PROVISIONAL DIECIFICATION.
A New or Improved Filter.
FREDERICK DALE TIPPETTS of No. 17 Grantham Road Birmingham in the
County of Warwick, Manufacturer do hereby declare the nature of this invention
to be as follows:-
My invention consists of a filter the parts of which are constructed and combined
in the manner hereinafter described whereby a simple efficient and inexpensive
filter is produced especially adapted for domestic use but applicable as a filter
generally.
I make the body or case of the filter preferably of metal and of an ellipsoidal or
egg shape. The said body or case is made of two nearly similar semi-ellipsoidal
balves connected together by screwing. The body or case is open at both ends
one end having a funnel shaped mouthpiece lined with india rubber by which
mouthpiece it can be attached to the nozzle of an ordinary tap the other end may
have a short delivery pipe. The said mouthpiece and delivery pipe are attached
to the body by screwing.
In
Each half of the body or case is filled with the filtering material. This consists
of powdered charcoal preferably animal charcoal supported by layers of felt.
filling each half a disc of felt of a size suitable to cover the opening on the end of
the half body or case is placed over the said opening; the half body or case is
then nearly filled with the powdered charcoal and another disc of felt of a size
fitting tightly the interior of the half body or case is placed upon the charcoal.
Each half of the body being thus charged with charcoal held in position by the
discs of felt the two halves are screwed together and the filter is ready for use.
In using the filter it is only necessary to press its mouthpiece onto the nozzle of
the water tap. By opening the said tap the water delivered passes through the
filter and is cleared of any suspended matter.
I prefer to make the screwed openings at the ends of the body or case of the
same size and of the same screw thread so that the mouthpiece and delivery pipe
will fit either end. By this construction the filter may be reversed with respect to
the water tap and the accumulated sediment washed out of the filtering material
from time to time.
Although I have described the use of four discs of felt yet I do not limit myself
thereto and in place of felt discs finely perforated metallic or non metallic discs
may be employed.

COMPLETE SPECIFICATION.
A New or Improved Filter.
I FREDERICK DALE TIPPETTS, of No. 17 Grantham Road Birmingham in the
0 County of Warwick, Manufacturer do hereby declare the nature of my 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 filter the parts of which are constructed and combined
in the manner hereinafter described whereby a simple, efficient and inexpensive
5 filter is produced especially adapted for domestic use but applicable as a filter
generally.

page_text: I make the body or case of the filter preferably of metal and of an ellipsoidal or
egg shape. The said body or case is made of two nearly similar ellipsoidal halves
connected together by screwing. The body or case is open at both ends having a
funnel shaped mouthpiece lined with india rubber by which mouthpiece it can be
attached to the nozzle of an ordinary tap; the other end may have a short delivery
pipe. The said mouthpiece and delivery pipe are attached to the body by
screwing.
Each half of the body or case is filled with the filtering material. This consists
of powdered charcoal, preferably animal charcoal, supported by layers of felt. In
filling each half, a disc of felt of a size suitable to cover the opening on the end of
the half body or case is placed over the said opening; the half body or case is then
nearly filled with the powdered charcoal and another disc of felt of a size fitting
tightly the interior of the half body or case is placed upon the charcoal. Each
half of the body being thus charged with charcoal held in position by the discs of
felt, the two halves are screwed together and the filter is ready for use.
In using the filter it is only necessary to press its mouthpiece on to the nozzle of
the water tap. By opening the said tap the water delivered passes through the
filter and is cleared of any suspended matter.
I prefer to make the screwed openings at the ends of the body or case of the
same size and of the same screw thread so that the mouthpiece and delivery pipe
will fit either end. By this construction the filter may be reversed with respect to
the water tap and the accumulated sediment washed out of the filtering material
from time to time.
Although I have described the use of four discs of felt yet I do not limit myself
thereto and in place of felt discs finely perforated metallic or non metallic discs
may be employed.
Figure 1 of the accompanying drawing represents in vertical section and
Figure 2 in plan, my new or improved filter;
Figure 3 represents the parts of the filter disconnected and with the mouthpiece
and delivery pipe in an inverted position, and
Figure 4 represents a plan of one of the halves of the body or case of the filter.
The same letters of reference indicate the same parts in the several figures of
the drawing.
The sheet metal body of the filter is marked a, a' and is made preferably of two
nearly similar semi-ellipsoidal halves connected together by screwing at b, the
outer screwed edge of one half screwing into the internally screwed flange of the
other half. A liquid tight joint is formed at the screwed junction of the halves of
the case or body by the packing ring c which is pressed between flanges at the
mouths of the said halves. The body or case a, a' is open at both ends, the open
ends being screwed. In one of the screwed ends of the body a funnel or other
shaped mouth piece d, lined with india rubber is screwed. By means of the mouth
piece d the filter can be attached to the nozzle of an ordinary water tap. In the
other screwed end of the body a, a² the short delivery pipe e is screwed. The
screws both of the mouthpiece d and delivery pipe e and the screwed mouths of
the body are of the same size and of the same screw thread so that the mouth
piece or delivery pipe can be attached to the body at either end. Each half of the
body of the filter is filled with the filtering material such as animal charcoal the
narrow end of each half being covered with a. disc of wire gauze or perforated
metal and upon it a disc of felt marked, the wire gauze, or perforated metal disc
being soldered in its place.
Upon these discs at the powdered, filtering material is placed. The half body
having been filled with the filtering material another disc of felt g. is placed on the
top of the filtering material in the said half body so as to close the said half body
and preserve the filtering material in its place. Each half of the body being thus
charged with charcoal, held in position by the disc of felt g, the halves are screwed
together and the filter is ready for use.
In using the filter, the mouthpiece d is pressed onto the nozzle of the water tap,

page_text: the lining of india rubber of the said mouth piece holding the filter tightly and
closely on the tap nozzle. By opening the tap the water delivered by it passes
through the filter and is cleared of any suspended matter, the filtered water being
delivered by the delivery pipe e.
The filtering material may be cleaned or replaced by fresh filtering material by
unscrewing the halves of the body; or the filter may be reversed with respect to
the water tap, that is, the mouth piece d and delivery pipe e may be reversed and
screwed into opposite ends of the body a, a² as seen in Figure 3. When the
positions of the mouth piece and delivery pipe have been inverted, and the filter
attached to the water tap, the accumulated sediment in the filter may be
washed out.
Figure 5 represents partly in vertical section and partly in elevation, a modified
filter made according to my invention. In this modified filter the halves a, a of
the body or case instead of being made capable of separating are permanently
connected together. That is to say after the said halves have been filled with
the filtering material they are connected together by closing their edges at h
upon one another by a spinning process, and soldering their closed edges so as
to form a liquid tight joint. The accumulated sediment in this modified filter-
is washed out by reversing the filter with respect to the water tap as before
described.
Having now particularly described and ascertained the nature of my inven--
tion and the manner in which the same is to be performed I declare that I
claim as my invention :-
The new or improved filter hereinbefore described and illustrated in the
accompanying drawing; that is to say, a filter consisting of a hollow body or
case made of two nearly similar halves containing the filtering material, the
said halves being either screwed together or permanently connected together, the
open ends of the body or case so made being screwed for receiving at one end a.
removable mouthpiece lined with india rubber, for attaching the filter to the nozzle
of an ordinary water tap and for receiving at the other end a removable delivery-
pipe substantially as described and illustrated.
