Improvements in Filters for Malt Beverages.
I, WILLIAM HUMPHREY WHEATLEY, of the Firm of Wheatley and Mackenzie,
Engineers and Patent Agents, of 40, Chancery Lane, in the County of London,
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 invention has relation to a novel form of filter for malt beverages; and the
object is to provide a simple, practical and economical filter of this class.
To this end the invention consists in certain features of construction and com-
bination of parts which will be hereinafter fully set forth.
In the accompanying drawings:-
Figure 1 is a perspective view of my improved filter.
Figure 2 is a transverse section of the same.
Figure 3 is a detail perspective view of one of the intermediate filter frames
or pans.
Figure 4 is a similar view of one of the diaphragms.
Figure 5 is a similar view of one of the filtering cloths.
1 represents the base, which is provided with a series of supporting casters
for conveniently moving the filter about, and with a series of integral vertically
slotted ears 2-2, and a pair of diametrically disposed ears 3-4, which are also
vertically slotted. The ear 3 is formed with a passageway 5, which communicates
with an annular pocket or recess 6 formed in the upper face of said base. A
foraminous diaphragm 7 is provided with annular mutilated flanges 8 and 9,
which form supports upon which it rests in the pockets. 10, 11 and 12 represent
a series of filtering disks, which rest upon the diaphragm and form the filtering
medium. These disks are made of any well known porous filtering material,
or of felt, or any textile fabric, and are of different degrees of texture or porosity,
to accomplish the end in view. When made of textile material, they will serve
for packing between the sections or pans.
These disks are also provided with orifices 13-13, which form a passage for
the liquid between the intervening sections or pans. 14 represents one of these
sections or pans, of which there may be an indefinite number to correspond to the
capacity of the filter, and these sections or pans are formed with a pair of
oppositely disposed integral lugs 15 and 16 provided with communicating
passages 17 and 18, the latter 18, forming the inlet passage to the filter, and the
former, 17, forming the outlet passage therefrom. Each section or pan is provided
with an annular pocket or recess 19' on its upper face, and a corresponding
pocket or recess 20 on its under or lower face, the passageway 17 com-
municating with the pocket 19 through the short duct 19', and the passageway
18 communicating with the recess or pocket 20 through the short duct 20¹.

page_text: A foraminous diaphragm 71, corresponding to the diaphragm 7, is located in the
pocket 19 to form a support for the filtering cloths 10-11 and 121. 21 represents
the top section, which is provided with the vertically slotted cars 21-21, which are
aligned with the corresponding ears on the base section, to receive the bolts 22–22
which bind the top, base and intermediate sections firmly together. The ears 31-41
are also provided with passageways 23 and 24, the former constituting the outlet
and the latter the inlet passage, and the course of the liquid may be traced by the
arrows in Figure 2, any given particle of the liquid having to pass only through
the single set of filtering disks between its inflow and outflow.
Although we have specifically described a construction and relative arrangement
of the several elements of the invention, we do not desire to be confined to the
same, as such changes or modifications may be made as clearly fall within the
scope of the invention, without departing from the spirit thereof.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
A filter comprising top and bottom sections and a series of intermediate
sections having communicating inlet and outlet passages, a foraminous diaphragm.
interposed between said sections, and filtering media supported by said diaphragms
and consisting of sections of filtering material of different degrees of porosity,
substantially as set forth.
Dated this 26th day of July 1898.
