JAMES W. JONES AND GEURGE H. TUCKER, OF WINTERS, TEXAS.
HARROW ATTACHMENT.1,083,364.
Specification of Letters Patent.
Patented Jan. 6,1914.
Application filed December 16, 1911. Serial No. 666,092.
To all whom it may concern:
Be it known that we, JAMES W. JoNEs
and GEORGE H. TUCKER, citizens of the
United States, residing at Winters, in the
5 county of Runnels and State of Texas, have
invented certain new and useful Improve-.
ments in Harrow Attachments, of which the
following is a specification.
Our invention relates to new and useful
10 improvements in harrow attachments for
cultivators. Its object is to provide a har-
row attachment for cultivators, comprising
two similar members, one of which is adapt-
ed to be attached to each cultivator beam,
15 thus making it possible to employ the culti-
vator mechanism for adjusting the beams,
to regulate the relative positions of the two
harrow members.
Another object is to provide a harrow,
20 consisting of two members diverging rear-
wardly from their point of support, and
adapted to be adjusted with regard to their
angle of divergence, thus making it possible
to regulate the area of ground acted upon
25 by the harrow.
A further object consists in the provision
of a means for elevating the rear portion of
the harrow, thus regulating the depth to
which the teeth penetrate the ground.
so A still further object of the invention lies
in the provision of a convenient. means by
which the teeth of the harrow may be
clamped in the frame formed by said di-
vergent members.
35 Finally the object of the invention is to
provide a harrow of strong and simple con-
struction, the parts of which may be quickly
assembled or taken apart, and which will
not be likely to loosen in use or to be readily
40 damaged.
With these and various other objects in
view, our invention has relation to certain
novel features of the construction and op-
eration, an example of which is described in
45 the following specification and illustrated
in the accompanying drawing, wherein:
Figure 1 is a plan view showing the har-
row attachment, in which are embodied the
novel features constituting the present in-
50 vention. Fig. 2 is a view of the same in
side elevation. Figs. 3 and 4 are perspec-
tive detail views respectively showing two
clamping members which serve to secure
the harrow teeth to a suitable frame. Fig.
55 5 is a detail view showing a standard adapt-
ed to have its upper end clamped rigidly tothe cultivator beam and its lower end piv-
otally receive the harrow attachment.
Referring now more particularly to the
drawing, wherein like reference characters
designate similar parts in all the figures,
the letter "A" denotes a cultivator beam, of
any common and well-known type, to which
beam is rigidly clamped an upright or ver-
tical standard "B ".
The clamping means employed may be
any of those now in common use to furnish
means for rigidly supporting a plow stand-
ard from a cultivator beam, such as the well-
known type shown in the drawing. The
lower end of the rod " B " carries a pair of
spaced brackets ''"D ", in which brackets is
journaled a short transverse spindle, " E ",
having its extremities projecting slightly
beyond said brackets and horizontally flat-
tened. . The flattened extremities of the
spindle "E " furnish pivotal supports for a
pair of rearwardly extending divergent
beams " F ", each of which beams serves to
support a plurality of. equidistant vertical.
harrow teeth " G ". These harrow teeth will
preferably be pointed at one extremity, the
other extremity. being slightly curved form-
ing what is commonly known as a " duck-
bill."
Each harrow tooth is adapted to be se-
cured to its correlated beam " F " by a pair
of clamping members " H" and "J ", the
former being bent to form a right angle.
One portion of this angular member, which
is adapted to project beneath the correlated
beam, is provided with an aperture " K "
through which the tooth " G " may be
passed. The other portion of the angular
member " H " will occupy a vertical position
contiguous with the outer surface of the
beam, and is provided with a small aperture
" L " at its upper extremity adapted to re-
ceive a threaded stud "M" which projects
from one extremity of the member " J ".
The other extremity of the member J is
provided with a circular aperture " D "
adapted to receive the harrow tooth. When
the two members H. and J. occupy their
proper positions relative to each other and
to the beam F, the apertures P and K will
be in vertical alinement, and the stud M will
project through the aperture L, a nut being
provided upon the extremity of said stud
contiguous with the vertical portion of the
member H. It is thus apparent that the
members H and J in conjunction may be60
