exible Harrows.
I, WILLIAM OGLE of the Firm of G. C. Ogle & Son, Perseverance Works,
Ripley, in the County of Derby, Agricultural Implement Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in what are known as flexible harrows
which are formed by a number of corresponding members flexibly jointed together,
each member being formed of one piece of metal bent to the required shape.
In carrying out this invention, each member is formed L shaped in plan, with a
horizontal loop or bow preferably on the exterior of the angle formed by the
junction of the two straight parts. The ends of the straight parts are formed with
preferably vertical bows the end of the bow on preferably the shorter straight
part, being continued vertically so as to form a tine."
Each member is formed by bending a bar of metal of suitable section into the
shape described, the angle between the two straight parts being varied to suit
different requirements.
In connecting the members together the vertical loop or bow at the end of one
of the straight parts, engages with a horizontal loop at the angle of one of
the members in the preceding row, and the vertical loop at the end of the other
straight part with the horizontal bow at the angle of the one next to it in the
same row.
The whole of the members in the harrow may be arranged in the same
manner throughout, but I preferably form the members in one half of the harrow,
with their transverse straight parts in the reverse direction to those in the
other part.
In an alternative arrangement the members in plan are formed so as to
correspond to the three sides of a parallelogram. Horizontal bows are formed on
the exterior of each of the two angles, and the two free ends are each formed
with a vertical bow the end of which is continued vertically so as to form
a tine.
With this arrangement the horizontal bows at the angle of each member engage
with the vertical bows at the free ends of the corresponding member in the
preceding row, and a space is formed between the members in each row, by straight
links formed with vertical bows to engage with the horizontal bows at the angles
of each member.

page_text: Improvements in Flexible Harrows.
I, WILLIAM OGLE, of the Firm of G. C. Ogle & Son, of Perseverance Works,
Ripley, in the County of Derby, 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 relates to improvements in what are known as flexible harrows,
which are formed by a number of corresponding links or members flexibly linked
together.
The invention will be best understood by reference to the accompanying
drawings in which :-
Fig. 1 is a plan of a harrow constructed according to my invention.
Fig. 2 is an elevation, and
Fig. 3 a plan of one of the links or members.
Fig. 4 is a side elevation of one end of a link or member.
Figs. 5, 7 and 9 are elevations, and
Figs. 6, 8 and 10 the respective plans of links for the two side edges of the
harrow.
Figs. 2 to 10 inclusive are drawn to a larger scale than Fig. 1.
Like letters indicate like parts throughout the drawings.
In carrying out this invention the harrow is formed of L shaped links or
members A flexibly linked together as shown. Each link A is formed with two
preferably straight parts A' A³ (see Figs. 2, 3 and 4) placed at an angle to each
other with a longitudinal loop or bow B formed preferably on the exterior of
the angle.
The end of the shorter part A' is formed with a vertical bow C, and the end of
the longer part A' with a vertical bow D and the end of the latter continued
downwards to form a tine E.
If preferred the. tine E may be formed at the end of the short straight part A',
the loop or bow B. may also be placed vertically and the bows C and D horizontally
dr at any other convenient angle.
Each link or member A is preferably formed by bending a bar of metal of
suitable section into the shape described, the angle between the two parts A1 A³
being adjusted according to the distance the tines are to work from each other.
In the drawings the angle is shown to be greater than a right-angle, but the same
result may be obtained by making the angle the same number of degrees less than
a right-angle.
In connecting the links or members A. together, they are arranged in parallel
rows, the first row being connected by loops or bows B to the rail G. The bow C
of each link or member engages with the loops or bow B of the one next to it in
the same row, whilst the bow D engages with the loop or bow B of the corresponding
link or member in the next row.
At the left hand side of the harrow as shown in the drawings, the last link H in
part of the rows is formed as shown in Figs. 5 and 6. The links H are formed
with a
loop or bow B, a straight part A provided at the end with a bow D and
tine E, and a straight part A3 which is twined in the reverse direction to the
part A of the links A, and is provided with a hook I to engage with the straight
part A of the link next to it in the same row.
With this arrangement the tine on the last link H is maintained in a vertical
position.

page_text: The last link J on the left-hand of the remaining rows is formed as shown in
Figs. 7 and 8.
These links J are formed with a part A' provided at the end with a bow D and
tine E, a second part A provided with a bow D and tine E and a loop or bow B at
the exterior of the angle formed by the two parts A2 A.
The bow D at the end of the part A' engages with the bow B of the last link H.
in the next row.
On the right hand side of the harrow the end links K on every two or more rows
are formed as shown in Figs. 9 and 10.
These links K are formed with a part A' provided at the end with a bow C, a.
loop or how B, and a part A provided with a bow D to engage with the loop or-
bow B of the end link A of the next row.
In making a harrow which is to be drawn both ways, the links in the first part.
are placed as shown, but in the last few rows, the position of the links are reversed
and the first row of reversed links connected to the other part by straight links of
the requisite length. In some cases the links or members A may be formed with
the part A' at right-angles to the part A
The part A is in this case formed with a loop or bow midway between the loop.
or bow B and the bow C, and in placing the links together the additional bow of
each link engages with the bow D of the corresponding link in the preceding row.
With this arrangement the links in each row will be situated to the right or left
of those in the preceding row, and the tines of one row will thus be out of the-
track of those of the preceding row.
In an alternative arrangement the links or members may in plan be formed to.
correspond in shape to the three sides of a parallelogram. Loops or bows are.
formed on the exterior of each of the two angles, and the two free ends are each
formed with a bow and the end continued downwards to form a tine.
With this arrangement the loops or bows at the angles of each member engage.
with the bows at the free ends of the corresponding members in the preceding row,
and a space is maintained between the links or members in each row by straight
links formed with a bow at each end to engage with the horizontal bow at the
angles of each member.
Having now particularly described and ascertained the nature of the said inven--
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A flexible harrow formed of
substantially as described.
shaped links such as A linked together
2. A flexible harrow formed of L shaped links such as A each provided with a
loop or bow B, bows C and D and tine E, substantially as described.
3. A flexible harrow formed of L shaped links each provided with a loop or
bow B, bows C and D a tine E and a loop or bow between the bows B and C
substantially as described.
4. A flexible barrow formed of links which correspond in shape to the three-
sides of a parallelogram each formed with bows at the two angles and a bow and
tine at each of the free ends substantially as described.
5. The combination and arrangement of parts constituting the complete flexible-
harrow substantially as described and illustrated in the accompanying drawings.
