1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.1.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows :-
This invention has for its object the employment, in ploughs, and ridging
ploughs of rotating discs peculiarly arranged with or without coulter or sole or
ordinary plough bodies. By this means the drawbacks which have become
apparent in the use of articles with fixed blades particularly in ridging up and
cultivating potatoes are avoided. The compression of the soil and the choking
of the apparatus on weedy ground, or where long or short manure has been
ploughed in, are also avoided.
On well cultivated ground a coulter is unnecessary but it is required on ground
which is not so well cultivated, and, according to the character of the soil, must
be replaced by a grubber foot or even by a ploughshare. A large number of
modifications are developed from this improvement, some of which will now be
more particularly described in combination with the peculiar rotary disc.
The characteristic points of the rotating disc are, first, the method in which it is
attached to its framework so as to be adjustable in all directions, and further the
arrangement of its supporting parts, to the perch in such a way as to be free to
oscillate, so that the disc can suit itself to all unevenness of the ground. This
action may be increased by loading the hanging attachment parts with weights.
On the accompanying drawings
Figures 1 and 2 are respectively an elevation and plan view of a potato earthing
up apparatus ;
Figures 3-6 are details of Figures 1-2;
Figures 7-12 are modifications of the arrangement of the rotary discs with
their setting mechanism;
Figures 13-14 show an elevation and plan view respectively of a plough with
rotary mould board;
Figure 15 shows a modified form of construction of the rotary disc.
In the apparatus for earthing up potatoes, shown in Figures 1-2, levers B are
movably attached to the perch A by means of pins a. Levers C are adjustably
arranged in the holders or bushes B₁ of these levers B, and are fixed by means of
screws bb. On each of the levers C which may be U-shaped, see Figures 3 and 4,
there is a clamp cap c which serves for receiving a shank or arm D, this latter
being firmly fixed in the cap e by tightening the screw d. The rotary disc E is
arranged on the arm D. The shank or arm D (Figure 5) is provided with a
collare and groove, in which latter engages a screw g, which is seated in the
nave F of the disc E. As the lever B is movably connected to the perch A,
the former can oscillate and with it also the disc seated thereon. The latter may
again be adjusted by pushing forward and turning the lever C in the socket B', and
further the clamp cap c admits of the shank D being turned and drawn up or down.

page_text: If the discs are further to be approached or separated, the pins a, Figures 1 and 2,
may be made in the form of an axle passing right through.
If the lever C be made in the form of a flat iron bar, a U-shaped piece his
placed round the disc bar D in the clamp cap c, Figures 5 and 6. This form of con-
struction is completed by the insertion of a wedge A', and it admits of exactly the
same adjustments as the device shown in Figures 3 and 4.
Figure 7 shows a further setting device for the discs. A bent piece G is
attached to the perch A by means of screws. A spindle I revolving in
sockets H H can simultaneously oscillate, as the socket or bush H is movably
attached to the lower end of the bent piece G, whilst the socket or bush H¹
may be fixed to the upper shank of the bent piece G by means of known devices.
The adjustment of the spindle takes place by means of the handle K, which rests
against a curved bar K. A bush i which may be shifted and fixed is arranged on
the spindle I which is preferably made rectangular, and the rotary disc E is seated
on this bush. Finally, another modification may be obtained by flattening the disc
arm D, Figures 9-11. A recessed support or bearing L is seated on the perch A,
and the flattened shank D rests against this support. The plate & rests against the
flat side of the bar D, whilst the projections on the support L prevent a lateral
displacement of the bar. By strongly tightening up one or other of the lug
screws M M, the lugs of which engage over pins m m of the plate k, the latter is
drawn towards the support L, by which means the bar D is held fast. The bar is
shifted by tightening or loosening the screw; as the bar may also be adjusted as
desired in the direction of its height, it is possible with this form of construction to
impart to the rotary discs any desired position.
As shown in Figure 12 the rotating discs E may also be arranged in pairs on a
single oscillating lever A', which is bent to correspond to the number of discs.
Figures 13 and 14 show the arrangement of a rotating disc E in combination with
a ploughshare O serving as a coulter. The disc E has teeth or spikes n on its
periphery, in order that, by these teeth n engaging in the ground, the forward
motion of the plough may be better transferred to the disc E and set the latter in
regular rotation. In order that the action of the disc E, as regards disintegrating,
mixing and turning the ground, may rightly come into play, the scraper plate
shortened, and consequently the disc E delivers the soil, as soon as it is scraped off,
for further treatment. The setting or adjusting mechanism of this plough with
rotary scraper is as follows:-
◊ IS
The toothed sector P, in the teeth of which the spindle p engages, is hinged to
the perch A of the plough. The ploughshare may be adjusted up or down as may
be desired by screwing the spindle up or down, and it may be fixed in any position
by means of a small screw 9' provided with a triangular head, and which presses
against the sector. A lever is adjustably arranged in two holders Q Q on the
toothed sector P, which lever serves for receiving the rotary disc E. As however
it is necessary that the rotary disc shall be adjustable in every direction, it cannot
be directly attached to the lever q, but some fixing devices must still bo
intercalated.
