page_text: I, WILIAM LLOYD WISE, of No 46 Lincolns Inn Fields, in the County of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature of
this invention to be as follows
-
This invention relates to centrifugal cream separating apparatus (hereinafter
referred to as " separator") so constructed that the outflow of cream can be regulated
during the working of the separator, whereby the maximum useful effect of the
separator is ensured
A construction of separator according to this invention is illustrated in the annexed
sheet of drawings
Fig 1 showing the improved separator in section
Fig 2 being a plan thereof, and
Fig 3 a section to a larger scale of the upper portion of the separator
The improved centrifugal separator is supported upon standard A in the lower
part of which 19 situated a shaft B having a belt pulley C to which power can be
Transmitted from any convenient source
Upon the upper end of the shaft B rests the shaft D of the centrifugal separator,
which is forced to partake of the rotary movement of the shaft B by means of a
horizontal pin on the one shaft which engages in a slot in the other
The shaft D rests in a bearing E which is rendered elastic by means of a rubber
ring E and which is lubricated by lubricant coming through a pipe f from an oil
vessel F
The shaft Dat its upper end carries a dish to which is rivetted or otherwise
fastened the cylindrical drum or separating vessel G This vessel G is contrary to
the usual practise in the construction of cream separators, made of small diameter,
whereby its manufacture is facilitated, and a better product is obtained from the

page_text: machine There is also the great advantage that the cream leaves the separator
without froth, as the milk practically fills the whole space of the separator drum so
that there is hardly any air in the same, moreover by this means there is only a very
slight resistance of the air against the outer wall of the cylinder during rotation,
and consequently only a very small consumption of power in proportion to useful
work
The drum G is provided internally with a tube G¹ having three vanes or wings Gil
which at their free edges are held each by means of a projection fixed to the wall
of the drum and a hook rivetted to the vane so that the tube together with the vanes
can be readily disconnected and taken out
Thus the separator drum or vessel can be easily cleaned as it is quite smooth inside
when the inner filling pipe with the vanes has been removed
The drum or vessel G is closed at the top by a screwed cover H in which are
inserted two milk pipes each of which has one end open inside the cover, whilst the
other ond passes through the wall of the cover
The cover H has a central opening in which is screwed a tube I (provided with a
flinge 1) that extends above the upper end of the pipe G¹ is shewn The separating
vessel or dium is thus quite closed in contradistinction to others as heretofore
constructed Iwo or more vertical holes are formed in the flingo 1¹
Around the tube is provided another tube K having an upper flange and lower
flange ki As in any conical pegs k¹¹ are screwed into the lower flange k¹ as there
aro holes in the flange I' each peg corresponding to one hole
A spiral spring L is inserted between the tubes I and K and has constant
tendency to raise the latter (K) This tendency is counteracted by a nut M which
presses against the upper flange k and which is screwed in projecting arm N
(carried by the standard of the separator) and surrounds the pipe K The nut is
provided with serrated flange against which bears a roughened spring O so that
the nut is prevented from rotating with the tube
Instead of the nut M, there may be employed screws that can be screwed simul-
taneously agunst the flinge k Or a number of eccentric discs may be used by
simultaneously rotating which the tube K can be forced down more or less, or other
suitable arrangements may be employed
The milk which is to be centrifugally treated, is fed from a containing vessel P to
the drum G through the pipe G¹
After treatment in the drum G the milk passes out through the pipes h and
through the cover H, and is collected in a receiving vessel q whence it flows through
the pipe q¹
The separated cream passes out through the openings under the flange k¹ into
the receiving vessel S, which is provided with the outlet pipe S¹
The quantity of the outflowing cream can be regulated, even during the operation
of the machine, by screwing the nut M, whereby the conic il pegs k" on the flange k¹
are more or less rused out of the holes or are depressed to a greater depth in them,
so that the passage is widened or contracted
It will be evident that the separator may be arranged in such a manner that the
discharge will be effected below instead of at the top as shown

I, WII LIAM LLOYD WISE, of No 46 Lincolns Inn Fields in the County of Middlesex,
Consulting Engineer and Patent Agent, do hereby declare the nature of this invention,
and in what minner the sam is to be performed, to be particularly described ind
ascert uned in and by the following statement
This Invention relates to centrifugal cream separating apparatus (hereinafter
called sepator) so constructed that the outflo of cream can be regulated
during the working of the separator, whereby the maximum useful effect of the
separator is ensured
A construction of separator according to my invention is illustrated in the sheet
of drawings filed with my Provisional Specification Fig 1 showing the improved
separator in section, Fig 2 being a plan thereof and Fig 3 section to a larger scale
of the upper portion of the sepirator

