Year: 1858

page_text: LETTERS PATENT to Thomas Whiteley, of Stainland, in the Parish of
Halifax, in the County of York, Paper and Millboard Manufacturer, for
the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF MILLBOARD, AND
IN MACHINERY OR APPARATUS FOR CUTTING MILLBOARD AND PAPER."
Sealed the 31st December 1858, and dated the 1st July 1858.
PROVISIONAL SPECIFICATION left by the said Thomas Whiteley at the
Office of the Commissioners of Patents, with his Petition, on the
1st July 1858.
I, THOMAS WHITELEY, of Stainland, in the Parish of Halifax, in the County
of York, Paper and Millboard Manufacturer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF MILLBOARD,
AND IN MACHINERY OR APPARATUS FOR CUTTING MILLBOARD AND PAPER," to be
as follows:-
My Invention relates, firstly, to the manufacture of millboard composed of
different qualities and colors of materials, and consists in so arranging and
working the machinery or apparatus used for grinding and washing the various
pulps simultaneously and in juxtaposition, that I am enabled to make the
middle portion of the millboard of inferior or coarse material, and the outside
of a finer quality and of a different color, as may be required.
Heretofore paper or pasteboard (resembling millboard) has been made by
first forming a millboard middle of coarse or inferior pulp, with the outsides of

page_text: a finer quality and of different colors, but in the process of manufacture each
part when formed had to be dried and rolled, and then pasted together, but by
my improvements millboard of various qualities and colors can be manu-
factured at one operation, thereby saving the time required to dry the separate
sheets, and also the cost of rolling, pasting, &c.
This part of my Invention is performed by having several washing and
breaking or grinding engines arranged side by side, or in such other relative
positions that they can be worked simultaneously, in order that one or more
of the engines can be operating upon one quality or color of materials, whilst
other engines are operating upon other qualities or colors, the products
thereof being conducted to their respective "pulp chests" and "vats," which
are placed side by side, or in such relative positions that one workman or
more can be forming or making the middle layers of pulp from coarse
materials, whilst other workmen are forming or making the outside layers of
finer qualities of pulp or of different colors as may be required, each man placing
his layer of formed pulp in the proper relative position on the same pile to
form one millboard, according to the thickness, quality, or variety of color that
may be required.
Secondly, this Invention relates to machinery or apparatus employed for
cutting off the edges of millboards and paper to form the proper size of sheets,
and consists in the application of a straight-edged knife, set or arranged so as
to be at an angle with the bed of the machine or press in which the millboard
is placed for cutting, and imparting to such knife a slide cut by means of
crank and connecting rod, with suitable guides for the knife.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Whiteley in the Great Seal Patent Office on the
31st December 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WHITELEY, of Stainland, in the Parish of Halifax, in the County of York,
Paper and Millboard Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of July, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Whiteley, Her special licence that I, the said Thomas Whiteley,
my executors, administrators, and assigns, or such others as I, the said

page_text: Thomas Whiteley, 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 "IMPROVEMENTS IN
THE MANUFACTURE OF MILLBOARD, AND IN MACHINERY OR APPARATUS FOR CUTTING
MILLBOARD AND PAPER," upon the condition (amongst others) that I, the
said Thomas Whiteley, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion 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 Thomas Whiteley, do hereby declare
the nature of my 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 (that is to say):-
My Invention relates, firstly, to the manufacture of millboard composed of
different qualities and colors of materials, and consists in so arranging and
working the machinery or apparatus used for grinding and washing the various
pulps simultaneously and in juxtaposition, that I am enabled to make the
middle portion of the millboard of inferior or coarse material, and the outside
of a finer quality and of a different color, as may be required.
Heretofore paper or pasteboard (resembling millboard) has been made by
first forming a millboard middle of coarse or inferior pulps, with the outsides of
a finer quality and of different colors, but in the process of manufacture each
part when formed had to be dried and rolled, and then pasted together, but by
my improvements millboard of various qualities and colors can be manu-
factured at one operation, thereby saving the time required to dry the separate
sheets, and also the cost of rolling, pasting, &c.
This part of my Invention is performed by having several washing and
breaking or. grinding engines arranged side by side, or in such other relative
position that they can be worked simultaneously, in order that one or more.
of the engines can be operating upon one quality or color of materials, whilst
other engines are operating upon other qualities or colors, the products
thereof being conducted to their respective "pulp chests" and "vats," which
are placed side by side, or in such relative positions that one workman or
more can be forming or making the middle layers of the pulp from coarse
materials, whilst other workmen are forming or making the outside layers of
finer qualities of pulp or of different colors, as may be required, each man

