Year: 1869

page_text: LETTERS PATENT to Florent Joseph Vandenvinne, of Brussels, in the
Kingdom of Belgium, for the Invention of "IMPROVEMENTS IN AP-
PARATUS FOR WORKING PLOUGHS FOR CLEARING OR GRUBBING UP UNCUL-
TIVATED LAND."
PROVISIONAL SPECIFICATION left by the said Florent Joseph Van-
denvinne at the Office of the Commissioners of Patents, with his
Petition, on the 12th February 1869.
"I-
I, FLORENT JOSEPH VANDENVINNE, of Brussels, in the Kingdom of
Belgium, do hereby declare the nature of the said Invention for "
PROVEMENTS IN APPARATUS FOR WORKING PLOUGHS FOR CLEARING OR GRUBBING
UP UNCULTIVATED LAND," to be as follows:-
This improvement in the mode and application for working my In-
vention, patented 28 May 1867, No. 1573, for "An Improved Machine or
Plough for Clearing or Grubbing up Uncultivated Land," consists in an
endless railway so attached to the machine that the wheels rest thereon,
and the railway is by suitable gearing and proper articulated joints

page_text: made to revolve round the said wheels so as to prevent the wheels
through the great weight of the machine from being imbedded in the
earth or impeded by stones or other matter. The said railway can be
made of wood, metal, or any other suitable material.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Florent Joseph Vandenvinne in the Great Seal
Patent Office on the 12th August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FLORENT
JOSEPH VANDENVINNE, of Brussels, in the Kingdom of Belgium, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of February, 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 suc-
cessors, give and grant unto me, the said Florent Joseph Vanden-
vinne, Her special licence that I, the said Florent Joseph Vandenvinne,
my executors, administrators, and assigns, or such others as I, the said
Florent Joseph Vandenvinne, 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 APPARATUS FOR WORKING PLOUGHS FOR
CLEARING OR GRUBBING UP UNCULTIVATED LAND," upon the condition (amongst
others) that I, the said Florent Joseph Vandenvinne, my executors
or administrators, by an instrument in writing under my, or their, or one
of their hands and scals, 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 Scal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.
.
NOW KNOW YE, that I, the said Florent Joseph Vandenvinne, 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 :-

page_text: The improvements in the mode of working my
"Machine or Plough
for Clearing or Grubbing up Uncultivated Land," for which I obtained
Her Majesty's Letters Patent, dated the 28th day of May 1867, No. 1578,
consist in an endless railway, so attached to the machine that the
wheels rest thereon, and the railway, by the motion of the machine
forward or backward and suitable articulated joints therein, is caused to
be laid continuously under the wheels so as to prevent them through the
great weight of the machine from being imbedded in the earth or .
impeded by stones or other matter. The said railway can be made of
wood, metal, or any other suitable material.
In order to make the Invention more readily and fully understood
I will now give a complete description of it, referring to the annexed
Drawing, and to the Figures and letters marked thereon.
A, A, A, A, represents the articulated endless railway, on the lower
part of which rest the wheels Z' of the machine, the upper part being
supported and moving on suitable rollers B,B, B, fitted in frames C,C,C,O,
attached to the machine above and partially around the wheels Zt, so
that on a forward or backward movement being given to the machinery
the endless railway is caused thereby to lay itself continuously on the
ground under the wheels Z', Z, Z', Z'.
.
Having now described and particularly ascertained the nature of my
Invention, and the manner in which the same may be put into effect, I
wish it to be understood that I do not intend to restrict or limit myself
to the precise details of the apparatus above described and illustrated
in the annexed Drawing; but what I consider novel and original is,
adapting the endless railway to my above-mentioned plough, and for the
purposes described.
In witness whereof, I, the said Florent Joseph Vandenvinne, have
hereunto set my hand and seal, this Twelfth day of August, in
the year of our Lord One thousand eight hundred and sixty-nine.
Witness,
GEO. WHITE.
