PROVISIONAL SPECIFICATION.
Improved Tap Filter.
I, EDWIN CHARLES HIRONS of the Filter & Art Metal Advertising Works
86 Angelina Street Highgate Birmingham in the County of Warwick Manufacturer
do hereby declare the nature of my said invention to be as follows:-
My invention has for its object an improved reversable filter for taps which I call the
Hygia and by which I obtain an improved appearance as well as a better distribution
of the water through the filtering substance and increased facility for the ready & easy
cleansing of the interior.
In carrying my invention into effect I form the outside casing of a globe or oval
shape having flutes running in length from the one opening to the other and this
outer casing I fill with carbon & lime stone and provide it at one mouth with an
internal perforated projection which is fixed to the outer casing and also forms a rim
which projects some distance outside which rim has a screw thread on the outside for
the reception of the screw cap & rubber for attaching to the tap and is also tapped on
the inside for the reception of the screwed outlet nose. The other mouth of the outer
casing is also formed with a perforated projection inside but in this case the projection
instead of being fixed to the outer casing is screwed in so as to allow of being taken
out for cleansing and this removable piece is also provided with the projecting rim
outside having the external screw for the reception of the screw cap and the internal
screw for the reception of the screwed outlet nose as at the other end.
Dated 25th day of October 1889.

COMPLETE SPECIFICATION.
Improved Tap Filter.
1 EDWIN CHARLES HIRONS of the Filter and Art Metal Advertising Works
86 Angelina Street Highgate Birmingham in the County of Warwick Manufacturer
do hereby declare the nature of this invention and in what manner the same is to be
performned, to be particularly described and ascertained in and by the following
statement:-
My invention has for its object an improved reversible filter for taps by which 1
obtain an improved appearance as well as a better distribution of the water through
the filtering substance and increased facility for the ready and easy cleansing of the
interior.
In carrying my invention into effect I form the outside casing of a globe or oval
shape and having flutes running in length from the one opening into the other and
this outer casing I fill with carbon and limestone and provide it at one month with an
internal perforated projection which is fixed to the outer casing and also forms a rim
which projects some distance outside which rim has a screw thread on the outside for
the reception of the screw cap and rubber for attaching to the tap and is also tapped
on the inside for the reception of the screwed outlet nose.
The other mouth of the outer casing is also formed with a perforated pro-
jection inside but in this case the projection instead of being fixed to the outer casing
is screwed into the casing so as to allow of being taken out for cleansing and this
removable piece is also provided with the projecting rim outside having the external
screw for the reception of the screw cap and the internal screw for the reception of
the screwed outlet nose as at the other end.
In order that my invention may be clearly understood and more easily carried into

page_text: practice I have appended hereunto one sheet of drawings upon which I have fully
illustrated the nature of my said invention.
Figure is a vertical section through the filter attached to the mouth of tap .r.
Figure 2 is an elevation of same also attached to the mouth of a tap .r.
Referring to the drawings my filter consists of the fluted casing a baving the
internal projection which is fixed to the casing a at the one mouth of the filter and
the similar internal projection d which is screwed into the casing a at the reverse
mouth of the filter both the projections and d having the perforated ends and d
through which the water is distributed into the filtering substance e as shown by thick
dotted lines. The internal projections at both ends are also extended outside the
casing a to form external rims 62 and d2 upon which the cap f is screwed which cap
contains the india rubber y for attaching to the tap and for receiving the nozzle h at
either end.
It will thus be seen that by means of the internal projections and I gain
improved distribution of the water through the filtering substance e and by the
removable screw mouth d I am enabled to gain easy access to the filtering substance
for cleansing while an improved appearance and better distribution of the water is
obtained by the fluted globe shape of the filter.
Having now particularly ascertained the nature of my said invention and in what
manner the same is to be performed I declare that what I claim is-
First. An improved reversible filter for taps consisting of the fluted casing a and
provided with the internal perforated projections band d substantially as and for the
purpose herein described and shewn.
Second. An improved reversible filter for taps having the removable screw mouth d
substantially as and for the purpose herein set forth and shewn.
Third. An improved reversible filter for taps substantially as and for the purpose
herein set forth and shewn upon the accompanying drawing.
Dated this 5th day of April 1890.
