I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 11, Burlington Chambers, New Street, Birmingham, in the
County of Warwick, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, and 322, High Holborn, in the County of Middle-
sex, Civil Engineer, do hereby declare the nature of this invention which has
been communicated to me by The New Kaiserslautern Iron and Metal Foundry
Company Limited, of Kaiserslautern, Rheinpfalz, in the Empire of Germany, to
be as follows:-
This invention has reference to water taps or cocks, and consists in certain
improvements in their construction and certain additions thereto which have for
their object the reduction of the water pressure and also the filteration of the
liquid as it passes through the tap and is used. What is meant by the reduction
in the water pressure is, modifying the flow of the water when passing into a
vessel so that the same shall run thereinto noiseless and without causing a
splashing.
The invention is preferably an additional fitting capable of being attached upon
the nozzle of the tap, but it may, for the most part, be constructed in one piece
therewith. The said fitting consists of a connection having enclosed therein a
thimble-like insertion fitted with a number of removeable and perforated caps,
plates, or layers, lying either one upon the other, or spaced, and having various
sized perforations through which the water has to pass on its way to the outlet
from the fitting. This thimble-like insertion has a circular flange upon its open
end, and is located within and carried by an enclosing sheath or sleeve-like part,
which forms the body of the fitting, connected to an intermediate piece or connec-
tion attached to the nozzle of the tap either by screwing or frictional pressure.
The intermediate piece has depending from its underside a tubular extension open
to the tap nozzle, of a diameter to fit within the metallic thimble, as aforesaid, into
which latter, for a short distance, it protrudes. The said intermediate piece is
externally screwed upon its larger diameter for the connection of the enclosing
sheath; an internally screwed socket being formed at the crown of the latter for
the purpose.
The collar of the thimble-like insertion is clamped between the underside of the
intermediate piece and a shoulder within the enclosing sheath, which firmly holds
the said sheath in position so that all water passes through the latter and through
the grid like cover plates before being used. A washer makes the joint of the last
mentioned parts a good one.
The bore of the lower part of the enclosing sheath is slightly smaller than its
body, and that part of it adjacent to the capped end of the thimble-insertion is
coned or rounded off, to overcome any resistance which might be obtained against
the flow of water.
It will be obvious that by removing the enclosing sheath the thimble-like
insertion can be removed for cleaning purposes, and also for varying its perforated
end by placing in more perforated layers, or removing some therefrom.

page_text: The perforated caps or layers are so laid one upon the other within the thimble
insertion that the outermost layer has the largest meshes, the inner layers
becoming finer towards the middle, by which means the water is filtered and its
pressure diminished.

Improvements in and relating to Water Taps or Cocks.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 11, Burlington Chambers, New Street, Birmingham, in the
County of Warwick, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, and 322, High Holborn, in the County of Middle-
sex, Civil Engineer, do hereby declare the nature of this invention (which has
been communicated to me by The New Kaiserlautern Iron and Metal Foundry
Company Ltd., of Kaiserlautern, Rheinpfalz, in the Empire of Germany) and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention has reference. to water taps or cocks, and consists in certain
improvements in their construction and certain additions thereto which have for
their objects, first, the filteration of the liquid as it passes through the nozzle part
of the tap to be used, and, secondly, the reduction or diminishing of the force or
pressure at which the water or other liquid leaves the tap or cock. By the reduc-
tion or diminishing of the force or pressure is meant: modifying the speed of the
flow of the liquid from the tap or cock extremity as it passes therefrom into a
vessel or receptacle, in order to ensure that the said liquid shall run into the vessel
or receptacle almost noiseless and without causing a splashing.
The invention may be applied to a tap or cock so that it shall form one part
thereof, but it is preferably for purposes of cleansing, cheapness and simplicity-
an additional fitting capable of being easily attached upon and detached from the
nozzle end of a tap or cock. The said invention is characterized by an additional
device in the form of a number of perforated plates, discs, or caps arranged one on
top of or near the other in pile, and preferably so that the plate with the largest
perforations shall be external to the tap nozzle or last to the flow of water, and the
one with the smallest perforations shall be internal to the tap nozzle or first to the
water flow; the said device being in communication with the bore of the tap and
within the liquid way and carried on the tap in such a manner that it can be neatly
fitted water-tight to the nozzle of an ordinary water tap or cock.
In the accompanying sheet of drawing the invention is shown constructed as an
additional fitting to an ordinary water tap, and is removably applied to its nozzle.
In the said sheet of drawing the fitting consists of a connection having enclosed
within it a thimble-like insertion or carrier, B, which is fitted with a number of
removable and perforated caps, plates, or discs, E, F, G, lying one upon the other
and having varying sized perforations through which the water has to pass on its
way to the said fittings outlet. This thimble-like insertion or carrier, B, has a
circular or other shaped external flange B2 upon its one end, and is located within
and carried by an enclosing sheath or sleeve-like part, A, by which it is connected
to an intermediate piece or ferrule, C, attached to the nozzle of the tap, W,
either by screwing, as shown, or by frictional pressure. The intermediate piece C
has depending from its underside a tubular extension D, which extends into the

