Improvements in or relating to Centrifugal Milk Separators.
*I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E., of "The Agency for Foreign
Patent Solicitors, 11, Burlington Chambers, New Street, Birmingham, in the County
of Warwick, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in the
County of Lancaster, and 322, High Holborn, in the County of Middlesex, Civil.
Engineer, do hereby declare the nature of this invention (which has been communi-
cated to me by Georg Daseking of 179 Celler Chaussee Hanover in the Empire of
Germany Manufacturer) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention relates to a centrifugal creaming appliance or, in other words, to a
machine for the separation of cream from "whole milk," and the object of the inven-
tion is the separation of the same more quickly and effectively than hitherto.
Further the invention enables the separated cream, contained within the drum
after the creaming process has been finished, to be ejected therefrom without the
introduction of non-fatty liquids as in the usual method. The sectional figure shown
in the accompanying drawing illustrates the invention in a practical form, reference
letters being used to indicate the parts.
The drum a 2 which is provided with a lid a 3, is arranged to rotate within a casing d 1,
carried by a base m. Within this drum a 2, and centrally and fixedly mounted upon
the drum shaft, is an insertion or carrier a, consisting of a central hub part m 2, having
rigidly attached thereto a pile of circular and corrugated mushroom-like discs b
arranged one above the other and with their corrugatel parts or flutings coincident;
a space being left between each and every one of the said discs, so as to allow the
"whole milk" to freely circulate between them and to be operated upon. Around
the inside wall of the drum a 2 are stationed pipes d to conduct the skim milk into the
lower part of the casing d 1, and upon the drum lid a 3, as aforesaid, is provided an
adjustable cream outlet g, and a cock v, the former to conduct the separated cream
from the drum a 2 to the upper part of the casing d2 from thence it flows to its
delivery ; the cream flowing upwards from the drum to the said adjustable outlet at
the point f.
The cock v, which is fitted with a central piercing x, and a plug y, having a
handle z, is so arranged upon the lid of the drum that, on the drums rotation, it
comes underneath the hole i within the cover d 3 of the casing d 1, and is used for
taking from the said drum the cream left therein after the supply of "whole milk"
has ceased; a protuberance being inserted through the whole i, which comes in the
path of the cock handle z and opens the cock.
The corrugated or fluted discs 6 of the insertion or carrier a are conically disposed
in the drawings, but this is not necessarily so, as they may be horizontally disposed,
and the flutings thereof either straight or radiating, so long as the corrugated or
like sectional figure is retained. In their rotation, owing to their construction and
disposition, the discs b, of the insertion or carrier a, compel the milk within the
drum to take a circuitous course between each and every one of them and over and
under their corrugations, and by so doing the said milk is agitated and broken up
or separated into its constituent parts. The "whole milk" is fed through the con-
tainer n down the central shaft and into the drum a 2 in the direction of the arrows in
which said drum it rises by its own volume up to the point c circulating through
and between the discs b by reason of their outer edges 6 being left open and, on

page_text: the centrifugal action being started, the discs bagitate the "whole milk" and cause
it to be divided up into its constituent parts, the thick part or cream accumulating
towards the centre, by reason of the centrifugal action, (the position of the same being
indicated by the dotted lines e) whilst the skim milk passes away at the point c down
the conducting pipes d; the separated cream passing from the cream column (shown
in dotted lines) at the point through the cream outlet g, and so to its delivery h.
When the creaming process is finished, the cream contained within the drum is
obtained and prevented from uniting again with the skim milk by opening the cock v
and the continuation of the centrifugal action; the said cock being operated by the
insertion of a protuberance through the hole i which coines in the path of the cock
handle.z.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. In centrifugal separators the combination with the drum of an insertion or
carrier a, having corrugated or fluted discs 6 arranged one above another, or in a
pile so that their corrugations come coincident and a space left between them, for
the purpose substantially as described and set forth.
Second. In "whole milk" separators, the combination with a drum such as a 2 of
a cock or valve v, arranged to be opened during the working for discharging the.
cream remaining in the drum after creaming, substantially as described and set forth.
Third. In centrifugal separators of the kind described the general arrangement
and combination of the parts as set forth.
