PROVISIONAL SPECIFICATION.
An Improved Method of Treating Peat Fibre for the Manufacture of
Paper Wrappers, Millboards, and the like.
JOSEPH AUGUSTUS LONDON 116 Sandyford Road Newcastle-on-Tyne Paper
Manufacturer, do hereby declare the nature of this invention to be as follows:
:-
I take the peat fibre direct to the beating potcher or breaking engine and mix
with the other material such as rope bagging waste papers and the like and add to
it the rosin size-the rosin size must contain free alkali which mixture I make as
follows, instead of 28 lbs. of 50% soda ash (or any other alkali of the same strength)
to 112 lbs. of powdered rosin, the proportions now used, I boil the rosin with 40 lbs.
of soda, this gives the free soda required to act upon the peat fibre in the engines.
The steam is then applied to the engines and heated up to a tem. of 80° Fah. to
150° Fah. this heat acting with the excess of soda increases or gives strength to
the peat fibres so acted upon-more of the coloring matter is also liberated for
dying purposes, improves the surface of the paper and assists the sizing.
The features of the novelty are 1st simplicity of application of the peat fibre
material, 2nd economy of working, 3rd good results.

JOSEPH AUGUSTUS LONDON 116 Sandyford Road Jesmond Newcastle-on-Tyne
Paper Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
I take the peat fibre direct to the beating, potcher, refining or breaking engine
and mix with the other material such as rope, bagging, waste jute, waste papers and
the like; and add to these materials the rosin size. The rosin size must contain free
alkali, which mixture I make as follows-Instead of 28 lbs. of 50% soda ash, or
any other alkali of the same strength, to 112 lbs. of powdered rosin, the proportions
now generally used, I boil the rosin with 40 lbs. of soda. This gives the free soda
required to act upon the peat fibre in the engines to discharge the coloring and
glutenous matter contained in the peat fibre, thereby assisting the sizing and coloring
of the paper giving a saving of coloring matter such as umber, ochre, mineral
black & the like also simplicity of application, improving the paper by handle,
strength, bear and feel and assists the water proof quality of the paper, as well as
cheapening the present cost of material now used. I then heat all the material or
mixture to from 80° Fah. to 212° Fah., to suit the class or quality of paper
required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
1. Simplicity of application of the neat fibre.

page_text: 3. Improving the paper by handle, strength bear & feel.
4. A saving in coloring matter, such as umber, ochre, mineral black and the
like.
5. Assists the water proof property of the paper.
