Improvements in Filters.
I, WILLIAM HUMPHREY WHEATLEY of the Firm of Wheatley & Mackenzie,
Engineers and Patent Agents of 40 Chancery Lane in the County of London, (a
communication to me from Charles Theodore Strauss of 487 Broadway, New York, in
the County and State of New York, United States of America, 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 invention has reference to improvements in filters used for water-pipes and has
the object, first, to purify the water conducted through the filter and, second, to
impart to the water, by the appliance of suitable chemicals, a certain amount of
oxygen or a required flavor. This is attained by the construction shown in the
accompanying drawings in which
Fig. 1 is a vertical section of this improved filter,
Fig. 2 a section on line x-x of Fig. 1, and
Fig. 3 a portional vertical section of a modified construction of the filter.
A in the drawings represents a box of metal, artificial stone, or any other material,
which is divided into three compartments a, b, c by vertically traversing
partitions B and C, of which the partition B may be integral with the box or may
be of any solid material, and the partition C consists of porous natural or artificial
stone, or of perforated sheets e¹ e¹ of non-corrosive material and gravel, granulated
charcoal cr other filtering material f, by which the space between the said perforated
sheets is filled up, as shown in Fig. 3. The partition B has on its top an opening b₁
and a screen b³ extending from the bottom of the opening 6' to the front wall of the
box, parallel with the cover F of the latter, as shown in Fig. 1. In the chamber a a
fly-wheel D is located, to the ends of the radial blades or wings of which a covering
of non-corrosive wire-gauze, perforated sheet metal or any other perforated material
may be applied, so that thereby a revoluble cylinder is obtained which revolves on
its axle or shaft d and has its bearings in the end walls of the box or case.
In the
middle of the compartment c, two vertically traversing screens g g are located, the space
between which is filled with carbonized sponge g₁ saturated in any approved manner
with oxygen or with any other oxygen containing ingredients or chemicals.
The box or case of the filter is placed between the ends of the water-conducting
pipes G G', so that the pipe G enters the compartment a and the pipe G¹ is connected
with the compartment c.
The water in entering the compartment a is forced upon the wheel or cylinder D and,
by its pressure upon the radial blades or wings causes the wheel or cylinder to revolve
on its axle or shaft. The rotation of the wheel or cylinder, which acts as a separator, causes
the
gross particles contained in the water to be deposited on the bottom of the compart-
ment a, for which purpose a space is left between the periphery of the wheel and the
bottom of the box, as shown in Fig. 1, and the water thus separated from dirt and
other gross particles flows through the top-opening b' of the partition B into the
compartment b. Lighter particles are detained in the compartment a by the screen 62
attached to the top-portion of the latter. From here it is forced by its own pressure
through the
porous partition C, which retains further noxious ingredients which were
not separated from the water by the previous action of the revolving separator D, so that
the water enters the partition c in a more purified condition. It is a fact that the water
conducted through metal pipes loses a certain quantity of oxygen in solution or

page_text: suspension therein. To recharge the water with the lost oxygen is the object of the
traversing screens g g holding the oxygen containing ingredients, as said before. The
water entering the compartment c absorbs a certain quantity of oxygen contained in
the said ingredients and the chemicals consume or destroy at the same time all spores,
bacteria, &c., contained in the water, so that the same enters the outlet pipe Gi in a
chemically pure state.
After a certain time of use of the filter the sediments in the compartment a are
removed by withdrawing the plug H in the bottom of the same, and the cover F may
be taken off and the wheel and compartments cleaned for further use.
It is evident that the filter can also be used for other fluids and the screens g g
filled with ingredients to impart to such fluids a certain flavor or perfume.
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 :-
1. A filter consisting of a box having compartments formed by partitions, one partition
being provided with a top opening, and the other partition being of porous material,
and a revoluble wheel or perforated cylinder in the first compartment having the
partition with the top-opening, in combination with fluid-conducting inlet and outlet-
pipes, substantially as set forth.
2. A filter consisting of a box having three compartments formed by partitions, one
partition being provided with a top-opening and the other being of porous material, a
revoluble wheel or perforated cylinder in the compartment having the partition with
the top-opening, and traversing screens holding chemicals for the purpose described
in the third compartment, in combination with inlet and outlet pipes, substantially
as set forth.
3. A filter consisting of a box having three compartments formed by partitions, one
partition being provided with a top-opening and the other partition consisting of
porous material or perforated sheets filled up with filtering material, a revoluble wheel
or perforated cylinder, and a horizontally traversing screen in the first compartment
having the partition with the top-opening, and traversing screens holding chemicals
for the purpose described in the third compartment, in combination with inlet and
outlet pipes, substantially as set forth.
Dated this 5th day of January 1897.
