COMPLETE SPECIFICATION.
A Centrifugal Machine for Incorporating or Mixing Together
Various Substances.
I CARL HERRMANN HAUBOLD, of Chemnitz, Saxony, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:--
My invention relates to the use and construction of centrifugal machines for
incorporating or mixing together various substances to effect the following opera-
tions. Mixing, making emulsions of fats, powders or other substances of any
description with other compounds of a specific gravity superior or inferior to water
such as hydro-carbons, for mixing colours for the manufacture of butter, margarine:
for making emulsions of machine oils for washing and purifying oil vaseline and
other hydro-carbons: for mixing fatty matter with caustic and carbonated lycs: for
mixing chloride of lime with water: for impasting vegetable powders for extracting
purposes for mixing agglutinous and other powders for clutriating siliceous
earth, carthy pigments, graphite, clay, gypsum and cement for the manufacture
of Turkey red oil for purifying oils by means of sulphuric acid, naphthalive,
anthracene, for nitrifying and other purposes.
In order to execute the above and all other similar operations the centrifugal
machine is constructed as hereinafter described with reference to the several
modifications which are illustrated by way of examples in the accompanying
drawings. The substance under treatment i.e., the materials to be incorporated
together, are first sifted through a number of sieves of "luffa sponge," cane
plaiting, wire gauze or other equivalent material rotating upon an axis.
"
Figure 1, shows, an ordinary rotary centrifugal drum in which is the drum or
frame and the axis: the frame is perforated as usual or made of plaited or
twisted wire.
Within this rotary centrifugal drum or vessel is placed a number of sieves or
perforated metal sheets such as cane plaiting, small pieces of plate, rings, or “luffa
sponge" which is indicated by in the drawings.
The rotary drum is set in motion. The materials under treatment which are
placed in the said drum, either beforehand or while the latter is in motion are
driven by centrifugal force with the aid of the sieves and of the drum or frame
towards the collecting space or chamber s. This chamber or collecting channel s
takes the form of a groove or flute within the casing g, as clearly shown in the
figures.
The whirling or agitating of the materials under treatment by centrifugal force
causes the particles thereof to beat against and collect upon the various perforated
surfaces or sieves, and thus effect a thorough mixing, emulsioning, washing, or
incorporation of such materials.
The sieves may as already stated be of different materials according to the
object in view, and may be modified in construction without departing from the
nature of my invention as already described with reference to Figure 1. As for
instance, in Figure 2, c is the drum in which are placed a series of cylindrical,
perforated rings or sieves 1, 2, 3, 4, 5, 6, 7, at suitable distances one from
another.
In Figure 3 a number of perforated rings or drums are placed in the drum
with the alternate spaces between two consecutive rings fitted with a porous
material.
In Figure 4 a series of rings are arranged in the manner shown with spaces
between each two consecutive rings.

page_text: In Figure 5 the sieves a consist of conical rings which are also similarly arranged
at a suitable distance from one another.
In Figure 6 the rings consist of round bars:
In Figure 7 the sieves consist of bars arranged parallel to the axis of the
rotary drum in the manner shown.
In Figure 8 the sieves consist of plates also arranged parallel to the axis of the
rotary drum in the manner shown.
In Figure 9 the sieves consist of zig-zag strips arranged in the manner
shown.
In Figure 10 the sieves are arranged outside the drum in the form of concentric
layers.
In Figure 11 bars are arranged radially to the rotary drum and parallel to the
axis thereof.
It is essential that in all cases the sieves are so constructed and arranged that
the materials under treatment in effecting a passage through them are continually
broken up and knocked about whereby the object in view whether mixing,
emulsioning, clutriating or the like operation is effectually carried out.
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 -
A centrifugal machine in which the rotary drum or vessel provided with a coating
or lining of sieve-like material or with several drums or frames is pierced or
perforated in such a manner that the whole of the material under treatment can be
driven out and broken up thereby for the purpose not of filtering or separating-but
of mixing, washing, uniting, or bringing the particles thereof into intimate contact
with one another, substantially in the manner as herein before described and
illustrated by way of example in the accompanying drawings.
Dated this 23rd day of June 1891.
