HENRY THOMAS SMITH, OF DE LEON, TEXAS.
SIDE HARROW FOR CULTIVATORS.
Specification of Letters Patent.
Patented Oct. 25, 1910.
Application filed December 3G, 1909. Serial No. 535,612.
To all whom it may concern:
Be it known that IL HENRY THOMAS
SmiTT-L, a citizen of the United States, re-
siding at De Leon, in the county of Co-
5 manche and State of Texas, have invented
certain new and useful Improvements in
Side Harrows for Cultivators, of which the
following is a specification.
My invention relates to new and useful
10 improvements in side harrows for cultiva-
tors. Its object is to provide a small harrow
which may be adjusted to both of the inner
plow feet of a cultivator in place of the plow
ordinarily carried by said plow feet.
15 A further object is to provide a side har-
row for a cultivator, the teeth of which har-
row may be adjusted vertically or at various
Finally the object of the invention is to
20 provide a device of the character described,
that will be strong, durable, simple and effi-
cient, and comparatively easy to construct
and also one, the parts of which will not
be likely to get out of working order.
25 With these and various other objects in
view, my invention has relation to certain
novel features of construction and operation,
an example of which is described in the fol-
lowing specification, and illustrated in the
30 accompanying drawing, wherein;
Figure 1 is a rear perspective view of a
cultivator, having the herein described side
harrow attached to the beams thereof. Figs.
2 and 3 are front and top views respectively
35 of the harrow. Fig. 4 is a detail view of the
spring used to clamp the harrow to a plow
foot of the cultivator, the view being taken
in the direction indicated by the arrow in
40 Referring now more particularly to the
drawing wherein like numerals of reference
designate similar parts in all the figures, the
numeral 1 denotes the transporting wheels
of the cultivator, and 2 the U-shaped axle
45 upon which said wheels are mounted.
The numeral 3 designates the cultivator
beams extending rearwardly from the axle,
and provided with plow feet 4. Upon the
outer plow feet, are shown a pair of ordi-
50 nary plows 4a, and upon the inner plow feet,
a pair of the herein described side harrows
are shown mounted.
Each side harrow consists of a horizontal
bar 5 to which are clamped a- plurality of
55 harrow teeth 6, the clamping means con-
sisting of a plate 7 approximately U-shaped
in horizontal cross section, pivoted upon a
bolt 8 at one side, and provided with a plu-
rality of bolt holes 9 at the other side so that
the teeth may be attached at various angles 60
with the vertical. At its middle, the bar 5 is
provided with an indented portion 10
against which the plow foot is adapted to
be clamped, a slot 11 being provided in said
portion to receive the clamping bolt. The 65
resilient bar 12 which is attached at the rear'
of one extremity of the bar 5 extends rear-
wardly at an angle approximately equal to
that of the indented portion 10 of the bar,
and is adapted to be clamped behind the 70
.plow foot, a slot 13 being provided to receive
the clamping bolt 14.
It will be seen from the above description
that a side harrow is provided, in which the
teeth may be adjusted vertically or may be 75.
adjusted at an angle with the vertical to-
ward either extremity of the bar 5. It is in-
tended that the harrow when in position on
the plow feet will form an angle of approxi-
mately 45 degrees with the direction of 80
travel. However this angle is also capable
of some adjustment.
It is obvious that the number of harrow
teeth may be varied, and that various de-
tails of the construction may be modified 85
without departing from the spirit or sacri-
ficing the advantages of the invention. I
therefore reserve the right to make such
changes and alterations in said device, as
fairly come with in the scope of the follow- 90
What I claim is:
A side harrow for cultivators consist-
ing of a bar having an indented portion at
its center, containing a slot longitudinal 95
with the bar, a plurality of harrow teeth
clamped to said bar, and a resilient bar se-
cured to one extremity of the bar at the
rear thereof and extending rearwardly and
toward the center of the bar, a slot being 100
provided at the other extremity of said re-
silient bar, and attaching means engaged in
In testimony whereof I have signed my
name to this specification in the presence of 105
two subscribing witnesses.
