PROVISIONAL SPECIFICATION.
An Improved Ventilator for Ventilating Buildings, Sewers, Railway
Carriages, and the like.
I CHARLES ELLIS of 24 Selby Street, Hull, in the County of York, Grocer,
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to construct an apparatus for ventilating buildings,
sewers, railway carriages and the like which shall effectively draw out any foul air,
smoke, or the like without causing any uncomfortable draughts in the said
buildings or the like. I construct my inventions as follows:-
I employ a tube or pipe of suitable thickness for inserting into the roofs or
tops of buildings, sewers, carriages and the like, this tube projects above the roof
and has an enlarged top in which are formed circular openings having short
tubular projections, suitable flanges are formed on the top and below the enlarged
part, to which are attached plates or shields to cover the tubular projections, such
shields being placed a little distance from the said projections.
The enlarged tops may be made any height and number of tubular openings
employed as may be found necessary for the size of the building for which the
ventilator is used.
For flat ventilators to be fixed in the walls of buildings and the like, I employ a
square, oblong or suitable shaped box or receptacle inclined towards the centre, for
the purpose of drawing the air from the interior of the building; this box or
receptacle has at the outer side a plate with circular openings having tubular
projections, in front of which at a little distance is fixed a plate or shield, such
shield being attached to the said box and perforated plate by bolts, pillars or any
suitable projections to hold the shield at a suitable distance from the perforated
plate.
The tubular projections may slope downwards or be bent over for the purpose of
preventing rain, soot or the like from entering the ventilator.
The action is as follows:- -When the ventilator is fixed, the wind or current of
air blows between the plate or shield and the tubular projections on the perforated
plate, passing forward and causing suction in the ventilator which draws the foul
air from the inside of the building, sewer, carriage or the like, and bears it quickly
away without causing any uncomfortable draught in the inside of the said buildings
or the like.
The ventilators may be made of iron, fireclay or any suitable metal or material,
and may have any number of tubular openings and shields as found desirable, and
can also be made any suitable shape.
Dated this Nineteenth day of January 1894.

An Improved Ventilator for Ventilating Buildings, Sewers, Railway
Carriages, and the like.
I CHARLES ELLIS, of 24 Selby Street Hull in the County of York, Grocer,
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 my invention is to construct an apparatus for ventilating buildings,
sewers, railway carriages and the like which shall effectively draw out any foul air,
smoke, or the like without causing any uncomfortable draught in the said buildings
or the like.

page_text: may also have tubular projections if desired, such holes facing away from and not
being opposite the tubular openings C in the enlarged part; but it is not essential
to employ this inner tube in all cases.
Inclined strips H are employed to allow of water running out again should it by
any means happen to find its way in at the tubular projections C, or to lodge on
the flanges D to which the shields are connected; these strips slope towards the
outside of the ventilator.
The action is as follows:-When the ventilator is fixed, the wind or current of
air blows between the plate or shield and the tubular projections on the perforated
plate, passing forward and causing suction in the ventilator, which draws the foul
air from the inside of the building, sewer, carriage or the like, and bears it quickly
away without causing any uncomfortable draught in the inside of the said building
or the like, the tubular projections causing the air to pass without entering, and at
the same time keeping out rain soot and the like.
The ventilator may be made of iron, fireclay or any suitable metal or material
and may have any number of tubular openings and shields as found desirable aud
can also be made any suitable shape.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In ventilators the employment of openings having tubular projections C for
the purposes substantially as shown and described.
2. In ventilators, openings with tubular projections, C, inner tube A with
openings having tubular projections A' inclined strips H substantially as shown
and described.
3. The improved construction of ventilator as substantially hereinbefore described
and illustrated in the accompanying drawings.
