Improvements in Water Filters.
I, ROBERT GOUGH of 31 Walpole Street, Chelsea in the County of Middlesex,
Engineers Clerk, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improvement in the construction of water filters, attached
to the supply pipe of any domestic establishment, for the purpose of providing
a running supply of purified or defecated water, for drinking or any other mode
of consumption.
The object of my invention, is to attach this said Filter either near or above
the position of any ordinary bib tap or valve where it is usually situated for the
purpose of obtaining water from the supply of a cistern; by first removing this
aforesaid bib tap or valve, and connecting the Filter by the fittings supplied and in
connection with my invention; so that when my invention is duly fixed to the supply.
pipe, I can cause a running supply of purified water to run' continuously.
My invention is constructed in a cylindrical form of glazed earthenware or any
other material with two openings at the bottom, and a flanged top with lugs or cars,
for the purpose of attaching the cover by two screws being passed through holes in
the lugs or ears, and the cover screwed down by fly nuts. The top of the glazed
earthenware cylinder has an opening provided a short distance downwards, with a
sunk well running round the circumference of the cylinder with a flanged collar
projecting upwards; a bib piece of metal tube is fixed above the well for the purified
water to flow outwards.
At the bottom of the cylinder is situated in the centre an opening to connect the supply,
and is formed with a flanged bush piece with a male thread outside, with leather washers,
passing through the hole, and a metal cap with perforations, screwed on to the bush,
to hold it in its position. A perforated metal ring slides over the perforations in the
aforesaid cap,
to prevent any of the loose charcoal passing down into any of the
fittings.
A metal cap and lining is fixed to the other opening at the bottom, to enable
any person to remove the used up charcoal by unscrewing the cap, and working the
charcoal from the top of the filter with the flow of water from the bottom; and by
this means the charcoal will pass out, the cap is then replaced, and the filter rechargeil
with charcoal. On the inner flange above the well is placed a ring of india rubber,
and a block of carbon inserted in an earthenware ring the same size as the flange of
the well; and when the outer cover is screwed down, a small plug is also screwed
down from the centre of the cover on to the top of the carbon to secure the
carbon in its position. Or a perforated cover in zinc with a sheet of asbestos cloth
may be adopted to fit over the flange of the well, and in that case the carbon block
would be removed and the charcoal only used.
The filter will be charged with granulated charcoal up to the top of the flange on
the well, and the carbon block placed above in the manner as herein described. The
water will pass in at the bottom of the filter and pass through the perforations of
the metal cap and ring, work its way through the granulated charcoal upwards, and
percolating through the carbon block, down the outside of the earthenware collar
and into the well beneath, and out of the overflow or bib tube in a continuous run
regulated by the supply at the bottom.
When the carbon block is omitted the water will only pass through the granulated
charcoal, sheet of asbestos cloth and zinc perforation on the underside of the cover
and into the well as in the manner before described.

page_text: The connecting fittings at the base of the filter are constructed with a combination
of a bib cock, and a valve situated in a cross, my object being not to stop the supply
of unfiltered water, which is conducted by the bib tap opposite the part of the cross
connected to the supply pipe. On one of the remaining arms of the cross
insert a
valve, to shut off the water from passing through the filter, or to turn the valve in
the opposite direction to permit the water to flow through the filter as herein
described.
I construct this combination of the valve in the cross piece, to permit the water to
run through the bib tap and the filter at the same time.
A stop cock is inserted between the cross piece and the filter to regulate the
pressure of water.
The filter is supplied with an outside metal case to protect the earthenware
cylinder.

