PROVISIONAL SPECIFICATION left by Robert Roger at the Office of
the Commissioners of Patents, with his Petition, on the 23rd June
1856.
I, ROBERT ROGER, of Stockton, in the County of Durham, Engineer and
Ironfounder, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY EMPLOYED IN THE CULTIVATION OF LAND," to be as follows:-
My Invention consists in constructing a travelling windlass, to be actuated
by the endless cord of the Fisken's patent or other system of steam ploughing.
The travelling windlass to have two drums, either on separate axles or on the
same, one to be winding on while the other is winding off the rope. From
the spur wheel attached to such drums, and driving them, I take a power by
pinion and chain wheel; I drive at each end of the said machine a revolving
cultivator in the form of a spiked roller or digging machine wheel, having
spiked teeth on bosses at certain intervals; one set of these is lowered in the
ground and put in motion when the machine is going in one direction, and
when going in the opposite direction this set is raised, and the other lowered
into the ground. The rollers or wheels are driven by means of a flat chain and
chain wheels, or other suitable means. The spiked wheels, travelling at a high
velocity, clear their own way and reduce the land to a fine state of cultivation
for summer tillage. By removing a suitable number of the spiked teeth the
cultivator or wheel will turn up large clods, and expose them to the weather

page_text: for winter or autumn tillage. The high velocity at which the wheels are
driven prevents any clogging up of the teeth. I find that the cultivator requires
to be held back, as its own tendency is to go forward; therefore I employ an
additional break acting on the circumference of the spur wheel of the paying-
off drum. I adapt the fixed windlass system of tillage to my rotary cultivator
by winding on one rope to one drum by means of the paying out of another
while the machine is hauled in the other direction, so as to be in readiness to
drive in, paying out when returning in the opposite direction. From the rotary
motion thus obtained from a simple hauling motion, I drive, by means of a spur
wheel attached to the drums, my rotary cultivator, as in the travelling windlass
system; I also attach to the rotary motion thus obtained a chain of buckets
and knives similar to those used in a dredging machine, and a suitable ladder
and raising and lowering apparatus for cutting drains to any depth, and a
sloping platform to deliver the soil so raised and cut on one or both sides of
the drain.
