IMPROVEMENTS IN PLOUGHS to be as follows:-
Year: 1884

page_text: †, EMIL SEIDEL, Engineer of 37 Weidenweg, Berlin O. Prussia, German Empire,
do hereby declare the nature of the said invention for "IMPROVEMENTS IN
PLOUGHS to be as follows:-
"
This invention relates to improvements in ploughs whereby the depth of the
furrow can be more readily altered, and the plough be more easily, lifted out of
the furrow than could be heretofore done.
In front a cranked axle is provided on the pillow or fore carriage of the plough.
One limb of this cranked axle carries a large wheel which runs on the sole of the
furrow, the other limb carries a segment-piece. On this segment an angle-piece is
adjustable which as it were completes the cranked axle and carries a smaller wheel
acting as the land wheel. It is obvious that both wheels may if desired be made
adjustable. By the adjustment of the relative positions of the two wheels the
furrow produced by the plough may be readily varied. The segment piece of the
land wheel is by means of a connecting rod connected with a hand-lever pivoted
on the plough beam.
For lateral guidance of the hand lever a segment is provided but no special
provision need be made to fix it in either of its two normal positions as in both
it is in the line of direct pull of the draught animal or animals. When the lever
is in such a position that its free end points forward the fore carriage is in proper
position for ploughing when the lever is thrown back the connecting rod acting
on the segment tends to depress the wheels so that the share or shares are lifted
clear of the furrow.
It will be obvious that this invention is equally applicable to ploughs with one
or with several shares.

I EMIL SEIDEL of 37 Weidenweg, Berlin do hereby declare the nature of this
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 whereby the depth of the
furrow can be more readily altered and the plough be more easily lifted out of the
furrow than could be heretofore done.
To this end a two shared plough for instance is constructed as follows: A
cranked axle is mounted in front of the plough bodies so as to be capable of
rotating horizontally and supported on the pillow of the plough. This axle carries
at one end the wheel which runs in the furrow on the other end there is the land-
wheel One limb of this axle consists of two parts adjustable with relation to one
another in such a manner that the relative position of the wheels is likewise
adjustable and the depth of the furrow is thus capable of being varied.
The said axle is moreover so connected with a lever arrangement that by simply
operating a hand lever the two wheels arrive in a deeper position (relatively to
the plough body) whereby the plough is raised out of the ground and then can
readily be turned The power of the draught animals is by reason of the peculiar
construction of the crank axle utilised for the purpose of considerably facilitating
this operation.
In the accompanying drawings fig: 1 is an elevation and fig: 2 the plan of a
plough with two shares and embodying this invention.
On the front part of the plough is provided a cranked axle A One limb carries
the larger wheel R¹ which runs in the sole of the furrow the other limb carries the
segmental piece S. This is provided with holes as shown in fig: 3 or with a slot
as shown in fig: 4 serving for the reception of the screw a whereby the part B of
this limb connected with S at i may be fixed the part B carrying the land wheel R².
It is obvious that the limb carrying the wheel running in the furrow might be
made in two parts.
According to the relative positions of the parts B and S the wheels R¹ and R²
also assume different positions with relation to one another and it is obvious that
this readily allows the depth of the furrow to be altered.
In Figure 1 both wheels R1 and R2 are, when the plough is in its working
position, at the same level. This position is one extreme of the motion of the
said wheels, their other extreine position which can be produced by the segment S
is indicated in dotted lines in Figure 1.
The last mentioned position would correspond to the greatest depth of furrow
which is obtainable by means of this device. It will thus be seen that by adjusting
the part B with relation to A the depth of furrow can be altered.
To erable the plough to be lifted out of the furrow the segmental piece S is
connected with the lever C fulcrumed at Z by a connecting rod D. The lever C
may slide along a curve or segmental guide L which however merely serves as a
lateral guide for it and not for fixing the same. In the position shown in full lines
the lever C bears against the stop K and in this position is further secured by the

page_text: pull of the draught animals and the arrangement of the wheels on the frame, so
that special fixing devices are unnecessary. Now for lifting the plough out of the
furrow it will suffice to pull the lever C back until the same bears against the nut
of the screw y. The lever in being thus moved will by means of the rod D carry
the segment S and axle A and the wheels with it. This position of the parts is
shown in dotted lines and indicted by the letters C¹ D' R₁"R." The lever is held
in this position also as the direction of the rod D passes through the fulcrum Z of
the lever a pull in the direction of the rod can consequently not cause displacement
of the lever.
Special devices for fixing or clamping the lever in its extreme positions (for
instance bolts, catches or pawls) are not required and the avoidance of these
parts considerably facilitates the use of these ploughs and consequently is very
advantageous.
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
First For regulating the depth of furrow made by ploughs with one or more
shares, a double cranked axle so mounted on the plough frame as to be capable of
rotation one limb whereof consists of two parts.
Second-In combination with the adjusting device above referred to a device
for raising the share out of the furrow this device consisting in a lever C and the
coupling rod D connected with the axle A the position of the lever C being deter-
mined in one position by the stop K in the other position by the direction of the
rod being such as to pass through the point in which the lever is fulcrumed.
