page_text: I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex do hereby declare the nature of this invention (a communication to
me from abroad by Charles Alcide Collin, of Vendeuvre, in the Republic of
France, Engineer) to be as follows :—
This invention relates principally to the construction of the fore-carriages of
ploughs, and it has for its objects novel arrangements for the purpose of adjusting
and regulating the position of the different parts of the implement whilst it is in
operation.
The improved fore-carriage consists first, of apparatus for regulating the depth of
the furrows made by the plough; second, of apparatus for inclining the plough to
the right or left more or less according to the variation of the ground passed over;
and third, of apparatus for moving more or less to the right or left the point of
traction of the plough.
The apparatus for regulating the depth of the furrow consists of a horizontal
forked bar into which fits the beam of the plough which is held in position by side
plates or stays bolted to the upper and lower arms of the fork. The front end of
the bar is cylindrical and is pivotted into a crossbar in which it is retained by a
pin, and this crossbar is connected by two rods to a transverse screwed nut above,
through which fits a vertical screw having at its upper end a handle by which it
can be turned, the screw being carried by a socket in a vertical frame fixed to the
carriage.
By turning the handle in one or other direction, therefore, the forked bar and
the beam of the plough are raised or lowered, as well as the plough itself and the
depth of the furrows is thus determined.
The apparatus for inclining the plough to the right or left, according to the
character of the ground passed over, consists of a horizontal bolt sliding in strong
guides fixed to the side of the forked bar already described, and pressed forward
by a spring so that its point enters a notch or hole in the centre of a sector or
segment shaped plate arranged opposite to it. This sector is jointed on one side to
the cylindrical part of the forked bar first described, and on the other side to a nut
TD 0.71

page_text: which fits upon a vertical screwed rod turning in fixed bearings and provided at
its upper end with a handle. When, therefore, the configuration of the ground
renders it desirable to incline the plough to one side or the other, the screw
described is turned by the handle so that the nut is raised or lowered and carries
with it the sector round the cylindrical forked bar.
The point of the sliding bolt carried on the forked bar being engaged in the
notch or hole in the sector, the bolt together with the forked bar and the beam of
the plough, are moved simultaneously to the right or left.
Similar apparatus to that last described may be arranged upon the opposite side
of the plough, so that the carriage being arranged to receive what is known as the
"Brabant turn wrest" plough, the handle on the right side serves for regulating
the inclination when ploughing on the left side, and vice verâ. In order to make
the necessary alternate changes, a rod is pulled which is attached to the sliding
bolt so as to compress the spring and withdraw the point of the bolt from the
sector. The plough can then be turned over to operate in the opposite direction,
and the sliding bolt being released the spring forces it into and connects it with
the opposite sector.
The device for adjusting the point of traction of the plough consists of a draw
bar or hook jointed to the frame of the carriage. The front of the bar is attached
to a nut which can slide transversely in guides without turning, and a transverse
screw passes through it the ends of which are carried in bearings, a handle being
provided by which it can be turned so as to make the nut and bar traverse to the
right or left.
The beam of the plough is connected to the fore-carriage by a rod attached at
its front end to the axis of the draw bar or hook, under the frame of the carriage.
In ploughing hillsides, in order to prevent the risk of the carriage overturning
the wheels are provided each with a separate axle sliding in a hollow sleeve or
frame forming part of the carriage, so that the wheels may separate to a greater
distance apart when desired.
In this way, the carriage is less liable to overturn, either in the case already
mentioned or of too sharp a turn. A pin or bolt is arranged by which the axles
are held and the wheels prevented from separating or closing together when the
plough is doing its ordinary work.
In order to facilitate the moving of the plough, and to allow it to work more
readily in curves of short radius the frame is jointed at the centre upon a vertical
joint and has lateral arms with concentric grooves in which are fitted the supports
of a frame which carries the cross bar in which the cylindrical part of the forked
bar fits as first described.

