Fig. 1 cousists of a brass plate or frame. wherein the brass roller A is fixed
with two caps and screws at B, B. The brass roller hath three, four, or more

page_text: sets of holes, consisting of different numbers, (viz,) from six to eighteen in
each set or circumference. Fig. 2 is a sliding cover, whose inside closely fits
the roller A. The opening B, moved over any of the different numbers of
holes, and screwed fast by the two screws A, A, in one revolution will discharge
different number of seeds. The row of holes with six in it will sow the seed at
sixteen inches distance from each other, and the row with eighteen holes in it
will sow the seed five inches distance from each other; but the holes may be
varied in their numbers, agreeable to a purchaser. At C is a brass screw
hollowed at the lower end, and cemented, full of horse-tail hair, and of the
diameter of the aperture B, in the center of Fig. 2. Fig. 3 is a section of
Fig. 2, with the seed box upon it. Fig. 4: A is a sliding bar of wood, two feet
long, two inches broad, and one inch and a half thick; B is a cast-iron or
wood wheel, thirty-one inches diameter, and fastened by a square hole and nut
upon the end of the iron axletree C, which axletree runs, and is fixed to the
sliding bar A by the two collars at D, D. The axletree hath a square hole in
the end at E, where it receives the square end of the arbor E, in Fig. 1.
F, F, F, is the side view of the seed box spout, and fixing to the end of the
sliding box by means of the cock E, part of the plate or frame, as at D, in
Fig. 1, and screwed so as to be in a direct line with the axcltree of the wheel
B. G is a sliding cap or box, through which the sliding bar A moves back-
wards and forwards from D to D, and may be fixed in any part between to
suit the breadth of the furrow intended to be ploughed; through the upper
part of the same the wood frame B, Fig. 6, slides likewise to and fro, and may
be fixed by the same screw II, Fig. 4, by which motion the seed may be
dropped either under the furrow or upon the surface of the ground.
Fig. 6:
A, the stud to go through the plow beam, as near the coulter hole as con-
venient, on the left-hand side of the beam; the frame B, two feet six inches
in length and three inches square, which frames slide through the box or cap,
as at I, in Fig. 4. At E the wheels, axletree, and the arbor of the drill roller
join, and couple by means of a male and female square, or an universal joint.
Fig. 7 A, the stud, as at A, Fig. 6, to put through the plow beam as near the
coulter hole as convenient, on the right-hand side; the same, frame B, Fig. 6;
the same, drill F and wheel B, as described in Fig. 4. Figs. 8, 8, is a frame
with two arms and two bolts, as at A, A; the upper part of the wheel's axletree
goes through the arm and frame at B, and rises and falls to suit the depth you
plow, secured by the screw C, and in some measure answers the purpose of a
single-wheel plow, the same wheel and the same drill, as described above.
Upon each centre a contrate wheel is fixed, of equal sizes, and á rolling shaft D
with a nut upon each end to suit each wheel; and by varying the numbers of

page_text: the nuts upon the shafts you vary the quantity of seed to be sown. This drill
may be used advantageously in sowing of rape and other small round seeds.
In witness whereof, I, the said William Jackson, have hereunto set my
hand and seal, this Eighteenth day of November, in the year of our
Lord One thousand eight hundred and one.
