Improvements in Centrifugal Separating Machines.
I, FREDERICK JOHN BROUGHAM, of No. 46 Lincolns Inn Fields in the County of
Middlesex, Managing Clerk, do hereby declare the nature of this invention to be as
follows :-
This invention relates mainly to the arrangement of a passage in the drum for the
escape of the skim milk.
A machine according to this invention is shewn by way of example in the annexed
drawing, only those parts being shewn that are necessary to enable the invention to
be understood.
Fig. 1 is a vertical section through the drum.
Fig. 2 is a horizontal section on the line X X Fig. 1; and
Fig. 3 is a horizontal section on the line Y Y Fig. 1.
A is the drum which may be of any suitable form. The milk to be treated flows
from M through the tube N, opening 6 and tube C into the drum. O is the outlet
for the cream which is conveyed thence through Q and Q into a receptacle. L is
the outflow opening for the skim milk which passes thence through P and P" to a
receptacle.
The outflow openings for the milk may if desired be suitably regulated.
The passage for the skim milk is between the partitions R and P. These partitions
fit close up against the wall A of the drum, as shewn in the drawings, with the
exception of an opening a in the lower part of the partition R. Or instead of this
arrangement one or both of the partitions may stop short of the wall of the drum, in
such a manner as to leave a narrow passage through which the skim milk may pass
into the space between the two partitions R and P. The outflow L is situated between
these two partitions.
The milk passes through the tube C into the drum where immediate separation into
cream and skim milk takes place in the usual manner, the skim milk forming an outer
ring, and the cream an inner ring. The skim milk then passes through the opening a
or equivalent into the space between the partitions R and P ; rises up between those
partitions, and passes through the outflow opening L into the outflow conduit P¹ P,
whilst the cream passes through the outflow pipe Ŏ into the outflow conduit Q Q¹.

Improvements in Centrifugal Separating Machines.
A communication from SVEN JÖNSSON, of Copenhagen, Denmark, Engineer.
I, FREDERICK JOHN BROUGHAM, of No. 46 Lincolns Inn Fields, in the County
of London, Managing Clerk, 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 of improvements in centrifugal separating machines relates mainly
to the arrangement of a passage in the drum for the escape of the skim milk.
Apparatus according to the invention is shewn in the drawing filed with my
provisional specification, only those parts of the machine being shewn that are
necessary to enable the invention to be understood.

page_text: Fig. 1 is a vertical section through the drum.
Fig. 2 a horizontal section on the line X X Fig. 1, and
Fig. 3 a horizontal section on the line Y Y Fig. 1.
A is the drum which may be of any suitable form. The milk to be treated flows
from the vessel M through the tube N, opening and tube C into the drum. O is
the outlet for the cream which is conveyed thence through Q and Q¹ into a receptacle.
Lisi the outflow opening for the skim milk which passes thence through the chamber P¹
and tube P to a suitable receptacle.
The outflow openings for the milk may if desired be suitably regulated.
The passage for the skim milk is between two partitions R and P. These partitions
fit close up against the wall A of the drum, as shewn in the drawings, with the
exception of an opening a in the lower part of the partition R. Or instead of this
11 arrangement one or both of the partitions may stop short of the wall of the drum, in
such a manner as to leave a narrow passage through which the skim milk may pass
into the space between the two partitions R and P. The outflow L is situated between
these two partitions:
C...
The milk passes through the tube C into the drum where immediate separation into
cream and skim milk takes place in the usual manner, the skim milk forming an outer
ring, and the cream an inner ring. The skim milk then passes through the opening a
or equivalent into the space between the partitions R and P ; rises up between those
partitions and passes through the outflow opening L into the outflow conduit P¹ Pi,
whilst the cream passes through the outflow pipe O into the outflow conduit Q Q¹.
Having now particularly described and ascertained the nature of the said inven
tion and in what manner the same is to be performed I declare that what. I
claim is
A centrifugal separating machine for treating milk, constructed with a passage
bounded by two partitions R and P which extend close up to the inner surface of the
drum, and between which is an upper outflow opening for skim milk, the partitions
being arranged in such a manner as to provide a narrow passage between the outer
edge of one or both of the said partitions and the adjacent surface of the wall of the
*drum for the passage of skim milk.
