PROVISIONAL SPECIFICATION left by the said John Greenslade at
the Office of the Commissioners of Patents, with his Petition, on,
the 10th April 1874.
I, JOHN GREENSLADE, of Taunton, in the County of Somerset, Engineer,
do hereby declare the nature of my said Invention for "IMPROVEMENTS IN
STEAM PLOUGHING MACHINERY AND IN THE ENGINES EMPLOYED IN WORKING THE SAME,
PART OF SUCH IMPROVEMENTS BEING APPLICABLE FOR OTHER PURPOSES," to be as
follows:-

page_text: reduces the time and manual labour hitherto required in fixing and
working it, and also considerably reduces the wear and tear of the wire
ropes and the machinery in general.
My improved form of detached windlasses I construct so that no
double or single snatch blocks are required to guide the rope on to the
drums, no fixing required into the ground, and it coils its own
rope.
The drums I place in a horizontal position underneath the framing,
following each other in a line with the framing, or by preference one
drum a little to the right and the other a little to the left of the central
line of the framing. I fix four travelling wheels of equal size working
on pivots fixed to the sides of the framing and connect all the wheels to
the shaft draught bar by suitable connecting rods. The shafts on being
turned in either direction will thus cause all the wheels to lock, or two of
the wheels may be fixed rigid and the other two connected to the shaft.
Either of these arrangements admit of the ropes being run off from
the drums in a straight line with the framing, or at any degree up to
right angles without interfering with the road wheels.
By another arrangement I fix the windlass framing on two wheels,
with a third wheel in front of the framing, which will be the stcerage
wheel attached to the shafts. This arrangement admits one rope to run
off from the drum as before described and the other to run off in a liuo
or at right angles.
By another arrangement I supply the framing with three or four
wheels placed outside the ropes when running off at right angles.
When the coiling gear of either windlass is placed over the drums I
fix an iron hoop suspended from the windlass framing, under the lower
drum flange to protect the rope from falling over the flanges. I also
truss the framing from corner to corner over a kind of bridge in the
centre to prevent any twisting of the framing. I also connect the
drum studs together under the drums by a connecting brace. By
these means the strain will be thrown upon both studs when either
or both ropes are working in a line with the windlass. The coiling
gear of the two first-mentioned windlasses may be fixed on the
top of the framing over the drums or underneath them. By placing
it over the drums, it admits of the drums being fixed lower to the ground,
which is more in a line with the draught, and when so arranged I

page_text: transmit motion from the drums to the coiling gear as follows:-On the
top part of the drum I cast or otherwise fix a small spur pinion, which
gears into another of say double its size, the spindle of which passes
through bearings to the top of the framing and then through the
moveable plate that carries the coiling gear, which will be its oscil-
lating centre. This will admit of the coiling gear following the rope at
the angle it may be required to work. To the spindle before mentioned
above the moveable plate I fix a small bevilled wheel, which gears into
another of say double its size, the spindle of which runs in bearings
secured to the moveable plate, which extends out over the framing suffi-
ciently for the coiling bar to properly coil the rope. To the end of this
spindle I fix a small spur pinion of say eight cogs, which gears into
another spur wheel supplied with four times as many teeth as there are
coils of rope required upon the drums (this is a changeable wheel).
As the rope wears it will require more coils of rope to fill the space.
between the flanges. I substitute another wheel having a greater number
of teeth, and continue to do so as required until the rope is completely
worn out. A great saving of rope is thus effected.
The arrangement above described gives two cogs on the changeable
wheel to one round of rope, but it may be speeded so as to move only
one or more as it may be desirable. The moveable wheel is provided
with a slot, and at a suitable distance from its centre, which is about
half the distance between the flanges of the 'drum, I fix a stud, which
passes through a slotted T headed vertical coiling bar, which slides in
bearings in the moveable plate down to the rope, the end of which is
supplied with two small rollers, between which the rope passes.
By another arrangement instead of changing the changeable wheel I
place the stud nearer to the centre, and as the rope wears I continue to
pack the flanges with a plate of iron and wood between sufficient to keep
the rope at say twelve rounds until worn out.
By another arrangement the first motion next the drum being the
same as previously described, but in place of a bevilled wheel in the next
motion I place a spur pinion gearing into another spur wheel of double
its size. This I term an intermediato wheel, and it is supplied with a
small pinion of say eight cogs, which gears into the changeable wheel,
but instead of being vertically placed as previously described I place
it horizontally. Over this wheel I fix to it a cam wheel. The roller of
A 2

