Improvements in Filters for Wines, Spirits, and other Liquids....
I WILHELM ELZE of Köstritz Thüringen in the Empire of Germany Merchant
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 :-
This invention relates to filters which are especially suitable for filtering wines
and spirits and the object thereof is to enable such filters to be easily cleansed and
the filtering medium to be readily removed from or inserted into the filters.
In the accompanying drawings
Fig. 1 is a front view partly in section of a filter constructed according to this
invention.
Fig. 2 is a partial section of the lower portion of the filter to an enlarged scale.
Fig. 3 is side view of filter.
The same letters denote the same parts in all the figs.
Now according to this invention I construct filters in two parts e aud d of which
e is the receptacle for the liquid to be filtered and d is a receiver for the filtered
liquid.
The receptacle e is made of any suitable size shape and material preferably of
metal in the form of a cylinder as shewn.
c is a cover for the receptacle.
The receptacle e is provided with trunnions ff which rotate in suitable bearings
attached to standards h. One of the trunnions has a hole through it in which may
be inserted a ping to secure the filter cither with the receptacle e uppermost or
with the receiver d uppermost. Near the bottom of the receptacle e is attached
by means of an angle ring (as shewn) a perforated metal plate or wire gauze a.
A similar plate
or gauze bis attached by means of an angle ring to the top of
the receiver d, both plates or gauzes being preferably detachable from the angle
rings. I may for this purpose form keyhole or bayonet slots in the plates or
gauze and secure pins or studs adapted to engage with the said slots to the angle
rings.
To the bottom of the receptacle and to the top of the receiver are secured angle
rings rr and to enable the receiver d to be attached to the receptacle e I provide
bolts i fitted with wing nuts which bolts pass through both angle rings as shewn.
k is a cock to enable the filtered liquid to be drawn off.
To charge the filter it is turned on its axis until the receiver d is at the top aud
maintained in that position by means of the pin g the receiver is then detached
from the receptacle e. The filtering material e preferably cellulose boiled to a
jelly is placed in the space between the plate or gauze a and the bottom of the
receptacle and well pressed down until the said space is full. A hair sieve b' is
then placed on the top of the filtering material and the receiver replaced an india-
rubber or other suitable washer being inserted between the angle rings to form a
joint and the nuts screwed up.
The pin g is then removed and the filter turned until it assumes the position
shewn at Fig. 1 the recptacle e filled with liquid and the cover replaced.
The filter is turned receptacle downwards for cleansing purposes.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performned I declare that what I
claim is :-
1. Filters for wines spirits and other liquids consisting of a receptacle e having a
perforated metal plate or wire gauze a secured therein near the bottom of the said
receptacle and a receiver d detachably connected to the said recptacle the said
receiver having a perforated metal plate or wire gauze b secured to the top thereof
the space between the said plates or gauze being filled with a suitable filtering
material all substantially as herein before specified.
2. The construction of filters for wines spirits and other liquids as shewn by the
accompanying drawings.
Dated this 22nd day of September 1896.
