PROVISIONAL SPECIFICATION.
Improvements in Filter Funnels.
I, JOHN REYNOLDS MURRAY, of 11, Mill Street, Hanley, in the County of
Stafford, Sheet Metal Worker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in combined filters and funnels for filtering
and clearing ale, porter, cider, and other liquors at the same time that such liquors
are being put into the barrels. The invention consists of a funnel with an
elongated perforated filling tube, and in the body of the funnel is a detachable
sieve or filter covered by a perforated or grid-like cover and moveable cap, so that
the several parts can be separated for cleaning or washing purposes.
According to this invention, I employ a funnel with an elongated filling tube, the
bottom or end of which is closed, but the lower portion of the tube is perforated for
the passage of the liquid. On the underside of the body of the funnel is a projection
or support which rests on the barrel when the funnel is in position. Inside and at the
bottom of the funnel is a perforated or grid-like cylindrical chamber, and inside
this chamber is a moveable filter of wire, silk gauze, or of sponge, flannel, or other
like material readily cleansed by washing. Over the filter or sieve is a cap or cover
connected to a pipe or tube extending to a level with the top of the funnel, by means
of which the cap or cover can be raised or moved.
When the filter and funnel are placed in position through the vent hole in bung
of the barrel, the liquor is placed in the body of the funnel, and passes through the
filter down the filling tube by way of the perforations to the interior of the barrel.
The settlings collect on the cap or cover of the filter and in the angle at the bottom
of the funnel outside the grid chamber, and the liquor is further cleared by passing
through the inner filter.
Date this 22nd day of July 1896.

I, JOHN REYNOLDS MURRAY of 11 Mill Street, Hanley, in the County of
Stafford, Sheet Metal Worker, do bereby 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 improvements in combined filters and funnels for filtering
and clearing ale, porter, cider, and other liquors at the same time that such liquors are
being put into the barrels. The invention consists of a funnel with an elongated
perforated filling tube, and in the body of the funnel is a detachable sieve or filter

page_text: covered by a perforated or grid-like cover and moveable cap, so that the several parts
can be separated for cleaning or washing purposes.
Such being the nature and object of my said invention, the following is a complete
description of same, reference being had to the annexed drawings, in which :-
Fig. 1 is a sectional elevation of the improved filter funnel.
Figs. 2, 3, and 4 are parts shewn separately.
According to this invention, the tube 1 is made sufficiently small to admit it
to go through the vent hole in the bung of the barrel, and the bottom of which
is finely perforated, 2, so that when it dips into the liquor already in the barrel,
the flow is so gradual that it will not disturb the contents and can be separated
at from the body of the funnel 5 for washing purposes, or for using on an open
vessel. In the inside bottom is a cylinder 6 covered over with a moveable grid 7
made of very fine gauze wire. The silk lawn 8 is placed on the top of the
cylinder 6 and the moveable grid 7 is placed on and pressed down, which holds the silk
lawn tight. Inside the cylinder is the sponge chamber which keeps the sponge 91
in position, so when the liquor is placed in the body of the filter it passes through
three refinings 7, 8, 9 by the one action, down the filling tube by way of the
perforations, to the interior of the barrel. All the several parts can be separated for
cleaning and washing purposes, or for using separately. When the liquor is very
dull and cloudy the cap 10 or overall may be used over the gauze grid before putting
in the liquor. When the liquor is sufficiently settled, raise the cap gradually, it
will bring with it a good portion of the settlings, the other settlings will remain
in the space 11 at the bottom of the filter round the outside of the cylinder, the
inner portion 12 of which forms a foot or rest for the apparatus in position on the
barrel.
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 construction, arrangement, and combination of parts constituting the
improvements in filter funnels, substantially as herein described and illustrated by
drawings annexed.
