Year: 1882

page_text: LETTERS, PATENT to John Harcourt Browne of Cleobury Mortimer, in the
county, of Salop, Paper Manufacturer for an invention of "IMPROVEMENTS
IN THE MANUFACTURE OF PANELS, BOARDS, BOBBINS, ARTIFICIAL LEATHER
SHEETS AND WEBS, AND THE LIKE"
PROVISIONAL SPECIFICATION left by the said John Harcourt Browne at
the Office of the Commissioners of Patents on the 16th June 1882.
JOHN HARCOURT BROWNE, of Cleobury Mortimer, in the county of Salop, Paper
Manufacturer “IMPROVEMENTS IN THE MANUFACTURE OF PANELS, BOARDS,
BOBBINS, ARTIFICIAL LEATHER SHEETS AND WERS, AND THE LIKE"
This invention relates to improvements in the manufacture of panels, boards,
bobbins, artificial leather sheets and webs and the like in a better and more
economical manner than hitherto.
In carrying out these improvements I take suitable quantities of chamois or
wash leather cuttings, or curriers' shavings, and after they have been sorted
according to the class of article I wish to produce, I well wash them in any suitable
washing or cleansing apparatus and then reduce the pieces to pulp in any suitable
manner. The pulp thus prepared is when necessary bleached in a similar manner
to that usual in the manufacture of paper.
From the pulp made in this way from chamois or wash leather, curriers' shavings,
rags, waste papers and wood pulp, either separately or in combination I manu-
facture by moulding or otherwise sheets, webs, boards, panels, school black boards,
bobbina and the like.
Railway and other carriage panels, black-boards, and bobbins after being made
into the required form are dried, and after being rolled or pressed, I treat them with
linseed or other suitable oil, and expose them to a high temperature.
In manufacturing bobbins for working silk, cotton, worsted, or other fibres, I press
the pulp into the required shapes in moulds or other suitable appliances, then treat
ID 31

page_text: them with oil as aforesaid and harden them by baking, after which they can be
finished by being turned in a lathe or any other suitable manner. When it is
required that sheets or webs are to be prepared to receive colouring or any other
dressing on the surface, or when they are to be prepared for printing or writing
upon, I either add to the pulp, size made in the usual way from rosins and 5
alkalies or I dip or pass the sheets or webs through size made from animal matter
in the same way as paper is sized.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Harcourt Browne in the Great Seal Patent Office on the
13th December 1882.
JOHN HARCOURT BROWNE of Cleobury Mortimer, in the county of Salop, Paper
Manufacturer "IMPROVEMENTS IN THE MANUFACTURE OF PANELS, BOARDS,
BOBBINS, ARTIFICIAL LEATHER SHEETS AND WEBS, AND THE LIKE”
This invention relates to improvements in the manufacture of panels, boards,
bobbins, artificial leather sheets, and webs and the like in a better and more
economical manner than hitherto.
In carrying out these improvements I take suitable quantities of chamois or
wash leather cuttings or curriers' shavings and after they have been sorted
according to the class of article I wish to produce I well wash them in any suitable
washing or cleansing apparatus and then reduce the pieces to pulp in any suitable
manner. The pulp thus prepared is when necessary bleached in a similar manner
to that usual in the manufacture of paper.
From the pulp made in this way from chamois or wash leather, curriers' shavings,
rags, waste papers and wood pulp, either separately or in combination, I manu-
facture, by moulding or otherwise, sheets, webs, boards, panels, school black boards,
bobbins and the like.
Railway and other carriage panels, black boards and bobbins after being made
into the required form are dried, and after being rolled or pressed, I treat them
with linseed or other suitable oil, either by soaking them in the oil or by rubbing
the oil into them and then expose them to a temperature of about two hundred
degrees Fahrenheit.
In manufacturing bobbins for working silk, cotton, worsted or other fibres I press
the pulp into the required shapes in moulds or other suitable appliances, then treat
them with oil as aforesaid and harden them by baking after which they can be
finished by being turned in a lathe or any other suitable manner.
Blackboards for school purposes after being baked or hardened are prepared by
scraping or smoothing the surfaces in any suitable manner and then covering them
with any suitable colouring matter or composition such as the German slate
mixture or a composition composed of shellac, spirits of wine or any other suitable
solvent and any suitable black colouring matter.

page_text: When it is required that sheets or webs are to be prepared to receive colouring
or any other dressing on the surface, or when they are to be prepared for
printing or writing upon, I either add to the pulp (made from chamois or wash
leather cuttings or curriers' shavings either separately or together or in combi-
nation with raga, waste papers or wood pulp) size made in the usual way from
rosins and alkalies, or I'dip or pass the sheets or webs through size made from
animal matter in the same way as paper is sized and I either add alum to the pulp
after the size or dissolve and mix it with the size as may be necessary.
Having thus described my said invention and the best means with which I am
acquainted for carrying the same into effect I wish it to be understood that what I
claim is :-
The improvements in the manufacture of panels, boards, bobbins, artificial leather
sheets and webs and the like as hereinbefore described.
In Witness whereof I the said John Harcourt Browne have hereto set my hand
and seal this twelfth day of December in the year of our Lord one
thousand eight hundred and eighty two
