AN IMPROVED PLOUGH
Year: 1873

page_text: LETTERS PATENT to Victor Chambon, of Toulon, Department of the
Var, in the Republic of France, Gentleman, for the Invention of
"AN IMPROVED PLOUGH."
PROVISIONAL SPECIFICATION left by the said Victor Chambon at the
Office of the Commissioners of Patents, with his Petition, on the
1st December 1873.
I, VICTOR CHAMBON, of Toulon, Department of the Var, in the
Republic of France, Gentleman, do hereby declare the nature of the
said Invention for "AN IMPROVED PLOUGH," to be as follows:-
On reference to the accompanying Sheet of Drawing forming part of
my Provisional Specification, it will be seen that the body of my
improved plough is composed of an iron frame A, upon the upper part
of which are supported four grooved or rim pulleys D of optional
diameter, their bearings being bolted on the frame. The longitudinal
cross bars of the frame extend beyond the back of the frame, bending
downward, and receive' on the quadrant that they describe the blades or

page_text: shares B which are bolted upon these extensions pierced with three
holes for that purpose.
According to the kind of work to be performed by my pulley plough,
the arched part of the bars N or longitudinal cross bars of the frame A
will be fitted with spare shares of optional and various size, and which
may be set vertically or horizontally. These blades or shares B are tied
to the frame A, and supported in their respective position by cross
bars K of round or square iron, No. 1, screwed at the lower end upon the
shares, the upper end being bolted upon the frame A. Knives or
coulters C are also fastened and bolted to the under side of the frame,
each one in front of a share; these knives are intended to prepare the
work for the shares B by dividing the soil.
Iron pickets or stakes F having at the top a grooved pulley D" of the
same diameter as those D and D¹ of the main body of the plough are set
upon a cross bar H, upon which they are secured by the stays or
catches G. The cross bar H is laid on the ground at one end of the
field or piece of ground to be ploughed or sown, the pickets F keeping it
in the place where it has been set, while serving at the same time for the
traction of the plough. These pickets may be of any required length,
and be sunk more or less into the ground according to the work to be
done. The ropes I which lie in the grooves of the pulley D' of the body
of the plough are secured by a knot upon the pickets F in the grooved
part below the pulley case or bearing in the upper part of these pickets.
The ropes E received in the groove of the pulley D also pass into the
groove of the pulleys D" of the pickets F, in such a way that the part E¹
of these ropes E being attached to the yoke of oxen or team of horses
(according to the work to be done and the nature of the soil), and the
rest of the ropes E circulating in the groove of the pulleys D", the yoke
or team will by the aid of the pickets F effect the traction of the
plough.
If the extent of the ground will not permit the removal of the pickets,
the yoke or team will be made to move backwards, so as when arrived at
the point of departure to begin again as at first.
The main body of my plough may undergo numerous modifications as
well to suit the work to be done as the kind of ground upon which it is
to be executed and the nature of the climate in which the soil is situated.
For example, my system of pulley plough may be used as well for the
"

page_text: plantation of the vine as for sowing corn or any other grain or seed,
subject to suitable modifications in each of these cases.
With my pulley plough the ploughing and the sowing of any ground.
may be effected at one operation by simply adapting to the hind.
carriage J a drill or a harrow, or any other implement according to the
complex work it is desired to perform.
For the steppes or great plains, such for instance as those of Africa,
the main body or frame A of my plough will be of much larger
dimensions, especially in its breadth, and the number of the shares
should be doubled or even further increased if required. In this case
two or three beasts should be yoked abreast, and it is almost needless to
observe that oxen, horses, mules, or other draught animals may be
emploved.

Letters Patent, bearing date the First day of December, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Victor Chambon, Her special
licence, that I, the said Victor Chambon, my executors, administrators,
and assigns, or such others as I, the said Victor Chambon, my
exccutors, 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
PLOUGH," upon the condition (amongst others) that I, the said Victor
Chambon, 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 Victor Chambon, 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 :-
On reference to the accompanying Sheet of Drawing forming part of
this Specification it will be seen that the body of my improved plough is
composed of an iron frame A, upon the upper part of which are sup-
ported four grooved or rim pulleys D of optional diameter, and with
their bearings bolted on the frame. The longitudinal cross bars of the
frame extend beyond the back of the frame, bending downward, and
I receive on the quadrant that they describe the blades or shares B which
are bolted upon these extensions pierced with three holes for the
purpose.
According to the kind of work to be performed by my pulley plough,
the arched or curved part of the bars N or longitudinal cross bars of the
frame A will be fitted with spare shares of optional and various size, and
which may be set vertically or horizontally. These blades or shares B
are tied to the frame A, and supported in their respective position by

The novelty of my improved plough consists in the general com-
bination of its parts, and more particularly in the combination of the
traction gearing composed of ropes, pulleys, and pickets, substantially as
above set forth.
In witness whereof, I, the said Victor Chambon, have hereunto set
my hand and seal, this Twenty-fifth day of May, in the year
of our Lord One thousand eight hundred and seventy-four.
