page_text: I, FORDHAM MOTE of Burnham Market in the county of Norfolk, Agricultural
Implement Manufacturer do hereby declare the nature of this invention to be as
follows:-
The invention consists in the employment of a number of revolving harrows
fixed or suspended to a suitable carriage whereby I produce a harrow which will
with advantage replace the ordinary drag harrows now in use and the invention
further consists in improvements in the construction of revolving harrows suitable
to be attached to a plough or other implement.
In carrying out my invention I employ a number of revolving harrows to replace
the ordinary drag harrows; I provide a frame mounted on suitable wheels and
having draught poles or other means of attachment for horses or other power; to
the said frames I suspend the revolving harrows of suitable construction in such a
manner that they can be regulated to work at any required angle by means of a
lever which can be operated by the attendant, the aforesaid wheels serving to allow
of the implement being drawn over the ground. By this arrangement a great
reduction of draught is effected over harrows as hitherto constructed at the same
time that the strength of the harrow is considerably increased.
The improved revolving harrows I find it advantageous to employ according to
my invention, are made with tines or teeth of steel and in pairs, each pair being
somewhat in the form of a staple; the tines or teeth so formed are passed through
holes in a ring or circular frame and are attached thereto in any suitable manner
such as by means of a screw threaded hook or clip and nut; against the inner
circuinference of the circular frame revolve grooved friction rollers on a frame
provided with arms adapted to be attached to the harrow frame, and having eyes
for receiving brackets which are attached by means of clips or other suitable
means to a plough tail or handles when the improved harrow is to be attached to
a plough.
Suitable means are provided for regulating and holding the revolving harrow to
any required angle with the ground.
By this construction the harrow or combination of harrows in rotating is or are
supported at the outer edge instead of at the centre as hitherto whereby greater

page_text: rigidity and strength are given to the harrows, and much heavier work can be
performed with a lighter harrow; further the cost of manufacture is considerably
reduced and I produce a much stronger harrow than heretofore and provide greater
facility for rapidly attaching such implement to and detaching it from a plough or
the like when the harrow is used in combination with a plough.
Improvements in Harrows.
I FORDHAM MOTE of Burnham Market in the county of Norfolk, Agricultural
Implement Manufacturer, 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 consists in the employment of a number of revolving barrows
fixed or suspended to a suitable carriage whereby I produce a harrow which will
with advantage replace the ordinary drag barrows now in use, and the invention
further consists in improvements in the construction of revolving harrows suitable
to be attached to a plough or other implement.
In carrying out my invention I employ a number of revolving harrows to replace
the ordinary drag harrows; I provide a frame mounted on suitable wheels and
having draught poles or other means of attachment for horses or other power; to
the said frames I suspend the revolving harrows of suitable construction in such a
manner that they can be regulated to work at any required angle and can be lifted
when required by means of a lever which can be operated by the attendant, the
aforesaid wheels serving to allow of the implement being drawn over the ground.
By this arrangement a great reduction of draught is effected over harrows as
hitherto constructed at the same time that the strength of the harrow is considerably
increased.
The improved revolving harrows I find it advantageous to employ according to
my invention, are made with tines or teeth of steel, and in pairs, each pair being
somewhat in the form of a staple; the tines or teeth so formed are passed through
holes in a ring or circular frame and are attached thereto in any suitable manner
such as by means of a screw threaded hook or clip and nut; against the inner or
outer circumference of the circular frame revolve grooved friction rollers on a frame
provided with an arm or arms adapted to be attached to the harrow frame. The
said arms are provided with eyes for receiving brackets which are attached by
means of clips or other suitable means to a plough tail or handles when the
improved harrow is to be attached to a plough.

