A New or Improved Apparatus for the Combined Purposes of
Cleansing and Heating or Cooling Liquids.
LUCAS CLASSEY Beaumont Shepton Mallet No Occupation, do hereby declare the
nature of this invention to be as follows:-
A revolving drum or basket wholly or partly made of perforated or woven metal
or other suitable substance and containing felt, cloth, or other woven material,
sand charcoal or any other known filtrant or straining medium or any number of
various filtrants. The drum or basket may be made double or may contain one or
more other and smaller drums or baskets or may be constructed with inner circles
or bodies. These inner drums, baskets or circles may be wholly or partly filled
with filtering or straining mediums or combination of same or with different
filtrants or density of filtrants. The liquids to be treated are forced through the
filtering or straining mediums by centrifugal force or action and leave the rotating
drum or basket in fine spray or streams and may then be heated or cooled by either
of the following methods.:-
(A). By an outside jacket, cover, vessel or tubes wholly or partly filled with
water, steam or other heating or cooling medium or through which the heating or
cooling medium is caused to flow.
(B). By means of hot or cold air, steam or vapour passing into or through a space
between the rotating drum or basket and an outside cover or jacket.
A New or Improved Apparatus for the Combined Purposes of
Cleansing and Heating or Cooling Liquids.
I, LUCAS CLASSEY of Beaumont, Shepton Mallet, Butter Merchant, 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:-
The essential feature of my invention is the combination with a centri-
fugal strainer or filter of means for heating or cooling the liquid passed
through the said strainer or filter. In carrying my invention into effect I provide
a rotating drum or basket wholly or partly made of perforated or woven metal
or other suitable substances and containing felt, cloth, or other woven material,
sand, charcoal, paper or any known filtrant or straining medium or any number of
various filtering or straining media. This drum or hasket may be made double

page_text: or may contain one or more other or smaller drums or baskets or may be
constructed with inner circles or bodies and those inner drums, baskets or circles
may be wholly or partly filled with filtering or straining media or combinations of
the same or with different filtrants or density of filtrants. The liquids to be treated
are forced through the filtering or straining medium or through the various media
by centrifugal force and leave the rotating drum or basket in fine spray or streamis
and may then be heated or cooled by any suitable means. For instance there may
be an outer and double jacket surrounding the revolving basket and the space
between the jacket walls may be wholly or partly filled with heating or cooling
media or heating or cooling media may be allowed or caused to flow between the
walls of the jacket. The revolving drum or basket may be surrounded by a coil
or by coils through which circulate heating or cooling media. Another method
would be to allow hot or cold air, steam or vapor to pass into the space provided by
an outer casing of greater diameter than the revolving drum. As another method,
the outer casing may be lined with corrugated plate, the heating or cooling air,
steam or equivalent being caused to circulate between the corrugated plate and the
casing. As a simpler method the spray passing through the strainer or filter may
le discharged into the surrounding atmosphere.
In order that my invention may be more readily understood I make reference.
to the accompanying drawings in which Fig. 1 is a sectional side view showing
two ways of attemperating the liquid thrown out of the revolving drum, Fig. 2
a section of the outer casing and two alternative methods of effecting the above
purpose. Similar letters refer to the same parts wherever they occur. a is the
base of the apparatus and is surrounded at the top by the rim b. To the under side
of a is attached the hanger c supporting the spindle d which passes upwards
through the top of a and terminates in the conical part e, the top of a being
prolonged to form the bearing f to support the upper end of the spindle d. To d
is attached the bevel pinion g in which gears the bevel wheel h attached to one
end of the spindle i running in bearings j and k. At the other end of i is the
pinion which can he revolved by the internally toothed wheel m. The wheel m
is rotated by the handle o or by other suitable means, 7 being the spindle round
which m runs. Over e is placed the filter or strainer g having the outer perforated"
wall and if desired other perforated walls st & u. The space between any two
walls may be filled with any suitable filtering materials, for instance, there may he
a ring of felt v and a ring of sand w. When there are no inner walls the felt and
sand may be sufficient without a wall to keep up the sand, as the latter will
naturally fly out and spread itself over the felt by centrifugal force when the filter
is rotated: At all round the inner bottom corner of a is a sloping piece of metal,
under which the felt v beds itself when the filter is in use and thus prevents the
fluid driving under v. The fluid is fed in by the opening y and the whole may
be covered in by the outer casing against which the fluid strikes when it is thrown
out through r, and after striking it falls onto the top of a and out through the
spout A, or an exit may be provided for it by a downward tending tube opening
into the top of a. The speed of the spindle i may be regulated by any suitable
means such as by an ordinary strap brake acting on the pulley B attached to i.
The space C (Fig. 1) between wall ŕ of the revolving drum and the outer casing =
may be heated or cooled by the admission of hot or cold air, steam or vapor or the
space may be heated or cooled by a coil or by coils of piping D (Fig. 2) wholly or
partly filled with heating or cooling, or through which, heating or cooling medium
or media is or are allowed or caused to flow. Instead of a coil I may use a lining
of corrugated metal K (Fig. 2) the heating or cooling media wholly or partly filling
the spaces between the corrugations and the casing. In this case I prefer that the
corrugations shall not he parrallel with the upper edge of the casing, but somewhat
inclined thereto so as to constitute more or less spiral passages for the flow of the
heating or cooling medium or media. I sometimes make the outer casing with
double walls, as at F (Fig. 1), between which may be the heating or cooling medium
or media. With this modification I prefer to have at one part of the circumference

page_text: a partition connecting the inner and outer walls of the jacket and thus dividing
the space, the medium or media entering at the bottom of one side of the partition
and escaping at the top of the other side. The liquid may also be cooled or
attemperated by omitting the outer casing and spraying the liquid through the
perforated walls of the drum r into the surrounding atmosphere.
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:
1. The combination with centrifugal strainers and filters of a surrounding outer
jacket between the walls of which is allowed or caused to flow heated or cooled
air, fluid, steam or vapour, the whole substantially as described in the above
specification and exemplified in the accompanying drawings.
2. The combination with centrifugal strainers and filters of a coil or of coils of
piping through which are allowed or caused to flow heated or cooled air, fluid steam
or vapour, the said coil or coils being situated in the space between the revolving
drum or basket and its surrounding outer casing, the whole substantially as
described in the above specification and exemplified in the accompanying drawings.
3. In conjuction with centrifugal strainers and filters the use of heated or cooled
air, fluid, steam or vapour admitted into the space between the revolving drum or
basket and its surrounding outer casing, the whole substantially as described in
the above specification and exemplified in the accompanying drawings.
4. The combination with centrifugal strainers and filters of a corrugated plate
in contact with the inner surface of the outer casing, the spaces between the
corrugations and the casing forming passages for the admission and circulation of
heated or cooled air, fluid, steam or vapour, the whole substantially as described
in the above specification and exemplified in the accompanying drawings.
5. Attemporating liquids by throwing them by centrifugal force through the
wall or walls of a rotating drum or basket into the surrounding atmosphere
substantially as described in the above specification.
6. The combination with centrifugal strainers or filters of means for attem-
perating the fluid thrown through the wall or walls of the rotating drum or basket
of the said strainers or filters the whole provided for and operating substantially
as described in the above specification and exemplified in the accompanying
drawings.
