I EDWARD SOr 300 South Lambeth Road S. W. in the County of London,
Surgeon do hereby declare the nature of this invention to be as follows:-
According to my invention I generate dioxide of sulphur in suitable works &
store it in tubes or other vessels of glass at a pressure or temperature or both
combined to liquefy the same. After charging with the liquefied gas I hermetically
seal the tube by a blow pipe or other suitable means. To use the same as a
disinfectant or fumigator it is only necessary to place the tubes crossway in the
box or receptacle provided & then giving each tube a smart tap with a hammer or
other suitable article leave the room & seal the door, such tube or vessel being
thus broken or unsealed the liquefied gas is thereby released from pressure &
immediately resumes its gaseous form. It will thus mix with or difuse into the
atmosphere of the room or place to be disinfected, the said gas penetrating into
every crevice of the floor, walls, & ceiling.

COMPLETE SPECIFICATION.
Improvements in Vessels for Containing Liquefied Sulphur Dioxide
for Use as a Disinfectant and Vermin Destroyer, and for other
Medical and Sanitary Purposes.
I EDWARD Sox of 300 South Lambeth Road, in the County of Surrey,
Medical Practitioner, 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:―
This invention relates to vessels for containing liquefied sulphur dioxide for use
as a disinfectant and vermin destroyer, and for other medical and sanitary purposes,
said vessels being inexpensive to manufacture and so made that the contents can be
quickly liberated when required. In the manufacture of such vessels in accordance
with my invention 1 use tubes, bottles, bulbs, and other hollow utensils of glass or
like suitable material having a contracted orifice which after the tube is filled, is
hermetically seated by fusion in the ordinary way.
Figure 1 of the accompanying drawings shews a vessel suitable for the purpose.
Into this vessel the liquefied sulphur dioxide is passed by means of a tube.
When
the vessel is filled the tube is removed and a cap or stopper of any suitable
description is placed over or in the enlarged neck A. The contracted part B is
then placed in the flame of a blow pipe and is drawn out until the orifice is sealed
in the ordinary manner, the neck A being entirely detached. Figure 2 shews the
filled vessel hermetically sealed and ready for sale. These vessels will usually be
sold in a box or other envelope to prevent accidental breakage. The glass used in
the manufacture of these vessels is sufficiently strong to withstand the pressure of
sulphur dioxide when in the liquid form.
When used for disinfecting a room or other place the box or envelope is opened,
and the vessel struck a smart blow so as to break the glass. The liquefied sulphur

page_text: dioxide then escapes from the vessel, and assumes its normal gaseous form.
Although I prefer to use glass in the manufacture of these vessels other materials
having the same properties, and which are suitable for the purpose may be used.
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 vessel for containing liquefied sulphur dioxide made of glass or other like
suitable material having a contracted orifice through which the vessel is filled and
which is subsequently sealed by fusion substantially as described, and for the
purposes stated."
