Improvements in Agricultural Drills for Sowing Seeds and other
like purposes.
I, ALFRED CHENHALLS, the younger, of 1 Market Street, St. Just, in the
County of Cornwall, Registrar for Births, Deaths and Marriages, do hereby declare
the nature of this invention to be as follows :-
This invention relates to the manner in which I construct and arrange seed drills
for ensuring a uniform distribution of the seed and at the same time to prevent
waste and imperfect sowing.
In carrying my invention into effect I construct a hopper of any desired shape
for retaining the seed which is to be sown, and I provide at the lower or underside
of the hopper a trough or funnel for delivering the seed on to my improved
distributor. This distributor I form of metal or other suitable material as a wheel
or disc having a circular periphery around which I cut or arrange a number
of holes, pits or pockets to receive and retain the seed as it falls from the hopper
trough or funnel. The seed pits or holes within the circumference of the
distributing roller I cause to be formed in such positions and intervals desirable for
any particular speed of distribution, or to give any required distance apart of the
seeds in the soil. To effectually retain the seed in the pits after each pit has
passed the hopper funnel I arrange a guard or band around one portion of the
circumference of the distributing or dropping wheel in such a manner that the seed
is enclosed or retained within the pits by the circular plate running from the hopper
funnel to the underside of the disc or wheel, at which lower position alone the seed
is able to fall out on to the soil.
I arrange my distributing wheel or dropper to be driven by means of any
central shaft connected by ordinary gearing or chains to any main moving axle or
spindle of the machine.
I mount any desired number of such rollers and guards upon any one frame
connected to separate hoppers or to a large main hopper feeding on to each
roller by means of the funnel placed over the same; and I form one large guard to
enclose all the rollers, or have separate and independent guards or retainers placed
round each distributor.
I construct a complete drill suitable for hand wheeling or to be drawn by animal
power in the usual well known manner, modifying the hopper and the driving gear
to suit my improved distributors and arranging the guards as herein before described
for retaining the seeds while the distributing rollers are in motion. Instead of
constructing separate rollers for a wide machine I sometimes arrange one long
roller having a number of holes or pits provided upon it to suit any particular
requirement.

Improvements in Agricultural Drills for Sowing Seeds and other
like purposes.
I, ALFRED CHENHALLS, the younger, of 1 Market Street, St. Just, in the
County of Cornwall, Registrar for Births, Deaths and Marriages, 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 relates to the manner in which I construct and arrange seed drills
for ensuring a uniform distribution of the seed and at the same time to prevent
waste and imperfect sowing.
Referring to the accompanying sheet of explanatory drawings :-
Figures 12 and 3 are side, back, and sectional side elevations respectively
of a seed drill constructed and arranged in accordance with my present invention,
while Figure 4 shows such a seed drill mounted upon wheels and provided with
handles for hand wheeling.
In carrying my invention into effect as illustrated in the figures of the accom-
panying drawings, I construct a hopper A of any desired shape for retaining the
seed which is to be sown, and I provide at the lower or underside of the hopper a
trough or funnel for delivering the seed on to my improved distributor. This
distributor I form of metal or other suitable material as a wheel or disc B having a
circular periphery around which I cut or arrange a number of holes, pits or
pockets to receive and retain the seed as it falls from the hopper trough or
funnel A. The seed pits or holes b within the circumference of the distributing
wheel roller B I cause to be formed in such positions and intervals desirable for any
particular speed of distribution, or to give any required distance apart of the seeds
in the soil. To effectually retain the seed in the pits after each pit has passed the
hopper funnel I arrange a guard or band a around one portion of the circumference
of the distributing or dropping wheel B in such manner that the seed is enclosed or
retained within the pits 6 by such circular guard or plate running from the hopper
funnel to the underside of the disc or wheel, at which lower position alone the seed
is able to fall out on to the soil.
I arrange my distributing wheel or dropper B to be driven by means of any
central shaft such as C carried by the frame F and connected by ordinary
gearing or chains D¹ to any main rotating axle or spindle D of the machine on to
which the wheels are mounted and which is driven by the rotation of the wheels
carrying the frame F.
I mount any desired number of such rollers and guards upon any one frame
connected to separate hoppers or to a large main hopper feeding on to each roller
by means of the funnel placed over the same; and I form one large guard to
enclose all the rollers, or have separate and independent guards or retainers placed
round each distributor.
I sometimes mount upon the frame carrying the seed hopper or hoppers, in front
and about the revolving disc, a furrower or furrowers such as E (Figures 1 and 3)
for the purpose of making a furrow or seam for the reception of the seeds, and at
the back of such frame I sometimes similarly mount at G (Figure 4) two or more
harrows in a rake or other form placed at an angle, for covering over or harrowing
the earth over the seeds which have been placed within the seam or furrow.
I construct a complete drill suitable for hand wheeling or to be drawn by
animal power in the usual well known manner, modifying the hopper and the driving
gear to suit my improved distributors and arranging the guards as hereinbefore
described for retaining the seeds while the distributing rollers are in motion.
Instead of constructing separate rollers, for a wide machine I sometimes arrange

page_text: one long roller having a number of holes or pits provided upon it to suit any
particular requirement.
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 :-
1. The combination and arrangement of a seed drill in which one or more hoppers
are employed to deliver the seeds on to a distributing roller, disc or series of discs
substantially as herein before described.
2. The construction of seed drills having a distributing wheel, roller, disc or
series of discs with holes arranged about their periphery, substantially as and for the
purposes hereinbefore described and as illustrated in the accompanying drawings.
3. The construction of a seed drill with distributing hopper and guard
substantially as hereinbefore described and as illustrated in the accompanying
drawings.
