of London Civil Engineer for an Invention of "IMPROVEMENTS IN THE
MANUFACTURE AND COMPOSITION OF DISINFECTANTS AND IN APPARATUS FOR
USING OR APPLYING THE SAME
"
PROVISIONAL SPECIFICATION left by the said Francis Henry Atkins at
the Office of the Commissioners of Patents on the 30th August 1883.
FRANCIS HENRY ATKINS of 62 Fleet Street in the City of London Civil
Engineer, "IMPROVEMENTS IN THE MANUFACTURE AND COMPOSITION OF DISIN-
FECTANTS AND IN APPARATUS FOR USING OR APPLYING THE SAME
'
"
The first part of this invention relates to the manufacture or composition of
disinfectants or disinfecting or deodorising agents or compounds of various kinds
by using either alone or mixing amalgamating or adding with or to other materials
or substances obtained by the chemical or mechanical treatment of water or other
liquids or by precipitation filtration evaporation or distillation whether in the
ordinary process of filtration softening or purification for public or private water
supply or by apparatus specially constructed for the purpose or similar purpose or
purposes.
The advantages gained by this part of my invention are that the substances or
materials thus obtained are usually in the form of a fine powder and frequently of
fine crystals which become suitable or available for use as disinfectants (either alone
or by admixture with other disinfecting agents) by the simple process of drying
without the cost of grinding pulverising or other operation. And also because
being thus produced or derived from another process or source some of them are
inore easily soluble in water and being so are less likely to choke drains sewers
pipes or other passages in which they are used than the substances or materials
heretofore used for similar purposes.
An important part of my invention refers to the utilisation for the purposes
named of the precipitate or substance obtained from hard water by what is
generally known as D* Clarks method of softening water as described in the specifi-
cation of Letters Patent granted to him and dated 8th March 1841 N° 8875 also in

adaptations of the said, D* Clark's, or similar methods by precipitation or filtration
(or both combined). Or I use the waste material obtained or resulting from quick
lime after the lime is exhausted by making lime water:
The second part of my invention relates to improvements in apparatus for the
simpler cheaper and better application of the said disinfecting agents or othors to
disinfecting or deodorising the effluvia of sewer gas in drains sewers cesspools and
other places
For this purpose I provide suitably constructed receptacles or vessels arranged to
contain disinfecting or deodorising powder or liquid or other disinfecting or
deodorising agent or agents so constructed as to afford or expose large surfaces of
the disinfecting agent which receptacles or vessels are hung or suspended or
otherwise affixed in the drains or sewers or beneath or above the ventilators or
ventilating gratings pipes culverta traps or other outlets.
These receptacles or vessels are charged at intervals with disinfecting or
deodorising agents or materials (liquid or solid) and will thus ensure a continuous
and prolonged action of such agents on all the sewer gas or other exhalations.
The advantages gained by this improved method of applying disinfecting and
deodorising agents are that they thus become more prolonged moro certain and
effectual in their action and avoid the danger of choking the drains or sewers by
reason of the fact that the deodorising or disinfecting agent used may be removed
when its virtue or effect is exhausted and a fresh, supply substituted.
This improved method is calculated to prolong the action of disinfectants and to
increase their efficacy to the utmost possible extent and to prevent the smells at
presont arising from open ventilators to sewers in public thoroughfares.
The third part of this invention relates to the re-dissolving of disinfecting agents
or compounds when required by the addition to them of or by treating them with
certain substances materials liquids agents or re-agents such as shall either cause
them to dissolve in water or be carried away by flushing or may on the other hand
revivify them and render them fit for being used again either in their places in the
cages or apparatus as previously described or by removal to storage places where
the process of treatment for revivification recharging readmixture or other treatment
may be more conveniently carried out.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Francis Henry Atkins in the Patent Office on the 29th February
1884.
FRANCIS HENRY ATKINS of 62 Fleet Street in the City of London Civil
Engineer. "IMPROVEMENTS IN THE MANUFACTURE AND COMPOSITION OF DISIN-
FECTANTS AND IN APPARATUS FOR USING OR APPLYING THE SAME
The first part of this invention relates to the manufacture or composition of
disinfectants or disinfecting or deodorizing agents or compounds of various kinds
by using either alone or mixing amalgamating or adding with or to disinfectants of
various kinds other materials or substances obtained by the chemical or mechanical
treatment of water or other liquids or by precipitation filtration evaporation or
distillation whether in the ordinary process of filtration softening or purification for
public or private water supply or by apparatus specially constructed for the purpose
or similar purpose or purposes.
