UNITED STATES PATENT OFFICE,
MELICHAR PROHASKA, OF CISTERN, TEXAS.
WEEDING-PLOW.Specification of Letters Patent.
Patented Nov. 27, 1917.
Application filed March 29, 1917. Serial No. 158,278.
To all whom it may concern:
Be it known that I, MELIOHAR PROHASKA,
a citizen of the United States, residing at
Cistern, in the county of Fayette and State
5 of Texas, have invented certain new and
useful Improvements in Weeding-Plows, of
which the following is a specification.
This invention relates to certain new and
useful improvements in weeding plows.
10 The primary object of the invention is
the provision of a plow especially adapted
for employment with corn and cotton for
removing weeds and mellowing the ground
thereby assisting the growth of the crop.
15 A further object of the device is the pro-
vision of a weeder adapted for the culti-
vation of crops arranged in rows growing
in a field, the structure being simple and in-
expensive to manufacture and possessing
20 great strength and durability.
With these general objects in view and
others that will appear as the nature of the
invention is better understood, the same con-
sists in the novel construction, combination
25 and arrangement of parts hereinafter fully
described, illustrated in the accompanying
drawings and pointed out in the appended
claim.
In the drawings forming a part of this
30 application and in which like numerals
refer to corresponding parts throughout
the several views-
Figure 1 is a side elevation of the device.
Fig. 2 is a top plan view thereof.
g5 Fig. 3 is a vertical transverse sectional
view taken upon line III-III of Fig. 1 in
the direction indicated by the arrows.
Fig. 4 is a detail longitudinal sectional
vertical central view taken upon line
1o IV-IV of Fig. 2.
Fig. 5 is a transverse oblique sectional
view taken upon line V-V of Fig. 1.
Fig. 6 is a perspective view of the free
end portion of one of the plow beams, and,
15 Fig. 7 is a perspective view of one of the
plow blades.
The device broadly consists of a main
draft beam 10 having separate hand con-
trolled plows designated generally as 11 de-
60 tachably connected to the opposite sides
thereof, a supporting wheel 12 being ad-
justably arranged at the rear end of the
draft beam while a rearwardly projecting
handle 13 is provided upon the rear end of
55 each of the plows 11, it being understood
that draft animals are attached to a usualform of clevis 14 for propelling the device
forwardly.
The wheel 12 is mounted in the. forked
lower end of a standard 15 adjustably ar- 60
ranged through the draft beam 10 and
through bearing plates 16 on the upper and
lower faces of said beam at the rear end
thereof, the said draft beam being main-
tained at the desired elevation on the stand- 65
arl by the means of pins 17 extending
through perforations 18 in the said stand-
ard above and below the draft beam.
Each of the plows 11 is of the same con-
struction but of opposite arrangement, being 70
suspended from a plow beam 19 provided
with a metal loop 20 at its forward end for
detachably positioning over a laterally pro-
jecting hook 21 carried at the forward end
of the plow beam 19 and secured thereto by 75
means of an attaching plate 22, a form of
link or double hook 23 being inclosed with-
in a central transverse groove or depression
24 of the plate 22, thereby arranging a hook
21 at each side of the beam 10. 80
Each plow beam 19 is provided with a
plow or weeding blade 25 in the form of an
elongated shovel having a tang 26 secured
to the lower end of a curved standard 27
arranged with perforations 28 therethrough 85
whereby the standard is secured at the de-
sired vertical adjustment upon a project-
ing bolt 29 and held by a nut 30, an angular
stop plate 31 being attached to the outer
face of the beam 19 for positioning the 90
standard 27 at the desired inclination for
operatively arranging the blades 25 with
respect to the ground or soil 32 being oper-
ated upon. The handle 13 is secured as at
33 to the plow beam near the rear end there- 95
of, a brace or strut 34 being arranged be-
tween the handle 13 and the aforementioned
bolt 29.
The beams of the plows 11 being detach-
ably connected with the hooks 21 with the 100
blades 25 of the plows resting upon the
ground 32, said beams will be positioned
upon opposite sides of the wheel 12 and the
draft-beam be maintained. A rod 35 is
transversely arranged through the draft 105
beam 10 above the normal level of the plow
beam 19 for limiting the upward movement
of the plows 11.
The pivotal connection of the plows with
the hooks 21 permits the operator to spread 110
the rear ends of the plow beams 19 or move
them inwardly so that they lie against the1,248,010.
