PROVISIONAL SPECIFICATION.
Improvement in Plows.
I, JOHN PITT BAYLY, of 18 Fulham Place Paddington, in the County of
London, Patent Agent, (a communication to me from abroad by John Shearer of
South Bend Indiana, U.S.A., Inventor,) do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to provide plows with a shield in front of the
blade or blades thereof to protect them from forcible contact with stones and other
hard substances.
By this invention, a standard is pivoted to the shaft of the plow just in front of
the plow blade or blades. The lower end of this standard carries the shield, which
consists of a metal plate which is adjustably attached to the side of the standard,
and which has the front portion of its upper edge curved inwardly over the plow
blades, and the rear part of its under edge slightly cut away. This shield can be
regulated in height by means of apertures which are arranged at intervals along
the standard and through which a pin may be passed into the plow shaft. The
upper end of the standard has a rod attached to it, the opposite thereof being
attached to a spiral spring secured to a cross-bar or other convenient part of the
plow-frame. By means of this spiral spring the shield is enabled to give to the
force occasioned by its contact with any hard substance.

Improvement in Plows.
1, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by John Shearer, of South Bend, Indiana, U.S.A.
Inventor,) and in what manner the same is to be performed, to be particularly
described and ascertained in & by the following statement :—
This invention relates to a certain new and useful improvement in plows.
Reference being had to the accompanying drawings, which form a part of this
Specification.
Figure 1 is a perspective view of my device attached to one pattern of my
shovel-plows. Fig. 2 is a side elevation of the same; and Fig. 3 represents
a modification of the device adapted to be attached to the other side of a plow, a
portion being broken away.
Nothing is more common in the ploughing and cultivation of corn, potatoes, and
other similar crops than for the dirt to be thrown on top of the vines, burying a
portion of them, and necessitating the stoppage of the cultivator that the farmer
may remove the vines by hand. Otherwise the plants are injured by a portion of
their tops being allowed to remain under the ground or by being broken off.
My invention relates to attachments for plows or cultivators, and has for its
object to provide efficient means for preventing the earth from being thrown upon
the tops or vines of the plants, as above referred to. I accomplish this object by
the device illustrated in the accompanying drawings, in which like letters of
reference denote corresponding parts in all the figures.

page_text: It is not my intention to confine the use of my attachment or shield to the
particular pattern of plow in connection with which it is shown in the drawings.
It can be used with equal advantage with nearly every pattern of cultivator-plow
or shovel-plow, and it may be attached to one side of the plow, as shown in the
drawings, or two shields may be attached to the same plow or cultivator, one upon
each side.
The shield shown in Figs. 1 and 2 is intended to be used on the right side of the
plow but it will be seen that a like construction may be employed in a shield for
the left side, as shown in Fig. 3.
Referring to the drawings, the letter A designates the beam of a cultivator or
shovel-plow, on which is hinged the standard B by means of the pivots B¹. Below
the point of adjustment to the beam the standard is curved outwardly and then
forwardly, forming a sort of foot b. To this foot is bolted th shield C. The con-
struction or shape of this shield is best illustrated by reference to the drawings.
It will be seen that the top is curved or rounded inwardly, as shown at c, and that
the bottom is cut away, as shown at d. The shield is provided with a series of
perforations or bolt-holes e, in any one of which the bolt f may be placed. The
standard B also has several holes, through any one of which it may be attached
to the beam A. The upper end of the standard is connected by means of a rod D
and coiled spring E to the round connecting the handles.
The operation of my invention is as follows:-
It will be seen that the point of the shield runs considerably in advance of the
shovel or plow proper and that it rests at a little distance to the side of the plow,
also that the point d, at which the shield is cut away, rests nearly opposite the plow
or shovel.
As the plow moves along the vines are caught and raised by the curved
portion passing under them. At the same time the dirt is thrown from the shovel
against the plant at the point d, where said shield is cut away. The top of the
shield is curved and made smooth, in order that it may not cut or injure the vines,
and for the same reason the front side of the standard at the point h, near where
it is fastened by the bolt is rounded and curved, in order that it may not catch
or cut the vines. If it is desired that the point of the shield may be relatively
more depressed or raised, it is adjusted by placing the bolt in a different one of
the series of bolt-holes c. The entire shield may be raised or lowered by means
of the holes of the standard by which said standard is fastened to the beam of
the cultivator or plow. The spring E is provided in order to give a certain amount
of play to the shield in case it strikes small stones or other slight obstructions.
By this means when the point of the shield strikes a small stone it will drop,
pass under, raise the stone, and return to its normal position by the tension of
the spring.
The standard B without departing from the spirit of the invention may be bent
or formed in various ways in order that the shield may be attached to plows or
cultivators of different patterns.
It will be seen that the shields shown in Figs. 2 and 3 are made to face in
opposite directions, but are symmetrical in form and construction and are adapted
to be applied to the right and left sides, respectively, of the cultivator or plow.
In some cases it may be found desirable to bolt the standard B firmly to the
beam of the plow and dispense with the upward extension, the rod D, and coiled
spring E.
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. The combination, with the beam A and pivoted standard B, provided with a
series of holes g, of the shield C, provided with a series of holes e, by which it is
adjustably secured to the upright B, said shield consisting of a metal plate curved
inwardly at small c and having its bottom cut away at 4, substantially as
described.

page_text: 2. In a plow, the combination of the beam A, the standard B, pivoted thereto,
the shield C, having bolt-holes e and curved inwardly at c and cut away at d, the
bar D, secured to the standard B, and the coiled spring E, connected to the bar D
and to the plow-handles, substantially as described.
