Foreign Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn, in the
County of Middlesex, Civil Engineer do hereby declare the nature of this
invention to be as follows:-
:―
To separate, in centrifugal machines, the heavier parts of the liquid from the
lighter parts, it is desirable to give an upward and downward motion to the
liquid.
For this purpose, diaphragms are placed in the drum through which the liquid
must pass in order to have an undulating motion. Therefore, two slots are cut in
the diaphragm in a horizontal direction one above the other. On both sides of the
diaphragm, caps are attached, furnished also with holes which are placed between
the holes in the diaphragm. If now the machine rotates, the liquid entering the
hole in the cap must pass through the upper or the lower slots in the diaphragm
and be driven out through the middle aperture in the second cap. Thus the liquid
receives the undulating motion.
A modification in this arrangement may be made by placing a single hole in the
diaphragm, and by arranging double caps on both sides. Thus a double undulating
motion is obtained.

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street,
Manchester both in the County of Lancaster, and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 :-
To separate, in centrifugal machines, the heavier parts of the liquor from the
lighter parts, it is desirable to give an upward and downward motion to the fluid.
For this purpose, holes or slots are formed in the diaphragms of the drum
through which the fluid must pass by making an undulating motion.
In the accompanying drawings,
Figures 1 and 2 show the improved drum in sectional elevation (Figure 1 being
a section on line I II III of Figure 2).

page_text: In Figure 1 the undulating movement is obtained by cutting large horizontal
holes or slots oo in the diaphragm w and by attaching on both sides of the
diaphragm caps p also furnished with holes i which are placed between the holes o o
of the diaphragm 0.
By turning the drum, the liquor entering through the hole i must pass through
the upper and under apertures oo of the diaphragm and is driven out through the
aperture in the second cap as indicated by the arrows.
In the construction shown by Figures 3 and 4, two double caps p¹ p² are placed
before and behind the slot o in the diaphragm w. Here the liquor enters at the
middle of the fore cap p', passes (above or beneath) through the holes ii in the
second cap and enters the hole o in the middle of the diaphragm w.

motion which is effected by the caps
To obtain a more striking or jerking
by Figure 4 are employed.
The caps p and p' are not closed on both sides but open to let the liquid enter
and go out also at the side. Otherwise the agitation of the liquor would be
restricted.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is―
A centrifugal machine characterised by horizontal slots o cut in the well known
diaphragms and by the application of single or double caps p and pl placed on
both sides of the diaphragm w and also furnished with horizontal slots i transposed
against the slots o, the whole arranged for giving the liquor a vertical up and
down motion (Figure 1) or a double undulating motion, (Figures 3 and 4) substan-
tially as described and illustrated.
