Gower, Duke of Sutherland, of Stafford House, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN IMPLEMENTS TO BE
DO COM POWER
"
PROVISIONAL SPECIFICATION left by the said George Grenville
William Sutherland Leveson Gower, Duke of Sutherland, at the
Office of the Commissioners of Patents, with his Petition, on the
24th January 1874.
I, GEORGE GRANVILLE WILLIAM SUTHERLAND LEVESON GOWER, DUKE
OF SUTHERLAND, of Stafford House, in the County of Middlesex, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
IMPLEMENTS TO BE USED IN CULTIVATING WASTE OR MOOR LAND BY STEAM POWER,"
to be as follows:-
This Invention has for its object the improvement of implements used
for cultivating waste or moor land. For this purpose I employ a turn

page_text: wrest or two-headed plough carried on large rollers fitted with revolving
coulters as described in the Specification of a Patent granted to John
McLennan, on the 24th October 1872 (No. 3151). The revolving coulters
serve for cutting through the ling or gorse commonly found on unculti-
vated land, and also for lifting the plough should it meet with obstacles.
In addition to these purposes I now employ the revolving coulters for
steering the plough in the required direction. The coulters I mount on
eccentric axles carried on the axles of the rollers in order to facilitate the
adjustment of their depth of cut, and I also combine with such ploughs
subsoil tines for the purpose of removing large stones and cultivating the
land to a greater depth than it is desirable to turn over by the plough.
To effect this I attach one or more tines fore and aft of the plough in
such manner that they are not rigidly fixed to the frame, and I connect
them to the hauling ropes so that the pull of the rope which is for the
time acting as the hauling rope keeps the time or tines at the rear end
of the implement into the land, the weight and tautness of the slack
or out-paying rope is also arranged to assist in keeping the tine or tines
to their work. When the implement arrives at the headland the slack
rope becomes the hauling rope, and the tine or tines which have worked
the bout are lifted by the rope out of the land, and at the same time the
opposite set are brought into work. A tine or tines thus mounted at
cach end of the frame and supported on rollers carrying steering coulters
as above described may also be used as a separate implement without
having a plough combined with it.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said George Granville William Sutherland Leveson
Gower, Duke of Sutherland, in the Great Seal Patent Office on the
24th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
GRANVILLE WILLIAM SUTHERLAND LEVESON GOWER, DUKE OF SUTHER- 3
LAND, of Stafford House, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of January, in the
year of our Lord One thousand eight hundred and seventy-four, in the

page_text: thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George Granville William
Sutherland Leveson Gower, Duke of Sutherland, Her special license
that I, the said George Granville William Sutherland Leveson Gower,
Duke of Sutherland, my executors, administrators, and assigns, or such
others as I, the said George Granville William Sutherland Leveson
Gower, Duke of Sutherland, 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 IMPLEMENTS TO BE USED IN
CULTIVATING WASTE OR MOOR LAND BY STEAM POWER," upon the condition.
(amongst others) that I, the said George Granville William Sutherland
Leveson Gower, Duke of Sutherland, my executors or administrators,
by an instrument 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 cause the same to be filed in the Great Scal Patent Office, within
six calender months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said George Granville William Suther-
land Leveson Gower, Duke of Sutherland, do hereby declare the nature
of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
This Invention has for its object the improvement of implements used
for cultivating waste or moor land. For this purpose I employ a turn
wrest or two-headed plough carried on large rollers fitted with revolving
coulters, as described in the Specification of a Patent granted to John
McLennan on the 24th October 1872 (No. 3151). The revolving coulters
serve for cutting through the ling or gorse commonly found on unculti-
vated land and also for lifting the plough should it meet with obstacles.
In addition to these purposes I now employ the revolving coulters for
steering the plough in the required direction. .
2. I also mount the coulters on eccentric axles carried on the axles of
the rollers in order to facilitate the adjustment of their depth of cut.

page_text: 3. I also combine with such ploughs subsoil tines for the purpose of
removing large stones and cultivating the land to a greater depth than
it is desirable to turn over by the plough. To effect this I attach one or
more tines fore and aft of the plough in such manner that they are not
rigidly fixed to the frame, and I connect them to the hauling ropes, so 5
that the pull of the rope which is for the time acting as the hauling
rope, keeps the tine or tines at the rear end of the implement into the
land, the weight and tautness of the slack or out-paying rope is also
arranged to assist in keeping the tine or tines to their work. When the
implement arrives at the headland the slack rope becomes the hauling 1
rope, and the tine or tines which have worked the bout are lifted by
the rope out of the land, and at the same time the opposite set are
brought into work.
4. A tine or tines thus mounted at each end of a frame and supported
on rollers carrying steering coulters, as above described, may also be 1
used as a separate implement without having a plough combined with it.
Having thus described the nature of my several improvements I will
proceed to describe more fully the manner of performing the same.
Figure 1 of the Drawings hereunto annexed shows a side view, and
Figure 2 a plan view of an implement having all my improvements
applied to it.
a, a, is the frame of the implement which carries the turn wrest
or double-headed plough b, b; c, c, c, c, are the rollers; d, d, are the
revolving coulters which I now cause to be steered by the levers e, e,
and segments f.f. These segments and levers are actuated by the turning
of the hand wheels g, g, which work the worm gearing into the worm
wheel k. The shaft upon which the worm wheel is keyed has also keyed
on to it at its bottom end a pinion which gears into a pinion of the same
size mounted loose on a stud. This loose pinion gears into the segment
on the steering arms or levers e, e. When the implement has arrived at
the end of the field and is required to go back again the loose pinion is
shifted from the segment on the steering lever with which it has been
working to the segment on the steering lever at the opposite end of the
plough. L, L, are rollers mounted on the side of the frame and serve
to roll down the earth, &c., thrown out by the turn wrest or double-
headed plough; m, m, are eccentric bosses upon which the revolving
coulters d, d, are mounted; by turning the eccentrics round the depth of

page_text: cut of the revolving coulters can be regulated at pleasure; n, n, are the
subsoil tines mounted one at each end of the frame on a pin or centre
upon which they are free to work loosely. These two tines are con-
nected together by the coupling bar o, and the hauling ropes are coupled
to the tines, as shewn by the Drawings. By this means the rope which for
the time is acting as the pulling rope pulls the fore tine out of the
|furrow and depresses the aft or hind tine into the furrow. Levers are
also fixed loosely into sockets P, P, at the outer end of which levers the
tail rope is caused to be carried, thereby adding the tautness of the tail
rope to assist in keeping the hind tine into its work.
As before stated a tine or tines mounted in the manner above described
at each end of a frame which is supported on rollers carrying steering
coulters may be used as a separate implement without having a plough
combined with it.
I claim the several improvements herein described in implements. to
be used in cultivating waste or moor land by steam power.
In witness whereof, I, the said George Granville William Suther-
land Leveson Gower, Duke of Sutherland, have hereunto set
my hand and seal, this Twenty-first day of July, in the year
of our Lord One thousand eight hundred and seventy-four.
