PROVISIONAL SPECIFICATION.
An Improved Maize Drum or Cylinder for Thrashing Machines.
We ANIBAL FERRI, Agriculturist and EUGEN BEHLES Merchant, both of
No. 2 Strada Bibescu Voda Bucharest, in the Kingdom of Roumania, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to enable the agriculturist or farmer to dispense
with the expensive plant which hitherto, he has had to provide in addition to the
thrashing machine, for the purpose of removing the grain from the spikes, or ears
of Indian corn or maize.
In order to attain this end, there is according to this invention substituted for
the ordinary cylinder of the thrashing machine, a special cylinder or drum, which
converts such thrashing machine into a maize grain-removing or stripping
machine.
The quantity of maize grain which, under the action of the improved maize
drum, undergoes a double purifying process in the thrashing machine, is at least
equal to that which is yielded by the old maize thrashing apparatus in the same
time, while an additional advantage of the novel arrangement is that it enables
spikes or ears of Indian corn to be stripped of their grains, whether or not they
are still enveloped in their leaves or "spathes."
The casing of the drum is provided with longitudinal grooves presenting, each,
(for example) one steeply inclined surface or wall and one gradual incline, whereby.
the spikes or cars of maize, received in these grooves, are as, the drum rotates
compressed between the walls of the grooves and the rods of the cylindrical
thrashing cage or concave, the grains being detached as the spikes or ears are thus
acted upon.
The grain thus loosened drops between the rods of the thrashing cage or
concave and is intercepted by a sifting surface or bottom frame of the thrashing
machine, while the "spadices" or stalks freed from their grain, traverse the
thrashing cylinder or concave from end to end.

COMPLETE SPECIFICATION.
An Improved Maize Drum or Cylinder for Thrashing Machines.
We, ANIBAL FERRI, Agriculturist, and EUGEN BEHLES, Merchant, both of
No. 2 Strada Bibescu Voda, Bucharest, in the Kingdom of Roumania 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
etatement :-
The object of this invention is to enable the agriculturist or farmer to dispense

page_text: with the expensive plant which hitherto he has had to provide in addition to the
thrashing machine, for the purpose of removing the grain from the spikes, or ears
of Indian corn or maize.
In order to attain this end, there is according to this invention substituted for
the ordinary cylinder of the thrashing machine, a special cylinder or drum, which
converts such thrashing machine into a maize grain-removing or stripping
machine..
The quantity of maize grain which, under the action of the improved maize
drum, undergoes a double purifying process in the thrashing machine, is at
least equal to that which is yielded by the old maize thrashing apparatus in the
same time, while an additional advantage of the novel arrangement is that it
enables spikes or ears of Indian corn to be stripped of their grains, whether or
not they are still enveloped in their leaves or spathes."
The casing of the drum is provided with longitudinal grooves presenting, eách
(for example) one steeply. inclined surface or wall and one gradual incline, whereby
the spikes or ears of maize, received in these grooves, are as the drum rotates
compressed between the walls of the grooves and the rods of the cylindrical
thrashing cage or concave, the grains being detached as the spikes or ears are thus
acted upon.
"Th
The grain thus loosened drops between the rols of the thrashing cage or concave
and is intercepted by a sifting surface or bottom frame of the thrashing machine,
while the spikes or ears freed from their grain, traverse the thrashing cylinder or
concave from end to end.
The invention is illustrated in the accompanying drawing in which
Fig. 1 is a cross-section of a part of an ordinary thrashing machine, containing
the drum for removing the grain. from the spikes or ears of Indian corn or
maize, and
•
Fig. 2 is a longitudinal section of the drum only, taken on the line 2-2.in
Fig. 1.
a represents the hopper of the thrashing machine, & is the shaft of the inserted
drum, the casing c of which is connected with the said shaft by means of the
disks f,f, and is the thrashing cage or concave, provided with the rods e. Under
the thrashing cage is arranged a sifting surface or bottom frame g.
The casing c of the drum is provided with longitudinal grooves presenting one
steeply inclined surface or wall and one gradual incline, whereby the spikes or ears
of maize, received in these grooves, are, when the drum is rotated in the direction
of the arrow & in Fig. 1 compressed between the walls of the grooves and the
rods e of the cylindrical thrashing cage d, the grains being detached as the spikes
Dór ears are thus acted upon.
The grain thus loosened drops' between the rods e of the thrashing-cage or
concave d and is intercepted by the sifting surface or bottom frame g arranged
below, while the spikes or ears traverse the thrashing cage d and are delivered
at din emptied state.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
"
A drum for removing the grain from the spikes or ears of Indian corn or maize
to be used in combination with an ordinary thrashing machine, consisting of a
casing provided with longitudinal grooves presenting one steeply inclined surface
and one gradual incline, substantially as berein described.
