PROVISIONAL SPECIFICATION.
A Portable Apparatus Comprising a Filter and Means for Supplying
Water under Pressure to the same.
We WILLIAM VARBALL and FRÉDÉRIO BRISSE, both of 1 Boulevard St. Denis,
Paris, France, Engineers, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct a portable apparatus comprising a filter
and suitable for use more particularly in places where there are no means of distri-
buting water under pressure. The improved apparatus provides for the supply at any
time of a large quantity of filtered water.
The apparatus consists mainly of two reservoirs, one for containing water at
atmospheric pressure and the other for containing water at a greater pressure, this
second reservoir being connected by a pipe with a filter, which forms an integral part
of the apparatus, and may be of any suitable kind.
According to one modification of the invention the two reservoirs are arranged
concentrically, one within the other, the outer one being for water at atmospheric
pressure and the other for water under pressure. The filter is fixed to the outside
of the outer vessel and is in communication by means of a pipe with the inner
vessel. The necessary pressure in this vessel can bo obtained by means of a pump
which draws water from the outer vessel, or if desired the ambient air and pumps
it through a pipe into the inner vessel. Or instead of a pump other means for
producing the necessary pressure in the inner vessel can be employed, such as, for
example, a compressed air reservoir fitted with a cock through which the air can
be discharged as required into the inn.r reservoir.
The filter is fitted with a tap by which the water forced into it from the inner
vessel can be drawn off as required.
If the apparatus be made strong enough to support high pressure the water can
be sent to a distance or to the upper floors of a house, and in this case the filter
will have a second delivery outlet from which a pipe will lead to the place to which
the water is to be conducted.
The inner vessel is provided with a safety valve placed upon a suitably arranged
pipe, and also with other accessory parts such as an emptying or cleansing
cock.
According to another modification the reservoir for containing the water under
pressure is placed outside the reservoir for containing water at atmospheric
pressure.
The apparatas is preferably fitted with rollers or wheels and with a handle to
allow of its being readily moved froin place to place.

COMPLETE SPECIFICATION.
A Portable Apparatus Comprising a Filter and Means for Supplying
Water under Pressure to the same.
We WILLIAM VARRALL and FRÉDÉRIO BRISSE both of 1 Boulevard St. Denis,
Paris, France, Engineers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
5 ascertained in and by the following statement :-
The object of this invention is to construct a portable apparatus comprising a

page_text: filter and suitable for use more particularly in places where there are no means of
distributing water under pressure. The improved apparatus provides for the supply
at any time of a large quantity of filtered water.
The apparatus consists mainly of two reservoirs, one for containing water at
atmospheric pressure and the other for containing water at a greator pressure,
this second reservoir being connectal by a pipe with a filter which forms an integral
part of the apparatus, und may be of any suitable kind.
According to one modification of the invention which is represented in elevation
in Figure and in vertical section in Figure 2 of the annexed drawings the two
reservoirs are arranged concentrically one within the other the outer one A being
for water at atmospheric pressure and the other B for water under pressure. The
filter is fixed to the outside of the outer vessel A and is in communication by
means of a pipe e" with the inner vessel B. The necessary pressure in this vessel
can be obtained by means of a pump C which draws water from the outer vessel
by the pipe e (or if desired draws the ambient air) and pumps it through a pipo e²
into the inner vessel. Or instead of a pump other means for producing the necessary
pressure in the inner vessel can be employed, such as for example a compressed nir
reservoir fitted with a cock through which the air can be discharged as required
into the inner reservoir.
The filter D is fitted with a tap by which the water forced into it from the inner
vessel can be drawn off as required into a vessal such as E.
If the apparatus be made strong enough to support high prossuros the water can
be sent to a distance or to the upper floors of a house, and in this case the filter will
have a second delivery outlet as in Figure 2 from which a pipe will lend to the place
to which the water is to be conducted.
The inner vessel B is provided with a safety valve placed upon a suitably
arranged pipe a and also with other accessory parts such as the emptying or cleansing
cock a¹.
According to another modification reprosented in Figure 3 the reservoir B for
containing the water under pressure is placed outside the reservoir A for containing
water at atmospheric pressure.
The apparatus is preferably fitted with rollers or wheels ee and with a handle d
to allow of its being readily moved from place to place.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
A portable apparatus comprising a filter and means for supplying it with water
under pressure, the said means including a reservoir for containing water at
atmospheric pressure and a reservoir for containing water under pressure, these two
reservoirs being connectol together and the reservoir containing water under prossuro
being connected with the filter, substantially as set forth.
