IMPROVE- MENTS IN PLOUGHS
Year: 1885

page_text: JAMES HORNSBY Agricultural Engineer JEREMIAH MONEY Machine fitter and
WILLIAM GRICE Ploughman all of Spittlegate Iron Works Grantham in the
County of Lincoln do hereby declare the nature of our invention for IMPROVE-
MENTS IN PLOUGHS to be as follows:-
Our invention relates principally to double or multiple ploughs, and consists of
making the back body or bodies adjustable so that they may be placed nearer to or
further from the front body without altering the width of the furrow.
In practice this is found to be of great advantage when ploughing hard ground
the back body or bodies may be set as close to the front body as may be found
desirable, thus placing them in the most rigid position for work and making the
plough more easy to manage by the attendant.
Or when ploughing in straw manure or tangled weeds or working on rough
ground it may be found advantageous to move the hind body or bodies backwards
so as to give more room between them so that they shall not become clogged by
the large clods of earth or the straw manure or weeds lying on the surface.
The
We will now describe the manner in which our invention is carried out.
beams of the plough may be of any suitable material and shape. We prefer to
use bars of channel iron, the bars being by preference straight and parallel with
each other.
On these bars we mount the different parts of the plough and we adjust the
breadth of furrow by screwed stays between the beans. It is usual for these stays
to pass through the body and the beam and thus act as a bolt for securing the body
to the beam in a fixed position. Our improvement consists in not connecting the
body to the beam by this stay, but to fasten the stay to the beam only and make
the body of such shape that all parts of it are clear of the stay.
This may be done by making a slot in that side of the body that comes against
the beam-this slot must be large enough to clear the nut that secures the stay to
the beam or the top part of the body above the nut on the stay may be dispensed
with and the front and back ends of the body only shall come against the side of
the beam, the two ends of the body being made of such a shape as to give the
necessary support and adjustment.

page_text: By preference we connect the body to the beam by two staples, the ends of the
staples being screwed and a nut upon each end, one side of each staple passing
under, and the other side over the beam and through the body, the nuts screwing
the body fast up to the beam.
The hole in the body through which the staple passes may be slotted so as to
allow the point of the shares to be adjusted by a set screw through the body above
the beam.
When the plough is used as a single plough the body may be set forward thus
giving more equal balance making the plough more easy to manage and more easy
in draft.

page_text: We, JAMES HORNSBY, JEREMIAH MONEY, and WILLIAM GRICE, all of Grantham,
in the County of Lincoln do hereby declare, the nature of our invention for
IMPROVEMENTS IN PLOUGHS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
:-
The object of our invention is to improve and increase the efficiency of multiple
or single furrow ploughs, and consists of making the back body or bodies
adjustable, so that they may be placed nearer to the front body, or further away
from it without altering the width of the furrow. When ploughing hard ground
it is found to be of great advantage to set the back body as close to the front
body as may be found desirable, thus placing them in the most rigid position for
work and making the plough more easy to manage by the attendant.
Or, when ploughing in straw manure, or tangled weeds, or working on rough
ground, the hind body or bodies may be moved backwards so as to give more room
between the ploughs, so that they shall not become clogged by the large clods of
earth or other substances.
Our invention is illustrated by the accompanying drawings.
Fig. 1 is a plan view of a double furrow plough.
Fig. 2 is a side elevation of a double furrow plough.
Fig. 3 is a side view of the upper part of a plough body.
Similar letters of reference indicate corresponding parts throughout the drawings.
We will now describe the manner in which our invention is carried out.
The beams A. A. may be of any approved material and shape by preference we
prefer to use straight bars lying parallel with each other. B is the land wheel,
Cis the furrow wheel, D D are the breasts or turnfurrows, E E are the stays by
which the width of furrow is adjusted, they also form a rigid connection between
the two beams, F. F. are the bodies which it has been usual to make fast to the
beam by one of the stays E, passing through a hole in the body and the beam, thus
securing it in a fixed position. We now make the bodies adjustable by a slot G
shewn in Fig. 2 or the upper part of the slot may be dispensed with, and the body
shaped as shewn at Fig. 3., thus allowing adjustment so that the ploughs may be
set in the most desirable position for the different kinds of work they have to
perform. By preference we fasten those bodies requiring adjustment to the beams
by two staples, each end of the staple being screwed and fitted with a nut, one
end of the staple passing under, the other over the beam and through the body, the
nuts screwing the body fast to the beam. The holes in the body through which
the front staple passes is slotted so as to allow the point of the share to be adjusted
by the set-screw J, through the body above the beam.
It will be understood that our improvement is equally useful for single furrow,
as well as multiple furrow ploughs, as it allows the plough to be adjusted to suit

draught.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
The improved construction and combination of parts, substantially as described
and illustrated in the accompanying drawings.
