GEORGE NEWBERY.
COMPLETE SPECIFICATION.
An Improved Paper.
I, GEORGE NEWBERY of Windsor Court Strand, London, Gentleman, 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 :-
My Invention consists in an Improved paper so prepared that it can be written or
drawn upon with any hard pointed substance when marks will appear on the paper
similar to those marks made by an ordinary lead pencil upon ordinary paper.
My improved paper is prepared as follows. I first mix together the following
ingredients in the following proportions:-
To 9 lbs. or thereabouts of moist pipe clay or similar substance I add 2 ounces or
thereabouts of Russian tallow or other fatty matter, 14 lbs. or thereabouts of size is
added and 14 lbs. or thereabouts of Nix's black lead, (or of a lb. or thereabouts of
oxide of manganese) to the whole of the foregoing is added 2 gallons of water.
The black lead is ground on stone with a muller before being used I first mix
together the melted tallow with the clay which has been previously warmed to a
moderate temperature, and well beat and mix the same together.
I then add the size and afterwards the binck lead and the water and throughly mix
all well together and pass the mixture through a strainer of fine muslin. The liquid
mixture is then laid on to the surface of the paper with a brush and is followed by
another flat hair brush soaked with water known as a "Wetter" and which removes
any brush marks.
The paper is then hung up to dry and is ready for use.
I may if I desire it place my mixture as before described into the paper pulp befor
the paper is manufactured but an inferior result is obtained to that derived by the
process I have first described.
When a slight pressure is exerted by the point of a hard substance a mark appears
upon my improved paper as if made with a lead pencil. An ordinary lead pencil can
be equally well used.
The advantages are obvious as lead pencils may be despensed with when my improved
aner is used.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what [
claim is :-
An improved paper upon which marks or lines will appear similar to lead pencil
marks when it is pressed slightly by a hard substance, the said paper being prepared
or manufactured with the ingredients and in about the proportions hereintefore
specified in this specification.
