"
IMPROVEMENTS IN MACHINERY FOR PELING
BARLEY WITH SELF-ACTING FEEDER AND TURNING BARREL." A communication
from Moritz Martin, residing at Bitterfeld, Prussia.
It is a known fact that of all existing peeling mills for barley the Dutch mill
with vertical stone is the best, both with regard to its working ability, and to the
good quality of the manufactured article.
Many attempts have been made to secure to the Dutch mill self-acting feeders,
or feeders working continually, but the results have not been satisfactory as yet,
because the manufacturers were compelled to fix the barrel in an immoveable
position (not turning), whereby the barley is exposed to an irregular action. To
meet these inconveniences and to render the Dutch mill with vertical stone a
machine that will give satisfaction in every respect, I have improved the Dutch
mill by several devices, which I shall hereafter describe with reference to the
accompanying Drawings.
The barrel A of my improved apparatus is provided with a toothed crown B
gearing into a pinion on a small shaft C (Fig. I.), which receives its motion from
the main shaft D by means of the pulleys E, E, and a belt, the smaller pulley being
keyed to the main shaft carrying the stone F and pulley G, which latter is in direct
communication with the shafting. The barrel A is supported on the stands H, H,
which carry the bearings of the main shaft. The revolutions of the stone transferred
to it by the pulley G amount to 240-260 per minute, while the barrel moving in
an opposite direction only makes 4-8, which can be regulated by the size of the
pulleys E, E. The feeding or filling in of the barley from the vessel I and funnel a
through the enlarged neck K of the barrel is effected by cylinders L. L, slotted over
their whole length, which allow the barley to fall through when the slot stands

vertical (as the upper cylinder in Fig. I. of the Drawing), and shut the opening like
a kind of cock by bringing the slot in a horizontal position. The same may be said
of the cylinders M, which allow the grist to pass from the revolving barrel into the
surrounding casing N formed of two wooden rings lined with sheets of zinc, which
are fitted tightly by means of felt against the conus turned on the edges of the
barrel (Fig. IV.).
The motion of the cylinders for feeding and emptying is derived from disks by
means of a peculiar mechanism represented especially by Fig. III., IV., V., VI., VII.
The disks or curve plates d, d, receive their motion from two worms b, b, (Fig. I.
and II.), gearing into wheels with screw-shaped toothing c, c, fixed to the shafts
carrying the said curve plates d, d, (Fig. III.-VIII.). One of these worms is
fastened on the neck K of the barrel turning with it, while the other is in firm
connection with the stand H, and imparts motion to the wheel c, when the latter
glides slowly with the whole mechanism of the curve plates round the circumference
of the worm b. The curve plates are composed of two halves, and provided with
slots e and teeth f. By this arrangement I have succeeded in regulating perfectly at
will the time of opening or shutting of the slotted cylinders, simply by placing the
plates with slots and teeth in a corresponding position opposite one another, which
position can easily be changed by loosening the nut g, Fig. III. and IV. The pins h,
Fig. VII. serve to secure the position of the regulated plates, and a scale on the
outer circumference shows the respective position at any time; Fig. VI. and VII.
show respectively the lower and upper part of the curve plates; Fig. V. represents
the circuinference of the curve plates unwound, with the slots and teeth turning the
disks of the cylinders ; Fig. VIII. is a section of one cylinder.
The curve plates of the filling and emptying mechanism on the left side of Fig. I.,
guide above a cylinder of the described kind, but below a turning plate 7. This
plate (Fig. 2) is arranged in such a way that the grist falling out of the casing
surrounding the barrel through opening m is thrown out, either to the left side or
to the right, in accordance with the position of plate l. Now the position and
change of position is always so regulated that the bran escaping continually through
the lattice of the barrel falls out on one side, while the plate 7 shifts over to the
other side, as soon as one of the cylinders M has taken its lowest position and
opens, allowing the ready ground barley to fall out.
It is obvious that by this arrangement the article obtained is a much cleaner one
than could be got in the ordinary mills.
Having thus fully described my said Invention, and the manner of peforming the
same, I wish it understood that I claim as my Invention,-
1. The disposition of the revolving barrel A shut off tightly from the exterior by
wooden rings and felt, as herein-before described and represented in connection
with..
2. The emptying mechanism turning with the barrel, and composed of. slotted
cylinders M moved by adjustable curve plates d, d, by means of a screw gearing and
worms b, b, on the main shaft D, as specified.
3. The filling and emptying mechanism moving the feeding cylinders L, L, and
the plate in the same way by curve plates, the plate 7 especially, so as to separate
the greatest part of the dirt and bran from the grist, thereby giving an article
of the best quality.
In witness whereof, I, the said Carl Pieper, have hereunto set my hand and
seal, this Twentieth day of November, in the year of our Lord One thousand