an horizontally placed coming lever runs in
coiling lever is fixed to the moveable frame, the other end being supplied
with a vertical bar, rigidly or otherwise, and connected to the rope as
before mentioned.
By another arrangement instead of using the intermediate motion I
provide the second wheel four times the speed of the pinion on the drum
and place the spur pinion which gears into the changeable wheel at the
top of the spindle immediately above the moveable plate and gear direct
into the changeable wheel under the cam.
By another arrangement instead of having a spur pinion gearing into
the changeable wheel, as before mentioned in the first arrangement, I
supply a worm in the place of the pinion gearing into a changeable worm
wheel. The worm is driven as previously described, and speeded as it
may-be desired.
By another arrangement I place the worm wheel horizontally and the
cam wheel over it as previously described in the second arrangement and.
speed it as desired.
Ն
By another arrangement instead of using a bevilled wheel in the
second motion, as described in the first arrangement, I substitute a worm
gearing into a changeable worm wheel placed vertically. An horizontal
coiling lever, as described in the second arrangement, passes by it and is
connected to the stud by a connecting rod or a slot in the coiling lever, or
the changeable wheel may be driven by bevel gear and suitable leverage.
I adjust the coiling by changing the worm wheel or by sliding the
stud nearer to the centre and packing the drum flanges as previously
described. When the coiling gear is placed under the drums it is
carried on the moveable framing, which is secured to the drum stud. A
ring is fixed on the spindle between the drum and moveable framing.
On the moveable frame, and not on the drum stud, I place a cam as
described in the second arrangement, which admits of the coiling being
adjusted, and I transmit motion from the drum by casting or otherwise
fixing to the under side of the drum nave a small spur pinion, which
gears into an intermediate wheel (fixed to the moveable frame) of twice
or four times its speed, which wheel is supplied with a pinion of
suitable size, which gears into the changeable wheel secured to the same.
If the intermediate wheel is twice the size of the drum pinion the.

page_text: drawn tight according to which way the plough is being drawn. At the
top of the framing at the centre or otherwise I place a transverse shaft
having two levers independent of each other. To each lever is secured
a pulley. From each lever over the pulley a piece of wire rope or chain
passes, which is attached to each set of ploughs. From the outward end
of each lever another piece of rope or chain is secured, the other ends
being secured to the stop blocks on the draught chain. As the blocks
are being drawn to and from the fixed bracket one lever will be drawn
down and the other let up, and thus raise one set of ploughs and lower
the other. This arrangement prevents the ploughs in work from jumping
out of the land when crossing ridge and furrow land, the ploughs out of
work being kept entirely suspended by the tight hauling rope. It may be
desirable to couple the two sets of ploughs together to a certain extent
to prevent the ploughs out of work coming too suddenly down on the
land when the plough is stopped. The plough beams are jointed inde-
pendently to the carriage. At the same time the tail rope is drawn at
one side of the frame by a length of rope or chain passing outside the
framing, each end being secured to the hauling rope.
My improved turn-round steam plough, which is intended for
ploughing ridge and furrow land to turn its furrows in opposite directions,
may be thus described :-To accomplish the turning round at the head-
lands I construct the plough with a pair of wheels in front as far apart
from each other as may be most convenient, the wheels to be on the
turntable principle, which admits of their being completely locked
around and the turning round of the plough better accomplished. At a
suitable distance behind the wheels I joint the beam. The part of the
beam carrying the ploughs extends forward from the joints a suitable
distance, then bends downwards in a circular form a suitable distance.
The draught rope is attached to a lever or pulley between the wheels.
From the lever or pulley is attached a piece of rope or chain to the lower
end of the circular bent beam. Another piece also is attached from the
lever or pulley to the hind part of the beam and to the top part of the
wheel spindle that carries the hind part of the plough.
On the hauling
ropo turning round the lever or pulley at the headland it will at the
same time raise the plough out of the land and render it free to turn
round.

