A Harrow.
JOHN SPENSER COATES Tankersley Ballinglen Rathdrum County Wicklow
Ireland Farm Manager do hereby declare the nature of this invention to be as
follows:-
A harrow consisting of a number of plates connected together by rods. Each
plate has a hole near each end, through which passes a rod. On the rods, loops are
turned behind each plate, into which loops, the ends of the succeeding rods are
looped. The plates are placed on their edges, running in parallel lines a space
being left between the right hand hole in the first plate and the left hand hole in
the second plate, equal to the distance between the holes in each plate.
The plates of each alternate row being placed opposite the spaces in the
foregoing row of plates.
Dated this 3rd day of July 1894.

I, JOHN SPENSER COATES, of Tankersley, Ballinglen, Rathdrum, County
Wicklow, Ireland, Farm Manager, 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 relates to a
construction.
new or improved harrow of simple and effectual
In carrying out my invention I arrange a number of rectangular plates of
suitable dimensions on their longitudinal edges, and running in parallel lines to each
other. These plates which are pierced by a hole at both ends are connected to
each other by rods or links in the following order.
Through each hole is passed a rod or link of suitable length provided with a loop
at its rear end and a hook at it front end.
The plate abuts against these loops. In this way the plates are coupled up in
such a manner that the plates of each alternate longitudinal line will be opposite
the space in the adjoining longitudinal line.
In order that my said invention may be more readily understood and carried into
practice, I attach the accompanying drawings.
Fig. 1, is a plan view of my improved harrow complete; and Fig. 2, an enlarged
detail. a, a, are the rectangular plates; and b, b, the connecting rods or links.
It will be observed that in coupling up the plates, a space is preserved between
the right-hand hole in the first plate, and the left hand hole of the next plate in
the adjoining longitudinal line which space is equal to the distance between the
holes in each plate.
It will be also observed that taking the harrow transversly we have, as above
stated, a plate and a space alternately in each longitudinal line.
It is obvious that in a harrow constructed according to my invention, the plates
are maintained in a constant vertical position, thereby presenting their edges

page_text: constantly to the ground, while considerable strength and flexibility are obtained,
and all the advantages of a chain connected harrow preserved.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I would have it understood
that what I claim is :-
First. In harrows, the combination formed by the rectangular plates a, a, and
connecting rods or links b, b, in the manner substantially as described and
illustrated.
Second. The use and application of harrows, constructed, arranged and operating
in the manner substantially as herein specified and set forth.
Dated the 28th day of March 1895.
