GEORGE D. GRIFFICE, OF BIG SPRING, TEXAS.
CULTIVATOR.1,237,508.
Specification of Letters patent.
Patented Aug. 21, 191d.
Application filed October 16, 1916. Serial No. 125,909.
To all whom it may concern:
Be it known that I, GEORGE D. GRIFFICE, a
citizen of the United States, residing at Big
Spring, in the county of Howard and State
5 of Texas, have invented certain new and
useful Improvements in Cultivators, of
which the following is a specification, refer-
ence being had to the accompanying draw-
ings.
10 This invention relates to certain improve-
ments in cultivators and it is an object of
the invention to provide novel and im-
proved means whereby a cultivator of con-
ventional construction may be readily and
15 conveniently converted into a surface culti-
vator.
It is also an object of the invention to
provide a novel and improved attachment
for a cultivator whereby an ordinary culti-
20 vator may be employed.as a surface culti-
vator and wherein the cutting blade is ef-
fectively held against displacement after
the attachment has been applied to a beam.
The invention also has for an object to
25 provide novel and improved means whereby
the beams of a cultivator may be effectively
held against relative or lateral displace-
ment.
The invention consists in the details of
30 construction and in the combination and ar-
rangement of the several parts of my. im-
proved cultivator whereby certain impor-
tant advantages are attained and the device
is rendered simpler, less expensive and oth-
35 erwise more convenient and advantageous
for use, all as will be hereinafter more fully
set forth.
The novel features of the invention will
hereinafter be definitely claimed.
40 In order that my invention may be the bet-
ter understood, I will now proceed to de-
scribe the same with reference to the ac-
companying drawings, wherein-
Figure 1 is a view partly in elevation and
45 partly in section illustrating an attachment
constructed in accordance with an embodi-
ment of my invention and in applied posi-
tion;
Fig. 2 is a view in side elevation of the
50 attachment as herein embodied, the coacting
beam of a cultivator being shown in frag-
ment;
Fig. 3 is a view in top plan of the device
as disclosed in Fig. 1;Fig. 4 is a sectional view taken substan- 55
tially on the line 4-4 of Fig. 2;
Fig. 5 is a fragmentary view partly in
elevation and partly in section illustrating
a slightly modified form of invention;
Fig. 6 is a fragmentary view in elevation 60
illustrating a still further modified embodi-
ment of my invention; and
Fig. 7 is a fragmentary view in end ele-
vation of the device as disclosed in Fig. 6.
As disclosed in Figs. 1 to 3 of the ac- 65
companying drawings, B denote cultivator
side beams of conventional construction and
with each of which is operatively engaged
a casting C for suitably securing to said
beam B the shank S of a conventional cul- 70
tivator plow and which plow is omitted in
the accompanying drawings.
T denotes a table preferably rectangular
in top plan and which is provided with the
depending split barrel 1 through which the 75
beam B is disposed and coacting with t.he
barrel 1 and the table T are the clamping
members 2 of conventional type and which
serve to effectively hold the table T to the
beam B, as is thought to be clearly apparent so
to those skilled in the art .to which my in-
vention appertains, and as is particularly
illustrated in Figs. 2 and 3, the table T is
positioned in predetermined spaced relation
relative to the casting C. It is not essential 85
however that the table T and the barrel 1 be
integrally connected as the table may be
separate as is disclosed in Fig. 5 of the ac-
companying drawings and wherein the
table T' is independent of the casting or 90
barrel 1a but is effectively held thereto
through the medium of the clamping mem-
ber 2a. Integrally connected with the barrel
1 is a second barrel 3 arranged at substan-
tially right angles to the barrel 1 and table 95
T and through which is adapted to be di-
rected the supplemental shank S'.
An intermediate portion of the barrel 3
is enlarged, as at 4, and within said en-
larged portion 4 is positioned the eye mem- 100
ber 5 through which the shank S' is di-
rected, and said eye is provided with the
radially disposed threaded shank 6 extend-
ing exteriorly of the barrel 3 or more par-
ticularly the enlarged portion 4 thereof 105
and has coacting with its extended portion
the clamping nut 7 whereby it will be per-
ceived that the shank S' may be effectively