page_text: applicable when a wind forward drum is supplied to the anchor, and
consist in so making it that it will wind itself forward by the
hauling rope when tight and not when running slack as heretofore,
and drawing the clutch connected with the pinion that gears into
the drum by a lever coming into contact with one of the tines or.
arms when they drop to penetrate the soil. I also supply the drum
with a ratchet wheel and paul to prevent the rope on the drum
from running out after being wound on when the clutch is drawn.
Instead of making the tines in one piece I make them in two parts.
At the first angle above the point I slot a hole to receive the pointed part
of the tine. At this joint the tines are set to penetrate more or less
into the soil, and I arrange the levers so as to prevent the part between
the angles from passing beyond an horizontal position. By this
arrangement it renders the tincs much casier to raise from out of the
soil.
My improved snatch block I construct of a raised frame to carry the
pulley. By this means the travelling anchors can be drawn closer to the
snatch block at the corner of the field without inconvenience.
My improved claw anchor I construct with three legs instead of two
as heretofore, so that one anchor will be sufficient to hold the snatch
block, which can be set well in the corner.
My improvements in the engine consist of constructing the smoke
box with an external and internal shell the whole width of the smoke
box. Into this space between the shells the feed water is received after
passing the force pump. I employ another pump to receive the water
after passing round the smoke box, heated to a high degree, and forco it
into the boiler, or if a second pump is not used I place a valve in the
smoke box, through which the feed water passes after it has passed com-
pletely round the smoke box, or this valve may be dispensed with as well
as the second pump. In this case a tube is fixed in the smoke box to
convey the water after passing round the smoke box to the boiler.
My improved lubricator I construct as follows:-At the bottom of tho
cup I place a conical valve or plug, which fits into a corresponding seat.
The stem of the valve passes up through the cover, and having a spiral
spring bearing against the valve and cover, a thread is cut on the
valve stem to receive a nut outside the cover. Upon the nut being
screwed down the valve will be raised and adjusted so as to admit of a

page_text: continuous dropping of oil on the bearing. Between the bottom of the
valve and bearing which forms a part of the lubricator is a kind of tube
having an open space to expose the lower part of the valve to view, so
that the attendant may see how fast the oil is dropping and to adjust it
accordingly.
SPECIFICATION in pursuance of the conditions of the Letters Patent,

the 10th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GREENSLADE, of Taunton, in the County of Somerset, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

page_text: TrEENSIAUC & improvemENTS IN DIetem & bowymong wom
performed, to be particularly described and ascertained in and by the
following statement, that is to say :—
My Invention consists of improvements in steam ploughing machinery.
known as the stationary engine or roundabout system, which considerably
reduces the time and manual labour hitherto required in fixing and
working it, and also considerably reduces the wear and tear of the wire.
ropes and the machinery in general.
I. My improved form of detached windlasses I construct so that no
double or single match blocks are required to guide the rope on to
the drums, no fixing required into the ground, and it coils its own
rope.
.
II. The drums I place in a horizontal position underneath the framing,
following each other in a line with the framing, or by preference one.
drum a little to the right and the other a little to the left of the central
line of the framing. I fix four travelling wheels of equal size working on
pivots fixed to the sides of the framing, and connect all the wheels to the.
shaft draught bar by suitable connecting rods. The shafts on being
turned in either direction will thus cause all the wheels to lock, or two of
the wheels may be fixed rigid and the other two connected with the
shafts. When one pair of wheels only is connected to the shafts I
prefer the other pair to be connected to the frame at the centre and free
to oscillate vertically to the framing. Either of these arrangements
admits of the ropes being run off from the drums in a straight line with
the framing, or at any degree up to at right angles without interfering
with the road wheels.
III. By another arrangement I fix the windlass framing on two
wheels, with a third or two wheels in front of the framing, which will be.
the steerage wheel or wheels attached to the shafts. This arrangement
admits one rope to run off from the drum as before described and the
other to run off in a line or at right angles.
IV. By another arrangement I supply the framing with three or four
wheels placed outside the ropes when running off at right angles.
When the coiling gcar of either windlass is placed over the drums I
fix an iron hoop suspended from the windlass framing under the lower
drum flange to protect the rope from falling over tlic flanges. I also
truss the framing from corner to corner over a kind of bridge in the

