Improved Means for Preventing Water Spray in connection with
Cocks and Pumps.
I, ALEXANDER SCHRAM, of 87 Richmond Street, Wesi, in the City of Toronto,
in the County of York, in the Province of Ontario, Canada, Manufacturer, 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:-
My invention relates to improvements in water guards more particularly designed
to be applied to water taps and the object of the invention is to design a simple
device whereby the spraying of the water issuing from the tap may be entirely
prevented and it consists essentially of a guard designed to be fitted on to the end of
the tap and constructed with a wire gauze diaphragm of one or more thicknesses
situated intermediate of its length and designed to concentrate the water into one stream
as it issues from the lower end of the guard, which is constructed as hereinafter
more particularly explained.
Fig. 1 is a view of plain tap with a water guard formed to fit it.
Fig. 2 is a perspective view of a tap provided with a screwed lower end and a
water guard formed in accordance with my invention adapted to fit this class of tap.
Fig. 3. is a perspective view of a coupling designed to be inserted in an ordinary
guard in order to make it adaptable for the water tap having a screwed lower end.
Fig. 4 is a detail of the simplest form of guard adapted for a plain tap.
In the drawings like letters of reference indicate corresponding parts in each figure.
In Fig. 1, A is the tap, the lower end of which is plain. B is the water guard,
which is made in the form of a nozzle with a reduced lower end & preferably formed
or spun up of sheet metal as shown and provided at the upper end with a rubber
sleeve C. The upper end of the guard B has also formed on it a screw thread &
over which fits the screw cap D, which has a hole d in the centre so that it may be
pushed up on to the tap. The internal diameter of the sleeve C is less than that of
the hole , so that when the guard is pushed up on the tap it will securely hold it in
position by means of the compression of the rubber of which the sleeve is formed.
E and are wire gauze diaphragms situated between the lower end of the sleeve C
and the reduced end of the guard. The upper diaphragm E' is preferably much
Giner than the lower one as shown.
In Fig. 2, 1 show the tap A with a screwed end a. In order to provide a means
for holding the guard upon this form of tap I provide an internally threaded coupling A¹
having a nut-shaped upper end a' and a reduced lower end a². The end a is
designed to be inserted in the rubber sleeve C. A washer a is also provided. By
this means the connection between the coupling A' and the guard B is made
entirely water tight.
The effect of the water when turned on at the tap and passing down through
the nozzle is when it strikes the wire gauze, to concentrate the stream, should it
be a spraying one, so that it will pass down through the lower end of the guard B
in one undivided stream.
Any foreign matter such as sand in the water will also be effectually prevented
from issuing from the lower end of the guard.
In cleaning the guard it is removed from the sleeve C and inverted so that the
lower end would be turned uppermost and brought against the washer a³, thus

page_text: effectually preventing the escape of the water and directing the full force of the
stream upon the gauze diaphragm, so as to effectually cleanse it.
My invention may also be applied to pumps,
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is.
1. The combination with the tap, of a water guard, nozzle--haped in form and
provided with internal diaphragms of wire gauze or its equivalent situated inter-
mediately of the length of the guard and means for connecting such guard to the
tap as aid for the purpose specified.
2. The combination with the tap, of a water guard, nozzle-shaped in form and
provided with internal diaphragms of wire ganze or its equivalent situated inter-
mediately of the length of the guard and a rubber sleeve secured in the guard as and
for the purpose specified.
3. The combination with the tap. of a water guard. nozzle-shaped in form and
provided with internal diaphragms of wire gauze or its equivalent situated inter-
mediately of the length of the guard a rubber sleeve secured in the guard and a
screwed cap with an opening, for holding such sleeve in position as and for the
purpose specified,
1. The combination with the tap provided with a screwed lower end, of a water
guard having internal diaphragms of wire gauze or its equivalent and an internal
sleeve of rubber fitting down upon the edges of the diaphragm and a coupling
internally threaded with a nut-shaped upper end and a reduced lower end designel
to fit into the sleeve in the guard as and for the purpose specified.
5. The combination with the tap provided with a screwed lower end, of a water
guard having internal diaphragms of wire gauze or its equivalent and an internal
sleeve of rubber fitting down upon the edges of the diaphragm and a coupling
internally threaded with a nut-shaped upper end and a reduced lower end
designed to fit into the sleeve in the guard and a washer situated between the
coupling and the guard as and for the purpose specified.