The advantages gained by this part of my invention are that the substance or
material thus obtained is usually in the form of a fine powder and frequently of
fine crystal, which become suitable or available for use as disinfectants (either alone
or by admixture with other disinfecting agents) by the simple process of drying
without the cost of grinding, pulverizing or other operation.
And also because
being thus produced or derived from another process or source some of them are
more easily soluble in water and being so are less likely to choke drains sewers
pipes or other passages in which they are used than the substances or materials
heretofore used for similar purposes.
An important part of my invention refers to the utilization for the purposes
named of the precipitate or substance obtained from hard water by what is
generally known as D Clarks method of softening water described in the Specifi-
cation of Letters Patent granted to him and dated 8th March 1841 N° 8875, also in
the Specification of Letters Patent granted to myself and Walter George Atkins
dated 31 December 1881 N° 5745, obtained also from other modifications or
adaptations of the said Dr Clarks or similar methods by precipitation or filtration
(or both combined). Or I use the waste material obtained or resulting from quick-
lime after the lime water is exhausted by making lime water.
The second part of my invention relates to improvements in apparatus for the
simpler cheaper and better application of the said disinfecting agents or others to
disinfecting or deodorizing the effluvia of sewer gas in drains sewers cesspools and
other places.
:
For this purpose I provide suitably constructed receptacles or vessels arranged
to contain disinfecting or deodorizing powder or liquid or other disinfecting or
deodorizing agent or agents so constructed as to afford or expose large surfaces of
the disinfecting agent or agents in like manner to gas purifying apparatus the
construction of which is well understood which receptacles or vessels are hung or
suspended or otherwise affixed in the drains or sewers or beneath or above the
ventilators or ventilating gratings pipes culverts traps or other outlets..
These receptacles or vessels are charged at intervals with disinfecting or
deodorizing agents or materials liquid or solid and will thus ensure a continuous
and prolonged action of such agents on all the sewer gas, or other exhalations.
The advantages gained by this improved method of applying disinfecting and
deodorizing agents are that they thus become more prolonged more certain and
effectual in their action and avoid the danger of choking the drains or sewers by
reason of the fact that the deodorizing or disinfecting agent used may be removed
when its virtue or effect is exhausted and a fresh supply substituted.

page_text: This improved method is calculated to prolong the action of disinfectants and to
increase their officacy to the utmost possible extent and to prevent the smells at
present arising from open ventilators to sewers in public thoroughfares.
The third part of this invention relates to the re-dissolving of disinfecting agents
or compounds when required by the addition to them of or by treating them with
certain substances materials liquids agents or reagents such as shall either cause
them to dissolve in water or be carried away by flushing or may on the other hand
revivify them and render then fit for being used again either in their places in the
cages or apparatus as previously described or by removal to storage places where
the process of treatment for revivification recharging readinixture or other treatment
may be more conveniently carried out.
Having thus described the nature of my invention and the manner in which the
same is or may be carried into practice I would remark that I make no claim to
the use or application of any particular disinfecting or deodorizing chemical agent or
to any particular means or process herein before described which is well known and
in common use, But what I claim is-
First. The manufacture of an improved composition composed of disinfectants or
disinfecting or deodorizing agents or compounds of various kinds by using either
alone or mixing amalgamating or adding with or to disinfectants of various kinds
other materials or substances (obtained by the chemical or mechanical treatment of
water or other liquids) substantially such as herein before fully described.
Second. I claim the improved arrangement and application of apparatus for
disinfecting or deodorizing the effluvia of sewer gas in drains sewers cesspools and
other places by exposing large surfaces of disinfecting or deodorizing powder or
liquid or other disinfecting or deodorizing agent or agents substantially in the
manner and for the purpose herein before described.
Third. I claim the re-dissolving of disinfecting agents or compounds when
required by the addition to them of or by treating them with certain substances
materials liquids agents or re-agents such as shall either cause them to dissolve in
water or be carried away by flushing or which may on the other hand revivify
them and render them fit for being used again either in their places in the cages
or apparatus as previously described or by removal to storage places where the
process of treatment for revivification recharging readmixture or other treatment
may be more conveniently carried out substantially as and for the purpose herein-
before fully described.
In witness whercof I the said Francis Henry Atkins have hereunto set my
hand and seal this Twenty ninth day of February in the year of our Lord One
thousand eight hundred and eighty four.
