IMPROVEMENTS IN FILTERING APPARATUS to be as follows
Year: 1884

page_text: I FRANK HOWARD LANDON, of Queen Victoria Street in the City of London,
Civil Engineer do hereby declare the nature of said invention for "IMPROVEMENTS
IN FILTERING APPARATUS to be as follows:
"
My invention relates to apparatus for filtering water for drinking or other
purposes.
According to the said invention I provide a filter with a flexible tube and a tap
or cock to be used in the following manner-that is to say I place the filter; with
the tube attached by one end as hereinafter described, in the water to be filtered;
this water may be contained in any vessel or receptacle open or closed; the other
end of the said tube is extended to the outside of the vessel and has attached to it
the said tap or cock. The portion of tube outside the said vessel is arranged to be
longer than the portion inside the vessel, so that the tap is at a lower level than
the filter, I thus provide my apparatus with a syphon which enables me to draw
off pure water through the tap as required, after the air has been exhausted
from the tube.
The body of the filter consists of a jar with perforations in its bottom, or sides,
or both. The perforations may be made either in the substance of the jar, or in
separate material attached to it.
The jar has an aperture and neck at the top, or
other convenient place, to which the tube is to be attached. The neck may either be
formed as part of the jar or may be made of one or more separate pieces of
earthenware, metal or other suitable substance, and may have a strainer or strainers
of perforated metal, felt or like material fixed to, or used in connection with, it.
A strainer may be used at the bottom of the jar in addition to the perforations
above specified and may be composed of felt, cotton, or other suitable material.
The aforesaid jar contains the filtering materials, which are closely packed
therein. For this purpose I use loose charcoal or other material whose properties
cleanse and purify the water in its passage through the filter.
The tube may be attached to the jar and made tight by its own elastic pressure
or by any other couvenient method; and may be made of India rubber or other
flexible material. The said tube requires no fixing in any particular position, but
may hang loosely over the side of the vessel containing the water to be filtered.
The tap or cock may be attached to the tube by the elastic pressure or by other
convenient means.

page_text: I, FRANK HOWARD LANDON, of Queen Victoria Street, in the City of London,
Civil Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN FILTERING APPARATUS, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
According to the said Invention I provide a filter with a flexible tube and a tap
or cock to be used in the following manner, that is to say:-1 place the filter, with
the tube attached as hereinafter described, in the water to be filtered. This water
may be contained in any vessel or receptacle, open or closed; the other end of the
said tube is extended to the outside of the vessel, and has attached to it the said
tap or cock. The portion of the tube outside the said vessel is arranged to be
longer than the portion inside the vessel, so that the tap is at a lower level than
the filter. I thus provide my apparatus with a syphon, which enables me to draw
off pure water through the tap as required, after the air has been exhausted from
the tube.
The body of the filter consists of a jar with perforations in its bottom or sides or
both. The jar may be made of earthenware, metal, or other suitable material.
The perforations may be made either in the substance of the jar, or separately and
attached to it. The jar has an aperture and neck at the top or other convenient
place, to which the tube is to be attached. The neck may either be formed as
part of the jar or may be made of one or more separate pieces of earthenware,
metal, or other suitable substance, and may have a strainer or strainers of
perforated metal, felt, asbestos, or like material fixed to or used in connection with
it. A strainer may be used at the bottom of the jar in addition to the perforations
above specified, and may be composed of metal felt, asbestos, or other suitable
material.
The aforesaid jar contains the filtering material. For this purpose I use loose
charcoal or other material, whose properties cleanse and purify the water in its
passage through the filter.
The tube may be attached to the neck or cap of the jar, and made tight by its
own adhesive pressure, or by any other convenient method, and it may be made
of india rubber or other flexible material. The said tube requires no fixing in
any particular position, but may hang loosely over one side of the vessel containing
the water to be filtered. The tap or cock may be attached to the tube by its own
adhesive pressure, or by other convenient means.
To 'more clearly explain and illustrate my invention, I annex hereto a drawing
showing one form of the filter in operation, and the manner of its use. Referring
to the said drawing: A shows an earthenware jar with a perforated bottom,
containing the filtering material; B is the neck or cap; C is the tube; and D the
tap or cock.
The jar is shown placed in a pail (marked E on the drawing)
containing the water to be filtered. After the air has been exhausted from the
tule C, the water, entering through the perforations in the bottom of the jar,
and a-cending through the filtering material, is cleansed and purified, and flows
through the syphon formed by the tube, into a jug, or other receptacle (marked F
on the drawing.)

page_text: 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:
1st. The use of a jar containing filtering materials, a flexible tube, and a tap, in
combination, in the manner herein before set forth.
2nd. The use of a jar with a separate perforated bottom attached to, or used in
combination with, it.
