Improvements in Nozzles for Straining and Preventing Spraying of
Water, more particularly applicable to Taps.
We, ALEXANDER LUMSDEN SCIRAM, Manufacturer, of 150, Dovercourt Road,
in the City of Toronto, in the County of York, in the Province of Ontario, Canada,
and FRANK MAUNDRELL, Merchant, of Corner Canterbury & Huron Street, in the
Town of Woodstock, in the County of Oxford, in the Province of Ontario, Canada,
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:-
Our invention relates to improvements in nozzles more particularly designed
to be applied to water taps and the object of the invention is to design a simple
device whereby the water issuing from the tap may be thoroughly filtered from
sediment and the spraying of the water issuing therefiom entirely prevented
and a smooth even stream obtained and it consists essentially of a shell designed to
be fitted on to the end of a tap and provided preferably with tuple wire gauze
concavo-convex diaphragms situated intermediate of the length of the nozzle, such
diaphragms being held on a suitable shoulder and suitably held in place in the
manner hereinafter moie particularly explained
Fig 1, is a view of a plain tap with our nozzle secured thereon.
Fig 2, is a sectional perspective view of our nozzle provided with a coupling
designed for taps with a threaded lower end
Fig. 3, is a detail of the nozzle shell
Fig. 4, is a detail of the cap of the nozzle
Fig 5 is a detail of the rubber sleeve of the nozzle
Fig. 6, is a detail of the wire gauze concavo-convex diaphragms
In the drawings like letters of reference indicate corresponding parts in each
figure.

A is the tap, the lower end of which is plain. B is the shell having a reduced
lower end 6 preferably formed or spun up out of sheet metal as shown and provided
with an internally extending shoulder 6 upon which rests the concavo-convex wire
gauze diaphragms 12 and 3 The diaphragm 1 consists of a very fine mesh, the
diaphragm 2 of a mesh a little coaiser and the diaphragm 3 of a strong coarser
mesh designed to retain the other diaphragms in place and in proper forin
diaphragm has preferably flat cucumferential edges 11 21 31
The upper end of the shell B has formed on spun in it a screw thread b
Each
C is a sleeve made preferably of soft rubber, which fits down upon the top
circumferential edge of the gauze diaphragm when placed together as indicated
in Fig 2.
D is a cap, which is fitted on to the threaded upper end 6 of the shell and has
an inwardly projecting flange d whereby the sleeve is held in position The
internal diameter of the sleeve C is slightly less than the contracted lower end
of the shell, so that when the nozzle is pushed up on to the tap the gripping
quality of the rubber when compressed serves to hold the nozzle in position
Should the tap have a threaded lower end we provide a coupling E with an upper

flange e, and washer e¹, such flange being internally threaded as indicated. The
reduced lower end of the coupling fits into the rubber sleeve and the nozzle is made
entirely water tight.
We find in practice that a nozzle such as we describe constructed with concavo-
convex wire gauze diaphragms placed in the exact position in relation to each
other and close together serves to effectually concentrate the water and produce a
clear smooth stream and prevent any foreign matter or sand from issuing therefrom
In cleaning the nozzle it is necessary to remove the diaphragms and for this
purpose the cap and sleeve are first removed and each gauze diaphragm can be
cleaned separately by holding it under the tap It is essential in our invention
that the diaphragms be concavo-convex and graded as to size of mesh having the
coarsest mesh at the bottom
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same 18 to be performed, we declare that what we
claim 18
1 A nozzle for straining and preventing spraying of water from taps and the
like comprising a shell having an internal annular shoulder, three concavo-convex
wire gauze diaphragms graded so that the coarsest is at the bottom and the finest
at the top and resting on the internal shoulder and means for retaining such
thaphragmns in position upon the shoulder as and for the purpose specified
2 A nozzle for straining and preventing spraying of water from taps and the
like comprising a shell having an internal annular shoulder, three concavo-
convex wire gauze diaphragms graded so that the coarsest is at the bottom and the
finest at the top and resting on the internal shoulder, a compressible rubber
sleeve fitting on the upper face edge of the diaphragms and holding them against
the shoulder as and for the purpose specified
3 A nozzle for straining and preventing spraying of water from tapa and the
like comprising a shell having an internal annular shoulder, three concavo-convex
wire gauze diaphragms graded so that the coarsest is at the bottom and the finest
at the top and resting on the internal shoulder, a compressible rubber sleeve fitting
on the upper face edge of the diaphragms and holding them against the shoulder
and a screw cap having an inwardly projecting flange designed to abutt the top of
the rubber sleeve, such cap being screwed on to the threaded upper end of the shell
as and for the purpose specified
4. A nozzle for straming and preventing spraying of water from taps and the
like comprising a shell having an internal annular shoulder and the graded
diaphragms having flat circumferential face edges and means for exerting a pres-
sure on the faces as specified.
wile gauze
5 A nozzle for straining and preventing spraying of water from taps and the
like comprising a shell having a plurality of concavo-convex
diaphragms graded so that the coarsest is at the bottom and the finest is at the top
and resting on the internal shoulder and means for retaining such diaphragms in
position upon the shoulder as and for the purpose specified
