OR IMPROVED HARROW." (A communication by Robert Cockerell, of Melbourne,
Australia.)
.
My Invention consists of a rotary harrow. In carrying out my Invention I
adopt mainly the following arrangements :-
1
Fixed on jointed rods are arranged tines or teeth formed in the way of serrated
bobbins or flange wheels, the jointed rods allowing of the rollers yielding to the
inequalities of the ground, these being placed at an angle to their draught, giving
a tearing motion, its rotating movement allowing it to pass over roots, stones, and
other obstructions.
This improved harrow can be made in various shapes, and in its operation it can
scarify, harrow, roll, and clodcrush the land as required.

"NEW
JOHN ELKINGTON, of Coleman Street, in the City of London, Merchant.
OR IMPROVED HARROW." (A communication from abroad by Robert Cockerell, of
Melbourne, Australia.)
This Invention consists of a rotary harrow. In carrying out the Invention I
adopt substantially the following arrangements :—
Fixed on jointed rods are arranged tines or teeth formed in the way of serrated
bobbins or flange wheels, the jointed rods allowing of the wheels yielding to the
inequalities of the ground, these being placed at an angle to their draught, giving
a tearing motion, the rotating movement allowing it to pass over roots, stones, and
other obstructions.
This improved harrow can be made in various shapes, and in its operation it can
scarify, harrow, roll, and clod crush the land as required.
In order that the nature of the Invention may be clearly understood, I will
now proceed by reference to the accompanying Drawing to further and particularly
describe and ascertain in what manner the same is to be performed or put in
practice.
DESCRIPTION OF THE DRAWING.
The Drawing shows plan view of the new or improved harrow.
A are the jointed rods on which are arranged, as shewn, the bobbins or flange
wheels B. These wheels B arranged at an angle to the line of draught give a
tearing motion and so operate effectually on the land, but as B rotate they will
pass harmless over roots and stones or other obstructions. It is obvious that the
harrow may be constructed in various forms to meet requirements.
Having now particularly described and ascertained the nature and object of
the said Invention, and in what manner the same is to be performed or carried
out in practice, I hereby declare that I claim the Invention of "New or Improved
Harrow," substantially as herein before set forth and described and illustrated by
the accompanying Drawing.
In witness whereof, I, the said John Elkington, have hereunto set my hand
and seal, this Thirtieth day of May, in the year of our Lord One thousand
eight hundred and eighty two.
Witness,
W. HILLIER,

Charing Cross.