page_text: centre to prevent any twisting of the framing. I also connect the drum
studs together under the drums by a connecting brace. By this means
the strain will be thrown upon both studs when either or both ropes are
working in a line with the windlass framing.
V. The coiling gear of the windlasses may be fixed on the top of the
framing over the drums or underneath them. By placing it over the
drums it admits of the drums being fixed lower to the ground, which is
more in a line with the draught, and admit the anchors to work close
up to the windlass. And when so arranged I transmit motion from the
drums to the coiling gear as follows:-On the top part of the drum nave
I cast or otherwise fix a small spur pinion, which gears into another, say
double its size, the spindle of which passes through bearings to the top
of the framing, and then through the moveable or alterative plate that
carries the coiling gear, which will be its oscillating centre. This will
admit of the coiling gear following the rope at the angle at which it may
be required to work. To the spindle before mentioned above the
moveable plate I fix a small bevilled wheel, which gears into another of
say double its size, the spindle of which runs in bearings secured to the
moveable plate which extends out over the framing sufficiently for the
coiling bar to properly coil the rope. To the end of this spindle I fix a
small spur pinion of say eight cogs, which gears into another spur wheel
supplied with four times as many teeth as there are coils of rope
required upon the drums (this is a changeable wheel). As the rope
wears it will require more coils of rope to fill the space between
the flanges. I substitute another wheel having a greater number
of teeth, and continue to do so as required until the rope is completely
worn out. A great saving of rope is thus effected. Mitre gear may be
used instead of bevel gear and proper speed attained by reducing the
last pinion, or by an intermediate double wheel placed between pinion
and change wheel.
The arrangement above described gives two cogs on the changeable
wheel to one round of rope, but it may be speeded so as to move only
one or more cogs, as it may be most desirable. The change wheel is pro-
vided with a slot, and at a suitable distance from its centre, which is
about half the distance between the flanges of the drum, I fix a stud,
which passes through a slotted T headed vertical coiling bar, or by a
connecting rod, which slides in bearings in the moveable plate down to

page_text: the rope, the end of which is supplied with two small rollers between
which the rope passes.
VI. By another arrangement instead of changing the changeable
wheel I place the stud nearer to the centre, and as the rope wears I con-
tinue to pack the flanges with a plate of iron and wood between sufficient
to keep the rope at say twelve rounds until worn out.
VII. By another arrangement the first motion next the drum being
the same as previously described, but in place of a bevelled wheel in the
next motion I place a spur pinion gearing into another spur wheel of
double its size. This I term an intermediate wheel, and it is supplied
with a small pinion of say eight cogs, which gears into the changeable
wheel, but instead of being vertically placed as previously described I
place it horizontally. Over this wheel I fix to it a cam wheel. The
roller of an horizontally placed coiling lever runs in the cam. One end
of the coiling lever is fixed to the moveable frame, the other end being
supplied with a vertical bar rigidly or otherwise, and connected to the
rope as before mentioned. The cam and change wheel may be placed
on the drum stud above the frame or to the alterative coiling plate.
By another arrangement instead of using the intermediate motion I
provide the second wheel four times the speed of the pinion on the
drum or other suitable speed, and place the spur pinion which gears into
the changeable wheel at the top of the spindle immediately above the
moveable plate and gear direct into the changeable wheel under the
cam. The pinion gearing into the change wheel by this arrangement
has eight cogs (if the change wheel is arranged to give two cogs for
round of rope). If the first is speeded three to one the pinion will be
of six cogs, or twice four cogs.
VIII. By another arrangement instead of having a spur pinion gearing
into the changeable wheel as before mentioned in the first arrangement
I supply a worm in the place of the pinion gearing into a changeable
worm wheel; the worm is driven as previously described, and speeded as
be desired.
it
may
IX. By another arrangement I place the worm wheel horizontally and

