PROVISIONAL SPECIFICATION.
Improvements in Centrifugal Apparatus for the Separation of Fats
or Grease from Liquors Containing Same.
I, JOSEPH GOMMESEN, of Wilson Street, Newtown, near Sydney, in the Colony
of New South Wales, Engineer, do hereby declare the nature of this invention
to be as follows:--
These improvements in centrifugal apparatus for the separation of fats or
grease from liquors containing same and particularly from those resulting from
the washing of sheep wool and skins and those resulting from operations in meat
preserving works and boiling down establishments and the like liquors have been
specially devised in order that the more or less valuable fats or grease in the said
waste liquors mentioned may be effectively separated from the useless and worth-
less matters therein.
Centrifugal apparatus for the separation of fats or grease from liquors contain-
ing same and particularly from those resulting from the washing of sheep wool
and skins and the like constructed according to this invention consist of a rapidly
revolving pan or basin having discharge orifice or orifices in the periphery
thereof though the orifice or orifices are conveniently through the circular part
of the periphery or casing of the pan or basin and at such height as will best
serve the purpose of allowing the heavier debris of the waste liquors to discharge
yet as an alternative the orifice or orifices might be through the top or bottom
of the basin in which case a pipe or pipes may be inserted therein terminating
at the desired level. Preferably in or on each orifice is an automatically operating
discharge or shifting valve.
In centrifugal apparatus constructed according to this invention the pan or
basin has at or near the upper part of its periphery (preferably an inverted conical
periphery) one or more discharge orifices. In or on each orifice there may be
and is preferably an automatic discharge valve of any desired construction. In
one form it may be an external valve held to a seat by a spring on its own
spindle the force of such spring being adjustable. In another construction when
it is an internal valve it may be hollow or be of material of low specific gravity.
so that it will open when the pressure of the material round it exceeds the centri.
fugal force keeping it on to its seat..

I, JOSEPH GOMMESEN, of Wilson Street, Newtown, near Sydney, in the Colony
of New South Wales, 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: —
These improvements in centrifugal apparatus for the separation, of fats or
grease from liquors containing same and particularly from those resulting from
the washing of sheep wool and skins and those resulting from operations in meat
preserving works and boiling down establishments and the like liquors have been
specially devised in order that the more or less valuable fats or grease in the said
waste liquor's mentioned may be effectively separated from the useless and worth-
less matters therein.
Centrifugal apparatus for the separation of fals or grease from liquors contain-
ing same and particularly from those resulting from the washing of sheep wool
and skins and the like constructed according to this invention consist of a rapidly
revolving pan or basin liaving discharge orifice or orifices in the periphery
thereof though the orifice or orifices are conveniently through the circular part
of the periphery or casing of the pan or basin and at such height as will best
serve the purpose of allowing the heavier debris of the waste liquors to discharge
yet as an alternative the orifice or orifices. might be through the top or bottomn
of the basin in which case a pipe or pipes may be inserted therein terminating
at the desired level. Preferably in or on each orifice is an automatically operating
discharge or suifting valve.
In centrifugal apparatus constructed according to this invention the pan or
basin has at or near the upper part of its periphery (preferably an inverted conical
periphery), one or more discharge orifices. In.or on each orifice there may be
and is preferably an automatic discharge valve of any desired construction: In
one form it may be an external valve held to a scat by a spring on its own
spindle the force of such spring being adjustable: In another construction when
it is an internal valve it may be hollow or be of material of low specific gravity
so that it will open when the pressure of the material round it exceeds the centri-
fugal force keeping it on to its scat.

But in order that this invention may be clearly understood reference will now
be made to the drawings herewith in which Figure 1 is a central sectional
elevation of the preferable construction of this improved centrifugal apparatus
for the separation of fats or grease from liquors containing same such as those
resulting from the washing of sheep wool and skins and the like in which the
pan or basin has the discharge orifices which are essential to its successful: opera-
tion and in which each discharge orifice has therein or thereon an automatically
operating discharge or, snifting valve though of these orifices there may be one
or two or more with or without valves. In the one pan illustrated the two
discharge or snifting valves are shown of different construction though it is to
be presumed all the valves in each pan would be identical Figures 2 and 2ª are
details of one construction of valve and Figures and 3 are details of another
construction.

The pan
'A has an inverted conical periphery at the larger diameter of which
is or are one or more orifices Bin or on which closes a valve C. In one con
struction of this valve it is an external valve (as shown in detail in Figures 2
and 2) held to its seat (with adjustable force) by spring on spindle C passing

page_text: through perforated guide block C. In another construction (shown in Figures 3
and 3) the valve proper C is a hollow or other light body supported by gudgeons C
in guides C+ depending from ring or annulus D.
In operation the liquor containing fats or grease and dirt, as say the conserved
waste liquor from sheep washing, wool washing, or skins washing, or the like,
flows from a convenient reservoir through pipe E'into the pan or basin A which
being revolved at a high rate of speed causes the water and the grease or fats to
vertically separate the latter forming a wall up. the inside of the body of water
and being skimmed away by pipe F. The water walling up between the layer
or wall of the lighter fats and the periphery of the pan or basin will be picked
up and conveyed away by pipe F and also will (according to the regulation of
the valve as may be required) discharge (or snift) away through the orifice or
orifices B.carrying with it any collection of heavier dirt wool shreds etc. which
partly owing to the taper of the periphery will rise up and gather round said valve.
It is to be noted that the presence of valve is not essential for in practice
there may be valves in or on the orifices or for these may be substituted pipes (the
diameter of said valveless orifices or pipes being regulated as experience directs)
the water will continuously flow away through said orifices (preferably having
renewable liners) carrying with it the heavier dobris.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
First. In centrifugal apparatus. of the class set forth the combination and
arrangement with the revolving pan or basin of one or more discharge orifices
(or as substitutes therefor one or more inserted pipes) at or near the upper part
and at or near the larger or largest diameter thereof substantially as herein
described and explained.
Second. In centrifugal apparatus of the class set forth the combination and
arrangement with the revolving pan or basin having one or more orifices at or
near its upper part of automatically operating discharge or snifting valves in or on
such orifices substantially as herein described and explained.
Third. The combination and arrangement together of the mechanical parts
(or their modifications) forming a centrifugal apparatus for the separation of fats
or grease from liquors containing same substantially as herein described and
explained and as illustrated in the drawings.