The improved centrifugal parator is supported upon a standard A in the lower
part of which is situated a shaft B having a belt pulley C to which power can be
transmitted from any convenient source
Upon the upper end of the shaft B rests the shaft D of the centrifugal
separator, which is forced to partake of the rotary movement of the shaft B
by means of a horizontal pin on the one shaft which engages in a slot in
the other
The shaft D rests in a hearing E which is rendered elastic by means of a rubber
ring E and which is lubricated by lubricant coming through pipe f from an oil
vessel F
The shaft D at its upper end carries a dish to which is rivetted or otherwise
fastened the cylindrical drum or separating vessel G This vessel G is, contrary to
the usual practice in the construction of crem separators, made of small diameter,
whereby its manufacture is, facilitated and better product is obtained from the
machine There is also the great advantage that the cream leaves the separator
without froth, as the milk practically fills the whole space of the separator drum, so
that there is hardly any air in the same, moreover by this means there is only
a very slight resistance of the air agunst the outer wall of the cylinder during
rotation, and consequently only a very smill consumption of power in proportion to
useful work
The drum G is provided internally with a tube G¹ having three vanes or wings G
which at their free edges are held each by means of a projection fixed to the wall of
the drum and a hook rivetted to the vane so that the tube together with the vanes can
be readily disconnected and taken out
Thus the separator drum or vessel can be easily cleaned as it is quite smooth inside
when the inner filling pipe with the vanes has been removed
In some cases to facilitate cleaning, the separator drum or vessel G may be
constructed in two parts that are adapted to be secured together, as for instance, by
screwing
The drum or vessel G is closed at the top by a screwed cover H in which are
inserted two milk pipes, each of which has one end open inside the cover, whilst the
other end passes through the wall of the cover

page_text: The cover H has a central opening in which is screwed tube I (provided with
flinge I) that extends above the upper end of the pipe G¹ as shewn The separating
vessel or drum is thus quite closed in contradistinction to others heretofore constructed
Two or more vertical holes are formed in the flinge I'
Around the tube I is
and a lower flange k¹
flinge k¹ as there are holes
provided another tube K having in upper flange
As many conical pegs ¹ are screwed into the lower
in the flange I, each peg corresponding to one hole
A spiral spring L is inserted between the tubes I and K and has a const int
tendency to raise the latter (K) This tendency is counteracted by a nut M, which
presses against the upper flange k and which is scrowed in a projecting arm N
(carried by the stand ird of the separator) and surrounds the pipe K The nut is
provided with a serrated flinge against which bears a roughened spring O, so thit
the nut is prevented from rotating with the tube
Instead of the nut M there may be unployed screws that can be screwed
simultaneously against the flange k Or a number of eccentric discs may be used by
simultaneously rotating which the tube K can be forced down more or less, or other
suitable arrangements may be employed
The milk which is to be centrifugally treated, is fed from a containing vessel P to
the drum G through the pipe G¹
After treatment in the drum G, the mik passes out through the pipes / and
through the cover H and is collected in a receiving vessel g whence it flows through
the pipe q¹
The separated cream passes out through the openings under the flange k¹ into the
receiving vessel b which is provided with the outlet pipe S'
The quantity of the outflowing cream can be regulated, even during the operation
of the machine, by screwing the nut M whereby the conic il pegs k¹ on the flinge k¹
are more or less raised out of the holes or are depressed to a greater depth in them
so that the passage is widened or contracted
It will be evident that the separator may be arranged in such a manner that the
discharge is effected below instead of at the top as shown
Having now particularly described and ascertained the nature of my sud
invention and in whit manner the same is to be performed I declare that what
I claim 1s
1 In a centrifugal separator, the use for regulating the outflow of cream during
the operation of the machine, of a device, such as the nut M or equivalent mechanism,
which does not participate in the rotation, in combination with i device such as the
casing K or its equivalent which does participate in the rotation of the centrifug il
apparatus substantially as described
2 In a centrifugal milk separator a centrifugal drum or vessel closed at both top
and bottom substantially as described
3 A centrifugal unlk separator comprising a completely closed drum or vessel G
which can be divided into two parts and which is provided with vancs G" pipe h
and holes c capable of being regulated by mɩɩns of conic il or inclined or bevelled
pegs or pins k¹ or other equivalent arr ingements all substantially is described and for
the purposes specified
