Invention of "AN IMPROVED GRAIN-SORTING AND SIFTING-MACHINE."
PROVISIONAL SPECIFICATION left by the said Carl Pellenz at the Office
of the Commissioners of Patents on the 25th June 1879.
CARL PELLENZ, of Manderscheid, Rhenish Prussia. "AN IMPROVED GRAIN-
SORTING AND SIFTING-MACHINE."
My said Invention relates to an improved grain-sorting and sifting-machine, by
means of which I effect a superior cleaning of the grain, which, having passed the
machine, is ready for sale or use, and I further obtain a considerable saving of space
in comparison with all other machines of the same kind, and my improved machine
is of considerably less weight, and requires less driving power than any other.
The wheat, barley, or grain to be cleaned is poured into a funnel, the lower
opening of which is closed by an adjustable rocking-slide by the oscillating move-
ments of which the grain is allowed to pass, and while passing, it is equally spread
upon a rocking-sieve arranged below the said funnel, through which sieve the grain
along with the weeds (that is to say, the seeds of wild flowers or plants) is allowed
to pass, while all other objects greater in size than the grain, such as straw, ears,
stones, and the like, aro retained.
From the said sieve the grain, weeds, and the like fall upon a woollen cloth or
a fabric with fibrous surface, revolving upon a pair of rollers, and taking away all
weeds with fibrous and edged surface. The grain and smooth weeds roll down the
said cloth or fabric, and fall into a funnel, from which they pass into a revolving
cylinder, the circumference of which is perforated with oblong slots, of the same or
similar kind as those in the said rocking-sieve. The said slotted cylinder is
arranged in an inclined position, and the grain accordingly falls out at the lower
end. The said slotted cylinder revolves within another cylinder of a larger diameter,
keyed upon the same shaft with the inner cylinder. The said shaft forms a knee,
and the slotted cylinder being keyed on one end of the said shaft, the other or outer
cylinder on the other end, both these cylinders have an inclined position in an
opposite direction. The inner surface of the said outer cylinder is provided with.

page_text: semi-circular, or nearly semi-circular depressions as usual in sorting-machines. In
the said depressions, the round weeds among the grain are retained' and thrown
out during the rotation into a rocking-trough arranged between the slotted inner
cylinder and the outer sorting-cylinder. The said trough is attached by an arm to
a sleeve upon the shaft, common to the two cylinders, and receives a rocking
motion by suitable means.
The weeds from both said cylinders are thrown into the said rocking-trough,
whence they run out of the machine, the said rocking trough having an inclined
position.
The said inner or slotted cylinder may casily be taken out of the machine and
exchanged for another, to provido for different kinds of grains which may require
other slots.
Movement is imparted to the said machine by a winch-handle or driving-pulley
upon a shaft with strap-pulleys, the straps passing around the said two cylinders,
and straps also drive the shafts of the fibrous-cloth-rollers, as also the shaft which
operates the rocking-movement of the rocking-sieve and the rocking-slidé above
described.
My said machine may also be provided with a ventilator if required.
SPECIFICATION in pursuance, of the conditions of the Letters Patent filed by the
said Carl Pellenz in the Great Seal Patent Office on the 24th December 1879.
CARL PELLENZ, of Manderscheid, Rhenish Prussia. "AN IMPROVED GRAIN-
SORTING AND SIFTING MACHINE."
My said Invention relates to an improved grain-sorting and sifting machine, by
means of which I effect a superior cleaning of the grain, which having passed
through the machine; is ready for sale or use; and I further obtain a considerable
saving of space in comparison with all other machines of the same kind, and my
improved machine is of considerably less weight, and requires less driving power
than any other..
In the accompanying Drawings, Fig. 1 is a longitudinal section of my said
improved machine; Fig. 2 is a vertical section of the same.
The wheat, barley, or other grain to be cleaned is poured into the funnel A, the
lower opening of which is closed by an adjustable rocking-slide d, by the oscillating
up and down movement of which the grain is allowed to pass, and while passing,
it is equally and circnlarly spread upon the rocking-sieve b arranged below the said
funnel A. The said sieve b is provided with oblong slots, as shewn in Fig. 3, of a
suitable size; through which slots the grain along with the weeds, that is to say, the
seeds of wild Bowers or plants, is allowed to pass, while all other objects greater in
size, such as straw, ears, stones, and the like, are retained. The said sieve b may be
exchanged for another with slots of a different shape or size, as the quality or kind