page_text: top part of the thimble, as aforesaid, and directs the water from the actual tap
nozzle thereinto, and its larger diameter part C2 is externally screwed for the con-
nection thereto of the enclosing sheath or sleeve-like part A; an internally screwed
socket, A2, being formed at the top part of the sheath, A, for the purpose.
The flange B of the thimble-like insertion or carrier is clamped between the
underside face, C3, of the intermediate piece, C, and a shoulder A3 at the bottom of
the screwed socket of the enclosing sheath A, which firmly holds the said sheath
and thimble in position surrounding the tubular extension D and so that all water
passes thereinto to the perforated caps, plates, or discs E, F and G. A flexible
washer C makes water-tight the joint between the parts A, B and C.
The perforated plates, caps or discs E, F, G, which may be of any number
according to the lesser or greater water pressure on the mains, constitute an
enclosure to the lower end of the thimble-like insertion or carrier B, and they
are formed with varying sized perforations or holes and disposed within the end of
the said carrier so that the plate having the smallest sized holes or perforations is
innermost or uppermost and the plate having the largest sized holes is outermost
or lowest. This arrangement is such as to break the water pressure gradually and
to ensure the water leaving the lowest plate uniformly.
The bore of the lower part of the enclosing sheath or sleeve-like part, A, is
slightly smaller than its body, and that part adjacent to the capped end of the
thimble-like insertion is coned or rounded off to overcome any resistance which
might tend to break the flow of water from the lowest plate or disc.
It will be obvious that by removing the enclosing sheath the thimble-like
insertion, B, can be removed for. cleansing purposes, and also for varying the com-
bination of its perforated end by placing in more perforated layers or removing
some therefrom. It is also evident that the plates or discs E, F, G, can be spaced
slightly from each other and arranged so that the middle plate or plates shall have
the larger holes or perforations and the outside plates the smaller ones.
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:-
First. For taps and cocks, a pressure diminishing and filtering device charac-
terized by a number of overlying layers, plates, or discs having varying sized
holes or perforations therethrough, and which are adapted to be fitted to the
liquid ways so that the said liquid shall pass therethrough before being used,
substantially as set forth.
Second. An appliance, to be used in connection with a tap or cock, comprising a
thimble-like insertion or carrier having its one end closed with a number of fitted
overlying perforated plates, layers, or discs, and an enclosing sheath or sleeve-like
part adapted to cover up and surround the said insertion and to connect it up
centrally to the liquid way of a nozzle of a tap or cock, substantially as set forth.
Third. An appliance, to be used in connection with a tap or cock, consisting of
an intermediate piece C to be connected to the tap nozzle, and which has a tubular
extension D, an enclosing sheath or sleeve-like part A attached to the said piece C,
and which has a shoulder A³, or its equivalent, within it, and a thimble-like inser-
tion or carrier, B, surrounding the extension D and being enclosed by the said sheath.
and fixed central to the tap way between it and the piece C, and which said
Insertion is fitted and provided with a number of perforated plates, layers, or discs
adapted to overlie each other, substantially as set forth.
