IMPROVEMENTS IN "PLOWS
Year: 1885

page_text: I GEORGE BURDET CASADAY, of Hudson Township, in the County of La Porte,
and State of Indiana, in the United States of America, gentleman, do hereby
declare the nature of my invention for IMPROVEMENTS IN "PLOWS" and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
Fig. 1, is a perspective of a plow embodying my invention.
Fig 2 is a side elevation.
Fig. 3, a front elevation with the reversible parts removed.
Fig. 4, a perspective of the removable wing.
Fig. 5, a perspective of the reversible combined cutter and point, and
Fig. 6, a detail showing the underside of the wing bearing.
My invention relates to certain improvements in plows having reversible cutting
edges and has for its object to produce a combined reversible shin or cutter and
point, and a reversible wing to be used in combination with the said combined
cutter and point.
In the drawings:-
:-
o
A, represents the standard, B, the landside and, C, the mold board.
The lower edge of the mold board forms a shoulder against which the wing or
shoe bears as hereinafter described, D, is a reversible combined cutter and point
having two opposite wearing faces, d, d, and two opposite cutting edges, d', 'd¹.
Said wearing faces being continued and converging to a common point, d².
a, is a groove on the upper side of the standard between the mold board and
landside, one side of said groove being perpendicular and conforming to the shape
of the sides, d, d³, of the cutter, the other side of the groove conforming to the
shape of the wearing faces of the cutter.
The upper end of the combined cutter and point is provided with a V, shaped
notch, E, having projecting angular edges, e, said notch engages with a corre-
spondingly shaped shoulder, A', on the standard having angular grooves, a¹, in its
edges. This shoulder forms the main bearing for the combined cutter and point.
When adjusted the inner side of the cutter rests against the landside edge of the
mold board and its bearing face in use conforms to the curves of said mold board
and forms a continuation of the same.

page_text: The outer side of said cutter is in a plano with and forms a continuation of the
landside.
The upper edge of the landside conforms to the curve of the wearing faces of the
cutter. The wearing face not in use rests in the groove, a, on the standard.
The point, d², extends down over the landside end of the wing bearing and forms
the plow point.
ds, d, are corresponding triangular recesses cut in the lower portion of the
opposite faces of the combined cutter and point.
The recess in the face not in use fits over a correspondingly shaped raised
shoulder, a, on the lower end of the standard; the outer edges of the recess rest
against the shoulder, b, and end of the landside forming a close joint with the same
and thus prevents the lateral displacement of said cutter and point when the wing
hereinafter described bears against the same.
F, is a wedge shaped bearing on the lower part of the standard extending
from the point to the rear end of the mold board, f, f, are shoulders on the under-
side of the bearing, F.
The lower line of the mold board forms a shoulder on the upper side of the
bearing, F, the same distance from its edge as the shoulders, ff.
f¹, is a notch near the center of the bearing, f2 is a bolt-hole and ƒ³ a notch near
the forward end of the bearing. G, is a hollow reversible wing having two
opposite wearing faces its ends being open; said wing fits on the bearing, F, and is
held in place by a hook bolt, g, hooked on a pin, gl, and passing up through the
opening, f, is held in place by a suitable nut.
The upper edge of the wing fits snugly against the lower edge of the mold-board.
When adjusted the upper forward, corner of the wing projects over the face of the
cutter and fits in the triangular recess on the wearing face of the cutter which is in
use, and securely locks the same in position.
•
The upper end of the combined reversible cutter and point is secured by the
V, shaped notch engaging with the shoulder, A¹, on the standard.
In the construction I have described, I produce a simple, strong and durable
plow having reversible cutting edges and a combined reversible cutter and plow-
point. The bearing surfaces of said reversible parts being independent of their
wearing faces. My plow has a further advantage in that it requires but few bolts
to secure the various parts in place and said bolts being so arranged that they are
all out of the way and do not drag in the bottom of the furrow.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1, In a plow a reversible combined cutter and point having two cutting edges
and two corresponding converging faces continued to a common point substantially
as shown and described.
2, In a plow, the combination with the standard, and mold-board of a reversible
combined cutter and point secured to the standard and having two cutting edges
and opposite corresponding and converging faces continued to a common point and
presenting when either face is in use a point, a cutting edge and a wearing face
conforming to and forming a continuation of the mold-board substantially as shown
and described.
3, In a plow the combination with the standard, mold-board and landside of a
reversible combined cutter and point secured to the standard and presenting when
either face is in use, a point a cutting edge and a surface conforming to and forming
a continuation of the landside substantially as shown and described.
4, In a plow, a standard, a mold-board and a reversible combined cutter and
point secured to the standard, in combination with a removable wing operating
when in position to over-lap the combined cutter and point and positively lock the
same in place substantially as shown and described.

page_text: 5, In a plow, a mold board, a standard, having a V, shaped shoulder, A¹, a
reversible combined cutter and point having a V, shaped notch, E, interlocking
with the shoulder on the standard, in combination with a reversible wing, said
wing operating when in place to overlap the cutter and point and positively lock
the same in place substantially as shown and described.
6, In a plow, a mold board, a standard provided with a V, shaped shoulder, A¹,
and a raised triangular shoulder, a², on its lower end, in combination with a
reversible combined cutter and point provided with the V, shaped notch, E, and
triangular recesses, d', d', and a reversible wing operating when in position to
engage with one of the recesses, d, and lock the combined cutter and point in place,
substantially as shown and described.
7, In a plow, a mold board, a standard, having a V, shaped shoulder A¹, a
reversible combined cutter and point having a V, shaped "notch, E interlocking
with the shoulder on the standard, in combination with a hollow reversible wing
secured on a suitable bearing on the standard, and operating when in position, to
interlock with the combined cutter and point and hold the same in place, sub-
stantially as shown and described.