page_text: Suitable means are provided for regulating and holding the revolving harrow at
any required angle with the ground.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which Figure 1 represents
a rear elevation and figure. 2 a plan of a barrow constructed of a number of
revolving harrows arranged so as to replace an ordinary drag harrow according to
my invention. Figure 3 is a longitudinal section on the line A, B of Figure 2.
Figure 4 represents a perspective view of my improved revolving harrow the frame
being shewn provided with eyes and brackets to allow of the harrow being attached
to a plough. Figure 5 represents a central vertical section and Figure 6 a plan
of the same; Figure 7 is an elevation of a pair of my improved tines or teeth and
figure 8 is an elevation of the screw threaded hook for attaching the said tines or
teeth to the ring or circular frame of the harrow. Similar letters represent similar
parts throughout the several figures of the drawing.
Referring to figures 1 to 3, a, is the frame of the harrow mounted on wheels b,
and provided with draught poles c, for the attachment of horses or the like thereto.
The wheels b, serve to allow of the implement being drawn over the ground and
are mounted on an axle d which extends across the machine; on the axle d, are
loosely arranged sockets e, in which are held, by means of set screws f, the arms g,'
on the frames g¹, of the revolving harrows h, thereby allowing the said arms to be
turned round so as to set the revolving harrows at any required angle.
The revolving harrows h, are suspended by means of chains h¹ and hooks h²,
from bars i, fixed on a shaft 2, which is journalled in the sides of the frame a;
1, is the lever working on a quadrant, and which can be operated by the attendant
for the purpose of regulating the revolving harrows h, to work at any required
angle and to allow of their being lifted when required, the height or depth when
working being regulated by lengthening or shortening the chains h¹, on their
hooks, when required. The revolving harrows h, by being loosely attached by
means of their arms g, and the sockets f, to the axle d, will automatically adjust
themselves to the varying level of the surface of the ground over which they travel
when at work and by being placed at unequal distances from the axle d, as shewn
in figure 2 they will each deliver the rubbish onto the top of the soil clear of one
another.
I will now describe my improved revolving harrow by reference to figures
to 8;, is the ring or circular frame; L, l, are my improved tines or teeth formed
in pairs somewhat in the form of a staple as shewn clearly in Figure 7, which
represents a frout elevation of one of the said pairs; m, m, are the screw threaded
hooks or clips and m³, m' are the nuts for fixing the tines or teeth, to the ring
or circular frame k, when the tines have been passed through holes in the ring or
circular frame k, (as shewn in Figure 5) Figure 8 represents an elevation of one
of the said looks m and nuts m¹; n, n, are the grooved friction rollers attached
to the frame g¹, of the harrow which rollers revolve against the inner circumference
of the circular frame k, when the harrow is caused to rotate p¹, pl, are the eyes
with which I provide the arms g, on the frame g¹, for the purpose of allowing my
improved revolving harrow to be attached to a plough; q, q, are the brackets,
placed in the eyes p', and r, r, are the clips for fixing the brackets q, to the plough
tail or handles, the harrow being held at any required angle with the ground by
means of the bar 8, which is also fastened to the plough in any suitable manner.
By this construction the revolving harrow or combination of harrows in rotating
is or are supported at the outer edge by means of the grooved friction rollers n,
instead of at the centre as hitherto whereby greater rigidity and strength are given
to the harrows, and much heavier work can be performed with a lighter barrow;
further the cost of manufacture is considerably reduced and I produce a much
stronger harrow than heretofore and provide greater facility for rapidly attaching
such implement to and detaching it from a plough or the like when the harrow is
used in combination with a plough.

page_text: Although I have described and shewn my improved harrow with the grooved
friction rollers working over the inner periphery of the ring or circular frame it
will be obvious that by increasing the size of the frame which carries them they
can be arranged to work over the outer periphery of the ring.
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. The combination with a carriage of suitable construction of a number of
revolving harrows arranged and operating so as to replace an ordinary drag harrow
substantially as hereinbefore described.
°
2. A revolving harrow constructed of a ring or circular frame over the inner or
outer periphery of which revolve grooved friction rollers carried on a frame adapted
to be attached to a plough or other implement substantially as hereinbefore
described and represented in the accompanying drawing.
3. The improved tines or teeth for revolving harrows hereinbefore described and
represented in figure 7 of the accompanying drawing.
4. The improved harrows hereinbefore described and represented in figures 2 to 6
of the accompanying drawing.
