page_text: I, AUGUSTE EMILE HENRI LOZE of 281 West Derby Road, Liverpool in the
County of Lancaster, Aerated Water Manufacturer, do hereby declare the nature
of this invention to be as follows:-
The objects of this invention are, first, to provide a filtering surface or medium
which shall be highly efficient in preventing microbes, spores, dirt, and other
objectionable organisms, or matters, from passing through, whilst at the same
time little obstruction is presented to the passage of water or other liquid; and
such serface or medium can be easily cleaned when it has become foul; and
second, to so arrange the junction between the ends or sides of the filtering
surface or medium and the supporting structure, that objectionable organisms or
matters shall be prevented from passing between such filtering surface or medium
and the surface of the supporting structure.
For the above purposes, First, I construct a filtering surface or medium of
layers of threads arranged parallel to each other, and supported by a perforated
or permeable plate, tube, or other structure. The threads are formed of fibrous
material such as cotton, wool, and the like, as may be found suitable.
Second, I form the surface of the supporting structure, at or about the sides
or ends of the filtering medium, with corrugations, into which some of the
threads of the filtering medium are firmly laid, thereby preventing the passage
of objectionable organisms or matters between the filtering medium and the
supporting structure.
A convenient form of construction is as follows:-A perforated tube closed at
one end, and provided with corrugations at each end, is covered with layers of
threads of cotton by winding on as on a bobbin or spool, the threads being wound
into the corrugations firmly. The open end of the tube passes through, or is
formed with, a plate which serves as a cover to a container into which the water
or liquid to be filtered passes. The liquid passes through the filtering medium
and out through the open end of the tube, all objectionable organisms or matters
being retained by such filtering medium."
If desired the filtering surface may be coated with asbestos, charcoal, infusorial
earth, or like inorganic substance in a state of minute division; or such materials
or any of them may be added to the water to be filtered whence they will be
deposited on to the filtering surface.

page_text: I AUGUSTE EMILE HENRI LOZE of 281 West Derby Road, Liverpool in the
County of Lancaster, Aerated Water Manufacturer, 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 objects of this invention are, first, to provide a filtering surface or medium
which shall be highly efficient in preventing microbes, spores, dirt, and other
objectionable organisins or matters, from passing through, whilst at the same
time little obstruction is presented to the passage of water or other liquid, and
such surface or medium can be easily cleaned when it has become foul: and,
second, to so arrange the junction between the ends or sides of the filtering
surface or medium and the supporting structure that objectionable organisms or
matters shall be prevented from passing between such filtering surface or medium
and the surface of the supporting structure.
For the above purposes, First, I construct a filtering surface or medium of
layers of threads arranged parallel to each other and supported by a perforated
or permeable plate tube or other structure. The threads are formed of fibrous
material such as cotton, wool, fine metallic wire and the like as may be found
suitable.
"
Second. I form the surface of the supporting structure at or about the sides or
ends of the filtering medium with corrugations into which some of the threads of
the filtering medium are firmly laid thereby preventing the passage of objection-
able organisms or matters between the filtering medium and the supporting
structure.
If desired the filtering surface may be coated with asbestos, charcoal, infusorial
earth, or like inorganic substance in a state of minute division, or such materials
or any of them may be added to the water to be filtered, whence they will be
deposited on to the filtering surface.
Fig. 1 on the accompanying sheet of drawings is a vertical section of a filter
constructed according to my invention, and Fig. 2 is a sectional view showing
the filter bobbin in elevation. a is a perforated or permeable tube closed at one
end and provided with corrugations at each end. The perforated tube is covered
with layers of threads of cotton or other suitable material c. forming the filtering
medium or surface, by winding such threads on in a similar manner to the thread
on a bobbin or spool, the consecutive turns of each layer of thread being parallel
or approximately parallel to each other. The thread is firmly wound into the
corrugations at each end of the tube a, so as to prevent objectionable matters
passing round the ends of the filtering surface. The thread may be wound in
various ways on to the tube a one thread wound backwards and forwards along
the tube, or several threads in the form of a narrow tape wound backwards and
forwards along the tube may be used; or a number of threads together equal in
width to the whole length of the tube may be used: and also the successive turns
of thread may either touch each other or there may be interstices which are
covered by the next layer of thread. The open end of the tube a is formed with
or secured to a plate d, which serves as a cover to a container e into which the
water or liquid to be filtered passes through the opening f. The water or liquid
passes from the container through the layers of thread c which form the filtering
medium, and out through the passage purified, all objectionable organisms or
matters being retained by the filtering medium. The layers of thread may be
coated with inorganic substances in the form of powder in any usual way if
desired.

page_text: Fig. 3 is a view in elevation of a tube a, similar to that described in Figs. 1
and 2. Here the parallel threads of one layer are crossed at a considerable angle
by the threads of the contiguous layers.
Fig. 4 is a sectional view of a modification under my invention, a are per-
forated plates preferably formed in one piece with a central tube g. and passages a¹.
The layers of threads c. are wound in between the plates a. and into the
corrugations b. in a similar way to that described under Figs. 1 and 2, and a
similar container is used from which the water or liquid passes through the
perforations in the top plate through the layers of threads, through the perforations
in the lower plate and out through the passages a' and central tube g.
In all the above cases the course of the water or liquid may if desired be the
reverse of that described.
Fig. 5 is a perspective view of another modification under my invention, and
Fig. 6 is a perspective view of the perforated supporting box in Fig. 5.
a. is a
box with perforated surfaces, c. c care layers of parallel threads, the threads of
one layer or set of layers c being crossed at right angles by the threads of the
other layers-cl-2-as-shown. The course of the water is through the layers of
thread to the interior of the box and out through the pipes g.
I do not confine myself to the particular arrangements shown as many modifica-
tions may be made without departing from my invertion and the threads may
be of any material which may be found suitable for the purpose.
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. The formation of a filtering surface or medium by means of layers of
parallel threads or approximately parallel threads supported by a perforated or
permeable plate, tube, or other structure substantially as and for the purpose set
forth.
Second. Forming the junctions between the sides or ends of filtering mediums
or surfaces, having parallel threads, and the supporting structure by means of
corrugations or the like into which threads are firmly wound substantially as and
for the purpose set forth.
Dated this Sixth day of October 1897.
