I, JOHN REEVE LAVELL, of 21A, Old Change, in the City of London, Solicitor,
do hereby declare the nature of this invention (a communication to me by William
Humphrey Perrin, of Smith's Falls, in the County of Lanark, in the Province of
Ontario, Dominion of Canada, Gentleman,) to be as follows:-
This invention relates to sulky-ploughs and it comprises the improvements
hereinafter described.
In a plough provided with my improvements the plough beam which may be
adapted to carry one or more plough bodies is of ordinary construction and has a
seat for the driver fixed upon it.
The beam is at the front attached to a cross axle by a yoke which is provided
with eyes through which the said axle passes, the rear end of the said beam being
supported by a follower wheel journalled in a depending fork pivoted to the beam,
and having an arm formed on its upper end and connected by a rod to a lug formed
on the yoke in such a manner that any movement imparted to the front axle for
steering the plough is communicated to the follower wheel in the desired manner.
A draught pole is attached to the front axle between the arms of the yoke.
A lever hereinafter referred to as the lifting lever is fulcrummed to the beam and
provided with a spring catch adapted to engage a toothed segment, this lifting
lever being connected by a rod to an arm rigidly secured to the front axle.
This front axle has an arm rigidly secured to it at each end, the
arm on the furrow side being shorter than the one on the land side and carrying
a larger wheel. A hook is secured to the furrow end of the front axle and is con-
nected by a chain to the lower end of the lifting lever which projects below the
beam in such a manner that when the lever is in position to hold the plough body
or bodies out of work the chain is loose whilst when the plough bodies are lowered
into work the chain is more or less wound upon the front axle and tightened
thereby preventing the relative movement of the beam and front axle.
Another lever hereinafter referred to as the pole adjusting lever is fulcrummed
on one end of a rod the other end of which is secured to the yoke and is operated
in an approximately horizontal plane, the short arm of this lever being connected
by a rod to the tongue pole. A toothed segment secured to the front axle near
the land side end is engaged by a spring catch and holds the. lever in whatever
position it may be set.
With the construction herein before described when the lifting lever is pulled
towards the driver the front axle is turned in the yoke so that the arms carrying
the wheels are perpendicular, thus raising the front end of the beam and carrying
the plough body or bodies clear of the ground; the chain in connection with the
lifting lever is also slackened thereby allowing the front axle to be turned from its
normal position, which is at right angles to the pole to facilitate the turning of
the implement the follower wheel owing to its connection with the front axle also
being moved to further facilitate the turning. When, however, the lever is

page_text: pushed forward or away from the driver, the plough again enters the ground the
chain being drawn tight, thus rigidly connecting the plough beam and the axle.
When it is necessary for the horses to turn while the plough is in the ground,
as for instance at the end of a bout, the pole lever is disengaged from the toothed
segment and thus allows the pole to be turned while the plough continues to go 5
straight on. The depth of the plough in the ground is regulated by the lifting
lever.

I, JOHN REEVE LAVELL, of 21A, Old Change, in the City of London, Solicitor,
do hereby declare the nature of this invention (a communication to me by William
Humphrey Perrin, of Smith's Falls, in the County of Lanark, in the Province of
Ontario, Dominion of Canada, Gentleman,) and in what manner the same is to
be performed, to be particularly described and ascertained in and by the follow-
ing statement:
-
This invention relates to sulky-ploughs and it conprises the improvements
hereinafter described.
In the accompanying drawings,
Figure 1 is a side elevation of a sulky-plough having my improvements applied
thereto; and,
Figure 2 is a plan of the same:
Figure 3 is a section on the line 3-3 Figure 2.
In a plough provided with my improvements the plough beam a (which as
shewn in the drawing is only adapted to carry one plough body a¹ but which
may be adapted to carry several plough bodies) is of ordinary construction and
has a seat a for the driver fixed upon it.
b is a yoke which is pivoted at 61 to the beam and which is provided with two
eyes c, c through which a cross axle d passes, the said axle having at its two ends
the lever arms e, e¹ carrying the axles for the land and furrow wheels f, fl
respectively, the latter being the larger and having its arm el shorter than the
arm e as clearly shewn in Figure 1. These arms are secured to the cross axle d
by clips which permit of varying the position of the said arms to suit the width
of furrow being ploughed and also permit of varying the angular position of the
said arms relatively with one another according to the depth of furrow.
g is a follower wheel at the rear end of the beam the axle of which wheel is
carried by a forked standard g¹ adapted to be rotated on a pin go on the plough
beam; to the standard g¹ is fixed an arm 92 which is connected by a rod g³ to a
lug or arm g formed upon the yoke b, whereby any steering movement imparted
to the cross axle d through the draught pole h will be communicated to the wheel g
thereby enabling the plough to be turned much more readily than if the standard
of the wheel g was a fixture.
A lifting lever is pivoted to the beam a at i¹ and has a spring catch working
in conjunction with a toothed segment 23 whereby the lever may be fixed in any
desired position. This lever ¹ is connected by a rod i to an arm 25 rigidly secured
to the front axle and the adjustment of this lever i serves to. more or less rotate
the cross axle d and thereby to raise or lower the wheels f, f¹ relatively with the

