IMPROVEMENTS IN THE MANUFACTURE OF HARROWS, CULTIVATORS, AND OTHER SIMILAR AGRICULTURAL IMPLEMENTS
Year: 1865

Commissioners of Patents, with his Petition, on the 6th April 1865.
I, JOHN BADGER, of Worcester, Ironmonger, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF HARROWS,
CULTIVATORS, AND OTHER SIMILAR AGRICULTURAL IMPLEMENTS," to be as follows:-
My Invention consists of the improvements herein-after explained in the
manufacture of barrows, cultivators, and other similar agricultural implements,
whereby the parts of which the harrow or implement is composed are made
without welding, and are fixed together by the driving in of the tines, or by
a key or wedge.
I will describe my Invention as applied to a harrow. In the ordinary
barrow the framing is made of a series of bars crossing each other, the tines
being fixed at the intersections of the bars. In making a harrow according
to my Invention I bend bars of iron into a zig-zag form, or a form resembling
that of a series of the letter V, and in combining them to form the frame of a
harrow I present the angles of one zig-zag bar to the angles of the next
zig-zag bar, binding the angles together in the manner berein-after explained.
The general figure of the framing thus produced nearly resembles that of the
ordinary harrow. The angles of the zig-zag bars of iron do not come into.
contact, but are separated by two parallel bars of iron, the said bars of iron
bearing against the angles respectively of the zig-zag bars to be joined. Clips.
of a rectangular form are passed over the two angles of the zig-zag bars to be
joined, and through holes in the said clips the tines of the harrow are driven;

page_text: the driving of the said tines not only fixes them in the holes in the clips, but
bearing against the parallel bars binds them tightly against the angles of the
zig-zag bars, and thus secures the whole together. The clips through which
the tines are driven consist of two pieces of flat iron bent twice at right
angles, so as to form three sides of a square. Each half clip has a hole made
in its opposite sides of a size proper to receive the tine. In putting them over
the angles of the zig-zag bars the open side of one half clip is passed over
one angle, and the open side of the other half clip over the other angle of the
zig-zag bars, the upper and lower sides of the half clips lying parallel to one
another. Instead of double clips single clips may be used. In this case the
upper and lower sides of the clip are made longer than when double clips are
used, and besides the holes in the said sides for the passage of the tine, two
other holes near the ends of the said sides are made for the reception of a
wedge or key. In putting together the harrow with single clips the clip is
passed over the angles of the zig-zag bars, and the key or wedge driven
through, and the tine is also passed through the middle of the clip, and
between the parallel bars. The key or wedge constitutes a fourth and move-
able side to the clip, and acts essentially in the same way as the second clip
in the first described arrangement. Although I prefer to use two parallel
bars as described between two of the zig-zag bars to be joined together, yet
one only of the said parallel bars may be employed, and in light harrows the
said parallel bars may both be dispensed with.
