IMPROVEMENTS IN AWWWCTED OF DADDY
Year: 1869

page_text: LETTERS PATENT to Ramsay Allan, of Kelvindale, in the County of
Lanark, North Britain, for the Invention of "IMPROVEMENTS IN
AWWWCTED OF DADDY"
Scaled the 30th July 1869, and dated the 3rd April 1869.
PROVISIONAL SPECIFICATION left by the said Ramsay Allan at the
Office of the Commissioners of Patents, with his Petition, on the
3rd April 1869.
I, RAMSAY ALLAN, of Kelvindale, in the County of Lanark, North
Britain, do hereby declare the nature of the said Invention of "IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF PAPER," to be as follows,
that is to say :-
This Invention, which relates to improvements in machinery for the
manufacture of paper, consists in dispensing with the woollen or felt
jacket which is at present employed on the lower coutch roll of paper-
making machinery, and in using the upper couch roll only covered.
The rollers may act on the paper by means of the weight of the upper,
or they may be acted upon by weighted levers to obtain greater
pressure.
By means of this arrangement considerable economy is effected, whilst
at the same time an equal effect is produced upon the paper, and the

page_text: amount of pressure necessary is less than what is at present required
where both rolls are covered.
Another advantage resulting from this arrangement is that the endless
wire webs being subjected to less wear endure for a greater length of
time.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ramsay Allan in the Great Seal Patent Office
on the 1st October 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RAMSAY
ALLAN, of Kelvindale, in the County of Lanark, North Britain, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of April, in the year of our Lord
One thousand eight hundred and sixty-nine, in the thirty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Ramsay Allan, Her special license that I, the said
Ramsay Allan, my executors, administrators, and assigns, or such
others as I, the said Ramsay Allan, my executors, administrators, or
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 MACHINERY FOR THE MANUFACTURE
OF PAPER," upon the condition (amongst others) that I, the said Ramsay
Allan, by an instrument in writing under my hand and seal, 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 Ramsay Allan, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed to be particularly described and ascertained in and by the
following statement, that is to say :-
My said Invention, which relates to improvements in machinery for
the manufacture of paper, consists essentially in dispensing with the

page_text: woollen or felt jacket which is at present employed on the lower coutch
roll of paper-making machinery, thus using the upper coutch roll only
covered. The rolls or rollers are preferably ground together so as to
ensure a practically perfect contact or complete joint throughout their
length. The rolls or rollers may be caused to act on the paper passing
through them by means of the weight of the upper roll itself, or levers
and weights may be employed in combination therewith to obtain greater
pressure when necessary. These levers and weights when used may be
applied in any of the usual modes for producing pressure.
By means of this Invention considerable economy is effected in paper-
making machinery, as less woolen or felt material is required, whilst at
the same time a better effect is produced upon the paper, as it is rendered
drier and better adapted for passing on to the next stage of preparation.
The amount of pressure necessary is also considerably less than what is
required in paper-making machines where both the upper and lower
rolls are covered, and the jacket on the top roll is thus also rendered
more durable than when both rolls are covered.
Other advantages resulting from this Invention are that the endless
wire webs employed in paper-making machinery require no washing
except on the edges, and they endure for a longer time as they are sub-
jected to less wear and tear than under the existing arrangement of such
portions of paper-making machinery.
Having now described the nature of my said Invention, and the
mode or manner in or under which the same may be carried into
effect, I would observe in conclusion that what I consider novel and
original, and therefore claim as the Invention secured to me by the
herein-before in part recited Letters Patent is, the dispensing with the
woolen or felt jacket of the lower coutch rolls of paper-making
machinery, whereby economy is effected and other advantages secured
as herein-before described.
In witness whereof, I, the said Ramsay Allan, have hereunto
set my hand and seal, this Thirtieth day of September One
thousand eight hundred and sixty-nine.
