IMPROVEMENTS IN PLOUGHS
Year: 1884

page_text: I, CLAUDE JOSEPH VIRCONDELET of Jussey (Haute-Saône) in the Republic of
France, Shoeing-smith, do hereby declare the nature of my Invention for
"IMPROVEMENTS IN PLOUGHS" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This Invention relates to improvements in ploughs and has for its object to
increase the strength thereof without increase of weight and also to considerably
reduce the tractive power required for operating the same.
Referring to the accompanying Drawing which is a side elevation of a plough
constructed according to this Invention, A is an iron frame designed to considerably
increase the strength of the plough and formed in such a manner that its weight
is less than that of the ordinary beam. B is an iron bar fixed to the ordinary
wooden shaft C by means of a fork D integral with the said bar, which is
connected with frame A by means of the piece E hinged upon a strong pin F.
G is an iron rack terminating in a fork H by means of which it is fixed to the
frame A. I is a handle for operating the bar B. J is a lever oscillating at K
upon the bar B and serving to operate the rack G. L L are stilts made of iron or
wood and provided with handles at their upper extremities.
M is a stock the upper part of which is provided with a shoulder N serving to
fix the same to the frame A. O is a traction hook fixed upon the shoulder of the
said stock M.
O' is a projection of the frame A serving for the bridle of the plough.
P is the share of the plough. Q is the fork. R is a standard and S the mould
board. T is an arm carrying the movable colter U which is tightly held at the
lower extremity thereof.
T' is a cast iron piece fixed to the frame A and serving to hold by means of a
clamping screw the arm T that carries the colter. This cast iron piece is provided
with three perforations the two front ones serving to raise or lower the same upon
the frame A. The movable colter U is formed of a steel blade having two cutting
edges, the lower of which (V) serves to cut into wet or grassy soils, and the upper
edge V' being used for dry and stony soils.
By fixing the movable colter U in a suitable manner, in the field after the share
and the stock of the plough the same may be operated in all weathers.

As shewn on the Drawing, the plough is provided independently of the improved
movable colter with the ordinary colter X rendered also movable and which may
be required in some cases.
It is to be noted that I may vary the forms and dimensions of the different
parts of this plough without departing from the nature of my Invention.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
. I claim is,
1. The improved construction of plough substantially as described and
illustrated.
2. In a plough the improved movable colter formed of a steel blade with two
sharp edges substantially as heréinabove described the use of which enables the
plough to be employed in all weathers and in various kinds of soils.
Dated this 24th day of July 1884.
