GUALE DETE DIMOLTTOAIION,
A Rotary Plough.
1, WASILI PICHNO of the corner house of Kusucznaja and Kosowajewskaja.
Street Kieff Russia Law Student, 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 refers to a plough in which the share has the form of dish on:
edge which ploughs while rolling in that it cuts into the soil with its knife shaped
edge and severs a strip of earth on one side. The earth strip thus cut off glides up-
along the front part of the hollow surface of the dish-shaped share or plough body
and will in the further rolling action of the latter be turned off laterally towards
the last made furrow and laid down, as the vertical plane of the plough body does
not coincide with the directions of the furrow but cuts it at an angle which can be
altered according to the desired degree of deviation of the earth strip.
The plough construction will be understood from the accompanying drawings;
Figure 1 being a side view of the plough, Figure 2 a plan and Figure 3 a vertical
section. Figure 4 is a vertical section through the plough body or share drawn to
a larger scale.
The beam a is fixed under the wheel axle which carries the two wheels and c...
To the beam a is fixed by means of two screw bolts e and a plate y which carries.
bearings for the shaft of the disc forming the plough share. The bolt e passes
through round holes in the beam a and plate while the bolt passes through a
circular slot in the beam a struck from the centre of e.. When the nuts of the two
bolts have been loosened the plate g may consequently be turned around the bolt e-
as fulcrum, the shaft k of the share partaking in such movement and the share
thus obtaining any required angle to the furrow direction that the available
draught power will admit. The share is rigidly connected to the shaft k by
means of the flange n on the shaft which latter works in bearings p on the
plate g.
The tool box r is fixed behind the wheel axle d and its covers at the same time-
serves as the driver's seat.
For using the plough the share / has to be adjusted so that its shaft k makes such.
an angle with the wheel axle d that the forward part of the share edge situated in
the horizontal central plane of the share comes nearly parallel with the direction of
motion of the plough. In the forward motion of the plough the edge of the share
penetrates into the soil to the depth of furrow defined by previous adjustment and.
that owing to the weight of the plough itself and that of the driver.
The severed earth strips rise upon the hollow surface of the dish-shaped share in.
consequence of the angular position of same and when come to a certain height
turn over to one side. When the first furrow has been made the furrow wheel c
which is larger in diameter than the other wheel in accordance with the depth of
furrow produced, runs into the said first furrow, while the share acts in the manner
described and lays the raised earth strip off in the first furrow. In consequence
of the rolling action of the share the friction and consequently the wear of the
working parts are reduced to a minimum. Furthermore in consequence of this
peculiar mode of working the plough requires only a comparatively small draught
power. The plough may be made with one or more shares.
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
A moto touch having
dish shaved chara such as 1 with knife like

page_text: edge and smooth hollow surface which is directed forward and at an adjustable
angle with the direction of furrow, so that as the share rolls the earth strips
severed by its cutting edge rise on the hollow surface of the share and are
then diverted and laid over towards the peceding furrow substantially as
set forth.
Second. The construction of rotary plough described with reference to the
drawing.
