PROVISIONAL SPECIFICATION.
Improvements in Means for Drawing Off and Rendering Innoxious
Sewer and other Foul Gases.
I, CHARLES JONES, of Normanhurst, Ealing, in the County of Middlesex,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
The invention has for its object a novel combination of menus for drawing off
foul gases from sewers and other places and at the same time discharging them into
the atmosphere in a purified or innoxious condition.
In carrying my invention into effect I employ any convenient and suitable
construction of ventilating shaft, which is in communication at one end with the
sewer or other place from which the foul gases are to be drawn off; within such
shaft, near to lower or entrance end, l'arrange a draw-off fan or blower, to which
motion is preferably given by an electric motor; near the exit end of such shaft,
or at other suitable place, I arrange a heated electrode or electric furnace of any
suitable character, and I so construct this electrode or electric furnace that the
foul gases drawn off and forced forward by the fan or blower shall, before being
discharged into the open air, be brought intimately into contact with the heated
electrode or electric furnace so as to destroy the noxious character of such gases.
The electrode or electric furnace may be in the form of a horizontal grid of
platinum or other material, or it may be in the form of a hollow perforated or
reticulate cone, or of such other form as to ensure that the foul gases shall come
fully into contact therewith before escaping into the atmosphere.
I also preferably terminate the outlet end of the shaft with an ordinary exhaust
cowl to assist in drawing off the resultant gases and at the same time prevent the
entry of damp and down draughts into the shaft, and I also protect the electric
motor from damp.
Toted this 16th day of October 1894.

COMPLETE SPECIFICATION
Improvements in Means for Drawing Off and Rendering Innoxious
Sewer and other Foul Gases.
1, CHARLES JONES, of Normanhurst, Ealing, in the County of Middlesex,
Civil Engineer, 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 invention has for its object a novel combination of means for drawing off
foul gases from sewers and other places and at the same time discharging them
into the atmosphere in a purified or innoxious condition.

page_text: My invention is illustrated in the accompanying drawings, in which :-
Fig. is an elevation of a ventilating column such as may be employed in
carrying my invention into effect.
+
Fig. 2 is a vertical section of the lower part and Fig. 3 is a vertical section of
the upper part of a ventilating column fitted with my present improvements, and
Fig. 4 represents a slight modification,
In carrying my invention into effect I employ any convenient and suitable
construction of ventilating shaft a, which is in communication at one end by a
tube b with the sewer or other place from which the foul gases are to be drawn off;
near its lower or entrance end I arrange a draw off fan c or blower, to which
motion is preferably given by an electric motor d of any suitable construction,
which latter I protect from damp by a suitable cover e; near the upper or exit end
of such shaft a or at other suitable place I arrange a heated electrode or electric
furnace of any
suitable character and I so construct this electrode or electric
furnace that the foul gases drawn off and forced forward by the fan or blower
shall, before being discharged into the open air, be brought intimately into contact
with the heated electrode or electric furnace so as to destroy the noxious character
of such gases.
The electrode or electric furnace may be in the form of a series of horizontal
grids of platinum or other material as illustrated at Fig. 3, or it may be in the
form of a hollow perforated or reticulate cone as shown at Fig. 4, or of such other
form as to ensure that the foul gases shall come fully into contact therewith before
escaping into the atmosphere.
I also preferably terminate the outlet end of the shaft with an ordinary exhaust
cowl g to assist in drawing off the resultant gases and at the same time prevent the
entry of damp and down drafts into the shaft a.
1 would here remark that I have not thought it necessary to give details of the
construction of the draw off fan or blower, nor of the motor, electric furnace and
cowl, as separately they form no part of my invention and any suitable construction
of such parts may be employed.
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 :-
CLAIM.
In means for drawing off and rendering innoxious sewer and other foul gases, the
combination with a tube or column, of an exhaust fan or blower, a motor to rotate
the latter, a cover to protect the motor from damp, and a heated electrode or
electric furnace, with or without an exhaust cowl, substantially as herein shown and
described.