COMPLETE SPECIFICATION.
Improvements in Water Filters.
1, ROBERT GOUGH, of 31 Walpole Street, Chelsea, in the County of Middlesex,
Engineers Clerk," 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 :—
My invention relates to an improvement in the construction of water filters
attached to the supply pipe of any domestic establishment, for the purpose of
providing a running supply of purified or defecated water, for drinking or for any
other mode of consumption.
The object of my invention is to attach this said filter either near or above the
position of any ordinary bib tap or valve where it is usually situated, for the purpose
of obtaining water from the supply of a cistern or the main; by first removing this
aforesaid bib tap or valve, and connecting the filter, by the fittings supplied and in
connection with my invention; so that when my invention is duly fixed to the supply
pipe, cause a running supply of purified water to run continuously.
My invention is constructed in a cylindrical form of glazed earthenware, or of any
other material, with one or two openings at the bottom, and a flanged top with lugs,
cars, or flanges, for the purpose of attaching the cover by two or more screws being
passed through holes in the lugs, ears, or flanges, and the cover screwed down by fly
nuts. The top of the glazed earthenware cylinder, bas an opening provided a short
distance downwards, with a sunk well running round the circumference of the
outside of the cylinder with a flanged collar projecting upwards. A bib piece of
metal tube is fixed above the well for the purified water to flow outwards.
At the bottom of the cylinder, situated in the centre is an opening to connect
the supply, and is formed with a flanged bush piece with a male thread outside,
and a leather washer or washers, passing through the hole, and a metal cap with
perforations, screwed on to the bush to hold it in its position. A perforated metal
ring slides over the perforations in the aforesaid cap to prevent any of the loose
granulated carbon passing down into any of the fittings.
On the inner flange above the well is placed a ring of india rubber and a solid
block of carbon inserted in an earthenware ring the same size as the flange of the
well; and when the outer cover is screwed down, a small plug is also screwed down
from the centre of the cover on to the top of the solid block of carbon to secure the
carbon in its position.
The filter is charged with granulated or fine carbon up to the top of the flange on
the well, and a solid carbon block placed. above in the manner as herein described.

page_text: The water will pass in at the bottom of the filter and through the perforations of
the metal cap and ring, working its way through the granulated carbon upwards and
percolating through the solid carbon block, and down the outside of the earthenware
collar into the well beneath, and out of the overflow or bib tube in a continuous run
regulated by the supply at the bottom.
And in order that my Invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof reference being had to letters and figures
marked thereon.
Figure 1, represents the front elevation of the filter, the interior portion being
enclosed in a metal case G, with the metal cover I screwed down by the fly nuts J,
the bolts passing through the metal and glazed earthenware flanges. An iron collar A,
bolted together in two halves and attached to a wall is intend to support the filter in
its fixed position.
The connecting fittings at the base of the filter, are constructed with a combination
of a bib cock P, and a valve 2, situated in a cross B, and a regulator 3. The supply
of unfiltered water is conducted through the bib piece or tap P by opening the
valve 1, opposite the part of the cross connected to the supply pipe when fixed. The
supply valve 2, is intended to shut off the water from passing into the filter,
or to open the valve to permit the water to flow through the filter as herein
described.
I construct the said combination valve so as to permit the water to run through the
bib tap P, and into the filter at the same time.
A union C is for connecting or disconnecting the filter to or from the water service
or fittings.
Figure 2, denotes a section of the filter and fittings connected together by the
union C, with the bush piece secured to the glazed earthenware cylinder D, and the
case G, by the perforated cap R, the perforated metal ring O placed over the perforations
of the cap R.
The cylinder or stoneware chamber D is filled with granulated carbon N, to the
top of the mouth of the chamber, and the solid block of carbon L in the ring F, is
secured by the plug K, with the india rubber ring M placed between the edges of the
ring and the mouth of the chamber.
The way the water travels from the valve to the bib piece H is indicated by arrows,
which is as follows:-The water passes up through the fittings into cap R working
its way through the perforations of the ring O into the granulated carbon N, upwards,
and percolating through the solid block of carbon L and down outside the earthenware
collar Finto the well E and pass out of the bib tube H.
Figure 3, is a plan of the combination cross B on line a, b, of Figuro 1, describing
the male thread to screw into or connect to the socket of any ordinary bib tap in
the supply pipe.
The regulating valve 3, is intended to regulate the supply of water passing into
the filter.
$
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 :-
First The combination of the filter to be attached to the supply pipe of any
domestic establishment, or main, for the purpose of providing a running supply of
purified or defecated water, for drinking or any other mode of consumption, and a
supply of unfiltered water at the same time, substantially as herein described and
according to the accompanying drawings.
Secondly: The combination of the earthenware chamber D holding the carbon N,
with the block of carbon L in the collar F secured by the cover I and the plug K,
and the india rubber ring M and the well E with the bib tube H, the whole enclosed
in the metal case G and fixed together by bolts and fly nuts J for the purpose of
filtering or purifying a continuous supply of water, substantially as herein described
and according to the accompanying drawings.
