An Improvement in Pulverizing Ploughs.
Year: 1898

page_text: I, THOMAS CONNOR, Junior, of Cushenstown, Ashbourne, County, Meath,
Ireland, Farmer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to an improvement in chill or other ploughs
whereby such agricultural implements may be rendered more useful than
hitherto,
The invention consists in affixing to the frame of the plough immediately
behind the "share" and at right angles to the frame a horizontal lever on which
is mounted a sliding block.
This sliding block carries a vertical knife capable of vertical movement in the
block so that its position may be adjusted as required, and may be held fast by
means of a suitable set screw inserted through the wall of the block which latter
may also be made fast on the horizontal lever by a similar set screw.
66
As thus arranged the horizontal position as also the "dip" or depth " of this
vertical knife may readily be adjusted, and its function is to cut up the sod' in
the rere of the share.
The right angular position of the horizontal lever may be strengthened by
means of a stay rod between its free end and the frame of the plough.

An Improvement in Pulverizing Ploughs.
I, THOMAS CONNOR, Junior, of Cushenstown, Ashbourne, County Meath,
Ireland, 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:-
This invention has reference to an improvement in chill or other ploughs
whereby such agricultural implements may be rendered more useful than
hitherto.
The invention consists in affixing partly to the frame of the plough and to the
mould-board immediately behind the ordinary "share" a lever, one arm of which
lies horizontally at right angles to the frame and on which is mounted a sliding
block

page_text: The sliding block carries a vertical knife capable of vertical movement so that
its position may be adjusted as required and may be held fast by means of a suit-
able set screw inserted through the block, which latter may also be made fast
on the horizontal arm of the lever by a similar set screw."
As thus arranged the horizontal position as also the "dip" or depth of the
vertical knife may readily be adjusted, and its function is to cut up the sod in the
rere of the ordinary share.
The right angular position of the horizontal lever may be strengthened by
means of a stay rod, or chain between its free end and the front frame of the
plough, or otherwise as may be found convenient.
The accompanying drawings will enable my said invention to be more readily
understood and carried into practice.
Fig. 1 is an elevation of an ordinary plough shewing the application of my
invention thereto.
Fig. 2 is a plan of same and,
Fig. 3 is a front view of the knife detached.
A is the lever attached to the inner surface of the mould-board to the rear of
the share and running backwards, then upwards, and laterally as shewn.
Its position is strengthened by stay rods B.
On the right angular arm is the sliding block C whose position may be fixed
by the set screw C¹.
In the block is hung the rod D) which carries the knife D¹ the depth of which
may be adjusted by the set screw I)².
t
It will be perceived at a glance that by this arrangement the sod behind the
ordinary share can be cut up or pulverized in a simple and effectual manner.
The right angular arm of the lever A may be strengthened by a chain E one
end being secured to a collar E and the other end to a collar E², both collars
being held in position by suitable set screws.
By moving the collar E¹ on the lever A the tension of the chain may be
adjusted.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
In combination with chill or other ploughs the use and application of a device
consisting of a knife D¹ carried on a vertical rod 1) and hung in a sliding block C
mounted on a lever A whereby the position of the knife both horizontally and
vertically may readily be adjusted, substantially in the manner and for the
purpose as herein described and set forth in the accompanying drawings.
Dated this 18th day of November 1898.
