AN IMPROVED MODE OR METHOD OF ADJUSTING THE FILTERING CLOTHS USED IN 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 AN IMPROVED
MODE OR METHOD OF ADJUSTING THE FILTERING CLOTHS USED IN FILTER PRESSES
to be as follows:-
My invention relates to the adjustment of filtering cloths which are made so as
to hang over the filter plates and fit round the raised rim of the aperture of such
plates, being further kept in their required position by the two ends of the press
and intermediate plates when these are arranged and tightened up.
In some cases it has been found advisable to provide a means whereby the tension
of such cloths as above referred to may be increased, and for this purpose I provide
the following arrangement.
On the upper rim of the filter plate I cast two or more lugs placed horizontally
having a hole made through each of them to admit of two or more long pins passing
through such holes. These pins are fixed to a bar which extends in a parallel
direction along the top of the plate. Springs are provided so as to press the bar
upwards, and may be of a spiral form and coiled round the pins fixed to the bar,
or they may be in the form of plate springs fixed between the rim and the bar.
The cloth is hung over the said bar and the holes in such cloth are arranged
round the raised edge of the aperture in the filter plate on either side, this being
done it will be seen that the upward pressure of the spring between the bar and
the edge of the filter plate, will cause the cloth to be stretched in the manner
required.
By this means the desired increase in the tension of the cloths is obtained, and
they are further held in their position when the press is tightened up.

and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-

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
represented the parts above referred to.
DESCRIPTION OF THE DRAWINGS.
In these two figures the same letters of reference indicate corresponding parts.
Fig 1 is an elevation of a filter plate with part of a filtering cloth upon it and
fitted with the box and plate unsin
In these two figures the same letters of reference indicate corresponding parts.
Fig 1 is an elevation of a filter plate with part of a filtering cloth upon it and
fitted with the bar and plate springs
Fig 2 is a similar view to Fig 1 but without the filtering cloth and with spiral
springs fitted at each end of the bar.
A is the filtering plate B part of the filtering cloth only shewn as covering half
the side of the plate C is the raised rim for holding the cloth D the bar extending
horizontally along the top of the plate and held by means of pins I screwed into
lugs H Springs F or G are provided so as to press the bar upwards thereby

in place by the contact of the rims of the plates E and the sides of the press when
this is tightened up.
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 adaptation and application to filter plates of a bar with a spring or springs
for the purpose of increasing or regulating the tension of the filtering cloths as
required in the manner substantially as herein before described.
