PROVISIONAL SPECIFICATION.
Improved Disinfecting Apparatus for Drains, Sewers, and the like.
I JOHN SHAW, 22 Rosehill Terrace, Willington on Tyne, Northumberland Iron-
founder do hereby declare the nature of this invention to be as follows:-
It consists of a Vessel made of sanitary glazed, or enameled Earthenware, Cast
Iron, or other material, placed in the catch pit alongside the Manhole shaft. If there
be no catch pit, it can be set into the earth alongside the manhole shaft, with a con-
nection. It is protected by a cast Iron case which is divided into two compartments,
one is to protect the Vessel, the cover of this part is air tight, the purified gasses pass
from it to the other compartment which has an open grate to allow the purified gas
to pass out, this compartment has a receptical inside which collects the water and dirt,
and which can be lifted out to empty when necessary. The same can be applied to
Drains.
.
For Water Closets the Vessel can be applied under the seat if necessary, with
outlet pipe going through the wall into the open air.
The purifying element consists of pieces of Coke saturated with Paraffin Oil.
When the Vessel is fixed it is filled with the saturated coke, then more oil is poured
on the coke. What the coke does not absorb falls into the bottom of the Vessel, if
necessary a little oil of peppermint can be applied.
The Coke will last for years the cover can be taken of when necessary and more
oil applied.
The vessels can be made any demensions to suit the size of Sewer or Drain.

1 JOHN SHAW 22 Rosehill Terrace Willington on Tyne Northumberland Ironfounder
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:
It consists of Vessel A Fig. 2. made of sanitary glazed or enamelled Earthenware,
Cast Iron or other material, placed in catch pit alongside the manhole shaft. If there
be no catch pit, it can be set into the earth alongside the Manhole shaft or flushing
shaft with connection B Fig. 2. It is protected, by a Cast Iron case, which is divided
into two parts. C Fig. 2. is to protect the Vessel. The cover of this part is air
tight. The purified gas passes from it to the other D Fig. 2 which has an open
grate E to allow the purified gas to pass out. F Fig. 2. is a receptical inside case D
Fig. 2. which collects the water and dirt, which can be lifted out to empty when
necessary.
The same can be applied to drains and flushing shafts.
For Water Closets the Vessel A Fig. 2. can be fixed in any corner of the closet, or
be fixed outside in the open air with a connection through the wall from the top of
S trap to the Vessel.
The purifying element consists of pieces of Coke or other porous material saturated
with paraffin or other oils. When the Vessel A Fig. 2. is fixed it is filled with
saturated coke or other porous material. Then more oil is poured on the coke or
other porous material. What the coke or other porous material does not absorb falls
into the receptical at bottom of Vessel A Fig. 2.
If necessary a little oil of pepper mint can be applied after the Vessel is charged.

page_text: The coke will serve for years. The cover can be taken off when necessary and
fresh oil poured on the coke or other porous material.
The Vessel A Fig. 2. can be made any demensions to suit the size of Drain or
Sewer.
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―
1. The use of Vessel with inlet at side and receptical at bottom.
2. The use of Paraffin or other oils as a disinfecting medium.
3. The use of Coke or other porous material as a medium for distributing the oils,
which allows a free passage for the gasses.