A handle R is movably seated on the pin g" of the lever g, and can rest firmly
in the bent piece or loop Ŕ'. A second handle S is hinged to the pin r on a lug of
this handle R as shown in Fig. 14, which may be fixed in a loop S¹. The shaft of
the rotating scraper plate E is finally attached to this handle S. With this plough
it is possible to adjust the ploughshare simultaneously with the rotating pronged
disc, and also to further adjust the disc separately.
The disc may as shown in Figure 15 be arranged in such a way that the
segments E' E' which are provided with teeth or spikes n n are interchangeabie.

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in
the County of Middlesex, Civil Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention has for its object the employment, in ploughs, and ridging
ploughs, of rotating discs peculiarly arranged with or without coulter or sole or
ordinary plough bodies. By this means the drawbacks which have become
apparent in the use of articles with fixed blades particularly in ridging up and
cultivating potatoes are avoided. The compression of the soil and the choking
of the apparatus on weedy ground, or where long or short manure has been
ploughed in, are also avoided.
On well cultivated ground a coulter is unnecessary but it is required on ground
which is not so well cultivated, and, according to the character of the soil, must be
replaced by a grubber foot or even by a ploughshare. A large number of
modifications are developed from this improvement, some of which will now be
more particularly described in combination with the peculiar rotary disc.
The characteristic points of the rotating disc are first, the method in which it is
attached to its framework so as to be adjustable in all directions and further the
arrangement of its supporting parts, to the perch in such a way as to be free
to oscillate so that the disc can suit itself to all unevenness of the ground. This
action may be increased by loading the hanging attachment parts with weights.
In the drawings accompanying the Provisional Specification-
•
Figures 1 and 2 are respectively an elevation and plan view of a potato
earthing up apparatus ;
Figures 3-6 are details of Figures 1-2;
Figures 7-12 are modifications of the arrangement of the rotary discs with
their setting mechanism;
Figures 13-14 show an elevation and plan view respectively of a plough with
rotary mould board;
Figure 15, shows a modified form of construction of the rotating disc.
In the apparatus for earthing up potatoes, shown in Figures 1-2, levers B are
movably attached to the perch A by means of pins a. Levers C are adjustably
arranged in the holders or bushes B' of these levers B, and are fixed by means
of screws 6 b. On each of the levers C which may be U-shaped, see Figures 3
and 4, there is a clamp cape which serves for receiving a shank or arm D, this
latter being firmly fixed in the cap c by tightening the screw d. The rotary
disc E is arranged on the arm D. The shank or arm D (Figure 5) is provided
with a collar e and groove f, in which latter engages a screw g, which is seated in
the nave F of the dise E. As the lever B is movably connected to the percb A,
the former can oscillate and with it also the disc seated thereon. The latter may
again be adjusted by pushing forward and turning the lever C in the socket B₁,
and further the clamp cap c admits of the shank D being turned and drawn up or
down. If the discs are further to be approached or separated, the pins a,
Figures 1 and 2, may be made in the form of an axle passing right through.

page_text: is
If the lever C be made in the form of a flat iron bar, a U-shaped piece
placed round the disc bar D in the clamp cap c, Figures 5 and 6. This form of
construction is completed by the insertion of a wedge ', and it admits of exactly
the same adjustments as the device shown in Figures 3 and 4.
Figure 7 shows a further setting device for the discs. A bent piece G is
attached to the perch A by means of screws. A spindle I revolving in
sockets H H can also oscillate on its socket H, as the socket or bush H is
movably attached to the lower end of the bent piece G. whilst the socket or
bush H may be fixed to the upper shank of the bent piece G by means of known
devices. The adjustment of the spindle takes place by means of the handle K,
which rests against a curved bar K. A bush i which may be shifted and fixed
is arranged on the spindle I which is preferably made rectangular, and the rotary
disc E is seated on this bush. Finally, another modification may be obtained by
flattening the disc arm D, Figures 9-11. A recessed support or bearing L is
seated on the perch A, and the flattened shank D rests against this support.
The plate k rests against the flat side of the bar D whilst the projections on the
support L prevent a lateral displacement of the bar. By strongly tightening up
the eye bolts M M, the eyes of which engage over pins m m of the plate k, the
latter is drawn towards the support L, by which means the bar D is held fast.
The bar is shifted by tightening or loosening a screw N; as the bar may also be
adjusted as desired in the direction of its height, it is possible with this form of
construction to impart to the rotary discs any desired position.
