ERNEST MATTHEW LACEY 19 Old Queen Street Westminster, London,
Electrical Engineer do hereby declare the nature of this invention to be as
follows:-
Considerable difficulty has been experienced in the ventilation of sewers and
many appliances have been made for that purpose. Destructor ventilators such as
Holmans have been introduced whereby a current of sewer gases is drawn through
ventilating standards resembling gas-lamp-posts with and without gas-lamps, the
action of gas-jets inside causing the current and burning the gases from the sewers
as they pass. It has been found difficult to maintain an even current and they are
expensive to work. Wind cowls placed at the top of iron columns such as Boyle's
and Kite's have also been used, and fan ventilators worked by electric-motors have
been introduced to ventilate buildings. They are usually placed inside the
building or under cowl ventilating shafts.
The object of this invention is to provide sufficient ventilation of sewers at a
reasonable cost and by a somewhat similar electric motor with fan, but in
combination with electric-lamp standards.
My electrical sewer-ventilator consists of an electric-lamp standard constructed
in irou of sufficient internal_capacity to allow a current of sewer gases to pass
according to requirements. The standards may be made ornamental and similar to
well-known designs. The lower part is connected with the sewer by a pipe and
a little above the ground a space is formed in the standard to admit the fan with
electric motor, with leads and connections to take a current of electricity from the
electric-lamp leads as they pass through the standard to the lamp. The connections
are arranged in such manner that the speed of the fan may be varied as desired.
The motor may be placed round the fan-circumference or separate. A hinged door
is fixed near the motor so that the mechanical parts may be readily adjusted and
taken out when repairs are needed. The outlet for the sewer gases is made at the
top of the standard a little distance before reaching the lamp so that the flow of
sewer gases will not interfere with the light.
It is obvious that this arrangement of electric-fan with motor can be applied
in combination with gas-lamp standards.
I do not provide for burning or heating the sewer gases as they pass through
the ventilator standard, as the current properly maintained in the manner
described will be found sufficient.
Owing to the progress in electricity, especially in town lighting from central.
stations, these improvements will be less costly to adopt, easy in application and
give efficient results.

page_text: ERNEST MATTHEW LACEY Electrical Engineer 19 Old Queen, Street West-
minster, London, S. W. 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 :-
Considerable difficulty has been experienced in the ventilation of sewers and
many appliances have been used for that purpose.
Destructor ventilators such as Holmans have been introduced whereby a current
of sewer gases is drawn through ventilating standards resembling gas lamp posts,
with and without gas lamps--the action of gas-jets inside causing the current and
burning the gases from sewers as they pass.
It has been found difficult to maintain an even current and they are expensive
to work. Wind cowls, placed at the top of iron columns, such as Boyle's and
Kite's, have also been used, and fan ventilators worked by electric motors have
been introduced to ventilate buildings. They are usually placed in the side of the
building or under cowl ventilating shafts.
The object of this invention is to provide efficient ventilation of sewers at a
reasonable cost and by a somewhat similar electric motor and fan but in
conjunction with electric lamp standards.
My electrical sewer ventilator consists of an electric lamp standard constructed
in iron of sufficient internal capacity to allow a current of sewer gases to pass
according to requirements. The standard may be made ornamental and similar
to well known designs, the lower part is connected with the sewer by pipe and
a little above ground a space is formed to admit the fan with electric motor with
leads and connections to take a current of electricity from the electric lamp leads
as they pass through the standard to the lamp. The connections are arranged in
such a manner that the speed of fan may be varied as desired.
The motor may be placed round the fan circumference or separate. A hinged
door is fixed near the motor so that the mechanical parts may be readily adjusted
and taken out when repairs are needed. The outlet for sewer gases is made at the
top of the standard a little distance before reaching the lamp so that the flow of
sewer gas will not interfere with the light. It is also obvious that this arrange-
ment of electrical fan with motor can be applied in combination with gas lamp
standards.
I do not provide for burning or heating the sewer gases as they pass through the
ventilator standard as the current properly maintained in the manner described
will be found sufficient.
Owing to the progress in electricity especially in town lighting from central
stations these improvements will be less costly to adopt, easy in application and
give efficient results.
In order that my invention may be more clearly understood I attach a
drawing, Figure 1, shewing the lower part of a lamp column in section with fan
and motor in position the top of column need not be shown as any kind of cowl or
simple openings under the lamp may be made to suffice.
The lower part of column a is usually made in cast iron, b represents the branch
circuit from the electricity main for taking the current to the lamp having a
branch at c for taking a current of electricity to the notor. The switch for
placing the motor and fan in action is shown at d, and the motor e has a spindle f
with fan g attached, o represents the wires to lamp. The motor is supported upon
the plate hand may be protected by the cover j, a plate is placed at k to give
bearing to the spindle and provide openings to allow air and gases from the sewer
to pass.

page_text: The sewer is represented at 7 with outlet for air and gases at m, having a pipe n
passing into the bottom of the column. It is obvious that the current for the
motor may be taken off either by tapping the branch circuit to the lamp, as shown,
or taken direct from the lighting mains or the motor may be placed in series with
the lamp or lamps.
The door is placed inside of the column at any convenient position.
The fan is made to rotate by the motor e and a current of air and gases
produced from sewage is drawn from the sewer 1 and driven up the lamp column.
The motor may be placed round the edge of fan or in any position to give motion
to the fan.
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. In a lamp column a fan and motor is specified with reference to and illustrated
in Figure 1 of the accompanying drawing.
