Year: 1873

page_text: LETTERS PATENT to David Greig and Robert Burton; both of the
Steam Plough Works, Leeds, in the County of York, Engineers, for.
the Invention of "IMPROVEMENTS IN APPARATUS FOR ACTUATING STEAM
Sealed the 15th May 1874, and dated the 1st December 1873.
PROVISIONAL SPECIFICATION left by the said David Greig and Robert
Burton at the Office of the Commissioners of Patents, with their
Petition, on the 1st December 1873.
We, DAVID GREIG and ROBERT BURTON, both of the Steam Plough
Works, Leeds, in the County of York, Engineers, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR..
ACTUATING STEAM PLOUGHS, AND OTHER AGRICULTURAL IMPLEMENTS," to be as
follows:-
-
The principle object of this Invention" is to provide an efficient
winding apparatus for ploughing and cultivating land with a triangular
arrangement of tackle. When working on this system the winding
apparatus and engine are stationary at the apex of the triangle, and the

page_text: implement is hauled to and fro along the base line by the hauling ropes
which pass from the winding apparatus to the implement around two
anchored pulleys, one at each extremity of the base or line of work. As
the work progresses the anchored pulleys are made to traverse towards
the winding apparatus so as to bring the implement on to fresh ground
at each bout.
To carry out this system it is requisite that the winding apparatus
should admit of the ropes being led to and from it at any angles without
interfering with the automatic coiling of the ropes upon the drums.
The winding apparatus which we have designed for this purpose is
provided with two winding drums on vertical axes and capable of being
driven alternately by spur gear which itself is driven by a belt or union
joint from the steam engine.
The frame of the winding apparatus, which is mounted on small
wheels for travelling, is so arranged that the ropes may be led from the
drums without impediment either parallel the one to the other or inclined
at any angle up to 180 degrees or nearly so, and each drum has an
automatic coiling apparatus which can turn around the axis of its drum
and so follow the rope to any position.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said David Greig and Robert Burton in the Great Seal
Patent Office on the 1st June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, DAVID
GREIG and ROBERT BURTON, both of the Steam Plough Works, Leeds,
in the County of York, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of December, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-.
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said David Greig and Robert Burton, Her
special license that we, the said David Greig and Robert Burton, our
executors, administrators, and assigns, or such others as we, the said
David Greig and Robert Burton, our executors, administrators, and

page_text: assigns, should at any time agrec with, and no others, from time to
time and at all times thereafter during 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 ACTUATING
STEAM PLOUGHS, AND OTHER AGRICULTURAL IMPLEMENTS," upon the condition
(amongst others) that we, the said David Greig and Robert Burton, our
executors or administrators, by an instrument in writing under our, or
their hands and seals, or under the hand and seal of one of us or them,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and
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

page_text: such as is commonly used by farmers; 6 is the winding apparatus con-
nected with the engine by means of a universal jointed shaft; c, c, are
carriages carrying guide pulleys around which the hauling ropes pass.
The wheels of these carriages are provided with discs cutting into the
ground so that they may be able to resist the lateral strain of the
hauling ropes upon them. These carriages as the work progresses are
from time to time drawn forward towards fixed anchors with which they
are connected by ropes. d is a balance plough, or any other suitable
tilling implement may be used; e, e, are rope porters to keep the
hauling ropes off the ground to save wear and tear as far as it can be
done conveniently.
Figure 2 is a plan, and Figure 3 is a vertical section of the winding
apparatus to a larger scale. a, a, is a frame supported on two pairs of
wheels b, b, and the front pair has a locking motion for convenience in
travelling from place to place; a', a¹, is an upright frame fixed to the
frame a to carry the vertical shaft c and the horizontal shaft d which
are geared together by the bevelled wheels c¹ and d keyed upon them
respectively, and the shaft d is driven by the engine as is shewn in
Figure 1. The frame a also carries two turned uprights e, e, which at
their upper ends are also connected by the top plate with the frame a¹.
The winding drums 9, 9, are mounted upon the uprights e, e,
and are
able to turn freely upon them, one flange of each drum is separate and
attached to the barrel by T headed bolts. g¹, g¹, are rings of teeth.
formed on the fixed flanges of the drums, and they gear with pinions h, h,
upon the shaft c. These pinions are free on the shaft, but by a clutch i
sliding on the shaft with a groove and feather either the one or the
other can be made to revolve with the shaft and drive its drum so as to
cause it to wind up the hauling rope. k is a hand lever by which the..

page_text: clutch is worked. Around each drum there is a friction belt . It is
provided with a wooden, lining and. has notches in its edge into which
the pawl m.drops. The pawl allows the belt to revolve with the drum
whilst the hauling rope is being wound upon it, but whilst the rope is
being drawn off the drum the pawl stops the rotation of the ring and so
the drum is retarded to the extent necessary to keep the rope somewhat
taut and to prevent the drum from overrunning. The tightness of the
belt can be adjusted at pleasure. Each drum 9 carries a spindle n on
which a double pinion o is mounted so as to be able to turn freely ; the
double pinion o gears with two toothed wheels p and q; the lower
wheel p is mounted freely upon the upright e, and upon the elongated
boss of the wheel p the wheel q is carried, the boss of the wheel p also
supports the pivots about which a lever 7. is able to rock, and a small
friction pulley 1 carried by the lever enters a cam groove q¹ formed
upon the wheel q; s is a stem connected to the lever and it is provided
with two guide pulleys between which the hauling rope passes to and
from the drum; thus as the drum revolves the wheel q is caused to turn
slowly upon the boss of the wheel p.
The position of the wheel p is controlled by the lever r and the
hauling rope, and it remains stationary so long as the angle at which
the ropes are led away is not altered. The rotation of the wheel q by
the action of the cam groove q¹ against the pulley ¹ raises and lowers
the lever and with it the hauling rope. For each revolution of the
drum the rope is thus moved up or down an amount equal to its own
thickness, the gear o, p, and q being arranged to give this amount of
motion.
""
This winding apparatus admits of the ropes passing on to and from
the drums at any angles, and at angles which are constantly varying,
without in any way interfering with the winding or with the action of
the self-coiling gear, consequently the delay in setting the tackle before
commencing work is reduced to a minimum.
The apparatus is worked by an ordinary farm engine, and one engine
only is required; hence the cost of ploughing tackle including this
winding apparatus is less than most other arrangements of tackle, and as
the hauling rope has never to pass round but one guide pulley in
between the plough or implement and the winding drum there is less
loss of power in friction than with any other winding apparatus capable
of being worked by a single engine.

page_text: What we claim is the construction, substantially as described, of
winding apparatus for ploughing and cultivating by steam power.
In witness whereof, we, the said David Greig and Robert Burton,
have hereunto set our hands and seals, this Twenty-first day of
May, in the year of our Lord One thousand eight hundred and 5
seventy-four.
DAVID GREIG.