page_text: I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex do hereby declare the nature of this invention (a communication
from Charles Alcide Collin, of Vendeuvre, in the Republic of France, Engineer),
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, and accompanying drawing, (that is
to say):
This invention relates more especially to the construction of the forecarriages of
ploughs, and it has for its objects novel arrangements and methods of construction
for the purpose of adjusting and regulating the position of the different parts of thé
implement whilst it is in operation.
The improvements in the forecarriage consist first of apparatus for regulating the
depth of the furrows made by the plough; second, of apparatus for inclining the
plough to the right or left more or less according to the variations of the ground
passed over, and third, of apparatus for moving more or less to the right or left the
point of traction of the plough.
In the accompanying drawing which is in illustration of the invention, Figure 1
is a side view of the front of the plough, and figure 2 is a vertical section through
the line 1, 2, in figure 1.
The apparatus for regulating the depth of a furrow consists of a horizontal
forked bar A into which fits the beam B of the plough which is held in position
by side plates or stays C C bolted to the upper and lower arms of the fork.
The front end of the bar at D is cylindrical and is pivotted into a crossbar E in
which it is retained by a pin and this crossbar is connected by two rods a a to a
transverse screwed nut b through which fits a vertical screw G having at its upper
end a handle H by which it can be turned the screw being carried by a socket in a
vertical frame fixed to the carriage. By turning the handle H in one or other
direction therefore the forked bar A and the beam of the plough are raised or
lowered and the depth of the furrows is thus determined. The apparatus for
inclining the plough to the right or left according to the nature of the ground
which is being ploughed consists of a horizontal bolt or pin I sliding in strong
guides J fixed to the side of the forked bar A and pressed forward by a spring so
that its point enters a notch or hole d in the centre of a sector or segment shaped
plate Karranged opposite to it. This sector is jointed on one side to the cylindrical
part of the forked bar A and on the other side to a nut Li which fits upon a vertical
screwed rod M turning in fixed bearings and provided at its upper end with a
handle N. When therefore the configuration of the ground renders it desirable to
incline the plough to one side or the other, the screw M is turned by the handle N
so that the nut L is raised or lowered and carries with it the sector K round the
cylindrical part of the forked bar A.
The point of the sliding bolt I being engaged in the notch or hole in the sector K
the bolt I together with the bar and the beam B of the plough are moved simul-
taneously to the right or left,

page_text: Similar apparatus to that last described is shewn arranged upon the opposite
side of the plough, so that the carriage being arranged to receive what is known
as the "Brabant" turn-wrest plough the handle N on the right side serves for
regulating the inclination when ploughing on the left side and vice versa.
In order to make the necessary alternate changes a rod O is pulled which is
attached to the sliding bolt I so as to compress the spring and withdraw the point
of the bolt from the sector. The plough can then be turned over to operate in the
opposite direction and the sliding bolt I being then released the spring forces it
into and connects it with the opposite sector.
The device for adjusting the point of traction of the plough to the right or left
as desired consists of a drawbar o jointed to the frame P of the carriage. The
front of this bar o is attached to a nut which can slide transversely in guides Q
without turning and a transverse screw passes through it which turns in bearings S
carried by the frame P of the carriage, a handle T being provided by which the
screw can be turned so as to cause the nut and bar o to traverse to the right or
left. The beam of the plough is connected to the forecarriage by a rod U attached
at its front end to the axis of the drawbar or hook under the frame of the
carriage.
In ploughing hill sidos, in order to prevent the risk of the carriage overturning
the wheels are provided each with a separate axle sliding in a hollow sleeve or
frame forming part of the frame P of the carriage so that they may be separated
to a greater distance apart when desired.
In this way the carriage is less liable to overturn either in the case already
mentioned or. of too sharp turns.
A pin or bolt is provided at the centre of the frame by which the axles are held,
which can be passed through the axles and prevents the wheels from separating or
closing together when the plough is doing its ordinary work.
In order to facilitate the moving of the plough and to allow it to work more
readily in curves of short radius the frame P is jointed at the centre X and has
lateral arms with concentric grooves in which are fitted the supports of a frame
which carries the crossbar E in which the cylindrical part of the forked bar A fits
as first described.
Figure 3 shews a rod all fixed to the guide J at one end the other end carrying
a lever a¹ and handle jointed to the rod O so that the ploughman can more
readily draw back the bolt I when required as above described.
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 method of and apparatus for raising or lowering the plough substantially
as described and shown.
2. The method of and apparatus for inclining the plough to the right or left
substantially as described and shewn.
3. The method of and apparatus for altering the position of the point of traction
substantially as described and shewn.
4. The general arrangement and combination of the several parts substantially
as described and shewn.
