PROVISIONAL SPECIFICATION.
Improved Mechanism for the Distribution of Powdered or Granular
Materials or Seed-grains, more especially applicable to Agri-
cultural Drills and similar Apparatus.
I, The Rev. ATHANASE FÉLIX JULES ERNEST RABIER, of 40, Rue Raynouard,
Paris, in the Republic of France, do hereby declare the nature of this invention
to be as follows::
My invention relates to improved mechanism for the distribution of powdered
or granular materials or seed-grains, which mechanism is more especially applic-
able to agricultural drills and similar apparatus.
To aid the description, but as an example only, I have shown in the accompany-
ing drawings one method of carrying my said invention into practice.

My apparatus is essentially composed of a hopper a upon the bottom of which a
toothed distributing-bar b is supported; horizontal to-and-fro motion is imparted
to this toothed bar by means of the wheels of the vehicle or in any other con-
venient manner. In the bottom of the hopper longitudinal openings c are
formed, to permit the materials or the grains caught above or below the bar b to
fall outside and to be received, as may be necessary, in a receptacle placed below
the hopper a. The bar bis suitably guided in lateral openings or slots in the
hopper and by a longitudinal cross-piece d fixed in the interior; this cross-piece
also prevents the grains from lodging between the bar b and the side of the hopper.
The ends of the teeth of the bar bare level with the exterior wall of a movable
plate e which, by rising or falling, gives to the longitudinal opening f of the
hopper more or less width, according to the thickness of the bar b and the character
of the seed-plot it is desired to obtain. The movement of the plate e is obtained
by means of the screw g fixed thereon, or in any other suitable manner.

page_text: Any angle may be enclosed between the teeth provided that the sides of the
teeth are of the same length. These angles may vary in size and number and
are further apart or closer together depending upon the nature of the material
or grains to be distributed on the soil, or upon the seed-plots desired.
The teeth of the bar 6 vary with these angles; they are also of greater or less
thickness according to the substances to be sowed.
In the interior of the hopper a stirrer of any suitable construction may be
placed, for example an arm bearing knife-blades or points and having a circular
or horizontal movement in an opposite direction to that of the bar in such a
manner as to assist the entrance of the materials or grains between the teeth of
the said bar and to prevent their clogging. The movement of this stirrer may
be transmitted from any suitable source in any convenient manner..
The operation of my invention is as follows:-
The seed or other material to be sown having been placed in the hopper and
the bar 6 being put in motion, a certain quantity of the grain will lodge between
the teeth of the bar b, which, in its to-and-fro movement, will throw these grains
to right and left broadcast upon the soil in the manner obtained by hand sowing.
To sow in furrows the grains can be caught at one or several places along the
hopper and led to one spot. For this purpose I place in front of each opening of
the hopper an inclined gutter or spout h (Figures 4 and 5) into which the grains
are led by the bar b to be afterwards deposited in the corresponding furrow.
I may, if desired, make the bottom of the hopper horizontal or inclined, so as to
facilitate the exit of the substances or grains to be distributed, and the openings
of the hopper through which the grain falls may be closed by a door or shutter
to prevent the grain falling out when it is required to stop the working of the
apparatus.
I may also alter the shape, size, details and materials employed for the con-
struction of my apparatus, without departing from the nature of my said
invention.

COMIUMIE DIECIFICATION.
Improved Mechanism for the Distribution of Powdered or Granular
Materials or Seed-grains, more especially applicable to Agri-
cultural Drills and similar Apparatus.
I, The Rev. ATHANASE FÉLIX JULES ERNEST RABIER, of 40, Rue Raynouard,
Paris, in the Republic of France, 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: -
My invention relates to improved mechanism for the distribution of powdered
or granular materials or seed-grains, which mechanism is more especially applic-
able to agricultural drills and similar apparatus.
To aid the description, but as an example only, I have shown in the drawings
left with my Provisional Specification, one method of carrying my said invention
into practice.
Figure 1 is an elevation and
Figure 2 a plan of one form of my improved mechanism.
Figure 3 is a rantical trunova

page_text: Figure 4 is a partial elevation showing my improved mechanism for distributing
substances in drills or furrows.

Figure 5 is a transverse vertical section on the line 3-4, Figure 4, and
Figures 6 and 7 show, separately, modifications of the distributing-bars.
Like letters indicate corresponding parts throughout the drawings.
My apparatus comprises a hopper a upon the bottom of which
toothed distributing-bar b is supported; horizontal to-and-fro motion is imparted
to this toothed bar by means of the wheels of the vehicle or in any other con-
venient manner. In the bottom of the hopper a longitudinal openings care
formed, to permit the materials or the grains caught above or below the bar b to
fall outside and to be received, as may be necessary, in a receptacle placed below
the hopper a. The bar b is suitably guided in lateral openings or slots in the
hopper and by a longitudinal cross-piece d fixed in the interior; this longitudinal
cross-piece also prevents the grains from lodging between the bar b and the long
side of the hopper.
The ends of the teeth of the bar bare level with the exterior wall of a movable
plate e which, by rising or falling, makes the longitudinal opening f of the hopper
wider or narrower, according to the thickness of the bar 6 and the character of
the seed-plot, it is desired to obtain. The plate e is moved by means of a screw g,
fixed thereon, or in any other suitable manner.
Any angle may be enclosed between the teeth provided that the sides of the
teeth are of the same length. These angles may vary in size and number and
are further apart or closer together depending upon the nature of the material
or grains to be distributed on the soil, or upon the seed-plots desired.
The teeth of the bar b vary with these angles; they are also of greater or less
thickness according to the substances to be sowed.
In the interior of the hopper, a stirrer of any suitable construction may be
placed, for example, an arm bearing knife-blades and points and having a circular
or horizontal movement in an opposite direction to that of the bar b in such a
manner as to assist the entrance of the materials or grains between the teeth of
the said bar and to prevent them from clogging. The movement of this stirrer may
be transmitted from any suitable source in any convenient manner.
The operation of my apparatus is as follows:
The seed or other material to be sown having been placed in the hopper and
the bar b being put in motion, a certain quantity of the grain will lodge between
the teeth of the bar b, which, in its to-and-fro movement, will throw these grains
to the right and left broadcast upon the soil in the manner obtained by hand sowing.
To sow in furrows, the grains can be caught at one or several places along the
hopper and led to one spot. For this purpose I place in front of each opening of
the hopper an inclined gutter or spout h (Figures 4 and 5) into which the grains
are led by the bar b to be afterwards deposited in the corresponding furrow.
I may, if desired, make the bottom of the hopper horizontal or inclined, so as to
facilitate the exit of the substances or grains to be distributed, and the opening
of the hopper through which the grain falls may be closed by a door or shutter
to prevent the grain falling out when it is required to stop the working of the
apparatus.
I may also alter the shape, size, details and materials employed for the con-
struction of my apparatus, without departing from the nature of my said
invention.
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. The improved mechanism for the distribution of powdered or granular
materials or seed-grains, comprising a toothed distributing bar moved upon the
bottom of a hopper, substantially as herein before described with reference to the
drawings, for the purposes specified.

page_text: Second. The improved apparatus constructed substantially as described with
reference to the drawings, for the purposes specified.
