Improvements in Harrows.
We, JULIUS GERTH, of Gössnitz, and ARTHUR SCHWARZENBERG, of
Dennheritz, both in the Kingdom of Saxony, German Empire, Agricultural
Machine Manufacturers 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 :-
The present invention relates to harrows, and cousists in providing the same
with an adjusting mechanism for the spikes, by means of which the said spikes may
be adjusted simultaneously in the vertical plane, that is to say, the same may
either be arranged at right angles to the ground, or at another angle to the same,
as may appear advantageous. The invention further consists in making the said
harrow laterally uneven or zig zag, the two sides being parallel to each other, but
each bent in a zig zag shape as hereinafter more particularly described.
And in order to make the present Specification more easily intelligible, reference
is had to the accompanying drawing in which similar letters denote similar parts
throughout the several views:-Fig. 1 being a side elevation of the improved
harrow, and Fig. 2 a plan of the same.
The spikes zz are rigidly attached to the horizontal bars 9999, which are
pivoted to the zig zag side bars at a a, b b, c c, d d, ee, respectively. These bars 99
are provided with upwardly extending arms q¹ q¹q' which are connected up by
means of a coupling rail or bar S pivotally attached to a lever h mounted rigidly
on the rear horizontal bar g of the harrow. Mounted on the harrow at one side by
means of the stays s¹s and at the other direct to the rear bar is a notched
segment s, over which the lever plays and by means of which the same is retained
in any desired position by means of its spring pin which is adapted to engage in the
notches of the segment and may be operated from the lever handle by means of
the lever 1.
The spikes are arranged on the horizontal bars qq in such manner that they all
lie in different vertical planes so that no one of the same will follow the one in front
of it, but each will form a separate furrow. The object of making the sides of the
harrow zig zag is that it enables several harrows to be coupled alongside each other,
each harrow forming a continuation of the one before it.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is performed we declare that what we
claim is :-
(1.) A harrow having zig zag lateral bars running parallel to each other and
having spikes mounted on horizontal bars, said horizontal bars being pivotally
attached to the said lateral bars, and means for coupling up the horizontal bars and
for adjusting the positions of the spikes substantially as described.
(2.) In a harrow the combination of zig zag lateral bars parallel to each other,
horizontal cross bars to connect the same, said cross bars being pivotally connected
to said lateral bars, spikes arranged on said cross bars as specified, upwardly
extending arms to said bars, a connecting rod to connect up the said arms, and a
lever pivoted to the rear of the harrow and to the coupling rod a notched segment

page_text: to guide said lever and a spring pin to said lever to engage the notches of the said
segment and retain the lever in position in the manner and for the purpose
substantially as described and shown.
