Year: 1858

page_text: LETTERS PATENT to William Wildes, of Maidstone, in the County of
Kent, Paper Maker, for the Invention of "AN IMPROVED ARRANGEMENT
OR ARRANGEMENTS OF MACHINERY FOR REDUCING VEGETABLE MATTER TO
PULP"
Sealed the 14th January 1859, and dated the 17th July 1858.
PROVISIONAL SPECIFICATION left by the said William Wildes at the
Office of the Commissioners of Patents, with his Petition, on the 17th
July 1858.
I, WILLIAM WILDES, of Maidstone, in the County of Kent, Paper Maker,
5 do hereby declare the nature of the said Invention for "AN IMPROVED ARRANGE-
MENT OR ARRANGEMENTS OF MACHINERY FOR REDUCING VEGETABLE MATTER TO.
PULP," to be as follows:-
My Invention consists in driving rolls or cylinders, through which the
vegetable matter is passed to be converted into pulp, at different speeds; or in
employing rolls or cylinders of unequal diameters, and driving them at the
same speed.

by the said William Wildes in the Great Seal Patent Office on the
17th January 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WILDES, of Maidstone, in the County of Kent, Paper Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of July, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Wildes, Her special licence that I, the said William Wildes,
my executors, administrators, and assigns, or such others as I, the said
William Wildes, 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 "AN IMPROVED
ARRANGEMENT OR ARRANGEMENTS OF MACHINERY FOR REDUCING VEGETABLE MATTER
TO PULP," upon the condition (amongst others) that I, the said William Willes, my
executors or administrators, 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 Willes, 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 driving rolls or cylinders, through which the
vegetable matter is passed to be converted into pulp, at different speeds; or in
employing rolls or cylinders of unequal diameters, and driving them at the.
same speed, whereby a crushing and rubbing action will be exerted upon the
fibres.
In order that my Invention may be fully understood, I proceed to describe
the machine shewn in the accompanying Drawings.
Figure 1 is an end elevation, and Figure 2 a side view, of a pulping
machine composed of five rolls of about equal diameter, but driven at different

page_text: speeds. An additional rubbing effect is produced in the machine shewn in
the Drawings, by two of the rolls having a to-and-fro motion as well as rotary
motion imparted to them, but this to-and-fro motion is not necessary, and
may, if desired, be dispensed with. A, A, is the frame carrying bearings for
the rolls B, B', B2, B3, and B'; C, C, are cam-shaped collars on the axes of
the rolls B¹ and B³, which rotating in the clutches D, D, bolted to the side
frame, cause the rolls B¹ and B³ to travel while rotating in a direction to and
fro across the machine; E is the main driving shaft, carrying fast and loose
pullies F-G, the fly wheel H, and also the roll B. Motion is communicated
to the rest of the rolls through the gear wheels and pinions I on their axes;
these gear wheels and pinions are so arranged as to diameter with respect to
each other, that no two of the rolls in contact with each other shall move at
the same surface speed; I do not limit myself to any particular number of
rolls, as more or less may be used according to the nature of the vegetable
matter acted upon.
I have not thought it necessary to give a Drawing of an arrangement of
rolls of different diameters driven at the same speed, as the construction of
such a machine will be well understood by any engineer used to the con-
struction of rolling mills.
And having now described the nature of my said Invention, and in what
manner the same may be performed, I declare that I claim the arranging of
rolls or cylinders in a machine for reducing vegetable matter to pulp, in such
manner as to exert a simultaneous rubbing and crushing action upon the
matter to be pulped.
In witness whereof, I, the said William Wildes, have hereunto set my
hand and seal, this Fourteenth day of January, One thousand eight
hundred and fifty-nine:
WILLIAM WILDES. (L.S.)
