COMPLETE SPECIFICATION.
An Improved Plough.
I, OSCAR MARSH, of 39 Chaussestrasse, Berlin, German Empire, Director, do
hereby declare the nature of this invention 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 a plough, saving considerable power and effecting the
even distribution or deposition of the soil which has been ploughed up; for which
purposes the plough is provided with adjustable dished plates or shovels behind the
shares of the plough so as to take up the soil fed by the shares and to turn and
disintegrate the same, afterwards placing it in the open furrows.
In the accompanying drawings I illustrate a plough constructed according to my
invention.
Figure 1 is a side elevation,
Figure 2 is a plan, and
Figure 3 is a back view of the same.
In this case my invention has been applied to a plough having two shares, but it
may also be used for ploughs having one or any number of shares.
The plough, as shown, consists of a frame e, having an axle 6 on which is situated
an adjustable pair of wheels a, a roller k with pin l, and a lever c for adjusting the
pair of wheels a. Besides the foregoing parts, the frame e is provided with the
shares f. The pair of wheels a are adjusted by the lever c, so that the wrought
iron frame e and the shares fare lowered according to the depth to which the soil
is to be worked. The frame e is further provided with the sleeves i situated
obliquely to the frame and forming the bearings for the pivots of dished plates or
disintegrating wheels h. One of these dished plates is provided behind each share.
These dished plates are provided with ribs in by means of which they are rotated
through making contact with the ground when the plough is propelled; at the
same time these ribs serve to disintegrate the soil fed from the shares. If desired,
shovels may be used instead of the dished plates.
When the roller k (used for transporting the plough) has been taken off, after
removing the pin l, and the shares have been adjusted to the desired height, the
plough is propelled forwards. The shares fcut the soil at right angles, and push it
towards the dished plates h where the soil is disintegrated, turned over, and thrown
sidewards into the open furrow.
By the above described arrangement of the rotary dished plates little power is
required to place the soil into the open furrow in the most suitable manner, as the
soil is thus fed systematically by the rotation of the dished plates h, the force
exerted having only to overcome the slight friction between the sleeves i and the
pivots of the plates h.
These ploughs may be adapted to any soil or ground, and though they may be
used very advantageously for ploughing the soil at less or greater depth, the
advantages are particularly apparent in the latter case.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A rotary plough characterised by the arrangement behind the share or shares of
one or more adjustable dished plates with ribs or shovels which take un the soil

the purposes of saving power and effecting an even distribution of soil thrown up,
substantially as described and illustrated.
