Improvements in and connected with Centrifugal Cream Separators,
and in Churns to be used therewith.
We THORVALD TAGE AGATON HANSEN, Civil Engineer and WILLIAM WALLIS
CLARK, Civil Engineer, both of Gainsborough Lincolnshire do hereby declare. the
nature of this invention to be as follows:-
This invention relates to (1) adapting to a centrifugal milk and cream separator
a churning and butter lifting arrangement by which butter can be made or extracted
from either cream or milk: (2) to adapting part of the above to a separator by
which it can be used at will either as a separator or as a churn capable of churning
either sweet or sour cream: (3) to a change in the interior of the milk holding
vessel whereby the creaming capacity of the separator is greatly increased: (4) an
arrangement for extracting the moisture from the butter while the churning is
going on (5) also means for washing the butter as it is made and while the
churning is going on, all these operations taking place together and going on
continuously.
According to the first two parts the churning appliance proper, consists of a
vessel to hold the cream into the mouth of which is fixed a short tube or throat
through which passes a fixed worm on the outside of the tube descending into the
cream vessel. This vessel is arranged upon the top of the milk holding vessel with
which it communicates by an opening in bottom, a corresponding opening being
made in the top of the milk vessel, through these passages the cream from the
separated milk rises into the cream vessel or churn in which it is churned into
butter, and the latter as made is worked up the throat by the aid of the worm and
overflows into a receptacle arranged to receive it from which it is withdrawn in any
convenient manner. It will be understood that the oream vessel revolves with the
milk vessel. To enable the ordinary separator to be used as a churn, the inter-
mediate cream vessel is not used but only the worm part which is fitted to the
milk vessel so, that it descends into same and cream is poured into this vessel
instead of milk, through the worm. By the above arrangement the continuous
making of butter can go on from new milk or cream, either being fed into the
apparatus from a suitable supply. According to the third part, the interior of the
milk vessel is divided into a number of small chambers which may be formed of a
number of concentrically placed rings with partitions: provision being made to
enable the milk to be introduced. According to the fourth part the throat or a
portion of it on which the worm is held is perforated with small holes which inay
be covered with cloth so that the moisture pressed out of the butter as it rises may
run through into a receptacle to receive it from whence it runs off. According to
the 5th part, the worm tube may have a second tube passing through for the
passage of the milk, the other space being for the inlet of water; on the outside
of the worm tube above and projecting over the worm and the mouth of the throat
is a tapered collar, and round the worm tube above this collar is a series of small
holes for water to run out which meets the exuding butter and washes it, the
water,running into the receptacle arranged to receive the butter, is prevented from
running into the cream by the centrifugal force of the separator which throws.it to
the outside from whence it runs off by suitable outlet after filtering through a ring
of cloth held a slight distance of the inside wall, this prevents butter from passing
away. The top of the butter holder is covered by suitable cover leaving a ring
opening all round edge to enable the. butter to work out if desired.

We THORVALD TAGE AGATON HANSEN formerly of Gainsborough, and now
of Raadhustroede 5 Copenhagen Denmark, Civil Engineer and WILLIAM WALLIS
CLARK now of 32 Windsor Road, Ealing in the County of Middlesex Civil
Engineer 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-1-adapting to a centrifugal milk and cream separator
a churning and butter lifting arrangement-2-to adapting part of the above to a
separator by which it can be used at will either as a separator or as a churn capable
of churning either sweet or sour cream or producing margarine from suitable
material such as oleomargine and earth-nut-oil-3-an arrangement for extracting
the moisture from the butter while the churning is going on-4- means for washing
or salting the butter as it is being made. All these operations may take place
together and go on continuously.
=
To enable this invention to be properly understood I will proceed to describe the
same with aid of. the accompanying drawing which is a sectional elevation of the
entire apparatus embodying the whole of the parts for the before mentioned
operations W is the main hoider for the cream which is fed to the apparatus
through the pipe Z the exit of which is controlled by a float with tapered spike
so that the cream in the receptacle e' may always keep at the same level the cream
then passes down the pipe 2 into the cylinder A and out through the bottom into a
chamber in which is fixed the usual form of wings common to this class of
separators through vertical holes (not shown) the cream by the centrifugal action
works up into the chamber V. In the middle of the chamber V are concentrically
arranged short tubes c d e. The tubes and e. have several small horizontally
slotted openings c', and the tubes d vertical openings; through these openings the
atoms of butter as made passes to the interior tube e after previously uniting
together by meeting each other in passing through these openings. On the outside
of the lower portion of cylinder A is a coarse screw thread A, which causes the
butter as it works into tube e to work up into the part E and is projected laterally
by the flange a. Fitted within the receiver E is a ring of perforated metal F
covered with a straining material such as coarse linen.
The revolution of the apparatus flings the butter as it rises against the part F
which causes the moisture to be pressed out which escapes at the hole g.. The
butter as it continues to increase on the strainer F gradually works itself up to the
top when it is caught by the spoons from whence it is easily removed, the moisture
which adheres to the butter prevents the latter sticking to the spoon. This is
preferably made of wood.
The colouring matter for the butter comes from the holder into the tube X
from which it passes into the cream so that it is intimately mixed with the same by
the churning process. For salting the butter brine is led from a suitablo receptacle
into the upper part of tube b the lower part of which passes round the cylinder A
and is perforated with small holes through which the brine runs out into the butter
when it is desired to wash the butter water is run out in place of brine when the
apparatus is used for the production of margarine the material used for this
production is fed from holder 2 down the pipe the inlet being regulated by the
regulator The butter milk passes out from the churn part V through the
vertical hole into a passage h³ and out through a hole h in the regulating screw
plug and out of the apparatus by the gutter y. When the apparatus is used as
a separator for separating cream from milk, the latter is passed in from holder W
as described for the cream, and the lattor when separated rises up as the butter

page_text: into E the strainer part F being removed the cream passes out at g into trough y¹
and the skimmed milk through plug into trough Y'.
The revolving part of the apparatus that is the part D and E revolves upon
pin H passing down tube I and resting upon ball M. The driving is by endless
cord on pulley L at bottom of sleeve L'.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
olaim is :-
1. In centrifugal churns of the character described, the use of the part A having
a thread upon same held within a throat into which butter as made or extracted
passes, to enable the butter to rise up into a chamber arranged to receive it, as
described and illustrated by the accompanying drawings..
2. In centrifugal churns of the character described, the use of tubes such as e de
with openings in same, arranged as and for the purposes described.
3. In centrifugal churns of the character described the use of a tube & to
introduce brine into the butter or water to wash same arranged substantially as
described.
4. In centrifugal churns of the character described the straining apparatus F,
arranged as and for the purposes described.
5. The combination with a centrifugal separator of the parts A and E to convert
the separator into a separator and churn at will.
6. A centrifugal separator and churn, constructed substantially as hereinbefore
described and illustrated by the accompanying drawings.
