JOHN R. WEST, OF PALMER, TEXAS.
CULTIVATOR.Specification of Letters Patent.
Patented Jan. 31,"1911.
Application filed March 2. 1910. Serial No. 546,852.
To all whom it.may concern:
Be it known that I, JOHN R. WEST, a citi-
zen of the United States, residing at Palmer,
in the county of Ellis and State of Texas,
5 have invented certain new and useful Im-
provements in Cultivators; of which the fol-
lowing is a specification, reference being had
to the accompanying drawings.
My invention relates to improvements in
10 cultivators, and more particularly to means
for holding or carrying the standards of
cultivator shovels, plows or the like and ad-
justing them toward and from each other.
One object of the invention is to provide
15 improved means for mounting and adjusting
shovel or plow carrying standards.
Another object of the invention is to pro-
vide a device of this character which may be
applied to the beams of ordinary wheeled cul-
20 tivators, whereby two rows of plants may be
effectively plowed or cultivated, and where-
by the cultivator may be used either as a
riding or walking cultivator.
With the above and other objects in view,
25 the invention consists of the novel construc-
tion, combination and arrangement of parts,
hereinafter fully described and claimed, and
illustrated in the accompanying drawings in
which:
30 Figure 1 is a side elevation of one em-
bodiment of my invention applied to a
wheeled cultivator of ordinary construction;
Fig. 2 is a top plan view, the cultivator be-
ing indicated in dotted lines; Fig. 3 is an en-
35 larged plan view of one of the carriers for
holding and adjusting cultivator shovel
standards; Fig. 4 is a side elevation of the
same partly in section; Fig. 5 is a vertical
transverse section taken on the plane indi-
40 cated by the line 5-5 in Fig. 4; Fig. 6 is a
detail vertical section taken on the plane in-
dicated by the line 6-6 in Fig. 3; and Figs.
7 to 11 inclusive are detail views of parts.
In the drawings A denotes an ordinary
45 wheeled cultivator having the usual rear-
wardly extending, horizontal. beams B
loosely mounted at their. forward ends.
My improved holders or_ carriers for the
standards of cultivator or plow shovels are
50 mounted on the rear portions of the beams
B, and each .comprises a transverse body 1
made preferably hollow or with hollow ends
to receive slides 2 on the outer extremities of
. which are standards 3. The latter may beof any form andconstruction and may carry 55
cultivator shovels or plows 4 or other earth-
working devices; and they are adjusted to-
ward and from each other by shifting the
slides 2 as presently explained. A third
standard 5 is provided at the center of the 60
rear portion of the body or holder 1 and car-
ries a suitable shovel or earth-working de-
vice 6 so that the shovels 4, 6, are disposed in
triangular relation and' plow the ground be-
tween two rows of plants, the shovel 6 work- 65
ing in the center of the furrow, while the
shovels 4 work close to the rows of plants.
By arranging two of the holders or carriers
on the beams B of the cultivator A it will
be seen that as the latter is drawn over 70
one row of plants it will cultivate in effect
two rows.
The slides 2 are simultaneously shifted to-
ward and from each other within the body
1 by means of two pairs of toggle links 7, 8, 75
which links have their adjacent ends over-
lapping and arranged on anti - friction
sleeves 9 on upright pivot pins or bolts 10,
which latter pass vertically through the
slides 2, a ud also through longitudinal slots 80
1.1 in the top and bottom of the body 1. The
forward ends of the link 7 are overlapped
and arranged on an anti-friction sleeve 12,
to which latter is secured by means of a
bolt or fastening 13 an angular metal clip 85
14. The rear ends of the .links 8 are like-
wise overlapped and engaged with an anti-
friction .sleeve 15 to which is connected by
means of the bolt or fastening 16 an angular
metal clip 17 similar to the clip 14. The 90
pivot or bolt 16 has its lower end fixed in a
slide 18 in the form of a block or plate hav-
ing its edges engaged with undercut -or
grooved guide strips 19 secured to the top
and i-ear portion of the body 1. The slide 95
18 it will be noted will guide the pivot 16
in its forward and rearward movement and
thereby cause the pivots 10, and hence the
slides 2 to be moved simultaneously in oppo-
site directions and to the same extent. The 100
clips 14, 17, have connected to them shifting
rods 20, 21, the forward ends of which latter
are pivotally connected to an operating lever
22 which may be fulerumed on any suitable
support. The lever 22, however, is prefer- 105
ably mounted on an upright bracket 23
clamped to one of the beams B and the rods
20, 21, are pivotally connected to it as shown982,912.
