PROVISIONAL SPECIFICATION.
Improvements in Filters or Strainers applicable to Water Taps
or Cocks.
1, JOHN HARVEY, of 110 Clarendon Road, Moss Side, Manchester in the
County of Lancaster, Yeast Agent, do hereby declare the nature of the said
invention to be as follows :—
The water supplied in towns through mains in many cases contains carthy matters
and insects, which should be removed before the water is used for domestic and
other purposes, and the object of my invention is a simple and inexpensive
arrangement to be readily applied to and when required removed from the supply
tap or cock, which arrangement contains filtering or straining material through
which the water must pass when leaving the tap or cock before entering the vessel
which is to receive it.
My invention consists of a tube of wood or other suitable material, wood by
preference, conical in bore and made with a recess if desired, into which strips or
pieces of flannel or felt or other suitable material are placed, and when placed the
large end of the bore of the tube is forced tightly upon the nozzle of the tap or
cock, the bore of the tube being of a size to suit the exterior diameter of the
nozzle of the tap or cock.
The flannel, felt or filtering material or a part of it comes or may come
between the bore of the tube and the exterior of the nozzle of the tap or cock.
If desired, there may be holes in the tube or other provision for cords, wires
or other arrangements for securing the tube to the nozzle of the tap or cock.
At intervals the tube is removed and the filtering material is withdrawn from it
and washed and is then replaced in the tube, or fresh filtering material may be
substituted, if desired.
If desired the tube is or may be made with a recess to receive a perforated disc
of metal or other material and above this disc the filtering material is placed within
the bore of the tube:

J, JOHN HARVEY, of 110 Clarendon Road, Moss Side, Manchester, in the
County of Lancaster, Yeast Agent do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The water supplied in towns through mains in many cases contains earthy matters

page_text: and insects, which should be removed before the water is used for domestic and
other purposes, and the object of my invention is a simple and inexpensive
arrangement to be readily applied to, and when required removed from, the supply
tap or cock which arrangement contains filtering or straining material, through
which the water must pass when leaving the tap or cock before entering the vessel
which is to receive it.
;
My invention consists of a tube of wood or other suitable material, wood by
preference, conical in bore and made with a recess if desired into which strips or
pieces of flannel or felt or other suitable material are placed, and when placed the
large end of the bore of the tube is forced tightly upon the nozzle of the tap or
cock, the bore of the tube being of a size to suit the exterior diameter of the
nozzle of the tap or cock.
The flannel, felt or filtering material, or a part of it, comes or may come between
the bore of the tube and the exterior of the nozzle of the tap or cock.
If desired, there may be holes in the tube or other provision for cords, wires or
other arrangements for securing the tube to the nozzle of the tap or cock.
At intervals the tube is removed and the filtering material is withdrawn from it
and washed and is then replaced in the tube, or fresh filtering material may be
substituted if desired.
If desired the tube is or may be made with a recess to receive a perforated disc
of metal or other material, and above this disc the filtering material is placed within
the bore of the tube.
Figs. 1, 4, 6, 8, 11, 14 and 16 are longitudinal sections.
Figs. 2, 9 and 12, outside views, and
Figs. 3, 5, 7, 10, 13, 15 and 17 are end views illustrating modifications of my
invention.
The same letters of reference are used on the same and like parts in each
modification.
Figs. 1, 2 and 3 illustrate one modification of my invention in which a, is a
tube of wood with a conical bore. In Fig. 1, it is shown applied to the nozzle it,
of a supply tap or cock.
There are strips of flannel b, or other suitable material first placed in the tube a,
in a staple form and the ends of the staple b, extend from near the bottom of the
tube a, and come up the inside of the tube and between. it and the exterior of the
nozzle, to form an elastic packing between the inside of the tube or casing a, and
the exterior of the nozzle a, and there are or may be other pieces or discs of
flannel or felt b, or other suitable straining or filtering material in the interior of
the tube a, and within the staples b.
Figs. 4 and 5 illustrate another modification of my invention in which a, is the
tube of wood recessed to hold a perforated metal disc c, above which, discs or
pieces of felt or filtering material b³, are placed.
Figs. 6 and 7 illustrate another modification of my invention, in which the
casing a, is made entirely of wood, one end of it being closed, except as to a series
of small perforations c'. ', are discs of filtering or straining material.
Figs. 8, 9 and 10 illustrate another modification of my invention similar to that
shown by Figs. 6 and 7.
When the nozzles x, of the cocks or taps are circular on their exterior the wood
casings a, Figs. 4 to 6 are sufficiently elastic when forced upon the taper nozzles
of the cocks to hold thereon and be watertight.
In the modification shown by Figs. 8, 9 and 10 greater elasticity is provided to
allow for irregularity in the form of the exterior of the nozzle by inserting into the
upper end of the bore of the casing a, a bush of cork wood d, which is or may be
secured therein by marine glue or other suitable cement or other means.
Figs. 14 and 15, show another modification similar to that illustrated by Figs. 8, 9
and 10, in which d', is a bush or ring of cork or india rubber or like elastic
material.

page_text: Figs. 11, 12 and 13 illustrate another modification of my invention, in which
a, is a casing of wood, or glass or porcelain, shaped at its upper end to receive
a ring or hoop of india-rubber or other suitable elastic material é.
In Fig. 11 the upper part of the hoop or ring e, is shewn as when upon the
nozzle a, of the cock or tap, but before being applied to the nozzle will be
contracted as shewn in dotted lines e', Fig. 11. There is or may be a hoop or ring
of metal or other suitable material f, upon the lower part of the exterior of the
hoop or ring of india-rubber e.
Figs. 16 and 17 illustrate a modification of my invention similar to that shewn
by Figs. 6 and 7, the modification illustrated by Figs. 16 and 17, being formed
entirely of vulcanized india-rubber.
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. The device illustrated by Figs. 1, 2 and 3, the tube or casing (a) formed
of wood arranged and applied substantially as and for the purpose hereinbefore
described.
2. The devices illustrated by Figs. 4 and 5, and Figs. 6 and 7 the casing (a)
formed of wood substantially as and for the purpose hereinbefore described.
3. The device illustrated by Figs. 8, 9 and 10, in which the casing (a) is formed
of wood, bushed with cork (d) substantially as and for the purpose hereinbefore
described.
4. The device illustrated by Figs. 14 and 15, in which the casing (a) is
formed of wood, and there is a ring (d) of india-rubber or other suitable elastic
material.
5. The device illustrated by Figs. 11, 12 and 13 in which the lower part or
casing (a) is formed of wood, glass pot or like material, combined with a hoop
or ring of india-rubber (e), substantially as and for the purpose herein before
described.
6. The device illustrated by Figs. 16 and 17 in which the casing (a) is formed
of india-rubber substantially as and for the purpose hereinbefore described.
