also suitable for use for other ploughing purposes and is of a peculiar construction
which enables the work of ploughing to be done expeditiously and more conveniently
than this has been able to be done heretofore.
Referring to the accompanying drawings
Fig. 1 is a side elevation.
Fig. 2 is a plan of the plough.
Figs. 3 and 4 illustrate in section the swivel plough beam and the rotary shaft
combined therewith by means of which the plough-shares are adjusted.
Figs. 5 to 11 contain detail and other views of the construction on a larger
scale.
A peculiarity of the construction according to our present invention lics in the
use of a beam C pivoting on a pin B (like a turn-table) within the plough frame A
and on or to this beam there are fixed several plough-shares one behind the other
in combination with a shaft capable of rotating about its axis above the plough
beam said shaft serving to enable the shares to be shifted according to which way
work is to be done.
+
The construction is as follows:-
The frame A rests on a hind wheel and two front wheels by shifting which in a
forward and rearward position the working depth can be increased or decreased.
The plough-shares can be removed entirely from off the ground. This is
effected by means of the levers (engaging at both sides in a circular toothed-
arca) the connecting rods and bent levers d which latter are pivoted to the main
frame A and at their lower ends carry the front wheels said bent levers: being
capable of turning about the axle 7.
C
In Fig. 1 the extreme positions (or thereabouts) of the front wheels are indicated
which determine the working depth of the shares. The hind wheel may be shifted
(ie. adjusted vertically) in accordance with this bigher or lower position of the
front wheels or otherwise as follows:-The fork W which receives the axle. of
this wheel X is provided with a projecting rod Y which is removable in the sleeve A¹
fastened to the frame A; the mentioned sleeve is provided with a binding screw Z
which allows of the fork's being fixed at any desired height.
Within the frame A and resting upon the middle cross support T and capable of
being swung on the vertical pin or axis B is the plough-bean C which is
advantageously composed of rods of flat bar iron or otherwise suitably constructed
and which for the purpose of more secure guidance during adjustment slides on
the two cross supports T' and T³.
On the ploughbeam C there are situated and firmly mounted the four fixed share-
carriers R to the lower end of each of which latter respectively there are mounted
the shares in such manner that each of the latter is respectively capable of rotation
about a pin or axle f.

mounted on it.
"
By means of rods i chain K and chain pulley or sprocket wheel these arms L¹
allow of rotating the symmetrically shaped shares which are provided with cutting
edges on both sides and are capable of rotation about their said axes f. The
turning of the shaft g to the right or to the left and consequently the turning of
the shares is effected by suitably rotating the hand lever h. The position
marked I-I and shown in Fig. 2 of the plough beam C corresponds with the
working to the right hand. Left hand working is indicated by the position
indicated by 11-11 in Fig. 2.
In the former case the cutting edges of the shares are turned towards the left
hand and in the latter case towards the right hand and the respective positions are
shown in Fige. 9 and 10.
In consequence of the oblique position of the ploughbeam it is not necessary to
fasten it specially but it may however be fastened by means of a peg or stop X
(Figs. 5 and 6) to be inserted by hand or by means of a spring catch that comes
into operation automatically whilst the shares themselves are held in the requisite
position by means of pins or studs fixed thereon. Fig. 11 illustrates a section
through the share. Figs. 5 and 6 illustrate (on a larger scale) the mounting and
construction of the movable plough-beam C.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A multiple share plough having a movable plough-beam such as C which at
the end of every furrow is adapted to be shifted from one diagonal into the other
diagonal of the plough framing A in combination and acting in conjunction with
plough-shares pivotally mounted and adapted to be rotated and apparatus for
reversing or turning the said plough-shares substantially in the manner and for the
purposes herein before described and illustrated in the drawings hereunto annexed.
2. A multiple-share plough having a movable plough-beam such as C which at
the end of every furrow is adapted to be shifted from one diagonal into the other
diagonal of the plough framing A in combination and acting in conjunction with
plough-shares pivotally mounted and adapted to be rotated, apparatus for reversing
or turning the said plough-shares consisting of a shaft such as g mounted in
bearings in the said plough-beam a hand-lever h to operate said shaft and a two-
armed lever such as L' fixed on said shaft g from whose ends rods such as i and
wire ropes or chains such as K pass round a sprocket wheel such as fixed to the
horizontal pin f respectively carrying each said plough-share whereby when the
hand-lever is turned the plough-shares are rotated and are fixed in their position
by pins fixed thereto striking against the carrier R all substantially in the manner
and for the purposes herein before described and illustrated in the drawings
hereunto annexed.
3. The improved construction of ploughs arranged combined and acting
substantially in the manner and for the purposes herein before set forth.
