'I, HENRY HARRIS, of 67 Oakley Road Islington, in the County of Middlesex, Patentee
for IMPROVEMENTS IN WATER FILTERS, 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:-
The nature of my Invention is the construction of a powerful Automatic Portable
self filling and self cleansing Water purifying Apparatus to enable any water Supply
to be thoroughly filter'd and purified in its upward passage, through a Filtering Bed,
and from thence through a purifying Chamber into a Reservoir, thus affording a
continuous and unlimited supply of Pare Water for all dietary and sanitary usage."
For the better explanation of my Invention I refer to the Drawings hereunto
annexed. Fig. 1. represents the Automatic portable self-filling and self cleansing
Water purifying Apparatus, divided into four distinct Chambers A. B. C. D. connected
by perforated plates c. c. c. The lowest Chamber A. receives the Water supply by inlet a.
from whence the water ascends into Filtering Chamber B. which is filled with the
most approved filtering Media. From this Chamber the Water thus filter'd continues
its ascent into Purifying Chamber, C, which is filled with tightly compressed silicated
Animal Carbon.
The Water thus filter'd and purified enters the Reservoir Chamber, D. ready to be
drawn off at Will, in a continuous and unlimited supply, from the Pure Water Tap E.
The letter F. is a flexible tube for connecting the Purifying Apparatus to any Water
supply obtainable, specially adapted for the use of the Army & Navy in Barrack or in
Campaign. Fig. 2. represents the Purifying Apparatus fix'd to the Household Water
Supply pipe a. by Union Tap and joint A. A. for the constant Supply of the Ordinary
Water to the Apparatus, which becomes Purified by the same process, as already
described by Fig. 1. and the pure Water is conducted through the pure
Water pipe, C. to the outlet D. when required. This Apparatus for domestic
usage, is further supplied with a Cleansing tap or Valve E. by which the
apparatus is entirely and regularly flushed with its own purified Water from
above. Fig. 3-A small portable apparatus, with inner Works of the same con-
struction as in figure 1. for the use of Tourists and travellers, and Sea side Visitors.
A, sheweth its connection by flexible tube to any ordinary Tap-and simply hung on

page_text: a Nail ready for use. Fig. 4. represents a small Pocket Apparatus for immersion in
Ponds, streams, or any vessels containing Water. This Apparatus is constructed on
the same principle as is described in fig. 1. having a flexible tube and Mouth Piece,
for drawing the Water thus purified by suction.
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
Firstly. The Duplex Action of filtration and Purification carried out by the means,
and in the manner herein before described.
Secondly. The automatic Action of selffilling and self cleansing, by the com-
plete and continual flushing of the interior of the Apparatus with it's own purified
Water.
