PROVISIONAL SPECIFICATION.
Improvements in and relating to Centrifugal Separating Machines.
I JOHN LOWE No. 22 Market Street Droylsden Manchester Clerk do hereby
declare the nature of this invention to be as follows:-
To utilise the hydro extractor at present in general use for extracting water
from fabrics or other goods in the process of manufacture by rendering the same
capable of extracting water from its precipitated impurities or in other words
converting the same into a water filter.
The invention consists in constructing within the outside rim of the cage of the
said hydro extractor a cavity of sufficient extent to hold sand or other straining
material in such quantity as will constitute a complete water filter, the said sand
or other straining material to be securely held in its place by a lid or cap so
that the sand or other straining material with which the cavity is charged shall
not be disturbed either by the extreem velosity of the cage nor by the rapid
transit of the water as the filtration proceeds.

Improvements in and relating to Centrifugal Separating Machines.
JOHN LOWE No. 22 Market Street Droylsden Manchester Clerk. I 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:
Filtering muddy waters or other liquids where precipitated and other insoluble
matters are present, relates to centrifugal separating machines for continuously
filtering and extracting water from its insoluable impurities. The hydro extractor
is a machine at present in somewhat general use for extracting water and other
liquids from calico cloths yarns and other fabrics by means of centrifugal force.
Fig. No. 1 shows a form of such machine which by certain internal fittings
attached to and within the centrifugal cage give facilities for the purification of
water and constitute an improvement in the machine, and thereby inhanses its
utility. This invention consists in the construction within the outside rim of the
centrifugal cage of the ordinary hydro extractor or the one commonly in use for
the purposes herein before named. A cavity by the insertion of another rim of
perforated zinc or copper inside the rim already constituting the centrifugal cage
and at a suitable distance from it and the same depth from top to bottom the
cavity or sand chamber need not necessarily be more than eight inches from the
outside to the inside rim of the cavity, this sand chamber to be lined next to
the metal with good brass or copper gauze wire two folds on the outside and one
fold on the inside rim, and also a further lining of woollen felt upon the gauze wire
to prevent the sand from escaping. The chamber is filled with sea or other
suitable sand to its utmost capacity, this sand when evenly washed down so as to
attain a proper bedding must be held in its place and prevented from rising or
otherwise becoming loose, by bolts from the bottom and centre of the cavity, and
screwed to holding down plates, fitted entirely to cover the top of the sand
chamber so that the same and other filtering media with which the cavity is

page_text: charged shall not be disturbed either by the extreem centrifugal motion of the cage
or the rapid transit of the water as filtration proceeds. Inside the centrifugal cage
already fitted up, shall be fitted and placed another cage but instead of being con-
stituted of wire and perforated zinc, shall have fitted upon it, level with the
extreem edge of the bottom plate, a number of metal boxes of pigeon hole shape,
extending from the extreem edge of the plate to one half the distance to the
central dome, such second cage to have a dome similar to the other cage but the
second.dome to be made large enough to cover and take in the first dome and to be
fitted on the extreem top with a strong hook the purpose of which will appear as
we proceed. This second. cage with the boxes or chambers fitted to it shall
constitute a combination of mudd collectors and baffleing boxes.
When the machine is filled up complete and started in motion the water may be
turned on from the sewage settleing tank immediatly so much of centrifugal force
is attained the filtered water passes with great force and rapidity through the same
filtering media leaving the midd behind in the boxes or chambers, when the mudd
collectors have become sufficiently loaded with mudd or other residuary matter the
water from the settling tank may be stopped for a short time, when the water is
turned off, put the machine on the top speed which in a feew minutes by the extra
centrifugal force attained at a high speed will reduce the mudd to such a state of
dryness as to be available for fuel for generating steam At this stage let a pair of
pulley blocks be suspended over the machine, and by means of the hook on the
dome of the inner cage lift and take the same out, push the dried mud from the
chambers and return the cage to its place in the machine, and proceed as before
and so continue passing by centrifugal force, water through the sand filtering
media, and collecting and disposing of the mudd by the mudd collectors two
sketches No. 1 & 2 illustrate the several parts of my invention A and B point to
the outer and inner wall of the sand chamber. S is the sand chamber X the heads
of the holding dowu bolts D the mudd collectors battleing boxes and driers
combined.
Having now particularly described and ascertained the nature of my said
invention and in what mauner the same is to be performed I would have it
understood that I claim
First. The construction of a complete cavity or sand chamber, so constructed as
to constitute a complete water filter actuated by centrifugal force.
Second. The construction of centrifugal apparatus for collecting and drying the
mudd resulting from the filtration of sewage water or other muddy waters, as
herein before described.
