PROVISIONAL SPECIFICATION left by the said William Weatherley at
the Office of the Commissioners of Patents, with his Petition, on the
8th April 1865.
I, WILLIAM WEATHERLEY, of Chartham, in the County of Kent, Paper
Manufacturer, do hereby declare the nature of the said Invention for "Iм-
PROVEMENTS IN SIZING PAPER, AND IN THE MACHINERY EMPLOYED THEREIN," to be
as follows:-
My Invention consists in performing the operation of sizing paper partly by
applying the size on one side of the paper previous to immersion in the usual
sizing trough, and partly by relieving the paper when soaked with size of all
strain or pull, and for these purposes I employ a roller supplied with size,
over or under which roller the paper passes before entering the usual size trough.

by the said William Weatherley in the Great Seal Patent Office on the
7th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WEATHERLEY, of Chartbam, in the County of Kent, Paper Manufacturer, send
greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of April, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Weatherley, Her special licence that I, the said William
Weatherley, my executors, administrators, and assigns, or such others as I, the
said William Weatherley, my exccutors, administrators, and assigns, should at
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 "IMPROVEMENTS IN
SIZING PAPER, AND IN THE MACHINERY EMPLOYED THEREIN," upon the condition
(amongst others) that I, the said William Weatherley, my executors or admi-
nistrators, 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 William Weatherley, 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say:-
My Invention consists in performing the operation of sizing paper partly by
applying the size on one side of the paper previous to immersion in the usual
sizing trough, and partly by relieving the paper when soaked with size of all
strain or pull, and for these purposes I employ a roller supplied with size, over
or under which roller the paper passes before entering the usual sizing
trough.
The Invention will be fully understood on reference to the accompanying
Drawings, and the following description thereof.

page_text: Figure 1 is a side view, and Figure 2 a plan of a machine for sizing paper
constructed according to my Invention..
a, a', are two rollers connected to a bar b, which is supported by standards
on the frame; c is a roller, which I term the first sizing roller, it revolves in
bearings on the frame, and is driven by band gearing; d, d', are arms centred
at e to a cross bar f. Each of these armis has connected to it two small
rods g, g', attached to bell-crank levers h, h¹, the outer ends of which levers
carry a roller i for the purpose hereafter stated. The bar f has other arms
k, k, keyed to it, between which a second sizing roller is free to revolve.
On the outer ends of the arms d, d₁, are pinions furnished with handles to
allow of their being turned. The spindle on which the pinions are mounted
is weighted to counterbalance the weight of the roller l. The pinions gear
into racks m fixed to the side frames. A bolt n passes through the arm d
into the side frame for the purpose of securing the roller in any desired
position. The shaft p of the roller rests upon supports when it is in the
trough. The arms k, k', also carry a roller r, under which the paper is made
to pass as hereafter described. The band which drives the roller / passes
round small weighted wheels, the weights are free to slide up and down a
vertical bar to allow of the slack being taken up when the roller is lifted out
of the size trough. The action is as follows:-Paper when first brought from
the drying cylinders is passed over the roller a, under the central rod b and
roller a over the roller i, through between the roller and transverse bar f
into and between the press rolls s, t, to the reels as represented by the dotted
lines. The pinions are then raised with the arms d, d', the action of the
short rods g, g', and bell-crank levers h, h, brings down the roller i clear of
the paper, and the roller is immersed in the size carrying the paper with it;
the tension thus put upon the paper causes the rollers a, a', to turn upon their
central bar b, whereby the paper is brought down upon the roller c, and
becomes sized upon its under surface, owing to the roller c revolving partly in
the size trough; this sizing of one side of the paper moistens it, drives out the
air, and renders it more fit to be submitted to the ordinary sizing by being
passed under the roller as represented by the full lines. The roller c is driven
at a greater speed than the roller to relieve the soaked portion of the paper
from strain or pull, and to ensure a sufficient supply of size to the under
surface of the paper before entering the trough. The roller a' is weighted
according to the thickness and quality of the paper to be sized.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-

page_text: First, sizing paper by applying the size on one side thereof previous to
immersion in the usual sizing trough.
Second, constructing machinery for sizing paper, and for relieving it when
soaked with size of all strain or pull, substantially as herein-before described
and represented in the accompanying Drawings.
In witness, whereof, I, the said William Weatherly, have hereunto set
my hand and seal, this Sixth day of October One thousand eight hun-
dred and sixty-five.
W. WEATHERLEY. (L.S.)
