I, HYMAN RUSSELL SMART 52 Solon Road Brixton Engineer do hereby declare the
nature of this invention to be as follows:-
My first improvement consists in fitting any suitable hydrostatic ventilating
apparatus with a diffuser consisting of a nozzle made of brass or other metal open
at one end and terminating in a truncated cone at the other end. A threaded
collar or its equivalent is formed round the open end of such nozzle to allow of
its being attached to the hydrostatic ventilating apparatus in conjunction with
which it is to be used while its opposite end is bisected with two or more slots
placed at any convenient angle through which the water is diffused in sheets instead
of in spray. By this means an increased volume of air is displaced while the.
volume of water requisite is diminished thus combining the two essential advantages
of economy with greater efficiency.
My 2nd improvement consists in fitting the water supply pipe or the diffuser
itself with a filtering arrangement consisting of a screen of wire gauze or its equivalent
50 arranged that any grit or other like impurity is prevented from entering the
nozzle and choking the slots therein.
In order to provide for the water being discharged from the nozzle with sufficient
force I form a taper recess in the truncated end thereof and when desirable 1
supplement this with an auxilliary conical recess which serves to gather the water
in sufficient volume to ensure its being discharged from the nozzle with the requisite
impetus.

I HYMAN RUSSELL SMART 52 Solon Road Brixton Engineer 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 consists in fitting any suitable hydrodynamic ventilating apparatus
with a diffuser consisting of a nozzle made of brass or other metal open at one end
and terminating in a truncated cone at the other end. A threaded collar or its
equivalent is formed round the open end of such nozzle to allow of its being attached
to the ventilating apparatus in conjunction with which it is to be used, or to a
suitable. junction piece as hereinafter described, while the opposite end has one or
more suitable slots formed therein placed at any convenient angle or angles through
which the water is diffused in sheets instead of in spray. Such slots are slightly
recessed in order to provide for the water being discharged from the nozzle with
sufficient force. By this means an increased volume of air is displaced while the
volume of water requisite is diminished thus combining the two essential advantages.
of economy with greater efficiency.
In order to prevent the slots in the nozzle becoming chocked with grit or other
impurity I fit the junction piece e which connects the nozzle with the water supply
pipe with a filtering apparatus consisting of a wire gauze cone f furnished with a
metal collar which fits into the mouth of such junction piece and rests upon
a rim. or flange. 9. formed therein so as to be flush with the top thereof. d is. a
washer. made of, leather, vulcanite or other suitable material which is fitted in the
head of the nozzle and against which the junction piece and the, metal collar of the
wire gauze cone take a bearing when the nozzle is screwed thereon. If preferred a
wire gauze screen may be fitted in the head of the nozzle in lieu of the gauze cone
herein before described and shewn in the accompanying drawings.
Fig. 1 of the accompanying drawings shews a view in sectional elevation of my
improved diffuser fitted with: a junction piece and filtering cone: a is the nozzle.
b the threaded collar thereof. the slots therein. d the washer. e the junction
piece. the wire gauze cone. f¹ collar thereto. g the rim or flange whereon such a
collar rests.

Fig. 3 shews an internal plan view of the nozzle a with threaded collar b and
-recessed slots c.

page_text: 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 Improved diffuser consisting of a nozzle having one or more suitable
recessed slots formed therein substantially as hereinbefore described and shewn.
2. Fitting such diffuser with a junction piece having a wire gauze filtering cone
substantially in the manner herein before described and shewn.
3. In lieu of such filtering cone fitting the diffuser itself with a wire gauze filtering
screen as hereinbefore described.
4. The combination of a diffuser nozzle fitted with a suitable washer and of a
junction piece fitted with a filtering cone all constructed arranged combined and
fitted substantially in the manner and for the purposes hereinbefore described and
shewn.
