Improvements in and relating to Centrifugal Milk Separators or
Creaming Appliances.
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 Middle-
sex, Civil Engineer, do hereby declare the nature of this invention (which has been
communicated to me by Georg Daseking, Manufacturer, of 179, Celler Chausee,
Hannover, in the Empire of Germany) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
1.
This invention relates to the separation of cream from "whole milk," and consists
in certain improvements in machines or appliances used in connection therewith.
which are an amplification of the invention which was communicated to me by one
Georg Daseking and for which Letters Patent were granted to me numbered. 122,.
and dated the 2nd of January, 1897.
The present invention resides in the arrangement attachment mounting and
carrying of the discs upon the hub or carrier, which is located within the drum
or barrel of the machine, the mounting of the said spindle of the said drum upon
its support so that a free and easy running is assured, and the method of cleansing
the drum and the discs contained therein.
In the accompanying sheets of drawings the invention is illustrated, and is
described in connection therewith by the aid of reference letters; Fig. 1 showing
a section of the whole of the machine or creaming appliance, whilst Figs. 2, 3, 4
and 5 are vertical sections and plans of the discs and how they are constructed
and carried. Figs. 6 and 7 are modifications of the discs.in Figs. 2 to 5, and
Fig. 8 is a vertical section showing the present invention applied to the arrange-
ment and form of discs set forth in the Letters Patent cited.
Fig. 1 is only a diagram other than in showing the mounting of the drum and
the discs to obtain a free running, and this latter is accomplished through the aid
of an anti-friction ball k, which intervenes between a seating in the top of the fixed
support, standing up from the machine's base, and a steel piece fixed in the
crown of the hollow spindle m which surrounds the support 7, so that although the
hollow spindle surrounds the support to keep the druin and its parts in position the
whole of the weight of the latter is borne by the said support through the anti-
friction roller k. The hollow spindle carrying the drum is clear of its mounting
at e¹, and the top of the support.is preferably flat as indicated at u, but it may be
concaved or sunken instead of flat.
In Figs. 2 to 5 the discs b are flat ones and have elevations, depressions, ribs
or outstanding parts 6 formed upon their faces, which cover each other and

page_text: •
combine to form, when the discs are together, the undulatory channels by which
the milk takes a circuitous or wavy course. These discs bare not attached rigid
to the carrier A, but some of them rest upon supports B, fixed to A some on
sliding supports B₁, attached to A and some on auxiliary sliding supports B
also attached to A, so that the pile of discs can be opened bellows-like, as in Fig. 3,
for cleaning purposes, when the supports B1 B2 are drawn up and be again closed
or collapsed into a working position as in Fig. 4 after having been cleansed. The
sliding supports B₁ are connected to the supports B, so as to slide vertically face to
face, by coupling studs D, as also are the auxiliary sliding supports B³ to the
supports B, and these latter are surmounted by and fixed to a collar or crown
plate E, which lies upon the highest disc. The lower supports B have each a
lever F upon their upper edges, for the purpose of locking the supports in the
position with the discs closed, as in Fig. 4, and upon their lower edges are project-
ing ledges G upon which the lower disc rests. The lever F is simply a catch, to
hold down the supports B1-B2 in their positions as shown in Fig. 4 and prevent
their displacement whilst the creaming operation is taking place. The discs are
connected to the particular supports B, B1, B2, which carry them, by parts S of
them being indented to fit over the edges of the particular supports by which they
are carried, so that they cannot slip or get away from the carrier A, but must
rotate with it.
It will thus be seen that when it is desired to clean the interior of the separator, it is
only necessary to remove the lid of the drum and elevate the pile of discs upon
their sliding supporting means, as shown in Fig. 3, to obtain access to the drum's
interior and also the tops and undersides of the discs..
For the purpose of cleansing the whole of the discs, which are united to form a
block, are divided into quarter blocks as shown in Figs. 6 and 7, the first named
fig, showing a set of such discs with a cover on, and Fig. 7 the same with the
cover off. The discs are divided into four blocks h, each of which consists of a
number of underlying quarter discs soldered the one to the other, so that the said
discs can be taken out of the separator bodily in piles and not one at a time as in
the first described arrangement.
Each quarter block or pile h is independent of the other so that each block can
be taken out of the barrel and put back again without disturbing the others.
When the blocks are in the barrel they are on a common level and are prevented
from becoming displaced during the revolution by partition walls I which are
arranged in the barrel for the pile of discs to come between.
If the barrel and quarter discs required to be cleansed each pile can be taken out
of the barrel by hand and cleansed separately which will admit of an empty barrel
being obtained for washing.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
:―
First. In a centrifugal creaming appliance the arrangement upon the carrier, so
as to be within the drum, of a pile of horizontally flat or mushroom-like discs b
having radial undulations, grooves, elevations or depressions, and which are adapted
to underlie one another upon the said carrier in such a way that the elevations and
depressions are exactly covered, in order to divert the "whole milk" and make it
take a circuitous course between the said discs, substantially as set forth.
Second. In centrifugal milk separators of the class described, mounting the
rotary parts thereof upon a stationary support through the medium of an anti-
friction ball or balls, substantially as set forth.
Third. In a centrifugal milk separator, arranging and carrying the revolving
discs so that their pile can be opened and closed for obtaining access to them and
to the drum for cleaning and other purposes, substantially as set forth.
Fourth. In a centrifugal milk separator having an arrangement of discs as
claimed in Claim 1, constructing and building up the said discs into single and

page_text: independent blocks, capable of being slid into and out of the drum for the purpose
of removing and replacing the said discs in a convenient manner, substantially
as set forth with reference to Figs. 6 and 7.
