Improvements in Carriage and Sulky Ploughs.
A communication from COCKSHUTT PLOW COMPANY, of Brantford, Canada.
I, Alfred JulIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
-
The object of the invention is first to so connect the front carriage of the plough
to the tongue that it may be readily set by the driver to guide the plough to the
right or left independently of the team and while the plough is in operation, so that
any unevenness in the furrow may be straightened out and also so that the tongue
may be adjusted on the bail to suit the draft of two or three horses as may be
necessary; secondly, to so arrange the plough that although the swaying of the
pole by the horses while ploughing a furrow will not affect the plough beam, yet
the plough may be readily turned when desired, and thirdly, to arrange the
mechanism for raising and lowering the plough-beam so that it may be operated
from the driver's seat, and it consists essentially first, in pivotting the rear end of
the tongue to the rear portion of the bail of the front carriage of the plough and
adjustably connecting the front portion of the bail to the tongue a short distance
forward of its rear end, the hand-lever operating the adjusting mechanism being
carried rearwardly to a point in reach of the operator; secondly, in pivotting the
front carriage to the plough beam and limiting its motion by chains connected
respectively to the front and rear portions of the plough beam and in so connecting
the rear furrow wheel to the plough that it may be converted into a castor-wheel
when it 18 desired to turn, and thirdly in removing the hand-lever from the top of
the eccentric to which it has formerly been attached and bringing it back on the
plough beam within reach of the driver's hand and connecting it to the eccentric
by suitable means, substantially as hereinafter more particularly explained.
The drawing shows a perspective view of the improved plough.
A is the tongue which is pivotally connected as shown to the rear bar B, of the
bail C, which is connected to the front plough carriage D, which is of ordinary
construction and need not be further described here.
On the tongue a short spindle E is pivotted. To the upper end of this spindle a
hand-lever F, is rigidly connected. On the lower end of the spindle E a short
arm G is rigidly connected which arm G is connected by a link H to the lug I
adjustably connected to the front bar J of the bail. A guide K embraces the front
bar of the bail and is suitably connected to the underside of the tongue. From this
connection it will be readily seen that by shifting the hand-lever F the angle of the
bail in reference to the tongue may be readily altered, a suitable notched quadrant L
being provided to hold the lever in any desired position. As the bail C is connected
to the front carriage of the plough, the motion of the said bail is necessarily con-
veyed to it and the plough guided to the right or left as may be found necessary in
straightening the furrow.
It will be noticed that the lower end of the pivot bolt of the tongue forms a clasp
embracing the rear bar B of the bail so that by loosening the nut of the said bolt
the tongue may be shifted to the right or left to suit the number of horses being
used, while the lug I is also adjustable on the front bar J of the bail so that it may
be set to correspond with the position of the pivot bolt of the tongue.
To the plough beam M a king-bolt N is rigidly connected and on this king bolt
the front carriage of the plough is pivotted as indicated. On the plough beam the
eccentric O. is pivotted at a, its lower side bearing on a plate connected to the axle
of the front plough carriage. A short arm P, is rigidly connected to 'the upper

page_text: side of this eccentric. On the plough within convenient reach of the driver's seat
a hand-lever Q is pivotted, provided with a suitable notched quadrant which hand-
lever is connected by the link R to the arm P; thus when the hand-lever Q is
moved the eccentric is rocked and the plough beam raised or lowered by the
action of the eccentric on the carriage D the king-bolt sliding through the bearings
formed on the said carriage.
It will be noticed that the rear furrow wheel S is shaped to act as a land-side.
The said rear furrow-wheel is pivotted on the lower end of the spindle T, the upper
end of which is vertically journalled on the rear end of the plough-beam. The
lower end of this spindle it will be noticed,-turns rearwardly so as to adapt the said.
rear furrow-wheel for use as a castor-wheel when it is desired to turn the plough.
On the upper end of this spindle a collar U is formed, having suitable recesses to
receive one or more pins V projecting from the lower side of the pivotted lever W,
a suitable spring being provided to hold the said pins in engagement with the
collar U. It will be observed that this lever is so situated that it may be readily
operated by the foot of the driver and the rear furrow-wheel left free to act as a
castor-wheel. The journal of the said rear furrow-wheel is bushed and provided
with cone bearings so that any wear my be readily taken up.
It will be noticed that the axle of the front carriage of the plough is connected
by the chains b to the front and rear portions of the plough beams respectively
which chains limit the free movement of the said carriage as is necessary in
turning the plough and at the same time are sufficiently slack to admit of the said
carriage being swayed to a limited extent by the action of the horses and also in
the operation of straightening the furrow as previously described.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondents, and in what manner the
same is to be performed, I declare that what I claim is ;-
1. In a riding plough a front carriage having a bail pivotted to the tongue in
combination with means whereby the horizontal angle between the tongue and front
carriage may be readily altered substantially as and for the purpose specified.
2. In a riding plough the tongue A pivotted to the rear bar B of the bail C of
the front carriage D in combination with the hand-lever F pivotted to the tongue
and rigidly connected to the arm G which is flexibly connected to the front of the
bail substantially as and for the purpose specified.
3. In a riding plough the front plough carriage pivotted on the plough beam in
combination with means to limit the sway of the plough carriage substantially as
and for the purpose specified.
4. In a riding plough the front plough carriage D pivotted on the plough
beam M in combination with slack chains 6 connecting the axle of the plough
carriage to the front and rear portions of the plough beam. substantially as and for
the purpose specified.
5. In a riding plough the front plough carriage pivotted on the king bolt N in
combination with the eccentric E pivotted on the plough beam the said eccentric
having a short arm P projecting therefrom connected by a link R to the hand-
lever Q pivotted on the plough beam close to the driver's seat substantially as and
for the purpose specified.
6. In a riding plough the rear-furrow-wheel S swivelled on the plough beam M
in combination with a front plough carriage D pivotted on the said plough beam
and connected to the front and rear portions of the plough beam by means of slack
chains substantially as and for the purpose specified.
7. In a riding plough a rear furrow-wheel journalled on a spindle swivelled on the
plough beam in such a manner that it is capable of turning freely in a horizontal
plane in combination with a lever pivotted on the plough beam close to the driver's
seat one end of the said lever being adapted to engage with the said spindle or a
collar formed thereon so that the said spindle may be held from revolving substan-
tially as and for the purpose specified.
