Improvements in Odour Diffusing Apparatus.
I, FRANK HUGHES, of the firm of Hughes, Eli and Hughes, 76 Chancery Lane,
London, W.C., Patent Agent, do hereby declare the nature of this invention
(a communication to me by John Augustus Gibbons, of Toronto, Province of
Ontario, Canada, Druggist), and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,:-
The object of the invention is to design an apparatus for holding disinfecting
fluid or perfume, which may be readily placed in position without the danger of
spilling any of the contents, and in which the vessel containing the fluid when
placed in position will automatically open and allow the fluid to escape into the
tray from which the odour is diffused in proportion.as the evaporation in the tray
takes place, and it consists essentially of a cylindrical vessel which is provided with
a neck, the mouth of which is kept closed by a ball stopper when not in
position on the open cage and tray, but which stopper when the cylindrical vessel
is placed in position on the cage and tray is forced upwardly to allow a sufficient
quantity of liquid to escape through the openings at the bottom of the neck of the
vessel and thereby partially fill the tray, which fluid as it evaporates and is diffused
through the room, is replenished from the vessel containing' the fluid, as hereinafter
more particularly explained.
Figure a perspective view showing my apparatus in position ;
Figure 2 is a sectional clevation through Fig. 1.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A is the cylindrical vessel containing the fluid; B the cage through which the
odour arising from the fluid is diffused throughout the room, and is the tray
containing the fluid from which the evaporation takes place. The apparatus is
shown secured on a bracket, but it will, of course be understood that it might be
stood on a table, or in any other suitable position.
The vessel A is secured in position on the cage B, and to the bracket by
padlocks D.
E is the neck, also preferably cylindrical in shape, which is attached to or forms
part of the vessel A, and has holes a at the top communicating with the interior of
the vessel A, and a series of holes e, made in the bottom edge communicating with
the tray C.
Near the bottom of the neck E, I place a plate F, with a circular hole f
¡n it.
G is a circular tube secured in the centre of the neck at the bottom of the
vessel A, and containing the spiral spring H.
I is a ball stopper, which has a rod h extending through it, on the upper and
ower ends of which rod are secured the cross bars or discs jj', which are designed
o keep the ball I in position. The tube G extends down to the plate, F, and has
lso a series of holes g to allow the fluid to escape. When the vessel A is secured
n position, the rod forces the ball stopper I upwardly so as to allow the fluid to
scape through the holes g, f and e out on to the tray C. When, however, the
essel A is removed, the spring H immediately forces the ball stopper I against
he circular hole f, and the flow of the fluid is stopped. K is a wick or piece of
annel wrapped around the neck E. When the fluid escapes into the tray the
apillary attraction in the flannel soaks up the fluid, so that the surface from which
vaporation takes place is very materially increased. In order to hide the flannel
rwick from view I provide a perforated cylindrical casing J, which extends from
p to bottom of the cage as shown.

page_text: After the fluid has reached a certain height slightly above the holes e, in the
bottom edge of the neck E, it stops flowing, on account of the pressure of the air
on the surface of the fluid!
It will of course be understood that the fluid is gradually replenished by
gravitation as evaporation takes place.
To further increase the diffusing properties of the apparatus I provide another
perforated cylindrical casing L, which encircles the vessel A as shown, and is
attached thereto. By this means I create an upward draught, whereby the
odour is very perfectly diffused' through the perforated sides and the top, see
Figure 2.
From this description it will be seen that I produce an apparatus for the diffusing
of the odour arising from a disinfecting fluid or perfume, very simple in construction,
and one which is readily filled and automatically regulated.
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. An odour diffusing apparatus consisting of a vessel to contain the fluid, a cage
and tray to gradually receive the fluid from the vessel, and a ball stopper to close
the mouth of the vessel when required, substantially as and for the purpose
specified.
2: An odour diffusing apparatus consisting of the cylindrical vessel A, having
holes ag neck E, having holes e at its bottom edge, in combination with the plate F,
with the hole and ball stopper I attached in position by spring H, substantially as
and for the purpose specified.
3. The cylindrical vessel A, having holes a, neck E, having holes at its
bottom edge, in combination with the plate F, with hole, ball stopper I, attached
in position by spring H, and tube G, with holes g, arranged as and for the purpose
specified.
4. The cylindrical vessel A, having holes a, neck E, having holes e, at its
bottom edge, cage B, tray C, and perforated casing J, in combination with the
plate F, with hole f, ball stopper I, attached in position by spring H, and the
tube G, with holes g, arranged as and for the purpose specified.
5. The cylindrical vessel A, having holes a, neck E, having holes e at its
bottom edge, cage B, tray C, and perforated casing J, in combination with the
plate F, with hole f, ball stopper I, attached in position by spring H, and tube G
with holes 9'; and cylindrical casing L, arranged as and for the purpose specified.