page_text: XIV. On each side of the windlass I place a bracket, which carries
the transverse shaft, which is connected to the engine shaft by a coupling
shaft and universal joint. The transverse shaft carries a pair of bevelled
pinions, which gears into another pair of bevelled pinions. These
pinions are secured to two vertical shafts supplied at their lower ends
with a pair of spur pinions, which gears into cach drum. A pair of
clutches gear into the pinions and are thrown in and out of gear by lever-
arrangement in the usual way. I couple the windlass to the engine by
suitable couplings, but prefer one transverse coupling at or towards the
end of the windlass to the side of the fire-box, and another from the.
other end of the windlass to the smoke box, with a suitable coupling
obliquely from corner to corner or other suitable place. Or the windlass
may be secured to the wheels of the engine by the above or other suit-
able arrangement. No fixing is required from the windlass to the
ground, therefore much time is saved in fixing.
XV. My improved steam plough I construct so as to raise one set of
ploughs out of its work and lower the other set in its work by the
hawling rope. It is carried on three or four travelling wheels secured to
a suitably shaped body, under which at the centre instead of rigidly.`
securing each rope, I fix a bracket, through which I prefer a chain to
pass. At a convenient distance apart on this chain I secure two stop
blocks, one of which will come against the bracket when the rope is.
drawn tight, according to which way the plough is being drawn. At
the top of the framing at the centre or otherwise I place a transverso.
shaft having two levers independent of each other. To each lever is
secured a pulley. From each lever over the pulley a piece of wire, rope,
or chain passes, which is attached to each set of ploughs. From the.
outward end of each lever another piece of rope or chain is secured, the
other ends being secured to the stop blocks on the draught chain. As
the blocks are being drawn to and from the. fixed bracket one lever will
be drawn down and the other let up, and thus raise one set of ploughs.
and lower the other. This arrangement. prevents the plough in work
from jumping out of the land when crossing ridge and furrow land, the
ploughs out of work being kept entirely suspended by the tight hauling
rope. It may be desirable to couple the two sets of ploughs together to
a certain extent to prevent the ploughs out of working coming too
suddenly down on the land when the plough is stopped. The plough
beams are jointed independently to the carriago. At the same time the

page_text: tail rope
is drawn at one side of the frame by a length of rope or chain
passing outside the framing, each end being secured to the hauling
rope.
XVI. My improved turn-round steam plough, which is intended for
ploughing ridge and furrow land to turn its furrows in opposite directions,
may be thus described :-To accomplish the turning round at the head-
lands I construct the plough with a pair of wheels in the front as far
apart from each other as may be most convenient, the wheels to be on
the turntable or forked principle, which admits of their being completely
locked around, and the turning round of the plough better accomplished.
At a suitable distance behind the wheels I joint the beam. The part of
the beam carrying the ploughs extends forward from the joints a suitablo
distance, then bend downwards in a circular form a suitable distance.
The draught rope is attached to a lever or pulley between the wheels.
From the lever or pulley is attached a piece of rope or chain to the lower
end of the circular bent beam, another piece also is attached from the
lever or pulley to the hind part of the beam, and to the top part of the
wheel spindle that carries the hind part of the plough. On the hauling
rope turning round the lever or pulley at the headland it will at the same
time raise the plough out of the land and render it free to turn round.
XVII. My further improvements in my self-acting anchor, for
which I have received Royal Letters Patent, dated December Twenty,
One thousand eight hundred and seventy-one, No. 3443, are applicable
when a wind-forward drum is supplied to the anchor, and consist
of in so making it that it will wind itself forward by the hauling rope
when tight, and not when running slack as heretofore, and drawing
the clutch connected with the pinion that gears into the drum by a lever
coming into contact with one of the tincs or arms when they drop to
penetrate the soil. I also supply the drum with a ratchet wheel and
paul to prevent the rope on the drum from running out after being
when the clutch is drawn.
wound on,
Instead of making the tines in one piece I make them in two parts.
At the first angle above the point I slot a hole to receive the pointed
part of the tine. At this joint the tines are set to penetrate more or
less into the soil, and I arrange the levers so as to prevent the part
between the angles from passing beyond an horizontal position. By this
arrangement it renders the tines much easier to raise from out of the
soil

