PROVISIONAL SPECIFICATION.
Disinfecting Ventilator or Sewer Gas and Germ Destroyer.
HENRY GEORGE DUNSTAN, of 37, Maindee Parade, Maindee, Newport, Mon.,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct a disinfecting ventilator for w.c.
soil pipes sewer and house drains, in such a manner that all sewer gas or germ
arising therefrom in passing through either way of the w.c. soil pipes, sewer or
house drains, is destroyed, thereby obviating the risk of disease arising 80
surceptible under the present system.
I arrange the disinfecting ventilator to be built inside the boundary wall of
any public or private building, dwelling house, or any other place of abode, in
close proximity to the trap or syphon of the main sewer.
By arranging the disinfecting ventilator in the position already referred to, I
am enabled to counteract the evils of sewer gas or germ arising.
In carrying this invention into effect I employ cast iron or any other suitable
material, in constructing the disinfecting ventilator of the required length,
breadth or thickness which I make in the form of a square or semi-circular
shaped vessel; with a square perforated plate, at front of the said vessel, and
suitable fastenings for securing same. Also, a sprigget pipe attached to the said
vessel, with a beaded end, so made as to firmly hold the said pipe in proper
position with the w.c. soil pipe.
I also construct a perforated circular plate to fit inside of the said vessel, to
prevent any material or substance obstructing the trap or syphon.
According to this invention I arrange suitable vessels or receptacles for con-
taining the disinfectant.
The disinfectant can be used either in block perforated form, powder, or
liquid to be placed in the said vessels accordingly.
The disinfecting ventilator is easy of detach in case of stoppage to the trap
or syphon.
The present system of ventilation being non-effective, any injury to this part
of the boundary wall admits the escape of sewer gas or germ, thereby making
the same very dangerous.
According to my invention, the disinfecting ventilator is protected by its
own construction thereby dispensing with all risk in the escape of sewer gas or
germ, if such should arise.

I, HENRY GEORGE DUNSTAN, of 37, Maindee Parade, Maindee, Newport, Mon.,
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 this invention is to construct a disinfecting ventilator or sewer
'gas & germ destroyer for w.c. soil pipes, sewer and house drains in such a
manner that all sewer gas or germ arising therefrom in passing either way of
the w.c. soil pipes, sewer or house drains is destroyed thereby obviating the
risk of disease arising, so surceptible under the present system.
I arrange the disinfecting ventilator to be built inside the boundary wall of
any public or private building, dwelling house or any other place of abode, in
close proximity to the trap or syphon of the main sewer.
By arranging the disinfecting ventilator in the position already referred to, I
am enabled to counteract the evils of sewer gas or germ arising.
In carrying this invention into effect, I employ cast iron or any other suitable
material, in constructing the disinfecting ventilator of the required length,
breadth or thickness, which I make in the form of a square or semi-circular
shaped vessel, with square perforated plate at front of the said vessel, and
suitable fastenings for securing same. Also a sprigget pipe attached to the said
vessel. with a beaded end, so made as to firmly hold the said pipe in proper
position with the w.c. soil pipe.
I also construct a perforated circular plate, to fit inside of the said vessel, to
prevent any material or substance, obstructing the trap or syphon.
According to this invention I arrange suitable vessels or receptacles for con-
taining the disinfectant.
This disinfectant can be used either in block perforated form, powder, or
liquid, to be placed in the said vessels accordingly.
The disinfecting ventilator is easy to detach in case of stoppage to the trap
or syphon.
The present system of ventilation being non-effective, any injury to this part
of the boundary wall, admits the escape of sewer gas or germ, thereby making
the same very dangerous.
According to my invention, the disinfecting ventilator is protected by its
own construction, thereby dispensing with all risk in the escape of sewer gas or
germ if such should arise.
In order that my invention and the method of carrying the same into effect
may be more readily understood, I append hereunto one sheet of drawings.
(A) Being the square perforated plate at front of the said vessel.
(B) Being the sprigget pipe attached to the said vessel, with a beaded end so
made as to firmly hold the same in proper position with the w.c. soil pipe.
(C) Being the perforated circular plate fitted inside the said vessel to prevent
any material or substance obstructing the trap or syphon.
(D) Being the square or semi-circular shaped vessel, as applied to a, b, and c.
This containing smaller vessels or suitable receptacles for the disinfectant.

page_text: Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
The manufacture and use of the disinfecting ventilator or sewer gas and germ
destroyer for w.c. soil pipes, sewer and house drains constructed substantially
as herein before described and represented in the accompanying drawing.
