PROVISIONAL SPECIFICATION
Improvements in Spray Producing Apparatus for Humidifying
Ventilating and Similar Purposes.
I, HENRY MERCER GIRDWOOD, of Broughton Flax Mills, Salford, in the County
of Lancaster, Flax Spinner, do hereby declare the nature of this Invention to
be as follows:
My invention relates to improvements in that class of apparatus for converting
liquids into very fine spray or vapour for humidifying ventilating and similar
purposes in which a jet of liquid under pressure impinges on a distributor or de-
Hector and is thereby broken up into spray and the chief object of my improve-
ments is to construct an apparatus the discharge orifices of which can be readily
cleaned when choked with dirt or grit.
In constructing my improved spray producing apparatus I employ two cylind-
rical or other suitably shaped pieces of brass or other non-corrodible metal, one of
which is arranged to be secured to the liquid supply pipe. The second piece
forms a cap or cover for the first to which it is firmly secured in any convenient
manner and the contiguous faces of the two pieces are turned or machined so as
to make a tight joint. The two pieces are then preferably pinned together or
other suitable means are employed to insure that they will always meet in the
same place when re-united after having been separated. When secured together
a very fine radial hole (or several holes) is drilled on the division between the
contiguous faces of the two pieces. The radial hole (or holes) forms a distributing
orifice through which the liquid under pressure issues and opposite each orifice is
mounted a fixed or adjustable distributor or deflector upon which the thin stream
of issuing liquid impinges and by which it is converted into very fine spray.
As an alternative instead of drilling fine radial holes to form distributing orifices
the faces of the two pieces may be set a slight distance apart so as to leave a
narrow space between them through which a very fine stream of liquid may issue
and impinge upon a deflector placed opposite thereto.
To clean the spray producer it is only necessary to slacken the cap and flush out
any dirt or grit which may have lodged in the radial holes or hetween the two
pieces.

certained in and by the following statement:-
My invention relates to improvements in that class of apparatus for converting

purposes in which a jet of liquid under pressure impinges on a distributor or de-
Hector and is thereby broken up into spray and the chief object of my improve-
ments is to construct an apparatus the discharge orifices of which can be readily
cleaned when choked with dirt or grit.
In constructing my improved spray producing apparatus I employ two cylind-
rical or other suitably shaped pieces of brass or other non-corrodible metal, one of
which is arranged to be secured to the liquid supply pipe. The second pieco
forms a cap or cover for the first to which it is firmly secured in any convenient
manner and the contiguous faces of the two pieces are turned or machined so as
to make a tight joint. The two pieces are then preferably pinned together or
other suitable means are employed to insure that they will always meet in the
same place when re-united after having been separated. When secured together
a very fine radial hole (or several holes) is drilled on the division between the
contiguous faces of the two pieces. The radial hole (or holes) forms a distributing
orifice through which the liquid under pressure issues and opposite each orifice is
mounted a fixed or adjustable distributor or deflector upon which the thin stream
of issuing liquid impinges and by which it is converted into very fine spray.
As an alternative instead of drilling fine radial holes to form distributing orifices
the faces of the two pieces may be set a slight distance apart so as to leave a
narrow space between them through which a very fine stream of liquid may issue
and impinge upon a deflector placed opposite thereto.
In the accompanying Sheet of Drawings-
Figure 1 is a vertical section and Fig. 2 a plan with the cap removed of the under
side of my improved spray producing apparatus, and Figs. 3 and 4 are two detail
views of the cap.
The body a or main portion of the apparatus is provided with a screw thread a
by which it can be secured to the liquid supply pipe, not shown in the Drawings.
The cap bis secured to the body a by a wing nut c which screws on to a threaded
stud carried by the body a.
In the Drawing four fine radial holes e are shown drilled on the line of division
between the contiguous faces of the two parts a and b, but it will be readily under-
stood that any other suitable number of holes may be made or as an alternative
a narrow space may be formed by setting the contiguous faces a slight distance
apart. A gallery f is secured by screws g to the body a and in this gallery f are
supported as many adjustable distributors & as there are holes e in this case four
distributors each of which when adjusted and set directly opposite one of the
orifices e is secured in position by a nipping screw i.
To clean the spray producer it is only necessary to slacken the cap b by partially
unscrewing the wing nut and flush out any dirt or grit which may have lodged
in the radial holes e or between the two pieces, or if necessary the cap 6 can be
taken off and the two faces cleaned in either case without injuring the holes by
passing a piece of wire through them.
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:-
1. In combination, a hollow body or main portion for attachment to the liquid
supply pipe, a cap and means for attaching the same to the body, a radial hole or
series of holes drilled on the division line between the contiguous faces of the cap
and body or alternatively a narrow space between said faces to form a distributing
orifice and a deflector or deffectors upon which the issuing liquid impinges and by
which it is converted into very fine spray substantially as herein set forth.
2. In combination, the body a, the cap b, and means such as the wing nut and

page_text: screwed stud for securing the same detachably to the body, the radial holes e and
adjustable distributors hall substantially as and for the purposes herein set forth.
