UNITED STATES PATENT OFFICE.
JAMES S. FERRIS, OF WAXAHACHIE, TEXAS.
MOLDBOARD.1,083,606.
Specification of Letters Patent.
Patented Jan.6, 1914.
Application filed April 3, 1913. Serial No. 758,533.
To all whom it may concern: .
Be it known that I, JAMES S. FERRIS, a
citizen of the United States, residing at
Waxahachie, in the county of Ellis and State
5 of Texas, have invented certain new and
useful Improvements in Moldboards, of
which the following is a specification.
My invention relates to mold boards for
plows, and relates more particularly to that
10 type of mold board which has its working
face coated with plaster of Paris to more
efficiently shed sticky or moist soil, such as
that commonly termed "black waxy land."
In the present practice, the plaster of
15 Paris coating is held upon the working face
of the mold board by bolting or riveting
certain pieces upon said face to provide a
retention to said coating, and in order that
the holes for the rivets or bolts may be bored,
20 the temper must be drawn out of the mold
board and again restored after the holes
have been bored. This process is rather ex-
pensive and moreover is apt to leave the
mold board in an impaired condition. This
25 method of retaining the plaster of Paris
coating upon the mold board face is further
objectionable for the reason that a very con-
siderable amount of work is necessary to re-
move the said pieces when it is desired to
30 use the plow without the plaster of Paris
coating.
It is the object of my invention to provide
a device for retaining a plaster of Paris coat-
ing upon a mold board, which device may be
35 easily attached to or detached from the mold
board, without necessitating boring any
holes in the mold board or otherwise altering
the same.
A further object of my invention is to
40 provide a device that will be strong, durable,
simple and efficient and comparatively easy
to construct and one which will not be likely
to get out of order.
With these objects in view, my invention
45 has relation to certain novel features of the
construction and use, an example of which is
described in the following specification, and
illustrated in the accompanying drawing,
wherein:
5o Figure 1 is a top view of a mold board
provided with a plaster of Paris coating re-
tained by the novel device constituting my
invention. Fig. 2 is a transverse sectional
view taken upon the line x-x of Fig. 1.
55 Referring now more particularly to the
drawing, wherein like reference charactersdesignate similar parts in both of the fig-
ures, the numeral 1 denotes an ordinary
plow mold board having its working face
coated with plaster of Paris as indicated at 60
2. The'short edge of the mold board which
will come adjacent to the plow point is
designated by the numeral 1a.
Upon the two opposite elongated edges of
the mold board are mounted rods 3 and 4 65
of circular cross section, which rods con-
form to the curve of said mold board edges
and serve to retain the plaster of Paris coat-
ing against a displacement parallel with the
mold board face. Since the cylindrical sur- 70
faces of said rods 3 and 4 permit a certain
amount of the plaster of Paris to enter be-
tween said rods and the mold board face,
they will also to some extent retain the coat-
ing against displacement outward from the 76
mold board face. To each of said rods there
is pivotally secured a number of hooks 5, the
hooks 5 of one rod being extended toward
those of the other and engaged with same
as indicated at 5a. The lengths of the hooks 80
will preferably be such that engagement be-
tween the two sets will be made above the
center portion of the mold board. The riv-
ets which establish a pivotal connection be-
tween the hooks 5 and the correlated rods 3 $6
and 4 are designated by the numeral 6. The
outer end of each hook 5 is formed with a
hook 7 which is adapted to engage the corre-
lated mold board edge as is clearly shown in
Fig. 2. The members 5 serve the double go
purpose of reinforcing and retaining the
plaster of Paris coating and also retaining
the members 3 and 4 in their proper posi-
tions relative to the mold board. The mem-
bers 5 will preferably be spaced slightly 45
above the mold board face in order to better
retain the plaster of Paris coating against
displacement from said face.
The above described device is such that it
may be very quickly applied to a mold 100
board before the plaster of Paris is poured
upon the same, and when it is desired to use
the mold board in the ordinary manner, the
plaster of Paris may be broken off and the
retaining device easily removed. 105
The invention is presented as including all
such modifications and changes as properly
come within the scope of the following
claims.
What I claim is: lie

perforate plate, having a continuous face
