COMPLETE SPECIFICATION.
An Improved Apparatus for the Filtering of Water.
I GEORGE LUFF STOCKER of 276 Portobello Road North Kensington Manager
of The Gem Water Filter Company, 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 consists of a tubular cylinder casing heavily plated turning
inwards having at either end removable bell shape caps with peculiar woven wire
gauze partitions secured by two layers of rubber and between these partitions I
place granulated charcoal (or other filtering medium) and about half way between
the woven wire partitions and imbedded in the filtering material I place a very
important third partition composed of a substance which the animalcular sediment
cannot corrode namely perforated mica (or other non-corrodible substance) and
this apparatus has for its object the perfect filtration of water cheap and convenient
for domestic purposes, where water works exist and the water conveyed through
pipes and drawn by faucet or tap.
And in order that my invention may be the better described and understood I
have appended the accompanying sheet of drawings No. 3 properly marked and
numbered in which
Figure 1 represents an elevational view of my complete device.
Figure 2 is a vertical section of the same showing the several parts in all their
proper positions.
Figure 3 shows the rubber cone complete in itself detached.
Figure 4 shows the perforated mica disc for distribution of water which I make
in various shapes with its perforated holes also detached.
I first provide a metal cylinder A curved ends as shown in Figure 1 & 2
this contains the filtering material B as shown in Figure 2 in the centre of the
filtering material I place a perforated mica disc C as shown in Figure 2 as also
Figure 4 detached.
At each end of the cylinder, I screw in a cup shaped cap D and E as shown in
Figure 1 and 2.
Inside these cup shaped tops of the cylinder I place peculiar woven wire screens F
and Gas shown in Figure 2 inside the wire screen that rests in a prepared groove

page_text: I place a rubber washer upon which comes the curved ends of the cylinder A to
make a tight perfect joint.
Each screen is placed between two rubber washers which are fitted into prepared
grooves in D & E and round this wire screen I place a stiff rubber washer
holding the same in position which is secured there by the curved rim of the
cylinder A being screwed down upon the rubber making another perfect joint
at the same time securing the silex material for filtration as shown in Fig. 2
marked B. inside the cup shaped tops of the cylinders D and E to make then
water tight.
The bell shaped union K and L as shown in Figure 1 and 2 are screwed at the
junction of which to prevent leakage I place also other rubber washers Maud N
as shown in Figure 1 and 2. Also fitted inside and under the curved rim union K
and L are rubber cones P and Q so made as to fit perfectly tight without any cap
screw and ever ready for use and the harder the wear the tighter they get. See
Figure 3 rubber cone detached also as in position in Figure 1 and 2.
Figure 4 is the perforated mica disc detached which can be varied to any shape.
This is most important for the successful working of the filter in distributing the
water to every part producing a steady flow of water free from animalcule sediment
and cannot corrode.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be used I would observe in
conclusion that what I consider to be novel and original and therefore claim as
the invention secured to me by Letters Patent is.
Firstly. The non-corrodible perforated mica dise for the distribution and spread
of water in the filter substantially as herein set forth, and can be varied to any
shape or pattern.
Secondly. The filtering apparatus itself in shape as shown in Figure 1 and 2 as
a new article of manufacture combining the novel connection of an article to filter
water from a faucet tap and connection to render self-cleansing easy and effectual
substantially as berein set forth this Twenty first day of June, One thousand eight
hundred and ninety four.
