FRIEDRICH BRAUNE, OF. CLIFTON, TEXAS.CULTIVATOR.
Specification of Letters Patent. Patented Sept. 28, 1915.
Application filed March 31, 1913. Serial No. 757,914.To all whom it may concern:
Be it known that I, FRIEDRICH BRAUNE, a
citizen of United States, residing at Clif-
ton, in the county of Bosque and State of
5 Texas, have invented certain new and use-
ful Improvements in Cultivators, of which
the following is a specification.
This invention relates to improvements in
cultivators and it contemplates the pro-
10 vision of such a machine wherein each
shovel standard is so mounted upon a longi-
tudinal shaft as to be capable of oscilla-
tion toward either side of the machine there-
by making it possible to vary the distance
15 between the shovels; the shovel standards
are also capable of vertical adjustment
thereby regulating the depth of shovel pene-
tration and said shovel standards are also
capable of oscillation in a plane at right
20 angles to the axle of the machine thereby
effecting an almost vertical or as oblique or
angular a shovel penetration as may be de-
sired.
With the foregoing and other objects in
25 view the invention consists in the combi-
nation and arrangement of parts to be here-
inafter fully described in the following
specification, pointed out in the claims and
illustrated in the accompanying drawings
3o which form a part of the specification and
in which-
Figure 1 is a fragmental side elevation
of my invention or cultivator; Fig. 2 is a
fragmental plan view thereof; Fig. 3 is a
35 rear elevation of the same; Fig. 4 is a sec-
tion taken on the line 4-4 of Fig. 3.
Like reference characters indicate cor-
responding parts throughout the several
views.
40 1, 1 are the traction wheels of my culti-
vator mounted upon an axle 2; 3 is the
tongue and 4 the beam that carries the seat
5. To the axle 2 a plurality of couplings
6 are fixed that pivotally carry one end of
45 longitudinal beams 7 which terminate at
their opposite extremities in pivots 8 where-
on bearings. 9 are mounted that are formed
integral with segments 10 from which seg-
ments integral arms 11 are projected and to
50 the free extremities of which arms springs
12 are secured that are fastened to the seat
5. Each arm 11 is apertured for passage
therethrough of an adjusting screw 13 which
engages the seat 5 to regulate the tension of
55 spring 12 upon said arm.
The bearing 9 is formed with a shaft-prowjection 14 which is formed with an annular
recess at 15 for the reception of one end of
a screw 16 carried by a sleeve 17 .disposed
upon said shaft 14. The sleeve 17 is formed 60
with integral oppositely disposed guide
sleeves 18, 18 disposed in a plane at right
angles to the plane of the sleeve 17 and in
said guide sleeves the shovel standard 19,
square in cross section, is arranged. Said 65
shovel standard is formed with a plurality
of apertures 20 to receive an eye-bolt 22
upon which a spring 23 is disposed which
abuts the bolt at one extremity and a cas-
ing 24 at the opposite extremity, said cas- 70
ing being apertured for passage of the eye-
bolt and having its angular extremities 25
bolted to the guide sleeves 18. It is readily
seen that by means of the pin 22 and its
connections the shovel standard 19 may be 75
adjusted within the guide sleeves and locked
in such position.
26 is a support made integral with sleeve
17 and bifurcated at its upper extremity for
the reception of a dog 27 adapted for en- 80
gagement at one extremity with the segment
10 while the opposite extremity is engaged
by a spring 28 fastened to the said sleeve 17.
29 is another segment made integral with
the sleeve 17 and disposed in a plane at 85
right angles to the plane of the segment 10
and adapted for engagement with an eye-
bolt 30 that extends through a casing 31 se-
cured to a guide piece 32 carried by the
beam 7 and upon the body of said eye-bolt a 90
spring 33 is disposed to retain the bolt in
its set or adjusted position. The shovel
standards are provided with shovels 34 and
also with foot levers 35 by means of which
the shovels may be retained at a set depth in 95
the ground against the tension of the
spring 28.
Operation: If it is desired to increase or
diminish the shovel penetration the eye-
bolt 22 is drawn out of engagement with the loo
shovel standard 19 and the said standard
manually raised or lowered as desired and
the eye-bolt then reset in the alined aper-
ture in said shovel standard. If it is de-
sired to oscillate one or more shovel stand- 1o5
ards to either side of the machine thereby
increasing or diminishing the space between
such standards the eye-bolt 30 is withdrawn
from engagement with the segment 29 and
the bearing 9 oscillated on the pivot 8 and 110
then by means of eye-bolt 30 again locked
in engagement with segment 29. If it is de-1,154,841.
