Improvements in Centrifugal Apparatus for Separating Cream from
Milk.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
This invention relates to centrifugal apparatus for separating cream from milk
and has for its object to increase the efficiency of such apparatus and obtain the
greatest quantity of cream from the milk.
On the inner periphery of the drum of the apparatus are arranged a number of
oblique and twisted vanes, against which the milk is pressed on being forced
upwards in the drum in consequence of the centrifugal action, the heavier particles
of the milk passing without difficulty upwards along the periphery of the drum, in
order to leave finally through the outlet pipe for the milk, whilst the forcing back
of the cream in opposition to the centrifugal force is facilitated by the fact that the
cream, by reason of the velocity of rotation, is compelled to follow the twisted
vanes, simply passing along the latter to the outlet.
In carrying this invention into practice a centrifugal drum is provided, into which
the fresh milk conducted through a central inlet pipe extending nearly to the
bottom. The skim milk and the cream leave through their respective outlet pipes
at the top.
Any suitable number of oblique and twisted vanes may be employed in the drum
and the degree of their twist may be varied within wide limits.
The vanes are twisted from the top to the bottom and directly join the periphery
of the drum so that along this periphery are formed a number of cells or spaces
which are bounded on three sides and in which the milk is forced upwards during
the centrifugal action, separating the milk and cream.

Improvements in Centrifugal Apparatus for Separating Cream from
Milk.
I, HENRY HARRIS LAKE, of the Firm of Haseitine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 centrifugal apparatus for separating cream from milk
and has for its object to increase the efficiency of such apparatus and obtain the
greatest quantity of cream from the milk.
According to the said invention I arrange on the inner periphery of the drum of
the apparatus, a number of oblique and twisted vanes against which the milk
impinges on being forced upwards in the drum in consequence of the centrifugal
action, the heavier particles of the milk passing without difficulty upwards along
the periphery of the drum, and finally passing out through the outlet pipe, whilst
Pin 21

page_text: the forcing back of the cream in opposition to the centrifugal force is facilitated
by the fact that the said cream, by reason of the velocity of rotation is compelled
to follow the twisted vanes, simply pass along the latter to the outlet.
In the accompanying drawing
Figure 1 is a vertical central section through the improved centrifugal drum and
Figure 2 is an horizontal section of the same on the line a b c d.
A is the centrifugal drum into which the fresh milk is conducted through a
central inlet pipe, not shown extending nearly to the bottom of the drum. The
skim milk and the cream pass out through their respective outlet pipes m and s at
the top.
Any suitable number of oblique and twisted vanes B may be employed in the
drum and the degree of twist may be varied within very wide limits.
The vanes are twisted from the top to the bottom and are connected to the
periphery of the drum so as to form a number of cells or spaces around the said
periphery which are enclosed on three sides and in which the milk is forced
upwards during the centrifugal action, separating the milk and cream.
Having now particularly_described and ascertained the nature of my said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
A centrifugal apparatus for separating cream from milk the inner periphery of
which is provided with oblique or twisted vanes (B) which are connected to the
periphery of the drum in order to conduct the cream inwards and upwards.
