Year: 1856

page_text: LETTERS PATENT to Thomas Chambers, junior, of Colkirk, Fakenham,
in the County of Norfolk, for the Invention of "IMPROVEMENTS IN
AGRICULTURAL DRILLS.".
Sealed the 25th November 1856, and dated the 6th June 1856.
PROVISIONAL SPECIFICATION left by the said Thomas Chambers at the
Office of the Commissioners of Patents, with his Petition, on the 6th
June 1856.
I, THOMAS CHAMBERS, junior, of Colkirk, Fakenham, in the County of
Norfolk, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
AGRICULTURAL DRILLS," to be as follows:-
This Invention has for its object improvements in agricultural drills, with
a view to deposit at intervals in place of continuously, and the same is appli-
cable when drilling seeds and liquid manure, and also when drilling seeds,
water, and manure. For these purposes there is applied a rotating hollow
wheel or chamber to each channel or furrow made by the drill. The rotating
hollow wheel or chamber has spouts or passages at intervals at its periphery.
The seed and liquid. manure or the seed, water, and manure are delivered
into the interior of the rotating wheel or chamber from the separate compart-
ments of the drill containing them, and they are retained from flowing out
from the wheel or chambers, except when, by the rotation of the hollow wheel
or chamber, a spout or outlet comes to the ground. The axis of the rotating
wheels or chambers may receive motion by wheels thereon, which run on the
land, and the running wheels may be made to expand and contract, to vary
the distance at which the deposit takes place from the spouts or outlets, or
the axis may receive motion by gearing from the drill.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
CHAMBERS, junior, of Colkirk, Fakenham, in the County of Norfolk, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of June, in the year of our Lord One
thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did, for Herself, Ier heirs and successors, give and grant unto me, the said
Thomas Chambers, Her special licence that I, the said Thomas Chambers, my
executors, administrators, and assigns, or such others as I, the said Thomas
Chambers, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN AGRICULTURAL
DRILLS," upon the condition (amongst others) that I, the said Thomas
Chambers, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Thomas Chambers, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in agricultural drills, with
a view to deposit at intervals in place of continuously, and the same is appli-
cable when drilling seeds and liquid manure, and also when drilling seeds,
water, and manure. For these purposes there is applied a rotating hollow
wheel or chamber to each channel or furrow made by the drill. The rotating
hollow wheel or chamber has spouts or passages at intervals at its periphery.
The seed and liquid manure, or the seed, water, and manure, are dilivered into
the interior of the rotating wheel or chamber from the separate compart-
ments of the drill containing them, and they are retained from flowing out
from the wheel or chamber, except when, by the rotation of the hollow wheel

page_text: or chamber, a spout or outlet comes to the ground. The axis of the rotating
wheels or chambers may receive motion by wheels thereon, which run on the
land, and the running wheels may be made to expand and contract, to vary
the distance at which the deposit takes place from the spouts or outlets, or the
axis may receive motion by gearing from the drill.
And in order that the said Invention may be most fully understood, and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is a side view, and Figure 2 a plan, of an apparatus constructed
according to my Invention for drilling or depositing at intervals seeds and
liquid manure, or other substance. A is a frame, which is attached to a liquid
manure or water drill in the place of the common lever and coulter. The
frame A carries a shoot or conducter B, into which the seed and liquid
manure or other matter is delivered in the usual way; C is a hollow wheel
or chamber mounted on an axis carried in bearings by the frame A. Into
the hollow wheel C the matters to be deposited are discharged by the shoot B;
c, c, are spouts formed on the periphery of the hollow wheel C, and through
these spouts the matters delivered by the shoot B are deposited at intervals in
the groove or furrow made by the coulter D; E is a wheel mounted on the
same axis as the hollow wheel C. The periphery of the wheel E is divided
into four or more parts or sections, each of which is attached to one of the
spokes of the wheel, and these spokes are constructed as is shewn by the
Drawing, so that they may be lengthened or shortened, as may be required, to
regulate the distances apart at which the patches or seed, manure, or other
substance are deposited.
In witness whereof, I, the said Thomas Chambers, have hereunto set my
hand and seal, this Second day of December, in the year of our Lord
One thousand eight hundred and fifty-six.
Witness,
WILLIAM CHAMBERS.
