Improvements in Apparatus for Diffusing Vapours for Disinfecting,
Medicating, or Aromatising the Air of Rooms and for other like
Purposes.
I, HAROLD BOUTTELL of 7 Bridge Street Bath in the County of Somerset Chemist
do hereby declare the nature of this invention to be as follows:-
The apparatus consists of a metal case rectangular in form and closing with a lid
which is hinged at one end. The box contains a folding metal framework to which
an absorbent band is fixed. The whole is arranged in such manner that when the box
is opened the band which is attached both to the box and to the lid is distended and
the framework is thereby spread out in the form of a fan. The band is so arranged
as to expose both surfaces to the action of the air thus giving an area of considerable
extent and when the apparatus is required for use the band is moistened with the
liquid, the vapour of which it is desired to diffuse. When the box is shut the frame
work folds down flat within it, the band also folds and the whole becomes enclosed
within the box. Except when the box is open little or no evaporation from the
moistened band can take place, the box being so formed as to close as perfectly as
may be.
The band is continuous in one piece, is fitted to the apparatus without fastening and
is interchangeable. It is held in place by being threaded over the middle one of three
parallel wires.

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 apparatus consists of a metal case rectangular in form and closing with a lid
which is hinged at one end. The box contains a folding metal framework to which
an absorbent band is fixed. The whole is arranged in such manner that when the
box is opened the band which is attached both to the box and to the lid is distended
and the framework is thereby spread out in the form of a fan. The band is so
arranged as to expose both surfaces to the action of the air thus giving an area of
considerable extent and when the apparatus is required for use the band is moistened
with the liquid, the vapour of which it is desired to diffuse.
When the box is shut the frame work folds down flat within it, the band also folds
and the whole becomes enclosed within the box. Except when the box is open little
or no evaporation from the moistened band can take place, the box being so formed
as to close as perfectly as may be.
The band is continuous in one piece, is fitted to the apparatus without fastening and
is interchangeable. It is held in place by being threaded over the middle one of three
narallel wires
Figure 1 is a vertical longitudinal section of the apparatus when open ready for
use, Figure 2 is a vertical longitudinal section of the apparatus when closed.
Figure 3 is an end view of the same and Figure 4 a horizontal section showing
the interior in plan.
a is the bottom of the case, b is the lid, and c c c are frames, these five parts
are all hinged together, the pin d serving as a hinge for the frames c.-Each of
the frames c carries at its ends parallel wires e e e and the bottom and lid single
wires f, f. The absorbent band 9 is supported by the wires e and ƒ as shown in
Figure 1 its ends hanging down.

page_text: 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. Apparatus for diffusing vapours consisting of a framework opening like a fan
and carrying a removable absorbent band substantially as described.
2. The combination of the case, the lid and the frames all hinged together
substantially as described.
3. My improvements in apparatus for diffusing vapours for disinfecting, medi-
cating, or aromatising the air of rooms and for other like purposes substantially as
described.
