made to clamp the harrow tooth securely in
place at any desired elevation, with either
of its two extremities uppermost.
A description will now be given of the
5 means employed to secure adjustment of the
angle formed between the two converging
beams F. A bar N containing a plurality of
small equidistant apertures 0 is transversely
extended beneath the center portions of the
10 two beams F. The end portions of the bar
N are received in slots formed between the
undersides of the beams F and members R
rigidly secured to said beams by bolts S.
The members R serve to prevent any verti-
15 cal motion of the bar N relative to the beam,
and also to prevent any motion of said bar
in a direction longitudinal with said beams.
In order to prevent a transverse motion
between the bar and the beams after the lat-
20 ter have been adjusted at the proper angle,
a U shaped bolt T is made to establish an en-
gagement between each beam and the bar,
said bolt being mounted in an inverted posi-
tion with its extremities extended down-
25 ward through two of the apertures 0. It
is apparent that the harrow beams are held
in a fixed relation to each other when the
bolts T are thus made to establish a connec-
tion between said beams and the bar N. The
so angle of divergence between the two beams
may be readily adjusted by removing the
bolts T. and replacing them each in a dif-
ferent pair of holes 0, after the beams have
been shifted to the proper angle.
35 The means provided for producing a
slight vertical adjustment of the rear por-
tion of the harrow comprises a bar U, hav-
ing one of its extremities pivotally connected
to the centers of the bar N. by means of a
40 U bolt V., said bar being extended for-
wardly at an upward inclination, and hav-
ing its upper extremity entering a slot W,
provided for that purpose in the upper endof the standard B. Said extremity of the
bar U is curved slightly downward, and is 45
provided with a number of apertures Y to
receive the cotter pin Z by which pivotal
connection is established between the mem-
bers U and B. Obviously, the rear end of
the barrow may be adjusted through slight 50
variations of height according to which of
the apertures Y is made to receive the pin Z.
From the foregoing disclosure in conjunc-
tion with the accompanying drawing, it will
be readily apparent that a harrow of the 55
character described is adapted to fulfil all
the necessary requirements of such a device.
The invention is presented as including
all such changes and modifications as are in-
cluded within the scope of the following 60
claim.
What we claim is:-
In a device of the character described, the
combination with a vertical standard, of a
pair of spaced brackets carried by the lower 65
extremity of said standard, a spindle jour-
naled in said bracket, a pair of divergent
.horizontal beams having their adjacent
extremities pivoted upon the extremi-
ties of said spindle, the pivotal connec- 70
tion being such as to permit a swinging dis-
placement of the beams to or from each
other, means establishing a rigid relation be-
tween the middle portions of the bars, a plu-
rality of harrow teeth supported by each of 75
said beams, and means for holding the beams
in various positions of angular displacement
about their pivoted forward extremities.
In testimony whereof we have signed our
names to this specification in the presence of 8o
two subscribing witnesses.
