page_text: I ALOYSIUS FRANCIS VUYLSTEKE, Merchant of Tournai (Belgium) do hereby
declare the nature of this invention to be as follows:-
The object of this invention is:—
First. To fit the centre holes of the plates of Filter Presses with screw collars
the flanges of which fasten the cloths rigidly at that part to the plates.
Secondly. To make the plates of Filter Presses hollow or of less thickness in the
body than at the edges and fluting or grooving said plates according to any
convenient or desired formation said flutings or groovings terminating with
apertures at the end of each groove leading into a passage common to all the
grooves of the plate.
Thirdly. To making apertures at one or at more than one of the upper corners
of each plate, if said plates be of square or equivalent shape, with holes leading
therefrom and of such a shape that metal eyelets with which the corners of the
cloths are provided may lodge therein leaving the passage clear. These apertures
in the several plates coincide and permit of the plates to be easily cleansed by
steam or a rod brush, the end plates, or the frame being provided with screw plugs
to close the passage. This is also the case with the lower channel at one portion
of which a draw off tap is provided for the discharge of the filtered liquor. The
end aperture can be provided with a valve or a separate valve can be fitted to
allow the air to escape as the pumping progresses and can then be closed. The
machine is provided with a pump worked by a weighted handle capable of being
shifted on supports to be worked from the right or from the left hand as desired.
The pump is provided with an air chamber the shell of which is in two parts
screwed together capable of being disconnected for cleaning purposes and a tap is
provided for emptying the pump and the main pipe.
Fourthly. To fitting a hinged shank or rod to the end plate so that said rod
when raised fills up the space or nearly so between the outer plate and the end
frame so that a short screw can be used for putting all the plates into contact.
Among the advantages derived from the use of my invention are:-
1. A quick system of opening and closing the press,

page_text: 2. A novel system of drawing out the confined air usually imprisioned in the
upper part.
3. A regular and easy system of drawing the liquid (filtered) out of the
chambers.
4. A novel system of cleaning the plates by steam and killing all the bad
ferments that may be left in the press said cleaning being done without taking off
the cloths.
5. An easy and secure manner of fixing the cloths at the entrance of the liquid
in each chamber.

page_text: I ALOYSIUS FRANCIS VUYLSTEKE Merchant, of Tournai (Belgium), do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
The object of this invention is
First. To fit the centre holes of the plates of Filter Presses with screw collars
the flanges of which fasten the cloths rigidly at that part to the plates.
Secondly. To make the plates of Filter Presses hollow or of less thickness in the
body than at the edges and fluting or grooving said plates according to any
convenient or desired formation said flutings or groovings terminating with
apertures at the end of each groove leading into a passage common to all the
grooves of the plate.
Thirdly. To, making apertures at one or at more than one of the upper corners
of each plate if said plates be of square or equivalent shape with holes leading
therefrom and of such a shape that metal eyelets with which the corners of the
cloths are provided may lodge therein leaving the passage clear. These apertures
in the several plates coincide and permit of the plates to be easily cleansed by steam
or a rod brush, the end plates or the frame being provided with screw plugs to close
the passage. This is also the case with the lower channel at one portion of which
a draw off tap is provided for the discharge of the filtered liquor. The end aperture
can be provided with a valve or a separate valve can be fitted to allow the air to
escape as the pumping progresses and can then be closed. The machine is provided
with a pump worked by a weighted handle capable of being shifted on supports to
be worked from the right or from the left hand as desired. The pump is provided
with an air chamber the shell of which is in two parts screwed together capable of
being disconnected for cleaning purposes and a tap is provided for emptying the
pump and the main pipe.
Fourthly. To fitting a hinged shank or rod to the end plate so that said rod
when raised fills up the space, or nearly so, between the outer plate and the end
frame so that a short screw can be used for putting all the plates into contact.
Among the advantages derived from the use of my invention are
1. A quick system of opening and closing the press.
2. A novel system of drawing out the confined air usually imprisoned in the
upper part.
3. A regular and easy system of drawing the liquid (filtered) out of the
chambers.
4. A novel system of cleaning the plates by steam and killing all the bad
ferments that may be left in the press said cleaning being done without taking off
the cloths.
5. An easy and secure manner of fixing the cloths at the entrance of the liquid
in each chamber.
This invention will be understood by reference to the annexed drawings in which
ALL

page_text: is covered with cloths of any suitable material having a drainage hole in the centre
which corresponds with an aperture B in the centre of the plate A, the cloth being
firmly fixed in position at the point by a screwed eyelet C. The plates A, A, are
arranged between two end plates or frames D, D¹, which are connected together by
two rods or bars E, E¹, on or between which the plates A, A, move when pressure
is put upon them by the screw F acting upon a pressure plate G through the
medium of a hinge shank H.
Figure 2 is an elevation of one of the plates A and shows also a vertical section
through the centre of plate on line a, b. The plate A is made with grooves or
flutings I, I with holes J at the end of each groove. The holes J communicate
with a canal or pipe K from which the liquid can be run out by the tap L. The
canal or pipe K has a screw plug M, M¹, at each end which may be unscrewed for
the admission of steam or a brush when it is desired to clean said pipe.
Figure 3 is a part sectional plan of the filter press and Figure 4 an end elevation.
N is a main or steam or water pipe in the corner of each plate A with which it
communicates by a hole P. Steam is admitted to the pipe N from the steam and
water inlet by the screw valve R for the purpose of thoroughly cleaning the
filter and to kill any germ of bad ferment which might be lodged inside.
'
Before beginning to fill the press with liquid to be filtered the screw valve R is
slightly opened so as to allow the escape of air as the liquid rises, the valve R
being screwed close as soon as the liquid begins to pass it. By this means no air
spaces exist between the plates A A. and consequently no filtering surface is lost.
S is the pump for forcing the liquid into the filter press through the main T
which is provided with an air chest U preferably constructed of two parts V, V₁
screwed together.
The pump S is worked by a hand lever W balanced by a weight X and capable
of being worked on either side of the pump S.
Y is a tap for the purpose of emptying the pump S, air chest U and main T.
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. Fitting the centre holes of the plates of Filter Presses with screw collars
or eyelets C for the purpose of rigidly fastening the cloths at that part to the
plates A, A.
2. Making the plates A of less thickness in the body than at the edges, and
grooving or fluting said plates, the grooves leading into a passage K common to all
of them, substantially as described for the purpose set forth.
3. Making apertures to form portions of a pipe or main N at one or more than
one of the upper corners of each plate A for the purpose hereinbefore set forth.
4. The construction of a pump S provided with an air chamber or chest U
the shell of which is in two parts screwed together for the purpose herein before
described.
5. The arrangement of a hinged shank H attached to the end plate of a filter
press as herein before described and shown on the annexed drawings.
6. The combination of the several appliances or improvements hereinbefore
described in or to one machine.
