I, FERDINAND KRAUS of Neuss on the Rhine Germany, 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 machine will pack powdered materials, cement, ceruse and such like into
barrels or other bins and sacks. The powder is fed in by a rotatory worm and
pressed into the barrel by several spiral shovel-formed propellers, whilst the raised
platform bearing the barrel recedes under the growing pressure of a counter-
weight by which it is balanced. At the same time the noxious dust is taken
out by aspiration and blown into a dust-collector.
The operation of the packer:-The farinaceous and granulated material is fed
from a bin into the cylinder a and brought down by means of the worm 6 to the
shovel-formed spiral propeller c, which is driven throughout the shaft of the
worin by the gearing d with a velocity independent of the velocity of the worm b
driven by the gearing e.
The platform bearing the barrel ƒ is vertically movable between the rails
and will be held down in the lowest position by the lever i and the shover k with
the bolts t.
The movable platform is joined with chains to two segments of chain wheels
furnished with the counter-weights n, which elevate the platform with the empty
barrel-Fig. 2-to the bottom of the sheet-iron cylinder o including the propeller
shovels.
The friction brake p and g slightly pressed balances the over weight of the
counter-weights. In this position of the platform the counter-weight n has its
lowest situation and therefore the least effect.
The worm and the propellers thrown in gear the flour is pressed into the barrel,
the platform recedes and the lever m with the counter-weight rises. The growing
effect of the counter-weights moving in a circle balances the platform and the
barrel filled more and more, regulates the pressure and packs a uniform tightness
from first to last.
On reaching the floor the platform rests upon the bolts t, the worm and the
spiral propellers are thrown out of gear. The shover k is moved and removed,
the platform is clinched and the machine ready for another barrel.
In order to collect the raised dust the cylinder o is surrounded by a case v of
dense cloth, from which the dust is taken out by aspiration.

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.) Machine for packing powdered materials, with two different means for
feeding and packing in such a manner, that the flour is fed in by the rotation of
a worm b and pressed and packed by spiral shovel-formed propellers with a special
gear and independent velocity.

page_text: (2.) The above named machine with counter-weights n oscillating in a circle
in order to balance the growing weight of the barrel by the augmenting pressure
as they rise from the vertical to the horizontal position.
