Complète Specification Left, 15th Feb, 1895-Accepted; 6th Apr., 1895
.
I, SAMUEL WILLIAM CAMPAIN, of Deeping Saint Nicholas, in the County of
Lincoln, Farmer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in cultivators and the object of it is to
provide an implement capable of cutting through the roots of weeds growing
between the plant roots, as well as through the roots of those growing between the
individual plants along and in the rows and in the latter case at a level beneath the
roots of the plants.
In carrying this invention into effect, I provide a suitable beam or frame which
may be mounted on one or more carrying wheels as may be required or found
convenient. From such beam or frame there hangs a suitable slade. To this slade
are fixed in any convenient way two shares or knives; one in front of the other,
each share projecting preferably, from both sides of the slade. I prefer that there
should be two shares, a leader and a follower, because then, roots missed by the
former will be cut by the latter, and also, the strain on the latter when the ground
is very hard, e.g:, in winter, will be lightened..
The outer ends of the follower are each fitted with a knife or share projecting
right and left far enough and at a sufficiently low level to cut beneath the roots of
the plants.
My invention does not confine me to the number of the above described slades
with their accompanying knives or shares, inasmuch as a cultivator may be made
according to my invention to deal with as many pairs of rows of plants as may be
desired or considered convenient.
The slade above mentioned is useful for preventing the knives or shares cutting
down into the ground. It may be dispensed with if desired, and the knives or
shares.be carried by stalks.
The invention does not confine mesin respect of the number of knives or shares
mentioned. The latter may be varied in respect both of size and shape and may
be detachable from each other as well as from the slades or stalks as the case
may be..
They may be made so as to be fitted to any existing implement having the
necessary, adaptability to serve as the frame for them.
Dated this 16th day of May 1894.

I, SAMUEL WILLIAM CAMPAIN, of Deeping Saint Nicholas, in the County of
Lincoln, 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:-
:
My invention relates to improvements in cultivators. and the object of it is to
provide an implement, or a detachable addition to one, capable of cutting through
Price 8d.1

page_text: the roots of weeds growing between the rows of plants, as well as through the roots
of weeds growing between the individual plants along and in the rows, and in the
latter case, at a level beneath the roots of the plants.

The invention therefore consists in a 2-level knife or share. By the term 2-level
knife or share is to be understood one that presents two cutting edges to the work,
one edge standing then on a higher level than the other. The particular means
employed for holding the 2-level knife or share in working position and carrying it
through the ground may be of any suitable type, because they are not a substantial
part of the present invention.
Referring to the accompanying figures, which are to be taken as part of this
Specification and read therewith,
Figure 1 is a side elevation shewing my invention fixed to a special slade and the
latter to a plough frame.
Figure 2 is a plan of Figure 1.
Figure 3 is a rear elevation corresponding with the preceding figures and
including in section the width of ground occupied by four rows of plants.
Figure 4 is a plan of a 2-level knife or share duplicated and with a tab by
which the duplicated knife or share can be bolted to its slade or to the equivalent
of the latter.
a is the top level knife or share; b is the bottom level knife or share; and c is
the connecting piece that holds one to the other. I prefer that these three pieces
shall be in one forging but the invention does not limit me in this respect. Both
knives have a rearward rake as is common with the knives of horse hoes and in
addition to this rearward, I prefer that the bottom level knife shall have its heel
curved to the front, as already illustrated in Figure 4, the better to ensure the
severance of the roots in the path of the rear or outer portion of such knife. But
the shape of both top and bottom knives may be varied as be desirable.
The widths of the paths of the top and bottom level knives are settled according
to the width between the rows, of plants and the widths of the rows themselves.
One of my improved knives or shares deals with half the width between two rows
of plants as well as the width under one row. But propose to always duplicate
them, that is to join them by the leading ends of the top level knives a, a, to a
stout tab d from which they both rake right and left. Bolt holes d', d' are made
through this tab and through these holes are passed the holding bolts d², d³, by
which it is held to the tail of the slade e or to the equivalent of the latter. The
conjunction of the two improved knives or shares, both having a rearward rake,
with the connecting tab d produces a Y shaped construction, shewn in Figure 4,
capable of dealing at one time with the roots of all the weeds growing between
two rows of plants, f, as well as with those of all weeds growing in and along such
rows, and also of being readily fixed to the frame of a suitable implement.
of
The vertical distance between the levels of a top and a bottom knife, a and b, is
adjusted so as to make sure that the latter shall miss the roots of the plants f, f.
The slade e is shewn as a flat bar. It is bolted to the bottom of the frame
the plough, along the longitudinal centre thereof, as heretofore. Provision is
made, by means of a series of bolt holes for adjusting the position of the
improved knives or shares with reference to the plough frame.
Any provision, other than that shewn in the figures, for supporting the sinde
and the duplicated improved knife or share, may be made use of, but the one
illustrated is a suitable and convenient one for providing for the advantageous use
of the present invention.
In addition to the duplication illustrated in the figures and described above, two
such duplicated knives or shares may be bolted to ope slade, one in front of the
other. The advantage of this last mentioned arrangement is that any roots missed
by the leading knives or shares, will be cut by the following pair.
As many combinations of slades and improved knives or shares may be carried
by the frame of one implement as may be desired, so as to deal with the weeds
growing between and along more than one pair of rows of plants.

page_text: The slade above described is useful for preventing the knives or shares cutting
down into the ground. It may be dispensed with if desired, in which case the tab d
will be bolted directly to the frame of the implement or the improved knives or
shares be carried on the ends of stalks.
The improved knives or shares may be detachable, independently of each other
from tab, stalk, or slade.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The hereinbefore described 2-level knife or share.
2. The herein before described combination of duplicated 2-level knife or sharo
and tab.
3. The herein before described combination of 2-level knife or share with a
particular means for holding it in working position and carrying it through the
ground.
