RICHARD D. LOIKA AND CHARLES E. LOIKA, OF BALLINGER, TEXAS.
PLOW.Specification of Letters Patent.
Patented Nov. 25,1913.
Application filed March 21, 1912. Serial No. 685,209.
To all whom it may concern:
Be it known that we, RICHARD D. LOIKA
and CIIALEs E. LoIKA, citizens of the
United States, residing at Ballinger, in the
5 county of Runnels, State of Texas, have in-
vented certain new and useful Improve-
ments in Plows; and we do hereby declare
the following to be a full, clear, and exact
description of the invention, such as will
10 enable others skilled in the art to which it
appertains to make and use the same.
This invention has particular reference
to plows of the lister type.
Primarily, the object of this invention is
15 to province a novel and simple plow struc-
ture which permits of the detachment of
the mold boards of the plow for nakino a
low bed or for making a high bed especially
when the grass and weeds in a field are con-
20 siderably high.
Another and important object of the in-
vention consists in rendering the parts of
the plow readily attachable and detachable
and in which the handles of the plow may
25 be conveniently attached to the mold boards
or to the frog when the wings are removed,
the plow being of novel formation and hav-
ing a stalk distributer attached to the beam
thereof so as to push the stalks cut of the
30 way during the advance of the plow.
With the above and other objects in view,
the invention consists in certain combina-
tions and arrangements of parts to be here-
inafter more fully described, claimed and
35 illustrated in the accompanying drawing
forming part of this application, in which:
Figure 1. is a longitudinal sectional view
of the plow. Fig. 2. is a perspective view
of the plow with the mold boards removed
40 and the handles attached to the frog of the
plow, for use in making low beds. Fig. 3. is
an inverted perspective view of the frog
and its beam attaching ear and also with the
guide bars connected thereto.
45 Referring more specifically to the draw-
ings in which like characters designate simi-
lar parts throughout the several views, the
numeral 10 designates the beam of the plow
which is preferably of metal, the same hav-
50 ing its lower end or its curved rear end at-
tached to an angular frog 11. This frog
is formed preferably of cast metal and has
its side portions 12 enlarged laterally rear-
wardly of their forward ends as shown at
55 13 and terminating in a tapered forward end
portion 14 while the beam 10 is secured rear-wardly of the frog 11 through the medium
of an apertured ear or attaching bracket 15
which is provided with a flanged portion 16
which is secured to the inner face of the 60
frog vertically of its angular portion and
near its rear and upper edge.
A point 17 is mounted on the forward end
of the frog 11 and has a pair of shares or
share blades 18 and 19 extending rearwardly 65
and outwardly to form an approximately V-
shaped notch in the rear edge of the point
along the edges of which, said point is re-
movably attached to the side portions of the
frog. Both of the wings 18 and 19 form a 70
point of extreme width being 24 inches wide
so as to produce a cut of 24 inches of ground
to assist in its cutting operation and the rear
edges of the shares are also beveled as shown
at 20 to permit the proper distribution of 75
the elevated soil during the advancement of
the plow.
In addition to the point 17 and its shares
18, the mold-board of the plow is formed of
opposite mold boards or. double mold boards 80
21 having their inner edges meeting at the
angular portion of the frog and bent in con-
caved form to conform to the curvature of
the frog, while the lower ends of the mold
boards 21 engage in the notch at the rear 85
end of the point 17 and are secured along
said ends to the frog in a similar manner
as the plow point is secured thereto. The
mold boards 21 each have their upper por-
tions provided with outwardly and rear- 90
wardly extending portions or lateral exten-
sions 22 which preferably have their rear
ends rounded, these. extensions serving to
regulate the height of the bed formed by the
plow. Also secured to the angular portion 95
of the frog 11 beneath the attaching bracket
15 is an attaching bracket or plate 23 to
which the lower rear end of the beam 10 is
secured in connection with a horizontal rear-
wardly extending guide bar 24 adapted to 100
engage the ground rearwardly of the plow
point for guiding the same and determining
the proper depth of the furrow. A supple-
mental bar 25 is pivoted adjacent its for-
ward end as shown at 26 to the guide bar 105
24 and has a vertical slot 27 formed near its
rear end for adjustment of the supplemental
bar below or in alinement with the said
guide bar by means of a clamping member -
28 carried by the guide bar and engaged 110
through the slot so as to further regulate
the tipping of the point.1,079,355.
