AN IMPROVED HIGH PRESSURE FILTER, APPLICABLE TO WATER TAPS OR FEED-PIPES
Year: 1885

page_text: I WILLIAM JAMES BAKER of the firm of Turner and Baker, Patent Agents and
Consulting Engineers, Town Hall Chambers, Market Street, Bradford, in the
County of York do hereby declare the nature of my invention for "AN IMPROVED
HIGH PRESSURE FILTER, APPLICABLE TO WATER TAPS OR FEED-PIPES
cation from abroad by James Henry Bleasdale of Cleveland Ohio, in the United
(a communi-
States of America, Telegraph Clerk) to be as follows:-
"
My invention relates to a small filter which may be screwed upon an ordinary
water tap or inserted between lengths of feed pipe by means of which water is
conveyed to boilers or cisterns.
To carry out my invention I form a hollow cylinder of metal, hard rubber, or
other suitable material and at each end of such cylinder I fix a flange having
formed in or upon it a male or female screw for connection to the water supply
pipe. Both these screwed flanges are exactly similar in form and in the size of the
screws so that either end of the cylinder can be screwed to the supply pipe as
desired.
At each end of the cylinder and within the screwed flange is placed a disc of wire
gauze which is held in position by an india-rubber washer which is pressed upon
by the nozzle of the supply pipe when screwed into its place.
A bridge or partition is formed across the centre of each end of the cylinder or
within the flanges hereinbefore mentioned for the purpose of dividing the stream
of water passing through the filter and causing such stream to pass through a
larger surface of filtering material and the bridges or partitions are held together by
a short stay which passes from one end of the cylinder to the other in the line of
its axis.
The cylinder is filled with animal charcoal, porous stone, pounded glass or other
suitable filtering material which is held in position by the discs of gauze at the

page_text: ends of the cylinder hereinbefore referred to. These discs of gauze also serve to
prevent the ingress of larger particles of dirt into the body of the filter.
When the filter has been a short time in use it is unscrewed from the supply tap,
and reversed, so that the water may pass through it in an opposite direction,
whereby the deposit of dirt or sediment that was formed upon what was originally
the top of the filter, is then washed out at the bottom, before the water passing
through is again made use of for drinking purposes.
A suitable nozzle is soldered or otherwise fixed to the water supply pipe in or
upon which nozzle the screwed flanges at the ends of the filter may fit.
The filter herein described is self cleansing, easily refilled with fresh filtering
material, and may be applied to any existing tap or pipe by means of suitable
screws or flanges.

I, WILLIAM JAMES BAKER of the firm of Turner and Baker, Patent Agents and
Consulting Engineers, Town Hall Chambers, Market Street Bradford, in the
County of York do hereby declare the nature of my invention for AN IMPROVED
HIGH PRESSURE FILTER APPLICABLE TO WATER TAPS OR FEED PIPES (a communi-
cation from abroad by James Henry Bleasdale, of Cleveland Ohio in the United
States of America Telegraph Clerk), 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 a small filter which may be screwed upon an ordinary
water tap, or inserted between lengths of feed pipe by means of which water is
conveyed to boilers or cisterns.
To carry out my invention I form a hollow cylinder of metal, hard rubber or
other suitable material, and at each end of such cylinder I fix a flange having
formed in or upon it a male or female screw, for connection to the water supply
pipe. Both these screwed flanges are exactly similar in form, and in the size of
the screws, so that either end of the cylinder can be screwed to the supply pipes as
desired.
At each end of the cylinder, and within the screwed flanges, is placed a disc of
wire gauze which is held in position by an india rubber washer, which is pressed
upon by the nozzle of the supply pipe, when screwed into its place. A bridge or
partition is formed across the centre of each end of the cylinder, or within the
flanges hereinbefore mentioned, for the purpose of dividing the stream of water
passing through the filter and causing such stream to pass through a larger surface
of filtering material, and the bridges or partitions are held together by a short
stay which passes from one end of the cylinder to the other, in the line of its axis.
The cylinder is filled with animal charcoal, porous stone, pounded glass, or other
suitable filtering material, which is held in position, and prevented from escaping
from the cylinder, by means of the discs of gauze at the ends of the cylinder
herein before referred to.
The discs of gauze also serve to prevent the ingress of larger particles of dirt
into the body of the filter.
When the filter has been a short time in use, it is unscrewed from the supply
tap and reversed, so that the water may pass through it in an opposite direction,
whereby the deposit of dirt or sediment formed upon that surface of the filter
which was originally uppermost (and which surface will now be at the bottom) is
washed off and passes away before the water passing through the filter is again
made use of.
A suitable nozzle is soldered, or otherwise fixed to the water supply pipe, in or
upon which the screwed flanges at the ends of the filter may fit.
The filter herein described is self cleansing, easily refilled with fresh filtering
material, and may be applied to any existing tap or pipe by means of suitable
screws or flanges.
In order to enable my invention to be fully understood, I will proceed to
describe the same with reference to the accompanying drawings, in which Figure 1

page_text: represents an elevation of my improved filter attached to an ordinary water tap.
Figure 2 represents a sectional elevation of the same, and Figure 3 represents an
elevation of the filter applied to the feed pipe of an ordinary steam boiler or
cistern.
Similar letters refer to similar parts in all the drawings. The cylinder or barrel
of the filter is represented at A, which cylinder contains the granulated carbon
or other filtering material. At each end, or at the top and bottom of the cylinder
or barrel are flanges B upon which are formed screw threads, when the flanges are
required to fit upon an ordinary water tap, or with flat flanges secured by bolts
and nuts, when required to be fixed to the feed pipe of a steam boiler or cistern as
represented at Figure 3.
Within the flanges B are formed ledges, one in each flange, upon which ledge
rests the disc of wire gauze C and upon the edge of each disc is placed an elastic
washer D which is pressed upon by the nozzle E when screwed into its socket in
the flange B, thereby holding the gauze securely in its place.
The flanges B at each end of the cylinder or barrel of the filter, are held at a
fixed distance from each other, and are also held to the sides of the cylinder by
means of bridges F, which are connected by a screwed stay G, which passes
through the crown of both bridges in the line of the axis of the cylinder. The
bridges also serve to break up the stream of water passing through the filter, and
diffuse such stream more thoroughly through the filtering material H.
The wire gauze C hereinbefore referred to is for the purpose of confining the
granulated carbon H or other filtering material within the cylinder or barrel of the
filter, and preventing its escape therefrom, either when a stream of water is passing
through the filter or when the filter is unscrewed from the water tap, and these
discs of gauze also prevent the ingress of large particles of dirt or impurities into
the body of the filter.
When the filter as herein before described has been a certain time in action, the
surface of the filtering material or of the upper disc of gauze will become coated
over by the impurities or sediment extracted from and left by the water. The
filter can then be unscrewed at the flange which is for the time being uppermost,
and when reversed, screwed again upon the water tap, by which means the water
will be caused to flow through the filter in the opposite direction, and will wash
off the deposit left upon the surface of the filtering material or upon the discs of
gauze.
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,
1. The construction and use of a filter which may be attached to an ordinary
water tap or feed pipe, which filter has gauze discs secured in the manner described,
and the cylinder or barrel for the purpose of containing the filtering material
and fitted with bridges and flanges as described; all arranged and operating
substantially in the manner, and for the purpose as herein set forth or any mere
modification thereof.
2. The construction and arrangement of similar flanges at each end, of or at the
top and bottom of the filter, to enable the filter to be reversed, in the manner and
for the purpose substantially as described.
