I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents, and
Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows;
-
This invention relates to ploughs electrically driven and moved and it differs
from the devices hitherto employed for the like purposes by the substitution for
ploughshares of a number of rotating conical screws which may be raised or
lowered according to the desired depth of the furrows. The rotating movement
of these screws, as well as the forward and backward movement of the plough
carriage are effected by means of a single electro motor, of suitable kind.
the boring action of the screws, which are used instead of ploughshares, is calcu-
lated to assist the forward movement of the carriage and the removal of the
ploughed soil, a considerable amount of power is saved by employing such screws
instead of the ploughshares hitherto ordinarily used.
As
The framing which carries the electrical motor with its reversing gear, the
plough apparatus, and the steering apparatus, rests upon three wheels, the fore-
most one of which serves as a guide wheel and is carried in a fork at the lower
end of a vertical guide shaft. On this guide shaft is fixed at the upper end a
bevelled tooth wheel which gears with another similar wheel moved by a hand
wheel so that by turning the latter in one or the other direction the plough carriage
may be steered or guided.
The motor drives by means of a suitable spur gear a horizontal shaft which
effects the backward and forward movement of the carriage, and also actuates the
rotating screws. The former motion is transmitted by means of a belt gearing
which actuates the hind wheels of the carriage; the latter also by means of belt-
gearing.
The forward and backward movement of the carriage is effected by means of
a simple reversible wheel gear, such for instance as a double bevelled wheel gear-
ing which can be reversed in the usual way by means of a reversing lever.
Or the changing of the forward and backward movement of the carriage may
be effected by reversing the electro-motor itself. The ploughing screws are
arranged with their shafts alternately, and in such a manner as to be prevented
from moving endways in their bearings in frames which are suspended behind
each other on transverse shafts, being driven by the belt gearing already referred
to, and the screw shafts themselves are driven by pairs of bevelled toothed wheels
upon the transverse shafts, and upon the upper end of the ploughing screw shafts
respectively. This mode of gearing has for its special purpose that the axes of
the screw shafts may be more or less inclined as may be needed for obtaining the
required depth of the furrows without detriment to the steady driving of the
mechanism. The working of all the ploughing screws is effected simultaneously
and in a uniform manner by raising or lowering the frames which carry them.
In order to adjust and fix these frames to the desired position a vertical screw is
arranged in bearings on the frame of the plough carriage, so as to be prevented

screw is turned as required by means of a pair of bevelled wheels one of which
is fixed at the top of the screw, whilst the other is fixed upon the back end of a
horizontal shaft extending forward to the engine platform or footplate, the shaft
being actuated by means of a hand wheel.
The plough carriage is entirely protected by a roof or cover.
The electric current is conveyed to the motor by means of two rings acting as
sliding contacts at the top of the hollow vertical post fixed upon the roof and itself
covered in.
The said rings are insulated both from each other and from the post which
carries them and receive the current at their outer edge from bushes which are
fastened to a bracket which can turn round the post.
This arrangement has for its object that the current may be conveyed by con-
ducting wires to the motor while the plough is travelling round the field, with-
out being obliged to displace its source of electricity itself placed in the centre
of the field.
When the plough carriage is to be moved backwards, or when it is to be driven over
roads, the ploughing screws are raised by means of the apparatus already described,
so that they do not touch the ground. As has already been explained the boring
movement of the screws aids the forward movement of the carriage and facilitates
considerably the work of ploughing as compared with the ploughshares hitherto
employed.
With the improved plough, ploughing is begun at a corner of the field and is
continued by following spirally the edges of the same in parallel furrows until the
centre is reached, so that the plough carriage needs only to be guided at the
corners, while for the rest it may move regularly and continuously forward.

