Purification of Foul Matters.
I JOHN HANSON of Wakefield in the County of York Manufacturing Chemist
do hereby declare the nature of this Invention to be as follows:-
My Invention has for its object to provide an apparatus for conveniently applying
the process of disinfecting deodorizing or purifying which is the subject matter of my
Patent No. 12,261 dated 14th October 1885, according to which process Acid is caused
to act upon substances containing Sulphites or Hyposulphites or both so as to produce
free Sulphurous Acid to act upon the matter to be treated. The apparatus according
to my present Invention is more especially applicable to the treatment according to
my said Invention the subject of iny aforesaid Patent 122615 when that last named
Invention is applied to Sewers Urinals or the like. The apparatus according to my
present Invention is constructed or arranged for convenient application of my afore-
said process to cases where the Sulphurous Acid Gas is liberated at a place other than
that at which it is generated. It consists of a closed vessel or box provided with
means for inserting and removing the materials containing Sulphites or Hypo-
sulphites or both. This vessel or box has also an opening or openings for the
insertion of a syphon or analogous arrangement or device by which Acid can be
fed or dropped onto the said materials whereby Sulphurous Acid gas is generated
and this escapes from the vessel or box for which purpose a pipe may be attached
to the closed vessel or box. This pipe leads to the place where the Sulphurous Acid
Gas is to be utilized for disinfecting, deodorizing or purifying according to my
aforesaid process and may be provided with a stopcock to regulate or cut off the
supply-At the place where the said gas is to be so utilized the pipe may be
perforated for the liberation or escape of the gas-For examplo the pipe may be
led along Sewers or along the passages or conduits through which the liquid from
Urinals flows off.

I JOHN HANSON of Wakefield in the County of York Manufacturing Chemist
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:-
My Invention has for its object to provide an apparatus for conveniently applying
the process of disinfecting deodorizing or purifying, which is the subject matter of
my Patent No. 12,261 dated 14th October 1885 according to which process acid is
caused to act upon substances containing sulphites or hyposulphites or both so as to
produce free sulphurous Acid to act upon the matter to be treated. The apparatus
according to my present Invention is more especially applicable to the treatment
according to my said Invention the subject of my aforesaid Patent No. 12,261 when
that last named Invention is applied to Sewers urinals or the like. The apparatus
according to my present Invention is constructed or arranged for convenient
application of my aforesaid process to cases where the Sulphurous acid gas is liberated
at a place other than that at which it is generated.
I will describe the apparatus with reference to the accompanying drawing which
shews its application to a sewer.
Referring to the drawing the apparatus consists of a closed vessel or box A
provided with a tightly closeable door a (which may be like a gas retort door) for
inserting and removing the materials containing sulphites or hyposulphites or both.
This vessel or box has also an opening or openings for the insertion of a syphon
or pipe or analogous arrangement or device by which acid can be fed or
dropped from a container B (provided with a closeable charging opening &²) on
to the said materials in the vessel or box A whereby sulphurous acid gas is
generated and this escapes from the vessel or box for which purpose a pipe
(C. C² (3) may be attached to the closed vessel or box A.. This pipe leads to
the place where the sulphurous acid gas is to be utilized for disinfecting deodorizing
or purifying according to my aforesaid process and may be provided with a stop
cock to regulate or cut off the supply-At the place where the said gas is to be so
utilized the pipe (at the part (3) may be perforated for the liberation or escape of the
gas-For example the pipe may be led along sewers, as shown at E or along the
passages or conduits through which the liquid from urinals flows off.
In the drawing
I have shewn a gasometer D as being inserted in the line of piping C. C² C³ for

page_text: containing a storage of gas any or all of the pipes maybeprovided with regulating and
stop cocks. 63 is a regulating cock on the outlet for acid.
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,
•
Apparatus for use in the disinfection deodorization and purification of foul matters
arranged and connected with the place containing the foul matters substantially as
herein before described.
