PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Boiling and Filtering Water.
BENJAMIN HAUGHTON, Civil Engineer, of 1 Victoria Street, London, S. W.,
a communication from Walter Raleigh Haughton Civil Engineer, East Bengal
State Railway, Rajbari, Furreed pore, Bengal, India, do hereby declare the nature
of this invention to be as follows:-
The apparatus consists of two parts or vessels, A the boiler, & B, the filter,
which are made of wrought iron, earthenware, or other material. Each part as a
whole, forms a cylinder, & stands upon its end, upon a wrought iron folding support.
The latter consists of a high & low level, both taken together forming a pair of
steps. A, rests on the upper step, B, on the lower one.
The lower third part of A, contains a kerosene lamp, or a gas jet. The lamp
chimney is of sheet metal, & passes through the foul water cistern, which occupies
the upper two thirds of A. Thus the water is boiled. There may be two lamp
chimneys or more, so as to ensure rapidity in the process of boiling. B, consists
of a pure water cistern in its lower third part. The upper two thirds is a filter
pan, & rests on top of the pure water cistern, dropping within it, & contains the
filtering medium. It can be removed by lifting it out, & may thus be thoroughly
cleansed. The process which the water undergoes, is, viz., it is boiled in part A,
from which it passes through a tap into B, on the lower step of the support. It is
here filtered & deposited in the pure water cistern in lower third of part B, where
it is found to be a perfectly pure, clear, & potable liquid.

Improvements in Apparatus for Boiling and Filtering Water.
A communication from WALTER RALEIGH HAUGHTON, Civil Engineer, of
Furrccdpore, Bengal, India.
I BENJAMIN HAUGHTON, Civil Engineer, 1 Victoria Street, London, S.W., 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:-
This invention consists of two vessels A and B which are brought into conjunction
for the purpose of improving the quality and purity of water intended for drinking
purposes, and is chiefly intended to be used in tropical countries, where it is a
matter of necessity that water should be boiled before drinking, so that diseasc
germs may be destroyed, with the result that fever and dysentery and cognate
complaints, those bancs of tropical life may be combated, which are now accountable
for the loss of hundreds of perfectly good lives.
A is a boiler, which has a lamp beneath, in which kerosine or spirit or gas may
be used. The flames pass through one or more tubes in the boiler, & thus secure
rapidity and economy in bringing the water to boiling heat.
B is a filter and consists of two parts, or chambers, C and D, C contains the
filtering medium. It receives the water from the boiler, through a small bore
pipe & tap, and passes it by gravitation into a cistern D, from whence it runs into
a collecting vessel of glass, or other material that may be fancied, to drink from.
The drawing accompanying, shows also a chest, to be used in a two-fold capacity,

page_text: viz., as a case in which the apparatus may be packed up when travelling, and also
as a stand for supporting the same when in operation, E. E. E.
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 as features of novelty, are,
1. The bringing into contiguity, the two separate processes of boiling, and
filtering, for the production of an absolutely pure and potable water.
2. The adoption of a chest, for carrying about the apparatus when travelling.
