Improvements in and relating to Ploughs.
I, FRIEDRICH BARTELS of Hoheneggelsen, in the German Empire, Manu-
facturer, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly docerihod and ascertained in and by
the following statement :-
This invention relates to ploughs and more especially to those for deep ploughing,
though it is also applicable to those employed for shallow ploughing. Its object is
to construct the plough in such a form that it can be drawn with a much reduced
expenditure of power.
A plough so constructed is formed without the usual sole which is substituted by
a pair of vertical wheels and a horizontal disc or wheel as shewn in the accompany-
ing drawings reference to which is hereinafter made.
Figure 1 illustrates the improved plough in elevation;
Figure 2 shows it is plan;
Figure 3 represents a back view of the plough; and
Figure 4 is an elevation of a vertical section through the centre of the horizontal
dise so as to shew its inner construction.
As shown in the drawings e is the plough-beam, d the plough-share, and the
fore-cutter or colter. A second fore-cutter ar citer can be applied, for which
purpose the beam of the plough is provided with a suitable opening or hole
into which this second fore-cutter or colter may be inserted and fixed for temporary
use by means of wedges.
The vertical wheels a are mounted upon the common axis h carried by the
adjustable bracket or pedestal i secured to the plough frame or beam. The bearing
or support of the horizontal dise is arranged in such a way that the earth thrown
up and turned by the plough-share cannot get between the friction surfaces of the
metal. Its construction is as follows-(see Figure 4).
The supporting rod or pillar is secured at its upper end to the plough beam
and its lower end carries the fixed collar or dise upon which the whole weight of
the cylindrical dise rests. The disc is made of wood and is covered on both sides
with iron plates ma and on its periphery with an iron ring o. By means of the
disc p which is secured to the sleeve and is connected by screws to the disc b, the
bearing betweeen shaft and the sleeve is secured from immediate contact with
the earth or mould turned over by the plough.
To ensure also that no foreign substances can enter at the upper end of the
sleeve this is covered by a cap hung over the ring or collars. It has been
proved by tests and experiments that the employment of a plough constructed as
hereinbefore described will effect a saving of about two fifths of the draught
power which is necessary with ploughs of ordinary construction under exactly the
same conditions.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The combination with a plough of a pair of vertical wheels and a horizontal
wheel constructed and arranged substantially as hereinbefore described and as
Almed by the noi dearvings

page_text: 2. The combination with a plough of a horizontal dise or wheel constructed and
arranged substantially as hereinbefore described and as illustrated by the
accompanying drawings.
