Norwich, for the Invention of "IMPROVEMENTS IN DAMPING PAPER FOR
PRINTING."
Sealed the 20th January 1857, and dated the 18th November 1856.
PROVISIONAL SPECIFICATION left by the said Frederick Arthur Magnay
at the Office of the Commissioners of Patents, with his Petition, on the
18th November 1856.
I, FREDERICK ARTHUR MAGNAY, of Taverham Mills, Norwich, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN DAMPING PAPER FOR
PRINTING," to be as follows:-
On the Seventeenth day of October last Provisional Protection was granted
to myself and Ralph Radcliffe Whitehead for improvements in damping paper
for printing; according to one part of which Invention the paper is fed a suit-
able number of sheets at a time on to an endless apron of felt, kept moist by
running through a trough of water, and this endless apron carries the paper
under a pressing roller, and then delivers it on to a receiving table. Now,
this Invention consists in adding to this machine two perforated pipes or other
suitable apparatus for throwing jets of water on to the upper and under
surfaces of the paper before it passes under the pressing roller.

and Ireland, the Channel Islands, and Isle of Man, an Invention for "IR-
PROVEMENTS IN DAMPING PAPER FOR PRINTING," upon the condition (amongst
others) that I, the said Frederick Arthur Magnay, 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, tho said Frederick Arthur Magnay, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
.
In tho Provisional Specification to a Patent, dated the Seventeenth day of
October last, and granted to myself and Ralph Radcliffe Whitehead for
improvements in damping paper for printing, there was described an Invention
whereby paper was to be damped by being carried on an endless wet felt,
and pressed between rollers. Now, this Invention consists in adding to this
machine two perforated pipes or other suitable apparatus for throwing jets of
water on to the upper and under surfaces of the paper before it passes under
the pressing roller.
Having thus stated the nature of my Invention, I will proceed more fully to
describe the manner of performing the same.

Figure 1 shows a longitudinal section of a machine constructed and combined
according to the said former Patent, together with my present improvements
thereon; Figuro 2 shows a plan of such machine. The letters of reference of
these Figures correspond with those used in our previous Specification; and my
present improvements consist in the application of the tubes H, I, or other
similar apparatus for supplying jets or streams of water to the under and
upper surfaces of the paper before the same passes between the pressing
rollers C and B, by which the paper will be more quickly and uniformly
damped.
In witness whereof, I, the said Frederick Arthur Magnay, have here-
unto set my hand and seal, this Fourth day of May, in the year of
our Lord One thousand eight hundred and fifty-seven.
