Improvements in Ploughs.
I, JOHANN FRIEDRICH WITTHOLD, of Döhlen, near Huntlosen, in Oldenburg,
Empire of Germany, Farmer, 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:-
In the ploughs hitherto commonly used the disadvantage has been remarked
that undivided clods, particles of manure and the like get between the plough-
share, share-holder and plough-tree, which must be removed after a short time
to enable the continuance of the ploughing.
A small cutter is sometimes used in front of the plough-share, but this does
not however suffice to remove the disadvantage, which is the object of the present
invention. The share-holder is given a special form which acts like a wedge,
so that the adherence of clods of earth or manure above the share of the plough
cannot take place.
By this arrangement the digging in of the manure by hand labour is rendered
unnecessary, as this is effected automatically, which means a great economy of
labour.
One form of the invention is shewn in the accompanying drawing,
Fig. 1 being a side elevation,
Fig. 2 a plan of the plough, partly in section,
Fig. 3 a sectional plan of the share of the plough on line of Figure 1,
Fig. 4 a front elevation of the share, partially in section.
As will be seen from Figure 1 of the drawing the share-holder is attached
to the share a of the plough by means of bolts c.
The share-holder b has now above the share a a spiral twist das will be seen
from Figs. 1 and 3 of the drawing, which acts like a wedge upon the clods of
earth and particles of manure raised by the share.
By this means the adherence of anything below the plough-tree e which could
interfere with the action of the plough is avoided and it is assured that a part of
the manure raised be pressed into the furrow to be ploughed.
The manure which is distributed at the part d of the share-holder b, is pushed
towards the left and right, and on the right-hand side it falls into the neighbour-
ing furrow, whereas on the left-hand side it falls into the new furrow thrown up.
The manuring of the furrows is regulated by providing the share-holder b with
slots f, in which the bolts c can glide which connect the share a of the plough
to the share-holder b.
The adjustment of the blade in a vertical direction is made possible by the
slot g in the top of the share-holder b, in which the plough-tree e is adjustably
secured by means of a nut h.
As usual a shoe i arranged at the bottom of the blade a in the direction of
the furrows furnishes the guidance, whereas by means of the handles k, direction
can be given to the plough.
The action of the plough depends upon the peculiar form of the share-holder b

page_text: by means of which the distribution and the, as far as possible, frictionless move-
ment of the earth and manure is effected.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1/. A plough-share-holder, the part above the plough-share a of which has an
approximately wedge-like form for the purpose of distributing the manure raised
by the share a.
2/. A device as set forth in Claim 1 in which bolts c secured to the share a
for the purpose of attaching the same to the plough-share-holder b, are guided
in slots f, for the purpose of enabling the adjustment of the share to the share-
holder to produce a different distributing action.
