PROVISIONAL SPECIFICATION left by the said Frederick Brampton at
the Office of the Commissioners of Patents, with his Petition, on the
14th January 1867.
I, FREDERICK BRAMPTON; of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for "A NEW
OR IMPROVED COMPOUND MATERIAL OR SUBSTANCE TO BE USED FOR BINDING BOOKS!
FOR PANELLING, AND FOR OTHER PURPOSES WHERE STRENGTH AND LIGHTNESS ARE
REQUIRED," to be as follows:-
My Invention consists of a compound material or substance made by coating
or covering millboard on one or both sides with veneers or thin layers of wood,
which said compound material or substance is very strong and very light, and
is well adapted for covers of books, for panels, and for a great variety of other
purposes.
In making the said compound material or substance I take, by preference,
millboard of the kind commonly called panel board, and which consists of
millboard made from the fibre of cotton and steeped in drying oil, and stoved
or dried: I also take thin veneers of wood, and by means of glue or other.
adhesive material I glue or affix the said veneers to one or both sides of the
Price S.1

page_text: said millboard. The surface of the veneer may be smoothed and varnished or
polished or ornamented in any desired manner. The veneers cumploy may
either be cut from blocks of one kind of wood or from blocks composed of
several kinds of wood so glued or joined together as to produce when cut into
veneers ornamental patterns or designs.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Brampton in the Great Seal Patent Office on the
9th July 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1. FREDERICK
BRAMPTON, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did. for Herself. Her heirs and successors, give and grant unto me, the
said Frederick Brampton. Her special licence that I, the said Frederick
Brampton, my executors, administrators, and assigns, or such others as I, the
said Frederick Brampton, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time, and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "A NEW OR
IMPROVED COMPOUND MATERIAL OR SUBSTANCE TO BE USED FOR BINDING BOOKS, FOR
PANELLING, AND FOR OTHER PURPOSES WHERE STRENGTH AND LIGHTNESS ARE
REQUIRED," upon the condition (amongst others) that I, the said Frederick
Brampton, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Frederick Brampton, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:
My Invention consists of a compound material or substance made by coating

page_text: or covering millboard on one or both sides with veneers or thin layers of wood.
which said compound material or substance is very strong and very light, and
is well adapted for covers of books. for panels, and for a great variety of other
purposes.
In making the said compound material or substance take, by preference.
millboard of the kind commonly called panel board, and which consists of
millboard made from the fibre of cotton and steeped in drying oil, and stoved
or dried: I also take thin veneers of wood. and by means of glue or other
adhesive material, glue or affix the said veneers to one or both sides of the
said millboard. The surface of the veneer may be smoothed and varnished or
polished, or ornamented in any desired manner-The veneers I employ may
be cut from blocks of one kind of wood. or from blocks composed of
several kinds of wood so glued or joined together as to produce when cut into
veneers ornamental patterns or designs.
Having explained the nature of my Invention I will proceed 10 describe
the manner in which the same is to be performed. I coat one side of the
veneer with glue melted or prepared in the ordinary way, and I allow the
coating of glue to become thoroughly dry by exposure to the air or by the
application of a gentle heat. I similarly coat with glue on one side of the
millboard, and allow the coating of glue to become thoroughly dry by exposure
to the air or by the application of a gentle heat. The vencer and millboard
thus prepared may be kept any length of time. When it is wished to attach
the vencer to the millboard I take the millboard and very slightly damp its
glued surface with water, which may be applied by a sponge or a piece of
flannel; in damp weather the application of water to the glued surface of
the millboard is unnecessary. I place the veneer on the millboard, the two
glued surfaces being in contact, and place upon the veneer a hot block.
that is, a block of iron heated to a temperature of about 200 degrees Fahrenheit,
and I subject the whole to pressure for a few seconds; the pressure may be
applied by a hydraulic or other press, and should not be less than five or
six hundred pounds to the square inch. The heat of the hot block acting
through the veneer causes the damped and glued surface of the millboard
to attach itself firmly to the glued surface of the veneer. The pressure
need not be applied more than five or six seconds if the veneer be very
thin, but if the veneer be thick the pressure must be applied for a longer time.
By attaching the two surfaces together in the manner described no warping is
produced.
My improved compound material or substance may be used in the manu-
facture of articles having either flat or curved surfaces. When it is to be

page_text: applied to articles having curved surfaces. the material is gently warmed and
bent into the required shape, and is retained in the required shape under
pressure until it has cooled and set. Where the millboard has to be coated
on both sides with veneer both sides of the millboard are coated with glue
and dried, and after the veneer has been attached to one side of the mill-
board, in the manner herein before described, the veneer is afterwards
attached to the other side in a similar manner; or both of the glued sides
of the millboard may be damped, and the glued surfaces of the veneers applied
to either side at the same time, the veneers on the millboard being placed
between two hot blocks during the application of pressure.
Although have described the best method with which i am acquainted
of attaching the veneer and millboard together, yet I do not limit myself
thereto, as they may be attached in other ways with nearly the same effect.
Although prefer using millboard in carrying my Invention into effect, yet
pasteboard or stout paper may be employed in place of millboard.
But the new or improved compound material or substance produced when
pasteboard or stout paper is used in place of millboard is inferior to that
produced when millboard is employed.
Having now described the nature of my Invention, and the manner in which
the same is to be performed, I wish it to be understood that 1 claim as my
Invention, the new or improved compound material or substance to be used for
binding books, for panelling, and for other purposes where strength and lightness
are required, herein-before described, that is to say, a compound material or
substance made by coating or covering millboard or pasteboard on
or both sides with vencers or thin layers of wood, substantially as herein-
before described.
In witness whereof, I. the said Frederick Brampton, have hereunto set
my hand and seal, this Eighth day of July, in the year of our Lord
One thousand eight hundred and sixty-seven.
Witness.
