PROVISIONAL SPECIFICATION.
Improvements in Paper Making Machines.
I, JOSHUA SUMNER of Greenway Street, Darwen, in the County of Lancaster,
Paper Maker do hereby declare the nature of this invention to be as follows: Y
This invention relates to improvements in what are known as the second press:
felts employed in paper making machines, such "felts" as heretofore constructed
of felt, linen, or other woven or fibrous substance, have many disadvantages, such
as absorbing the colouring matter from the paper when making coloured papers,
and so requiring washing whenever the colour or shade of paper was changed, and
not having a smooth surface, the face of the paper which came in contact therewith,
when passing through the press rollers, was marked or slightly roughened by
receiving an impression from the surface of the felt.
According to this my said invention, I construct the improved felts of linen
or other woven fabric, and face or cover one side of same with rubber or other
similar substance, which is capable of receiving a highly glazed or smooth surface,
and also waterproof, so that no colouring matter is absorbed by the improved felt,
and the face of the paper is not in any way roughened or damaged by passing
between the smooth surface of the "felt" and the press rolls, the latter also are
found in practice to remain clean, no crust or sediment forming thereon, and the
felts are much more durable and effective than those now used, and seldom require
washing or cleaning.
Dated this 3rd day of February 1892.

COMPLETE SPECIFICATION.
Improvements in Paper Making Machines.
1, JOSHUA SUMNER of Greenway Street, Darwen, in the County of Lancaster
Paper Maker, 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 :-
"
This invention relates to improvements in what are known as the second press
"felts "employed in paper making machines, such "felts as heretofore constructed
of felt, linen, or other woven, or fibrous substance, have many known disadvantages
such as absorbing the colouring matter from the paper when making coloured
paper, and so requiring washing whenever the colour, or shade of the paper was
changed, and not having a smooth surface the face of the paper which came in
contact with the "felt when passing through the press rollers was marked or
slightly roughened by receiving an impression from the surface of the "felt.".
"
According to this invention I construct the "felts of linen, or other woven
fabric, and face or cover one side of same with rubber or other substance capable
of receiving a highly glazed smooth, and waterproof surface.
Such being the nature, and object of the said invention the following is a
complete description of same.
According to this invention I construct the improved "felt" of linen, or other
woven fabric, or felt, and face or cover one side of same with rubber or other
similar substance which is capable of receiving a highly glazed and smooth surface,
and also waterproof. By making the surface waterproof no colouring matter is
.

page_text: absorbed by the improved "felt," consequently the "felt." is more durable and
requires washing only at long intervals. The smooth glazed surface does not in
any way damage, roughen, or mark the paper as it passes between the "felt" and
the press rolls. In practice it is found that the "felt" remains clean for a long
time, no crust or. sediment forming thereon, and is more durable, and effective than
those heretofore used.
Having now particularly described and ascertained' the nature, and object of the
said invention, and in what manner the same is to be employed I declare that
what I claim is:-
In paper making machines, the improved "felt" composed of linen, or other
woven fabric, and having a waterproof, and smooth glazed surface as and for the
purpose herein described.