A Communication to me from The Firm of T. GANSEL, of Neusalz, a/d., 0., in the
Empire of Germany, Druggists.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, and accompanying drawings, that is to say:-
This invention relates to ploughs electrically driven and moved, and it differs
from the devices hitherto employed for the like purposes by the substitution for
ploughshares of a number of rotating conical screws which may be raised or
lowered according to the desired depth of the furrows. The rotating movement
of these screws; as well as the forward and backward movement of the plough
carriage are effected by means of a single electro motor, of suitable kind.
As the
boring action of the screws, which are used instead of ploughshares, is calculated
to assist the forward movement of the carriage and the removal of the ploughed
soil, a considerable amount of power is saved by employing such screws instead
of the ploughshares hitherto ordinarily used.

page_text: In the accompanying drawing, which is in illustration of the invention, Figure 1
is a horizontal section on the line - in Figure 2. Figure 2 is a vertical section
on the line y-y in Figure 1.
The framing A which carries the electric motor with its reversing gear, the
plough apparatus, and the steering apparatus, rests upon three wheels, the fore-
inost one a of which serves as a guide wheel and is carried in a fork al at the lower
end of the vertical guide shaft a². On this guide shaft is fixed at the upper end
a bevelled tooth wheel b which gears with another similar wheel 6 moved by a hand
wheel c, so that by turning the latter in one or the other direction the plough
carriage may be steered or guided.
The motor B drives by means of suitable toothed gear a horizontal shaft d
which effects the backward and forward movement of the carriage, and also
actuates the rotating screws. The former motion is transmitted by means of a
belt gearing C which actuates the hind wheels of the carriage, the latter also by
means of belt gearing D, D'.
The forward and backward movement of the carriage is effected by means of a
simple reversible wheel gear, such for instance as a double bevelled wheel gear-
ing, which can be reversed in the usual way by means of a reversing lever t.
Or, the changing of the backward and forward movement of the carriage may be
effected by reversing the electro-motor itself. The ploughing screws E, E¹, E³, E³,
are arranged with their shafts g, g', g², g, alternately, and in such a manner as
to be prevented from moving endways in their bearings in frames F, F¹, which
are suspended behind each other on transverse shafts e, f, which are driven by the
belt gearing D, D¹ already referred to. The screw shafts g, g', g³, g³ themselves
are driven by pairs of bevelled toothed wheels h upon the transverse shafts, one
of each pair being upon the shaft e or f and the other upon the upper end of the
ploughing screw shafts respectively. This mode of gearing has for its special
purpose that the axes of the screw shafts g may be more or less inclined as may
be needed for obtaining the required depth of the furrows without detriment to the
steady driving of the mechanism. The working of all the ploughing screws is
effected simultaneously and in uniform manner by raising or lowering the
frames F, F, which carry them, and which are connected together by pivotted
bars i.
In order to adjust and fix these frames to the desired position, a vertical screw k
is arranged in bearings on the frame of the plough carriage, so as to be prevented
from moving endways, and upon the screw travels a nut secured against turning
and coupled to the foremost frame F by a connecting bar or link m.
The screw k
is turned as required by means of a pair of bevelled toothed wheels n one of
which is fixed at the top of the screw, whilst the other is fixed upon the back
end of à horizontal shaft o extending forward to the engine platform or footplate,
the shaft being actuated by means of a hand wheel o¹.
The plough carriage is entirely protected by a roof or cover G.
The electric current is conveyed to the motor by means of two rings p, p, act-
ing as sliding contacts at the top of a hollow vertical post 9 fixed upon the roof G,
and itself covered by a cover q¹.
The said rings are insulated both from each other and from the post q which
carries them, and receives the current at their outer edge from sliding brushes r, r¹,
which are fastened to a brackets which can turn round the post q.
This arrangement has for its object that the current may be conveyed by con-
ducting wires to the motor while the plough is travelling round the field, without
being obliged to displace its source of electricity itself placed in the centre of the
field.
When the plough carriage is to be moved backwards, or when it is to be driven
over roads, the ploughing screws are raised by means of the apparatus already
described, so that they do not touch the ground. As has already been explained
the boring movement of the screws aids the forward movement of the carriage
and facilitates considerably the work of ploughing, as compared with the plough-
shares hitherto employed.

page_text: With the improved plough, ploughing is begun at a corner of the field and is
continued by following spirally the edges of the same in parallel furrows until
the centre is reached, so that the plough carriage needs only to be guided at the
corners, while for the rest it may move regularly and continuously forward.