page_text: XVIII. My improved snatch block I construct of a raised frame to
carry the pulley. By this means the travelling anchors can be drawn
closer to the snatch block at the corner of the field without incon-
venience.
XIX. My improved claw anchor I construct with three legs instead of
two as heretofore, so that one anchor will be sufficient to hold the snatch
block, which can be set well in the corner.
XX. My improvements in the engine consist of constructing the
smoke box with an external and internal shell the whole width of the
smoke box. Into this space between the shell the feed water is received
after passing the force pump. I employ another pump to receive this
water after passing round the smoke box and heated to a high degree,
and force it into the boiler, or if a second pump is not used I place a
valve in the smoke box, through which the feed water passes after it has
passed completely round the smoke box, or this valve may be dispensed
with as well as the second pump. In this case a tube is fixed in the
smoke box to convey the water after passing round the smoke box to the
boiler.
XXI. My improved lubricator I construct as follows:-At the bottom
of the cup I place a conical valve or plug, which fits into a corresponding
scat. The stem of the valve passes up through the cover, and having a
spiral spring bearing against the valve and cover. A thread is cut on
the valve stem to receive a nut outside the cover. Upon the nut being
screwed down the valve will be raised and adjusted so as to admit of a
continuous dropping of oil on the bearing. Between the bottom of the
valve and bearing which forms a part of the lubricator is a kind of tube
having an open space to expose the lower part of the valve to view so
that the attendant may see how fast the oil is dropping, and to adjust it
accordingly.

page_text: Figure 14 is a side elevation and Figure 15 a front elevation partly in
section of my improved smoke box as described in Section XX. 5 shows
the water space the width of the smoke box; and 6 shows water space
between internal and external shell; 7, inlet pipe from pump; and 8,
the pipe conveying the water from the water space to the boiler.
At O, Figure 14, is illustrated a coiling gear as described in Sections VII.
and IX., the same letters of reference apply, the difference being that all
the gearing next the drum pinion is placed on the alterative framing.
It is the double arrangement of gearing shown. In the single arrange-
ment e gears into b.
Figure 16 is a plan of the coupling between windlass and engine as
described in Section XIV., 9 being braces which hold the windlass in
position when the ropes are working at right angles from it; 10 are
braces holding the windlass in position; when the ropes are working in
a line with the windlass tightening screws are provided.
Figure 17 is an improved snatch block as described in Section XVIII.
Figure 18 is an elevation of my improvements in the anchor as
described in Section XVII. 11 shows a mortice in the tine bar for
adjusting the depth of the hold of tine 12; 13 are connections from the
clutch box to the tine bar.
Figure 19 represents lubricator as described in Section XXI., 14 being
valve; 15, valve spindle showing spiral spring; 16, nut outside
cover.
The ropes are thus indicated
in all the Drawings.
What I claim as secured to me by the herein-before in part recited
Letters Patent is,―
Firstly. The fixing of the road steering wheels to the sides of the
framing, and connecting the same by levers to the shaft draught bar,
and fixing the hind wheels to the framing at the centre, see Drawings I.,
II., III., and IV.
2. The fixing the road wheels as and for the purposes described in
Sections III. and IV., and Figures 6 and 12.
3. The fixing of the drums of stationary detached windlasses under-
neath the framing.
4. The different arrangements herein contained for driving the coiling

page_text: cams and levers, and method of adjusting the same, or any modi-
fication thereof.
5. The fixing of the coiling cams and gearing to the alterative coiling
framing.
6. The coiling arrangements as being applicable to any other kind of
winding drums besides those used in steam ploughing.
7. Packing the drum flange or flanges so as to keep the rope at a
given number of coils irrespective of its size, see Figure 12 in the
Drawings at N.
8. The arrangement for raising one set of ploughs and lowering the
other, and drawing the slack rope at one side of the framing by the
hauling rope.
9. The construction of turn-round ploughs with the front wheels on
the turntable or forked principle.
10. The winding forward of the anchor by the hauling rope when
tight instead of by by the slack rope as heretofore. The construction of
the tines as described, and the arrangements for driving the clutch
connected to the winding drum.
11. The coupling of the windlass to the engine in the manner
described (see Fig. 16).
12. The construction of snatch blocks with a raised frame for the
purposes herein described, and constructing claw anchors with three
claws instead of two.
13. The construction of the smoke boxes of the engines with an internal
and external shell, as and for the purposes described.
14. The construction of lubricators with a conical valve at the bottom,
and method of adjusting the same.
In witness whereof, I, the said John Greenslade, have hereunto
