CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE OF PAPER
Year: 1861

page_text: LETTERS PATENT to Edward Partington, of Heap Bridge, in the County of
Lancaster, Manager, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE OF PAPER."
Sealed the 14th March 1862, and dated the 18th September 1861.
PROVISIONAL SPECIFICATION left by the said Edward Partington at the
Office of the Commissioners of Patents, with his Petition, on the 18th
September 1861.
I, EDWARD PARTINGTON, of Heap Bridge, in the County of Lancaster,
Manager, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE OF
PAPER," to be as follows:-
The Invention relates to that portion of the manufacture of paper when the
"material" is in the state called "half stuff," and is designed for the purpose
of separating the superfluous liquid from the "material" to prepare it for the
machine called the "willow."
The improvement consists in the employment of one or more pairs of bowls
or rollers, suitably supported in a framing, between which rollers the material
in the state of "half stuff" passes, and is pressed until sufficiently solidified for
the next operation. The "material" is fed to the rollers by means of an end-

page_text: less travelling cloth, and is received, after having been pressed by the rollers,
by another endless cloth. The upper roller is formed or composed of large discs
placed side by side and loose upon the central shaft, in order to allow any
portion of the roller to rise in the event of any solid matter passing between
the rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Partington in the Great Seal Patent Office on tho
15th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
PARTINGTON, of Heap Bridge, in the County of Lancaster, Manager, send
greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Iler
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edward Partington, Hor special license that I, the said Edward
Partington, my executors, administrators, and assigns, or such others as I, the
said Edward Partington, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE OF
PAPER," upon the condition, amongst others, that I, the said Edward Par-
tington, by an instrument in writing under my hand and seal, should particu-
larly 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 Edward Partington, 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 and accompanying Drawings (that is to say) :-
The Invention relates to that portion of the manufacture of paper when the
material" is in the state called "half stuff," and is designed for the purpose of

page_text: separating the superflous liquid from the "material" to prepare it for the
machine called the "willow and washing machine."
The improvement consists in the employment of one or more pairs of bowls
or rollers, suitably supported in a framing, between which rollers the "mate:
rial" in the state of "half stuff" passes, and is pressed until sufficiently solidi-
fied for the next operation. The "material" is fed to the rollers by means of an
endless travelling cloth, and is received, after having been pressed by the rollers,
by another endless cloth. The upper roller is formed or composed of large
discs placed side by side and loose upon the central shaft, in order to allow any
portion of the roller to rise in the event of any solid matter passing between
the rollers.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made upon a scale of
about one and a half inches to a foot, similar letters of reference being marked
upon corresponding parts of the apparatus.
Fig. 1 is an end view of the machine, shewing the method of feeding the
material between the compressing rollers or bowls by means of endless lattice
bands; Fig. 2 represents a front view of the machine taken at the "feeding"
end, shewing the large bowl composed of discs arranged side by side, and con-
structed as shewn in section in Fig. 3; Fig. 4 is a plan view; and Figs. 5 and
6 are detached views, shewing the adaptation and employment of two extra
compressing rollers to assist the larger bowl in expelling the aqueous portion
from the "material."
In the various Figures, a, a, is the framing of the machine, supporting the
bed roller b, and large disc or segmental bowl c; and d, d, are the traversing
cloths supplying the "material" in its wet state to the said rollers, and
removing it when the moisture has been sufficiently expressed. The lever and
weight fare for the purpose of regulating the amount of pressure required to
be exerted upon the "material," and g, g, is the gearing for driving the bowls
or rollers; the lattice band rollers being driven by the straps h, h.
In Figs. 5 and 6, i, i, are the extra rollers which, in some instances, are
required to act upon and prepare the material for the pressure of the heavier
bowl. Although I here describe the bowl 6 as formed of discs and loose upon
its shaft, with a layer or coating of india-rubber or any other elastic substance
between, yet I would remark, that a solid bowl may be employed in its stead,
similarly provided with an elastic medium between the shaft and bowl.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly

page_text: understood that I claim the novel employment and use of a bowl or bowls,
either segmental or solid, and loose upon their shafts, and having an elastic
medium between, and used in connection with other or "bed" bowls or rollers,
in order to effect the consolidation of the "half stuff," by expressing and sepa-
rating the aqueous portion therefrom, as herein-before described, set forth, and
fully illustrated in the Drawings attached.
In witness whereof, I, the said Edward Partington, have hereunto set my
hand and seal, this Fourteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-two.
EDWARD PARTINGTON. (L.S.)
