Year: 1859

page_text: LETTERS PATENT to Charles Lambert, of Sunk Island, in the County of
York, Farmer, for the Invention of "IMPROVEMENTS IN CORN AND SEED
DRILLS."
Sealed the 15th September 1859, and dated the 18th March 1859.
PROVISIONAL SPECIFICATION left by the said Charles Lambert at tho
Office of the Commissioners of Patents, with his Petition, on the
18th March 1859.
I, CHARLES LAMBERT, of Sunk Island, in the County of York, Farmer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CORN AND SEED DRILLS," to be as follows:-
My Invention consists in fitting a corn and seed drill on the beam of a
plough behind the turnfurrow, and in obtaining motion in the sced hopper by
means of a wheel travelling on the sole or bottom of the furrow. A set of cog
wheels which turn a shaft passing through the seed hopper is set in motion by
the wheel travelling in the furrow. A sliding nut moved by a lever is attached
to one of a set of cog wheels to regulate the delivery of the grain. When not
in use tho drill is raised by means of a lever attached to a cross piece on the
handles of the plough.

by the said Charles Lambert in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
LAMBERT, of Sunk Island, in the County of York, Farmer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of March, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Charles Lambert, Her special licence that I, the
said Charles Lambert, my executors, administrators, and assigns, or such
others as I, the said Charles Lambert, 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 CORN AND SEED DRILLS," upon the condition,
(amongst others), that I, the said Charles Lambert, my executors or adminis-
trators 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 Charles Lambert, do hereby declare
the nature of my 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, reference being had to the Drawings hercunto
annexed, that is to say:→
My Invention consists in fitting a corn and seed drill on the beam of a
plough behind the turnfurrow, and in obtaining motion in the seed hopper by
means of a wheel travelling on the sole or bottom of the furrow. A set of cog
wheels, which turn a shaft passing through the seed hopper, is set in motion by
the wheel travelling in the furrow. A sliding nut, moved by a lever, is
attached to one of a set of cog wheels to regulate the delivery of the grain.
When not in use the drill is raised by means of a lever attached to a cross
pieco on the handles of the plough.
Figure 1 of the accompanying Drawings is a side clevation of a plough,
with a seed drill constructed according to my Invention applied to it; Figure 2

box of wood or iron attached to the plough by bolts, and strengthened by
brackets b, b, one only of which is seen in the Drawing. c is a lever or support,
which is loose at its upper part, and forms a bearing to a spindle e, on which a
cog wheel & is fixed; this spindle passes through the side of the box a and
carries at its inner end a wheel f, to which the ordinary cups for raising seed
are attached. 9 is a spout through which the seed passes from the cups to the
ground; the cog wheel d gears into a similar wheel h, which takes into another
wheel i, in gear with a cog wheel k, on a spindle I, on which is fixed the
wheel m, the rotation of which imparts motion to the wheels of the drill. The
spindle works in a bearing formed in the lower end of the support c, and the
wheels h, i, are also held by the same support; grooves or slots are formed in
the sides of the support for the purpose of altering the position of the wheels; or
wheels of different diameters, or with more or less teeth, may be fixed in order
to vary the speed at which the seed cup wheel frevolves, and consequently the
quantity of seed deposited through the spout g. n is a cord attached at one
end to the lower part of the support c, and at the other to a cross bar between
the handles of the plough, by which the wheel m may be lifted out of the
furrow when the drill is not required to be used; or instead of this cord I
sometimes use a lever, which is attached to the end of the support c at the
same point as the cord, and passing through a loop formed on a cross bar
between the plough handles; or at the side of ono of the handles I some-
times fit to the spout 9 a casting, not shewn in the Drawing, bolted to the plough
and provided with two holes, one to confine the seed in a row, the other to
spread it.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, fitting a corn
and seed drill, constructed and working substantially in manner herein-before
described, on the beam of a plough behind the turnfurrow.
In witness whereof, I, the said Charles Lambert, have hereunto set my
hand and seal, this Sixteenth day of September, One thousand eight
hundred and fifty-nine.
