PROVISIONAL SPECIFICATION.
An Improved Scent-cabinet.
We, JAMES MCHARDY of Fairfax House, Chiswick, Middlesex, Scientific
Expert and ARTHUR THOMAS TYER of 32 Broadway Ealing, Middlesex,
Stationer do hereby declare the nature of this invention to be as follows:-
This invention, which relates to an improved scent-cabinet, may be carried into
practice by the suitable combination of an air-chamber with an inflator or pump,
chambers or bottles for containing scent automatic valves or stoppers, spring-
nozzles, tubes, and necessary accessories.
Having constructed a suitable air chamber with an air-tight lid, we attach parts
that shall be capable of receiving and retaining the said scent-bottles, or, we
subdivide the said chamber in such a manner as, that the compartments may serve
as an equivalent to the said bottles.
The said air-chamber being provided with a pump or inflator for the forcing of
air to any necessary pressure, the said bottles, or their equivalents shall have such
valves in their stoppers as shall yield at a given pressure, but shall close when
equilibrium is restored. Each of the said bottles or scent-compartments shall have
a pay-off at its lowest point, and thereby shall communicate with a nozzle outside
the contrivance. The said nozzle shall be perfectly tight unless pressed in or
otherwise actuated by the operator, when, the pressure established by means of the
pump or inflator will drive out the scent as required.
Stopping or clogging will be rendered impossible, by causing the fluid to pass
into a telescopic nozzle tube, through minute holes. The nozzle may be actuated
in any suitable manner and constructed in various forms.
One or any number of scents may be kept perfectly tight and any, or all
may thus be drawn from the cabinet. Moreover the said nozzles may be so
constructed that a single lock and key will control their action.

COMPLETE SPECIFICATION.
An Improved Scent-cabinet.
We JAMES MCHARDY late of Fairfax House Chiswick Middlesex Scientific
Expert and ARTHUR THOMAS TYER of Ealing Middlesex Stationer 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:-
An air-tight chamber is constructed, of sufficient size and strength to form a
cabinet capable of receiving and containing any given number of bottles or com-
partments. This said air-tight cabinet provided with a pump or inflator the
action of which is to force air into the said cabinet. If the said pump be of such
dimensions as will at one or two strokes give the required pressure, it may be made
to act in the positive direction by means of a spring. In this case when the operator
pulls out the handle, the pressure will be automatically established when it is
fet go.
Instead of the ordinary stopper or cork we provide a special stopper for the
bottles or scent-compartments. This said stopper, tight in other respects, has an
air passage covered by a light valve on the inside. The air may therefore pass into

page_text: the bottle but cannot return by the same passage. The stopper has likewise a tube
passing through it and down to the lowest point inside the bottle. This said tube
communicates with a nozzle hereinafter described. Any equivalent to this tube may
be used, as for example; the liquid may pass out through a special aperture at the
bottom of the bottle and be conveyed to the nozzle by a tube not passing through
the stopper. The said nozzle is so constructed that by a spring action it becomes
perfectly tight when released and open when pressed in. This is achieved by the
following means: The outside casing consists of a cylinder of two dimensions and
may conveniently be attached to the upper side of our special stopper so as to
inclose the tube coming from the bottom of the bottle. Into this said cylinder, a
plunger is inserted. This plunger has a packing ring upon it which is a loose fit
for the lower or larger diameter of the cylinder, but fits up against the smaller
diameter, by a spring action, when released. But this plunger is hollow and is
provided with an egress for the fluid. It has also a packing which fits tightly in
the smaller diameter. Between the packing ring and the packing it is pierced by
small holes to strain sediment. When the plunger is pushed in the fluid may pass
the packing ring but it cannot pass the packing above: it may however pass into
the hollow plunger through the straining holes and thence out by any suitable
aperture. If the nozzle plungers be actuated by enlargements at the upper ends of
the plungers a suitable rising bar may be simply arranged so as to lock them out of
action, or we may provide a false top to the cabinet after the style of a sewing
machine cover in any way to lock the action away from intruders.
The action of the parts will be more readily understood as follows. If we
suppose a small cabinet constructed as described, containing say two bottles of
scent inserted, and fitted with the aforenamed parts we may operate thus: When
we pull out the pump rod and release it, the spring will cause it to force in the air,
and the valves in the stoppers will open and an equal pressure will be established
inside the bottles which are contained in the air tight cabinet. Thereupon the
scent will tend to get away from the pressure and if the nozzle plunger of one or
other of the bottles be pressed down the scent will pass by the ring packing into
the hollow plunger by the straining holes, and out by any aperture that may be
provided.
The accompanying drawings will serve to show a possible method of carrying out
the invention.

absolutely necessary.

stopper.

chamber.

(or its equivalent).

9-Packing ring on the end of the plunger, shutting off supply when forced
up, by

-Straining holes in the hollow plunger.
The action of the apparatus will be as follows; Air pressure being established by
means of the air-pump (a. b. Fig. I) the said air pressure will pass to the inside of
the bottles, through g h (Fig. II). The pressure will tend to force the liquid up
through the tube j, but as the spring r, keeps the packing 9 up against the smaller
diameter p, no escape can take place unless be pressed down.
f being pressed down, the liquid will pass the sides of the packing, 7, but cannot
pass, n n, which admits of the motion of f.
As the plunger o is hollow, and pierced by small holes between the two packing-
rings the liquid will enter it and be forced out by the nozzle-point, m, in the
direction indicated.
Having now particularly described and ascertained the nature of our said
invention, and how the same is to be performed we declare, that what we
claim is;
1. The scent cabinet particularly herein described capable of containing any
required number of bottles or compartments.
2. The air tight chamber as formed by the said cabinet.
3. A pump or inflator in combination with an air tight cabinet as herein
described.
4. The special bottle-stopper having a valve to admit air and keep in the
scent with or without a tube passing through it to the bottom of the bottle or
compartment.
5. The telescopic spring nozzle capable of shutting off the supply and straining
the sediment especially and particularly as herein set forth.
6. The combination of a means for locking the nozzles out of action, with a
scent-cabinet capable of containing any required variety of scents, in bottles or
compartments out of sight.
