PROVISIONAL SPECIFICATION left by the said George Davies at the
Office of the Commissioners of Patents, with his Petition, on the 10th
October 1859.
I, GEORGE DAVIES, of No. 1, Serle Street, Lincoln's Inn, in the County of
Middlesex, and No. 28, St. Enoch Square, in the City of Glasgow, Civil
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN
IMPROVEMENTS IN THE MANUFACTURE OF PAPER, PASTEBOARD,
AND CARDBOARD," (a communication from abroad by Messrs. Jules Lagosse and
Sons, Manufacturers, and Frederic Quentin, Merchant, all of Paris, France,)
to be as follows:-
This Invention relates to means designed to avoid (in machines for making
paper in continuous lengths) the tendency of the paper to adhere to the
pressing roller and to revolve with it, and, thus become crumpled, deteriorated, .

page_text: and torn, causing breaks and defects in the homogeneity and solidity of the
paper, in the clearness and beauty of its appearance, and in the smoothness
and softness of the touch, as well as irregularity in the color and other defects
which occasion great loss and trouble in this class of manufacture.
The Invention consists, firstly, in furnishing the pressing roller not only
with a
"doctor," intended to maintain the surface thereof constantly intact,
that is to say, free from plush, dust, or dirt of any kind, but also with a
"counter-doctor," resting on the upper surface of the roller facing the reel in
an oblique direction to the former so as to form a space, which can be
closed by a cover, and of which the surface of the roller forms a sort
of moving bottom; and secondly, in placing in this space one of the herein-
after mentioned substances, either in the state of pulp, juice, or liquor, which
will escape continually in a very small quantity between the "doctor" and the
roller, and will have the effect of maintaining the surface of the latter in a
permanent state of non-adherence as regards the paper, which will then follow
its own route on leaving the pressing roller.
These substances, which are very numerous, are principally the following,
employed either separately or mixed, namely, tubers, such as the potato; roots,
such as the beet or mangold; bulbs, such as the onion; fruits, such as the
melon, pumpkin; fleshy or farinaceous seeds and fruits; farina or flour in
general, such as that from cereals; fleshy leaves & stems of plants or
vegetables; bran tea, barm or yeast, non-resinous gums, certain acids, fresh
milk, the sap of vegetables, lean bacon, saliva, urine, and other articles, both
animal and vegetable, possessing similar properties.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Davies in the Great Seal Patent Office on the
10th April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
DAVIES, of No. 1, Serle Street, Lincoln's Inn, in the County of Middlesex,
and No. 28, St. Enoch Square, in the City of Glasgow, Civil Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of October, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto 3
me, the said George Davies, Her special licence that I, the said George

page_text: Davies, my executors, administrators, and. assigns, or such others as I, the
said George Davies, 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 PAPER, PASTEBOARD, AND CARDBOARD," (being a communi-
cation from abroad by Messrs. Jules Lagosse and Sons, Manufacturers, and
Frederic Quentin, Merchant, all of Paris, France,) upon the condition
(amongst others) that I, the said George Davies, my executors or adminis-
trators, 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 George Davies, 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 in writing, that is to say:-.
This Invention relates to means designed to avoid in machines for making
paper in continuous lengths, the tendency of the paper to adhere to the
pressing roller and to revolve with it and thus become crumpled, deteriorated,
and torn, causing breaks and defects in the homogeneity and solidity of the
paper, in the clearness and beauty of its appearance, and in' the smoothness
and softness of the touch, as well as irregularity in the colour and other defects
which occasion great loss and trouble in this class of manufacture.
The Invention consists, firstly, in furnishing the pressing roller not only with
a "doctor," intended to maintain the surface thereof constantly intact, that is
to say, free from plush, dust, or dirt of any kind, but also with a "counter-
doctor," resting on the upper surface of the roller facing the reel, in an
oblique direction to the former, so as to form a space which can be closed by
a cover, and of which the surface of the roller forms a sort of moving bottom;
and secondly, in placing in this space one of the herein-after mentioned sub-
stances, either in the state of pulp, juice, or liquor, which will escape con-
tinually in a very small quantity between the "doctor" and the roller, and
will have the effect of maintaining the surface of the latter in a permanent
state of non-adherence as regards the paper, which will then follow its own
route on leaving the pressing roller.
These substances, which are very numerous, are principally the following,

page_text: employed either separately or mixed, namely, tubers, such as the potato; roots,
such as the beet or mangold; bulbs, such as the onion; fruits, such as the
melon, pumpkin; fleshy or farinaceous seeds and fruits; farina or flour in
general, such as that from cereals; fleshy leaves and stems of plants and
vegetables; bran tea, barm or yeast, non-resinous gums, certain acids, fresh
milk, the sap of vegetables, lean bacon, saliva, urine, and other articles, both
animal and vegetable, possessing similar properties.
Having now described the nature and object of the said Invention for
improvements in the manufacture of paper, pasteboard, and cardboard,
together with the manner of carrying the same into practical effect, I would
remark, in conclusion, that I claim as the Invention communicated to me by
the said Messrs. Lagosse and Quentin, the application, use, or employment of
the means above described and set forth for preventing or avoiding the tendency
(in machines for making paper or other similar fabrics in continuous lengths)
of the paper to adhere to the pressing roller and revolve with it, thereby
becoming torn and otherwise deteriorated as aforesaid.
In witness whereof, I, the said George Davies, have hereunto set my
hand and seal, this Tenth day of April, in the year of our Lord One
thousand eight hundred and sixty.
GEORGE DAVIES. (L.S.)
