Improvements in Ventilating Sewers.
I, MARION TIBBITTS of 3 Railway Terrace, New Southgate in the County of
Middlesex, Tobacconist do hereby declare the nature of this invention to be as
follows:-
-
Improvements in ventilating sewers is designed for the purpose of giving better
ventilation to sewer shafts, acting also if required as a gas lamp.
In realizing my idea I have designed a bracket of suitable shape for the purpose
of holding a glass lamp, such bracket to be attached at a given height to any sewer
shaft.
The glass lamp is of suitable shape and size, containing a door with screw handle
or otherwise, such door being surrounded by india rubber, gutta percha or any
other suitable material. Attached to the top of this lamp is a suitable metal tube
of a certain size, such tube entering the sewer shaft above the lamp at a given
distance and carried up the shaft to a certain height, with or without a cowl at the
top of the shaft.
The lamp is fed by gas running up a pipe on the outside of the shaft. The hot air
is discharged into the sewer shaft by means of the metal tube attached to the top
of the lamp, thereby creating a draught.

I MARION TIBBITTS of 3 Railway Terrace New Southgate in the County of
Middlesex Tobacconist 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 improved draught creator and lamp or lantern combined is designed for the
purpose of giving better ventilation by extraction to sewer shafts and soil pipes,
acting also if required as a lamp or lantern.
In realizing my idea I have designed a bracket of suitable shape for the purpose
of holding a lamp or lantern, such bracket to be attached at a suitable height to
any sewer shaft or soil pipe.
The lamp or lantern is of suitable shape and size containing a door with screw
handle or otherwise and surrounded by india rubber, gutta percha or other suitable
material. The upper part of the lamp or lantern is formed as a cap of suitable
metal or material such cap acting as a reflector. At the top of the cap is attached
a tube of metal or other suitable material and of suitable size, such tube entering
the sewer shaft or soil pipe above the lamp or lantern at a suitable distance and
carried up the shaft or pipe in a spiral coil or otherwise to a suitable height, with
or without a cowl at the top of such shaft or pipe.
The lamp or lantern is fed by gas or oil, the gas running up a pipe on the
outside of such shaft or pipe. The hot air is discharged into the sewer shaft or

page_text: soil pipe by means of the tube attached to the top of the cap (such cap forming
part of the lamp or lantern) thereby creating a draught.
In order that my invention may be easily understood and readily carried into
practice I will proceed to further describe the same with reference to the accom-
panying sheet of drawings.

Referring to Figure I A is an ordinary sewer shaft or soil pipe.
B is a suitable bracket for the purpose of holding the lamp or lantern.
C is the lamp or lantern.
D is that portion of the lamp or lantern composed of metal or other suitable
material and herein before referred to as the cap.
