PROVISIONAL SPECIFICATION..
Improvements in Filters or Tap Appendages for Beer and other
Liquids.
I, ROBERT STEWART MCMAHON, of 33, Botanic Road, in the City of Liverpool,
Gentleman, do hereby declare the nature of this invention to be as follows-
This invention has for its object a filter or tap appendage whereby liquids, more,
especially beer, can be filtered as they proceed from the tap. Hitherto in tilting
barrels, in order to pour out the beer, the sediment is apt to get locked up with the
beer and thus about a quarter of the beer in each barrel is practically wasted or muddy.
Now the object of my invention is to extract this mud so that the entire contents
of the barrel can be used. Further, when the barrel is nearly spent, the beer is apt
to be somewhat flat: I so arrange my invention that it shall put an artificial edge
on this beer.
My apparatus consists of five parts
Firstly, a nozzle having a number of finely perforated holes; secondly a body
screwing into this nozzle or if desirable screwing over this nozzle. These two can be
made in one part, I prefer however for convenience having them in two pieces.
Thirdly, a cap with milled, edge, or other arrangement for screwing it, screwed onto.
the body. This cap has a projecting flange and between this flange and the body
the flange of an indiarubber flanged cone is tightly compressed. The flange of the
cap protects to some extent the flanged cone. Lastly, the inside of the body and the
nozzle I pack with sponge or other suitable filtering material.
The mode of action is as follows:-
When all is in position, the cone is slipped onto the end of the tap and the
pressure of the liquid and the elasticity of the indiarubber keep the cone duly
squeezed on the tap in the manner well known, these cones being continually used
for attaching hosepipe and the like to taps. The tap is now turned, the liquor
passes through the sponge leaving all coarse solid matter behind and passes out in
a series of fine jets into the glass. These draw a large quantity of air with them
and thus form a very large head on the beer.

ROBERT STEWART MCMAHON, of 33, Botanic Road, in the City of Liverpool,
Gentleman, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement :-
This invention has for its object a filter or tap appendages whereby liquids, more
especially beer, can be filtered as they proceed from the tap. Hitherto in tilting
barrels, in order to pour out the beer, the sediment is apt to get locked up with the
beer and thus about a quarter of the beer in each barrel is practically wasted or

Now the object of my invention is to extract this mud so that the entire contents
of the barrel can be used. Further when the barrel is nearly spent, the beer is apt
to be somewhat flat; I so arrange my invention that it shall put an artificial edge

My apparatus consists of five parts:-
Firstly, a nozzle having a number of finely perforated holes; secondly a body
screwing into this nozzle or if desirable screwing over this nozzle. These two can
be made in one part, I prefer however for convenience having them in two pieces.
Thirdly a cap with milled, edge, or other arrangement for screwing it, screwed onto
the body. This cap has a projecting flange and between this flange and the body
the flange of an indiarubber flanged cone is slightly compressed. The flange of the
cap protects to some extent the flanged cone. Lastly the inside of the body and
the nozzle I pack with loofah.
The mode of action is as follows:-
When all is in position, the cone is slipped onto the end of the tap and the
pressure of the liquid and the elasticity of the indiarubber keep the cone duly squeezed
on the tap in the manner well known, these cones being continually used for attach-
ing hosepipe and the like to taps. The tap is now turned, the liquor passes through
the loofah leaving all coarse solid matter behind and passes out in a series of fine
jets into the glass. These draw a large quantity of air with them and thus form a
very large head on the beer.
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
