PROVISIONAL SPECIFICATION.
A New or Improved Machine for Sowing Turnip, Carrot, Mangold,
and such like Seeds.
I, WILLIAM DOYLE of Selskar Iron Works, Wexford, Ireland, Agricultural
Machine Maker, do hereby declare the nature of this invention to be as follows:-
This invention has reference to a new or improved machine whereby agricultural
seeds such as turnip, carrot, mangold and such like may be sown with the
greatest regularity whether up or down hill, and whereby the quantity of seed to be
sown over a given area may readily be controlled and also whereby the flow of seed
may be stopped when the machine is turning on the headland thus preventing
waste.
In carrying out my invention I construct the framework and seed box in one
casting.
On the free ends of the spindle which carries the grooved, or ridge roller, I mount
suitable eccentrics which operate by means of connecting rods and cranks, an
elevating wheel arranged in the seed box.
This wheel is provided with, suitable vanes and brushes and when rotating
elevates the seed placed in the box and delivers through a suitable pipe into a
coulter arranged underneath from which it falls to the ground.
Thus as the machine travels the rotation of the ridge roller is communicated.to
the wheel and the seed distributed as required..
For the purpose of regulating the quantity of seed delivered over a given area,
or for stopping the flow of seed altogether (as when turning round the headland) a
longitudinal graduated lever is suitably fulcrumed on the framework which operates
a brass sliding plate pierced with holes of different sizes according to the class of
seed to be sown.
The machine is provided with a hind roller for steadying its motion which is
formed of cast iron in two parts suitably rivited together.
Dated this 13th day of April 1896.

COMPLETE SPECIFICATION.
A New or Improved Machine for Sowing Turnip, Carrot, Mangold,
and such like Seeds.
I, WILLIAM DOYLE of Selskar Iron Works, Wexford, Ireland, Agricultural
Machine Maker, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention has reference to a new or improved machine whereby agricultural
seeds, such as turnip, carrot, mangold and such like may be sown with the greatest

page_text: regularity whether up or down hill, and whereby the quantity of seed to be sown
over a given area may readily be controlled and also whereby the flow of seed may
be stopped when the machine is turning on the headland thus preventing waste.
In carrying out my invention I construct the framework and seed box in one
casting.
On the free ends of the spindle which carries the grooved, or ridge roller,
I mount suitable eccentrics which operate by means of connecting rods or cranks,
an elevating wheel arranged in the seed box.
This wheel is provided with suitable vanes and brushes and when rotating elevates
the seed and delivers through a suitable pipe into a coulter arranged underneath,
from which it falls to the ground.
Thus as the machine travels, the rotation of the ridge roller is communicated to
the wheel, and the seed distributed as required.
For the purpose of regulating the quantity of seed delivered over a given area,
or for stopping the flow of seed altogether (as when turning round the headlead),
a longitudinal graduated lever is suitably fulcrumed on the framework which
operates a brass sliding plate pierced with holes of different sizes according to the
class of seed to be sown, or the quantity to be sown in any given area.
The machine is provided with a hind roller for steadying its motion, which may
be formed of cast iron in two parts and suitably riveted together.
In order that my said invention may be more readily understood I will describe
the accompanying drawings.
Fig. 1 represents the plan of a seed sower constructed according to my.
invention.
Fig. 2 is a cross section of the seed box, showing the brass sliding plate across its
outlet; and
Fig. 3 is a plan of the sliding plate (enlarged).
Since filing my Provisional Specification I have discovered that some of the
features therein described are not new, and I therefore disclaim same, restricting
my invention to the feature which I now proceed to describe, namely, the
arrangement for regulating the supply of seed, and cutting it off when required.
This arrangement consists of a longitudinal lever a, fulcrumed at b, and connected
by a hinged joint to the sliding plate c (Fig. 3), which slides horizontally across the
outlet of the seed box, and is pierced by several holes of different areas according
to the quantity of seed required to be deposited over a given area.
The free end of the lever works in a horizontal groove d, which is graduated and
numbered so that the lever handle may be fixed at any number.
These numbers are so arranged in relation to the apertures in the sliding plate,
as to indicate the number of pounds of seed deposited per acre.
Thus when the lever handle is fixed at say, number 3, the quantity of seed
discharged from the seed box will equal three pounds per acre and so on,-the
element of speed of course being considered a constant factor.
When the lever handle is in its normal position, the outlet of the seed box will
be closed altogether.
Thus my invention affords a ready method of controlling the quantity of seed
sown, which may be operated without stopping the machine and which will
indicate practically at any moment the quantity being deposited per acre.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First In machines for sowing turnip, carrot, mangold, and such like seeds, the
use and application of a lever a for controlling and indicating the quantity of seed
sown over a given area, substantially as herein described.
Second: In machines for sowing turnip, carrot, mangold and such like seeds, a
lever operating a sliding plate pierced with holes of different areas, for the purpose
and in the manner substantially as herein specified.

page_text: Third: The use and application of a lever working in a horizontal graduated
alot and operating in a horizontal sliding plate, in combination with machines
for sowing turnip, carrot, mangold and such like seeds, in the manner substan-
tially as herein specified and set forth.
Dated this 12th day of January 1897.
