L, LOUIS GISMONDI of Marseilles, in the Republic of France, Manufacturer, do
hereby declare the nature of my said invention to be as follows :-
1-
This invention relates to filter presses and more especially to such as are used for
expressing oil from material containing same.
The improvements consist in cortain apparatus hereinafter described for retaining
the material in a simple press. On a suitable corrugated bed plate is laid a perforated
plate and over the same preferably a wash leather or other suitable strainer, around
the plate are walls extensible in perpendicular direction formed of a number of con-
centric rings of circular or other shape capable of sliding within one another and
prevented from separation by suitable overlapping flanges. The lowermost ring is
held down upon its bed plate and the uppermost ring may be supported in its most
extended height by rods catching into a groove therein. The apparatus being extended
a funnel or temporary cylinder is placed in a groove in the uppermost ring and the
device filled with material to be pressed, the funnel or cylinder is then removed and
a corresponding pair of perforated and corrugated plates with strainer, or a plain
plate inserted in its place, the rods or lifts are unfastened and the material pressed
between the plates the extended walls collapsing telescopically as the plates approach
each other.
To raise the walls evenly, rods connected to a plate operated by a screw spindle
are hooked at convenient distances around the rim of the uppermost plate and are
raised equally by the spindle.

page_text: Improvements in or relating to Filter Presses.
I LOUIS GISMONDI of Marseilles in the Republic of France, Manufacturer do
hereby declaro 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 :-
This invention relates to filter presses and more especially to such as are used for
pressing oil from material containing the same.
Reference being made to the accompanying drawings.
Fig. 1 is a cross section and Fig. 2a side view of part of the improved apparatus.
Fig. 3 is a plan view thereof. Fig. 4 is a vertical section of the improved
press.
Figs. 5 and 6 are sectional detail views.
The invention essentially consists in placing above a suitable strainer a collapsible
telescopic receiver, certain other improvements are also made in the construction of
various parts.
The telescopic receiver consists of two or more frames one of which C, is inclined
at its superior edge, the other E is bevelled inwards and vertically movable in the
first.
On the lower plate K of a press is arranged a fluted plate A and above the latter a
perforated plate B. (Fig. 1) to facilitate the flowing of the oil. Over these plates are
placed the frames C and E.
The inferior frame C as well as the perforated plate B fit into the fluted plate A.
On the frame Care provided hinged plates D D serving to support the frame E when
extended upward and ready to receive the load. The superior frame E carries channels
of triangular section into which the hinged plates D engage when the apparatus is
extended as aforesaid. 1 prefer to make the frames CE of the shape shown in the
drawing and arrange the said channels and hinged plates at the four angles of the
frames.
Above the frame E is arranged a movable frame J employed for the filling of the
apparatus. Before introducing the stuff into apparatus another plate or cloth F of
wove horsehair or other suitable material is placed over the plate B.
This plate or cloth F prevents the mass from choking the small holes in the perforated
plate and so facilitates the flowing of the oil.
The press is completed by means of a receiver G replacing and forming the cover
plate of the press. This receiver is provided with two sliding plates; the upper one H
of these being rather thin and destined simply to cut off the supply of the material
into the receiver, the second or lower plate I is much stronger and while movable to
allow of the introduction of the mass into the apparatus forms the floor of the receiver G
and the upper plate of the press.
The mass is introduced by any suitable means into the receiver G the slide plates H
and I of which are closed. When the quantity of the mass on the plate His suffi-
cient, the said plate is opened and the mass falls into the inferior space of the receiver

page_text: and the plate H is closed. The second plate I is then opened and the measured mass
falls into the apparatus. After having spread the paste equally, closed the lower plate I.
and opened the upper plate H. the communication pipo to the ram is opened. The plate K
ascends lifting the loaded apparatus, and presses the contents against the receiver G
performing the functions of the upper plate.
In order to obtain the necessary preliminary pressure without causing a flowing out
of the oil it is sufficient that the apparatus ascends until the piston G is immerged in
the said apparatus to the whole height of the frame J.
The communication pipe to the ram is then closed and the outlet pipe opened, the
apparatus descends and the frame J may be lifted off; the hinged plates are turned
down and the telescopic receiver with the platos thereunder are removed from the base
plate of the press to a stack of similarly filled receivers for operation in a final press.
Other similar apparatus as in Figs. 1, 2 and 3, constructed in the same manner as the
first are similarly filled and placed above the first so that the fluted plate A of the
second fits upon the frame of the first apparatus and forms a cover thereto.
Repeating the same operation with similar apparatus, a stack of a certain height is
thus built up having undergone the action of a preparative press and ready to receivo
that of the extraction press.
After the compressing of this stack and the extraction of the oil each of the apparatus
are dismembered and the oil cakes therein may be taken out.
Another manner of operation economizing time is as follows: As the apparatus
are taken from the first press they are placed on a trolly or carriage and taken to a
stack of a certain height near to the extruction press. Each finally pressed apparatus
when taken away is replaced by another one. In this manner the extraction press is
kept in continual work. With regard to the apparatus G performing the function of a
hopper, of a paste meter, of a paste distributor and of a piston the function of this
apparatus is continued as long as the press operates the superior space of the receiver G
is gradually filled the plate H being closed.
The latter being opened the lower space is filled and it is sufficient to open the
plate I in order to instantly load the apparatus.
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. The combination of a telescopic receiver with a strainer floor thereto for the
purpose sot forth.
2. The combination of a fluted plate a perforated plate thereon, a horse hair or
equivalent strainer on said perforated plate and a telescopic wall about said plates with
means for supporting same substantially as set forili.
3. The combination in a press of a receiver G with sliding plates H and I sub-
stantially as and for the purpose set forth.
4. In apparatus for extracting oil etc., the combination of a press having a receiver (+
substantially as set forth a series of telescopic receivers having strainer floors sub-
stantially as set forth and a press adapted to hold and compress said telescopic
receivers for the purpose described.
