GEORGE W. LEE, OF GRANBURY, TEXAS.
COMBINED PLOW AND HARROW.
SPECIFICATION forming part of Letters Patent No. 495,895, dated April 18, 1898.
Application filed August 31, 1892. Serial No, 444,671, (No model.)To al whom it may concern:
Be it known that I, GEORGE W. LEE, a citi-
zen of the United States, residing at Gran-
bury, in the county of Hood and State of
5 Texas, have invented a new and useful Com-
bined Plow and Harrow, of which the follow-
ing is a specification.
My invention relates to a combined plow
and harrow, adapted to be used simultane-
ro ously or detached and used independently,
as desired, the object in view being to pro-
vide a simple, cheap, and effective machine,
capable of adjustment to suit the require-
ments of different soils and different condi-
15 tions of the soil.
Further objects and advantages will appear
in the following description, and the novel
features will be particularly pointed out in
the appended claim.
20 In the drawings, Figure 1 is a perspective
view of a cultivator embodying my improve-
ments. Fig. 2 is a plan view showing in
dotted lines an extended adjustment of the
frame.
25 A represents the central beam, which forms
a part of the draft-beam, and carries the han-
dles, B B, and the colter standard, C.
D E designate, respectively, the rearwardly
divergent side-beams, arranged upon oppo-
30 site sides of the central beam and capable of
angular adjustment in relation thereto. The
front ends of the side-beams are provided
with vertical eyes, F F, which engage verti-
cal pivot-pins, G G, attached to and carried
35 by the central or main-beam, whereby the
front ends of the side-beams are held close to
the sides of the main-beam while their rear
ends are capable of being adjusted toward or
from the main-beam, as shown by the dotted
40 lines in Fig. 2. To the rear ends of the side-
beams are pivotally connected, by means of
vertical bolts, H H, the adjusting straps, K K,
the inner ends of said straps being longi-
tudinally slotted, as shown at kc k, to receive
45 the vertical adjusting bolt, L, whereby by
tightening said bolt the side-beams may be
locked and held rigidly at any desired deflec-
tion from the line of the main-beam.
To the side-beam, D, are secured the plow-
50 standards, M M, which may be of any ap-
proved design, either rigid or of the spring-
tooth variety, the ordinary rigid form being
shown in the drawings, and to the beam E
are secured the harrow-teeth, N N, which,
55 also, may be of any approved kind.By loosening the adjusting bolt, by which
the inner, overlapping ends of the adjusting
straps are secured to the -main-beam, either
or both of the side-beams may be detached
from the main-beam, so as to adapt the de- 6o
vice for use as a side-plow or a side-harrow,
or, (if both side-beams are removed and the
plow standards are arranged upon the main
beam) as an ordinary plow. The eyes at the
front ends of the side-beams enable the parts 65
to be readily detached for the purpose of
adapting the cultivator to the character of
the soil and the kind of work desired.
To prevent the rising and accidental de-
tachment of the side-beams from the main 70o
beam, I provide the main-beam with a hori-
zontal perforation, which registers with simi-
lar perforations, m, in the side-beams, and
through these perforations I pass a retaining
pin, M. This pin is removable to permit the 75
detachment of the side-beams, and while in
place it prevents the vertical movement or
vibration of the same. The retaining pin is
arranged near the pivotal points of the side-
beams, and therefore, when the pin is in place 8o
it does not interfere with the lateral adjust-
ment of either or both of the side-beams.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent of the United States, is- 85
In a cultivator, the combination with the
central main-beam, of vertical pivot-pins at-
tached to the sides of the main-beam near its
front end, the rearwardly divergent side beams
provided at their front ends with eyes pivot- go
ally mounted upon said pivot-pins, the slotted
straps pivotally connected to the rear ends of
the side-beams and adjustably connected at
their overlapping innerends tothe main-beam,
and a horizontal retaining pin, fitting in reg- 95
istering perforations in the side and main
beams adjacent to the front or pivoted ends
of the former, to prevent the accidental de-
tachment of the side-beams from the main-
beam without interfering with the relative ioo
adjustment of such parts, substantially as
specified.
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in
the presence of two witnesses.
GEORGE W. LEE.
