Complete Specification' Accepted, 26th Oct., 1888
1, SAMUEL ALBERT JOHNSON of 13 East India Road, Poplar, in the County of
Middlesex, Marine Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object an improved ship or other filter having a storage
chamber and draw off tap for the filtered water and a passage or chamber around the
filtering block communicating directly with a draw off tap whereby the filter may
be readily cleansed.
In carrying my invention into effect I employ a filter body in the lower part of
which I form a reservoir for filtered water; I form a recessed chamber in the said
reservoir within which I fix a central rising tube perforated around its sides and closed
at its upper end around which part I form a screw thread; around this perforated
pipe or tube and resting on a suitable packing washer at the bottom end I pass a
filtering block which is held in position by a nut working on the screw thread of the
perforated pipe and provided with a suitable packing washer between it and the
filtering block, a small space is left around the filtering block and between it and
its containing chamber and a reservoir or chamber is formed above the filtered water
reservoir to receive unfiltered water. A tap is fitted to the filtered water chamber
and a tap and way are connected with the chamber containing the filtering block so
as to enable the unfiltered water to be drawn off directly if desired either for the
purpose of cleansing the filter or otherwise.
An air tube rising from the top of the filterd water chamber to the top of the
unfiltered water chamber permits the escape of the contained air from the filtered
water chamber as filtered water passes into the same.
By having a reservoir to collect the water as it is filtered there will generally be
a store of filtered water available for immediate use.

page_text: J. SAMUEL ALBERT JOHNSON of 13 East India Road, Poplar, in the County of
Middlesex, Marine Engineer, 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 has for its object an improved ship or other filter having a storage
chamber and draw off tap for the filtered water, and a passage or chamber around
the filtering block communicating directly with a draw off tap, whereby the filter
may be readily cleansed.
My improved filter is represented in the accompanying drawings, in which
Figure 1 is a front elevation, Figure 2 is a plan, Figure 3 is a vertical section drawn
on the line 1. 1. of Figure 2, Figure 4 is a horizontal section drawn on the line 2. 2..
of Figure 3 with the filter block removed, Figure 5 is a vertical section on the
line 3. 3. of Figure 2, and Figure 6 is a plan of the filter block separately.
In carrying my invention into effect, I employ a filter body or container a, in the
lower part of which I form a reservoir for filtered water. In the reservoir I
form a recessed chamber c, within which I fix a central rising tube d perforated
around its sides and closed at its upper end, around which part I form a screw thread;
around this perforated pipe or tube d, and resting on a suitable packing washer e at
the bottom end, I pass a filtering block, which is held in position by a nut g
working on the screw thread of the perforated pipe d, and provided with a suitable
packing washer between it and the filtering block. A small space is left around the
filtering block, between it and its containing chamber c, and a reservoir or chamber h
is formed above the filtered water reservoir b to receive unfiltered water. A tap i is
fitted to the filtered water reservoir b, and a tap and way are connected with the
chamber c containing the filtering block f, so as to enable the unfiltered water to be
drawn off directly, if desired, either for the purpose of cleansing the filter or
otherwise.
An air tube k, rising from the top of the filtered water reservoir b to the top of the
unfiltered water chamber h, permits the escape of the contained air from the filtered
water reservoir b as filtered water passes into the same.
By having a reservoir to collect the water as it is filtered there will generally be
a store of filtered water available for immediate use. In some cases the chamber c
will be fitted with more than one filtering block fand tube d.
I would here remark that I am aware that filtering blocks have been used in
connection with chambers, passages and taps, so that either filtered or unfiltered
water could be drawn off as required: I do not therefore broadly claim such
arrangement.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
-
1. A new or improved ship or other filter constructe.l substantially as herein shown
and described.
2. A new or improved ship or other filter having a reservoir for unfiltered water,
a reservoir for filtered water provided with a tap and air pipe, a recessed chamber
fitted with a filtering block surrounding a perforated rising pipe closed at the top
and opening at its lower end into the filtered water chamber, and a way and tap
connected with the recessed chamber substantially as herein shown and described and
for the purpose stated.
