page_text: LETTERS PATENT to David Greig, of the Steam Plough Works, Leeds,
in the County of York, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR CULTIVATING OR TILLING LAND.”
APPARATUS FOR CULTIVATING OR TILLING LAND."
Sealed the 21st September 1875, and dated the 28th April 1875.
PROVISIONAL SPECIFICATION left by the said David Greig at the
Office of the Commissioners of Patents, with his Petition, on
the 28th April 1875.
I, DAVID GREIG, of the Steam Plough Works, Leeds, in the County of
York, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR CULTIVATING OR TILLING LAND," to be as follows:-
This Invention has for its object improvements in apparatus for
cultivating or tilling land.
In the construction of the implements used for steam cultivation,
commonly known as balance ploughs, it is customary to employ a beam
or frame mounted on a pair of wheels in the middle, and having a set of
tilling tools at each end. When more than a certain number of such

page_text: tilling tools are used it is found that the implement becomes incon-
venient and unmanageable on account of its great length and width.
My improvements consist in extending the framing to which the
tilling tools are, attached so as to bring it outside the carrying wheel,
and attaching to it additional tilling tools. This extension of the
framing is made by the addition of a frame which is connected with
the main frame by joints; it is carried by an outside wheel, and will
thus freely adapt itself to any inequalities of the ground. The jointed
portion of the framing can be lifted clear at the headland, and it can
also be turned back over the carrying wheels on to the main frame
when the implement is not working, so as to reduce the breadth of the
implement.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said David Greig in the Great Seal Patent Office on
the 28th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
GREIG, of the Steam Plough. Works, Leeds, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twenty-eighth day of April, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the, said David Greig, Her special license
that I, the said David Greig, my executors, administrators, and assigns,
or such others as I, the said David Greig, my executors, administrators,
and assigns, should at any time agree with, and no. others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
CULTIVATING OR TILLING LAND," upon the condition (amongst others) that,
I, the said David Greig, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and

page_text: cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said David Greig, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
-
This Invention has for its object improvements in apparatus for
cultivating or tilling land.
In the construction of the implements used for steam cultivation,
commonly known as balance ploughs, it is customary to employ a beam
or frame mounted on a pair of wheels in the middle, and having a set of
tilling tools at each end. When more than a certain number of such
tilling tools are used it is found that the implement becomes inconvenient
and unmanageable on account of its great length and width.
My improvements consist in extending the framing to which the
tilling tools are attached so as to bring it outside the carrying wheel,
and attaching to it additional tilling tools. This extension of the
framing is made by the addition of a frame which is connected with
the main frame by joints; it is carried by an outside wheel, and will
thus freely adapt itself to any inequalities of the ground. The jointed
portion of the framing can be lifted clear at the headland, and it can
also be turned back over the carrying wheels on to the main frame
when the implement is not working, so as to reduce the breadth of the
implement.
In the Drawing hereunto annexed I have shewn a double balance
plough constructed as above described.
Figure 1 is a side elevation, and Figure 2 a plan view of the plough.
In these Figures A, A, is the beam or frame, which carries a set of
tilling tools at each end; B, B, are the carrying wheels which support
the beam at its centre; C is the extension of the framing jointed to the
main framing at D, D; E is a wheel for supporting the outer end of
this jointed frame; the wheel can be raised or lowered, as shewn, by a
screw and hand wheel. The frame C is formed, as shown, so as to be
clear of the carrying wheel B, and so that it can be turned back on the
hinges D, and lie above the main frame when the implement is not at

page_text: work, the steering spindles being then removed from their sockets.
Each end of the frame C is in the implement shewn in the Drawing
made to carry three ploughs F, F, F, but the number of ploughs or
implements carried by this frame may be varied.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I claim, the con-
struction of balance ploughs and cultivating implements with an
extension of the beam or frame outside of the carrying wheel, and
hinged to the main beam or frame, substantially as herein-before
described.
In witness whereof, I, the said David Greig, have hereunto sct my
hand and scal, this Twenty-sixth day of October, in the year of
our Lord One thousand eight hundred and seventy-five.
