I ALFRED DOWLING of Bolton Lodge Basingstoke in the County of Hants
Merchant do hereby declare the nature of this Invention to be as follows
The object of my Invention is to provide a simple and efficient apparatus for use
in disinfecting clothes or for subjecting matters or materials to the action of disinfecting
fumes.
I provide a chamber made air tight and provided with doors capable of being closed
airtightly there being a large door or doors for the introduction of the materials to
be disinfected and a small one at a convenient situation for the introduction of the
disinfecting agent preferably what are known as Morris's cones which will give off
disinfecting fumes. The interior of the apparatus may be provided with hooks or
supports for the materials to be disinfected and if needed also with a support or cage
for the cones. I provide the apparatus with an outlet controlled by a valve where
necessary leading to a chimney or other convenient place of discharge. In large
apparatus with the valve and outlet at top the valve may be provided with gear and
rods for operating it led down to a convenient position for operation.
When the materials and cones are introduced the doors and valve of the apparatus
are closed after the cones are lighted and the fumes fill the chamber and disinfect
the materials therein and after the desired lapse of time the valve is opened and
the fumes are discharged by the outlet and chimney or the like and when the
chamber is clear of fumes it can be opened for removal of the materials.

A Disinfecting Chamber or Appliance for Disinfecting Clothes or
Subjecting Matters or Materials to the Action of Disinfecting
Fumes.
I, ALFRED DOWLING of Bolton Lodge, Basingstoke in the County of Hants,
Merchant 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 object of my Invention is to provide a simple and efficient apparatus for use
in disinfecting clothes and other materials or matters or for subjecting them to
the action of any suitable gases, vapours, fumes or sublimates capable of destroying,
devitalizing or otherwise rendering innocuous, injurious germs and micro organisms
and thus of completely disinfecting the said clothes or other materials or matters.
My invention is also adapted for use in destroying parasites or noxious insects
and the eggs or germs thereof in or upon articles of clothing, furs, furniture,
bedding, fabrics and other materials and in or upon the coats of dogs, cats and other
domestic animals.
According to my said invention I provide an air-tight (or approximately air-tight)
chamber or receptacle of any convenient shape and dimensions constructed wholly
or in part of metal, wood, papier mâche, xylonite, india-rubber, glass, pottery-ware
or other suitable material or combination of materials and fitted with large single
or double doors (capable of being closed air tightly or approximately so) for the
introduction of the articles or materials to be disinfected or impregnated with or
treated by disinfectants, antiseptics or insecticides. The said chamber may also be
fitted with one or more small doors, traps, tubes or apertures by means of or through
which the disinfecting substance or substances, or of the gases, fumes or vapour
arising therefrom, and the interior of the said chamber may be provided with
suitable cages, shelves, trays, rods, wires or hooks or the like for suspending or
supporting the articles to be treated. The accompanying drawing is a perspective
view of a chamber constructed according to my Invertion.

The said chamber may be built or constructed either in a permanent manner as
a fixture or otherwise in a portable way for convenience of packing and trans-
port. For the latter purpose I construct the chamber with loose or separate sides
or sections such sides or sections fitting closely to each other by means of suitable
grooves, mortices, rabbets, slots, bevels, dovetails, or other devices and being secured
by pins, bolts or thumb screws or equivalent fastenings in such manner that the
parts of the chamber can be readily disconnected and reconstructed as desired.
To secure the air-tight or approximately air-tight closure of the chamber I prefer to
affix to the edges of all the doors or other openings or joints or in the frames or
lintels thereof, bands, strips or fillets of india-rubber, leather felt or other suitable
material in such manner as to prevent the ingress or egress of air, gas or vapour to or
from the said chamber other than in accordance with the objects of my invention. I

page_text: also prefer to provide the apparatus with one or more small cages, stages, stands
or other support or supports for the disinfectant or disinfectants employed and if
necessary with an outlet controlled by a shutter or valve leading to a flue, chimney
or other place of discharge. In large apparatus with the valve and outlet at the
top the said valve may be provided with suitable gearing for actuating the same
from a lower level or any other situation as desired.
As the sublimation or volatilization of disinfecting substances within a chamber
of the kind hereinbefore described is generally attended by an increase of temperature
and air pressure or tension which is liable to occasion a partial escape of air or
vapor from the chamber through any crevices, cracks or pores which may exist in
the joints of walls of the said chamber and as on the cooling down of the contents
of the chamber or the cessation of the volatilization of the disinfectant a diminished
tension or partial vacuum is thereby created in the chamber which may tend to
facilitate the absorption or entrance therein of air from the exterior before a sufficient
time has elapsed for the clothing fabrics or other articles in process of treatment
to become perfectly disinfected, I provide a contrivance whereby these objections are
obviated.
For this purpose I furnish the chamber at the side-top or bottom thereof with
bellows as shew at A or like supplementary chamber, receptacle" balloon
" or bag
of india-rubber, leather, impermeable cloth or other suitable material which is capable
of filling out or expanding when the pressure or tension inside the chamber increases
but contracts as it diminishes and thus by equalising the pressure tends to prevent
the ingress or egress of air, vapor or micro-organisms of any kind. Any suitable
form of volatile disinfectant or combination of such disinfectants may be used in
connection with this chamber but I prefer to employ such disinfectants in the
form known as "Morris's Cones" or the "Vapour Cones
" of the Chemical Carbon
Company Limited.
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 :-
A disinfecting-chamber or appliance for disinfecting clothes or for subjecting
matters or materials to the action of disinfecting fumes or for like operations sub-
stantially as herein before described whether the hereinbefore described pressure-
compensation arrangement be used therewith or not.
