An Improved Pulverizing Attachment for Ploughs.
I, ALFRED WILLIAM LEGG, of Balclutha, in the Colony of New Zealand, Black-
smith, 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:-
The object of this invention is to break up the ground more thoroughly than
is now usually done by ploughs, and the ground will in fact be left more as if
it had been well dug. To do this I attach to any plough one or more attachments
in the form of a disc cutter or splitter, or skimmer, or a knife. These are pre-
ferably attached to the plough beam in such a manner that they are capable of
being adjusted to any required position or another form than the one on, may
be substituted for different conditions of the ground. These when in position
skim or divide the soil, grass or furrow.

Referring to the accompanying drawing:
Figure 1, is an elevation of part of a plough with the invention attached,
showing a disc cutter and also a knife held as a grass cutter. Fig. 2, is a plan

of same.
B, is a suitable attachment shown as two screw eyes securing a bent bar which
holds a block having holes crosswise in it, one of these holes is used for securing
the block E, to the bent bar, and the other hole takes the stalk or shank of the
knife C, or the spindle of the disc cutter D.
Adjustments may be made at both holes and also at the eyes B, by means of
the set screws and nuts as shown.
E, E, are the blocks preferably as shown with two holes at about right angles
and set at an angle one inwards and one outwards for better adjustment as shown.
These holes though shown round may be of any shape, and in some cases
When desired the disc cutter
square ones would be found to hold more firmly.
may be replaced by any knife of a substantially similar shape to C, perhaps bent
differently, for splitting the furrow and either of the knives may be used
separately.
Blocks such as F, may be used at B, B, roughened at the hollow to better secure
the bent bar holding E.
In this invention any sizes or materials may be used.
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. In any Plough, the combination of such plough with a circular disc cutter
(such as D,) and a skimming knife (such as C,) both of which are held in
position by blocks (such as E, E,) bent bars and eye attachments (such as B, F,)
the said cutter D, being free to revolve, all substantially as described and
explained and as set forth in the drawing.

page_text: 2. In any plough the combination of such plough with a splitting or skimming
knife (such as C,) or a knife bent to other shape but of substantially the same form
and for the purposes of splitting the furrow substantially as set forth herein and
as described in the drawing.