page_text: of grain may require. The slide d is adjustable by a thumb and counter-nute e',
so as to allow a convenient portion of grain to pass at a time.
с
The rocking-slide d and the rocking sieve 6 are mounted upon the same vertical
shaft c.
The said shaft c receives a rocking movement in the vertical direction by
means of a ratchet wheel R mounted upon a horizontal shaft. A spiral spring
provided in the cylinder 8 resists to the said rocking movement, and pushes the
shaft c down after every lift. The ratchet wheel R having seven cogs, the shaft o
with the slide d and sieve b will be seven times lifted during one revolution of the
Baid wheel R, and by these means the grain is violently shaken upon the sieve b
through which it falls upon the woollen cloth or fabric B with fibrous surface. The
said cloth B revolves upon a pair of rollers C, D, which are adjustable in their
position, and by its fibrous surface, the said cloth takes away all weeds with fibrous
and edgy surface, which weeds are thrown out of the machine near B'. The grain
and smooth weeds roll down the said cloth or fabric B, and thence fall into a funnel
E, from which they pass into a revolving cylinder F, the circumference of which is
perforated with oblong slots of the same or similar kind as those in the said
rocking-sieve b, and as shewn in Fig. 3. In the said cylinder F the grain is
cleaned of all oblong seeds which fall through the slots into a rocking-trough K, as
hereinafter described. The said slotted cylinder F is arranged in an inclined position
and the grain accordingly arrives and falls out at the lower end g through suitable
channels into another cylinder H of a larger diameter, within which the said
cylinder F revolves. The two cylinders F and H revolve upon the same shaft h,
which is secured in the frame by the nuts T, T¹. The said shaft h forms a knee,
and the slotted cylinder F being mounted on one end of the said shaft, the other or
outer cylinder H on the other end; both these cylinders have an inclined position
in an opposite direction. The front or lower end of the outer cylinder H is sup-
ported by a bearing L which may be provided with little rollers to reduce the
friction. The inner surface of the said outer cylinder H is provided with semi-
circular or nearly semi-circular depressions, as usual in grain-sorting machines. In
the said depressions the round weeds among the grain, and also the broken grains
are retained and thrown out during the rotation at x, into the rocking-trough K
arranged between the two cylinders F and H. The said trough K is attached by
an arm to a sleeve ¹, mounted loosely upon the shaft h. The said sleeve i¹ is in
rocking-gear with another sleeve i, which revolves upon the shaft h in connection
with the cylinder F. The sleeve is backed by a spiral-spring k which keeps the
same in gear with the sleeve i. By means of this rocking-gear of the revolving
sleeve i and the elastic sleeve i¹, the trough K receives an oscillating movement,
and the said trough having besides an inclined position, all the weeds collected in
it from the two cylinders F and H are thrown out at g. The good clean grain
comes forth from the inclined cylinder H at f, where it leaves the machine in a
state ready for sale or use.
The said inner or slotted cylinder F may be easily taken out of the machine by
unscrewing the nut T, the funnel E, and the collar r. It may be replaced then by
another cylinder of differently shaped slots, to provide for a different kind of
grain.
Movement is imparted to the said machine by a winch handle a or driving-
pulley upon a shaft upon which the strap pulleys n, o, u, are mounted. The
driving strap first passes around the cylinder F, then upon the pulley m, thence
upon the pulley n, from which it passes down around the cylinder H to the other
side, around the pulleys o and p, and then again around the cylinder F. The shaft
of the ratchet-wheel R receives motion by the pulleys u and v. The pulleys o and
p are loose upon their shafts, and revolve in the opposite direction of their respective
shaft..
In this improved machine the grain is subsequently cleaned, first from stones,
ears, straw, etc., by the rocking-sieve b, then from weeds of fibrous and edgy surface
by the fibrous cloth B, then from oblong weeds by the slotted cylinder F, and
finally from round weeds and broken grains by the sorting-cylinder H.

page_text: A modification of the construction of part of this machine is shown in a reduced
scale in Fig. 4 and 5.
The funnel A is closed below by an adjustable slide d arranged outside the
funnel, and operated as required by a handle. Below the funnel A a rocking-
trough dis arranged into which the grain passes at a rate adjusted by the slide d.
The said trough d¹ receives an oscillating movement by means of a ratchet-wheel
R, the shaft of which is worked by a winch-handle. At every stroko a certain
quantity of grain is thrown from the rocking-trough d' upon the hind-end of the
rocking sieve b, which hind end turns upon a stationary shaft s, while the front end
of the said sieve b is moved up and down by the ratchet-wheel R. By means of
this rocking or oscillating movement, the grain passes from the hind-end of the
sieve towards the front-end. During the passage, the good grain and the small
weeds fall through the said sieve b, and are carried by a channel to the sieve-
cylinder F, while the stones, straw, cars, and coarse matters fall from the front of
the sieve b upon the channel w, by which they are carried out of the machine.
This construction allows a better arrangement of a ventilator, as indicated in
Fig. 4. The fibrous cloth B inay be left away, if convenient, in this construction.
Having thus fully described my said Invention, what I claim is,-
First. The combination of the vertical shaft c with the rocking-slide d, and the
rocking-sieve b worked by the ratchet wheel R.
Second. The combination of the two cylinders F and H working one in another
in an inclined position opposite to each other, and revolving upon the same shaft h.
Third. The arrangement of the rocking-trough K between the two cylinders F
and H, and the mechanism of imparting the oscillating movement to the said
trough, consisting of the sleeves i, i, in gear, and in combination with a spiral
spring k.
Fourth. The arrangement of the rocking-trough d' in combination with the
rocking-sieve b, as shewn in Fig. 4 and 5.
All substantially as described and for the purpose set forth.
In witness whereof, I have hereunto set my hand and affixed my seal, this
Eighteenth day of December 1879.