page_text: placing his layer of formed pulp in the proper relative position on the same
pile to form one millboard, according to the thickness, quality, or variety of
color that may be required.
Secondly, this Invention relates to machinery or apparatus employed for
cutting off the edges of millboard and paper to form the proper size of sheets,
and consists in the application of a straight-edged knife set or arranged so as
to be at an angle with the bed of the machine or press in which the millboard.
is placed for cutting, and imparting to such knife a slide cut by means of a
crank and connecting rod, with suitable guides for the knife.
My said Invention will be clearly understood by reference to the accom-
panying two Sheets of Drawings, and the letters of reference thereon.
Fig. 1, Sheet 1, is an elevation of the machinery or apparatus I employ for
manufacturing millboard, constructed and arranged suitably for the carrying
out of this part of my Invention, and Fig. 2 is a plan of the same.
A, B, C, D, are the washing and breaking or grinding engines, which are all
driven by spur pinions gearing in with the main driving wheel E. The
products or pulps are conducted by pipes to the pulp chests F, G, H, from
which they are drawn away by other pipes to the vats I, K, L. It will be
seen that whilst one, two, or three of the engines are employed in grinding
inferior materials for the middles, the other may be employed in grinding a
fine quality or colored material for outsides, the products of each being
conducted to separate pulp chests for supplying their respective vats. The
conducting pipes from the upper engines are flexible, so that I can readily
change them from one to the other of the lower engines, and the pipes from
the engines to the pulp chests and vats are supplied with sluices or stop
valves, so as to change the course or flow of the pulp to any of the chests or
vats as may be required; or flexible pipes may be employed.
It will also be readily seen that if a fine quality of pulp be conducted to the
vat K, and an inferior quality to the vats I, L, the makers at K would pass
their "dips" to each pile or piller M, N, whilst the makers at I would pass to M,
and the makers at L will pass to N, according to the number of dips or layers
of each required; by which means or arrangement I am enabled to make mill-
board of different qualities or colors of material at one operation.
The second part of my said Invention will be understood by reference to
Sheet 2 of the accompanying Drawings, where Fig. 1 is an end elevation, and
Fig. 2 is a front elevation of the machine for cutting off the edges of millboard
and paper. A are the end frames; B, the bed of the machine, on which
millboards, &c., are laid for cutting; C is a presser forced down by the screws
D, bevil gear E, and shaft F, with the hand wheel G for holding the materials

page_text: in position; H is a knife set at an angle with the bed, the motion of which is
derived through the crank I and connecting rod J by the train of spur and
bevil gear from the driving pullies K. The knife is caused to slide in an
oblique manner by the studs L, which are guided by the slot plates M affixed
to the frame of the machine.
Having thus fully described the nature of my said Invention, and the
manner in which the same is performed, I would have it distinctly under-
stood that what I claim as my Invention and believe to be new within the
realm is,
-
Firstly, the manufacture of millboard of various qualities and colors of
materials at.one operation.
Secondly, the construction and general arrangement of apparatus for such
purposes as herein described and illustrated in No. 1 Sheet of Drawings.
Thirdly, the construction and general arrangement of machinery or apparatus
for cutting millboard and paper, as herein described and illustrated in No. 2
Sheet of Drawings.
In witness whereof, I, the said Thomas Whiteley, have hereunto set my
hand and seal, this Twenty-ninth day of December, in the year of
our Lord One thousand eight hundred and fifty-eight.
Signed, sealed, and delivered by the
within-named Thomas Whiteley,
in the presence of
THOMAS WHITELEY. (L.S.)