page_text: beam and the plough body so as to lift the latter entirely out of the ground, as
shewn in Figure 1, or to allow it to work at a greater or less depth.
The lever i is provided with an extension j from the free end of which exten-
sion a chain k extends to a hook or catch on the axle d; the catch is pre-
ferably in the form of two lugs with a space between them into which the links
of the chain can be introduced sideways, as clearly shewn in Figure 2, so as to
permit of adjusting the length of the chain. In practice this chain is so adjusted
that when the lever i is in position to hold the plough body or bodies out of work
the chain is loose, as shewn in Figure 1, so that the front axle can be locked or
turned in either direction to permit of manoeuvring the plough, whilst when the
plough body is lowered into its work the said chain will be more or less wound
upon the axle and tightened thereby preventing the pressure upon the plough
body from forcing the latter in the direction of the arrow, Figure 2, as would be
the case if means were not provided for holding the plough beam rigid in this
direction relatively with the cross axle d and the pole h.
In order to permit of adjusting the angle of the pole h relatively with the cross
axle d I provide the following arrangement, that is to say, to the arm g of the
yoke b I attach one end of a rod the other end of which rod serves as the ful-
crum of a pole adjusting lever m. This lever m which is arranged in an approxi-
mately horizontal position, as shewn clearly in Figures 1 and 3, has one end
adapted to serve as a handle whilst the other end is connected at m' to a bracket m³
free to slide upon the cross axle d, as shewn in Figure 3. This bracket m² is con-
nected by a rod m³ to the pole h. With this arrangement it will be understood
that the movement of the lever m in one or the other direction causes the angular
movement of the pole in the required manner, the connection between the pole
and the axle d being sufficiently loose to permit of this angular movement.
A toothed segment n in connection with the bracket m² and a spring catch n¹
in connection with the lever m serve for locking the said lever in any position to
which it may be adjusted.
With the construction herein before described it will be understood that when
the lifting lever is in the position shewn in Figures 1 and 2 the cross axle is in
the position in which the arms carrying the wheels are substantially perpendicular,
so that the plough body runs clear of the ground, the chain & being also slackened
to allow of the front axle turning from its normal position to facilitate the turn-
ing of the implement the follower wheel owing to its connection with the front
axle by the rod g being also moved to further facilitate the turning. When,
however, the lever i is pushed forward or away from the driver, the plough is
lowered to again enter the ground the chain k being at the same time drawn
tight owing to its being more or less wound upon the axle d in order to rigidly
connect the plough beam and axle in the manner hereinbefore referred to.
In order that the plough at the end of each bout may be run as close up to the
boundary as possible to reduce the width of the headlands to a minimum the
lever m is disengaged from the segment so as to allow the pole to assume a greater
or less angle relatively with the plough.
In practice I prefer to provide my plough with a coulter p which can be rocked
to remove any obstruction or which will automatically rock when the plough is
backed; as shewn in the drawing the coulter is of the kind described in the
Specification of my application No. 24144 of even date with this application.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a sulky-plough the combination with the beam of a cross axle pivoted
to the said beam and adapted to be rotated to raise and lower the plough by means
of a lever, and of a chain or the like connected with an extension of the said lever
and with a clip upon the said cross axle in such a manner that when the plough
is in work the said chain will be taut, substantially as described.

page_text: 2. In a sulky-plough having a cross axle which is pivoted to the plough beam,
a follower wheel arranged to pivot upon a more or less vertical axis and connected
with the cross axle in such a manner that any steering movement imparted to the
said cross axle will also be imparted to the follower wheel, substantially as
described.
3. In a sulky-plough, a draught pole loose or pivotally connected with the
cross axle and a lever and rod adapted for altering the angle of the pole relatively
with the said cross axle and retaining it in any position, substantially as
described.
4. In a sulky-plough the combination of a cross axle pivotally connected with
the plough beam, a follower wheel at the rear end of the beam connecting with
the cross axle in such a manner that any steering movement imparted to the one
axle is transmitted to the follower wheel, a pole capable of angular movement
relatively with the cross axle and means for adjusting the angle of the pole, sub-
stantially as described.
5. The manufacture and use of the improved sulky-plough constructed, arranged
and operating substantially in the manner hereinbefore described and illustrated
in Figures 1, 2 and 3 of the accompanying drawings.
