Roxburgh Villa Phillip Lane Tottenham 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 principal parts I the outer, which is made of
gun metal, or other suitable material, in accordance with the annexed drawings.
II is the interior part consisting of a cylinder of brass, or other suitable material,
fitting exactly into the body E and leaving a space S, between the end of the
cylinder and the back of the body G. This space allows the fluid from the valve B
to play upon the surface of the filter. Leakage is obviated by suitable washers e,
pressed up between the flange on the inside of E, and the rim of the cylinder at 1.
The cylinder contains the filtering media, and is sealed at both ends with
meshing.
The meshing prevents organic substances from entering the cylinder.
Next the meshing comes a layer of pure wool, or other suitable material, laid
over the meshing, and next that is laid a stratum of fine prepared carbon.
Next the prepared carbon comes another layer of fine wool, or other suitable
material, and then another stratum of the finest prepared carbon. The last layer
of wool or other suitable material, is then laid over, and the whole compressed by
machinery into the cylinder E' which is then sealed with the finer meshing 7, at
the exit end.
Referring now to the Drawings —
Fig. 1 is a side elevation of the whole.
Fig. 2 is a front elevation.
Fig. 3 is a longitudinal section shewing the disposition of the cylinder and
stratas.
Fig. 4 is the end view of the cylinder.
Fig. 5 is a perspective of the cylinder.
A. is the junction with the supply.
B. is the valve regulating the flow.
C. is the outlet.

E. is the body of the Tap containing the cylinder.
E is the cylinder containing the filtering media.
e is the position of washers closing on to E¹.
F. is a worm on the face, working over the worm on E.
G is the flange, for supporting the Tap against the wall.
HH are screws fastening the flange Ĝ to the wall.
1. Meshing.
2. Stratum of wool, or other suitable material.
3. Stratum of prepared carbon.
4. Stratum of finer wool, or other suitable material.
5. Stratum of finer prepared carbon.
6. Stratum of finer wool, or other suitable material.
7. Finer meshing.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :
1. The Tap substantially as described in the specifications, and shewn in the.
Drawings.
2. The arrangement of the space S, for the play of fluid over the end of the
cylinder,
3. The face D, compressing the washers e between the ends of the cylinder by
means of a worm under F.
4. The arrangement of a filtering medium in strata' compressed into a
cylinder of brass, or other suitable material.
5. The closing of the cylinder at both ends with meshing for the purpose
described.
6. The method of having the filtering strata compressed into a cylinder which
can be removed and replaced into the Tap at will.
