PROVISIONAL SPECIFICATION.
Improvements in Centrifugal Apparatus for Separating Milk.
A communication from SVEN Jönsson, of Schönbergsgade 18, Copenhagen,
Denmark.
I, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Patent Agent, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in centrifugal apparatus for separating
milk and has for its object to obtain the greatest possible utilization of the
centrifugal apparatus.
In apparatus of this kind there has been employed an intermediate bottom or
horizontal partition at whose edge the skimmed milk was conveyed away. One or
more pipes have also been employed in place of this intermediate bottom which
pipes received the skimmed milk and conducted the same further towards the
centre.
In the first mentioned arrangement there is however the disadvantage that a
portion of the height of the centrifugal apparatus is lost for the centrifugal action,
whilst a portion of the centrifugal apparatus is filled only with skimmed milk.
On the other hand the second arrangement, namely that of the pipes, has the
disadvantage that the milk is taken up only at separate points at the periphery, and
not, as is desirable, along the whole periphery.
The present invention is designed to combine the advantages of both of these
arrangements without incurring the disadvantages of the same.
This is effected by means of the construction illustrated in the accompanying
drawing.
A is the cylinder proper, D the vanes, B is an annular recess or chamber
extending along the periphery for the reception of the skimmed milk, and C a pipe
which conducts it from the recess and towards the centre, where it is led away.
As can be easily seen the skimmed milk is in this case taken up along the entire
exterior of the drum whilst the working space in the drum is not reduced to any
considerable extent.
It is obvious that two or more pipes C can be employed if desired.

COMPLETE SPECIFICATION.
Improvements in Centrifugal Apparatus for Separating Milk.
A communication from SVEN JÖNSSON, of Schönbergsgade 18, Copenhagen,
Denmark.
I, WILLIAM LLOYD WISE of 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Patent Agent, 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 invention relates to improvements in centrifugal apparatus for separating
cream from milk and has for its object to increase the efficiency of such apparatus.
In apparatus of this kind there has been employed an intermediate or false
bottom, or horizontal partition, from the edge of which the skim milk was conveyed
Price 8d.1

page_text: away; also in place of this intermediate bottom or partition one or more pipes
have been employed which received the skim milk and conducted it towards the
centre of the apparatus.
In the first mentioned arrangement, there is however the disadvantage that a
portion of the height of the apparatus is not available for acting centrifugally on
the new milk because a portion of the apparatus is filled only with skim milk. In
the secondly mentioned arrangement there is the disadvantage that the milk is
taken up only at separate points at the inner periphery, and not, as is desirable,
along the whole inner periphery of the apparatus.
The present invention is designed to combine the known advantages of both
these arrangements whilst obviating the disadvantages referred to, for which
purpose centrifugal apparatus is constructed as shown in vertical section and plan
in the drawings left with my Provisional Specification.
A is the rotary drum or cylinder proper of the apparatus which is arranged to be
driven in any suitable manner; and DD are the fixed vanes therein.
B is an
annular recess or channel extending around the upper part of the inner periphery
of the cylinder for the reception of the skim milk, and C is a pipe, which conducts
the skim milk from this recess or channel towards the centre of the apparatus
whence it is led away to any desired place. This recess or channel is in the example
shown formed by the upper part of the vessel A and a downwardly projecting
curved extension of the cover of such vessel, an annular opening being left between
the two for the entrance of the skim milk.
As can be easily seen, the skim milk will, with the construction described, be
taken up around the entire inner periphery of the cylinder, whilst the working
space in the cylinder is not reduced to any considerable extent.
It is obvious that two or more pipes C can be employed if desired.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed declare that what I
claim is
:-
The construction of centrifugal apparatus for separating cream from milk, etc.,
with a recess or channel extending around the inner periphery of the cylinder for
the reception of the heavier liquid, and with one or more pipes for conducting such
liquid from the said recess or channel towards the centre of the apparatus whence
it is discharged, substantially as herein described.
Dated this 4th day of January 1892.
