DRAINING AND CULTIVATING LAND.

ments attached thereto, over the ground. 
Of course it will be seen that the rotation of 
the barrels may be reversed by sliding the 
clutches into the opposite mitre wheels. 
In order to work the ploughs or other 
implements, I first place the auxiliary car- 
riages at convenient distances from the 
principal or locomotive carriage, and parallel 
therewith, as shown in fig. 8, and then 
make fast one end of a rope, band, or chain, 
to each of the barrels r, r, on the locomotive 
carriage. I then coil thereon a quantity of 
the rope, band, or chain, sufficient, when 
uncoiled, to extend from the principal to the 
auxiliary carriages. I then stretch out a 
continuation of such ropes, bands, or chains, 
to, and pass them round the pulleys or 
drums t, on the auxiliary carriages, bring- 
ing the ends back to the main carriage, and 
there make them fast to the barrels in 
such a way that when the barrels revolve, 
the rope, band, or chain, may travel round 
the pulleys of the auxiliaiy carriages, one 
end of the ropes, bands, or chains, coiling 
on the barrels r, whilst the other ends are 
uncoiling therefrom. 
To these track ropes, bands, or chains, I 
attach ploughs, or other agricultural imple- 
ments, and then (the steam-engine being at 
work) I throw the barrels r, into gear by 
means of the clutch boxes s, s, which will 
cause the ropes, bands, or chains, to travel 
over the spaces of ground between the main 
carriage, and the auxiliary carriages drawing 
the ploughs or other implements through or 
over the ground in the line or space com- 
prised between the principal and auxiliary 
carriages. 
When the plough or other implement 
shall have been drawn out to the required 
distance, it may be turned round by an at- 
tendant at the auxiliary carriage, and the 
barrel r, be made to revolve in an opposite 
direction, so as to cause the plough or other 
implement to be drawn back again towards 
the principal carriage. 
It is evident that the train of wheels and 
pinions may be so arranged as to cause the 
carriage to be advanced or retrograded 
through a space equal to the width of the 
land operated upon, and completed by the 
plough, x’oller, harrow, or other implement, 
during the time occupied in the passage of 
such implement between the principal and 
auxiliary carriages. Or the principal car- 
riage may rest, during the time of perform- 
ing such operations, and be put in motion at 
required intervals, by thi’owing the pinion 
g, on the crank shaft/*, into and out of 
gear, with suitable trains of wheels. 
The auxiliary carriages must be advanced 
or retrograded at rates corresponding with 
the progress of the principal carriage, whe- 
ther the latter be moved continuously or at 
intervals : this may be effected through the 
pinion u, shown in the plan or horizontal 
view, fig. 6, which pinion takes into the 
teeth of a wheel v, on the axle bearing the 
broad rollers or drums w, to; and, by turn- 
ing the axle of the pinion by a hand spike 
a?, the carriage will be moved. 
Another obvious mode of communicating 
motion, and one capable of giving various 
speeds to the auxiliary carriage, is the em- 
ployment of a train of wheels and pinions, 
actuated by winches, gearing into the spur 
wheel on the shafts, bearing the two drums 
or rollers. The auxiliary carriages must 
be sufficiently heavy to resist the drag or 
force exerted upon the cord, when the 
plough or other implement is drawn from 
the principal carriage towards it. In cases 
when a very great power may require to be 
exerted, the auxiliary carriage must be 
weighted accordingly ; or it may occasion- , 
ally be made fast to stakes fixed at proper 
distances in the soil by a cord or chain, so 
as to oppose the greatest resistance to the 
pull of the track rope : in other cases, 
where operations may have to be performed 
at considerable intervals or distances, the 
one from the other, and draining ploughs or 
other implements requiring great force may , 
have to be used, the pulley, round which 
the cord passes from the principal carriage, 
may be attached to stakes or posts driven 
in the soil at proper distances, or a porta- 
ble crane may be employed for this pur- 
pose. 
I do not claim as any part of my inven- 
tion, the particular construction of the steam- 
engine delineated. I have adopted it, as 
well suited for impelling the carriage, and 
for accomplishing the various objects of my 
invention ; but other forms of engines, as 
well as other agents than steam, may be 
applicable as a motive force. 
Upon mosses or bog lands, where coal or 
other fuel may be too expensive, or too dif- 
ficult to obtain, I propose to use peat to 
work the engine ; in which case, it v/ill be 
necessary to make the furnace or fire-box of 
the boiler sufficiently capacious, for con- 
taining such a quantity of this bulky kind of 
fuel as will produce t’ne requisite abundance 
and foi’ce of steam ; and as, in such situa- 
tion, water is at most times procurable from 
the drains, I propose to supply t’ne boiler 
either directly from the drains, or from 
holes formed at convenient distaxices, by 
attaching a hose to the pipe of the pump. 
I do not intend to confine myself to the 
precise material or construction, arrange- 
ment or dimensions, of the parts of the
