Where the composition is to
be used in the manufacture of felts, brattice cloths and the like I combine the
ground wood with tar, pitch, or any suitable resinous materials incorporating in
as much of the wood powder as the composition will carry. When it is desired
to produce a very strong composition I may add some flax, jute or cotton croppings,
caddis or lint. There may also be added lime or other suitable drier and any
suitable coloring matter.
The materials are intimately mixed together in a kneading or mixing machino
with or without the aid of heat. The composition is then spread or applied on
a web of any suitable material or it may be spread between two pieces of such
material or for certain purposes it may be run into sheets by itself without being
spread on a fabric, rollers being used in a manner usually practised with such
materials. For brattice cloths and the best qualities of roofing felt it is better
to spread the composition on a woven fabric.
In the manufacture of panels, linings, imitation veneers, and the like I com-
bine the ground wood with a fine varnish with or without coloring and drying
materials and spread the same on a millboard or on a thin fabric, paper or the
like.
The surfaces of felts and the like made as herein before described or from any
other adhesive materials may according to my invention be dusted with the
wood powder to act in filling them up and also to prevent such surfaces from
adhering or sticking together when rolled up.
Dated this Twentieth day of October 1898.

I, THOMAS THOMSON, of Westlea, Barrhead, in the County of Renfrew, North

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say: -
My said invention has for its object the making of improved waterproof com-
positions which may be advantageously used in the manufacture of roofing
felts, brattice cloths, panels, linings, imitation vencers, and the like. Part of
my improvements being also applicable to felts and the like made from any
adhesive material.
My invention consists in employing as a principal ingredient of the com-
positions ground wood in a state of fine division. Where the composition is to

The surfaces of felts and the like made as herein before described or from any
other adhesive materials may according to my invention be dusted with the
wood powder to act in filling them up and also to prevent such surfaces from
adhering or sticking together when rolled up.
The powdered wood either when to be used as an ingredient of the water-
proof compositions, or when to be applied to the surfaces of such compositions
may be colored either by dyeing or by mixing with suitable pigments.
Having now particularly described and ascertained the nature of my said
invention and the manner of performing the same I declare that what I
claim is:
1. Making improved compositions with the ingredients in the manner, and
for the purposes substantially as herein before described, a principal ingredient
being ground wood in a state of fine division.
2. In the application of compositions for roofing felts, brattice cloths, panels,
linings, imitation veneers, and the like dusting the surfaces thereof with wood
powder substantially as and for the purposes herein before described.
