IMPROVEMENTS IN THE MODE OF APPLYING THE FILTERING CLOTHS TO FILTER PRESSES
Year: 1884

page_text: I JAMES JOHN MUSTO of 21 Clinton Road, Mile End in the county of Middlesex
Engineer do hereby declare the nature of the said Invention for IMPROVEMENTS
IN THE MODE OF APPLYING THE FILTERING CLOTHS TO FILTER PRESSES to be as
follows:-
Whereas in the ordinary methods of applying or changing the cloths used for
the plates of filter presses it has been found that much time is lost when a large
number of plates have to be prepared and also that unnecessary wear is caused to
the cloths.
Now my invention is intended to simplify the manner in which such filtering
cloths are arranged in their positions on the filtering plates whereby they may be
at once applied or changed without loss of time and with less wear to the cloths.
And my invention consists in making the cloth in such a form as to be capable
of adjustment preferably over the top edge of the filtering plate and so as to hang
down on each side. A hole is made in each side of the cloth to correspond with
the aperture in the filtering area of the filter plate, such aperture in the said
plate having a raised rim round it to hold the cloth in its position as required
by adjusting the cloth round the raised rims on the filtering plates by means of the
holes made on either side of such cloth.
:
The said rim may either be made flush with the outer rim of the plate with
cavities for the liquor to be expressed to pass through or of less depth than the said
outer rim for the same purpose.
The said rim is made either parallel or tapered in order that the cloth may fit
tightly on it.
When the cloths are arranged on the plates and these are placed in their positions
in the filter press, the tightening up of the press will cause the cloths to be kept
stretched over the plates in the manner required and the two ends of the
press and the intermediate plates will hold the edge of the cloths in the manner
desired.

I JAMES JOHN MUSTO of 21 Clinton Road Mile End in the County of Middlesex,
Engineer do hereby declare the nature of my invention for "IMPROVEMENTS IN
and in
THE MODE OF APPLYING THE FILTERING CLOTHS TO FILTER PRESSES
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Whereas in the ordinary methods of applying or changing the cloths used for
the plates of filter presses it has been found that much time is lost when a large
number of plates have to be prepared and also that unnecessary wear is caused
to the cloths.
Now my invention is intended to simplify the manner in which such filtering
cloths are arranged in their positions on the filtering plates whereby they may be
at once applied or changed without loss of time and with less wear to the cloths.
And my invention consists in making the cloth in such a form as to be capable
of adjustment preferably over the top edge of the filtering plate and so as to hang
down on each side. A hole is made in each side of the cloth to correspond with
the aperture in the filtering area of the filter plate, such aperture in the said
plate having a raised rim round it to hold the cloth in its position as required
by adjusting the cloth round the raised rims on the filtering plates by means of the
holes made on either side of such cloth.
The said rin may either be made flush with the outer rim of the plate with
cavities for the liquor to be expressed to pass through, or of less depth than.the-
said outer rim for the same purpose.
The said rim is made either parallel or tapered in order that the cloth may fit
tightly on it.
When the cloths are arranged on the plates and these are placed in their positions
in the filter press, the tightening up of the press will cause the cloths to be kept
stretched over the plates in the manner required and the two ends of the
press and the intermediate plates will hold the edges of the cloths in the manner
desired.
In order that my invention may be fully understood I will proceed to describe
it more particularly by the aid of the accompanying drawings in which are shewn
the parts above referred to. In these several figures the same letters of reference
indicate corresponding parts.
DESCRIPTION OF THE DRAWINGS.

page_text: The cloth B is hung preferably over the top edge of the plate A as required,
being further adjusted by contact with the other plates and inside end surfaces of
the press when this is tightened up.
The said raised rim C may either be made flush with the outer rim of the plate E
with cavities for the expressed liquor to pass through as shewn in fig: 3 or of less
depth than the said outer rim E as shewn in fig: 4.
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
The method of making and applying a filtering cloth in such a form as to be
readily adjusted on a filtering plate such plate having a raised rim formed round
an aperture in the filtering area of the same substantially as and for the purpose
hereinbefore described.
Dated this 27th day of January 1885.
