Improvements in Centrifugal Separating Machines.
I WILLIAM WORBY BEAUMONT of 229 Norwood Road Herno Hill London S.E.
Engineer do hereby declare the nature of this invention to be as follows:-
In the construction of a simple form of centrifugal machine for separating liquids
into their components and more especially for separating cream from milk I use
preferably a vertical drum or container arranged so that one liquid may be taken off
at one end or at the top & the other from the other end or bottom thereof. Ι
prefer to use a drum of cylindrical form and to mount it upon a vertical spindle
the upper part of which is provided with a disc having a flange for carrying the
cylindrical part of the drum and forming one of its ends or bottom. Through a
hole or holes or passages in this bottom or within the thickness thereof one liquid
say the cream passes and the holes or passages may be covered with a device con-
sisting of or containing a conical valve or cone ended screw and so placed that
the exit is at approximately the same distance from the axis of the vessel as the
exit for the other liquid say skim milk from the top of the vessel. The top end
of the drum consists of an annular and flanged cover attached to the upper end
of the cylinder and provided with a central opening with level edges or upwardly
projecting flanged edges and also provided with a lip or a hole or holes or passages
for the egress of the one liquid the quantity of liquid that may pass being regulated
by the size of the hole, holes or passages or notches in the lip or adjustable by
means of a screw or valve or holes may be provided with bushes of adjustable
sizes or with teats. The escaping liquids pass into annular trays provided with
spouts and suitably supported from the frame of the machine. The spindle is carried
by a bearing at its upper part this bearing being on an elastically held support
and free to move through a small range in any direction. The toe at the lower
end of the spindle rests in a cavity in a piece of caoutchouc or composition, lead
or lead alloy or a solidified mixture of ground or granulated cork or sawdust and
boiled linseed oil & driers, the piece of the one or other material being tightly held
in a box rotating at a speed at which it is necessary to drive the spindle. In
some cases I connect the lower and upper ends of the drum by means of a tube
screwed or otherwise fixed into the lower end on the top of the spindle and to the
upper end by similar means. The sweet milk is fed into this tube or into the open
drum or a short tube.

Improvements in Centrifugal Separating Machines.
I, WILLIAM WORBY BEAUMONT of 229 Norwood Road, Herne Hill, London S.E.
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 :-
My invention consists in a simple form of centrifugal machine for separating liquids
into their components and more especially for separating milk into its components
cream and skim milk. A machine constructed according to my invention is shewn in
the accompanying drawing, figure 1 being a side elevation partly in section of the
drum and other parts. Figure 2 is a sectional part view of modified construction of
drum, and figure 3 half sectional elevation of a drum showing a modified arrange-
ment of the skim milk outlet passages.
The drum or container by preference vertical as here shown is so arranged that one

page_text: liquid is taken off at one end, the top, and other liquid at the other end, the bottom.
The drum is shown of a cylindrical form mounted upon a vertical spindle A the upper
part of which is provided with a disc A¹ having a flange for carrying the cylindrical
part B of the drum, being screwed into the same, and forming one of its ends, the
bottom in this case. Through one or more holes or right angled passages, a, a', a²,
in this bottom A' or within the thickness thereof, one liquid, say the cream,
passes.
The holes or passages may be covered with a device such as the screwed cap
or teat. a³ having a hole smaller than the hole a². To vary the efflux of cream I put
on caps each having a different sized hole through. The cap is so placed that the exit
is at approximately the same distance from the axis of the vessel or drum as the exit
for the other liquid say skim milk from the top of the vessel.
Instead of the right angled passage a, a, a², with cap a³ I may as shown in
figure 3 let the cream escape by a hole a direct to the hole in a cap a³, the skim milk
escapes by the passage c, c¹, c², c³, the exit being regulated by the cone pointed
screw as required.
The top end of the drum Fig. 1 consists of an annular and flanged cover C attached
by screwing to the upper end of the cylinder B and provided with a central opening D
with bevel edges at d d (or upwardly projecting flanged edges) and also provided
with one or more right angled holes or passages c c c² ca for the egress of the skim
milk, the quantity of same that may pass being regulated by the size of the
passage or passages (or notches in the lip) or adjustable by means of a screw c¹ or
valve.
The escaping liquids pass into annular trays E and F provided with spouts E¹ F¹ as
usual, such trays being supported from the frame G of the machine in the manner
shown viz. by means of the ring H with slots for screwed supports H¹ and by the
ring I.
The spindle A is carried by a bearing K at its upper part, this bearing being
on an elastically held support the rubber ring L being interposed between the
bearing K and the ring H, so that the bearing K is free to move through a small
range in any direction. The bearing K may be combined with its support H by
means of a rubber ring L as shown or may be fitted or formed in one piece
herewith.
The sleeve O fits on the spindle A and contains a number of rings o fitting
therein. Interposed between them and fitting on the spindle are a number of rings o
There is play between the spindle and the rings o and between the sleeve O and the
rings o¹. Hence the spindle with its assemblage of rings o¹ has slight lateral play
in the sleeve O with its rings 0. The sleeve is elastically supported by spring P
which rests on the adjustable collar P¹, the spring bearing on an intermediate loose
washer P.
The spindle A is driven at the required speed in any suitable manner.
The sweet milk is fed into the receiver M fixed in the lower part of the separating
drum from the pipe N and supply vessel N¹ and flows out into the drum by one or
more pipes m Fig. 1. Or; as shown in Fig. 3, I provide one straight pipe m and say
two pipes m² m² discharging at different heights.
Instead of discharging the cream at one end and the skim milk at the other end of
the drum I may, as shown in dotted lines at a Fig. 1, also discharge the cream at
the top at a different part of the circumference to the skim milk hole c
-
The drum is provided with the usual internal vanes though not shown on the
drawing.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. Constructing a centrifugal separator drum of a bottom disc fixed or formed on
the top of the drum spindle, a top cover, and an intermediate tube held between the
top cover and the bottom, substantially as described and shown.

page_text: 2. The means for rendering the spindle of a centrifugal separator drum laterally
self-adjusting, consisting of washers fitting in a sleeve which rotates in a neck bearing
with the spindle, and washers fitting on the spindle itself and arranged alternately
with the first named washers, clearance being provided between the first named
washers and the spindle and the last named washers and the sleeve, substantially as
described and shown.
3. Providing the central feed supply receptacle of a centrifugal separator drum
with two or more exit tubes for distributing the feed at different heights substantially
as described and shown.
having the passages for the escape of the separated
4. The drum covers A¹ and
liquids substantially as described and shown.
