Improvements in Plows.
I, EDGAR FLY GIROD, of Rayville, in the County of Richland, and State of
Louisiana, United States of America, Blacksmith, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement:-
My invention relates to improvements in plows; and the object that I have in
view is to improve the means for joining the share detachably to the moldboard
and landside without the employment of bolts, screws, or rivets and to effect
the wedging of the share firmly in place by the resistance of the soil to the
implement.
A further object is to arrange the several elements in a way to secure a flush
joint between the landside, the moldboard, and the share, and also to provide
for locking the parts firmly together against tendency to accidental displace-
ment in any direction.
With these ends in view the invention consists in the novel construction and
arrangement of parts, which will be hereinafter fully described and claimed.
To enable others to understand the invention, I have illustrated it in the
accompanying drawings, forming a part of this specification, and in which-
Figure 1 is an inverted or bottom plan view of a plow having a share con-
structed in accordance with my invention.
Figure 2 is an elevation looking at the landside of the plow.
Figure 3 is a longitudinal sectional elevation on the plane indicated by the
dotted line 3-3 of Figure 1.
Figure 4 is a detail horizontal section through the landside and the sole-flange
of the share, the plane of section being indicated by the dotted line 4 of Figure 2.
Figure 5 is a perspective view of the share detached from the moldboard and
landside.
Figure 6 is a detail perspective view of a part of the landside and standard
to show the crotch or seat for the reception of the sole-flange on the share.
Like numerals of reference denote like and corresponding parts in each of
the several figures of the drawings.
The standard or stock 10 of a plow embodying my invention has its lower
forward extremity reduced in width to produce the point 11, and this stock
and the moldboard 12 are united in any way approved by those skilled in the
art. The landside 13 is arranged to overlap the lower part of the stock, and
this landside is peculiarly constructed, as will presently appear, and is united
to the pointed end 11 of the stock to form therewith a crotch or seat, as shown
by Figure 6. The handles 14 of the implement are tied together and united to
the beam in a manner well understood by those skilled in the art, and the lower
end of one handle is attached, as at 15, to the heel of the landside, while the
corresponding end of the other handle is united to a lug 16 on the rear neutral
face of the moldboard.

page_text: The front extremity of the landside 13 is formed with a downward and rear-
ward sloping edge 17, and this sloping edge is beveled inwardly toward the
pointed extremity 11 of the stock.
The share 20 is cast in a single piece, with a sole-flange 23, that protrudes
beyond the rear edge of the share, which is designed to underlap the lower edge
of the moldboard and produce a flush joint between the share and the moldboard.
As is usual in the art, the share has a point 21 and the front cutting edge 22;
but in lieu of making the point integral with the share, as herein shown, I
may employ a separable or detachable point, which, however, I do not deem it
necessary to illustrate. The sole-flange 23 of the share, which projects beyond
the rear edge thereof, is arranged to overlap the pointed end 11 of the stock,
and the projecting end of the sole-flange is peculiarly fashioned to fit snugly to
the end of the landside, so that the sole-flange and the landside may interlock,
and the faces and edges thereof will lie flush to avoid any protruding parts at
the joint between the landside and the share. To attain this end, form the
projecting rear extremity of the sole-flange 23 with a sloping edge 24, that
inclines downwardly and rearwardly at an angle corresponding to the edge 17
of the landside, and this sloping edge 24 of the sole-flange is beveled inwardly
to correspond with the bevel 18 of the landside. It will thus be observed that
the share has its sole-flange .constructed to overlap the pointed end of the stock
and to underlap the sloping and beveled edge of the landside when the share is
properly fitted to the moldboard and stock, and the face, as well as the edge, of
the sole-flange lies flush to the corresponding parts of the landside.
On the under neutral face of the share are cast the spaced lugs 25, having the
beveled edges.25, and these lugs are spaced to forin between their beveled
edges a tapered key-seat 20. To lock the share to the moldboard, I resort to
the employment of a tapering key or wedge 27, which is arranged to fit snugly
against the curved rear face of the moldboard and is provided with a longitudinal
slot 29, through which passes the bolts 30, that are rigid with the moldboard.
The key or wedge is held on the under side of the moldboard by the nuts 31,
which are screwed on the bolt to bear against the key, and the tapered working
end of this key or wedge protrudes beyond the lower edge of the moldboard,
so as to fit into the key-seat formed by and between the beveled edges of the
lugs on the share. The heel of this key or wedge has an offstanding flange 28,
which provides a convenient means by which the key may be adjusted.
To remove the share from the plow, the key or wedge is driven out of the key-
seat in the share, and the latter is then withdrawn from the moldboard, so as
to disengage its sole-flange from the crotch or seat at the juncture of the landside
and stock. To replace the pointed share, it is adjusted for its rear edge to
underlap the moldboard and to have the sloping and beveled heel of its sole-
flange enter the crotch or seat of the landside and stock, so that the heel of
said sole-flange will overlap the pointed end of the stock and will underlap the
sloping and beveled front extremity of the landside, after which the wedge or
key is driven into the key-seat formed by the lugs on the share. The share is
thus attached to the plow without the employment of bolts or their equivalents
to hold it in place; but, on the contrary, the share of my invention is interlocked
with certain parts of the plow and secured in place by a key or wedge in a
manner to have the share forced firmly into position by the resistance of the soil
when the implement is in service. The parts are simple in construction, to
the end that the share may be cast in a single piece and the parts readily
assembled together without finishing the same by hand. The share may be
easily detached and quickly applied by the farmer, and the absence of bolts to
fasten the share expedites the labor of attaching or detaching it.
Changes may be made in the form of some of the parts while their essential
features are retained and the spirit of the invention embodied. Hence I do not
desire to be limited to the precise form of all the paits as shown, reserving the
right to vary therefrom.

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. In a plow, the combination of a share provided on its rear face with the
spaced lugs having their opposing edges beveled and forming a dovetailed way,
a moldboard, a slotted endwise-movable key curved to conform to the mold-
board and fitted thereto in alinement with the dovetailed way for adjustment
into engagement with the lugs, and bolts fixed to the moldboard and fitting in
the slots of the key to slidably hold the latter in place, substantially as described.
2. The combination, in a plow, with a moldboard and a stock, of the landside
provided with a sloping and beveled front extremity which laps the stock and
forms therewith a seat or crotch, a share having its sole-flange provided with the
sloping and beveled heel which is fitted snugly to the sloping and beveled edge,
of the landside, for the sole-flange to lie flush with the face of said landside,
and means for fastening the share to the moldboard, substantially as described.
3. In a plow, the combination with a moldboard, and a stock having a pointed
extremity, of the landside having the inclined and beveled extremity which is
arranged to overlap the stock, a share having its sole-flange formed with a sloping
and beveled heel and fitted to the end of the landside for the faces of the sole-
flange and the landside to lie flush with each other, the beveled lugs on the rear
face of the share, and a key or wedge slidably confined on the moldboard and
engaging with said lugs, for the purposes described, substantially as set forth.
