page_text: I, HENRY CLARKE ASH, of 301 and 303 Oxford Street, in the County of Middlesex,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
:―
- Taps as now universally constructed have an inlet passage on one side of the plug
or valve by which the passage of water is controlled and a nozzle or outlet passage
extending from the opposite side. All such taps have this disadvantage that every
time that liquid is drawn off through them and the tap again shut there remains a few
drops of liquid adhering to the inner sides of the outlet passage and these after a
short time collect at the lower end of the outlet and drip therefrom.
In many cases as for example in taps for urns coffee pots and such like and for taps
for the hot water boilers of kitchen ranges much inconvenience results from this
dripping after the closing of the tap.
I remedy this by fixing a diaphragm across the outlet end of the delivery nozzle
with a number of perforations through its central portion. When the tap is opened
the fluid passing from the nozzle issues through the perforations without much
obstruction and without the issuing stream differing much in appearance from a stream
issuing from a nozzle having no perforated diaphragm at its outlet end.
When the tap is closed and the flow of liquid from the nozzle ceases any liquid
remaining in the nozzle is retained above the diaphragm and adhering to the sides of
the perforations in the diaphragm cannot pass down through them so that all drip is
prevented.
Preferably in all cases I fix the perforated diaphragm within a ring which can be
screwed or secured on to or into the end of the nozzle so that the diaphragm may be
removed if any solid material should collect above it.

page_text: I, HENRY CLARKE ASH, of 301 and 303 Oxford Street, in the County of Middlesex,
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 :—

the fluid passing from the nozzle issues through the perforations. without much

the perforations in the diaphragm cannot pass down through them so that all drip is

Figure 1 of the drawing annexed is a side elevation partly in section of a tap fitted
as above described with a perforated diaphragm across its delivery nozzle.
Figure 2 is an underside view of the nozzle with its perforated diaphragm.
A is the perforated diaphragm fixed approximately in a horizontal position across
one end of a short tube B which at its other end has a screw thread cut within it to
screw on to a corresponding screw thread cut on the end of the nozzle of the tap. I
do not restrict myself to this way of securing the perforated diaphragm to the delivery
nozzle of the tap as other means might be resorted to the way shewn is however a
convenient one for the purpose.
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 :-
A tap with a perforated diaphragm secured approximately in a horizontal position
across its delivery nozzle to prevent drip substantially as herein described.