As shown in Figure 12, the rotating discs E may also be arranged in pairs on
a single oscillating lever A', which is bent to correspond to the number of discs.
Figures 13 and 14 show the arrangement of a rotating disc E in combination with
a ploughshare O serving as a coulter. The disc E has teeth or spikes n on its
periphery, in order that by these teeth n engaging in the ground the forward
motion of the plough may be better transferred to the disc E and set the latter in
regular rotation. In order that the action of the disc E, as regards disintegrating,
mixing and turning the ground, may rightly come into play, the scraper plate
is made somewhat shorter, and consequently delivers to the rotary disc E for
further treatment the soil, which has been ploughed up. The setting or adjusting
mechanism of this plough with rotary breaking up disc is as follows:-
The toothed sector P, in the teeth of which the spindle p engages, is hinged
to, the perch A of the plough. The ploughshare which is suitably attached to
said sector may be adjusted up or down as may be desired by screwing the spindle
up or down, and it may be fixed in any position by means of a small screw g',
provided with a triangular head, and which presses against the sector. A lever g
is adjustably arranged in two holders QQ on the toothed sector P, which lever
serves for receiving the rotary disc E. As however it is necessary that the rotary
disc shall be adjustable in every direction, it cannot be directly attached to the
lever 9 but some fixing devices must still be intercalated.
A handle is movably seated on the pin ql of the lever q, and can rest firmly
in the bent piece or loop R¹. A second handle S is hinged to the pin on a lug
of this handle R, as shown in Figure 14, which may be fixed in a loup S¹. The
shaft of the rotary disc E is finally attached to this handle S. With this plough
it is possible to adjust the ploughshare simultaneously with the rotating pronged
disc, and also to further adjust the disc separately. The disc may as shown
in Figure 15 be arranged in such a way that the segments E¹ E which are
provided with teeth or spikes n n are interchangeable.
Having now particularly described and ascertained the nature of the said iuven-
tion and the manner in which the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is :-
1. Improved rotary discs E, with smooth or spiked periphery, for ploughs,
earthing up or ridging apparatus, and the like, characterised by the said dises
being capable of adjustment in a horizontal or vertical direction, or even at an

page_text: angle to the attachment perch or lever by means of suitable mechanicnt
contrivances, substantially as described and illustrated.
2. The arrangement of the rotating discs described in Claim 1, behind a fixed
coulter, substantially as described and illustrated.
3. The arrangement of the discs described in Claim 1, in hinged or pivoted
connection separately or in pairs with the lever perch or frame which carries them
n order to produce an oscillation of the same or a better engaging of the discs in
the ground, Figure 1, substantially as described and illustrated.
4. The arrangement of the discs E described in Claim 1 in combination with a
ploughshare O, the scraper o of which may be suitably shortened, whilst the
oscillating lever B with its special angular positions may be wholly, or only
partially, dispensed with, Figures 13 and 14, substantially as described and
illustrated.
5. In the arrangement described in the preceding claim, the use of a spindle p
by means of which the toothed sector P, carrying the ploughshare 0 and the
rotating disc E, inay be adjusted, so that the depth of penetration of the plough
may be regulated, substantially as described and illustrated.
6. An adjusting device for the rotating discs described in Claim 1, consisting of
the single or multiple hinged attachment of the disc E with the perch A, whilst
the separate hinged connections may be provided with handles for fixing them by
means of known contrivances, see Figures 13 and 14, substantially as described and
illustrated.
7. The mode of fastening the bars of the discs described in Claim 1 by means of
clamp caps c, U-shaped pieces and screws with or without wedges A', sub-
stantially as described and illustrated.
8. The connection of the naves F of the rotating discs E, described in Claim 1,
with the bar D, by providing the horizontal shank of the bar D with a recess in
which engages a set-screw 9 seated in the nave of the disc E, substantially as
described & illustrated.
9. The connection of the adjusting device described in Claim 3 with the
perch A or lever B by means of a holder or bush B' integral with the lever B, and
a tube C of suitable section adjustable therein, substantially as described and
illustrated.
10. The modification of the connection described in Claim 3 of the rotating
disc E with the perch A consisting in a swinging and revolving but fixable bar!
being arranged in a bent piece G adjustable on the perch or frame, on which bar I
a block i carrying the rotating disc may be adjustably arranged, substantially as
described and illustrated.
11. The further modification of the connection described in Claim 3, of the
rotating disc E with the perch A or the like, in such a way that the disc bar D,
seated in the bearing and which may if desired be somewhat flattened, is pressed
by means of a clamp plate k against the fastening (attachment) beam or perch,
whilst an adjustment to a vertical angle may be effected, by means of a pressure
screw N, substantially as described and illustrated.
